You need to put the CDN URL in the path, with /[BuildTarget] on the end..

[steep lichen]

hostname from pull zone?
name.b-cdn.net/[BuildTarget]
and should i put it in BuildPath too?

because none of this works and drops exception:

[undone hound]

where's the https://?

the build path is the path to where the addressables should be built to on your machine.

ServerData/[BuildTarget]

Will put it in <drive>/UnityProjects/ProjectName/ServerData/Android

[steep lichen]

oh, got it.
https is present by the way, still throws exception

[undone hound]

it's difficult to help when you don't provide things exactly as you have them.

name.b-cdn.net/[BuildTarget]

This doesn't look very unique. How is the CDN supposed to point to your bucket (or whatever name they use)

[steep lichen]

i should stop making examples and just show screenshots instead, i guess

[undone hound]

is creobitdata unique to you?

[steep lichen]

it would be surprise if it is not, but i get your point.
i'll try something more unique

[undone hound]

I haven't used this platform you are, no idea if
creobitdata was given to you -> fine
is the host -> not fine
is something you added -> fine

[steep lichen]

i just follow the tutorial because this thing is needed for one test program for job offer, so i'm also in the dark here, and running out of time a little

it is something i added

[rancid wigeon]

whats the correct way to check if an asset reference is already loaded so not to load it again?

unity has not got very good code samples to learn addressables

[rancid wigeon]

I tried IsDone and IsValid but neither of those seem to be correct

[foggy widget]

Are Addressables a good way to make Scriptable Object references into savable data?

I have this idea of using Newtonsoft alongside Addressables, to make inventory items in my game use an Addressable "Asset Reference" that leads to the Scriptable Object they're meant to use.

[steep lichen]

i'm going insane here.
addressables throw Invalid URI: Invalid port specified. exception on pretty much anything i put in LoadPath.
i tried a lot: CDN, local FTP, local directory, native RuntimePath.

i'm guessing here that my addressables are just broken.
Any ideas?
Or better yet, any way to unpack bundles manually in code? Cause i think loading and unpacking them manually will be better solution now

fucking nevermind me

it works now

Now i know that you have to rebuild assets

[quaint locust]

What are addressables and what do they do?

[frigid stag]

I usually check if .Asset is null

[rancid wigeon]

yeah im doing that aswell but i find it confusing what IsValid and IsDone is suppose to be

the docs kind've suck at explaining them

[frigid stag]

IsDone is when the loading operation as been done and IsValid seem to be if you can try to load the assets. At least from what I have seen.

[rancid wigeon]

so IsDone is true if essentially .Asset is not null?

[frigid stag]

It can fail I believe. If like it isnt valid I believe

I had issue earlier when trying to only use IsDone

So I used .Asset to check

[rancid wigeon]

@frigid stag quick Q, if you add a scriptable object as an addressable and it references a unity object say a mesh file, does that mesh file also need to be marked addressable or is it automatically done for you

[hoary rampart]

All dependencies are included in the build, and that is a dependency

[rancid wigeon]

ah so i dont need to mark them as addressable unless i want to load those mesh files by themselves in other situations

[rancid wigeon]

rebuilding addressables every time i change something is such a slow down on dev time

[frigid stag]

It is, but you can usually get away with simply using the AssetDabase in Editor. Also, you do not need to build everything, if you are working on a considerable project, you can build some of the addressable that you need. No need to build 20 maps, if you only need 1 for your test.

[paper frigate]

is there a way of speeding up the loading for these addressable prefabs that include models. The initial loading is quite slow. After loading them once, they are in the cache, even after restarting the application (which makes testing speeds quite annoying because I can't find a way to empty it)

Any setting I could change to make the intitial loading faster? Online I read a lot of conflicting things e.g. using unitywebrequest is faster even if the files are local (but this would only apply for android?). Also uncompressed is faster than LZ4?

[viral cairn]

i just downloaded unity and its using thunderoad (which is the game thing for b&s) and while its loading the timer stops and it doesnt load

whats the problem?

[remote lantern]

This might be a dumb question, but does the Android platform support Addressables (prior to the Addressables for Android for Unity 2023)?

I've been using Addressables for PC (Unity 2019 and 2020) for a while and thought that mobile was supported, but I'm really struggling to get a working apk with addressables and Asset Bundles. Is there something I'm missing? When I build out, the apk is smaller than expected and no addressables load, so they files must not be present. Is there a StreamingAssets folder in the Android build folder I can move them to manually?

There are no plans for a Google Play store release, so hacks are welcome.

[hoary rampart]

you need to build addressables bundles separately for each platform

[stuck wolf]

Hi there, I have a question that's stumping me... In the cloud build I have written a PostExport script and configured it; this script is being called and what it does is it Brotli compresses all of my Addressable files one by one and then it deletes the original .bundle files. I have debug logged to confirm it works in the cloud build. So far so good. ✅ Now, when I try to click the 'Download Addressables' button in the Build History I get the good old zipped folder with the .bundle files instead of my .br files... HUH? 😆 Does anyone know why this would happen?

Solution: Hey everyone so in the end by logging things we came across the fact that the download button downloads from a certain path on the cloud server. You can use the following path to reach there. Hope this helps someone who comes across it! ${WORKSPACE}/.build/last/${BUILD_TARGET}/extra_data/addrs/

[bitter root]

is there no true way to background download addresables in webgl? 😐

all download methods freeze my game until the download finishes 😐

I mean, I can do it in javascript 😐

it's just fetch and continue with your life

[remote lantern]

@bitter root Unfortunately not -- WebGL only has a single thread available to it.

[remote lantern]

Thank you for the reply. The problem was that I didn't know the semantic difference between [] and {} in the addressable paths.

[bitter root]

I found CachedFetch.js inside the editor installation folder...
Maybe I can fix him? 🥹

[bitter root]

99.9% of the way there... now I only need to get a list of all addressable bundles...

unity catalog ain't helping 🥲

[storm cove]

hello can anyone help me with this errors, the build of the addressable is field and I don't know how to fix that

[next inlet]

Is the file path over 256 characters? If so, it is likely the common file path limit issue on windows

You can try this: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/The-Windows-10-default-path-length-limitation-MAX-PATH-is-256-characters.html#:~:text=By default%2C Windows uses a,Files%2C Paths%2C and Namespaces.

Or you can move your assets so they are closer to the root Assets folder, keep folder paths as short as possible, and keep the asset names as short as possible

[late agate]

Are Addressables the recommended solution for storing things like ScriptableObjects? I have a bunch of Weapon & Armour scriptable objects and am wondering what the best way to store them and reference them is so I can reference them later in code (like when a weapon is equipped to find the weapon scriptable object and attach it to a player class)

[rustic scarab]

It's a recommended solution if you want to manage and load things by simple keys and labels regardless of the actual file paths.

[warm talon]

Hi

How can I fix this??

I use addressables to load audio clips

When I load this from bundle I have this error(

[next inlet]

HI all, my team is trying to decide between two strategies for packing Addressables. The game uses a dynamic streaming solution where assets are organized into cells, and different cells of content are loaded/unloaded as the player moves around the world.

Strategy 1: The Game Object Prefabs that are actually loaded/unloaded are organized into Addressable Groups by content type. At the moment this means Terrains go into one group, and non terrain goes in a separate group. For the terrain, Pack Separately is used, so each terrain gets packed into its own bundle. For the non terrain, there can be multiple prefabs per cell, so all prefabs that are associated with the same cell get the same label, and Pack by Label is used. So basically the content that is loaded/unloaded together can be packed into the same bundle. For dependencies (meshes, shaders, materials, etc.), everything is placed in a single Group that is Packed Together, with the idea being that most of these assets will be needed no matter which cell the player is in.

With this strategy, most of the memory used by the prefabs is freed right when each cell is unloaded, which is optimal. Some memory from the dependencies might not be freed even though it could be, however Resources.UnloadUnusedAssets can be used as a fail safe if memory grows too large.

Strategy 2: All prefabs (terrain and non terrain) and dependencies are placed in a single Addressable Group set to Pack Together.

With this strategy, Resources.UnloadUnusedAssets has to be called fairly regularly since assets from the single bundle aren't unloaded automatically. This results in noticeable lag during game play.

You might be thinking, Strategy 1 is the obvious winner, however there is a conundrum that we can't figure out that is confusing the issue. On both my PC and iPhone, RAM usage is nearly identical between the two strategies. However, on my teammates iPhone 13, he is crashing upon startup and says the memory is going over 3GB.

_ _
Yet with Strategy 2, he does not have this problem.

_ _
This isn't making sense to me, as as far as I can tell there are not enough additional asset bundles with Strategy 1 to make a difference (they are KB's in size). So two questions:

1. Does your understanding of the packing modes support the notion that Strategy 1 should be the winner, and not result in a large increase in RAM usage?

2. Does anyone have any ideas as to why RAM usage might be higher with Strategy 1? Is there a possible Addressable Setting somewhere that could be causing this, or must it be something unrelated (some bug or other issue)?

Sorry for the long question!

For reference, this is the build report for Strategy 2.

And this is the build report for Strategy 1. As you can see there is hardly a difference in the size of the output

I also checked the catalog sizes to see if there was a big difference. There was not

Also perhaps worth mentioning. My teammate is using a PC to build the addressables for iOS, using the well known hack. Whereas I am running two tests. One for a Windows Build on PC, and one for an iOS build using a Mac. Is it possibel the use of the PC to make the iOS addressables is somehow resulting in the RAM difference?

[hoary rampart]

what does the profiler say about the RAM usage?

[next inlet]

@hoary rampart On my systems the RAM usage is nearly identical for both strategies with Memory Profiler. My teammate has not been able to test either strategy with the profiler, because strategy 1 crashes on load and also due to some quirk with building the addressables on PC for iOS, he is not able to connect to the editor.

[candid pelican]

@next inlet pls have a look at addressables best practices pinned in the channel.

[warm talon]

I have sprite atlases that are included in the addressables, the Include in build checkbox is disabled

Tell me the correct way to load sprites from this atlas into objects on the scene? What is the best way to do this?

[next inlet]

Thanks. I just read through that and it supports my thesis that strategy 1 is better for an open world mobile game. However, my teammate is quite sure that strategy 1 is causing crashing due to high memory use.

Do you think this is remotely possible or must something else be going on?

Everything I have read says that having more bundles can possibly increase memory use, however from what I have seen the bundles are each only KB in size.

The other concern mentioned a lot is the increased catalog size, but I haven't seen much of a difference between the two strategies

[hoary rampart]

you should really do some profiling to see how many bundles are actually loaded in memory at a time, on different devices. The different bundle builds could be the culprit but it's hard to say at this point

[frigid stag]

Profiling is the best way to know what is happening. You can easily look into which bundles are loaded and what are the issues.

[neon pilot]

Hi there! how is going guys? i have a question about addressables because i use "cutsceneinstanced" gameobject to access his playabledirector and do play, but when i release it it remaining the gameobject in scene, i need to destroy it? chatgpt ask and told me its not necessary to be destroyed but then is reamining in scene with all content of the cutscene

[neon pilot]

well, after search in google unity docs, community, etc.. i cant find a solution but in my hierarchiy remains the gameobject

if i did this its clean then

[candid pelican]

@neon pilot since u r instantiating it manually so u have to destroy it manually too. If u use instantiateasync function of addressables class release function will handle the deletion for u. This is also explained in the documentation

[neon pilot]

omg! i forgot this and is very basic! so thanks so much for support 😉 i just tested and you are right it works fine now without. destroy

[prime relic]

I surely cannot be the only one encountering this. Addressable builds seem to ignore Animation Clips embedded inside models (e.g. fbx), and even though the model is marked as "Addressable" (and also the clips on the animation tab), they are simply ignored and not included in the Addressable build

Worse, the Animation clips are all extracted and included in the base build (Which is critical as this prevents making a Google Store submission when you are trying to keep the base build size down)

Additionally, the same happens with "sub meshes" of a model, which are also only extracted to the base Unity project and skipped in the Addressable build.

Thoughts anyone?

Also created this discussion post
https://discussions.unity.com/t/addressables-build-is-packing-animation-clips-anim-and-mesh-data-mesh-in-base-project/1502261

Yes, If I separate the clips out of the model, they can be packaged. But this requires you to also remove them from the model, else you just have duplication.

[prime relic]

OK, after further examination, it turns out the Animations and Meshes are actually in the Addressable Bundle. HOWEVER, they are also duplicated in the base build #facepalm

Anyone got any ideas for how to exclude these?

[candid pelican]

@prime relic are u referencing ur fbx or its prefab in a script or scene ?

[next inlet]

Our team is using Unity 2022.3.32f1, and we are seeing some performance issues related to shader loading/unloading when using addressables (Shader.ParseMainThread and Shader.MainThreadCleanup). What is the recommended way to deal with this? Using Shader Variant Collections?

I read from a Unity person on the forums that they were working on getting this shader loading/unloading work onto a background thread, but that was back in 2019 and I can't find any information on whether this was ever added in a newer version of Unity. Anyone have any clue?

[prime relic]

No, all prefabs are instantiated at runtime using dynamic configuration.

Essentially what seems to be happening:

1: The Addressable build process runs
2: It unpacks the Models for build
3: Creates the addressable packs
4: Removes ONLY the model file itself from the build
5: packages everything that is left in the core build

Seems to be a genuine bug in the Unity build system, which surprises me that it has existed for so long
(Confirmed the same in a test project with ONLY the model file, not even a scene)

I've created a custom build script which actually deletes the built folders after the addressable build which seems to resolve it.

However, now I'm having issue trying to run the "Play Asset Delivery" build script for Addressables instead of the default build.

Very little docs anywhere on how to build custom build scripts with addressables in C# (which is needed for automation)

Anyone got any thoughts on how to change a default build script (as shown below), to one that will use the "Play Asset Delivery" addressable build script?

    [MenuItem("Build/Custom Build with Addressables")]
    public static void BuildGame()
    {
        // Step 1: Build Addressable Data
        AddressableAssetSettings.CleanPlayerContent();
        AddressableAssetSettings.BuildPlayerContent();
        // Need to build "Play Asset Delivery" script and not default
    }

[prime relic]

OK, this seems to hint at how to customise the Addressables Build

https://docs.unity3d.com/Packages/com.unity.addressables@1.21/manual/ContinuousIntegration.html

OK, progress, it is a little destructive and likely only actually useful for automation (unless you like Git revert "a lot") but essentially the process is like this:

1. Perform an Addressables build using the "Google Play Delivery" profile
2. Remove the folders containing the packed content
3. Run a Unity Android build
4. Profit

Critically
You must ensure that the "Addressable" build settings are set to NOT build with the project to avoid the addressables trying to build twice.

Also, only use the custom build script during automation, or with a folder projected by git (to recover what was removed).
Possibly you might be able to rename the folder(s) your packed content was in with a "~" prefix, then rename it again afterwards

Actually, might try that now

Addressables.LoadSceneAsync has an activateOnLoad parameter that can be used to delay the activation of the scene, which is great. Is there some way to do the same when using Addressables.LoadAssetAsync?

I need this because I have tracked some performance issues down to the Single Frame Integration of multiple Addressable Assets that I queue up to be loaded at the same time. Without any control over the loading, the assets end up getting "integrated" all at once, whereas if I could delay the integration, I could control it in an orderly fasion (only allowing x assets to be integrated in a single frame).

I know I could probably load each one individually, but as far as I can tell the actual loading does happen on a background thread and doesn't impact the game, so queuing them all up at once results in faster loading.

[next inlet]

It's quite strange that there is no mechanism for doing this considering every other Async load method has this functionality.

[slate timber]

Where can i find "what is changed between versions"? There is no "What's new" tab

[peak kraken]

Is it weird to store an asset reference as a field of a gameobject for help keeping track of instance count and then unloading when it reaches zero

[hoary rampart]

the changelog tab

[somber crypt]

on android I always get a hang on first load after install.
the first thing I do is download the basic app dependencies. it's failing to find a key file, but I think it's trying to access it too soon. on second load it works. code attached

maybe it's my shitty progress bar

hmm nope. it's an addressable error. I think I can replicate it with a dev build maybe

it spends quite a while downloading, it's just that after that addressables can't find the file I need

[somber crypt]

in the end I just force-restart the app on android after the first download

that worked

[slate timber]

Does anyone know why the first addressable request takes so long, the subsequent calls are fine

[slate timber]

: o

[slate timber]

Im using simulate groups i

Asset db dont really simulate the request does it?

[candid pelican]

nope it doesn't

[slate timber]

Man addressables are so meh

var sceneLoadHandle = _addressableScene.LoadSceneAsync(LoadSceneMode.Single);

If i yield return this it hangs forever

No error

funnily enough this only happens the first time when i dont have the file

It downloads it fine, but dont load the scene

If i reload my game and the file is downloaded itll load the scene

[slate timber]

LoadSceneAsync gives me this:
Scene 'Assets/Scenes/UIs.unity' couldn't be loaded because it has not been added to the build settings or the AssetBundle has not been loaded.

And it only happens on the build not editor

[slate timber]

did you manage to figure this out? having same issue on a win build

seems like 1.21.20 has issues?

aware of a bug but dont attempt to reproduce

great

time to make a new repo

[slate timber]

yep so addressable scene loading is broken for all of 1.2.0

repro repo https://github.com/JayArrowz/AddressableSceneBug

[shell lichen]

addressables have been broken since release tbh

[slate timber]

Any alternative you know of? I kinda dont want to downgrade

The only thing which is a issue rn is the scene loading

[shell lichen]

asset bundles

[shell lichen]

load t he scenes from asset bundles until they fix the scene loading

[slate timber]

hmm dont the asset bundles get loaded in memory though

This is the behavior i was trying to prevent

[shell lichen]

only if you call assetbundle.load

[slate timber]

ah

ty

[shell lichen]

np

another alternative

you could serialize the scene to a json file

like save all the objects and their position and all components on the object etc to a json file then instantiate it all one at a time

will work fine for small scenes

but prolly not so w ell for large scenes

[slate timber]

ic ty im going to try the asset bundle stuff and see if it works

[molten stone]

I ran the analyzer and it decreased build size by putting everything in the duplicate asset group. I then moved parts of it(the characters and all assets they use) into a different group and build size increased again. The characters group doesn't reference any bundles and it is not referenced directly either(only by assetreference). What am I doing wrong? Am I not supposed to group assets used together?

[slate timber]

So the different group you need to make sure the settings are set to remote

if you select the group, it should show the settings in the unity editor

Note how my build and load paths are remote

[molten stone]

I'm not deploying on a remote server. Why would this affect build size?

[slate timber]

If you set it to local, it will include the whole groups assets in the build

all my groups are set to remote. So the build dont include all my assets. I use this to download it https://github.com/JayArrowz/AddressableSceneBug/blob/main/Assets/LoadingScreen.cs

even my scenes are set to addressables (But this is bugged iin addressable 1.2.0+)

[molten stone]

It's an offline game. I can't make it remote.

My scenes are addressable too

[slate timber]

i only said this because your original question mentioned decreasing build size

The only way i've seen the ways to decrease build size is if the assets aren't actually in the build and served remotely

You can use compression like LZ4HC

to decrease it further though

[molten stone]

Maybe. But the issue is that the build size is low(1.69gb) if I leave everything in the jumbo duplicate asset isolation group. If I group related assets into another group the size jumps(3.6gb).
Am using LZ4HC

[teal mortar]

if you separate things into different bundles and the total size increases that's a pretty surefire sign that there's references you're not aware of still causing duplicate assets, if the analyzer isn't being very helpful you could try this: https://docs.unity3d.com/Manual/AssetBundles-Browser.html to inspect what's in the built bundles

[molten stone]

Thanks. I'll try using this.

[rocky ember]

Hey folks! If I load a particle effect prefab from an Addressable, it has no material in builds (or in editor while using the existing build). The Addressable Report lists the material under the prefab. Any idea what's going on there?

[solemn apex]

well that's... sad. I was trying to make an experiment to make maps in a different project and just have my main project load the assets from an online bucket. That way I wouldn't have to update the maingame everytime I make a map. So this isn't possible?

[slate timber]

No you'll have to downgrade addressable version

No reply on forum too

Looks like they don't give a toss

[coral sentinel]

Where do you guys host your addressables?

[warm talon]

Hi
we are loading a scene from the addressables

the bundle itself is loaded successfully, but then it can't find the scene in the bundle and can't load it

the scene name and the key name in the bundle are the same

this problem occurs when many different bundles are loaded during loading, if you try to load the scene in the game through the debug menu in the same way, it finds it in the bundle

we tried to set a delay before calling LoadSceneAsync but it didn't help

Scene 'Assets/Game/Scene/Scenes/Hotel_03.unity' couldn't be loaded because it has not been added to the build settings or the AssetBundle has not been loaded.
To add a scene to the build settings use the menu File->Build Settings...

[warm talon]

I reproduce this in unity editor

[onyx bear]

What’s the correct way of freeing up memory? I’m using the Release() method but the memory only goes down if I use Resources.UnloadUnusedAssets(), which always causes a stutter.

Any info about this would help me a ton!!

[gilded quartz]

Would a question about localization package make sense here?
I am trying to change the "String reference" of "Localize String Events" through code, like this :
public LocalizedString Title {
set {
this.titleTextUpdater.StringReference = value;
this.titleTextUpdater.RefreshString();
}
}

But when I do, the "Locolive String Event" seems to stop working. It stops reacting to me changing the game's language, and even dispalys a different default language than the rest of the game on startup!

Interface is English (correct language the game is in ATM. the Localized String Events there are not code-changed)

But the cards display the other language available : French. This is where I applied the code shown above

[gilded quartz]

OK... Made a few more tests and here are a few new things :

• If I make a build, things go smoothly there
• The amount of "texts displayed in the wrong language" can vary after changing scenes, etc

So this has to do with the way the editor accesses Adressables data that have not been compiled to adressables yet, I believe (direct asset access, I am no longer sure how it's called)

I think the editor can be setup to use the compiled adressables instead of doing that direct access. i am going to try that

Doing that actually solves my issue.

I'll just have to recompile my addressables every time.

But I'll leave all that stuff here, could still be useful info to someone or the unity team. There clearly are some issues with that "use asset database" mode. it does not replicate the behavior of adressables properly in this case

[dusk viper]

Anyone know how to build to a specific path ?
When i do that i have an error and i don't know why 😩
I try to build to D:/Assets

Error:

[earnest raptor]

Hello. I have 500 groups in addressable, each group has prefabs, of which there are 11 groups with an approximate number of prefabs of 100, each prefab has 30 child objects with the Sprite Renderer component. The remaining groups have about 20 prefabs with child objects (about 30 objects), which have animations, a sprite renderer. When assembling bundles, I consume more than 220 GB of RAM for the dependency calculator process. Please tell me how to optimize this? Maybe I'm doing something wrong. The project is growing and soon I will not be able to assemble bundles.

[graceful notch]

If all that is contained is the sprite render, you could use only one prefab, and have a script to load a different sprite.

[earnest raptor]

in 11 groups mostly only sprite renderer, but in the rest objects with sprite renderer and animations

[faint surge]

I just changed my SceneManager.LoadSceneAsync to Addressables.LoadSceneAsync. In editor there is no difference but in built Webgl app it is much slower and buggy. Any settings I need to do? I'm using List<SceneInstance> activeScenes to store the activeScenes.Add(await Addressables.LoadSceneAsync(AssetReference, LoadSceneMode.Additive)); for Addressables.UnloadSceneAsync(SceneInstance) later when scene changes

[inner verge]

Hey, I'm having alot of issues with addressable. Everything works fine in editor/player but when I build none of addressables is moved into build.

Forums told me to try going into addressable groups window and hit build there first, that succeeded the first time now throws an error every time even though nothing has been changed in the project or addressables.

Was told to try using the analyser in addressables but It runs for infinity stuck at importing assets.

The only thing in my addressable groups is terrain data as that's where most of my memory usage is in my game. Plan to add more to addressables later, but can't get this to work

[inner verge]

Screenshot of errors when i click new build inside addressable groups

[elder mulch]

I'm using LoadContentCatalogAsync and the RuntimeKey and GUID seem to become the addressable key. Is there any way to stop this?

[inner verge]

Got it figured out. Added a stack trace to the BuildScriptPackedMode file and found it was the ScriptableBuildPipeline.json file was nulled out and throwing an empty document exception in preferences.cs LoadSettings method. I copied this file from a blank project with addressables installed and built and it now works.

[prime edge]

Hi. I want to load assets from remote path (../[Environment]/Android if the environment of the app is set to beta) Can someone help me how to do that?

[inner verge]

I'm very new to addressables but should be relatively simple. Either change the value of the path at runtime based on a flag. Or you can use preprocessor tags like #if BETA to compile different pieces of code based on beta or production flags.

[solemn apex]

My remote Addressables was easily done for UnityCloud but im having trouble for Amazon AWS. I only changed the LoadPath to AWS URL but somehow it can't access the files or something

[slate timber]

Check my msgs

[slate timber]

To all of you guys who are having issues with addressable scene loading

There is no fix for it, and its been like that for almost a year

[slate timber]

I host it on AWS s3, and use cloudfront on top

[solemn apex]

thanks for this, I fixed mine as well, turns out AWS needed some more setting up

[slate timber]

if you use S3 alone the cost will be great

[slate timber]

did you manage to get around scene addressable loading?

or just downgraded?

[solemn apex]

yes. wait what exactly are people having problem about scenes?

[slate timber]

So imagine you distribute your game and the scene doesn't exist in your initial distribution. So the addressable system has to DL it. Once that happens, The scene is not added to the unity scene list and you cannot load it without restarting the game

[solemn apex]

ohyeah that was exactly my task back at work

yeah it loads

[slate timber]

check readme for error

[solemn apex]

ohhhhhh no wait

[slate timber]

It dont load the first time :\

I have to download the scene then exit the game

then restart the game

For the scene to load

[solemn apex]

ohhhh I get you

[slate timber]

Its only if you're using addressables >= 1.2.0

[solemn apex]

So if I update the cloud, will need to restart the app first before it gets the updated catalog?

[slate timber]

Updating wont be a issue, but the first time users running the game if they are downloading scenes, theyll have to restart the game after the scenes have finished downloading, otherwise the scenes wont be able to be set to active

[solemn apex]

what the heck

[slate timber]

yea ik

Ive been trying to get this issue looked at for 1 month now

Its been reported a year ago

[solemn apex]

hold on what does it look like when you test it?

let me also check what version im using cause I manage to load mine without any issues. Load a scene and set it to active

[slate timber]

so in my game i have this screen first, whihc downloads the assets including scenes. Then it switches scenes to one i downloaded after the dl finishes. When i finish downloading the scenes wont be switched cause i have not restarted

It will just be stuck

If i restart after downloading its fine

Gives this issue:

[slate timber]

try your game on a new PC or clear your game addressable download folder

And see if it switches scenes properly

Are you making scenes addressables?

this was my code for loading/downloading assets https://github.com/JayArrowz/AddressableSceneBug/blob/main/Assets/LoadingScreen.cs

[solemn apex]

that is... weird. now that I think of it I don't change scenes in mine. When I load a scene I just additively add the scene and set it as activescene.

[slate timber]

Ah i cant even do that, ive tried it

you basically want to delete this then run the game to test it

C:\Users\YOURUSERNAME\AppData\LocalLow\Unity\YOURPROJECTNAME

Thats your downloaded addressable files

[solemn apex]

uhuh this all looks good. Yeah I pretty much just use the latest version of Addressables. Altho I dont manually download dependencies... aren't dependencies automatically handled by AdressablesPackage?

[slate timber]

they are not. So you have to manually call Addressables.DownloadDependenciesAsync to download them (if you are preloading). Your code also changes to use AssetReference's and if you do not, the addressable will be included in your build

You dont need to call Addressables.DownloadDependenciesAsync but then the download will happen once you need the object

Which isn't that nice cause users have to wait

I use:
Addressables.DownloadDependenciesAsync(_label)

Where my label is something like "downloadOnStart"

And then i label my addressables which should be downloaded right when the user runs the game

[slate timber]

so lets say you have a scene which is not an addressable, but the scene references an addressable without using AssetReference, it will be included in the build which is not something people using remote addressables want

[solemn apex]

ohhhhhhhhhh damn now that is something

I just learned addressables this week tbh. Doing them remote

I was thinking about how dependencies go once you reference remote asset bundles will they be included in the build

[slate timber]

So imagine this script:

public class AScript : MonoBehaviour {
   [SerializeField]
   private GameObject _gameObject;
}

Now regardless of this script being in an addressable or non addressable scene. If my _gameObject is a prefab which is an addressable. It will not ACT like an addressable because i use GameObject instead of AssetReference

[solemn apex]

I guess I didn't encounter that problem because in our use-case we basically just call the scene by addressables ONLY. Like calling a roblox map or smt

[solemn apex]

yeah that makes sense. So then unity includes the GameObject in the build... because of how you referenced it?

[slate timber]

yes

Addressable Instaniation has 2 steps

Downloading -> Instaniating

I do the download at the start of the application so the downloading phase is already done and its not loaded in memory until i need it, so instaniating is pretty quick and user isn't waiting around for downloading when in the actual game

[solemn apex]

yeah that makes sense

its sort of like preloading then kind of caching

[slate timber]

yea

i use reference counting for addressables to free up memory

[solemn apex]

I don't get it. Doesn't make sense why doing this to Scenes will cause it to not work

[slate timber]

bug in unity's code

[solemn apex]

So it's either we change to a lower version of Addressables or only use addressables in more simpler straight forward way

[slate timber]

ive been upset man

for ages

At this

[slate timber]

yea lower version of Addressables should work OR not use em at all

OR

dont include scenes in addressables

its not too much of an issue if your scene is small

[solemn apex]

What if you not reference addressable scenes but just call them by Tag so when building the scene it doesn't get included?

[slate timber]

But you'll still need to get the addressable system to download the scene, the problm the bug is when the scene is NOT included in the build and added dynamically

This is my scenes rn on my build, I only have the asset downloader in my build which downloads my KitsuMapOne and UIs

[solemn apex]

wait so

Loading addressable scenes in general doesn't work?

I wanna test this

[slate timber]

it does not

[slate timber]

** Downloading and then loading them without a game restart between the stages does not work

I submitted it just now to the report bug, nobody on forums or discord looks like they can help

@solemn apex Oh yea i forgot to mention

the bug isn't in the editor

So if you run it with the editor itll be fine 🤣

If you build the game, then run the exe it wont

[solemn apex]

Alright ill get back to you guys after a while its a little late. Also Find this really weird. Been using a macbook pro at work and used Unity Cloud and AWS to load our scenes. I don't even preload the scenes I load them when you pick the map. Like if you pick Level2 it will then just call Level2Tag -> LoadSceneAsync -> SetScene as active

no problems. Scene then has things like spline, scripts and baked occlusion working

[rain quartz]

Where is Analyze Tool in Unity 6? Also didn't find in docs

Addressables version 2.2.2

[eternal river]

Hi, is it possible to make a player able to choose to have English subtitles and Spanish audio using Unity's Localization package?

[fair cape]

I have this error most of the time when update a previous build. Do you know how to fix it?

[small sorrel]

Hello all, can i use aws s3 bucket to handle unity addressable? and preferably the s3 bucket is private / have some protection so it not publicly accessible. is that possible? and how can achieve that?

[sudden drift]

coincidentally also working on this for our project, I want to know too. right now just I just set it to public

[candid pelican]

@small sorrel @sudden drift I have read about it somewhere in the addressables documentation but can't seem to find it at the moment. This forum post has a solution for it. maybe give this a try
https://discussions.unity.com/t/how-to-add-access-token-to-ccd-request-to-private-bucket/900276/8

[small sorrel]

i see thank a lot this might be something i could try

[onyx wolf]

@candid pelican @small sorrel @sudden drift i am trying to test the load and unload prefabs on demand. right now i have one simple prefab with its mesh and shader. all of them are addressables checked. The prefab and its related resources are correctly loading and unloading from memory, but even after unloading something tagged Untracked taking a huge memory space. my main goal is to reduce memory usage after unloading. any solution, please?

[small sorrel]

even after unload? tbh im not sure since im also starting using addressable, so i cant help much. But maybe you can manually call garbage collector? im not sure its works tho.
Maybe other's expert in this topic can help you in that, im very sorry cant help much

[teal mortar]

do you have other stuff from the same asset bundle still loaded? iirc you'll see the bundle staying in memory until every asset from it is unloaded

[candid pelican]

see in the addressables event window if its reference still exists after the unloading

[candid pelican]

yes its reference count should be zero

[onyx wolf]

its reference count is zero

but something called untracked is taking space

[onyx wolf]

thanks anyway

[onyx wolf]

the addressable group contains only the stuffs i mentioned, don't know anyhting about the asset bundle...howto check it/

[candid pelican]

pls share ur loading script

[onyx wolf]

using UnityEngine;
using UnityEngine.AddressableAssets;
using UnityEngine.ResourceManagement.AsyncOperations;

public class PerformanceOnSizeTest : MonoBehaviour
{
    AsyncOperationHandle<GameObject> handle;
    public string prefabToInstantiateAddressableKey;
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Q))
        {
            handle = Addressables.InstantiateAsync(prefabToInstantiateAddressableKey);
        }

        if (Input.GetKeyDown(KeyCode.A))
        {
            Addressables.ReleaseInstance(handle);
            Resources.UnloadUnusedAssets();
        }
    }
}

pretty simple one

[sudden drift]

Untracked seems to be the memory unity reserve for later, but it actually not use anymore I think

ohhh. might be the memory from memory profiler...

the thing with untrack is, you don't really know where it come from. but I know some time openning memory snapshot also increase it

[onyx wolf]

can you suggest me how can i see memory usage properly for android build

[sudden drift]

Just normal workflow of development build + attach profiler.
Profiling prefab might be hard to look for depend on what's on the prefab & its dependency to other bundle though.

[onyx wolf]

should i use scenes then? trying to implement a huge world streaming

[sudden drift]

I mean, it's hard in that you have to know what u put in prefab and know where the memory cost will go, audio will be shown in audio section, texture in video memory, mesh in other place etc etc. I would do it with prefab first. managing multiple scene seems harder in your use case, for prefab you can just directly reference them. & put them into list nicely. and loading addressable scene have some implication which might be hard to reason about.

[balmy carbon]

Do Addressables not work in unity 6? I imported the package but cant use UnityEngine.AddressableAssets like if I never imported it

[teal mortar]

it works fine in 6, are you sure it's not missing from an assembly definition you're using or something like that?

[balmy carbon]

I dont know what its missing, in the editor it works fine, it only becomes problematic when I try to access it in code

I just installed it so I dont think its missing a definition unless the package manager did an oopsie, but it should do all that on its own, no?

[balmy carbon]

All it took to work was to restart unity, how I love this engine sometimes

[sharp shoal]

I am trying the "Fix" step for Check Bundle Dupe Dependencies analyze rule for around 19k duplicated assets in bundles. This always gets stuck at the importing assets step. I have let it run overnight for ~9 hours but still the process won't finish. I had to force quit and open unity. I do see that all the duplicate assets are now moved to a separate group.

To counter this behavior I wrote a custom rule similar to Check Bundle Dupe Dependencies but this time instead of processing all the bundles, I forced it to fix just one bundle with one duplicated asset. I still see the same behavior where unity is stuck on importing assets step which is very annoying... Has anyone else seen this behavior with Analyze Rules. Using unity 2021.3.42f1 and addressables version 1.21.20

[sharp shoal]

Apparently few assets which addressables system was trying to group contained [] in the asset name which in turn is used in it's address path. The system is not able to recover from this error.
I had to skip all the assets with [] in the name and run the Fix step for everything else.

I built addressables locally and noticed a strange update to the AddressableAssetSettings.asset file. The m_currentHash value is updated to 00000000000000000000000000000000 Has anyone seen this before?

[nimble plume]

But I'll leave all that stuff here,

[serene sphinx]

PROBLEM RESOLVED!!!

Hello, guys! I was wondering if I could get some help with a script. One of my team's coders (now on hiatus) recently converted some functions in our game's AssetFinder script to return an async Task<GameObject>. However, all the other functions that he hasn't touched are expected to recieve a standard GameObject. I'm not sure how to convert it to a normal GameObject, and I would appreciate some assistance, as I've never worked with Addressables or ASync.

NEW FUNCTION EXAMPLE:

    {
        string[] guids = AssetDatabase.FindAssets("t:Prefab");

        foreach (var guid in guids)
        {
            var path = AssetDatabase.GUIDToAssetPath(guid);
            var operation = Addressables.InstantiateAsync(path);
            GameObject go = await operation.Task;

            if (go != null && go.name.Equals(prefabName))
            {
                Collectable goCollectable = go.GetComponent<Collectable>();
                goCollectable.type = goCollectable.itemSO.type;
                goCollectable.icon = goCollectable.itemSO.icon;
                return go;
            }

            // Clean up if the prefab doesn't match
            Addressables.ReleaseInstance(go);
        }
        return null;
    }```

I need to take the result and turn it to a simple GameObject

[hexed shell]

This code is very suspicious; why would you be using editor-only code with addressables?

AssetDatabase only exists in the editor, this code would not be able to be built with the game

[serene sphinx]

Not sure, this was a script written by another developer. However, xEvilReeperx helped me reach an alternate solution in #archived-code-general. Thank you for your expressed interest, though! I really appreciate it! 😄

[sturdy valley]

Hi guys. I have only half a question about addressable. I've been looking for an answer to the question about changing scenes for a couple of days. I've seen the practice of using an empty scene between unloading one scene and loading another. But no one can explain why this is necessary. And at the same time, everyone claims that when using addressables scenes, this is not necessary.
And the next problem is that I want to build the architecture of the game on one base scene where to store all the common things and the additive scenes that will be loaded into the base and unloaded. As I understand it, in this case, an empty scene will not work for me at all.
Please explain this problem with loading scenes and how best to do it for my architecture variant.

[onyx wolf]

can anyone please explain me the Bundle Mode in addressables? i can't understand it properly even after reading the documents

[floral current]

Hi! I was testing "Addressables.GetDownloadSizeAsync(key)" and there was something i'm confuse about in my testing. This method actually get whole size of my addressable asset instead of an individual. I'm showing a debug log on each of the key to get its download size but it keep stating the same value. To my surprise when I initiate download, It also download the same amount of size.

My question is, does that method return the full size of my addressable instead of individual (by key)?

[floral current]

Got the answer for this. Its actually because the bundle mode in group setting for the addressable was set to "pack together"

[orchid mountain]

I’m trying to wrap my head around something that should be incredibly straight forward: have multiple Addressables.LoadAssetAsync() calls simultaneously on different game objects that each need to load their own respective textures. There’s no overlap between these calls, yet I’m always hit with Exception of type ‘UnityEngine.AddressableAssets.InvalidKeyException’ was thrown. No MergeMode is set to merge the multiple keys requested” I tried awaiting Addressables.InitializeAsync() first to ensure that this isn’t the issue, to no avail. Any pointers?

[teal mortar]

are you sure it's the fact that you're making multiple calls that's causing the problem? do these requests work on their own?

[orchid mountain]

Yep, they work on their own, or if I spread them out in time

[teal mortar]

🤔

hmm are these remote or local assets, and are they from different bundles or the same bundle?

[orchid mountain]

Local, different groups (and therefor bundles I imagine)

[teal mortar]

can you share any code?

that InvalidKeyException can sometimes be misleading, it gets thrown for various reasons, but i guess you should only need to set a merge mode while loading multiple keys in one call or if one key resolves to multiple locations for some reason

[orchid mountain]

Well, going through it again and using Addressables.LoadAssetsAsync<Texture2D>(..., Addressables.MergeMode.Union); it actually ended up working. I'm not sure where it went wrong before - I think it it might have also thrown a very similar error due to a texture missing, and I glossed over it thinking it was the same error

[honest halo]

This controls if all the assets in a group go into 1 AssetBundle, or many. "Pack together" will result in 2 asset bundles (1 for all assets, 1 for scenes if any)
The others will cause many smaller bundles to be made instead. Can help with download size or loading.

[honest halo]

I have no issues changing scenes with addressables. We primarily use additive scene loading always and I usually load the new scene and unload + release the other at the same time (i await both operations via UniTask).
fyi additive scene loading can cause problems with baked light so you need to make lightprobes recalculate after loading is done.

[novel aurora]

Good day everyone. I am quite new to the addressable term in cases of remote collections. I rather have a general question. are addressables also capable of delivering content like assetbundles with the whole LoadAsset() pipeline across different apps or are they bound to a specific app and/or version of it?

[finite basalt]

for the love of gawd, i don't why keep getting this at the addressables module while profling, is it adding the same build layout over and over or something?

[rigid kernel]

Check which key is duplicate and removed that

I think nothing complex

[tiny swan]

Did anything change with addressables in unity 6? Having an issue that didn't happen in an older 2023 version of unity where every single addressible fails to load in builds (but load fine in editor)

First one that errors is:```
Unable to open archive file: 5a3bf240d84f9364a8a6616e6c5e36cb/defaultlocalgroup_assets_all_4db2a28a305d8173b91be6d70ef75575.bundle

[tiny swan]

Set the editor to use the archive too, cleaned and rebuild (had to restart unity because the addressables failed with no meaningful error first though?), and getting this error:
Unable to open archive file: 5a3bf240d84f9364a8a6616e6c5e36cb/defaultlocalgroup_assets_all_3d2c948d167cbc5da585467b1e7606c2.bundle

But looking at the addressable report I can clearly see that it exists:

[tiny swan]

Oh, wow, the code for addressables are a mess

Why does it call GetResourceProvider a dozen times on the same locator

[unreal delta]

I am trying the addressable tutorial.
What I want to do, is to not have the "Gamma" group in the default profile. So the load asynch of the sprite underneath it will fail.
How can I have that group not be part of one profie but part of a different profile?

[unreal delta]

Ok, I think I learned how to properly use addressable, and I can now choose to not include an addressable based on profile.
I had to write a little custom addressable build script, but other than that, it's pretty simple

[queen ridge]

Hi, I'm struggling a little bit to get addressables working for the Meta Quest. They have some documentation on how to add Required Asset Files (https://developers.meta.com/horizon/documentation/unity/ps-assets/#required-asset-files). The way I read it here, the asset files will be uploaded to the /sdcard/Android/obb/[package-name] folder. Does that mean, on my addressable groups, I should set that as the load path? I've tried it, and its struggling to find anything.

Additionally, if I wanted to test it locally, would I be able to adb push my files to that directory?
Thanks for the help!

This is in 1.22 btw

[fickle rune]

can we convert a game object to assetreferencegameobject through code.

[teal mortar]

yes, you can get the prefab's GUID with something like AssetDatabase.GUIDFromAssetPath or AssetDatabase.TryGetGUIDAndLocalFileIdentifier then pass it into the AssetReferenceGameObject constructor

[fickle rune]

Like how simonp.
If I have
AssetReferenceGameObject game;
Game object g;
Void Start()
{
game =g;
}
Like this I am trying to do

[low halo]

Is g an instance, or the prefab itself?

[fickle rune]

g is prefab.

[teal mortar]

take a look at the AssetDatabase methods i mentioned, a GUID is what you need to create a new AssetReference

[fickle rune]

I made it simonp.

[frigid stag]

You need to load the asset with addressables.

In your case, it might be a good idea to use InstantiateAsync.
https://docs.unity3d.com/Packages/com.unity.addressables@1.14/manual/InstantiateAsync.html

What you are doing wont work in a build given that you are using AssetDatabase which is Editor code.

Oh, I think I misunderstood, you want to convert a gameobject to an asset reference. Are you really sure you want to make that ?

[buoyant scroll]

Anyone? :/

[fickle rune]

I already did that.

[frigid stag]

As long as you understand that AssetDatabase wont work in a build.

[fickle rune]

I am importing prefab from Google drive and then converting it to addressable.

[low fractal]

Heyho 👋🏻 I am currently planning how to build my game world, it consists of many small islands that I would like to make all on a separate terrain and place each of these terrains in a separate scene. if you now travel between the islands with a boat I would like to load the scene with an island as addressable additive in or out depending on. How does it behave in unity 6 with lightmaps, can I dynamically load a scene with its baked lightmaps, AO and Adaptive Probe Volumes (APV) in and out in a main scene or can the light information not be loaded dynamically from an addressable?

[next inlet]

Did they get rid of the Editor Hosting service in Unity 6/Addressables package 2.2.2? I can't find it in Window/Asset Management/Addressables/Hosting

I'm guessing it's just a bug but want to be sure

[next inlet]

I also checked Tools > Window and it's not there either

seems like a strange move to remove this functionality, as it was super useful

[frigid stag]

As far as I know, you can only have 1 lighting setup active at the same time. You can set which one by setting the scene you want as active.

That being said, I suggest that you instead completely unload/load stuff instead. Obviously, if you do not see or have interaction with other scene.

[next inlet]

I have experience with this prior to Unity 6. What @frigid stag said used to be correct, however in some version of Unity (I can't remember which) they changed this to make streaming scenes with lightmap data possible. The easiest way to do this is to just open all of your scenes in the editor and perform the bake, with your main scene (which will be loaded at all times in your game) set as the Active Scene.

If you game world is massive and loading all scenes into the editor at once is not possible, another workflow is possible, however it's very tricky. I can describe the way to go about it but would rather not unless you absolutely cannot use the other method.

The above should work for lgihtmaps (which should include AO), Reflection Probes, and possibly regular Light Probes (not positive on this). I have not worked with APV's so can't comment on that. I know before it was not possible to use them with streaming scenes, however I'm not sure if they have changed things in Unity 6 to allow it.

[frigid stag]

Doing so would result in a 1 single bake data does not it ? Meaning that if you need different settings it would not work. (Ambient Color by example)

[next inlet]

Yes, sorry, what you said was technically correct. Only one lighting setup can be used unless you manually change the Active Scene (or there may be a way to change it via code without switching the Active Scene? I cannot remember now). However the user did not mention this, only whether it was possible to load lightmap data from different scenes additively, which is indeed possible and relatively easy to do assuming all of the scenes use the same lighting settings.

[low fractal]

Hey, thank you both for your answers. ( @frigid stag @next inlet )
That sounds promising in theory. I currently use Microverse to be able to edit several terrains at the same time, fortunately this also works across scenes, e.g. if you have a main scene and then you have one scene per terrain that is added additively in the editor. I'm going to try this out by performing a bake of the main scene while the additive scenes per terrain are loaded in the editor in the main scene. In general the light settings should not change per terrain, it is an island world similar to zelda windwaker, a simple grid of 6x6 terrains and on each terrain an island is displayed. They are all in the same ocean and have the same sun and therefore the same light properties I think.

[next inlet]

A quick update in case anyone comes here wondering the same thing. A Unity staff member confirmed that they removed the Editor Hosting window/service. Too bad, but I guess that's life!

[ivory crane]

hey im using unity 6 and im also trying to use CCD/Addressables for the first time. I installed both of those packages in my project as well and configured CCD to have my prodBucket selected as the remote thing. in the production environment i made a bucked named "prodBucket" and i uploaded and promoted a file named "race_unknown.png".
heres my code:
https://pastebin.com/AA2ApUcu
Unity throws 2 errors saying it cant find the location for "race_unknown.png"

[iron tundra]

Anyone looked at a way to use addressables with strongly-typed keys (without using AssetReferences) ?

[teal mortar]

why not AssetReferences? that's the default way to do strongly typed keys so it'd help to know what's wrong with them for your use case

[frozen quiver]

For synchronously loading, say, 100 keys, is one call of LoadAssetsAsync() with MergeMode.Union faster than 100 calls to LoadAssetAsync()?

After writing a performance testing comparing the two, and the one call of LoadAssetsAsync() is actually slower!
Batched: median 19.36ms
Non-batched: median 12.46ms

I would have thought that it would be faster since all of the I/O calls would be executed a lot earlier

Does anyone have any thoughts?

[frigid stag]

Not sure how much you can trust those tests of yours. I/O is can be pretty volatile.

Also, you could probably look what is happening behind the scene. There is a high chance that MergeMode.Union actually results in 100 calls. Merge.Union is not necessary a "batch" function.

[frozen quiver]

I'm running unit tests through several runs with Unity's performance measuring package, are there more reliable ways of testing I/O calls?
I'm using Merge.Union to get the resulting asset of every key, which I assume means that there would be an I/O call for each asset. Are there alternatives to that?

The theory is that the I/O calls is the bottleneck when called sequentially rather than in all at once. My results would show that this isn't the case for LoadAssetsAsync(), right?

Update: yeah, just looking at the profiler, it seems to be serial, (async call, wait for completeion, async call, wait for completion, etc.)

Got a median frametime of 11.34ms for just calling LoadAssetAsync() for every key and completing them afterwards. Guess I'll just do that

[frigid stag]

I personally, do a multiple loadasset and then create a Addressables.ResourceManager.CreateGenericGroupOperation.

List<AsyncOperationHandle> loadOps = new List<AsyncOperationHandle>();
foreach (IResourceLocation location in handleLocation.Result)
{
    AsyncOperationHandle<UnityEngine.Object> handle = Addressables.LoadAssetAsync<UnityEngine.Object>(location);
    assets.Add(location, handle);
    loadOps.Add(handle);
}

AsyncOperationHandle<IList<AsyncOperationHandle>> asyncOperationHandle = Addressables.ResourceManager.CreateGenericGroupOperation(loadOps, true);
while (!asyncOperationHandle.IsDone)
{
    Progress = asyncOperationHandle.PercentComplete;
    yield return null;
}

From what I have seen, it was the fastest.

However, I had some issue with a particular asset on Switch (loading one by one was solving the issue). So I believe it might not be 100% stable to do this.

[frozen quiver]

Thanks I'll def check this out

[slate timber]

my addressables return null

var handle = Addressables.LoadAssetsAsync<GameObject>("Assets/Prefabs/Trees");

whats wrong?

invalid key exception

[novel aurora]

Where is the rest of the code. Are you actually awaiting it to be done?

And I am not sure, if you can use / inside that name. At least I would try to simplify it and test

[slate timber]

i want to load a FOLDER

it works with a LABEL

but i want an ADDRESS

is that not possible?

[novel aurora]

You are not understanding how addressables work. They are not based on your folder hierarchy but categorized by labels and groups. If you want to load them, you need to have the reference inside the package that gets build, not the folder structure your original prefab is lying

[slate timber]

can i not use this as parameter?

[novel aurora]

you want to read this to learn how to load them in a correct way: https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/LoadingAddressableAssets.html

[slate timber]

this works but i dont see why i have to cast

var handle = Addressables.LoadResourceLocationsAsync("Assets/Prefabs/Trees");
yield return handle;
GameObject[] treesPrefabs = handle.Result.Select(r => (GameObject)r.Data).ToArray();

When i load a folder via a label i dont have to cast & its faster & less code
Can i not do this with an asset path?

Addressables.LoadAssetsAsync<GameObject>("Assets/Prefabs/Trees");

[novel aurora]

An asset path is a path, with one or many assets in it. How should Unity know, what asset you are trying to load with "LoadAssetAsync"

[unreal delta]

I am confused about addressable... do I need to rebuild the addressable in order to have any change apply to prefabs? It makes sense, but that's a big disadvantage then just editing a prefab, and pressing play to immediately see the changes.

[teal mortar]

not unless you're using the "use existing bundles" mode

[eternal river]

How i can get an LocalizedAsset in a Specific Locale?
Right now im using AsyncOperationHandle<Texture> op = localizedTexture.LoadAssetAsync(); but that returns me back the asset in the default language

[timber smelt]

hi im new on unity i have installed the engine right now and i don't know how to fix this problem , i did what the error says but i already have all the system requirements so i dont understand where is the problem can someone help pls ?

[tiny swan]

I don't think that's addressables related

[spark robin]

Hi, i'm testing something out with addressables to figure out some stuff...

Addressables.LoadAsset<TextAsset>().Completed += (var res) => this.Result = res.result; // Loads an 100 mb Test TextAsset
Addressables.Release(this.Result) // Should unload TextAsset and free 100mb of memory space

I'm testing this code inside my Update loop using some if key down logic. It loads the asset successfully, also release works without error but 100mb memory space remains allocated, it never de-allocates it automatically unless i do Resources.UnloadUnusedAssets() which is defined as performance heavy operation in the documentation.

Should i call Resources.UnloadUnusedAssets() when i release anything ? Or is there any better way to do this ?

If I should not release an loaded asset please give me an better approach, i'm just seeking for the best practice

[peak kraken]

the asset bundle is only unloaded when all assets in the addressable's asset bundle are released

[tiny swan]

Where did analyze go?

The docs still says it should be there: https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/editor/tools/AnalyzeTool.html

i guess I have to download 2.3 somehow?

it's back now, but the localization rules are not there :|

[tiny swan]

oh that's just great :) :) :)

[naive harness]

so never been able to reproduce, but got crashlytics logs where code doing something like this will null ref on the get component

var go = await _itemPrefab.InstantiateAsync().Task;
var cmp = go.GetComponent<SomeComponent>();

even know the addressable is there

so anyone know a case where i would get a null back from that instead of just a exception if it was not there

[teal mortar]

yes, that's the normal behaviour, if you want to get an exception for an error, check the exception property on the operation handle

if you usually want exceptions to be thrown instead, it's fairly easy to write an extension method for the handle to wait and then throw if there was an exception

[naive harness]

no my comment why is it normal behavior in this case, like what causes it not to return something when i know there was a asset

like its for a asset i know always exists

also so does that mean the addressable operation handles never raise a exception when awaiting the task?

[teal mortar]

do you mean it's loading from a local bundle so there should be no chance of network errors etc? well whatever the cause i guess you want to log the exception so addressables can tell you itself what happened 🙂

[teal mortar]

yes, the Task property returns a task that always succeeds but can return null if there's an error

it's not great but that's how it works lol

[naive harness]

Yeah thanks for the info, made a experiment to test

Wish it was clearer in the docs since it really goes against assumptions anyone with C# experience would make

[teal mortar]

unity moves in mysterious ways

[hallow sail]

Also interested in this use case!

[balmy robin]

Hello, I want to know if I load many of same kind of assets, how addressable assets system handle its loading,

Let's say that I am going to load PrefabA

5 times immediately asynchronously, then it will load 5 instances or just 1

Thank you 🙂

[teal mortar]

no, it should load once and you'll get 5 handles to the same asset

[balmy robin]

Nice

Thank you 🙂

[balmy robin]

Hello, not sure that we should release instance like this, I am going to attach this component to the game object and let it release instance when it is being destroyed

using UnityEngine;
using UnityEngine.AddressableAssets;

    public class AssetReferenceReleaser : MonoBehaviour
    {
        private void OnDestroy()
        {
            Addressables.ReleaseInstance(gameObject);
        }
    }

Or just don't having this component?, will addressable asset release instance immediately without it?

[kind depot]

You're not meant to use the native Destroy functionality, you're meant to use Addressables.ReleaseInstance, and for unloading a scene, Addressables.UnloadSceneAsync.

[prime edge]

Hi, My game is having a pink shader problem when a scene is loaded after downloading from Unity Cloud Content Delivery. Can someone help me to figure it out?

[soft ledge]

Does anyone know how to disable revalidation on webgl? what are the conditions that trigger the game to revalidate the bundle?

[slate timber]

my addressables are not in build

I clicked Build>New BUild

As in i built the addressables

[full widget]

Is there a way to dynamically set addressable LoadPath variables at runtime? (in my case RemoteServerURL)

[teal mortar]

you can reference a static property in those urls, see the curly braces syntax in the ones above yours

[full widget]

thanks!

[next inlet]

Are you using the Local build/load path? If so follow the Local Build path to find the assets (it should be in a sub folder within the output build folder if I remember correctly). If you are using Remote build/load path, it usually outputs the assets to RootProjectFolder/ServerData. Then you need to upload the folder in ServerData to your server or wherever you are loading from.

[slate timber]

fixed it

[next inlet]

I wanted to post something I discovered recently about Addressables, which particularly effects Shaders and Shader Variant Collections. I could only find vague hints around the internet about my problem, and although the end result of my findings may fall under the "common practice" umbrella, I think this will provide some additional information and hopefully help others understand Addressables/Asset Bundles a bit better.

Effectively, what you should know is that when you build your Addressables, Unity will automatically pull in references to assets that the assets in your Addressable Groups depend on. This is common knowledge. You can avoid this, of course, by adding the dependencies to Addressable Groups; then, instead of pulling in these assets, the original assets will just reference the asset bundles that the dependencies are in. Again, common knowledge.

Something that is less clear (but may be obvious to some), is that when pulling in dependencies, Unity will not be smart about it by pulling in the dependencies once, then having other assets that use the dependencies reference whatever bundle the dependencies were first pulled into. Instead, all assets that rely on the dependencies will pull in the dependencies to their own asset bundle, resulting in multiple copies! Most likely it is necessary to do things this way in order to not slog down the build process, so we just need to live with it.

Regarding Shaders and Shader Variant Collections, when you add a Shader Variant Collection to an Addressable Group, but do not have the actual shaders referenced by that Collection in an Addressable Group, Unity will pull in the shaders automatically to the bundle that the Collection is in. That's great, right? WRONG!? Other assets that make use of the variants do not know about these pulled in shaders! So, Unity ends up pulling in the shaders to those assets' bundles as well.

_ _
All of these different copies of the shader turn into the multiple copies of the exact same variants, at least in RAM (and probably on the GPU as well), which can cause you to run out of memory FAST.

In conclusion, it's not enough to just add the Shader Variant Collections to an Addressable Group. You must always ensure that your shaders are also added! This advice is scattered around the internet, but it was still hard to find a clear cut answer. on how shaders and Shader Variant Collections should work with Addressables. So hopefully someone comes across this and will be left with no doubts.

[noble cedar]

is there anyone from Unity team is here?

[noble cedar]

I have posted a question on unity forum, is there anyone here that can help?
https://discussions.unity.com/t/trying-to-understand-how-asset-dependency-works/1568122

[frigid stag]

That is true for any assets though ? You need to explicitly add dependencies if you do not want to have duplicate over the same dependencies. If you have two mesh with the same texture, you need to flag the texture same if both mesh are addressed.

[frigid stag]

The documentation is right.

It seem your test is flawed. You actually need to address them and use the addressed asset.

[noble cedar]

“If you use the same asset both in a scene and the Resources folder, then Unity makes copies of the asset when building rather than sharing a single instance.”

I’m testing this case only, it shouldn’t be affected whether it has been addressed or not.

[frigid stag]

From experience, it is not the case. I have used the resource folder + built in scene for a considerably long time and never had any issue about such thing. Addressable might change this though.

[frigid stag]

My bad, it seem I was wrong from what I read. In case of the asset being place directly in the Resource folder, like you did, the scene would refer this particular asset instead of duplicating. However, every asset that is not in the resource folder and reference by both would be duplicated.

I usually only reference the ScriptableObject from the built in scene

[rancid marten]

Nice day, I'm not sure if this is the right place to ask. If not, please let me know.
Curently, I'm working with loading asset from other project via addressable strategy and facing some weird behavior. My setup:
Project A: Game portal, sure is contained all the codebase of other project
Project B: Minigame (most of this is asset and the game scene)

My 1st try flow:

• From project A, Download catalog of project B.
• Locate the scene of project B by using this var locations = locator.Locate(sceneName, typeof (SceneInstance), out var list); and use DownloadDependenciesAsyncto download the scene. At this point, I get error:
  UnityEngine.AddressableAssets.InvalidKeyException: Exception of type 'UnityEngine.AddressableAssets.InvalidKeyException' was thrown., Key=Assets/gameScenes/02_GameScene.unity, Type=System.Object

2nd try flow:

• Instead of downloading, i'm using LoadSceneAsync() to load the scene by it location, at this time, the scene is loaded success. BUT, some sprite are missing. I try many way to figure it out but have no clue.

Please help me:

1. Guide me how to download a scene and all it dependencies in the RIGHT way
2. Does any one facing the same missing sprite / asset reference problem, and if you know how to resolve or how to investigate please guide me.

Thanks in advance.

[solemn apex]

Are addressables finicky around API's? have been wrestling around addressables failing to build because of a line that uses an API I got online. The scripts involved aren't even a dependency or an addressable. Man im comfused.

I even tried emptying out the adressables and just put an empty GameObject there, still the API script is being called out when building the Addressables fail

[teal mortar]

are you sure it's not just a regular compile error? something that only compiles in editor maybe? addressables does a script build as part of the pipeline so if you have any problems like that they'll show up there

[molten dirge]

I want to make a prefab for a card of a cardgame which assigns the card art of a specific card once loaded into a scene. It's supposed get a card Id of a card in a deck from a Database and then assign an image from the project's assets with that name to the gameobject in the scene. I was told I could reference Assets using Addressables but what I found online about it didnt make it clear how to use addressables for what I want to achieve/ if it is even possible. Any advice on how to make this come true with addressables or not welcome, ty.

[teal mortar]

addressables is like a heavy duty replacement for Resources.Load and the asset bundle system, if you're not already familiar with it and just want to look up various assets at runtime by a string name it might be easier to start with that and consider addressables later if you need features like remote content or asset bundle loading

[molten dirge]

thats what I ended up going with now but I was told Resource.Load will affect the Performance quite a bit

[teal mortar]

it depends how frequently you're doing it, best to profile and see for yourself since it depends on your game

[molten dirge]

I see

[teal mortar]

addressables doesn't really affect the performance that much as far as i know, it's still got to load the assets one way or another, but it is async by default which makes a difference

[molten dirge]

well right now I'm using it to assign sprites from my assets to a new created card prefab

i'm making a card game and using it only in deckcreator right now

do you believe it will have a significant impact? @teal mortar

[teal mortar]

well most of the cost will be loading from disk so probably the first time you see each card, after that it should be cached

it depends how many cards there are really

[molten dirge]

well it will be more over time in the deck editor but there will be a max of 180 cards and an aproximate average of 110 - 140 cards loaded at once in an online lobby.

different cards that is

it will probably be like half of the average loaded at the same time

given most of the cards come in multiples

[shy panther]

hey everyone, so i'm very very new to adressables, and i'm having a hard time understanding how it works, so i want to use unity cloud content delivery, because i have a game published to users in the store and i want to send them updates every now and then, i don't want to publish to app store and google play store everytime we do a small ui change or i like to add seasnal themes, so i heard cloud delivery is made for that, and i configured everything with adressables, now here is the thing i have a build on my app on my phone and when i push the changes to release nothing happens, does adressables work that way?? when releasing and every build gets the change ??? please help i need to understand more

[next inlet]

Let's say I have 10 prefabs marked as addressable. These prefabs are in the same group but packed seperately. So far I have been using Addressables.LoadAssetAsync to load each one individually. I queue up multiple calls, which creates some conflict between background/secondary threads and the main thread as they fight over file operations and the Persistent Manager.

Are these issues alleviated when using Addressables.LoadAssetsAsync? I.e., if I combine all the resource locations for all 10 prefab assets and just use that method to make one call, will it eliminate the thread conflicts? Or does this method just break down the 10 resource locations into 10 separate loading operations? I guess I'm just wondering if this method offers better performance vs the single asset loading method. I will run some tests but wanted to see if anyone had experience with this before wasting the time to make/run the test.

[teal mortar]

if they're packed separately it's still got to load 10 separate bundle files from disk either way so i would imagine that would still be the slowest part, it might be slightly more efficient to load them all at once but i don't expect much difference

ymmv of course, profile it is the the only way to get the right answer!

i don't really know what you mean by the thread conflicts though, did you observe performance problems or something? most of the parts you interact with are happening on the main thread and multiple calls to LoadAssetAsync shouldn't cause problems

[dusky saffron]

The shader dependencies work the same as any dependencies. In order to share an asset between multiple parent assets, you need to explicitely make that shader an addressable asset (included in a group). The shader variant collection is basically only needed to include shader variants that Unity does not have direct knowledge of (for example, if you use keywords, or have UI shaders with implicit keywords like UNITY_UI_CLIP_RECT).

There are cases where shaders (or other assets) do not get duplicated, but it's by concidence and should not be trusted. When all groups containing a dependency to the target group implicitely containing the shader, the shader does not get duplicated as it can be guaranteed to be found in the target group. However, if you change the target group so that the shader is no longer there, then all groups referencing that shader will either include a duplicate of the shader OR they omit it if another group they depend on, has it. It's complicated, and unpredictable.

TL;DR: Use shader variant collection to include shader variants you use dynamically and for shader warmup. Put shaders explicitely to a group to ensure they don't get duplicated.

EDIT: The implicit inclusion I talked above actually works in bundle level, not group level. So if your group is split into multiple bundles, only if your referencing asset references somethiing in the shader bundle, there's no duplication. But not only that, some of the Addressables settings might prevent referencing even the implicit assets if you don't include GUID's for the groups/bundles...

[dusky saffron]

if you know you're going to load all 10 prefabs in one go, then I recommend bundling them together. Loading multiple prefabs in one go can be done with either using the asset keys, addresses or labels, and should work fine, but if they share a lot of resources like shaders and textures, there might be some inefficiencies doing it in 10 distinct operations

[next inlet]

Thanks. I created a test and preliminary results show that there is virtually no difference between the two methods when attempting to load the same number of assets.

I'm making one change and will re-test for thoroughness, but don't expect these results to change. It seems the batch load method is indeed just a convenience method and doesn't offer any significant optimizations.

[next inlet]

While this is nice in theory my tests show that increasing the bundle size increases the cost of several operations that negatively affect performance.

Which is too bad because yes, this is Unity's general guidance. Bundle stuff together that's loaded together. Unfortunately it just doesn't work in practice.

[dusky saffron]

this highly depends on how the references are laid out. For example, if you have 10 prefabs which each reference a bundle that has asset load mode set to "All Assets and Dependencies" then there's change that dependency is loaded and unloaded 10 times - if it was not loaded already

[next inlet]

"All assets and dependencies" which setting is this? Is this in Group Setting? I can't find it in the latest Addressables package.

[dusky saffron]

No, if you need to load 10 prefabs at the same time, it will be more perfomant to load them in single operation instead of 10. The fastest way is to have a scriptable object that contains list to the prefabs, and then you make the scriptable object addressable, include in the group with the prefabs. This will load all 10 prefabs in single go.

[dusky saffron]

I'm not at the latest version, but for me it's here in the group settings

[next inlet]

They must have removed this setting in the latest version, but I'm almost 100% confident only the individual dependencies from the bundle are loaded.

Also there is no chance that the dependencies are being unloaded and reloaded, as the tests loads all the Prefabs before unloading any of them, and the dependencies are stored in a separate bundle (and thus not duplicated).

[next inlet]

I don't doubt that it is more performant, however I am especially interested in just how much more performant it is, because switching to the single operation method will require a lot of work to overhaul my current system.

So far I'm not seeing a major difference to warrant that extra work, and it seems like the single operation just mimics the multiple operation method under the hood, at least for the most part.

[next inlet]

This is an interesting idea.

I guess the concept is now you are only triggering one load, and the Prefabs are loaded as dependencies of the scriptable asset?

I wonder though, are you still limited to a max number of Prefabs with this technique? Because once a certain limit is reached, won't the cost of integrating all of those Prefabs into main memory be too high?

[dusky saffron]

We're still in 1.22 and Asset Load Mode is there. Also it seems that 2.3 has it too (https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/ContentPackingAndLoadingSchema.html)

The issue I described is one where your asset references single/few items in bigger "load all bundle" (usually by accident), and if that reference is not kept, then that "load all bundle" is immediately unloaded, just to be loaded again by the next operation.

But again, this is a fringe case and essentially asset configuration problem. Example is that you have an main menu UI bundle which contains some sprites and you make it "load all" to load the whole UI in one go. You then accidentally reference that sprite in your vfx asset, creating an unexpected dependency to the UI bundle. If that main menu UI bundle was no longer loaded (in combat etc), then loading those vfx asset will cause the whole bundle to be loaded into memory, and then unloaded if the reference to is dropped.

[next inlet]

Hmm, maybe it's a bug that it's not showing in the inspector then. In any case, it's not a concern here, as I can view the reference counts in the Addressable Assets profiler module and see that only some assets in the bundle are loaded. But I appreciate the explanation.

[dusky saffron]

indeed. It's basically a "asset pipeline paradigm shift" that makes you restructure your code, and can be hassle to do after-the-fact. But just wanted to say that it's a real problem.

For example, in one of our games, we had 100 UI views/panels that were loaded previously by spawning a single UI prefab nested with those said views. Worked pretty good, but was a monolith and took some time to load. We then changed it to loading 100 separate prefabs, and even when contained in the same bundle, initially this lead to insane load time. The biggest reason was how the asset integration in the mobile player builds works, and we were able to make it faster by setting Application.backgroundLoadingPriority to high. But even with that, it was nowhere near the same as before. We then ended up splitting UI prefabs into bigger chunks that load multple views in one go

[next inlet]

What I mean is if you have some operation on the main thread, and other operations on the background loading thread or background jobs thread, Unity will lock certain data from one thread.

The other thread tries to lock this same data but has to wait until the first thread unlocks it. You will see Loading.LockPersistentManager or Semaphore.WaitForSignal when this occurs.

It is not a big deal if it stalls out a background thread, but if it stalls out the main thread then you are basically just wasting time, as there's no way to have Unity work on something else while it waits (at least AFAIK).

[next inlet]

I will process this (and anything else you add) and respond tomorrow. It's getting very late where I am! Haha.

But I very much appreciate your input and suggestions/ideas. Thanks for taking the time to add to this discussion!

[dusky saffron]

I think the issue here is exactly what I described in the other message. Application.backgroundLoadingPriority is by default Normal, which means that asset loading can only use 10ms of time per frame. If you do everything in one chunk that takes 1000ms, the stall is inevitable (can't do partial asset loads). But if you split loading into multiple operations of 10 (100ms each), then it will mean that there will be multiple integrations happening over longer period of time. Not sure how the scheduling actually works, but if your framerate is 30 FPS (33 ms spent on doing other stuff), then that same load operation would take (33ms + 100ms) * 10 = 1.3 sec. Split to even more fine grained loads, and it actually just makes it even worse.

[dusky saffron]

Good luck with your endeavours. Try to keep your sanity 😬

[subtle jacinth]

has anyone faced an issue simialr to this? i download these assets from an addressables bundle, and they have these flashes and flickering in the material

[subtle jacinth]

incase anyone faces this in the future, i fixed it by upgrading from Unity 2022.3.13 to Unity 2022.3.54

[peak kraken]

You appear quite knowledgeable about addressables, I am wondering if we could get a sanity check for our method.

We converted our project to use addressables, so now we have one huge group with thousands of addressables, packed separately. We also ran the duplicate asset isolation script so that generated a group of the duplicate dependencies... So 2 groups in total both packed separately
Do you foresee issues with this? Our load mode is Requested Asset and Dependencies

[frigid stag]

It's not a good idea to have everything pack separately. You add a considerable amount of overhead to the work addressable has to do.

Ideally, you would group base on their locality. (Whatever is present at the same moment.)

https://unity.com/blog/technology/tales-from-the-optimization-trenches-saving-memory-with-addressables

[buoyant scroll]

When i want to make addresables for Play Asset Delivery are these settings okay? Because well, not working at all in PAD > Build > Play Asset Delivery (in Editor yes using Use Asset Database as Play Mode Script).
Should I check Build Remote Catalog?

[peak kraken]

Thanks for the info, yeah, I've been aware of the large overhead for packing separately, right now it's just a choice for simplicity after converting our entire project to addressables and also needing small patch sizes, among some other reasons... but packing by locality is something I would want to consdirer

[novel aurora]

Did you build the addressables before building the application?

I still would try to clean build the addressables in the group view and clean build the application to be sure, its not a caching issue

Well, thats a whole nother story 😄 But yeh, if your pc is faulty, anything can happen. I wonder where you get the null errors from, that you mentioned

But what is giving you the null error? A script? a debug line?

So your addressables async result is null?

can you show the code you are using?

rather the script itself. But the other statement is not correct 😄 Its either null or not. There is no close to null 😄

AsyncOperationHandle<GameObject> loadAddressable = Addressables.InstantiateAsync(reference);

        await loadAddressable.Task;

        if (loadAddressable.Status == AsyncOperationStatus.Succeeded)
        {
            GameObject newObject = loadAddressable.Result;
        }

Be sure to use something like this to check for the status and await the task to complete. Maybe your editor is just faster in loading it

Please send it here, I do not accept DMs

I like how you ignore the whole !code mention for large code blocks 😄

Its just hard to read large code in discord 😄 thats why its good to paste it on one of those sides. all good 🙂

But from what I see, you are returning gameObject even if its null, so you just continue with a null object.

you never really wait for the task to complete

Yeh, was just reading the docs and the mention this example. but yield will just pause for one frame and continue, doesn it?

I rather would go with the callback or await approach

Ah right, its not the gameobject (the naming is confusing :D) its the asyncoperation.

and that Debug.Log of the Result is null in your logs on runtime, right?

What part gives the null error then?

So this line should check, if its null, right?
if (gameObject.Result ?? false)

but you are checking, is it null, if yes, return false into the if statement and pass that part

[buoyant scroll]

any humble soul?

[honest halo]

I recommend not using Task but use UniTask. Second to better test you should build addressable content for the platform your editor is, change the "playmode script" to use existing bundles and then play.

also ?? cannot be safely used with unity objects as it bypasses the comparison override that makes a destroyed object == null.

There was also a bug that made URP shaders not be included in addressable builds even if needed in some older 2022 versions

[honest halo]

Probably not the problem then, i experienced an issue where meshes using urp shaders were not rendererd or were purple as all shader combos were stripped even if needed

im confused why you have this thing to load assets in such a way

i dont know how many assets you want to load but seems needless to have this complexity on top of AssetReference. I have never needed to do this and i work mostly on mobile.

why dont you test in editor with built bundles and debug to see the loaded result from the async op?

didnt know if that was asset database or real bundles

Build your bundles in editor (change to the platform that matches your pc), make sure it builds without any errors then change "Play mode script" to "Use existing bundles" so the editor actually tries to use those asset bundles and see what happens. Asset database mode wont let you find such problems.
[For me here, remaining on android will result in broken materials as it will try to use android shaders on windows]

I have never had simulate groups work so i dont use it

this is unity 2022 so perhaps they removed it 😆

but having it load real bundles lets you find whats wrong better as it will use the built local bundles and download remote ones too.
you can also use the profiler to see what addressable stuff is loaded/has references still.

[honest halo]

Oh if you are releasing the asset it will unload it if it then has 0 references

The docs are clear how this will break stuff if it's actually being used still.

[next inlet]

Sorry for the delay in responding; I've been busy the last few days 😅 .

I think if it were purely a matter of the time it takes to load the assets, putting everything in one giant prefab/asset bundle and using a backgroundLoadingPriority of High would make sense; the issue is that we are doing runtime loading/unloading while the player is playing the game. Thus, while it's crucial to make the load times as fast as possible so that the World is not just sluggishly loading in/out assets, it's also necessary that the loading/unloading does not cause frame stuttering.

So unfortunately, for our game which is on mobile, using anything higher than Below Normal is just not possible (maybe Normal can be achieved by optimizing other 3rd party scripts).

Right now there seems to be no other choice but to split the prefabs up into multiple smaller prefabs/Asset Bundles, although I am intrigued by your idea with the Scriptable Assets. However, I do wonder if such a design would not lead to larger Asset Bundle file read times, which is a big issue for keeping gameplay smooth while loading asset bundles in the background. Have you used this design to load assets in/out while the player is playing the game, or only while loading screens are displayed?

[dusky saffron]

Ah, right. In that case loading the assets the way you were doing is fine, but you should check out the asset load timing using the profiler from a build.

We had the problem that the load time increased for the exact reason that Unity loaded the assets as smoothly as possible... During a static loading screen 😅

[next inlet]

Yeah, it's a necessary evil that this strategy does slow the overall loading times, even in some situations where the performance is not critical (at the beginning of the game when a loading screen is used for example). However fortunately we can temporarily set the background loading priority to high in these situations to at least improve the time a bit.

[balmy robin]

do you guy having an issues with addressable assets loading with the changed codes rebuilt build?

i wish the old data can be used, if the codes changes have changes serialized fields, it still should work, for missing fields it can be ignored, but the problem i faced is it cannot be loaded

[plain terrace]

If you've changed how a class gets serialized, Unity will have no clue how to interpret the old data

[balmy robin]

if i don't change how any classes getting serialized, just change game logic then it will still working?, as i try sometime it is not 😦

[honest halo]

if the class has new fields or renamed fields perhaps FormallySerializedAs can help: https://docs.unity3d.com/6000.0/Documentation/ScriptReference/Serialization.FormerlySerializedAsAttribute.html

otherwise you will have to make a new game build and only use the new addressable data with that

[short dagger]

Hello! I intend on using addressables and wanted to make sure of something before I start with it.

It's my understanding that it's not necessary to mark dependencies of an addressable asset as addressable themselves as they'll be picked up by the loading process when I load the root asset (Assuming, those dependencies are only referenced by that one "root" asset)

For me, that'd mean that in the cases of scene, I can just mark the scene as addressable and not mark any of the prefabs, textures, etc... in it as addressable. I like that since it'd mean I can keep the addressables list neat and tidy with only root assets

[honest halo]

This is correct, dependencies are automatically "pulled" into the group that addressable asset is in.
if a dep is already set as an addressable though it wont and will just reference it. leaving it only to pull in deps can cause duplicates however but you can use the report to find and fix these (addressable reports get made after building content so you can see details about the bundles).

[balmy robin]

@honest halo i think the report still not convinience to use yet, don't it have any tools to do it automatically?

[honest halo]

Huh? If my response didn't make sense go read the official docs as it says the same

edit: the build report will state implicitly added dependencies, warn about duplicates due to this (dupes in many asset bundles) and has a tool to auto add these as addressable to fix the dupes. try it out and see

[balmy robin]

@honest halo No I am not intend to said that it is not make sense, I just looking for any better solution

Which tool?

Is it in the report dialog ?

[honest halo]

https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/AssetDependencies.html#asset-and-assetbundle-dependencies

report: https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/BuildLayoutReport.html

read up on how dependencies are managed. addressables uses asset bundles so it works the same

[short dagger]

Thanks for the answer!

[balmy robin]

I try to find the tool to auto add as addressable to fix the dupes but not found, I might have to try a newer version of addressables assets, (my project still on unity 2022)

[honest halo]

Try using this: https://docs.unity3d.com/Packages/com.unity.addressables@1.5/manual/AddressableAssetsAnalyze.html

The report should still list assets that got duplicated in that build so you can fix it manually (make it addressable)

[balmy robin]

Oh, I see, this is good

[blissful dirge]

Is it possible to limit an addressable group to only accept prefabs of a particular class?

And is it possible to determine load order of the prefabs?

[fast musk]

My studio has banned addressables since the last few projects using them all had issues. Biggest one being non-deterministic outputs which meant we would get different hashes depending on what PC builds them (and sometimes even getting different hashes from the same PC). We're talking about having to re-download 100s of MB of assets for a mobile game in some cases.

Does anyone know if Unity 6 addressed this in any way?

[blissful dirge]

When I try to build addressables I get the error: The type or namespace name 'SceneAsset' could not be found .. I am using it as a type in public async void LoadScene(SceneAsset sceneAsset) ... why would it not be able to use this?

Is it because of namespace UnityEditor?

[opaque valley]

Sceneasset is in the unityeditor namespace

[hoary rampart]

Our studio solved this by having dedicated build machines. OS version will affect the hash, so making sure all the machines were on the same version made a big difference

[fast musk]

Yeah, we're doing the same, we even purchased 2 new PCs with the exact same specs and OS just for addressables. Some of our projects are for big clients and tend to have hundreds of thousands of users, so the possibility of a PC breaking and causing everyone to download assets again due to different hashes being generated for the same content is 100% a deal breaker. I guess we're going to keep the addressable ban until that's addressed, I haven't seen any official response on this either. What a shame

[long dawn]

I'm trying to work on a game with my friend, we have an organization already and I am in it. When I open "add repository" i get this error (we are using version control through unity, not through Git) also is this the right place to ask?

[honest halo]

I think even the project name affects it, we used a separate job for building + uploading addressables and it would cause problems. The solution was to disable Crc check for local bundles.

[real venture]

We recently did a big investigation into the Unity Accelerator and ended up also investigating sources of indeterminism in project builds.

The addressable system is pretty robust and is fully deterministic as long as the inputs do not change. However, its determinism relies on the determinism of all the inputs and that's the problem that most people run into.

For almost all assets here is the list of things which are considered:

[unity version, host OS version, host machine cpu architecture, source asset version, source asset guid, target platform, compression/import settings] and maybe one or two other items to make the asset key touple in the internal unity asset database (this is also the same key that is used when using the Unity accelerator) the value is then the imported asset.

In order to reduce the chance of asset re-imports between machines and therefore reduce the chance of addressable indeterminism, the recommendation is to have exactly the same hardware for your build machines and use a Unity accelerator. You might also get good results if you load a copy of previously built addressables onto the build machine before building the latest content (although I am not 100% sure this is required/useful. someone else will need to advise you on that)

[honest halo]

We have 2 Mac minis as nodes via Jenkins and we have build jobs for projects. The prod build/addressables job should have been running from the same node but we always got this problem. I presume due to a different project instance for each job.

To be clear, the seperate addressable job was to build + upload remote ones and the catalog. This is why the local group hashes then caused an issue as they were then different (so disabling the crc check and having bundles be named after the group name only resolved this)

[blissful dirge]

@real ventureWhy is it done like this and not like md5sum or similar where it always the same?

[real venture]

md5 or sha calculations only tell you that the content in the source asset has changed. But source assets are not the only input parameter when generating an in-engine asset. Usually an asset is imported for a specific target platform, on a specific cpu architecture, with some specific import settings such as texture compression or format. So all of that needs to be captured to capture the intermediary asset correctly. (Plus the other factors that I mentioned earlier)

For example, if you're building for iOS and android the same texture file would be imported twice for the different texture formats involved, if the android project was built on an Intel Mac, an apple silicon Mac, and an intel windows machine then it would need to be imported 3 times and generate 3 separate intermediary assets into the Library folder.

At some basic level, there is an md5/sha256 style checksum check which is what determines if the source asset contents have changed, but we need to also represent the import settings and some parts of the environment (like cpu architecture)

[balmy robin]

Hello, I try to create a build script, I got "Timeout after 300 seconds while waiting async operations to finish" message when build addressable assets, how to fix it ?

[honest halo]

what is "build script", are you manually triggering an addressable assets build during your player build? You can enable it to be automatically done.

[dusty shuttle]

Hi world, I have lsome questions about cloud addressables
I have a very surface level understanding of them, so please correct me if I'm wrong about my approach / understanding

I have an asset from the asset store (specifically Naninovel) that uses sound files
I want to pull these sound files from the cloud (currently UGS) only when they are needed, preferrably through some code so I can control when to get them

Is it possible to... call some magic code to download the files and make them "appear" in the right place, and importantly only download when this code is called, independent of my asset that uses it?

[teal mortar]

i don't know naninovel but if a third-party asset doesn't support addressables itself it can be difficult to integrate it piece by piece, you can't have a normal reference to an asset stored in the cloud, it has to be an addressables asset reference object (or you need some other code somewhere to fetch it by its key)

and all of that has to be code that works asynchronously of course, since it might be downloading from the web

[dusty shuttle]

naninovel does have addressable support, I was just wondering if this "lazy" method was possible

[teal mortar]

if you can give it addressables references for the sound that should be fine then, the asset will presumably request them to be loaded at some point and then unity will download them as part of that

[dusty shuttle]

I see, and it will only get downloaded at the time of request right?

[teal mortar]

yeah, there are ways to preload things if you would rather have a loading screen up front

i don't do a whole lot with remote addressables personally but this sounds like a good use case for it

[dusty shuttle]

okay, thank you

[dark mica]

Is there a way to temporarily restore addressable items so that I can bake lightmaps?

[balmy robin]

I mean to use command lines (https://docs.unity3d.com/Manual/EditorCommandLineArguments.html) to execute build script, I can fix it by not using -quit command

[balmy robin]

How can I change device to rebuild addressable assets properly?

[balmy robin]

How can I change adressable loading file path remotely?

[honest halo]

you mean platform? If you want to build multiple platforms together I achieved this by doing 1 platform, writing to a file (as platform change reloads code state), changing platform, reading file to then trigger another addressable build.

[balmy robin]

Oh, sorry, I re-read and I think I have to explains it more, I mean to the situation which I have 2 PCs, then I build a game with PC 1 but later I move to PC 2 just to build addressable assets, but it is not able to download addressable assets files that were built by PC 2, something like that.

[honest halo]

You need to give more specific information and provide any errors or info...

[balmy robin]

It might be able to load remote catalog file, but it has monoscript cannot be loadded error message

That monoscript thing is included in build?

[honest halo]

Make sure in the addressable settings that "MonoScript Bundle Naming Prefix" is not disabled @balmy robin

[honest halo]

and if your remote addressables are built on another pc to the build itself there is a high chance that local bundle crc checks fail (as the build will download the latest catalog), check the logs for the build to see if bundles fail to load too

[balmy robin]

Monoscript is not disabled

Yep it is, then how can I avoid it?

[honest halo]

I disable crc checks for all my local groups to fix this issue as for a project i work on we had this problem. We had a seperate job to build addressables and upload and it.

if this isnt your problem plz explain it again better

[balmy robin]

I actually don't know how to build addressable assets properly, when I have to do new build? when to do update build?

I think I have to do new build when it have codes changes

And to make update build works properly, I must have addressables_content_state.bin in the project, so this one shouldn't be deleted, am I right?

I still worrying about broken files, unloadable assets, if it have any way to modify catalog files to change bundle files crc it will better, not sure that can we do it?

[uncut flame]

This is simple demo, 2 dlc scenes, with one UI button each, and one main menu scene with 2 buttons to load each dlc scene, so clicking just loads single scene and unloads previous (According to documentation at least), but ref count keeps climbing exceeding 3 scenes count, and used assets window shows correct behavior of one scene loaded at a time, why does scene ref count keep climbing, any ideas?

[honest halo]

did you release the old scene instance?

[uncut flame]

It does disappear in bottom left corner, but Im wondering why that scene count only increases

I do Addressables.LoadSceneAsync(scene, LoadSceneMode.Single, SceneReleaseMode.ReleaseSceneWhenSceneUnloaded);, so it should be released once unloaded

[honest halo]

huh didnt know it had this arg now but guess its not working as intended?

the old way works at least

[paper frigate]

int addressableAmount = bopsAddressables.Length;
List<Task> loadingTasks = new(addressableAmount);
float progressPerItem = ((0.98f - objectProgress) / addressableAmount);

foreach (string loadedObjectName in bopsAddressables)
{
    sb.Clear();
    sb.Append(buildablesAddress);
    sb.Append(loadedObjectName);
    sb.Append(".prefab");

    // Create a task for loading the addressable
    var handle = Addressables.LoadAssetAsync<GameObject>(sb.ToString());
    var task = handle.Task.ContinueWith(t =>
    {
        if (handle.Status == AsyncOperationStatus.Succeeded)
        {
            var result = handle.Result;

            catelogueItemsPool.Add(result);
            objectProgress += progressPerItem;
            return result;
        }
        else
        {
            Debug.LogError("Failed to load bops: " + handle.OperationException);
            Addressables.Release(handle);
            return null;
        }
    });

    loadingTasks.Add(task);
}

// Wait for all tasks to complete
await Task.WhenAll(loadingTasks);```

anyway to speed this up? I wanna load about 300 models. Any tips?

[honest halo]

its sometimes a bit faster to load many resource locations at once and then to use those to get the assets. Also better to use UniTask or Awaitable (2023+) instead of Task.

[paper frigate]

oh why is it better?

[honest halo]

It is probably because of it loading many object locations together. You can try loading all the assets together with their address too.

[fickle spade]

Pretty new to the addressables system and on a bit of a timeline, so I apologize if this is an obvious/common question:

I need to hold the player up in a loading screen until I can ensure they have the latest revision of addressables on remote. Presently I'm doing this by executing CheckCatalogForUpdates and then, on completion, running UpdateCatalogs if the list resulting from CheckCatalogForUpdates is > 0 in length. After that, if there were no updates (or when UpdateCatalogs completes, if there were) I run InitializeAsync.

Superficially this looks like it will work, but I'm finding it difficult to test. I have a temporary testing remote directory set up on another machine on a VPN, and I'm pointing my remote.loadpath there. Testing this in play mode (with the play mode script set to Existing Build), the script will spend a very long time on CheckCatalogForUpdates (about 21 seconds) but ultimately claim there are no updates to be had and advance to initialization. In a built client, the script hangs on CheckCatalogForUpdates infinitely and never advances.

I suspect I'm not getting through to LoadPath and the play mode version is simply timing out, but it doesn't say it is, and I haven't been able to narrow down the problem much. Any ideas?

I am open to testing remote from other places if there is an easier way to do it/one that would eliminate variables. The VPN solution is just what my team had set up ahead of time

As I understand I could simplify this whole operation by just waiting for InitializeAsync and letting it perform its own check (from the documentation it sounds like it does the same thing I do internally) but from my understanding what I've got here should work and it's strange to me that it doesn't.

[honest halo]

@fickle spade I think by default the catalog check doesn't have a time out set to make sure to set this.
Second i think the catalog is checked and updated on first use or manual Initialize() so i dont think you need to do it again.
https://docs.unity3d.com/Packages/com.unity.addressables@2.0/manual/InitializeAsync.html

[fickle spade]

I definitely don't, functionally speaking. The reason I'm doing it now is the team wants some affirmative confirmation if an update is taking place (versus just a check for one), but I might be able to talk them out of it.

[honest halo]

I guess if you update or download and update the catalog yourself at the very start that works but you should disable the auto download then

[fickle spade]

Yeah. I am going to try to refactor to use Initialize anyway, but can anyone confirm a timeout is what's happening here? I really should be able to resolve that directory but I'm not sure what else could be causing it. I'm going to try with initialize only when I get back from lunch.

Is there a way to retrieve the version hash CheckForUpdates is using internally? The crux of my situation is I need to be able to prove to QA that Unity is actually retrieving the correct version and updating as necessary, and to my knowledge Initialize doesn't give me a way to differentiate between addressables already being up to date and an update taking place.

Also im going to have to implement CheckForUpdates in a heartbeat anyway, so I do need to get it working.

[honest halo]

the time out is for the web request

ive had it freeze for ever before so its my best guess

[reef steeple]

Hello, this isnt addressables but its related to memory/loading.

I know when you have a public variable containing an asset on an active gameobject, that asset will be loaded into memory. But what happens if its the same asset multiple times?

Lets say I have 3 enemy spawner gameobjects that all contain the "Spider" prefab. They havent been spawned into the world, they're just being referenced for later use. What exactly is being loaded into memory at this time?

[uncut flame]

Update on my matter, the only way I could get rid of "the stairs" is by using this piece of code, I don't know why but handle expires at the time of scene unload so I can't release it then, and when releasing it here, scene gets broken, so it's still not a solution

It looks like it works only when using LoadSceneMode.Additive... why Unity why???

[honest halo]

It surely cant be hard for them to make it release correctly when the scene is unloaded right?

I think if you use InstantiateAsync() you have to release instance when you destroy it... WHY tf can this not be done for me 😐

[uncut flame]

There's literally an option to release handle, when scene is unloaded, but this simply doesn't hold true with single mode load, I found a workaround and I'll keep it until I am in a situation when there's need for a true single scene

Scene indicator got higher and higher, and I was unable to unload each bundle on console, so I am sure it holds it loaded

while Additive scene load makes it go to 2 max concurrently

[honest halo]

ive only really used additive scenes but i think single scene loading did work as expected. But i use UniTask so not sure if it matters

[uncut flame]

I usually use it to, but I did more testing today only to find nothing new

first two flat regions are additive loads, and last one is errored because you can't reuse AssetReference's operation

[honest halo]

I unload my additive scenes using SceneInstance and Addressables.UnloadSceneAsync() and it seems to work correctly.
I load scenes via await Addressables.LoadSceneAsync(sceneAddress, LoadSceneMode.Additive) meaning i never interact with the async operation objects.

[torn rivet]

Does anyone know if its possible to reference my game's addressables in an external project? I was thinking on how i could let mod developers reference an AddressableAsset inside an AssetReference.

I'm wondering if it could be possible to have individual Addresses taken from an existing catalog.json be selectable inside an Assetreference

i know you can load an external catalog, but is it possible to load said catalog in the editor and have it show up in the AssetReference's options?

[honest halo]

I dont remember how the data is saved in AssetReference but i have the feeling its a GUID because you can assign a non addressable asset and it half works in the UI. So if you can grab the guid and shove it into the asset reference it could work?
edit: its easy to set the asset in code in editor but may need to investigate setting other data manually

[torn rivet]

aye, i do know AssetReference saves its data at a runtime level with storing the GUID of the asset, alongside it's Type and sub-asset (if one is selected). While at editor level it keeps a direct reference to the asset itself. Sounds like i may need to modify the AssetReference drawer to see if it allows me to set the GUID field to an Address

[honest halo]

if the catalog has the GUID then that may be sufficient. sub object name is just that if using a spritesheet for example.

you can have groups not even include addresses so it must work

[torn rivet]

The catalog itself doesnt seem to have the guids... that or theyre all just one massive string

[honest halo]

hmm let me check one

[torn rivet]

there is this entry called keyDataString but thats not hexadecimal values so i know that cant be the guids

[honest halo]

looks to be base64 encoded atleast for the start but not sure how to fully parse it.

[torn rivet]

technically speaking AssetReference does just call LoadAssetAsync using the RuntimeKey property, which itself is just the GUID (or some extra fluff for the sub-asset)

[honest halo]

its in there but im not sure how to cleanly read this tbh

[torn rivet]

yeah it doesnt look simple to say the least

since LoadAssetAsync in AssetReference just uses the Addressables.LoadAssetAsync. Setting the GUID to be an address instead of an actual GUID might work

tbh idk if i had a fever dream but i swear i once say an Address inside an asset reference field... idk if that was in a specific version or if i'm just silly

[honest halo]

you can get the runtime key but its not stored

[torn rivet]

wym?

[honest halo]

I presume GUID is valid to load the asset if thats what its doing. the address you can get with a function but thats editor only

[torn rivet]

i see

[honest halo]

im not 100% but you can always test it out

[torn rivet]

i know the people who mod my game utilize a system called ThunderKit which itself saves the catalog from my game inside an editor project and that way they have a way to load the assets asynchronously in-editor. i'm unsure how it works exactly but since they have the catalog of the game there they could create a custom property drawer for AssetReference that lets them use a base-game's asset's address... OFC they need a copy of the game to be able to import the game's catalog in the first place so

[honest halo]

huh that is cool, i was hoping there was a way to parse a catalog in editor but seems not. not sure why they bother to use json when the main data is some binary format 😐

another amazing decision from unity

[torn rivet]

indeed, oh well. something something "we dont support modding"

a shame really, but i hope that approach works

[honest halo]

well you can load other catalogs at runtime and you basically have to have a separate project for this (unless you can have many catalogs in a project)
How they expect you to do it nicely is beyond me 😐
I've always wondered too why addressables doesn't integrate better, you have to have a non addressable scene as your initial scene for example.

[torn rivet]

its really funny how addressables is supposed to be the proper way but there's all these gotchas, which sucks

but yeah i reckon with some of that mod-developer brute-forcing they can get it to work

i've seen them do some crazy stuff

[honest halo]

I think because it uses asset bundles and they have the fatal flaw of not being able to reference into the game so addressables only work nice if EVERYTHING is in bundles.

if a bundle can depend on another which is not a guarantee then why cant it depend on assets in the proj already

[torn rivet]

yeah... oh well

lets hope this is fixed in unity 7 (unlikely)

[honest halo]

its doomed forever i think unless they decide to have some revision of asset bundles for newer unity versions that support such behaviour.

[uncut flame]

I believe this is due addressables being synctactic sugar over asset bundles which seem abandoned

[uncut flame]

I'd implement modding with NLua, some image import lib, gltf importer etc, since .bundles would require unity to be generated unless I am not aware of something

[honest halo]

Im glad they support runtime import/export for glb/gltf as its a great format with useful extensions.
I've had whole scenes with lights displayed via three.js using gltf 😄

[hot prawn]

Unity has a gltf importer

[honest halo]

yea we know?

[hot prawn]

ah

well good, we all know

[honest halo]

yea i was complimenting unitys package on supporting runtime use.

Hello,

We are currently working on a Unity project with multiple sub-projects, and we are attempting to integrate addressables from these sub-projects into our main project. We're encountering challenges and would greatly appreciate any guidance or insights.

Our Setup
A main Unity project.
Several sub-projects.
The goal is to create addressables in the sub-projects and then integrate them into the main project's addressable folder.

Attempts Made
Moved addressable bundles to the required location.
Merged the catalog.json files (adjusting internal IDs).
Created a new hash.
Unfortunately, none of these approaches have worked as expected.

Question
Is there a proper or recommended way to achieve this kind of integration?

Any advice or suggestions would be highly appreciated!

Thank you!

[novel aurora]

What do you mean by subprojects tho? How do you combine them or reuse assets from sub or main in the others?

[dusky lion]

for subproject we are using multiple git repo and we are connecting these sub repos into a single repo using git submodule concept.

[honest halo]

drag and drop an addressable group asset into the groups window and it will be added

[honest halo]

sub modules kinda suck id make them into unity packages which isnt hard, just make a package manifest file in the repo root then add the git url as a package.

[dusky lion]

Let me tell you in brief. I have 2 projects "Project 1" and "Project 2" and created addressable builds in both of them . SO i got "Addressable 1" and "Addressable 2", "Catalog.json 1" and "Catalog.json 2". Now i have put all addressables in one folder and merged "Catalog.json" files (Added "Internal id" of both together). Now i tried to run the build where i have all addressables in same build folder but I am getting "InvalidKeyException".

[honest halo]

you can add another catalog at runtime quite easily: https://docs.unity3d.com/Packages/com.unity.addressables@2.3/api/UnityEngine.AddressableAssets.Addressables.LoadContentCatalogAsync.html

the catalogues have binary data so i presume you did not "merge" it properly

[dusky lion]

The method you shared looks like it loads data from 1 catalog file only. But i want to merge 2 catalog files.

[honest halo]

it adds that catalogues data to the current data so you can do many in a row.
Its the only way i am aware of to do this with catalogs. Otherwise it would be easier to add the groups before building

[dusky lion]

Thank you. can you please suggest me, this link will be fruitful or not.
additionally, we are trying to build addressable local but this link says it will only work for remote
https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/MultiProject.html?

[honest halo]

This is because the default "local" path group asset bundles are embedded in the build and ofc another projects bundles cant be done this way.
Loading another catalog at runtime therefore only supports bundles that are located remotely or elsewhere (streaming assets?)

[dusky lion]

Let me clarify one thing. Our build runs entirely offline. So using "remote" addressables does not mean I have to upload them to a server?

[honest halo]

Yea i think if its a path to a file it will still load the bundle

[warped tree]

This is minor, but I was wondering if there is a way to apply the SearchContext attribute to an AssetReference?

I know there's the AssetReferenceUIRestriction and AssetReferenceUILabelRestriction attributes, but I don't want to restrict to labels.

With GameObjects I can tell Search to exclude Prefabs inside of models like so:
[SearchContext(query: "p: prefab:any -prefab:nonasset -prefab:model")]
But that attribute can't be applied to AssetReferences as far as I can tell.

https://docs.unity3d.com/Packages/com.unity.quicksearch@2.0/api/Unity.QuickSearch.SearchContext.html
https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/asset-reference-intro.html

[rapid void]

Hi, has anyone here worked with AssetBundle encryption (including Addressables) before? If so, would you be available for a chat? Preferably in German, as my English isn’t very good.

[honest halo]

Loading asset bundles manually will make decrypting them simple but ofc you need to then load from memory/ a stream. For addressables Im not fully sure but i think you would need a custom provider to implement decrpyting of bundles.
https://docs.unity3d.com/Packages/com.unity.addressables@2.3/api/UnityEngine.ResourceManagement.ResourceProviders.AssetBundleProvider.html

But if you are doing this to stop asset ripping its not worth it, it can only slow someone down. You cant fully prevent it.

[rapid void]

Okay ty, I've already found that path. I know I can't make it 100% secure. I just wanted to make it harder for users so that not everyone can do it.

So, is using the AssetBundleProvider the best approach for now? My concern is about the Catalog.json. Otherwise, I really have to build a completely custom loading system.

This is my current attempt: https://pastie.io/rzianf.cs, but it's still untested because I'm not entirely sure how it works with the catalog.json.

[torn rivet]

inside the editor, is it a common practice to load assets using Addressables.LoadAssetAsync() on a valid runtime key instead of accessing "editorAsset"?

[mellow root]

does anyone know the answer to this question? https://discussions.unity.com/t/addressable-cache-question/1580999/4. do local bundles need/benefit from cache? Need I would say no, but I do have weird behaviours right now. Also seems that enabling the cache doesn't really use the cache (android)

[honest halo]

this doesn't sound right... for local load stuff it shouldn't need to cache anything, its mainly for remote bundles 😐

[fickle spade]

Not 100% sure this is an addressables specific problem, but it seems to be. I've been troubleshooting for the past weekand am at the end of my rope, here:

The other day, the team updated the project I'm working on to Unity 6000.0.34 from 6000.0.23, and it broke addressables building for me. This is a problem only I have, but it affects both of my machines: Any attempt to build addressables results in an immediate failure with the error-
Internal build system error. read the full binlog without getting a BuildFinishedMessage, while the backend process is still running
This occurs whether I build the project normally or build addressables specifically from the Addressables Groups window. When it fails during a full project build, it fails during the portion that processes addressables.

I have been able to find very little on this subject, and I'm running out of ideas. I've:
-Reinstalled the editor
-Removed and Redownloaded the project
-Repeated the above, but on another hard drive
-Launched in administrator
-Completely removed Unity and Hub from my system, restarted, and started from scratch
-Regenerated library folders
-redownloaded packages
-Copied library folders from healthy versions of the project (residing on my laptop)
-disabling burst

This problem does not occur to other teammates, nor does it occur in other projects.

Has anyone seen this before? I'm stumped, and I've got a lot of people waiting on me.

[fickle spade]

Because of some intermittent success getting my laptop at to at least start building addressables (it doesn't have the RAM for the job and inevitably crashes) I have come to suspect the problem comes from an interaction with riderflow, but that is all I have been able to put together

[fickle spade]

The relevant parts of the editor log

[honest halo]

I think once before i had a very generic error like this. Check if a group is added more than once in the settings asset (via debug inspector view) and also check if a recent merge/commit duplicated an entry.

[torn rivet]

Something that just came up in my mind... I know that AssetReferenceT's RuntimeKey expects a GUID.

Currently i'm thinking about some mod development scenarios for people using my game, If an AssetReference<T> uses the GUIDS of my game to load the asset. What would happen in a scenario where a secondary catalog is loaded that has the same GUID?

Something along the lines of:

Main game project has asset A with its GUID.

Mod Developer adds a new catalog to the Addressables Catalog, which has asset B that ends up with the same GUID as A

How does addressables' AssetReference handles this discrepency?

[honest halo]

I think if you try to load a single asset it gets just one. If you try to load multiple it should return them all. Someone i work with was doing something with loading another catalog and had duplicate addresses.
How you will pick the correct one im not sure (perhaps by looking at the resource locations instead?)

[torn rivet]

I could theoretically make a helper class that lets you choose from which resource location to load from instead of letting addressables figure it out

thats nice

[fickle spade]

I think at this point it absolutely has to be the editor somehow. I got it working on my laptop (no idea what changed) copied the entire working project without any version control to my desktop, and opened it there. Build attempts hit the same problem

Not seeing any double-adds

[honest halo]

did you re clone the project?

oh derp i guess copying it did that

[fickle spade]

I've re-cloned the project a couple of times trying different hard drives etc

the weirdest part about this is that my laptop originally presented with the same error, but started compiling addressables properly after some background process finished

I was sure I had found the problem when it failed while riderflow was trying to work, but succeeded after it finished

but the more time I sink into this the more that's looking like happenstance

But yeah, in this case this is file-for-file the version on my laptop, just physically moved to my desktop and opened there

[honest halo]

then does it change if you remove riderflow?

[fickle spade]

I'm almost suspicious of some kind of .net problem

let me try

[honest halo]

unity should only be using mono included with the editor anyway unless something is using a system lib thats fucking it

[fickle spade]

part of what makes me think it is I had a very similar error from not having windows il2ccp installed awhile back

And at this point I've reinstalled Unity entirely several times

Starting to think it has to be system configuration somehow

[fickle spade]

strangely enough, I can't seem to get rid of it. The only reference I can find to JetBrains is the Rider Editor, which does not seem to be the parent for whatever process runs RiderFlow caching

In any case I don't think it could be the problem given my laptop doesn't seem to mind

[honest halo]

Perhaps you need to see what is at AddressableAssetSettings.cs:3042 yourself (you can find the file in package cache) @fickle spade

[fickle spade]

it's just the error handler line

frustratingly

[honest halo]

then next option is to enable generation of sln stuff for packages too and put a breakpoint

[mellow root]

"/// Note, that only AssetBundles loaded through UnityWebRequest are cached. If you want to purge the entire cache, use Caching.ClearCache instead."this settles it

[honest halo]

I guess de selecting that for the group will fix it?

[mellow root]

no I don't want to use cache, I just wanted to be sure that was the case. There might be cases where this might have benefits, not in my case as it increases the used disk space

[honest halo]

ive never needed to force unity web requests for local groups so i presume you will be fine

[mellow root]

indeed

[fickle spade]

Given up on trying to get main project addressables to build on my primary machine for the time being since I have them working on my laptop. Facing a new problem: I cannot get content updates to apply to built clients. They work fine in editor, and built clients don't report HTTP errors, but they will only ever use the first version they cache

Trying to test from localhost

any ideas?

[honest halo]

hosted the new catalog + hash?

[fickle spade]

Yeah. Got it into a position where the editor in play mode will fail to an HTTP error unless I have the new ones pasted onto the localhost server, so some part of that is working

and the editor responds as expected to content updates

[honest halo]

make sure you have a time out time set for the downloads and what platform is this?

[fickle spade]

but, while a built client will to load addressables if the server is empty when it is first launched, once it has loaded succesfully once it always loads from cache

StandaloneWindows64

No timeout set right now, although I've tried with one in the past. I'll put one back on

Should I have a custom download certificate handler?

[fickle spade]

Of note, the built client will report HTTP errors if remote is empty or has been replaced with a new build (as opposed to an update) only if "Use Bundle Cache" is disabled.

otherwise the built client behaves exactly as if it is using local assets

even if nothing ever resides on remote

With bundle cache disabled, it will HTTP error on a totally new addressables build, but will use the old addressables version if given an update

[fickle spade]

Could my method of testing be invalid somehow? I've been loading a texture2d into a rawimage and editing that texture2d between builds of addressables

Since the built client will 404 (presuming I have caching off) if I include nothing even after a successful load, that tells me the client must not be loading from a cache, but rather somehow retrieving the old file despite the presence of the new one and an updated catalog.

I think it must be a problem with my addressables_content_state.bin somehow

[fickle spade]

I am pretty sure I'm running into the problem described here:
https://discussions.unity.com/t/addressable-checkforcatalogupdates-does-not-work/1516925/16

Looks like a bug with 2.2.2 with a workaround in editing a conditional in source code? Not sure if I'm missing osmething; been a long day. In any case not sure how to go about it.

[rapid void]

Hey everyone, I’m trying again since I didn’t really get any helpful answers last time.

I have a project where the client always has different content. Depending on which server the client connects to, different mods (AssetBundles) are loaded. The main issue isn’t encryption but rather how to properly load these assets.

I’d still like to use Addressables, but how should I handle the Catalog.json (including the idea of using a CustomAssetBundleProvider), or are there better approaches?

The bundles can come from completely random users. Similar to GTA, anyone can add content and use it in-game. These bundles are always created externally from the main game. Later on, I might develop a separate tool to simplify the process for users.

I’d appreciate any tips or ideas!

[honest halo]

To add the content at runtime you can load in the catalogue at runtime. As long as the load paths are correct for where the bundles are it should work: https://docs.unity3d.com/Packages/com.unity.addressables@1.14/manual/LoadContentCatalogAsync.html

The next issue however is how to remove this later... I wonder if you can load the same one again later with different content and it will change 🤔

[rapid void]

Okay, thank you, I think I'll go ahead and build my own loading system. I can read the AssetBundles once at startup, get the list of what's inside them, store them in a dictionary in between, and then simply load and unload the stuff as needed. I think that's overall the best approach for my needs.

[honest halo]

That works but do make sure you store dependencies somewhere else so you load them in the correct order (deps first)

Why addressables doesn't support this better I don't know, dumb decisions once again

[rapid void]

Okay, thank you. I'll try messing around with it. If anyone else has smart ideas on how to solve this, feel free to share 🙂

[honest halo]

Id try to see what loading runtime catalogues does for you. I've not needed to remove them so it's been fine for us (we had a separate project for handling these different assets)

[rapid void]

Okay, I'll give it a try. Thanks.

[steady snow]

Hey, im having trouble with a UI element using addressables. I have an addressable scene with a button that I attached an onclick event to, but the onclick function i attached in the editor seems to disappear when i go into play mode and load the addressable scene. anyone having similar issues?

when I go into play mode from the scene with the button the onclick function i added (without loading the scene through addressables), the function stays attached

[steady snow]

ok, clearing cache from the groups menu then rebuilding fixed it, nvm

[novel aurora]

Are you setting addressables to run with a build package or runtime in editor?

[tawdry egret]

Anyone using 2022.3.41f1 or have experience this problem with loading addressables and the script doesn't get bundled? When I load it into my project, says that script it missing. If I manually copy that script over into my loading projects script folder, then it works. It'ls like the bundle is looking locally in the loading project instead of the .bundle file.

[wraith edge]

Are you trying to store actual scripts in bundles instead of references to scripts?

I don't believe this is supported since the usual consumer is a build which doesn't have the whole compiler toolchain shipped with it. It sounds like you have a project to project thing going on, in which case unitypackages might work better? Transferring them as text assets and doing some import processing to turn them into script files could also be an option.

[tawdry egret]

Well, I was testing out a widget loading style framework: a Portal project and a widget. Both two completely separate projects and the Portal dynamically loads the widget through addressable. All works except the scripts not being captured in the bundle. The whole point of addressable’s is that, to create a dynamic loading framework where projects can be kept smaller and modularized… but don’t include scripts? Hu?

[wraith edge]

Builds can certainly be kept smaller. I'm not sure this sort of project separation you seem to be talking about is a goal.
https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/index.html

[tawdry egret]

Thanks for the engagement. I find that surprising, I can see from the documentation in what you're saying.. Isn't it strange though that the pipeline would come that far...and then just leave out scripts? It's setting itself up to be an injectable framework, almost there, and then, naw, no scripts.

[honest halo]

The issue is its built heavily on asset bundles and these can just hold assets and not any compiled code. You would need to load a lib yourself at runtime to add extra components or other functionality

If you want components that work in 1 project but you build addressables in another then use a package to share these

[tawdry egret]

Which I could download and load at runtime, like addressables?

I thought packages were more static, in that it's only used in design time.

[wraith edge]

For editor or runtime use? Injecting compiled code on each platform Unity supports seems like a major task. I believe the goal was always just to make asset handling as convenient as possible.

[honest halo]

no the package is just for sharing code during editing and not for runtime loading

its funny how mod frameworks can do all of the things you want but unity provide no such way 😐

[tawdry egret]

I get it, I just come from a server backend development where building injectable frameworks is a nice way to build scalable applications that can load functionality at runtime and unload them, very powerful in pluggable frameworks. So when I saw addressable, that process is there.. but then the scripts were left out.

It's like I invite you over for a beautiful steak dinner, pick ya up in a limo, bring ya to my mansion, sit you down to eat...and no steak for you!

[wraith edge]

Well, they generally don't on the more trickier platforms.

[teal mortar]

i also probably don't want a game i'm playing to download and execute arbitrary native code from the internet 😨

[frigid stag]

Kinda tricky on platform that support only AOT. Without the fact that some platform simply refuse to accept code that is added at runtime even if you use dll or other means.

[plain terrace]

The mod framework exists partially because Unity doesn't offer a way :p

[mossy vale]

Hey, I did my research and frow what I understand it is impossible (in a built in way) to load external code (assemblies) for modding support in a IL2CPP game. Definetly not with AssetBundles and maybe with Addressables, but they can only load assemblies that are already in the project and not external in any way.

Is this true or is there also a hidden way to do this?

[wraith edge]

Above discussion is about the same topic.

[mossy vale]

event based scrippting it is then

[teal mortar]

yeah you can embed a scripting language or use visual scripting

[mossy vale]

I was talking about making a bunch of events and make the mod be a list of "if x then call event y"

[teal mortar]

sure i'm just saying there's some very existing solid options for doing that kind of thing

[mossy vale]

like a package for lua?

[honest halo]

you can integrate lua https://github.com/Semaeopus/Unity-Lua

[teal mortar]

lua will never go out of fashion 😎

[honest halo]

or research modding frameworks and see if you can do something to make it easier as some are quite powerful

[mossy vale]

in a quick search it doesnt look like these support IL2CPP

im guessing they use reflection

[honest halo]

what boneworks uses should support il2cpp 🍈

[coral iron]

does anyone know which addressable api does this compression format conversion ?

coz our project uses custom downloading script to download asset bundle, not sure if the format will be converted successfully

[sharp surge]

That would be the Caching API, I believe
https://docs.unity3d.com/ScriptReference/Caching.html

[frail lynx]

Hey, how do get the remoteLoadPath of my current profile in the code?
And how do I overwrite it?
🙏🏼

[honest halo]

//Get settings object
var settings = AddressableAssetSettingsDefaultObject.Settings;
var activeProfile = settings.profileSettings.GetProfileId(settings.activeProfileId);
// SetValue on profile and save asset after

You can do most stuff via AddressableAssetSettingsDefaultObject.Settings

if you want to check if a group uses a remote path now that sucks ass (how I did it before is by checking all schemas in a group until their build path id matches the remote id but you have to extract this yourself from the settings asset)

[frail lynx]

Im getting an empty string from it, but when I debugged and looked at the values in profile settings I couldn’t find the remoteLoadPath (where im getting the assets from)

[honest halo]

sorry what is "" ?

[frail lynx]

empty string

[honest halo]

haha no i mean what specifically has the value of empty string 😐

active profile id? the remote path?

[frail lynx]

oh activeProfile

[honest halo]

hopefully you can just check all profiles or hard code the ids

oh shit i forgot, you have to get the fucking profile id with its name

[frail lynx]

but i looked at one and didnt see any field that have something like this, and i only have 1 profile

[honest halo]

so you actually do settings.profileSettings.GetValueByName(profileId, valueName); and to get the id you do settings.profileSettings.GetProfileId("myProfile");

so active profile id is already usable to GetValueByName

my bad

i confused the ID of a profile vs its name

[frail lynx]

i can get see the profile but no url is there

[honest halo]

yea its stored elsewhere cus addressable bullshit

[frail lynx]

wait maybe i didnt make my self clear before haha,
I want to read the url of the remote load path, that I put on my addressable profile, so I can add "/platform" path to it on runtime, and get the correct bundle for each platform im using.

[honest halo]

Ah, you can modify a path at runtime by specifying a function to transform it.
But that's not a good way, you should use [] and {} to have the platform in the paths at build time

i can give an example when a proj opens...

[frail lynx]

what do you mean by [] and {} ?
im new to game dev
i thought i need different path for every platform since the game would run couple.

[honest halo]

in the url/paths in the addressable profiles, [] and {} let you "insert" variables.
[] gets resolved at build time, e.g. bundles/[BuildTarget] becomes bundles/Android

[frail lynx]

ohhh brilliant

[honest halo]

{} gets resolved at runtime so it can be a static property such as bundles/{Helper.path}
I use this for the platform to make it be lowercase cus unity in their great wisdom doesnt do this for build target 😐

public static string Platform
{
    get 
    {
        string platformName = "android";
    #if !UNITY_EDITOR && UNITY_ANDROID
        platformName = "android";
    #elif !UNITY_EDITOR && UNITY_IOS
        platformName = "ios";
    #endif
        return platformName;
    }
}

[frail lynx]

i have [] on the build path but the remote is url to unity CCD bucket

[honest halo]

Here are my remote paths for example:

the build path is to output em in a folder in the root of the project for a script to then upload to s3

[frail lynx]

is the AddressableHelper a custom class you made?

[honest halo]

yes

[frail lynx]

but how does unity know to read the values from there?

[honest halo]

cus its made to, its functionality they added.
https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/ProfileVariables.html#profile-variable-syntax

[frail lynx]

so just by creating this class in spesific path, unity will read from it?

[honest halo]

yea, read the doc page to understand better. If you had a class Foo with public static string Bar = "example.com" then you put {Foo.Bar}

Or [Foo.Bar] , again read doc page

[frail lynx]

yeah im familier

aright! thanks!

it's 1:55AM here so ill get to it tomorrow

[honest halo]

11:55 pm here 🇬🇧

[frail lynx]

oh, and does that mean i should keep path in env out of the git repo?

[honest halo]

er yea i would ignore where remote bundles are output to cus you dont need to keep em (post upload)

[frail lynx]

are you taking about the upload? i meant the path where i get the assets from

[honest halo]

what does "path in env" mean. use the default paths for the local groups

[frail lynx]

since i will need to write the path for my bucket in the AddressableHelper class it will be exposed
so it may be better to use enviorment variables

[honest halo]

well i guess an env var is fine for how you upload but its up to you. The build needs the remote url.

[frail lynx]

i dont mind it being in the built game, just not in the code in the repo

[honest halo]

something for you to decide i guess 🤷‍♂️

[frail lynx]

its not an issue usually in games?

i have fullstack background and there it's a no no

[honest halo]

anything in the client should be presumed to be readable by a user. The remote url has to be given to the client at some point so someone can read it.
This is why important services that need keys cant just be used in client (safely anyway)

i guess if you want the remote url to never be exposed then you would need a proxy server that is exposed blah blah

[frail lynx]

or secrets, but it's more about the urls in the repo rather than in the build
well ill go to sleep now, thanks a lot for the help!

[frail lynx]

Hey I have a few questions if you can 🙏

[honest halo]

Ask away

[frail lynx]

ok so first, im not sure i understand how to edit the remoteloadpath. i updated it on the addressable profile but when i ran the game i get an error (on purpose) and in it i see the old url

i tried to Build from addressable groups -> build -> new build -> default build script
but still it uses the old url

i had some other issues but its a followup haha

[honest halo]

Did you set this path on the groups properly? The path should update in the catalog to my knowledge if you rebuilt the content

[frail lynx]

Not sure I understand

I updated it on the profile, in the group im using that profile

[frail lynx]

i tried to also clear cash before, but it still wont use the new url

[honest halo]

what is play mode script set to? I can only presume its using an old catalog still hence the path not changing

[frail lynx]

i used existing build

[honest halo]

Perhaps the catalog being served was cached and its the old one still

[frail lynx]

i burned an entire day on this 🥲

[honest halo]

check what path your catalog is using too

[frail lynx]

i cant find the catalog anywhere in the files of my project

this is all i can see

none ^

[honest halo]

check the addressable settings. did you enable building a remote catalog there? check the path it uses too

[frail lynx]

i have just reseted everything related to addressables
ill check

its not enables atm. but tbh im not even sure whats happening, i deleted the ServerData folder which is the remove.buildpath and i can still load things...
i think im gonna give up on this... it's too unintuitive for me ):

nothing make sense to me here... things dont work when they should, and they do when they dont.. and cant find any good documentation for any of this

[honest halo]

the build path is where they are output, load path is where they get loaded from (local or some url)
If you have remote catalog enabled it will get that and use that if possible

[frail lynx]

should..

im still not even sure when the editor is using the local and when it uses the remote
atm. i have a remote.buildpath = ServerData/[BuildTarget] and this folder doesnt exist but still after im doing a build the editor manage to load'

[honest halo]

A reminder of what i use https://cdn.discordapp.com/attachments/844715993213173780/1339383208134971432/image.png?ex=67af2e11&is=67addc91&hm=b7db2a7eb632e9917554926ccddba493f0d52a5b306477f11329365bba39a17f&

[frail lynx]

yeah but like i said, i still dont understnd when it uses any of them (remote, local)

[honest halo]

Click an addressable group and check there...

[frail lynx]

in my case it seem to never use the remote values i guess

I know where it is, I updated it constantly, im saying its being ignored

maybe my english is not clear, ill try to explain again,
I updated the value Remote.LoadPath in the Addressable Profiles -> default (profile)
but even after i go to
Addressable Groups -> Build -> New Build it still not using the new value i put there

it seem like its using the local paths when i use the editor

ok i figured out its not using the remote paths when you are on the editor

[honest halo]

did you check this?

(i have an editor profile that loads remote stuff from the build path for easier testing)

[frail lynx]

oh let me see

ok so now it will ask for the remote path on the editor!
works

but i cant seem to load from unity CCD bucket correctly
i used this url:
https://b2f379ed-3701-4dd0-8f41-5f1fcf1d4c69.client-api.unity3dusercontent.com/client_api/v1/environments/production/buckets/4b5408e9-47bd-4381-9177-0269bdb95d32/release_by_badge/latest/entry_by_path/content/?path=/[BuildTarget]

and i got the StandaloneWindows64 at the end of the url successfully, but i still cant find/access the assets and getting 404

even though there are there

[honest halo]

i dont have any clue how the unity hosted stuff works, that surely cannot be the correct url to use...
What my work uses is s3

[frail lynx]

well, it works just fine if i dont include the [BuildTarget]

because i added the files to the root also

ok so i guess ill have to figure out how to access them correctly, and worst case just have different bucket for each platfrom (and different profile)

everytime i feel like i get whats going on it keep surprise me...
are you sure that i get the assets from the remote repo?
i think its getting it elsewhere

i just replaced the url with nonesense and did a new build and it still got the assets

[honest halo]

if the load path is say https://example.com/bundles it will load from there
the catalog matters though, its where the addresses and paths are stored

[frail lynx]

i dont understand

is it loading it from the url or caching it?

because the url right now is not real yet the game loads them correctly

the howww is in there... so how is it able to load the assets?

[honest halo]

show me the path its using for your remote catalog

[frail lynx]

for the remote catalog or in the remote catalog?

[honest halo]

in the inspector for addressable settings

[frail lynx]

this?

[honest halo]

set player version override to a value so your catalog names are consistent

[frail lynx]

done

ok its consistent now!

thanks a lot!

[honest halo]

It helps when you want to update an existing builds catalog and bundles later
otherwise it will give the catalog a new name and it wont work

but ofc remember if you want different game versions to use different bundles you need to change this version or change the path somehow

[frail lynx]

managed to load with the correct platform path 🥳

but if i want to build for WebGL, i cant really load it since im on windows.. is there a way around?

[honest halo]

if you change platforms in editor it will try to load em but shaders and some textures will be broken

[frail lynx]

i only have a gameobject with list of scriptable objects on it

i switched to web (before build)

and after i build its actually working now 😮

ill try to run it from browser

but i wonder if it will work.. because [TargetBuild] is determined on build time by UnityEditory bla bla application something, but it will show windows because thats the current platform no?

i cant check anything now because it takes 10 minutes to build for web 😶

damn Brotli Web.wasm... take ages..

its working!!!

[honest halo]

yay glad its good now

[frail lynx]

thanks a lot!!! i feel a little more confident now in addressables hahah

couldnt have done it without you 🙏 🙏 🙏

[honest halo]

i've battled with addressables a lot so glad i could help

[frail lynx]

oh but i have AudioClip in the scriptableobjects in the asset, and i cant play it on the editor now..
it means i must stay on windows build when i develop?

[honest halo]

yea cus bundles built for another platform are made to work on that platform only. ofc you dont need to use existing bundles always

the assets get processed for that platform (e.g. build the shader for android so it doesn't work on windows)

[frail lynx]

so ill develop on windows and when its time to release ill switch and build

[honest halo]

you can be on the webgl plat but change addressables back to "use asset database"

[frail lynx]

brilliant!

and one more question if you will my good sir, about the correct way to use the addressable

im making a small match-3 game and wanted to have the tile variants as addressables so i can update it on the fly, i created a scriptable object that hold the data of the tile (sprite, audioclip, color, and logic and vector list for the matching and poping logic)
and i wonderd how to wrap it for adressable

ATM i make a new prefab of game object with a script that gets SerializeField of List<MySO>

is it a good approach?

[honest halo]

er well ofc you can load the asset with the address or use AssetReference to not serialize a ref directly (and thus make a dependency)
I guess it depends how you want to be able to change this data later. If you use unity remote config for example an address there is easy to change any time

[frail lynx]

i dont think i understood half the terms 😅
i just have list of SO

so if i want to update the list i just add the new SO there and build and upload to the bucket

and in the game i set a reference for it on my gameManager

[SerializeField] private AssetReferenceGameObject tilesList;

[honest halo]

eh why not have the list on Gamemanager

why do you need a prefab to then have a list

[frail lynx]

because this prefab is the addressable

[honest halo]

its referenced directly by game manager... is game manager in an addressable scene/prefab?

[frail lynx]

you ask why not make a list of addresable references in the gameManager?

[honest halo]

The data in the "game build" and "addressables" cannot mix with direct references

[frail lynx]

im not sure i understand

why is it mixed here?

[honest halo]

If your start up scene is "Main" and Main has a ref to an asset, that asset is included in the game build (fully seperate from addressables)

If i put this asset also in addressables, its duplicated! Its in the addressable bundle AND in the game build

[frail lynx]

ohhh i think i undestand. well i thought that because i dragged it to the addressable group it excluded it from the build

and i never use it directly, i dragged the "prefab" to the game manager from the addressable group

[honest halo]

no. If you remove the field "Tiles List" and instead use AssetReference<GameObject> then its okay as this references the addressable indirectly

or doing Addressables.LoadAssetAsync<GameObject>("myAddress")

[frail lynx]

isnt this the same?

[honest halo]

HA you are right my mistake ignore me 😐

[frail lynx]

[SerializeField] private AssetReferenceGameObject tilesList;

private void Awake()
{
    tilesList.LoadAssetAsync().Completed += LoadAddressables;
}

private void LoadAddressables(AsyncOperationHandle<GameObject> handle)
{
    if (handle.Status == AsyncOperationStatus.Succeeded)
    {
        List<TileSO> tiles = handle.Result.GetComponent<AddressableTilesList>().TilesList;
        Initialize(tiles);
    }
    else
    {
        Debug.LogError($"Failed to load asset: {nameof(LoadAddressables)}");
    }
}```

[honest halo]

Then back to my original point, why not use 1 scriptable object to reference all the others instead of miss using a prefab?

you can also use tags to load many assets at once with the same tag (labels? i forget)

[frail lynx]

so creatre a new scriptable object that have a list of scriptable objects inside?

and i thought about labels but wasnt sure how to sync it all and call the Initialize(tiles); only after all the assets were loaded

im sure there are solutions i just didnt go deep into it, is it better to do it like that?

[honest halo]

up to you i guess. labels can be useful sometimes but dont bother if you dont really need to rn

[frail lynx]

atm i see 3 ways
gameobject (mine)
SO with list of TileSO
and seperatly (with label) and await with the Initialize(tiles);

[frail lynx]

I wanna learn the common practices 🙏

[honest halo]

https://docs.unity3d.com/Packages/com.unity.addressables@2.3/manual/Labels.html

ive used them in the past only to help pre ~~load ~~ download assets ahead of time for stuff

[frail lynx]

yeah, here its not to help the load, its just to enable dynamic updates

[honest halo]

then maybe change it to 1 so with the list and call it a day

[frail lynx]

is it better than gameobject with a list?

[honest halo]

yea it better fits what you want to do, reference a thing that holds a list

[unreal delta]

If a shadergraph reference a subgraph somewhere else, addressables do not know to find that reference?

I think it's even the material, it always takes the older material version somehow

[unreal delta]

The material isn't being updated in the addressables, no matter what. When I click it on run time, it doesn't ping the real source of the material.
