[charred briar]

Sounds like a memory leak of sorts to me

[craggy ruin]

Yes, and I just tested a previous build of mine and that worked too as you said. So ig it’s something with Unity 🤷‍♂️

Or memory

[sterile burrow]

its iOS having extreme restrictions on RAM it seems

try and build your game on a lower resolution

that seems to fix it for us

at least atm

[stoic tinsel]

Is there a way for Unity 6 to put the “we don’t run on mobile” check back? References to where it was in the 2022 template might be enough.

My game is webgpu only so doesn’t work. At least on iOS.

And also has a LOT of code which sometimes seems to make it die on load with “streaming compilation failed”

[astral wave]

The memory usage you see is not exactly correct on safari memory profiler. If you want to see exact memory usage, connect unity memory profiler to your build and use it. It ill not only show exactly what uses most memory, but also exact numbers which causes problems.
https://docs.unity3d.com/Packages/com.unity.memoryprofiler@1.1/manual/index.html

[astral wave]

Also please have in mind the you should test on platform you have problems. One of main reasons is textures compression. For example if you test it on PC and your project is set to DXT format, memory usage will be lower than on iOS, as on iOS it will be decoded to RGBA, which is 4 times bigger format. This is extremely noticeable on VRAM, but I found that images size in memory (if not unloaded) can differ as well. I might be wrong here, but from my experience correct compression helped a lot with issues like that.

[frank hound]

It looks like your server isnt setup for brotli compression. If you are just testing on your pc using the standard build method, change your PlayerSetttings > Player > Publushing > Compression Format to disabled. Otherwise look into configuring the server for Brotli.

Also the setting above that will come in usefull at times to debug when set to Full with Stacktrace.

publushing... 😄 I may have been guilty of this b4

[obtuse loom]

Is there any way of exporting the localization assets... "raw" into the build? 🤔
I want to change the localization without having to rebuild the game 🤔
(I can probably do it by hand, with a json, but I lose the entire unity localization tools 🥲 )

[sweet oriole]

Would rebuilding addressables be ok? I believe you can ship them as addressable assets.

Looks like you can do this without Addressables through a TableProvider https://docs.unity3d.com/Packages/com.unity.localization@1.5/api/UnityEngine.Localization.Settings.ITableProvider.html

[obtuse loom]

ohhhh, that could be exactly what I want 👀

[polar spade]

when i try to open my game in firefox this pops up

[astral wave]

I think red text explains it better than anyone could. you cannot Just open index html, you actually need to host it on server (you can have it localy). Or just press Build and Run on Unity, it will work then, as it creates temporary server to run at.

[haughty lynx]

Hey! I'm really struggling to understand the server configurations for brotli or gzip, my app runs without problems without compression, but I can't find any info for the content headers when hosting on something else than Nginx, Apache, and IIS servers (from the docs)

[arctic rose]

What is it running on then?

[haughty lynx]

Render static site, also tried Netlify

[arctic rose]

You'll have to look up how to set up headers in those services and then add the necessary ones

It might not be possible in all services

[haughty lynx]

Yeah I tried to look it up but I don't think it's possible, what do people usually use to host webgl (own website not like itch.io)

[arctic rose]

I think the most common ones are itch.io for hobbyists and studios have their own server infrastructure

I know Firebase Hosting lets you set up the headers but it's a more involved setup compared to Netlify and similar

[sweet oriole]

You can control content headers (among other things) through netlify.toml. Documentation is on their site and people have posted templates for Unity content.

[haughty lynx]

I came across it, but the netlify.toml didn't change anything, still had the errors concerning content headers
this was the template: https://www.ankursheel.com/blog/host-compressed-unity-webgl-game-on-netlify, also tried one from github

[sweet oriole]

I believe it says something about rules being applied when you deploy the site if it's able to parse the file

[haughty lynx]

Sorry I'm not sure I understand what you mean, is there a way to check if the file is parsed?

The docs of netlify just says that the nelify.toml file must be in the root of the project, so alongside the Build, StramingAssets and other webgl files, and the format of the [headers] corresponds to their docs so I don't really know if it's a step I missed or it just doesn't work

Also when inspecting the network tab the files does not have the Content-Header: br (they do appear with http:// instead of https:// tho, but the error remains)

[sweet oriole]

Yea I recall seeing the output changing when looking at the deployment status. It went from just showing something about the files to also mentioning amount of rules being applied.

Haven't done this in a little while, so I don't remember specifics.

[haughty lynx]

I see thanks, tried everything couldn't get it to work so I'll just keep that way for now and try the others ways.
Another quick question concerning webgl, when visiting my app on mobile the quality is horrible, but when I go into the web browser settings a click "request desktop device" quality is perfect (performances not affected), is there a way to have this quality by default?

edit: I could determine that it's because of the resolution, but I cannot find a way to adjust it as in webgl there is nothing in Screen.resolutions

edit 2: ended up fixing it with the display ratio within the index.html file

[stoic tinsel]

Just installed ios18 to test. Looks like still no WebGPU support?

[tardy junco]

Hi everyone, what do think is better to build the game like Seafight or Legend Pirates?
Unity or other such as Phaser, Threejs, Babylon, godot, etc...
Hope to hear from you.

[astral wave]

ios dont have webgpu even on beta versions.. I wouldn't expect it to come anytime soon.

[astral wave]

All depends.

Are you targeting only web platform? or you targeting multiple platforms. If multiple platforms then Unity is amazing choice.
Are you going to use assets to speed up your development? Asset store have tons of out of the box solutions that you can use, Unity is good choice again.
Do you ant to work with editor with convenient features and a lot of features? Unity is great choice then.

Do you focus purely on performance and to run as many mobile devices as possible? Chose Playcanvas or others web based solutions.
Want project to be as small as possible? once again, maybe Unity is not for that.

As I said it depends on what you aiming for. You can create Seafight or Legend pirate on all engines you mentioned. I personally would choose Unity as I like working on Unity.

[sour arrow]

He was asking between unity,godot,babylon and perhaps unreal engine i think

[astral wave]

I understood that etc means: or any other engine. But my answer doesn't change, it all depends on what he needs. ThreeJS, babylon, Playcanvas is great for Web deployment, performance and project size is extremely good. But they lack in editor and features list. Unreal? I am not even sure worth to create Web application for it, it is just too demanding and for UE5, there is no official support if I remember correctly. Godot, it is great engine, and from gamejams information it replaced big part of Unity project (that mean webgl works, but how well, I don't know). And well Unity have problems with project size and memory limitations on older mobile devices is bit harder to optimize, but have very convenient development process.
The games he provided as examples can be made by all engines, what he targets is what important. So I cannot say: USE GODOT IT IS THE BEST, or something else. All have advantages and flaws.

[sour arrow]

No engine is as versatile as unity, so just use unity?

[tardy junco]

I'm going to build for web platform only. Unity's loading speed is slow at the first time. Currently, seafight is built with unity and not smooth as I think. even my pc is pretty good to play such the game.
anyhow thank you for the advice.

[tardy junco]

I thought so like you Godot before.

[astral wave]

I like Godot idea, and I think it ill grow to great engine. I am just not sure its current possibilities. About loading speeds, in most cases is more about downloading assets than actually loading. So you really need to be carefull with what you add in your project and use correct compression. Use addressables to load only things that you currently need, for example initial load to load only main menu scene, and load resources for gameplay only when you need it.

Also there are ways to strip Unity engine parts that you don't actually need in order to minimize the size and increase loading speeds. But that requires quite a lot of work.
https://github.com/JohannesDeml/UnityWebGL-LoadingTest

[sweet oriole]

I wouldn't necessarily put too much weight on the experience of old flash games converted to (or emulated in) Unity without knowing some technical details of the process.

[hollow light]

Hey there. My boss needs a game exported in webgl. But he wants a javascript that can be changed even after the build. One that links to functions inside the build game. There seem to be many means of doing so. Any recommendations? I'm completely new to webgl.

[arctic rose]

Pick one that works and use that? This isn't the kind of choice that would have far reaching repercussions

[charred briar]

Assuming you go down the Unity path

Is anyone able to build with audio on Linux?

Windows builds web fine with audio

[cerulean spruce]

I am hosting a game server on multiplay which is using Mirror's simple web transport
my client is able to send request to the server and server receives it but after that the server restarts for some reason. Same setup is working locally but not on the hosted server.

One problem that i think could be cause problem is that i dont have ssl certificates setup locally, do i need to generate ssl certificate and set them up for wss connection? if not then what could be the problem?

[rough spire]

Hello everybody

I just have a small question

How do I embed my unity webgl build to my live website?

[charred briar]

Any way you normally upload files to your website. It depends on the site.

[serene quarry]

Has anyone compared the performance of WebGPU and WebGL on Unity 6 preview (0.20f1)? I tested a scene with over 10000 draw calls and enabled WebGPU support in Chrome, but it seems that there isn't much difference between the two

[hollow light]

How do you guys use json to send payloads?

[void canopy]

why won't webGL recognise up and down inputs from the joystick but it does from the dpad?

[hollow light]

hey there. There is a mistake in this part, but I can't figure out what it is. Sitting on this for a few hours now...

    {
        let s = UTF8ToString(payload);
        let bufferSize = lengthBytesUTF8(s) + 1;
        let buffer = _malloc(bufferSize);
        stringToUTF8(s, buffer, bufferSize);

        return buffer;
    },```

[sonic olive]

Hello everyone, I’ve tried just about everything to solve this problem but can’t do it. I’m very new to coding and this is my first project. I got this from a tutorial for 3d but my game is 2d. The problem is when i remove the item from my inventory it wont let me pick it up. it first I thought it was because it was a clone but the way he did it it uses a string to identify it. The clones still had the string saved so I don't know whats happening. Here’s a link to the “game” https://github.com/Kalani12345/2D-game

[arctic rose]

You'll have to give a lot more details

[arctic rose]

Does it happen specifically in WebGL only or why did you ask in this channel?

[hollow light]

This is webgl | Unity 2022.3
I never tried it in any other context.
When I import it like this in my c#-script:

private static extern string testJsonExtern(string payload);```
I get this error:

This is the entire jslib-script for more context:
```mergeInto(LibraryManager.library, {
    setHighscore: function(payload)
    {
        let s = UTF8ToString(payload);
        s= UnityBridgeProfile.setHighscore(payload);
    },

    retrieveHighscore: function() 
    {        
        let payload = UnityBridgeProfile.retrieveHighscore();

        let bufferSize = lengthBytesUTF8(payload) + 1;
        let buffer = _malloc(bufferSize);
        stringToUTF8(payload, buffer, bufferSize);

        return buffer;
    },

    testJsonExtern: function(payload)
    {
        let s = UTF8ToString(payload);
        let bufferSize = lengthBytesUTF8(s) + 1;
        let buffer = _malloc(bufferSize);
        stringToUTF8(s, buffer, bufferSize);

        return buffer;
    },
});```

[arctic rose]

Is the jslib in a file with a .jslib extension and placed in Assets?

[hollow light]

Yup. The other functions work as well.

If i don't import testJsonExtern, that is

[arctic rose]

Did you save the file?

[hollow light]

of course.

[arctic rose]

Doesn't really make sense why the two other functions would work but this one not. Does it work if you change the name? Maybe "extern" messes it up

[hollow light]

Maybe.... Let me try that

... I found the error. I uploaded the project to github for my coworkes, but still edited the old file outside my the branch... God dammit.

It works... Yaaay... 😐

[sonic olive]

Sorry I don’t use dicord a lot and didn’t notice

[radiant anchor]

Hello i want to ask something im not sure where to ask but here is the question im using is AWSSDK and is the pre-signed-url feature is not working in WebGL? since after few debug the error always right there. Oh btw its works perfectly in editor its only doesnt works in WebGL build, Thanks

[astral wave]

does AWSSDK even support webgl? as if plugins is not in JS, it won't really work on Webgl. You should look if there is something like: Javascript SDKs of AWS

you can read more here https://discussions.unity.com/t/aws-sdk-for-webgl/917538/6

[radiant anchor]

oh my god right its not support WebGL

if using Unity Web Request does that mean the server need to be publicly accessible so unity can also get data from the server?

[arctic rose]

Depends what you mean by publicly accessible

obviously if you want to make a request to a server then you need some kind of access there

[astral wave]

WebRequest is unity specific html requests, it just don't use some specific libraries and uses Unity libraries instead. Technicly if you could find all requests in that plugin and replace to UnityWeb request it might even work. But I wouldn't suggest to do it, as there might be other problems, like threading, which will still won't work on webgl.

[radiant anchor]

yes so what i mean is i want my server is private so no one can access the data via url, but if unity is the one that request it then unity can still get the data, is that possible? im not to sure if what im saying is make sense xD

[arctic rose]

Not really

How can you access the data then?

[astral wave]

you can block incomming data. But only accept responses to your requests. It is possible. but that is not unity server problem it is server machine setup it self

[radiant anchor]

ah yes i have problem with threading previously

[radiant anchor]

i dont know hehe

[arctic rose]

Well figure that part out first. Right now you're basically asking "there's no way to access data on my server. Can Unity get the data from that server?"

[radiant anchor]

i see so if we want to do that, thats need to be something that processed by the server not unity

[radiant anchor]

xD

[astral wave]

I would not think too much about it first. anyways you will want your unity server to be accessible by clients anyways. you can always block access later

[arctic rose]

Also note that it's impossble to set it up so that only your game can access the server and nothing else

[radiant anchor]

yea thats probably true

[radiant anchor]

i see okay

Thank you all i will ask again about this later after i have more question, Once again Thank you

[fathom patrol]

I got this issue when the scene changes. (itch.io)

[cinder furnace]

Hey, I've been getting this error/outcome inside a build only (it works fine in the editor) when calling a .jslib that awaits for the outcome of a popup, any thoughts on why it sees the popup window as closed right away even though it's not?

[graceful helm]

does unity webgpu work with ecs? or it’s mono behaviour only?

[plush pawn]

Hi guys

How do I get and output this data to Unity from Telegram?

[plush pawn]

Up

[plush pawn]

help guys

[astral wave]

I don't know what Telegram JS SDK will let you access, but if you can access that information from Telgram API to JS then you can pass data from JS to WebGL following this:
https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html

It is not secure tho in My opinion.

Another way is to use WebRequest and talk with your on Telegram API.

But both requires good knowledge of Telegram, which is bit hard 😦

[amber ginkgo]

hey, anyone knows the trick with CancellationTokenSource in webgl builds?

I call a _cts?.Cancel(false) where false explicitly states not to throw an exception, but in webgl builds it throws anyway

ObjectDisposedException: The CancellationTokenSource has been disposed.
  at System.Threading.CancellationTokenSource.ThrowObjectDisposedException () [0x00000] in <00000000000000000000000000000000>:0 
  at System.Threading.CancellationTokenSource.ThrowIfDisposed () [0x00000] in <00000000000000000000000000000000>:0 
  at System.Threading.CancellationTokenSource.Cancel (System.Boolean throwOnFirstException) [0x00000] in <00000000000000000000000000000000>:0 

[plush pawn]

I managed to do this without the SDK's help

[astral wave]

Webgl don't support Threading. Code or asset you are using will not work on Webgl.

[amber ginkgo]

but cancellationtokenSource doesn't use threading

does it?

afaik it uses a simple data model where the data is managed and shared between asynchronous states. so any Task or async voids can access that data

[astral wave]

Webgl dont support tasks either. If you want use them you will need to use UniTask library for that.

[amber ginkgo]

nah that's not correct. Task isn't multi-threaded by its nature. It's well supported in WebGL

just don't use functions that use different threads like Task.Delay. but others like Task.Yield() are fine. I've used them for years with no problem

[astral wave]

Sorry, I just don't count it working when big part of library doesn't work on WebGL. So I wouldn't be surprised if that part is dependable on something that does not support webgl. What you can try just put part of code in try/catch logic and handle error handling depending on platform. So you will end without errors?

[amber ginkgo]

yeah it seems like I have to build my own cancellationtoken feature. looked up online and there's zero references on this anywhere, kind of surprising

🥲‌

[astral wave]

If project webgl only, I really suggest using UniTask, it's cancelation logic is identical and it works on webgl without problems for sure.

[amber ginkgo]

thanks for the tip, yeah I looked into that project, it adds unnecessary overhead tbh. the system is already simple to create. it's already done actually, created SafeCancellationTokenSource and SafeCancellationToken under the same namespace as the normal ones, and from there it was a simple replace-all in Rider

[solar hound]

Render texture not working on WebGL build, there is only a black part at the bottom-left corner showing instead of the camera render, In editor Render texture is working just fine. how to fix this issue on webgl?

[plush pawn]

hi guys

How do I connect Firebase to the game? WEBGL

[plush pawn]

help guys

[amber ginkgo]

Google WebGLFirebase and open the github repo. It's what I use and it works.

[plush pawn]

https://github.com/rotolonico/FirebaseWebGL ??

[amber ginkgo]

that's the one

[plush pawn]

Is Unity CLoud good for this?

[amber ginkgo]

I haven't used it

[astral wave]

render textures works on webgl for sure. But you can have here several problems. More common one would be solved if you would manually refresh texture after you are sure that camera is rendered something in it. (pretty much it thinks that there is no new data and don't render anything.)
other problems could be texture format or settings, you can try playing with that.

[solar hound]

@astral wave Thanks for the help, can you help me how to refresh the texture at runtime? I have tried this code but still not working on Web void Refresh() { SecondCamera.Render(); Graphics.Blit(SecondCamera.activeTexture, renderTexture); }

[astral wave]

for testing you can try just add button that enables and disables your texture, if after disabling and enabling it again it shows correct image, then you will know that is the culprit.
Depending on where you rendering, some of elements have dirty feature: ImageRenderer.SetAllDirty();

This is texture settings that most definettly works on webgl. I am sure most of it does work, but just in case.

[solar hound]

@astral wave Hi, I did what you suggested by disabling and enabling RawImage and setting the value of RenderTexture the same as your image but still no render appears on the Web build(It works perfectly on Editor). you can see my code and RenderTexture setup. Thanks!

[astral wave]

hmmm, try reinialise your code on button click, the one that enables camera and passes texture to the element. Can you share you texture settings and initialisation code where you enable camera and set target to the texture?

[solar hound]

@astral wave I set RenderTexture to the camera in inspector not within the code

[astral wave]

hmmmmmmmm, what else could it be. Could you try something:
-create 3D cube and put the texture on it. Then we will know if that is UI problem or other problem. (as UI sometimes dont like to be refreshed correctly.)

[solar hound]

@astral wave 😇 Its work on cube but not on RawImage, I use RawImage because i need it in UI

[astral wave]

so you setup is like this right?:
What shader does your meterial use?

[solar hound]

@astral wave URP Lit

[astral wave]

you will need to change URP to different shader, UI/Default or something. I am building right now webgl build to test, but shader is incorrect for sure.

[solar hound]

@astral wave 🤩 Its Work! Thank you so much

[astral wave]

Glad to hear it worked 🙂 good luck

[solar hound]

@astral wave You save my day thanks!🙂

[amber ginkgo]

Hey. Anyone used unity 6 webgl yet? Any particular bugs?

[gentle epoch]

i have a question
so if i publish my unity game with webgl
and after that i make changes to the game
the webgl game will be automaticaly updated?

[sweet oriole]

Players will update when they refresh the page, but you would still need to upload builds to your web server.

[pastel bobcat]

I'm suddenly getting this error for unity webGL. I've tried turning off toggling decompression fallback made it work for a day then the new build got the error again.
Worth noting that I'm getting the error on my old itch webgl games that used to work correcly. did itch change something?

[pastel bobcat]

please I need help. I need to get the webgl version running. I don't know if this is only happening to me. There is no reason for old working builds to fail like this. But they are failing even if I switch browsers or even devices

[solar hound]

@pastel bobcat select "Full With Stacktrace" and see the full log on the browser for error log

[loud plaza]

How are the build sizes with Unity6? Are they viable for simple 2D games on platforms like Poki, YandexGames etc?

[sweet oriole]

You can find reasonable baseline numbers here https://github.com/JohannesDeml/UnityWebGL-LoadingTest

[cinder furnace]

Anyone knows?

Still havent' found a solution

[low oasis]

In Unity 2022.3.20 version webgl build, a click sound is heard every time the audio loop repeats. How can I solve this?

anyone else having general audio issues

[random talon]

I have a PNG hosted on amazon cloud and I get it at runtime via a UnityWebReqestTexture.GetTexture(url)

It works fine on Editor

but when I load the webgl game on website like Itch.io I get CORS error

is it due to the site policies or Amazon security policies?

[arctic rose]

Amazon

[random talon]

Just to be sure here's the error I get

Access to fetch at 'https://xyz.cloudfront.net/image.png' from origin 'https://html-classic.itch.zone' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

[arctic rose]

Yes, the server must send the appropriate CORS headers with the image

[amber ginkgo]

hi.
we have deployed an upgrade to our web page which is a webapp, PWA and all that. it's a Unity webgl build, if that's important.
iOS browsers Safari and Chrome keep using the old JavaScript files from before the upgrade, even in incognito. is this a common iOS thing? are there any solutions for this?
I'm sending no especial header, but it's been more than 1 week since then now, and iOS browser still use the old version...

[solar hound]

Has anyone encountered this issue while building for the web It takes 20 to 25 minutes to make, and progress stops at linking build.js (wasm) for 20 minutes. Is there any solution for this? I am using Unity 6 LTS and the same issue occurs on 2022 LTS

[amber ginkgo]

Well that's the long part so it's normal to take long. 25 mins? That depends on your hardware

[solar hound]

@amber ginkgo Previously on the same hardware and the same project, it takes 1 or fewer minutes to build.

[amber ginkgo]

Are you sure? Webgl takes more than that for an empty project on a decent hardware

[random talon]

is webgpu already available on unity6?

[hazy mural]

I think it is but you need to enable it. I'm looking up if the steps are available somewhere.

ok thanks

[honest swift]

I have a build of the unity webgl game, but when I uploaded it to the hosting, it stopped loading after the initial download window appeared,what to do?

[next kraken]

Does webgl build support URP decal projectors? Desktop build looks fine but can't see the decals on webgl.

[frozen quarry]

Hey guys. i'm doing a small game in unity for a sort of game jam here locally, and they're asking us to make it playable on web, on itch.io. is there any limitations to this? Or can I just make any game use the extension and it'll be playable on web? Just a short game 10-15 mins, low poly.

I heard there was a certain build profile or something

[sweet oriole]

Check browser's console for potential details

[sweet oriole]

Might need to change decal rendering technique https://docs.unity3d.com/6000.0/Documentation/Manual/urp/renderer-feature-decal-reference.html

[sweet oriole]

Just changing the build platform is enough. Make sure you have the module installed (can be added through Unity Hub if not). Things work within the limitations of WebGL, WebAudio, web input, no threading and generally limited access to platform features, but this generally just works for most games. https://docs.unity3d.com/6000.0/Documentation/Manual/webgl-develop.html

Just make sure to test early in case you do happen to bump into something.

[next kraken]

Thanks. It was set to automatic (so depending on build) but I'll try each one out.

[woeful matrix]

how do you guys normally debug webgl builds? I get an error in the chrome browser development console, but it looks gibberish.

do you guys always enable exception with full-stacktrace for a webgl build?

[obsidian cliff]

Depends on the Unity version, you can make the names of functions more readable.

I think development build does it. But sometimes you want this to debug release build.

You can use
PlayerSettings.WebGL.emscriptenArgs = "--profiling-funcs";
Or edit the emscriptenArgs on the projectsettings.asset file.

More info here:
https://medium.com/@depanther/unity-webgl-secrets-b6ddf214f1fd

[woeful matrix]

Thanks. didnt know about --profiling-funcs . will give it a try

[coarse acorn]

I have a problem with WebGL not using the camera's solid background color in fullscreen mode: (please ignore terrible UI scaling, thats a separate issue)

What am I doing wrong?

[pine imp]

I have a strange issue where certain animations are playing at a much slower rate in the WebGL build of the game than they do in-engine. Any ideas where I should start looking? The overall framerate is still normal, just some enemies' animations are playing at a lower framerate for some reason.

[pliant magnet]

Anyone have the issue of a game not updating on the website after making changes despite, doing a clean build of the game, replacing files, cleaning and rebuilding the app? lol

The game works with changes and everything if I just do a build & run as well as in the unity client itself, but i'm having a hard time figuring this out lol

[astral wave]

On website you need to deal with cache. If it for testing purposes, just do hard page reload or open project in incognito mode. For production you might want add versioning into acount. The easiest way is to have files with new unique name, then it wont be cached. Another solution dpends on your websit provider, most of them lets you clear cache manually.

[sweet oriole]

"Name files as hashes" option in web player settings handles renaming Unity files for you

[woeful matrix]

so it seems websocket-sharp doesnt really work with webgl, whats a good alternative library for websocket networking?

[sweet oriole]

Any Unity supporting websocket transport that comes with jslib files will probably work. https://github.com/James-Frowen/SimpleWebTransport is used by Mirror and Mirage.

[random talon]

is it just me or Unity 6 webgl is very unstable?

I've tried to translate my Unity 2022.3 project into Unity 6 either by changing editor and by creatimg a blank project and reimport all but the I got stuck on webgl loading screen with no errors

[solid river]

would love your opinion on this, atm i'm on 2022.3.8 and it's very stable, what version were you on before?

[random talon]

as I said 2022.3 maybe .22 dont remember but I don't think that minor version will make the difference

Maybe its some dll I'm using but the console isn't giving me any useful info about the problems I'm having

and that is just with using webgl2.0, I haven't even tried WebGpu yet

[solid river]

hehehe i think it does 🙂 saying that as a person who released 2-3 games and spent over 7-8 years in unity

[random talon]

well then just duplicate your and let me know cause I'm curious

I expected that upgrade to be way smoother

even cause my project isnt that big

[solid river]

WebGPU is also the reason why i want to try and switch, but i de-installed when my fonts were blurry in the editor. I can change the text sharpness in the settings, but it's either too sharp or not sharp enough somehow

[random talon]

I got disappointed to know its still in preview honestly

they pushed it so much as Unity6 feature but officialiy is not completed yet

[solid river]

I see

yeah me too, i'm creating a mp shooter btw with NGO

nothing too fancy yet, just a web shooter

i read it's also a part of 2023.

https://discussions.unity.com/t/early-access-to-the-new-webgpu-backend/933493/62

lots of people with bugs tho xD

but maybe interesting to checkout soem latest messages, some people do have it working, also some talk about unity6

[astral wave]

when you were copying files in new project, did you copy Library folder as well. Its common that library folder cause problems on version upgrading. You could try deleting it, and then opening project again in version you want and let Unity regenerate it. I only used unity 6 with small webgl test projects, but have not find any problems yet.

[random talon]

I did not, I created a new project from 0 and imported the scene as unitypackage with its dependencies

[astral wave]

could it be some dependencies needs to be updated first? I mean some older packages might need to be updated if you using a lot o them. Sorry hard to tell without knowing project.

[random talon]

Im 100% sure its all up an running, in fact it all works in editor, but when playing on webgl the website literally freezes when the loading bar reaches the 100%

and I have no info in the console so I really dont understand what is going on

[astral wave]

have you tried loading in dev mode? and connecting profiler to it?

[random talon]

the only thing that I still need to do is connect the editor console to the build running

but I got quite demotivated at least for now since I'm seeing that a lot of WebGL devs are complaining about problems regarding the Unity6 project import

[astral wave]

I know it is stupid question, but are you sure than in scene list the correct scene is selected when you build?

[random talon]

there is only 1 scene

[astral wave]

I had once after upgrading that it was not open scene inside, but had same name.

[random talon]

and before Unity6 the webgl worked on everything, even android and iphones (which was a mess to deal with but at the end everything worked)

[toxic jewel]

Anyone run into black screens + RenderPass: The dimensions or sample count of attachment 0 do not match RenderPass specifications in built games for WebGPU in Unity 6? I suspect it's related to render texture usage, though I've had similar projects work fine in 2023.3beta

[uncut solar]

I have been trying Unity 6, and using our custom WebGL Templates from previous versions, however keep getting a strange error that doesnt make much sense to me.
Preprocessor error "ReferenceError: USE_WEBGL_1_0 is not defined" occured in file "C:/Repositories/ProjectName/Assets/WebGLTemplates/CustomTemplate/index.html" when evaluating expression " USE_WEBGL_1_0 "

The documentation shows that it still exists, as it did in previous versions, anyone else running into this issue? or perhaps know what has changed so that its no longer recognizing it?
https://docs.unity3d.com/6000.0/Documentation/Manual/web-templates-variables.html

[sweet oriole]

https://discussions.unity.com/t/removing-support-for-gles2-and-webgl1-in-2023-1a/899819
Could be a mismatch in template documentation and the state of Unity itself.

[somber valley]

**[Solved] **
Edit: there was an error inside the C# method being called but the thrown error wasn't being clear what the issue was.

~~I'm using this C# method to call the code in the jslib

public static extern void GetAnnotation(Action<string> result);
(...)
GetAnnotation(AnnotationsCallback); // call .jslib method

Then the method in the .jslib is called and I query a string from my database, which returns with success:

    var notes = await window.unityInstance.user.getAnnotation();
    var bufferSize = lengthBytesUTF8(notes) + 1;
    var buffer = _malloc(bufferSize);
    {{{ makeDynCall('vi', 'callback') }}} (stringToUTF8(notes, buffer, bufferSize));
  }

And this is the method it should call with makeDynCall:

[MonoPInvokeCallback(typeof(Action<string>))]
public static void AnnotationsCallback(string returnedStr)
{
    Instance.noteInput.text = returnedStr;
}

But the method is never called, instead I get an undefined exception on the browser console with just some random number.
These methods were basically copied from the documentation:
https://docs.unity3d.com/2022.3/Documentation/Manual/web-interacting-browser-example.html~~

[arctic rose]

Show the full error message

[astral wave]

and just in case write file location directory 🙂

[somber valley]

The error messages aren't helpful, it's always some random number sequence so I can't figure out what is wrong.

[arctic rose]

Have you confirmed that it's not the user.getAnnotation call that's throwing the error? If you replace it with var notes = "test"; does it still throw?

[somber valley]

I did, the debugger returns the string just fine.

[arctic rose]

Which line throws the error then?

[somber valley]

It was the makeDynCall but now I figured out that there was an error inside the C# method being called.

maybe the random number was because it's unmanaged code being called

Also it seems like the correct way to make the string conversion is by using stringToNewUTF8

[thin stone]

just installed unity 6 to test out the improvements with web builds
https://discussions.unity.com/t/unity-6-updates-for-platforms/1529798

"Now, you can run your Unity games anywhere on the web without limiting your browser games to desktop platforms."
How exactly? The same way as before by installing Web as a build platform and building to Web?

"Additionally, you can embed your games in a WebView in a native app or use our progressive web app template"
That sounds cool but how?

Is there some kind of switch I need to flip or do I just make a Web build like I always do?

[sweet oriole]

Mobile browsers are just officially supported now. Part of Unity committing to mobile browser support and part those browsers and platforms becoming more capable. There is a PWA template, but I'm not too familiar with the mechanics of it.

Webview support is probably a similar situation.

[queen dagger]

Correct me if this is the wrong place to ask but is anyone working on or know of an existing game on the web that is a virtual world where you customize your character, chat with other people, play mini games, decorate a living space, things like that.

I already know about frog Paradise and hedgehog Creek! Thank you! Ping me your responses!

[toxic jewel]

https://theportal.to/
I think one of better examples. Well it is full of crypto, but some people like it. There are others metaverses as well. Most of them have some or all of these features. If needed i can give more, but they are quite behind in comparison with theportal.to. Also it is created on unity so you will get good image what can be done. Sadly it does not work on mobiles, at least yet from what I remember.

[queen dagger]

Thank you!! I'll look into it.

[queen dagger]

Do you know of any 2d ones?

[astral wave]

2D is rare ones, I have saw only one I think, it was japanese application for remote work. It had all features you mentioned, but I cant remember th name now at all.

[astral wave]

so most of them I saw was remote office, like "Gather" and etc

[queen dagger]

Thanks for taking the time to answer my question!! As someone who played games like animal jam classic and club penguin, I miss 2d virtual worlds that are MMO.

[surreal marlin]

Has anyone ever gotten an error like this in a WebGL build?

Ive been searching everywhere but cant find a fix

My project is pretty barebones
Works in the Editor on Web Platform and with multiplayer mode

Unity 6 LTS

[arctic rose]

If you've made your own JS plugins you'll have to use makeDynCall instead of dynCall. If not, you'll have to disable the WebAssembly.Table option to make the old dynCalls work

[surreal marlin]

I havnt made any js plugins. Just unity 6 and the multiplayer sdk really. Where would I find and change this?

Is there a way to host the .wasm file in a different location than the rest of the game? I tried editing all the references to build.wasm to just https://example.com/build.wasm but that doesn't work

[twilit sluice]

https://discussions.unity.com/t/disabling-splash-screen-causes-black-screen-on-some-devices-unity-6000-0-0f1/947210/6
Also I am having this issue. Does anyone know a fix?

[arctic rose]

You'll need to set the correct headers for the wasm file server, at least CORS headers and content-encoding if it uses Brotli compression. But it depends what the error is.

For the splash screen, you'll probably have to wait for an editor update

[orchid bridge]

heeeelp it keeps happening

I already installed IL2CPP from Unity Hub

[orchid bridge]

wait.. it seems to just be VPP messing up. The Professional edition has it fixed but they didn't update the Community version

[faint ice]

I am trying to build DOTS Project for webgl but it keeps crashing. Is DOTS still not support for webgl?

[twilit sluice]

I fixed it by moving all files to a different place instead of only the wasm file

[sweet oriole]

Depends on which parts of DOTS you are using. I wouldn't expect ECS, Jobs and Burst to crash, but Entities Graphics might.

Jobs and Burst generally range from not being very effective to being unsupported, but I imagine they have fallback mechanisms that get a lot more testing.

[brave thicket]

How can I send browser push notifications from a WebGL game or my backend, can't quite find info on it in Unity, I assume the game would need to ask for permission first?

[arctic rose]

You'll have to research how to do it in Javascript and make a JS plugin

[random talon]

Do somebody have knowledge on using the NativeWebSocket library?
I'm using it to enstablish and manage a websocket connection that works also on WebGL build.
It worked like a charm until I added a header, in this game the connection only works on editor

Hello, can someone help me with getting the Unity player on a custom site? I tried pasting the html to the right part and the stylesheet to the <head> part, and it does work, but it doesn't show the full screen button

So I copied the part between <body> and </body> to the right part of the html and I copied the <link rel="stylesheet" href="TemplateData/style.css"> to the <head> part

[chilly narwhal]

Actually, for cross support, would checking for (dynCall === undefined) inside .jslib tell us that we need to use makeDynCall instead of dynCall?

There is also a forum thread for .jspre not working when 'Decompression Fallback' is on. Does anyone have the same issue with it? Saw that forum thread randomly today, asking just in case if .jspre is known for being not reliable

Hey guys, we are trying to deploy to webgl a game online and i seem to be having issues with Iphones, i know they require ASTC compression but for some reason they still are not able to run it the pages say a proble repeatedly occured, works fine on dekstop, works fine on android

[woven ibex]

hi gang

I made this using chatgpt and

it's working nicely, except for loading the file

made a thread to avoid flooding

the error I'm getting says that Unity is not initialized

this is where my console on the browser is referring me to

[woven ibex]

also, do WebGl lose quality when built? 🤔

[astral wave]

https://docs.unity3d.com/6000.0/Documentation/Manual/webgl-server-configuration-code-samples.html
Maybe you did not setuped your server to support wasm. Just a guess.

[astral wave]

this one answer is: it depends 😄

1. when you build there a specific build options that will compress your textures to specified quality and format. Which could lead to some noise and quality drop after the build.
2. When you build and run webgl, you will notice that the window resolution is quite different from what editor runs at. And the comes the real enemy -< SCALING. And scaling can cause really a lot off quality problems. Like image instead o 512x512 becomes 269x269, where you lose data and some pixels can look different making it look bad. It can be solved with adjusting html code and build options.
3. by default project have quality settings: high, medium, low. And they are set to be default different depending on the platform. So in short on webgl it might change to lowest quality settings option 🙂

[astral wave]

it is always better to check console for more precise error. (f12 on chrome for example). Make sure to check there, then make sure the loading order of you script is correct, like unityInstance is not defined after actually using it. And check the template code, as unityInstance name changed depending on unity version.

[woven ibex]

well all I get is this

[astral wave]

https://docs.unity3d.com/es/2018.4/Manual/webgl-interactingwithbrowserscripting.html

https://docs.unity3d.com/6000.0/Documentation/Manual/web-interacting-browser-unity-to-js.html

make sure you template have something like this:

  var unityInstance= null;
  script.onload = () => {
    createUnityInstance(canvas, config, (progress) => { /*...*/ }).then((unityInstance) => {
      unityInstance= unityInstance;

Aka make unity instance into global variable that you can easily access.

[woven ibex]

that's my... html thing?

the
index.html

[woven ibex]

I don't get this much... it's my first time using webgl

[astral wave]

id depends which template you are using. Normally the place you have your js code to load unity. It can be in index.html or other location. depends on project and template.

[woven ibex]

I assume it is the index html

the zip is to upload on itch

[woven ibex]

okay so put that on my html

where would I put that exactly tho?

[astral wave]

createUnityInstance(canvas, config, (progress) => { <..> }).then((unityInstance) => {
      unityInstance = unityInstance;}

and write other code you need. Or something like that.

If you would using unity 6 template you could see something like this:

script.onload = () => {
        createUnityInstance(canvas, config, (progress) => {
          document.querySelector("#unity-progress-bar-full").style.width = 100 * progress + "%";
              }).then((unityInstance) => {
                document.querySelector("#unity-loading-bar").style.display = "none";
                document.querySelector("#unity-fullscreen-button").onclick = () => {
                  unityInstance.SetFullscreen(1);
                };
<..>```

which gives you place where to look.,

[woven ibex]

var unityInstance;
      createUnityInstance(document.querySelector("#unity-canvas"), {
        arguments: [],
        dataUrl: "Build/Jaro TCG - Web DeckEditor.data.br",
        frameworkUrl: "Build/Jaro TCG - Web DeckEditor.framework.js.br",
        codeUrl: "Build/Jaro TCG - Web DeckEditor.wasm.br",
        streamingAssetsUrl: "StreamingAssets",
        companyName: "Devour Labs",
        productName: "Jaro TCG - Editor de Mazos Web",
        productVersion: "0.1.0",
      }).then(function(instance) {
        unityInstance = instance; // Assign to global variable
        document.getElementById("loadingMessage").style.display = "none"; // Hide loading message
        console.log("Unity instance created successfully.");
      }).catch(function(error) {
        console.error("Failed to create Unity instance:", error);
        document.getElementById("loadingMessage").innerText = "Failed to load Unity app.";```

[woven ibex]

oh, didn't know about these templates

I used chatgpt for what you told me, I haven't tried yet but will soon

I bet something else will now have an error but at least is one step in the right direction xD

[astral wave]

yea chat gpt likes dream a bit on unity webgl 😄

[woven ibex]

tomorrow I'll check back on this and take a look at what you sent

thanks for caring even if it doesn't work, I appreciate the effort xD

also would like to know where exactly I should look into to make my cards look clearer

[woven ibex]

I tried changing the texture compression format and such... that took one hour and made no difference xD

[astral wave]

first check quality settings and platform connection in player options /quality ->

There green color indefies which quality setting is default. And icon with small 5 (last icon) means WebGL platform.

[woven ibex]

fire! thx dawg, I'll check those out

time for bed, sweet dreams everyone

Researching if Unity's new input system doesn't allow key rebinding in WebGL, or if there is any documentation on keyrebind WebGL specifically.

Having issues with it? Not aware of such limitations, but you could try building one of the input rebinding samples to make sure.

[solar hound]

Hello friends, I have a cache issue in my WebGL build. I update my app on the server a few times a week and can not see the updated version without a clear cache in the browser. Here are my WebGL player settings. I want my app updated when I upload the latest build to the server without manually refreshing the cache. Please help me!

[torn pagoda]

That sounds like a server / browser issue, not the webGL part. As long as your website is not forcing the cache to be cleaned, it will remain, as the webgl wont have access to delete files on the users machine

[solar hound]

@torn pagoda that's correct we can not handle browser caching from the Unity side, but I update my app daily so it is necessary for users to clear previous caches to get the latest version.

[torn pagoda]

Again, thats a server issue on the config, how long it will store the latest build or on the users browser. I think, you need to serach for some website specific cache configs or server side configs to change instead of the unity build settings

[sweet oriole]

Tick Name Files As Hashes to make sure changed Unity files have a different name to reliably prevent caching anywhere in the chain. I would keep data caching on.

Cache busting of files other than the ones Unity builds needs to be handled separately, but the strategy would be the same.

[knotty yoke]

Hi, so, maybe my question is best asked here.
I'm trying to hook google analytics into Unity for a desktop game so I can publish it on itch. All information I can get about how to do it is aimed towards Android and iOS. Does anyone know how to do it or share a link to a website/video that explains how to set it up?

thanks!

[arctic rose]

This channel is for WebGL so it's not the right place. But the instructions are the same for all platforms: https://firebase.google.com/docs/analytics/unity/start

[knotty yoke]

Thanks for the answer. I forgot to clarify, the itch version is supposed to be in WebGL, not sure if the process is the same for desktop.

I checked the firebase documentation and it only explains for mobile, and in the app setup it tells me to pick if it's for iOS or Android (or both), so I'm not sure how to do it if I'm just having it from web.

[arctic rose]

What app setup?

[knotty yoke]

this thing here.
Some context, I've always used in-house analytics so I'm not sure how to set up and work with firebase and google analytics.

[arctic rose]

Use the web app template (</> button)

[knotty yoke]

oh ok, so just normal web and doesn't matter if it's unity or not, got it. Thanks! 🙂
Do you know by any chance if doing this would work for desktop apps?

[low oasis]

Ok I built web build, and testing

Same issue on blank project

[arctic rose]

Yes, all of them do the same thing. The only difference is what instructions it shows after adding the app

[low oasis]

@halcyon hedge how about ur?

[knotty yoke]

ohh! that's awesome!
Thanks!! ❤️

[low oasis]

I u said it was web build?

[halcyon hedge]

yes but its still building, i think it got stuck cause my battery died

[low oasis]

It build long for me too

I'm using SSD but was too long

Are you using HDD?

HDD was too slower than SSD

I found some asset package is postprocessing audio, so removed all and try re-build

[halcyon hedge]

no Im just doing it normally but my laptopfroze and I think it interrupted the process. Im just going to try my desktop, be back in 10

[low oasis]

Aha I see. Thank you to testing

This build is same on chrome and firefox (+edge)

[halcyon hedge]

ok confirmed, okay something is definitely different on webgl

[low oasis]

same with my video?

[halcyon hedge]

the pitch is also lower

[low oasis]

in editor it is seamless

but only web has that pop sound

[low oasis]

Oh didn't know that

web build force to usc AAC compression

[halcyon hedge]

yes there is a higher pitch in the editor but its a lower pitch webgl

[low oasis]

hm then it is issue of AAC ompression in the unity it self.

also did u hear pop sound?

[halcyon hedge]

not so much of a pop but yes its like a silent space

[low oasis]

oh so this was unity bug

Thank you so much to testing

[halcyon hedge]

idk if its a bug or just wrong exporting settings, I would need to try different things around settings and see further whats going.

[low oasis]

Aha ok, I think setting will force to set like this

There are few option to change setting here

[halcyon hedge]

there are other settings too iirc

[low oasis]

I assume unity compress audio format to AAC, but it make small void area

I can only see this setting

[halcyon hedge]

apparently Unity uses heavy modded verison of FMOD but in webgl they dont

[low oasis]

Oh

That would be reason

Then If it is caused by leak of FMOD in webgl. I think there is no solution now?

I found all supported audio format

and I remember mp3 had more delay for each loop

forum suggest to use wav to seamless loop. and i also test .ogg, it is also not working

[halcyon hedge]

I just told you FMOD is NOT what they use for web, they have to rely on the built in web apis

thats whats causing issues

here found this this explains further of looping issue https://discussions.unity.com/t/seamless-audio-looping-in-webgl/1497212/4

[low oasis]

Oh I see and thank you to share, I saw this before but now staff added new comment !
I should try it

[halcyon hedge]

yes it sucks that web is this way, but it is what it is

[low oasis]

if mac build works well, i think it was also working well on your laptop

by the way, i found FMOD with unity web

https://www.fmod.com/docs/2.02/unity/platform-specifics.html#html5webgl

I didnt understand this 'Support for WebGL is included with the base integration'

FMOD support WebGL basically?

https://fmod.com/assets/html5/js_unity/demo.html

Also found official sample

[halcyon hedge]

You can try it and see

cause the docs says this

Because Unity uses FMOD
to manage audio for platforms, the Web platform supports limited audio functionality, which only includes the basic features. FMOD relies on threads, which the WebGL
API doesn’t support. For this reason, Unity uses an implementation based on the internal Web Audio API, which enables the browser to handle audio playback and mixing.

https://docs.unity3d.com/Manual/webgl-audio.html

[low oasis]

Oh Thank you

[low oasis]

hm. I also tried to this method. can't find smpl chunk with hex editor

[low oasis]

So I just should fade in / out audio start and end

[sterile burrow]

Im facing a weird issue with WebGL builds on Safari. It seems to be a Safari bug of kinds.

What happens is on first load, it will load the game in to memory, but after every consequent reload, it just adds more and more to the memory unless i complete shut off safari and re-open it..

It get's more weird though, i've tried refreshing the game a couple of times (going from 600mb, to 1gb, to 2gb, to 3gb, etc..) and then switching to another domain (nu.nl), in which case suddenly, the nu.nl safari page keeps using a whopping 6gb of RAM and keeps automatically growing without me even doing anything.

I've attached screenshots of my mac Activity Monitor, to show it growing as I reload, and the switching to nu.nl and it continueing to use so much RAM..

(3 reloads on game, then switching to nu.nl, then a couple of seconds after nu.nl load)

[radiant anchor]

Hi Im wondering is there's any function i can use to clear cache of my webgl game?
So the problem is if user already open the web(im using AWS s3 bucket) then i update the web, the user wont get updated build and user need to clear cache of that web first to get that updated build, so i want to solve that issue, is there's anyway i can do to achieve this?

[radiant anchor]

i research a bit in unity discussion and some of them said delete IndexedDB.deleteDatabase, but when i tried it said Database Detection Blocked: /idbfs
Database Detection Blocked: UnityCache
And yes that 2 is the one i need to delete based on unity discussion i read, any idea on this?

[thin stone]

not sure whether to post this here or in #📱┃mobile but i published a unity 6 web game on itch.io intended to be played on mobile and it works on brave browser and chrome but in firefox it doesn't go into landscape mode properly, is there a way to fix this?

i tried Screen.orientation = ScreenOrientation.LandscapeLeft; but it didnt do anything

[burnt linden]

Hi, what I need to do to make the Gyroscope/Accelerometer work on the publishing platforms like itch.io or CrazyGames?

I created a Unity Asset that works via local Wi-Fi testing with HTTPS self-signed cert. But one of my clients says that it doesn't work when uploading a Unity WebGL build on the itch.io.

My Detailed Post on Unity Discussions: https://discussions.unity.com/t/gyroscope-and-accelerometer-sensors-on-webgl-using-itch-io-or-crazygames/1555386

[hardy hamlet]

how would i make a webgl file of a unity game

it was pc mac platform

now i put it to webGL and it bombarded me with errors

when i tried to build it

[lunar ibex]

Deal with them? It's a bad practice to tell that you are getting errors without specifying them. As far as I know not every aspect of unity can be utilized on WebGL, so you might be having to redo something. Also, I might be wrong, but you are never getting a webgl file. You re getting a Build in a folder with... subfolders and stuff in it.

[gleaming cape]

Hi guys, i have a question. In our current company we are planning on publishing our games on our own site and so we need to show game ads, since sites like Poki etc provide their own sdks for ad integration, is there any sdk available that is not attached to a publishing platform for webGL? something we can use independently?

[sweet oriole]

Any browser advertising solution can interacted with through https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html. Adinplay is one that specializes in this space and helps to shield you from mistakes that could get you banned from big ad networks.

Okay, this is a bit of a stretch, but I'm out of options and I can find nothing online that works. Has anyone here ever managed to get a Unity WebGL build running in a Blazor Web Application? I'm pretty sure I've got all the files in the right place, but it's giving me a 404 when trying to load the JS. I've put the build directory in wwwroot and added the contents of the index.html to the page I want, but it just isn't loading anything.

The closest I've found is this discussion but I have zero idea what the solution means, I know Unity not Blazor.
https://discussions.unity.com/t/unity-built-for-webgl-embedded-into-a-blazor-application-wont-instantiate-properly/730703

[junior basalt]

Is there an ETA on when WebGPU will come out from experimental? And is there a roadmap that provides info on what would be a prerequisite for it to graduate from experimental?

[sweet oriole]

Did you check what path it's trying to load these files from and whether it seems correct?
Seems relevant: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/static-files?view=aspnetcore-9.0

[hoary rose]

I'll have to check it tomorrow, once I'm back at my work computer. I put the files in wwwroot and the paths all seem correct, but going to that path is giving me a 404

I don't have access to it at the moment to confirm that, so I'll double check tomorrow to confirm, I might have just made a mistake somewhere with the pathing

[sweet oriole]

I would seek some sort of output of what files are ending up on the server and where they are.

[amber ginkgo]

https://discussions.unity.com/t/webgl-builds-on-ios-keep-refreshing-or-crashing-when-focus-is-lost/1556670

hey, that's a question I just created. didn't re-write it to void spam. would appreciate help on this 🙏

[sweet oriole]

I recall multiple people talking about this 500MB barrier on iOS Safari.
On here: <#🌐┃web message>
Screenshot from Web Game Dev discord.

[amber ginkgo]

i just made a test project at https://gameserver.crownchaser.com/testtool/ where it even crashes at 280MB if I open another app and come back to this.

oh let me add this to the Discussion topic too

[sweet oriole]

I can imagine Safari becoming even more aggressive if it ever goes to background

[amber ginkgo]

after the first crash all hell breaks loose

[amber ginkgo]

summary: it falls in a reloading loop. game loads, reloads, loads, reloads

[amber ginkgo]

that makes sense, but on Android and Windows, all browser swap the memory instead of just causing a crash or a reload in the app.

i haven't seen similar issue on any other device than iOS

i partly think it might be a config issue

suspect this as well

will test with it as 1GB

[sweet oriole]

Maybe other people have some tips. The aggressiveness does seem unique to iOS.

[amber ginkgo]

the hell loop is unique to Safari alone. it doesn't reproduce on iOS/Chrome

[amber ginkgo]

changed the player settings' memory alloc settings to start from 1000MB and incrase with up to 1000MB at a time with a 1:1 ratio. that seems to have increased the crash/reload threshold to ~880MB :|

[amber ginkgo]

ok now with the new player settings, the actual game runs fine too... so all this time it wasn't the 500MB mem limit, it's the allocation strategy that hit a limit that it had internally set for itself

here's the settings. in case any future webgl dev needed it

[hoary rose]

Okay, this gave me the reason why it isn't loading, but I'm still not sure the solution. It looks like the Blazor app doesn't load any unknown filetypes unless you specify what they are supposed to be. The js is loading fine, but all of the br files are not. What is the mimeType for data.br and wasm.br? framework.js.br is presumably, text/javascript but what about the other two?

This is so unbelievably close to solving it but I have no idea what they're calling MapWhen on. They didn't include full code so I don't know what object actually has that. Searching for Blazor MapWhen isn't giving me anything specific either
https://discussions.unity.com/t/blazor-server-app-cant-get-brotli-compressed-webgl-build-running/909081

Oh, hang on, I think I found it, making progress...

Woohoo indeed!

[restive mica]

hey, how can I run my unity project on my own website without loading Unity Play?

[arctic rose]

Compile the project to WebGL, upload to website

[restive mica]

I have published and build the project using WebGL, but I don't know how to proceed further

I've tried adding the embedded code i.e. the iframe through the webpage but it loads the Unity Play page, tried to host the index file on python but it shows the https restrictions

[sweet oriole]

Are you using the WebGL Publisher package? Do not use the package if you want a normal WebGL build.
Documentation for the normal build process https://docs.unity3d.com/6000.1/Documentation/Manual/webgl-gettingstarted.html

[silver reef]

hi, sorry to my eng.
I have question for optimizing Simulation in WebGL.
As I Know, WebGL using Unity does not support DOTS (except ECS).
and Multi Threading also.
recently I found some clue for multi threading using Native PlugIn.

And I read Native PlugIn DOCS. docs shared some rendering example project using DirectX renderer.

these solution really faster, efficient than Unity Rendering?

And
Some Company suggest, Use Rust PlugIn at Unity, as MultiThead ECS machine. And Then, they make 10K Object Crowd Simulation In WebGl.

It is really possible..?

[sweet oriole]

You can't just start executing native code simply by someone visiting your website for security reasons. You might be able to hack the browser to do this if you control the machine used to run the browser, but at this point you might as well build and run a native build.

What are you trying to build? What is your bottleneck?

Fastest running solution is always the one that is specifically made for your problem, but that can require a lot of investment.

[silver reef]

thank you replying.
if security problem exist, maybe these approach will be wrong...
currently, we make our digital twin platform for goverment.
we make predicting population risk and control using realt-time/ time series data.
Simulating Crowd / Traffic / Shipping will be good point for customers.
so, I trying to rendering many population object as possible as.

my bottleneck simply in my desire for displaying so many objects.
currently, my limitation performance is 40~50 FPS, Draw Call was only about 4000. (each object has 3,000 vertics object.)

[thorny ember]

I have been running the unity profiler for a webgl build. All the assets highlighted in red are 3rd party assets in my file tree but are not used in any scene. When I inspect with find in scene it returns nothing. How is it possible for objects end up in RAM despite not behind used in any scene?

[sweet oriole]

Tools to debug build size might give a clearer path to how these assets are ending up in a build.

[sweet oriole]

That's a pretty high draw call count. Are these animated objects? You might want to look into alternative ways to animate meshes.

Engine multithreading should work as long as you don't need to embed the build on other sites (CORS reasons).

[jade garnet]

Hello, I have keep having an interesting but simple issue with my build, I think....

Anyways when I build to web and upload the project I can see everything in the scene on my computers web browser, but for some reason when I pull it up on my mobile phone none of the models show up. I even changed the materials on them to mobile compatible shaders, this did not help, I also checked to see if they were actually in the scene with a dbug log printed to a UI text field. I am not getting any errors. I am using a blank scene with 3 default object in it.

If anyone knows what I could try, the help would be gratefully appreciated.

Web: Mobile:

[astral wave]

did you get the UI text on the screen successfully? Have you tried if you can see default objects with default materials? what phone are you using? hat rendering pipeline are you using? What browser are you using?

[jade garnet]

I can see UI just fine, but it's something with the textures, the objects are not being displayed.

Also using URP, and it's not a bowser issue, I tested it on several and it was only phones that were affected.

I was able to get them working by using other textures than the default ones. But I was hoping I could fix it without using other custom textures, because it just adds more to the process oh well.

[astral wave]

" was able to get them working by using other textures than the default ones. " what do you mean by that? are you using some kind of custom made shaders?

[jade garnet]

I was not before but now I am the standard shaders we not working, but I could not find just mobile shades to use. The ones I am using now are a bit better though. I can do more with them.

[astral wave]

In order to debug this problem I would start with step by step approach. It will take time but you will know where exactly problem come from. Start ne project, add one object with default material. See if that works on your phone. Then keep adding your objects one by one, try doing as small steps as possible to find which step exactly causes the problem. You can also try adding your textures or materials that works by default. This way you can confirm if that is texture problem shader problem, project settings problems.

[jade garnet]

For sure that is defantly the best solution I have for this. This will help a bunch. Thank you for the help.

[dapper jewel]

I'm confused, according to this post https://discussions.unity.com/t/web-build-with-ecs/1548460/5, Unity jobs system doesn't work on the web platform.

But at least with WebGPU + with "Enable Native C/C++ multithreading" enabled, my web build seems to spread across some worker threads?

Although on it's only spread out to 4 worker threads compared to when I'm running it natively. I have a 12600KF (10 cores, 16 threads)

So...jobs sort of technically works? Here's a build with multithreading turned off

[sweet oriole]

Challenge with WASM threading is publishing, as the common security configuration on websites ends up disabling it.
Godot actually had a nice post about it https://godotengine.org/article/progress-report-web-export-in-4-3/

[dapper jewel]

Oh interesting, I'll definitely check if there are issues with different OSs, browsers, and hosting websites, bur honestly, the fact that it's not burst compiled makes it feel a lot less worth it lol

[stoic tinsel]

Wait really, does that actually work and you're profiling the browser, not the editor with WebGL build profile active, there?! If so that's very interesting, because I was about to write a load of C++ for some WebGL multithreaded stuff, and want to know if I can actually do C# (interestingly not because I dislike coding in C++, but because I hate CMake...)

Are your jobs burst-ed? Theoretically, the problem with WebGL Multithreading is (as I understand it) the garbage collector. Now, since burst can't create garbage, is it possible that bursted webGL jobs can actually be run on worker threads? If so, that would be amazing... but I can't understand why Unity would have enabled that without announcing something so awesome.

[dapper jewel]

Yup I profiled the app running in Chrome - it didn't burst compile though. You can compare 1st and 2nd screencap for see the difference between running on Chrome vs in editor

[stoic tinsel]

Interesting and... surprising... I was sure I did some tests early in Unity 6, and Unity.Jobs.LowLevel.Unsafe.JobsUtility.JobWorkerCount was always 1 in WebGL builds no matter what you did. Running a test now, but on the other hand, I'm not sure how this fits in with the GC in WebGL (which has its own ickyness that it can't run mid-frame, some of our larger loading/init tasks that generate lots of garbage even have await Awaitable.NextFrameAsync() scattered through them to let the GC run, because otherwise on Web it won't and our high water mark is too high...)

[stoic tinsel]

Yeah, you're right - Unity now (6000.0.26) reports 5 for Unity.Jobs.LowLevel.Unsafe.JobsUtility.JobWorkerCount in chrome! Which seems amazing, but I can't repro what you're seeing with jobs in parallel because even the simplest IJobParallelFor Dispatch I can do seems to crash with "call stack size exceded" in WebGL. Are you using IJobParallelFor there? Or IJobFor? Any other details to repro a minimal verion of you have?

[dapper jewel]

Sanity check - is your "Enable Native C/C++ multithreading" setting turned on in player settings? Having it turned off will make the job run single thread (see 3rd screencap)

[dapper jewel]

Tested on an empty project with only this behavior. Unity 6000.0.28

[stoic tinsel]

Thanks. I'm not currently able to run your test either, going to try a new project, in .28 instead of 6000.0.26.

I've definitely got C++ multithreading on - lots of my embedded C++ plugins fell over when I enabled it because you need to recompile any wasm libs you've built with different flags (which will mean a load of vcpkg / cmake misery...)

[stoic tinsel]

WebWorkers

[solar hound]

how do I force open my webgl build always in landscape mode

[charred briar]

You can't.

Orientation is dependant on the browser

You can request it though on the javascript side https://developer.mozilla.org/en-US/docs/Web/API/ScreenOrientation/lock` - keeping in mind some browsers (Safari for example) will ignore it.

What I usually do is show an overlay on portrait that tells the user they need to rotate their phone

[amber ginkgo]

Hey!
On iOS our web game gets reloaded mid-game. Not even opening other tabs or apps. I've made sure the game pre-allocates all the RAM it'll need so there's no sketchy big alloc happening that would make the browser optimize the tab away. Also, game's not that demanding, and I don't get any errors for the reload so it's not a software crash either...

Anyone has any suggestions on where to look?
The issue started happening after we added a ton of new vfx, so VRAM is probably twice more occupied than before, but CPU and RAM wise nothing has changed between the working and the not working versions. Also, the vfx are just using a simple additive texture shader and they're instanced heavily using Unity's particle system.

reference: demo.crownchaser.com (game's entry code is cc-entry-secret)

Some more info that might be helpful

• pre-allocated ram is 1GB , the crash happens on iPhone 14 pro which I believe has 8GB , and the error happens with no other app opened, so at least 4GB free.
• I can't seem to replicate the issue on clean iOS installs on live iOS testing websites (they don't let me install a lot of apps to replicate a busy OS and then close them all to replicate the scenario)
• The crash happens during the demanding scene where all the new vfx are loaded. I've benchmarked the internal allocator (which simulates allocation, but really it's just using the pre-allocated memory internally. It's a Unity feature so it's solid) and the demanding scene tops at around 400MB of ram, nothing too big.
• I have no idea how to benchmark VRAM on web, so I have zero info on that, but if needs be I'll provide some, given it's possible that is, because it may really be a blackbox.

[astral wave]

First to be sure, you don't try to use VFX graphs right? As webgl don't actually support that..

Your problem sounds very much one we had. Things that I learned about it:

• pre-allocated ram memory that browser reports don't really matter in this case
• you need to use Unity memory profiling on your game to see how much memory it actually uses
• when you reach about 300-400 mb RAM usage, unity webgl becomes unstable and starts crashing/reloading. This limits is for iPhones 15 and older (android don't have this problem), newer devices don't seem to have it, or the limit is higher.
• other webgl platforms like PlayCanvas do not have this problem. It seems it is something with wasm. if you search you will find a lot o people complaining about it.

So that is my guess what happening to your app. I really suggest to connect Unity profiler and check what exactly happening

[solar hound]

@charred briar Yup! I just put a dialog to inform the user to rotate the device. Thanks!

[amber ginkgo]

hi. no vfx graph, it's all either shadergraph or raw shaderlab script.
Thanks for the thorough reply! 🙏
in our testing, the game uses just above 500MB of memory at max, but also in a benchmark I wrote, the tab could allocate up to around 800MB of ram before the browser killing it. And even then, it would kill it with an error message, not a tab reload. Right now the game tab just straight up reloads, no error, no special logs, nothing. it just reloads 🥲

+++ We did have a memory issue and it was pretty much like you desribed. But we solved that before and the game was running fine at <500MB ; the new "reload" problem only started happening after we added a lot of new vfx (which still don't cause the memory to go beyond 500MB, and even if it did, definitely not beyond 800MB. What's more, we preallocate 1000MB anyway so no alloc/dealloc...)

I suspect that as much as this issue is similar to the infamous RAM issue, it might be related to something else, say, VRAM?

[strange grove]

I have a webgl 3D game. Im currently on a prev version of unity rather than unity 6.
The problem i have is that if i upgrade it to unity 6 my game crashes on IOS after 11 - 12 rounds. But it doesnt crash on the current version even after 30-40 rounds.

what can be the issue here? if anyone has any idea

[astral wave]

Out of interested, how did you solved that issue? It indeed sounds really really like RAM reload and relocate issue we talked, no errors, just reload on iOS. As preallocating more memory did not solve that issue for me, as I told, browser and iOS memory usage are bit different issue.

Coming back to your issue tho, Are you using addressables or something like that? You could test VRAM usage with profiler, set everything to lowest quality and see after reducing usage of VRAM does crashes still happen.

[astral wave]

Well, the answer would be profiling. As you have pretty specific crash time zone, so you can test it. At crashing point check what resources are being used, maybe you have memory leak somewhere, and each round keeps loading extra assets or textures over and over again. I haven't personally noticed any crashes with Unity 6 yet, but in your place I would:
a) check quality settings and build settings. As unity 6 added new stuff, they might be automatically enabled and using more resources than usual in older version. And then you hit iOS limits.
b) After upgrading I would delete library folder and start Unity again to rebuild it from scratch. Sometimes it causes weird bugs as old compiled code don't flow with new code.
c) triple check build settings

Is there any errors on crash? you can check logs with chrome://inspect in different tab to see logs you get.

[strange grove]

Sure will check that

[amber ginkgo]

Same problem haha apparently it's RAM related. Keep it under 500MB. Profile and detect any memory leaks. Use brotli and adjust the server headers to send br for those .unityweb files

[strange grove]

I did use brotli

Im using urp as well which causes fps drop on android too

Will look into it

[amber ginkgo]

Nothing unity-related, just optimized textures and models.

I checked vram yesterday, it was around 400MB . Also I found a memory leak, fixed it and the issue still persists. (It wasn't a huge leak, just around 100MB over time)

++ on the question of what I use for memory management, I use Resources. I profiled it and it does handle memory properly

after the addition of editor-only serializable fields in Unity 2023, I've found writing my own Resources wrapper is a lot better than using Addressables. You also get all the Editor goodies with exposing editor-only object reference that doesn't get into builds

[astral wave]

Do anyone knows if:

1. Does new input system support multi touch actions like pinch on WebGL?
2. Is there a way to simulate pinch action on editor to test if code works?

[amber ginkgo]

2. yes, i don't know about touch PCs, but Unity has a feature which lets you test your game on your device right there in the Editor. If you have an Android, checkout "Unity Remote" in playstore

[astral wave]

Thanks will try that for temporarry solution. aster than deploying webgl on server checking there.

[sleek thistle]

Ever figure this out?

[charred briar]

Fwiw it looks like it's trying to remove shaders and some badly tested unity build code couldn't find it, and errored

[tranquil willow]

Hii, I tried publishing a WebGL demo of my game on itch.io but it refuses to load. After getting multiple erros in the browser and trying different solutions I went with uploading to Unity Play and it works fine. Is there something I'm missing when it comes to itch.io WebGL hosting? Thanks

[arctic rose]

You'll have to show the errors

[amber ginkgo]

Last I used it it needed you to upload a zip to them, no compression done (so no brotli)
If you're sure you've checked all the basics fixes, it's time for checking logs on the website. In most browsers you can open the debug panel by pressing F12

[tranquil willow]

It's crazy cause after writing that message I went back and tried playing it and it worked. Then I exported the game again after fixing some bugs with the same settings and it doesn't work again. I decided to just upload to Unity Play and link it on the itch page. I'll check the debug panel sometime later though, thanks

what can I do about webGL having pink shaders?

its a certain asset pakc that isnt rendering shaders

how do I force it to do so

it also doesnt seem to have rendered any lighting or fog

[astral wave]

well it depends on shaders and where you got them. you have choices:

1. you convert the shaders to default shaders if possible. you lose something but at least it works:
2. you open shader code and try find what is bad and fix it your self.
3. you text a nice message to shaders creator and ask him to update to work on webgl.

who knows what features e is using for those shaders. If he using anything with compute shaders, you are out of luck. or any other thing from long list webgl doesnt have.

[orchid bridge]

pain and suffering

thank you for the response

see if it would render

I was gonna try to do this

[astral wave]

yes it is sadly. For advvantages wbgl have, it have its deal with disadvantages.

if you do not use addressables or other resource management tools, than all shaders should be included in build automatically.

[orchid bridge]

I dont

idk, ill try it cuz im desperate to not have to use default shaders

but if it comes down to it I will

thank you v much for your help

[outer wave]

I'd dig for errors like I've mentioned before. It'll probably tell you what operation the shader did and why it failed usually

like incorrectly sampling depth, ect

[orchid bridge]

could it be any of those?

idk how to read this stuff very well honestly

I didnt program anything about the game

Unity 2022.3.37f1 - Im getting a "memory access out of bounds" error on my webgl build when running on the browser. The first time I load the app, everything works fine, but when I hit refresh, and load the website again, it crashes with that error message. It crashes in the middle of loading unity. I've tried doing a clean build, and same thing happens again (first load works, subsequent crashes)

Uncaught RuntimeError: memory access out of bounds
    at il2cpp::vm::MetadataCache::Initialize(fishbait-web/) (http://localhost:3000/fishbait-web/Build/fishbait-web.wasm.gz)
    at dynCall_i (fishbait-web.wasm.gz:0x71f7654)
    at Module.dynCall_i (fishbait-web.framework.js.gz:4301:372313)

[astral wave]

I always mixing memory out of bounds errors, which is which.
As one is caused when you try to access array element that does not exists.
And another one is when you actually just run out of memory. Have you profiled your project how much memory it uses on WebGL and PC? Maybe you set too little starting memory on build settings (idk if those options are on 2022 or only starts from 2023).

You say it fails on reload. Does it fail on load even if full refresh with disabled cache ? Do you cache anything or read anyting from cache?

[woeful matrix]

The initial memory size is 32, and maximum memory size is 2048 according to the publishing settings. I use PlayerPrefs to store player settings like username, etc. So I think maybe thats the one being stored in cache

[astral wave]

Does full reload without cache also gives this error? It could be in theory: first load reads cache for playerprefs, it dosnt exists, loads the game. Then you save playerprefs in bad way, so when for second time it tries to load them as you already saved and thy exist already but with incorrect data, it gives you error. Tha is my theory one 😄

or you somehow store more than 1 mb of data. Like try storing images or something.

[woeful matrix]

So After, deleting the cache storage via the chrome devtools, the error went away. and it no longer crashes even after refreshing

[astral wave]

Maybe old cache was playing with your new build. I guess.. Yey?....

[woeful matrix]

yeah maybe..two of the entries got removed, when i reloaded. before there were 4 entries in the cache storage, now there are just 2. Glad that it worked. Thanks!

[amber ginkgo]

For cache issue, just return; on the first line of ServiceWorker.js , the cache works perfectly that way

I'm not very familiar with ServiceWorker but make no mistake Unity's caching is done internally not through serviceWorker or other standard solutions

Finished my first Unity project! Play the game on your desktop browser and leave any notes for me

One thing I find weird is that there is supposed to be text on the top left keeping track of your score. It's not on the web version, but on the computer version

[solar hound]

Hi, how do I open another Android app or iOS app from Unity WebGL??

[astral wave]

I would change this question to: how do I open another Android app or iOS app from JavaScript. Which will return you a lot of methods on google. And then from unity just call that JS script. As I am not aware of any methods to opening applications directly from Unity WebGL.

[cunning radish]

Congrats!!!
The text not appearing is probably an issue with your canvas scaling setup. You have to set the canvas scaler to scale with screen size and set the UI element anchors correctly.

[strange grove]

how do i get if app is in background or out of focus for webgl on native devices?

[astral wave]

once again, use JS and send message to unity;

document.addEventListener("visibilitychange", function () {
        if (document.hidden) {
            // App is in the background or tab is inactive
            SendMessage("GameManager", "OnAppBackground", "background");
        } else {
            // App is in the foreground or tab is active
            SendMessage("GameManager", "OnAppBackground", "foreground");
        }
    });

    window.addEventListener("blur", function () {
        SendMessage("GameManager", "OnAppFocus", "lost");
    });

    window.addEventListener("focus", function () {
        SendMessage("GameManager", "OnAppFocus", "gained");
    });

Examples

[strange grove]

I did try this it didnt work for me. My webgl game is hosted on discord as a discord activity

[astral wave]

Sorry I am not familiar with discord API and how its handles events like these.

[strange grove]

No problem thanks.

[brave cipher]

Hey guys, I've been struggling with this for a while, and I don't know where to ask. So i've made a chatgpt wrapper using unity and tried to export it to WebGl, but I keep getting a webassembly error. I'm pretty sure I can find another way to do the wrapper. I'm just wondering what went wrong and why it's broken, anyways it works fine and is able to be build in Windows.

[sweet oriole]

How are you connecting to the API? You need to use Unity's HTTP API or go through JS yourself to get networking.

[brave cipher]

Ahhh, yea I just use a .net libary for it ;-;

im guessing it's a CORS thing?

[sweet oriole]

I believe CORS errors would be more explicit than this

[brave cipher]

huh

[sweet oriole]

This could also be caused by some AOT limitation https://docs.unity3d.com/6000.0/Documentation/Manual/scripting-restrictions.html

[brave cipher]

ok, yea I'm pretty sure that's the issue as I'm looking into the lib

thank you

[restive mica]

hey guys, I'm working on a project as a complete beginner. I'm trying to build a webAR service for which I'm facing a lot of issues in XR plugins and to integrate AR part in the unity
can someone personally connect over and guide me with the same, it would be really helpful for me. thanks in advance!

[frigid root]

My project uses webGL 2.0 and photon PUN2
I have performance issues (~25fps or so) so i'm trying to enable multithreading however i'm getting these issues when i start trying to connect to the photon server.
Any ideas why this is happening, thanks in advance? Unless I'm just dumb in thining that turning on multithreading will magically fix performance issues. I also tried webGPU but that gave no significant increase in performance

[limber lily]

excuse me guys, does anyone ever had problems on UI buttons lagging or input lagging from webgl build?

my game runs smoothly but the UI inputs kinda lag escpecially when pressing TMP buttons

[astral wave]

Because WebGL does not support multithreading. It support only C++ code multithreading, which means no C# multithreading. No jobs and etc. To be clear, you can use some features, but mostly you can't. you migt want to connect you profiler and see is it GPU or CPU that is bottle necking your project and try to optimize there.

[astral wave]

never seen that kind of behavior sorry. What kind of webgl input are you using? https://github.com/kou-yeung/WebGLInput ?

[frigid root]

Ohhh ok thanks 🙏

[limber lily]

What i ment was the new input system manager

I have a mobile controller using the new input manager system, the reaction time whenever the user pushes a button or move swipe the screen is slow

There's a significant delay

How do i profile in mobile browser's?

[astral wave]

Depends on your unity version. But normally in build settings you choose developer build, then there will be extra option stating: autoconnect profiler.

then press build and run. Then you will see all logs on editor from your webgl, and can use all other debuging tools.

[astral wave]

As from what I worked with input system swipes and touches did not have any delay. It might be some setup problems? Do you have any Procesors on your inputs?
Maybe it is a code problem, like you do something in Update function to trigger events in a bad way. Could you give example of code how you are using it? Are you using c# events? unity events? Sending messages?

[limber lily]

Its quite complex, I use a game from asset store. Its never ment for mobile, but I tried to port it to mobile inputs. Mind if I dm you? I probably send the detail later

[lunar ibex]

Any hope to find clues why WebGL on a specific Android device just gives you black screen if you touch it?
More modern Andoids seems to be fine...
Doesn't have to be a button, just any place on a screen
Before that point, max 60 fps and everything is ok
I have heard that specific mobile game issues are basically discarded cause it's too annoying and specific to get to the root, sadly...
And it's getting even worse if we start talking about browsers and WebGL I guess

[astral wave]

it sounds indeed like something difficult to solve. Especially as new devices seems fine. Most commonly the issues with different devices comes to:
A) less resources, for example not enough RAM.
B) Racing conditions. On fast device task A always completes before task B, but on slow devices that can be different.
C) hardware incapability.

First of all, when you open browser console, do you see any errors and warnings? You can connect your android to PC and have for example chrome console connect to your device and see logs in real time.
Second, have you tried building in develop mode and see if there is any differences?
Third I would suggest connect profiler and see more precisely, but on android it will be harder. So instead try running memory profiler on your webgl version on pc, and tell me the how much memory does your game eats.

Last one is a long shot, is your background is black maybe by default? As there are some instances when touch on webgl returns values that is very unexpected. For example you epect values between -1 and 1 yet webgl returns you 124 or -800 or something. That can cause errors in your code or send camera really really far away somewhere and it just looks black. I suggest have FPS meter always running to see if game froze it self.

Seeya Later I hope that will give you clues to this weird problem.

[plain willow]

While i m building WebGL the site opening but the game is not, it is being white screen and console writes me "saving has no effect. your class 'unityeditor.webgl.httpservereditorwrapper' is missing the filepathattribute. use this attribute to specify where to save your scriptablesingleton. only call save() and use this attribute if you want your state to survive between sessions of unity. unityeditor.buildplayerwindow:buildplayerandrun ()" i m searching this everywhere but couldn't solve it

[brittle cargo]

Can you recreate that in an emulator to see if android version has anything to do with it

[plain willow]

I tried for windows and dont have any problem with it

Should i go for Android?

Actually i m new for unity and this project came to me , i didnt make this and i m trying to solve this problem cause i need to make this project WebGL

[brittle cargo]

Hmmm interesting, what network stuff does it do

[plain willow]

Normally i m making games in different editor

[plain willow]

What do you mean

Btw they sent me with api , api and project folder

[plain willow]

So i need to solve this error

[brittle cargo]

Like does it just call http requests or is it doing something with websockets or something more?

[plain willow]

http requests

this is the screen i get in site

this is the error i get

and still couldnt solve it

[brittle cargo]

Oh interesting what is this ScriptableSingleton

[plain willow]

Wish i could know

I searched every folder

[brittle cargo]

You have the project

[plain willow]

Every cs every script

But couldn't find it

[brittle cargo]

How did you search through scripts

IDE?

[plain willow]

Visual studio?

[brittle cargo]

Ah fine

Interesting

[plain willow]

And i tried to change unity version as well

But same error always

and the other error this as well so i m completly stuck

but exe is working 😂

so how can i solve this , anyone ?

[brittle cargo]

is there any reference to this getInternalformatParameter in the code?

also what are your webgl build settings

how are you serving it

[plain willow]

it is default

[brittle cargo]

i guess you can just open the index.html lol

[plain willow]

yes so here is the thing

oh and i tried itchio as well

not working 😂

[brittle cargo]

ahhh ok ok

interesting

ahhh lol this will work in firefox tho

[plain willow]

searched it and none

should i open this in firefox html ? or building ?

[brittle cargo]

your VS has the full project solution open right

[brittle cargo]

open the webgl build html in firefox

[plain willow]

yep ofc

let me try

[brittle cargo]

does firefox open the webgl?

[plain willow]

yep it did

[brittle cargo]

does it work?

like, the game itself

(it should if SSL is handled correctly)

[plain willow]

trying rn

nope still not working

[brittle cargo]

what part?

[plain willow]

seems like not

[brittle cargo]

latest firefox version? what is your videocard?

[plain willow]

gtx 1050

but videocard is not the problem

i tried in 4060 ti as well

same error

[brittle cargo]

yeah 1050 has driver level webgl support

very interesting

[plain willow]

and the funny thing is when i create blank project

it works and openıng

[brittle cargo]

well of course

[plain willow]

but this project has problem and i cant find it

this is the project btw 😂

[brittle cargo]

that's normal

[plain willow]

this is build

[brittle cargo]

most of it is editor cache

i have a small 2D game which at one point had a 20GB project folder

[plain willow]

oh i tried to clean and rebuild again

[brittle cargo]

nah that wouldn't help

[plain willow]

and i tried delete library and re opened

didnt work as well

[brittle cargo]

nah those kinds of fixes are for extremely specific problems

[plain willow]

i just wonder

is this normal

this much folder ?

[brittle cargo]

in the webgl build?

[plain willow]

cause when i see in videos there are less then this

yes

this is webgl build

[plain willow]

yes something exactly wrong with me building settings

let me send you wait

[brittle cargo]

but my project is literally just empty scenes with code generating UI for each scene

[plain willow]

oh

well still i didnt change any building setting

can you help me if it is okay

this is default i guess

[brittle cargo]

try to see if disabled compression changes anything

[plain willow]

tried it

[brittle cargo]

i couldn't get either brotli or gzip to work for the life of me

[plain willow]

😂 but let me try again

[brittle cargo]

but it usually shows if that is the problem

[plain willow]

before try that should i delete the one i builded

[brittle cargo]

you can but it should overwrite

[plain willow]

so it can work if it is on build ?

[brittle cargo]

wdym

[plain willow]

should i write on this

or should i build in different folder

[brittle cargo]

keep in mind i can't do much without access to the project itself : D

[brittle cargo]

doesn't really matter

unless you want to keep the old build

[plain willow]

should i change here ?

[brittle cargo]

you can try development build

to see if it changes anything (unlikely but worth a try?)

[plain willow]

yep why not

btw what if project connects to api ?

[brittle cargo]

then it connects to api

no problem

development builds usually build quickly and run poorly because they donh't implement various optimizations under the hood

[plain willow]

but what if i dont make them connect?

cause i didnt

cause i dont know how to connect api and unity :d

[brittle cargo]

think of unity as a frontend application

for example

        {
            _messageLabel.text = "Logging in...";

            var url = $"{Globals.AuthServer}/api/auth/login";

            var loginRequest = new LoginRequest
            {
                username = username,
                password = password
            };

            var jsonData = JsonUtility.ToJson(loginRequest);

            var request = HttpClient.CreatePost(url, jsonData);
            request.downloadHandler = new DownloadHandlerBuffer();
            request.SetRequestHeader("Content-Type", "application/json");

            yield return request.SendWebRequest();

            if (request.result is UnityWebRequest.Result.ConnectionError or UnityWebRequest.Result.ProtocolError)
            {
                _messageLabel.text = "Error: " + request.result + "\n" + request.error;
                if (!request.error.Contains("404")) yield break;
                _showRegistration = true;
                Generate();
            }
            else
            {
                var loginResponse = JsonUtility.FromJson<LoginResponse>(request.downloadHandler.text);

                if (!string.IsNullOrEmpty(loginResponse.token))
                {
                    PlayerPrefs.SetString(Globals.AuthTokenColumn, loginResponse.token);
                    PlayerPrefs.Save();
                    _messageLabel.text = "Login successful!";
                    StartCoroutine(FetchUserInfo());
                }
                else
                {
                    _messageLabel.text = "Login failed: Invalid credentials.";
                }
            }
        }

I have this login method, it simply calls my Auth API

i have this httpclient wrapper for unitywebrequests to add auth token to each of my api calls:

            string method = UnityWebRequest.kHttpVerbGET)
        {
            var request = new UnityWebRequest(url, method)
            {
                downloadHandler = new DownloadHandlerBuffer(),
            };
            var authToken = PlayerPrefs.GetString(Globals.AuthTokenColumn);
            if (!string.IsNullOrEmpty(authToken))
            {
                request.SetRequestHeader("Authorization", "Bearer " + authToken);
            }

            return request;
        }

        public static UnityWebRequest CreatePost(string url, string jsonData)
        {
            var request = Create(url, UnityWebRequest.kHttpVerbPOST);
            var bodyRaw = System.Text.Encoding.UTF8.GetBytes(jsonData);
            request.uploadHandler = new UploadHandlerRaw(bodyRaw);
            request.SetRequestHeader("Content-Type", "application/json");
            return request;
        }

so it's really all in the code

[plain willow]

so i can write that as well but how

are you free if i share you screen

[brittle cargo]

it should already exist in the code of your unity project

if it has any form of api integration

search for new UnityWebRequest

[plain willow]

well i did but that api i couldnt make that work

[brittle cargo]

why not

and what did you try?

how would you test an API?

[plain willow]

well i opened api in visual studio

and started .d

and then i tried to add to unity project

i did but still couldnt connect it

api there but

i wonder if it is working .d

[brittle cargo]

no you don't need to add the api project to the unity solution

the api is a separate application

running on some server

[plain willow]

yes i tried that as well

[brittle cargo]

you have both the unity project and the api of the game?

so basically the entire source code?

[plain willow]

yes

entire source code on my hand but i couldnt build for webgl .d

funny right 😂

[brittle cargo]

i mean

how long have you worked with unity

and how long have you worked with webdev

[plain willow]

3 days for unity 1 day for web dev 😂 but 4 years for ue

but i need to make this happen i have no other way

and i have 3 days so i searched everywhere over internet

[brittle cargo]

probably nothing in ue you did had anything to do with online integration

[plain willow]

yes exactly

[brittle cargo]

don't be so hard on yourself

you are basically a junior for this stuff even if you have good logic crunching skill from ue

alright so your task is to make a unity project work on webgl yes?

[plain willow]

yes

[brittle cargo]

so what you need is a build that functions in webgl just as it would in say android or windows builds

[plain willow]

yes exactly

[brittle cargo]

can you do a clean pull of the unity project?

so just clean from repo

[plain willow]

i m doing actually

[brittle cargo]

ok you know git, good

[plain willow]

so will be 2 different folder

1 will be game and one will be for api

right ?

[astral wave]

I agree on that, WebGL is nasty beast. It have a lot of caviats that dont work on it.

I would suggest you to start debuging step by step. First create new scene and include only new scene in a abuild. it can be emty scene. Build and run, see if that runs. This would show if your project settings or template is incorrect. After that you can work with searching other things.

[plain willow]

i will not mix them

[brittle cargo]

do not mix them

also you don't need the api for this step

you just won't be able to log in or whatever

we'll worry about that later

[plain willow]

okay

[brittle cargo]

ooooh this is good advice

[plain willow]

i tried it

and that runs

[brittle cargo]

But yeah webgl is %#]!¥<

[plain willow]

but this project doesnt

[brittle cargo]

No no

Create a new scene in this broken project

And in build settings enable only that new scene

[plain willow]

okay give me a sec waiting for opening

[plain willow]

alright

should i delete the main scene in build settings??

or just disable?

[brittle cargo]

Disable for now

[plain willow]

okay

[brittle cargo]

All of em except the new one

[plain willow]

well there is only one already so np

i will just disable that

[brittle cargo]

Only one scene?

[plain willow]

yess one scene but many things

[brittle cargo]

i guess that's doable

hmm, that gives me an idea to remake my project to be single scene

i already generate ui purely via code

[plain willow]

😂

[brittle cargo]

nah I mean this would be kinda like a single page application

[plain willow]

btw should i connect project to cloud ?

[brittle cargo]

i've never done that

git is my cloud

[plain willow]

well i event tried that as well

i opened git cloud in vs and didnt work as well 😂

waiting still

it wil open in 5 min

Well i liked unity after if we can solve this i will start learning unity from bottom

New challanges needed

[astral wave]

for this you need to run build and run. Rather than opening index html. At least in chrome. you need to disable some flags in order to load it otherwise. I think same goes for firefox, you need change settings to support it.

[brittle cargo]

yeah tbh i had a bunch of settings changed in firefox so mine isn't the default

[plain willow]

tried that as well

[brittle cargo]

and that was long enough ago i don't remember any of that

[plain willow]

opened switching platform

i tried everything over internet

before ask anyone

here is my last hope

[astral wave]

I jsut trying to catch up and adding some extra info. Also you might want to try building developer version and connect profiler to it, so you could see more precise which code causes the problem, if it that is the code problem.

[plain willow]

i tried different build settings etc.

[astral wave]

You said it uses API and was build not as webgl target platform. Are you sure there is not websockets code or other WebGL not supported code? Or multithreading like Jobs and etc. DOn't mind I am just firing blindly while waiting for emty scene build results 😄

[plain willow]

well there is leaderboard in this game

🤔

[astral wave]

So next thing you can try after testing emty scene. Disable some game objects that have features you can modulary disable. Try if that works on editor. Then build it. And then enable one by one and see where it will break. That will take tons of time, so make sure to build in developer mode to make it faster.

[brittle cargo]

i need to quickly implement something with websockets

[plain willow]

so should i say yes to this

[astral wave]

you will need to use UnityWebrequests or simple websocket package, the sockets.io doesnt work on weblg.

[astral wave]

oh you have adressables in your project.... you know how to use them riiiight?

[brittle cargo]

I already use UnityWebRequests for https

[plain willow]

ofc not 😂

how can i know

[brittle cargo]

got this set up, very comfy

seems to work fine on both webgl and android

[astral wave]

so in short. Adressables makes your game assets in to packages. sort of. So everytime you change something, depending on your settings, you need to rebuild addressables before building game project it self, otherwise changes will not be there. so make sure to build addressables before building project.

[astral wave]

seems nice 🙂

[plain willow]

oh wait so before i build

i have to build adressables ?

[astral wave]

yes. and everytime you change anything that is included in addressables you need to rebuild addressables before build.

[plain willow]

well i didnt change anything except adding new scene 😂

[plain willow]

rn

i see i just checked how to build addressables i didnt try that , maybe before i build i should build addressables

[brittle cargo]

bro what

ahhh it's a non default package

[plain willow]

okay i builded addressables

and now building new scene lets see

what will happen

maybe i should have gone with main scene

🤔

it is like this btw 🤔

[brittle cargo]

idk anything about this 💀

[plain willow]

everything in here 😂 yes the problem is this

i m pretty sure problem is this one

but lets see

[astral wave]

what is in Build In Data. As here it seems only localisation, which should not effect anything too much.

[plain willow]

well all game in here actually

localization , what is that ? is it different thing ?

[brittle cargo]

localization is basically what allows multi language support

[astral wave]

localisation mean it will choose different code, mostly text for different locations. Like in tukey it will be turkish, in spain spanish and etc.

[plain willow]

ohhh than this is not problem

this is just language

[brittle cargo]

localization assets are usually just a bunch of strings in different languages

[plain willow]

🥲

almost done building

lets see

[brittle cargo]

webgl builds are slow as hell

i need 16 cores 😦

[plain willow]

hell yeah

[plain willow]

maybe 5 minutes more 😂

[brittle cargo]

damn

[plain willow]

now 3 more min

he is bigger than most children 😂

[brittle cargo]

man it's almost 8

[plain willow]

but still working ue5

alright new scene is working

and error is still here btw 😂

[astral wave]

good. Time to disable everything and build alot of times enable thigns one by one. Dont forget to build as developer mode o make it faster. and change build type for build speed

[plain willow]

oh

okay

[brittle cargo]

damn i ran a build for my project with shorter build time

took a bit under 1min 30s

but remember my project is literally just six scenes like this

[plain willow]

which one i will selecet?

hand or eye?

[plain willow]

wow

[brittle cargo]

it's in its early stages and i have to set up a lot of ui

a bit under 1200 lines of cs code

[plain willow]

Optimized

[brittle cargo]

early

no gameplay ui done yet

[astral wave]

have you tried UI toolkit. If you like handleling UI via code that is kinda nice addition to UI. Need to learn a lot at the begining, but later is quite fun.

[brittle cargo]

UI toolkit is exactly why I'm doing purely code UI

[plain willow]

🤔

[brittle cargo]

check out my helper methods

[astral wave]

i dont even know where you find that icons 😄

[brittle cargo]

(yes, I know I can use uss, I use it too)

[plain willow]

well you said disable it

i dont know how to disable 😂

is it same in ue

[brittle cargo]

yeah i'd say about now i'm finally feeling comfortable with it

had a few good days with it

[plain willow]

oh shoot

[astral wave]

unchecking it will disable it.

[plain willow]

okay it is easier

[brittle cargo]

i'm now at the point where i can write ui elements (like for example a slider + text) from start to finish without once checking how it looks and it comes out exactly as i wanted it

definitely not at any advanced level where i can make crazy geometry with uss

I really like UI toolkit because of how easy stuff like this is

my game will be very heavily based around UI for interaction so I'm pretty pumped having finally somewhat grasped it

ngl it was tough at first because I tried to do with via the ui builder rather than code first/code only

it was such a pain fiddling around with the ui builder

ah but this is better for #🧰┃ui-toolkit my bad

[plain willow]

okay started to disable everything

lets see if it works

that means while everything disable it works right ?

😂

[astral wave]

thats good news. now you just enable one by one and see where it stips working 🙂

[plain willow]

finally something happenniingg !!

[brittle cargo]

niiiiiiiiiiicce

easy

so it was just addressables huh

i can totally believe that

[plain willow]

i guess i found the problem

but this one is funny

😂

[brittle cargo]

very typical

[plain willow]

everythin enable except 1 thing

and working

😂

windmill

the model

this one how can be possible

[brittle cargo]

did you redo the addressables build

[plain willow]

no no no addressables build

i didnt do anything with it actully

should i search this mindmill in vs ?

[astral wave]

welcome to webgl. when you do nothing and it works, and when you do nothing and it doesnt work 😄

[plain willow]

😂 you are welcome

[astral wave]

first try running it with it enabled to be 100% sure it is its problem

[plain willow]

well how can i solve that

there are 3 lod here

probably problem is here

lets see

trying without it

then there is no problem with code

the problem was lightning always

so the problem is exact this one how can i solve this

i cant believe that was the problem all the time

so okay we solved this but how can i connect api

there are requests

but i think thats enough for today i will research for that

still thank you so much guys both of you

🙏

[astral wave]

API connection is literally just UnityWebRequests POST and GET requests. Just as our friend showed before 🙂 you might need to work with CORS settings and etc, but that is for laters.

[plain willow]

well i dont have much time actually

and there are codes already written and ready

i just dont know how to activate api 😂

cause as i said it was working in exe

so it has to be connected right ?

[astral wave]

it depends on how you API is created. And how you connect. Some API establishes connection and keeps it. others just sends information when needed. I can't answer this question for you without seeing code.

[plain willow]

It is sending information when needed

[astral wave]

have you confirmed it sends data with logs? does error handling states that anything goes bad? No logs? Are you using unity web requests?

[plain willow]

let me send you the codes that use httprequest

this is my api opened one @astral wave

i thought this means sending information

and login not working
