Have you tried running the tests here?

#

First thought is it might be worth looking in the 'top level settings' and seeing if you have build remote catalog enabled? It looks like it's trying to get the package locally.

# mild flax Have you tried running the tests here?

yes - that's what I'm talking about. After running those tests you get duplicate bundle dependencies, but it's hard to figure out what is actually causing the duplication. There are assets in there that I don't think are actually referenced by things in the bundle

Hi everyone.
I'm having an issue with Addressable.LoadSceneAsync in build.
The AsyncOperationHandle seems to be stuck at 45% while it works well in Editor PlayMode.
(for info, I'm running on Unity 2021.1.22 and Addressables 1.18)

#

does anyone have any idea why that happens ?

unique beacon
#

A little more in-depth :
the AsyncOperationHandle.Task seems to be stuck in WaitingForActivation status, thus preventing completion.
I've yet to figure out why the Task is not activated...

unique beacon
#

Found out by using WaitForCompletion that it is stuck on AssetBundleProvider.GetAssetBundle
More precisely on m_AssetBundle = (m_RequestOperation as AssetBundleCreateRequest).assetBundle; (l.305)

hello, new to addressables just instaled the package on my project but i can't find the name space

#

already tried updating visual studio

#

i already made some assets addressable so it's defiantly installed

unique beacon
#

@thorny bay Are you using vscode, or vs 20xx ?
Is that error showing in Unity console too ?

I had the same error on vscode at some point, omnisharp did not seem to get the symbols loading.

If you don't have that error in Unity console but have other issues for compilation, fix those and it should regenerate the project files with the symbols for vscode to work with.

thorny bay
#

I fixed it by deleting csharp files in the project

#

and then rebuilding the project in vstudio

thanks tho 🙂

Is there any way to set a field on an object created using AssetReference.InstantiateAsync before Start is called on it? In my tests, Start gets called before control is returned to the code calling InstantiateAsync

assets which you think are duplicated, mark them as addressables aswell

Hello Team Unity, we are using addressable in our game with voxel play. The issue is that if I add any asset as addressable it has dependency files with voxel play. If I try to add voxel play files as addressable it won't allow me to do because it's assets are located in resource folder and I can't move that out of resources folder it won't work. What would be the ideal solution for this issue?

Hi!
I'm Andrea, from Rortos (an italian game development studio).
We are working on a project using Asset Bundles.
We are having problem with Caching.ClearCahce() function. It returns false.
So we have tried to use GetAllCachePaths() to manually clear all caches.
Every single cache returns true except for one: scenes cache.
Why ClearCache always fail on cache which contains scene objects?
Have you ever seen this problem?

mild flax
#

I could be wrong but I think Caching.ClearCache returns false even when it succeeds? At least I think it seems to work reliably for us when it comes to actually clearing the cache.

odd junco
mild flax
odd junco
#

We are using Unity 2020.3.19f1 (LTS).
We are seeing this problem running in UnityEditor

mild flax
#

The main reason I can think of that it would fail to clear the cache is if it thought the assets were still in use. I guess that doesn't help much though.

odd junco
#

The problem seems to be related to cache size.
If cache is too small and you try to download something bigger, the ClearCache will fail.
I think it's a bug, don't know if it's an only editor bug

Is there a good way to share the same asset group between a client and server build that are different projects?

white sun
#

That's what I'm doing with a 3rd content project. No issues so far, just build the remote addressables, then load the generated catalog in your client/server projects

ionic shadow
#

Is there any easy (automated) way to find dependencies between a local group and remote group? (or simply- 2 different groups?)

I found out that having a reference (direct reference, not assetreference) in a local group to something that's marked as addressable in a remote group causes the remote group's bundle to be downloaded when loading the local asset 😵.
I found some of the dependencies by hand (looking at Bundle Layout Preview unfixable rule in Addressables Analyze), but apparently there's more things left that I must have missed...
I expected it to put asset duplicates in the local and remote groups in such cases, but nope 😐

Hello All

This is Pranoy. I am trying to add the audio files in my project to the Addressables group but I am unable to do so. This is because there is no option of selecting the addressable option in the audio import settings in Unity.

Can you please let us know, if we can use audio clips inside Addressables group or not? Or am I missing something?

Did you actually install the addressables package? Audio clips can be marked addressable and the option should be there.

Hello All. Im using Addressables 1.16.19 in my project with Unity 2020.1.17 and running into a weird issue. I use unity cloud build to generate my assets from a azure git repo for my app (live on android and ios) and then push those generated assets to an azure blob storage to update the assets in the app. This has been working great for over a year. I normally make changes, commit to the repo, then in cloud build do an update against the content_state.bin file for each build target.

Recently my azure team enabled Git-LFS and specifically targeted FBX files because the repo was getting too large to generate builds via azure. This obviously caused issues when I generated assets because the FBX files were no longer directly in the repo. My assets would still appear when placed or used in the app BUT without a model/mesh. When this was discovered I immediately removed all LFS stuff and recommited all the FBX files. However, doing an update to the addressables via the method above did not fix the issue.

So I grabbed an older content state.bin from version control pre-GitLFS and updated addressables against that and it fixed the issue - for Android. But grabbing the same comits content state bin from the iOS folder and updating iOS assets against that state bin did nothing. Notably a git compare between the current content_state.bin and the older version say they are the same anyways. But now even when I update current assets the changes do not seem to be taking effect after building assets.

Does anyone know what could be going on? Or if not does anyone know if there is a way to generate a brand new clean set of addressables for the current build player (ie - not generating a whole new build of the app, just the addressables) via cloud build?

tired blade
#

hi, uh it might be a dumb question.. but having the prefab (containing a mesh and material with texture) in the addressables should pack everything together, right?

With Addressables, can I store the Result from an AyncOperationHandle in a variable and pass the variable to the Release() method? Or do I have to pass the operation handle?

A addressable prefab I have is referencing a scriptable object. When creating an instance of this prefab (via LoadAssetAsync then GameObject.Instantiate) the reference to the scriptable object becomes a different reference than one on a component in the scene from the start, so equality comparisons don't work. Any ideas how to prevent this?

mild flax
uneven onyx
#

yeah - I managed to google correctly and found some forum posts about this too. I was hoping there would be a way to check equality via something "deeper" like what the addressable SO was created from, but it doesn't seem like that exists

#

option (3) is make sure there are no scene references to the SO, everything comes from the bundle, I think?

mild flax
#

option 3's valid yea 👍
fwiw I created asset partially to help with this problem (it's called BTagged) but you could create something similar if needs be. Basically you inherit from it instead of SO and it gives you a .hash that's unique per asset.

It means your Meshrenderer either has no material or the material is using an unsupported shader

#

Sort of wacky, but if you have one main character that is a constant throughout multiple levels or scenes, is it better to have the one character on dontdestroyonload, to keep him throughout the scenes, or a prefab of the character with the same stats?

Hey guys
I have a question about Asset Bundles, If I have two separate projects, one for creating DLC (A) and the other the main project (B). Can I create an Asset Bundle in Project A and then, create a bundle. Then after creating the bundle, load it in Project B? Right now this doesn't work for me using Addressables. Also Addressibles does not seem production ready

Hi, I am in need of suggestions.
I am creating a Mobile game and it contains a lot of objects (roughly 3000 static objects per level) but also a decent amount of levels (20 levels currently)
When the game was a bit smaller (10 levels), it ran more efficiently.
We believe we have optimized most things but it comes mostly down to the amount of objects we have in the game.
We currently store each level in a prefab but these prefabs are also referenced in the scene so we understand that they are all loaded into memory and may cause the increase in lag.
We are looking to only load each level when need but the difficulty comes from the fact that each level mostly shares the same objects.
We have recently tried using Addressables but to no success in performance and I understand that we implemented everything correctly.
We are looking into using "Scene Streaming" next and storing each Level in another Scene. Will this work by any chance?
Also, any suggestions for improving performance is greatly appreciated!

Hi Everyone!

I'm using addressables to distribute remotely content updates. I have a question regarding how the client updates his content. In my design the client checks for updates when the app starts and forces the player to download before continuing. I have implemented this calling sequentially:

1 - Addressables.InitializeAsync
2 - Addressables.CheckForCatalogUpdates
3 - Addressables.UpdateCatalogs
4 - Addressables.GetDownloadSizeAsync for each of the keys of my catalog to get the total download size
5 - Addressables.DownloadDependenciesAsync to download those keys that returned a size > 0

this works properly, but there's a small issue I would like to fix:
steps 1, 2 and 3 download the catalog hash from the CDN. I'm fetching it 3 times instead of one and I would like to minimize traffic to the CDN.
Has anyone found this situation?

They solve different problems. They can split up your final game so you might not need to publish everything to everyone.

Hey guys, I just wanted to clarify. Is it every time I launch my application when there is internet, unity will update the addressable from cache?

I know when I don't have internet it will load everything fine. I just want to know because some of the cache file can be large and with a good number of users it can incur a charge from AWS.
So i just want to know when does unity update the addressable cache, because I was just wondering if it is just when a change is made to cache files?

I couldn't find a conclusive answer to this, so apologies if an answer to this already exists.

I'm getting into Adressables and have a question about moddability.
As far as I understand it, I'd load the built catalog of the mod by filename.

I'd like the user to overwrite existing game data tho, i.e. modifying existing Player Stats. How would I approach that?

#

Loading a new catalog would load them alongside the existing ones, as opposed to replacing them.

#

And unloading a catalog isn't possible, is it?

#

Even if it was, AssetReferences would then lose their reference as it's tied to the GUID, which includes the Catalog, right?

mild flax
mild flax
kind depot
#

Wait, it's possible to replace them?

#

But yeah, it is required to do so while the game is running.

#

I actually do have the moddability implemented, but using Resources and JsonUtility.Overwrite. It works, but using Addressables would be nicer as the modders could use Unity itself and my custom editor scripts for a nicer modding experience.

Do Tilemaps work with Addressables? I don't know how Tilemap serializes its Tiles, but I'm guessing its hard references to the Tile ScriptableObject? That would break the Addressables system.

#

Not sure if this is the right space to ask this. I used to have a texture (2D Sprite) assigned to a game object and in the editor it shows the texture just fine. When you play, it proceeded to show the texture just fine. Idk what I did, but I edited, moved, and renamed some stuff. I reassigned the new texture onto the game object as an image (source image) just like I did before. Absolutely the same exact steps. Shows the preview perfectly fine in the editor mode. However, when I play, suddenly it's just plain white instead of the actual image. This seems like an obvious problem but can't get myself out of it. ANy tips?

#

I have confirmed that the image I'm attaching to the image component of my gameobject is indeed a Sprite (2D) with the correct parameters. It works perfectly fine up until I click play. Then I just get a white fill instead of my texture

#

And that same source image / texture works fine on any other game object except this specific one. Which I just found out. So furthermore points to the game object for some reason

#

Yikes. That one is on me. Was editing the object outside of the prefab and needed to modify the prefab. 😐

sage hinge
#

I don't know if I should ask this here but
I have a folder which contains scripts. When I load an AssetBundle, the desired GameObject (prefab) instantiated on scene load the scripts from the Local Script Folder (with their custom values). So, should be possible to Drag N'Drop the Prefab and save it with all the values. But after make it, the scripts references are missing. I must see the Prefab instantiated, tell the (same) Prefab from my project the specific scripts that are lost after import it, and assign the values manually
Why?

Does anyone know of an API to know whether addresssables is building atm?

When building addressables an Awake is called, and that destroys objects. This shouldnt happen during the build, so i'd like to test this.

Anyone knows how including shaders in addressables work? what happens with .cginc files for example? they are not referenced as dependencies, should they be included too?

gloomy kelp
# mental lily Anyone knows how including shaders in addressables work? what happens with .cgin...

From the perspective of what is included, its a reference in the material like any other.

You can see this if you have serialization to text mode, and open the material in a text editor. It refers to some texture by GUID, and the shader by GUID. No different.

CGINC files dont exist in runtime. When the shader is compiled quite literally, the contents of the gcinc file is copy pasted in the shader file.

mental lily
gloomy kelp
#

How do you refer to them in code? Shader.Find?

mental lily
#

yes

#

(it's not my code, i would have referenced explicitly for better tracking)

#

(but I'm not confident modifying assetstore stuff as it's difficult to track and might be overridden with updats)

mental lily
gloomy kelp
#

Yes, with Shader.Find unity cannot find your dependency, and it wont exist in your build.

mental lily
gloomy kelp
#

No, there is no generic asset bundle. No all other stuff remaining bundle, that doesnt exist.

then how is it that even if i'm not incluing the shader specifically, it still doesnt throw an error 🤔

oak olive
#

I'm not familiar enough with AWS to know how to fix the problem, but the error message seems clear enough; AWS is configured to forbid cross-linking to those resources from other sites. You'd need to change its configuration to allow link origins from Itch's servers (might be tricky, as Itch can change where you're hosted without warning) or just allow all cross origin requests for those resources.

calm walrus
#

with AWS

oak olive
#

Well, yes, it would. Your PC build isn't a web site, it's a client; there's no cross-origin requests happening there, just a client asking for a resource from a server.

#

The problem is that the CORS policy is forbidding requests for the resource from a web site hosted on a different server (in this case Itch or Unity Play).

calm walrus
#

interesting

#

so which serivce should i use

#

cuz idk aws either lmao

swift birch
# calm walrus so which serivce should i use

Unity offers a hosting service, which I believe has a generous free tier. That is what I plan on using for our projects. That said, I have no personal experience yet with hosting services for asset bundles.

oak olive
#

My guess is that most of them would forbid cross-origin requests by default; it's just sensible security practice. So whichever one you use you'll probably need to dig around in the server configuration?

calm walrus
#

gotcha

ugh

#

alright

swift birch
#

When entering Play Mode with a scene in the Editor which is in an Addressables group, does Unity load dependencies from Addressables? Or would it load them through the standard system (I am unfamiliar with what you would call this) and cause duplication?

#

If Play Mode is entered, I have a script run which unloads all scenes and reloads them through Addressables.

I thought this was required to avoid duplication, but Unity Open Project 1 does not perform this reload. So I am unsure if there is a workaround I am not aware of.

calm walrus
#

give it a try

swift birch
# calm walrus i think it does load the dependencies

I am not sure how to check. When I later load a scene through Addressables, it loads the dependencies twice, and they have different GUIDs. The Event Viewer shows only a single use of the resource, not two. But I don’t know if that is just a quirk with loading it through the Editor first

I have a scene loaded in the Editor. That scene is also in an Addressables group. When I hit “play” to enter Play Mode in the Editor, does it correctly pass the already loaded scene through Addressables so that shared dependencies are correctly marked as loaded and are not loaded twice when I later load another scene through Addressables?

I am currently trying to figure out how to test this to know for sure

#

It looks like duplication is only happening with the Use Existing Build script, but that has me concerned that there are still issues that are just being masked by the other two Play Mode Scripts.

Hello Everyone, just a simple question : How can I apply "Simplify Addressable Names" via script ??

neon vortex
#

When building manually and calling AddressableAssetSettings.CleanPlayerContent(); when we're done, there's still a AddressableAssetsDAta/<platform>/addressables_content_state.bin file left over. Is this intentional? We want that to be removed when doing cleanup, I'm curious if there's a more proper/idiomatic way other than using System.IO to delete the folder using ContentUpdateScript.GetContentStateDataPath() to get the path.

What's the difference between addressables and serialzedfield?

#

You both set in the inspector and both use to instantiate

low halo
# formal depot What's the difference between addressables and serialzedfield?

the main difference is that when you reference something directly with a serialized field it gets loaded into memory immediately when the thing that references it is loaded.

For addressables it's merely a lightweeight asset address that gets loaded immediately, and the full thing isn't loaded until you ask for it.

Hello everyone, I have a question, not sure if someone with more experience could have an answer.

I've been working on a project where I'm synchronising the appearance of networked players by sending the AssetGUID of an Addressable through a System.Guid object and then recreating the AssetReference on the client, but since I updated my project to Unity 2021.2 and the latest Addressables version this stopped working, doing some tests it seems the Guid format is not normalized when creating an AssetReference while the main Addressable system requires the Guid (RuntimeKey) to not use dashes (The default behaviour of System.Guid.ToString()) otherwise it will throw an InvalidKeyException, this was working before, not sure what might have changed, but the question is:

Should I be using a different container (In general, not network specific) for the GUID of the AssetReference or is there some best practices I could refer to based on my use case?
Thank you

low halo
# slate timber Hello everyone, I have a question, not sure if someone with more experience coul...

If possible, since this is going over the network, instead of sending the string version of the GUID, why not send the raw bytes (16 bytes) and construct the GUID from bytes as well.
https://docs.microsoft.com/en-us/dotnet/api/system.guid.tobytearray?view=net-6.0#System_Guid_ToByteArray
https://docs.microsoft.com/en-us/dotnet/api/system.guid.-ctor?view=net-6.0#System_Guid__ctor_System_Byte___

That should be consistent and also more performant/less bandwidth to boot

low halo
oak olive
# low halo Bumping this question again since it's been a couple days... Still not sure how ...

This possibly isn't the most helpful answer, but I would just debug it? We have source for the addressables library, and it's a straightforward null reference exception, so I would start by looking up exactly what it's dereferencing and following back where the null came from. Unfortunately I don't have that version of the addressables package handy so I can't check the file and line myself.

Hi, this is about asset bundles but I think this will be the appropriate channel..
Have any of you got this error while downloading and loading the asset bundle from the web :

Hallo. I'm trying to build separate version of our game and demo. my first thought was to have separate groups for main_scenes and demo_scenes which would have overlapping content but the demo_scenes would only include the scenes used in the demo. I'd then uncheck "Include in Build" for which ever one wasn't going to get used before building.
The big problem I'm hitting is that if i add a scene to demo_scenes it is then removed from main_scenes.
Any ideas how i can stop this?

So a colleague added Addressable Assets to our project, and upon checking out the project with the new addressables dependency, Unity touched the AddressableAssetSettings.asset file adding my local computer IP (to my colleague's already listed local IP). This doesn't seem sensible to me. Is there a way to prevent Unity from adding the IPs to the code base? I haven't seen any serialized editor property for those settings, so I also wonder what those are?

unknown.png
#

The changed and added private IP addresses, are those of two different local adapters I have on my development machine. These are also listed when starting a local asset hosting server. I assume this allows game clients to use my local Editor for downloading the assets. However, having those IPs in version control seems bad, as it will keep touching those files in a team environment.

I don’t have a solution unfortunately, but I did discover that this is only an issue with Addressables 1.19 and not 1.18. I am hoping it is a bug which will be fixed soon, because I could not find a way to disable it and it is causing noise in our repositories as well.

It also seems to store the private IP regardless of whether you are using the hosting service or not. So removing local hosting services likely won’t fix the problem.

Since the file also contains shared configuration, adding it to .gitignore would lead to devs not noticing when"real changes" are made that they need to add to VCS. Ultimately, all is a compromise, but smudge filters seem to cause the least amount of issues in team environments.

If you're instead asking why it happens, I believe C# picks the more specific overload without considering deprecation, and since IList[] is more specific than IEnumerable it's the preferred choice. As such deprecating the IList version was probably an incorrect decision; they should have just removed it and let calls silently fall back to the IEnumerable version. (Assuming the two methods do the same thing; if they don't that's its own horrible can of worms.)

Figured out what the issue was, I built the project and was able to load the addressables. What was happening is that I have a post build code that removes the StreamingAssets folder for other parts of my project that use it inside the editor (I eventually delete this folder after build since I will be downloading my assets so I just wanted to automate the process and remove the folder with a post build script). Apparently Addressables saves a folder in the Streaming Assets folder which eventually gets deleted thus not allowing the assets to load...

hey guys, my project has custom mapping that uses asset bundles to load maps that players can create using unity. I have a system setup that strips all the textures from the bundle build that are already included in the built game files (default assets) to reduce file size

#

up until now, i was using the resources folder to load these assets

#

im fed up with this system cause each time i update the game, a huge update is sent to steam (several gb even with nothing moved in the resources folder)

#

im trying to figure out the best way to handle what i want to do, and im thinking of using either asset bundles for the textures, or the addressables system

#

my question is this: if i were to bundle say 150 textures into an asset bundle, and i needed to load only about 15 for a specific map, does unity have to first load all 150 textures in the asset bundle before i can apply the textures i need to their materials?

#

and, if you know of any better way to accomplish what im trying to do, please let me know!

swift birch
# muted ocean my question is this: if i were to bundle say 150 textures into an asset bundle, ...

The “Memory Management” section of the Addressables manual says that an asset bundle’s contents can be partially loaded, but not partially unloaded. So you should be able to load those 15 textures, and as long as the other 135 textures in the bundle aren’t referenced anywhere they should remain unloaded. However, once you load those 15 textures, they will remain loaded until there are no more references to the asset bundle they were contained within. This means that when you load another group of textures for another map, the textures you had previously loaded will not be unloaded.

You will probably have to experiment with this using the Event Viewer to find an arrangement that works for your situation. You may need multiple bundles to ensure that textures are unloaded when no longer needed.

Edit: That said, what you want to do with custom maps where players can create them within Unity and then get loaded by the game is a fairly advanced use case and is outside of my experience with Addressables. Because of this, you might have additional issues with loading the textures that I am not aware of, and I can’t comment outside of asset bundle partial loading.

return go;

When I instantiate a Prefab, for example, this is not how it works.

In my exp verified has as many bugs as non-verified versions. I assume the only difference is that it's an editor+package combination passed some automated tests or something.

We approach this by just trying (if we have issues) then rolling back if the issues are worse.

While debugging this issue, I discovered a different unexpected behavior: If you load an asset through that code, and the asset has sub-assets, such as a TMP_FontAsset, it will attempt to load the root asset and all the sub assets. This causes an exception due to a type mismatch between the root asset and the sub assets. This is solved by supplying the type to LoadResourceLocationsAsync().

This is documented in the Addressables manual under Using Addressables at runtime -> Loading Addressable assets -> Loading locations of sub-objects. This was unexpected for me personally, so I thought it might be worth bringing up, in case it’s helpful to someone else.

# lucid mulch i just skipped those error and they worked like nothing happen. that weird 😅

It is pretty strange. I spent 6 hours yesterday attempting to intentionally break Addressables in this way, and I could not figure out how.

The error is caused by a null value being returned from AssetDatabase.LoadAssetAtPath() and Addressables attempts to use this null value without first checking if it is valid. But because of previous checks and code, I don’t know how it’s actually getting to that point at all; in my tests, it always errors out before this point.

# low halo thanks

Oh! One issue though that I should mention: If you are using the Asset Database Play Mode script and you have an asset that is both marked as addressable and within a folder that is also addressable, there is a bug where the asset will be returned twice. I believe the bug affects LoadResourceLocationsAsyc() but I cannot remember if LoadAssetsAsync() is affected. I encountered this bug in 1.18.19

low halo
#

What's the major difference betwen LoadResourceLocation and LoadAsset btw

swift birch
#

@low halo You can get resource locations without being locked to a specific type if you use LoadResourceLocationsAsync(). This was actually the cause of a bug in my case, because I did not expect it. It might be useful if used intentionally though. The manual also mentions using it if you need to create an association between the key and the asset that was loaded with that key, as LoadAssetsAsync() does not guarantee that the assets are loaded in the same order as the supplied keys. This is mentioned at Using Addressables at Runtime -> Loading Addressable assets -> Loading Multiple assets -> Correlating loaded assets to their keys

Besides that, I haven’t seen a difference between the two. I’ve been preferring to use LoadAssetsAsync() where possible to increase code readability.

low halo

Has anyone ever seen an issue where LoadAssetAsync never finishes? It doesn't get an error or anything, it just dies completely. The completed event is simply never called. Nevermind I'm being stupid.

you of course have to wait for the operation to succeed. i don't know what tutorial you're using

#

maybe they don't use the async variant

swift birch
# wicked frigate how do I make it not be null?

The AsyncOperationHandle returned by InstantiateAsync() will not have a valid value in .Result until the AsyncOperationHandle completes, and it needs to complete successfully.

To be notified that an AsyncOperationHandle has completed, you can subscribe to its .Completed event. You can also yield return the handle inside a coroutine, which will yield until the operation completes. You can also poll .IsDone periodically in a location like Update(), but I recommend using a coroutine or an event listener instead as the code will be easier to work with. If you are comfortable with async/await, you can also await the handle’s .Task.

For further information, I recommend reading the Using Addressables at Runtime -> Operations section of the Addressables manual. It includes code examples.

You can use the Analyze tools to check which assets would be added in as duplicates. This is the one 'fixable' rule. You can run that, and it will tell you (and can fix for you) which assets will be duplicated across bundles

It will put all duplicate assets into one single Addressables group. You can move them around to other groups afterwards if that makes more sense for your project structure

Will UnloadSceneAsync remove the scene from the cache, or not? I've found different sources claiming the opposite

Is there any way to make a "dynamic" catalog where resources can be summoned by request in a particular address space?

#

Something like "all addresses within foo/bar/ may exist, if the cache hasn't already resolved it, ask this provider to check for its existence on-demand"

shrewd geyser

# covert verge Oh heck I didn't see this channel. Sorry, I posted this in advanced code by acci...

Hmm, no, Addressables doesn't really lend itself to that. It would in a resource managing/loading aspect of it, but not in the generation-aspect of user generated content. Especially not from within the game.
In theory I would think this is possible if your players downloaded the Unity editor and had access to (part of) the code and assets that they require to build their content, but something like this isn't possible from within the running game itself as a lot of tools for building are not available in the player.

shrewd geyser

#

I was under the impression that custom providers still required catalogs that resolved to a fixed set of contents

#

e.g. you can't ask for a resource and detect which catalog to try to load based on the address requested

shrewd geyser
#

Hmm, that's true. 'A' catalog is indeed required to be loaded. But I think it's up to the provider how it handles the catalog in terms of how to search for the requested address. Perhaps the catalog can be somewhat different than the default generated ones and provides your custom provider with hints as to what to load. But perhaps that's taking it too far already (and I'm just speculating of what I would investigate, but I can't say for sure something like that will work)

next rune
#

Ohhh, so you're suggesting there may be room to overload the catalog interface itself and use that to determine "if it contains an address"?

shrewd geyser
#

Yeah, something like that

next rune
#

I'm not sure I can tell which interface is appropriate for that; I'll have to dig deeper- but if anyone has any information on what might be the right interface to override, I'd be glad

that's not really an addressables question- but you can use an async function and await Task.delay(x * 1000) between setting the variable and resetting it

i'm noob addressable user
i need help if this problem below is a bug or if there is anything i missed

Question 1
AssetReference is null when "Use Existing Build"

  • Scene, Prefab, Object are all added to Addressable group
  • Clean, New Default builded
  • It's working normally in fastest mode
  • The problem is not reproduced in the sample example using Addressable 1.18.16 (same setting...)
#

this problem does not occur when playmode in that scene,
when loading the scene through LoadSceneAsync, all of the things binding to the
scene's AssetReference change to null

twin sparrow
#

"Fastest" mode would not use the bundles, it would just serve it from the assetdatabase

#

are you sure the bundle is being built?

pale marten
twin sparrow
#

search your project/Library/ folder for *.bundle

pale marten
#

in Library\com.unity.addressables\aa\Windows\StandaloneWindows64

#

Right below the Library folder, There is no *.bundle file.

twin sparrow
#

yea, thats the right location for it though. is that the bundle you were expecting?

#

(did you define any other Packed groups?)

pale marten
#

To simplify the problem, i currently have only Default Local Group, removing all groups.
Shall i make a new group?

twin sparrow
#

I saw a ping. did you send something?

pale marten
#

Perhaps the setting of the Discord channel erased the mention message immediately.

twin sparrow
#

lol yes

#

(if its a big ol' script paste yea it'll nuke it)

#

editor only serialization will indeed go null if drawn from built stuff

pale marten
#

Is this normal to happen when #if UNITY_EDITOR is used?

twin sparrow
#

that compiler directive will hide that code anywhere except when using UNITY_EDITOR

#

so serialized variables wont serialize in a Build

#

that can have weird implications in an AssetBundle

pale marten
#

Thank you for your kind answer. It was helpful. 🙂

I have a problem when loading scene with LoadSceneAsync (additive, activeOnLoad true)
when i load scene with LoadSceneAsync
and Scene was set to be active with SetActiveScene,
lighting of SceneView looks abnormal, but GameView looks normal.

There is no such problem if i load the Scene by SceneManager.LoadScene (not addressable) way
The hierarchy item is also different when using SceneManager.LoadScene and Addressable LoadSceneAsync

which part should i check?

I solved the problem.
The problem was the always refresh option for the scene editor .

austere rune
#

So, I'm experimenting with Addressables.LoadSceneAsync / UnloadSceneAsync.. and it seems like it's failing to clean up memory properly (textures and meshes), causing a memory leak. I found a couple of old threads about it, but seems this has not been fixed yet?

Fresh project, using the urp sample scene to experiment with.. Getting these results:

I have rooms that are addressables.
rooms have doors, but the doors are children of the room, and cannot be addressable themselves.
How do I reference a specific door within a room after loading the room addressable itself?

#

Ive tried googling it but I cant find any example of targeting a child of an addressable

wicked frigate
#

Is there a way to reference the child of an addressable?

#

drew a diagram to make it easier to understand

Going to the Room is the easy parts, Doors have AssetReferences to the addressable Room, but afterwards I am not sure what kind of data type will allow me to target the doors within the room

swift birch
# wicked frigate Going to the Room is the easy parts, Doors have AssetReferences to the addressab...

You could create a serialized class that represents the door, and contains its Transform reference and an int field that stores its ID. Then store a list of these serialized classes instead of the Transforms.

Alternatively, you could create a MonoBehaviour that stores an int field for the ID, and add that to each door. Then store a list of these components instead of Transform or use GetComponent.

A thought I just had: You could create an empty ScriptableObject and create assets of it for each door in your game, and then use reference to that asset instead of an int ID. That way you don’t have to remember which numbers go to which doors while designing rooms. Room C’s Door 2 and Room A’s Door 1 would both use the same ScriptableObject asset as their ID. Normal advice for working with ScriptableObjects and Addressables applies regarding dependencies and accidental duplication.

wicked frigate
#

Doors wont explicitly return the way they came is my thought, Door D might not even go to A B or C in that example

swift birch
mild flax
#

Small note on ScriptableObjects + addressables - the ones in a build will not be deserialized as the same Unity Object as ones from addressables. So, if you have a class in your main app that references SOs (e.g. a 'door mapping' monobehaviour) - they won't reference the same objects as the ones that are deserialized in your door prefabs.

I have a custom inspector that I need to load an addressable to get some information from it in the project, is that a bad practice?

#

Loading addressables in Editor while the game is not even running I mean?

#

X/Y question maybe, hold on

#

How do I get the prefab an addressable refers to for use in a CustomEditor Inspector?

#

its an AssetReference currently

wicked frigate
# wicked frigate

In this example Asset is null because I wasn't loading the Addressable before trying to access it

#

my addressable is always null it seems, Im guessing you just cant load addressables from editor scripts when the game isnt running?

#

"Addressbles just isn't set up for editor loading (outside of play mode)"

#

Well this is a bit of a problem for me

#

I need info about the prefab the addressable is addressing in editor, and the only reference to it I have is that addressable

# 
    public static T LoadInEditor<T>(this AssetReference assetReference) where T : UnityEngine.Object
    {
        var path = AssetDatabase.GUIDToAssetPath(assetReference.RuntimeKey.ToString());
        return AssetDatabase.LoadAssetAtPath<T>(path);
    }
#

Found this online, might be the solution I need

#

My AddressableReference returns "[]null" and this gets past my null test

#

What is a []null and how do I check for it and stop it?

#

I thought it was maybe a string because its in quotes, but no dice

pale marten
#

noob question...

I understand that 'group' is a unit that is grouped into real files, and 'label' is a unit to find items like tags.
Honestly, this concept doesn't really touch me.
I'm curious about the exact use and difference of group and label.
q1) I want to know when to choose and what to spend.
q2) What does it mean to check "folder" as addressable?
(How sub-folder items are handled, when they are used)

shrewd geyser
#

Groups and labels are really separate concepts, used in different ways.
Groups are mainly used for the build process and how/where the player will load them from, like physically.
Labels are a runtime only concept of what assets you want to load.

A group contains the assets how you structure them and what makes sense for your project. If you have a sword asset with several skins for it, you can group those in a single group, and armor with different skins in a different one, or group all equipment together in a single group. Whatever you choose and how you want the Unity player to load them in (you can customise several settings on a per-group level). If you have assets that need to be available immediately, for example, like several UI or manager objects, then keep them local. If you have end-game levels or monsters, then you can put them in a group that will be downloaded from an external source later and save some disk space for players that haven't reached this end-game content yet. The concept of a group does not exist anymore during runtime, because Addressables doesn't care anymore at that point.

A label determines which asset(s) you want to load at runtime. If you have multiple assets with the same label spread over several physical locations, it will try to (download and) load in those assets (of which it knows about through the catalog file created during build), regardless of how they were grouped.

fervent lintel
#

Does anyone know what I'm maybe doing wrong? I'm using one scene that handles the loading of scenes with addressables; it loads a scene, unloads the previous scene, etc. All works perfectly fine, except for the lighting options. When I open my scene directly in the editor and play it, there is no fog, when I load it through my scene handling scene, there is suddenly a fog. The scene handling scene has no fog, but the unloaded scene did. Is it not unloading the lighting settings?
Edit: It's actually making the light less intense, rather than doing anything with the fog

lilac linden
#

How to make sure addressables load on game release? Game runs perfectly in editor mode, but when I compile the release, some addressables (textures) won't load at all.

#

Is there some catch that I didn't know?

wicked frigate
#

After I finish preloading an addressable, what is the syntax to then instantiate it?

    public static void PreloadTransition(AssetReference room)
    {
        Addressables.LoadAssetAsync<GameObject>(room).Completed += ObjectLoadComplete;
    }

    private static void ObjectLoadComplete(AsyncOperationHandle<GameObject> obj)
    {
        if (obj.Status == AsyncOperationStatus.Succeeded)
        {
            //Instantiate happens here.
        }
    }```
Would I use the regular Object.Instantiate in this context?
wicked frigate
# mild flax correct

It's now tomorrow and I find myself needing to make that exact check. 💦
I got instantiation from addressable working, but now I need to make sure I dont instantiate a room that already exists

#

someone online suggests a dictionary of assetreference, gameobjects. Ill try that

wicked frigate
#

The net says absolutely DO NOT use Object.Instantiate, but it doesnt say what I SHOULD use in its place

mild flax
shrewd geyser
# wicked frigate The net says absolutely DO NOT use Object.Instantiate, but it doesnt say what I ...

We use just Object.Instantiate to instantiate Addressable assets. It's just that the automatic unloading mechanism won't know about it, and you'll have to release manually when you know you're done. It's not wrong to use it, it's just a bit more work to keep track of what you're doing.
In our case, we had a big project already which we were switching over to Addressables, and we already kept track of what was loaded in, so we kept doing it, since this approach translated really well to Addressables.

#

I've been working Addressables into my game and I got it working stable in editor. I did a build to test it and I got this error in build but not in editor.
I'm not 100% sure what it's saying but it looks like its saying it failed to load the addressable?

unknown.png
#

This is the first build I've built with addressables so I assume I must have missed a initialization step when you add addressables to the project maybe?

#

Do addressables need to be in a special folder like how Assets/Resources do?

#

I found a link online but I cannot find this "addressables" menu with mode selection. I went through Window>Asset Management> all the addressable window options, but none of them were just flat 'Addressables'

#

hmm the net says "Window > Asset Management > Addressables) "

#

Im guessing the online resources are out of date? because that isnt a window that can be opened on latest unity

#

I keep finding reference to an "addressables" window but I dont seem to have that window

#

I found this but Im struggling to parse what im supposed to do from it

#

I've read this block 4-5 times but my brain cant seem to grasp what Im supposed to do to get this in my project happening

#

I dont mind it taking longer to make builds, but how do I actually make it do that?

#

I guess my question at the end of all this is:
How do I make it build automatically when I make a normal unity build? I cant find a straight answer online that says "do X"

wicked frigate
#

my asset settings seems to be missing some data compared to the doccumentation?

#

As far as I know I am on latest

#

It looks like the setting I need is under "Build" but I don have build UnityChanThink

#

hmm

#

im NOT on latest

#

im on 1.16.9

#

but there is no option to update

#

Im not the only one with this problem it seems

#

the changelog on addressables says there are tons of stable not preview releases after what I am on so I am not sure why I can't update?

#

I found out how to update to latest

#

but the option -still- isnt there

#

there is supposed to be a check box for "build addressables content on player build"

#

unity never makes things easy

#

How do I build my addressables automatically when I make a player build?

#

I feel like I am taking crazy pills

#

same version, same setting object, completely different settings to what the doccumentation says should exist

#

oh im on 2020 thats why I cant find it :|

#

"Building Addressables on Player Build requires Unity 2021.2+. In earlier versions of Unity, you must build your Addressables content as a separate step."

#

now I have to figure out how to do this "separate step" automatically when I make a build

#

woo okay I am in buisness, found a script online that does it

#

I am getting a big lag spike in Build and in Editor when I run Addressables.InstantiateAsync(room).Completed += loadComplete =>
I have never used the Profiler before so I am not sure what its telling me to tell what is causing the lag spike however. It appears its related to physics callbacks maybe?

unknown.png
wicked frigate
#

hmm if im reading this right, InstantiateAsync isn't being async, its sitting and waiting for it to finish loading?

#

which is what I feared is happening

#

I get a huge lag spike when I call LoadAssetAsync, I am not even instantiating it, just loading it alone, In Build (but also in editor)

wicked frigate
#

hmm even this causes a big lag spike at 5s

#

I think I solved it

#

there is a large lag spike associated with running LoadAssetAsync for the first time

#

if I run it, loading a blank prefab, at start, all subsequence calls of that method cause no lag spike, regardless of the size of the thing being loaded

wicked frigate
#

Doing that made it work, I solved it in the end, no lag anymore

wicked frigate
#

I have a dictionary of my instantiated addressable rooms, I am using AssetReferences as keys, and the instantiated room as values

#

but for some reason, 50% of the time when I pass in the AssetReference, it returns null

#

when it sees null room, it assumes the room has not been spawned, spawns a new room, and then logs it with the AssetReference/Spawned room

#

when I debug log the contents of the dictionary, I can see there are multiple of the same room spawned, and using the same identical AssetReference key

#

I can't figure out why it returns a null when logging shows the same identical AssetReference Key saying there IS a room to return

#

I say 50% of the time because I use this code in two places, and I dont know why but identical asset references as key, the same copied value, will return the room in one place, but wont return the room in the other place, and I cant figure out why

wicked frigate
#

when I debug log an AssetReference, this is what I get

#

but when I thing == thing them, they are not returning as equivalent

#

for now, I am doing AssetReference.ToString(), because that DOES return as equivalent

#

are there unforeseen circumstances to this solution/action?

wicked frigate
#

Hmm

#

My ToString sollution didnt work

#

it worked sometimes, but after further testing, the strings dont always align

#

I need some way to pair up asset references with instantiated objects in a dictionary that is no fail

#

thus far every attempt hasnt worked

#

Okay I have no idea whats going on, because now I cant reproduce the dictionary not returning

Yeah but I'm not loading the bundles yet, just trying to Initialize Addressables first...I was having the delay issue with just downloading the catalog instead of initializing so that's why I thought maybe I should initialize first then download later so it could be faster.

I'm trying to get some insight on what would the correct pattern would be for an Items system. Starting with an enum of ItemIds, each item prefab holds one of these ids, the way I see it right now I have two options either:

1 - Make sure the address is something like "Items/[itemId]" and when I need an item, do a LoadAssetAsync. Which seems weird and kind of prone to error, having to make sure the strings match both in the enum definition and in the address.
**2 - **Loading all addresses with the "Item" label on startup, and mapping them to a Dictionary<ItemId, AssetReference>, which seems a bit overkill maybe? And is a whole process on boot?

Maybe I'm overthinking it, or there is even a completely different approach I'm not seeing. In any case, I would appreciate any insight on this

I am very new to addressables, but would like to understand how I can use addressables to solve adding custom animations into my game after release. Something like what Fortnite did, I need to find a way to add more custom animation into the main character's animator controller, and access them via code without knowing what those animations are.

#

Are there any working examples of this in action I can review?

#

I am currently using asset bundle to load the animation and other custom clips, but would like to give addressables a try.

marble bay
# lunar garnet I am currently using asset bundle to load the animation and other custom clips, ...

I used this to get started: https://gamedev-resources.com/load-unload-and-change-assets-at-runtime-with-addressables/

Load, unload and change assets at runtime with Addressables - GameD...

Addressables are considered "the right" way to manage assets within your game and helps tremendously with memory allocation. Get an overview of what the Addressable system is, the benefits in using it while learning how to dynamically load/unload an addressable by instantiating a prefab and changing a texture reference.

#

For the animations, I would retrofit the Texture loading section of the tutorial for animations instead...

lunar garnet
#

Thanks! I'm researching on another problem regarding of Unity's animator and how I could load custom animations at runtime. It seems like I'll have to use a plugin called animancer to resolve that.

All good. I'll read the article you sent me. Thanks!

#

Now for people more adept at Addressables than I am can someone give me the basic anatomy of the files I need when loading from a remote server? The problem is I don't know what files I need to delete from remote server and what to keep when I make changes to the Addressables group. When to build the whole project again vs when to not to (and just build the Addressables group instead)...any help?

#

These are the files I have:

#

The craftastechlogo_assets bundle file I know is what gets updated with catalog but what is the "faad2dab2f6d33164579cd0" bundle file?...

#

And what are the catalog files there?

torpid crescent
#

either upload it on server or cache and reuse is fine

marble bay
torpid crescent
#

if catalog changes then you need to upload it

#

it is used to access the files

#

if it's not on the catalog, you can't access it

marble bay
#

What do you mean changes? New stuff added to addressable groups?

torpid crescent
#

you don't have to upload it, but you don't have to upload anything either 😛

#

what I meant is that you could ship it together with the build if you want to

#

... I think

torpid crescent
marble bay
torpid crescent
#

there should be a 'build content' and a 'update content' option

#

use the 'update content' when you're updating content

#

also, ignore everything I told you about the catalog.. just upload it too

dense cosmos
#

Hello. I'm fairly new to addressables and wanted to ask what is the best way to separate catalogs that are in the dev environment vs production.
I understand that if I build my project with a certain Profile selected, that build can only load assets from one RemoteLoadPath (hosted on a CDN).
So if I wanted to make a dev build to hand over to my beta testers, I would have to build my game using a different profile that has a different RemoteLoadPath. Is this the best way to separate dev catalogs/bundles and production ones?

Update: I found a section of the documentation that answers my question: https://docs.unity3d.com/Packages/com.unity.addressables@1.18/manual/BuildingContent.html

dense cosmos
marble bay
torpid crescent
#

yes :p

torpid crescent
#

and use the same catalog, if you wish

marble bay
# torpid crescent yes :p

So I'm basically replacing all the files then. So process is upload new files, then delete old files?

torpid crescent
#

that's what I'm doing

#

(actually it isn't but you didn't seem to like what I said about the catalog files xD)

marble bay
#

I just need to know the proper process...

#

What files never (?) get reuploaded vs what files that do...

torpid crescent
#

do you know how to access addressables?

#

@marble bay

marble bay
torpid crescent
#

like.. instantiate

#

how to get a reference to the asset file in Unity

marble bay
#

Yes, I've been using it in my tests after I build the project...

torpid crescent
#

cool, then how do you do it?

marble bay
#

I use it as Asset Reference...

#

Then instantiate it...

torpid crescent
#

I see

#

what if you didn't use AssetReference?

#

you know how you could access it?

marble bay
#

I currently store my prefab in the Asset Reference variable from the inspector...

torpid crescent
#

alright

marble bay
torpid crescent
#

so, the AssetReferences come from the catalog

#

so you could have the catalog contained in the built (resources folder or w/e), so no need to upload it

#

now.. the catalog links the AssetReference to an asset, when you first 'load' it (be it either Addressables.Instantiate or Addressables.Load())

#

the link usually points to a server (or a local path, depending on your addressable build settings)

#

so, you don't really need to upload anything to a server..

#

now if you DO want to use a server, you can either upload the catalog or don't

#

-- based on if you prefer to have your catalog included in the build, or accessed via your server

#

the '.bundle' files need to be re-uploaded regardless

#

NOTE: not ALL .bundle files will need to be re-uploaded each time you 'Update content' (since the catalog contains the same links)

#

but to be safe, you can just upload and replace everything

#

NOTE: if you DON'T Update content, but REBUILD instead, your AssetReferences will be lost, so you'll need to both update them and your server files

#

@marble bay makes sense?

marble bay
#

So after I build my addressable group, never rebuild? Just update?

torpid crescent
#

optimally, yeah

marble bay
#

Doesn't Unity automatically build the addressables groupd when I build my project again?

torpid crescent
#

that 'build' is just an export of what's currently in

#

it's not a full rebuild

marble bay
#

We need to pin your posts up top for this thread lol, i need to come back to it!

torpid crescent
#

I'll ping one of the mods to do it once someone confirms it's correct info lol 😄

#

not 100% sure about AssetReferences being lost since I don't use them, just read something of the sort and been avoiding them since 😛

marble bay
#

Thanks though!

I'm trying to get some insight on what would the correct pattern would be for an Items system. Starting with an enum of ItemIds, each item prefab holds one of these ids, the way I see it right now I have two options either:

1 - Make sure the address is something like "Items/[itemId]" and when I need an item, do a LoadAssetAsync. Which seems weird and kind of prone to error, having to make sure the strings match both in the enum definition and in the address.
2 - Loading all addresses with the "Item" label on startup, and mapping them to a Dictionary<ItemId, AssetReference>, which seems a bit overkill maybe? And is a whole process on boot?

Maybe I'm overthinking it, or there is even a completely different approach I'm not seeing. In any case, I would appreciate any insight on this (edited)

Righto, just making sure I've not missed another way to update the catalogue

# marble bay So after I build my addressable group, never rebuild? Just update?

Sometimes you have to do a new build of the addressables. I updated the version of Unity for the project, and doing an update catalogue build wasn't enough, had to do a new build. So that users who hadn't updated the app wouldn't get a broken app, I did a new build into a different folder
Original: /ServerData/Android
New: /ServerData/Android_2022325

And have both on the S3 server

marble bay
undone hound
#

We don't yet, but it's very common to do so

#

eg: MP games like Clash Royale

marble bay
#

In terms of how I am using it, its a web app so no downloading, you would load the latest version when you boot up page. Now I am questioning how to remove the old version and what happens if we do when player is in the midst of using the program? Or is that why companies do server maintenance times?

undone hound
#

That, I'm unsure about, I haven't touched addressables in WebGL.

I THINK it wouldn't matter for a user who's already playing when you update.. unless/ until they get to a section that requires a download from the addressables that they haven't already gotten yet

#

Depends when you get the addressables, and if there's any refreshing during gameplay

marble bay
#

Nah, they load the addressable from the beginning...

#

Guess it never hurts to test myself...

wraith edge
#

If you expect extended session times and rapid update cycles, maybe a smarter setup needs to be implemented

marble bay
#

Probably just gonna roll with keeping 2 different catalogs up at a time (oldest and newest) which gets replaced with each new catalog change...

#

But is the system smart enough to load the latest catalog?

#

Or do I have to manually do something here?

#

For anyone who is using the Localization package, what is the best practice for structuring the asset files. I notice that when I create a string table, it puts all the assets in one directory (that you choose) and its flat. Is it possible to move around the assets so it follows a locale language per directory with the table reference in the root or something?

undone hound
#

and doing so, requires a new game build

#

You might be able to get around that by having a json (separate to the addressables) that has a version number + which URL to use. Check this on game load, get the latest URL, and pass that to the addressable system

marble bay
undone hound
#

setting the string url as pathA or pathB

marble bay
#

Like having two separate folders

#

That point to the Old and New Builds?

untold jewel
#

How does one remove a localization string table used by the localization package? They don't have any documentation on how to remove localization tables/assets the right way. I don't want to manually have to remove stuff in the file system.

Hi all, in 1.19.17 I'm getting stack overflow on AssetReferenceDrawerUtilities, it's caused by using F-Bound polymorphism to construct a scriptable object that is an addressable.
Something like this:

    public abstract class AddressableObject<TContainer> : ScriptableObject
        where TContainer : AddressableObject<TContainer>

Function causing the issue:

        private static Type GetGenericType(Type t)
        {
            if (t == null)
                return null;
            while (t.GenericTypeArguments.Length > 0)
                t = t.GenericTypeArguments[0];
            if (t.BaseType != null && t.BaseType.GenericTypeArguments.Length == 1)
                t = GetGenericType(t.BaseType);
            if (t.HasElementType)
                t = GetGenericType(t.GetElementType());
            return t;
        }

Is this something known?

Hey, new to addressables and assetgroups, I have a quick question. If I were to mark a scene in my project as "addressable", and none of the meshes/textures/sound files/etc. in that scene were referenced elsewhere in that project, would all of the asset grouping for those subassets be 'automatically' handled? Or do I need to maintain explicitly-dictated assetgroups of individual assets separate from that?

I have a question. Why can't I drag and drop bulk items into a list of AssetReferences like I can with GameObjects and Audiclips? https://youtu.be/-HBXztlxR7k

Unity Addressables list, bulk importing.

Rules violated:

  1. consistency: If lists for everything else in Unity allow bulk importing, so should addressables.

  2. Time violation: Should be done in seconds, not minutes or hours

  3. Focus lost: Drag and drop loses focus

  4. Frustration: knowing you're losing time due to lack of consistency is annoying.

Am I doing things wrong? Or did Unit...

Hi everyone, I currently finding a way to load my assets remote, because of the limit of the google store (150mb), I think addressable is a good way, so my question is, I can make my assets (textures under Resources folder) as addressable assets and then in the app download the assets, and I can still use "Resources.load" to load my assets as usual?

That's a problem with asssetReference type when they are a list

#

This isn't really a problem with addressables. If you're ever in a situation where you have one object loaded and 98 from the same bundled unloaded, your asset bundles are set up wrong. With addressables it's pretty straightforward to set things in discrete bundles.

#

Also, addressables are asset bundles. It isn't either/or. And you should never use Resources.

I started to work on upgrading my project to use Addressables. I was using Addressables thanks to Localization package before.
I'm trying to do it correctly, that's why I'm using Addressables Event Viewer. It's very messy though, because of multiple "GetTableEntryOperation" that are caused by LocalizeStringEvent. I don't know why some of them get unloaded when destroying gameobject, but some of them stay in memory even when I remove whole prefab or switch the scene. Should I somehow release it from memory by myself?

I am getting a weird bug with Addressable that I'm having trouble nailing down the source of.

In a pc Build, not in Editor, I am using a render texture as part of a visual effect. The Render Texture is populated from a camera.

If I drag a prefab into the scene, the render texture works as expected, however if I instantiate that same prefab through an AssetReference, the render texture returns black

#

I've carefully compared every single thing within the Addressable instantiated room vs. dragging it in manually, and I can't find a single difference between the two that could answer why the render texture is black in any of the addressable prefabs

#

Is it possible that something is being done to the sprite renderer that is in the scene at launch that isn't being done to the sprite renderer when the addressables instantiates the prefab?

wintry karma
#

Should we handle caching for addressable assets ourselves?

#

I mean if we do not handle it, they are downloaded completely every time?

public IEnumerator Start()
{
    string key = "assetKey";
    //Clear all cached AssetBundles
    // WARNING: This will cause all asset bundles to be re-downloaded at startup every time and should not be used in a production game
    // Addressables.ClearDependencyCacheAsync(key);

    //Check the download size
    AsyncOperationHandle<long> getDownloadSize = Addressables.GetDownloadSizeAsync(key);
    yield return getDownloadSize;

    //If the download size is greater than 0, download all the dependencies.
    if (getDownloadSize.Result > 0)
    {
        AsyncOperationHandle downloadDependencies = Addressables.DownloadDependenciesAsync(key);
        yield return downloadDependencies;
    }

    //...

I' using Photon Fusion and now I'm trying to implement Addressables. When I initialize my MP game I load my chapter prefab, if player is a host (or plays single player mode) I have to spawn networked prefab in Completed callback, just like this:

        {
            Debug.Log ("Spawn for host and single");
            roomHandle = Addressables.LoadAssetAsync<GameObject> (string.Format ("Room_Chapter{0}", chapterId));
            if ((Runner.GameMode == GameMode.Host || Runner.GameMode == GameMode.Single) && Object.HasStateAuthority)
            {
                roomHandle.Completed += loadedRoom => SpawnChapter (loadedRoom.Result);
            }
        }

        private void SpawnChapter (GameObject room)
        {
            Debug.Log ("Spawn Chapter");
            Runner.Spawn (room.GetComponent<NetworkObject> ());
        }```

What is weird, that first debug in InitializeGame gets called once, but the one in SpawnChapter is called twice. What can be the reasone that Completed gets invoked twice? Guys from Fusion say that it's not on their side.

Is there a way to control the internal names of asset bundles generated by Addressable builds? It seems like it creates big, crazy long, obtuse, unique hash names, correct?

lunar shard
#

here's an example of what I am talking about

unknown.png
#

as far as I can tell, Addressables auto generates these without any documentation as to how or what the names mean

hexed shell
lunar shard
#

sadly no, those set the external names of asset bundles

#

basically only the filenames

#

internally, asset bundles have different names

lunar shard
#

here's an example using the Asset Bundle Browsing tool to read the internal data of an Asset Bundle made by addressables

unknown.png
#

it gives the internal Name field a hash (which is different than the hash Addressables can append to the filename), and then the Dependency names are also different from both the Name field hashes and also generated somehow and for some reason.

#

assets_example_a7001bddbca3a53b33baf95c5ba52b07.bundle this is the filename of the assetbundle, and it is what Bundle Naming Mode controls.

#

I am sure there is code somewhere in the Addressables source code for controlling this, it just appears to not be exposed to me as a user unfortunately. So, I'll have to write my own custom build script or go hunting for it to modify it I suppose.

It's kinda ridiculous that Addressables doesn't already expose this functionality lol

Hey guys, for a solo dev working on a medium sized game, is it worth investing time to work with addressables when the game is at 20% progress or later on at 60-80%?

I am beginning to understand the value, but i think it adds way more friction at the early stages.

I need to create WebGL and Standalone builds which use Addressables. However, the standalone builds need to load local bundles and WebGL needs to load remote only. How would you do this? The build/load paths are set per group, but you can’t have the same assets in two different groups…

Hmmm, is it bad practice to set the remote build and load paths in the profile to the local paths? That should solve this issue, but it seems like this might not be the intended use

How can I config unity addressable in difference machine can download same build file?

hot shadow
#

Why addressable not support asset bundle file that build from difference "addressable_content_state.bin" on remote mode?
I mean same unity project but difference project folder location.

I'm getting the error "Exception: Attempting to use an invalid operation handle"
` public async Task<Sprite> Load()
{
_handle = assetReference.LoadAssetAsync<Sprite[]>();
_value = await _handle.Task;

  return Value;
}`
#

The other part is that calls load is:
public async Task SetSprite(Sprite3DResource sprite) { _sprite.Release(); _sprite = sprite; _renderer.sprite = await _sprite.Load(); }

#

any clue on what I'm doing wrong?

#

to make it clear, it gives the error as soon as the game is on, because it has:
private async Task OnEnable() {await SetSprite(_sprite);}

#

private void OnDisable() {_sprite.Release();}

#

Release code is as follows:
public void Release() { if (_handle.IsValid()) {Addressables.Release<Sprite[]>(_handle);} }

minor tinsel
#

My gut tells me that the first one will be faster, because the second one will always have to resolve the instance in some way even if it caches it

#

Whereas with option 1, you resolve the instance once and have it right there

cursive mulch
minor tinsel
#

I might've missed something while looking at the internal logic

#

I'm not familiar with remote loads so I wouldn't be surprised if that were the case

#

Looks like the only other thing it does is modify the path when in the editor

#

try changing

#if UNITY_EDITOR
if (bundle)
    yield return SceneManager.LoadSceneAsync(scenePath, parameters);
else
    yield return EditorSceneManager.LoadSceneAsyncInPlayMode(scenePath, parameters);
#else

to

#if UNITY_EDITOR
if (bundle)
    yield return SceneManager.LoadSceneAsync(scenePath, parameters);
else
{
    if (!scenePath.ToLower().StartsWith("assets/") && !scenePath.ToLower().StartsWith("packages/"))
        scenePath = "Assets/" + scenePath;

    if (scenePath.LastIndexOf(".unity") == -1)
        scenePath += ".unity";

    yield return EditorSceneManager.LoadSceneAsyncInPlayMode(scenePath, parameters);
}
#else
#

Aside from that, everything appears to be identical to how Addressables.LoadSceneAsync works

cursive mulch
#

oh my mistake for making it clear, I tested on build version, not editor version. Editor works fine for me.

sharp crow
#

how can I get a list of keys for assets with a certain label

#

I can LoadAssetsAsync with "MyLabel" but then I only have prefabs without the original key they had

#

var loadResourceLocations = Addressables.LoadResourceLocationsAsync(new[] { "MyLabel" }, typeof(GameObject)); does not return anything

#

hmm weird. it works now

#

not working: var loadResourceLocations = Addressables.LoadResourceLocationsAsync(new[] { "MyLabel" }, null);
working: var foo = Addressables.LoadResourceLocationsAsync("MyLabel", null);

#

any idea why?

#

it also returns 5 identical primarykeys per entry

minor tinsel
#

It's possible maybe it needs a bundle and it's not being loaded or something

cursive mulch
minor tinsel
#

Hmm, what if you log the scene path, does it look valid?

#

Could also enable this part in a build and log if each bundle loads correctly:

#if UNITY_EDITOR
    foreach (IAssetBundleResource resource in depHandle.Result)
    {
        if (resource != null && resource.GetBundle() != null)
        {
            bundle = true;
            break;
        }
    }
#endif
#

As far as I can tell this should be functionally identical to Addressables.LoadSceneAsync so there must be something subtle I'm missing

cursive mulch
#

The log looks valid

#

I try a build with local load option and it works fine btw. Just something wrong with remote

minor tinsel
#

Yeah, that is really strange

#

And Addressbles.LoadSceneAsync works perfectly fine with remote?

#

Also which version of the addressables package are you using? Maybe I was porting code from an incompatible version or something

#

Gotta step away for a bit to get some stuff done IRL, but if you'd like I'll ping you when I get back to investigate further

@cursive mulch Interesting, I made that function by reading version 1.19.17's code

#

So maybe 1.18.19 has differences

minor tinsel
#

Hmm, appears to be the same, though I suppose there is one thing I missed when translating the code

#

I noticed that the code still iterates over the bundles and calls GetAssetBundle even in builds, so maybe that actually loads them

We have two layers of cognition on Assets: one layer comes from Unity’s default project directory Assets, and the other layer comes from Unity’s packaging system AssetBundles. Therefore, we will normalize from these two aspects to understand what Unity’s Assets are.

Addressable Chapter 1: Assets - Unity Asset Reference - UWA Blog

This article is the first chapter of the Addressable series.    What are Assets? Generally speaking, we have two layers of cognition on Assets: one layer comes from Unity's default project directory Assets, and the other layer comes from Unity's packaging system AssetBundles. Therefore, we will normalize from these two…

Those topics are easy for your guys to check out the issue you probably rencounter in the future.

Hi, these addressables are a bit confusing. Hoping someone can help me out with my understanding! I have some questions about this bit of code:

{
    for(int i = 0; i < 10; i++)
    {
        string key = "Prefab";
        //preload to gain access to the handle.Result, so that we can supply the rotation of the source prefab to the instantiated prefab
        var preLoadHandle = Addressables.LoadAssetAsync<GameObject>(key);
        yield return preLoadHandle;
        if(preLoadHandle.Status == AsyncOperationStatus.Failed)
        {
            Addressables.Release(preLoadHandle);
            throw new Exception("Addressable not found");
        }

        var instantiateHandle = Addressables.InstantiateAsync(key, preLoadHandle.Result.transform.position, preLoadHandle.Result.transform.rotation);
        //result should be immediately available
        instantiatedPrefabs[i] = instantiateHandle.Result;
        Addressables.Release(preLoadHandle);
    }
}```
#

  1. Do you see anything wrong with this code? I am using LoadAssetAysnc together with InstantiateAsync, mainly because I need to access the rotation and position values of the underlying prefab asset when instantiating the game object that will be used in the scene.

  2. I believe the ref count should be 2 after the InstantiateAsync call, then 1 after the first Release call. Is that correct?

  3. Does the Release call release the underlying asset bundle, or because the ref count is still at 1, the asset remains in memory?

  4. If my understanding of the ref count is correct, then subsequent LoadAssetAsync calls should not actually load in a new asset bundle, but instead detect that the asset is already loaded and use that for its Result. Is that correct?

  5. All InstantiateAsync calls should use the asset loaded with the first LoadAssetAsync call, right?

  6. Let's ignore that this is a loop. Instead, imagine that the subsequent calls to LoadAssetAsync and InstantiateAsync occur at a later time, but it's always true that at least one instance of Prefab still exist in the scene. These calls will not force a new asset bundle to be loaded into memory, correct?

#

Okay, so perhaps I different question then.

If I want to load multiple addressable assets at the same time, what is the best way?

  1. Individual calls to LoadAssetAsync and I track the load operations manually.
  2. Using LoadAssetsAsync
  3. Using CreateGenericGroupOperation

Are 2 and 3 simply convenience features that allow you to track group progress as a whole? Or is there some efficiency advantage to them? I am concerned that those two methods will cause garbage generation due to the list that is returned. I also don't like that the whole operation seems to fail if any one asset fails to be downloaded/found. So I would lean towards 1, but don't know if it is inefficient to use that method.

Why when editing prefab quite slow than normal on addressables asset folder?

sudden mesa
#

Is it normal that the GetDownloadStatus().Percent function always returns 0 when trying to load addressables from local folders ?

#

Unity 2021.2.14f with Addressables 1.19.19

#

I wanted to show the download progress but it keeps returns 0 in the yield loop.

mild flax
#

Yes it’s 0 because it is essentially “already downloaded”. Might be quite difficult to show an accurate progress bar - I’m not sure if there’s any other api call for monitoring the progress of eg the decompression for large bundles.

sudden mesa
#

Ok, I see. I'll just show a loading icon then without the actual progress, that'll be enough. Is this information written on the documentation page regarding local content returning 0? I don't remember seeing that. It might be worth mentioning.

Hi everybody! My first post, so I hope I'm not breaking any rules etc. by asking this question. I want to load some songs at runtime from a folder on my local drive. ( not inside unity assets folder). Would addressables be the correct way to go about this. I assume asset bundles wouldn't work. I've managed to obtain some data outside of the assets folder by getting URLs via JSON file and managed to get 1 song only via UnityWebRequestMultimedia.GetAudioClip too. The problem with the things I've tried so far have limited me to single files,audio,videos only. As mentioned I'm wanting to include several songs at runtime from outside of unity assets folder. So are addressables the correct way to go about this or is there other options available to me?

wooden moss
#

be aware, last time i checked, you cannot load .mp3 at runtime because of licencing

rich quarry
#

@charred osprey do you mean that you want to be able to load external music into the game

#

you would be using file operations in that case, and would need to convert them into an audio clip

#

looks like this SO question uses WWW to accomplish this:

#

but WWW is fairly old, so perhaps see if there's a way to do it using UnityWebRequest

wooden moss
#

it is pretty much the same with UWR but like i said, you prob won't be able to use .mp3 because licencing (and that's built into unity)

rich quarry
#

the SO also indicates this

wooden moss
#

but maybe the .mp3 licensing ran out since then

rich quarry
#

SO says it works with mp3

wooden moss
#

haven't checked

rich quarry
#

yah I believe you

#

just noting it seems to be working at least as of 2019.3

wooden moss
#

yeah, last time i implemented it was with 2017 or 2018 i think but .ogg is better anyway XD

rich quarry
#

ogg 4 lyfe

#

if you're loading external music tho you may not have a choice 😄

wooden moss
#

and yeah he stated previously that .mp3 doesn't work on windows. but apparently that ran out now. hooray

rich quarry
#

yay

wooden moss
rich quarry
#

haha

#

"This program only supports ogg because f u"

wooden moss
#

not really. because licensing

#

XD

#

good to know

rich quarry
#

what is taking its place?

wooden moss

AAC and others

@wooden moss Streaming Assets Folder. I'll look into this. I wasn't aware of that option. So .mp3s are legal now i assume. Basically i've made a set of DJ turntables to mix with and the DJs will likely have .mp3 files in their playlist. Getting them to convert their files would likely be problematic because people don't like taking extra steps. 😄

wooden moss
charred osprey

that sounds the ideal approach for me. Cheers Mindstyler. I'll look into that and try dig some info about using streaming assets folder instead
