[jade valve]

greetings. I have a UI sprite that shows F11 enables full screen. When in full screen, i want to swap the sprite to show that F11 leaves full screen.
Unfortunately, the code only works when NOT in full screen. When in full screen, the sprite swapping doesn't work.

I imagine this is due to the browser kind of owning F11

Is my best solution to code this into the index.html somehow?

[orchid bridge]

am i legally allowed to alter the template of the Unity WebGL text? (replacin it with something else) and changing the look so it doesn't show a Unity logo - apart from game startup?

[charred briar]

Yes there is a build in way to replace it too :).

[charred briar]

How are you making the change? You might be able to do it another way.

I'm suspecting there may be an event

[jade valve]

I'm just doing a sprite swap when F11 is pressed. And letting the browser automatically switch to and from full screen.

[charred briar]

Hmm.. It isn't the most performant... But you can check Screen.fullScreen

https://docs.unity3d.com/ScriptReference/Screen-fullScreen.html

You are definitely right about the other option, and sending a message using JavaScript from the web to the Unity blob

[acoustic plover]

Is there a timeline for when WebGPU will be available to use?

[sweet oriole]

Step one would be to see a lot more green in here https://caniuse.com/webgpu. I imagine moving to a more modern graphics API will become a pretty high priority once it sees implementation in browsers.

[wheat wadi]

Anybody who knows how to release mesh memory on WebGL?
I used Resources.UnloadUnusedAssets(); for releasing the mesh memory. But this is not working in WEBGL. And this makes out of memory error.

[nocturne oracle]

Hi guys i keep getting this when i play my game on itch.io how to fix

[wet grail]

Switch to supported compression or turn it off entirely. Itch has a guide for Unity which it support.

[drifting dove]

does anybody know any workarounds to this problem https://issuetracker.unity3d.com/issues/webgl-the-message-header-is-corrupted-and-for-security-reasons-connection-will-be-terminated-dot-errors ? Can't believe it has been more than half an year and they haven't fixed this

[dusty mauve]

Hey I got a Problem where Unity Wasm wont run a Methode inside a Thread or not get there. In Editior everything works fine... Do I have to activate Multithreading or anything?

[sweet oriole]

Unity C# threads are not supported at all on browsers atm.. Unity is working on engine multithreading, which is what that multithreading setting you may see talk about is for.

[dusty mauve]

Mhm what can I do I use the edge browser

And I used System.Threading

[sweet oriole]

Remove use of System.Threading

[dusty mauve]

Well is there another Unity way of threading

I need it for my UDP connection

[sweet oriole]

Do you just need it for async stuff or do you actually need threads?

[dusty mauve]

Yea I do need threads

I got a websocket connection and a udp connection

[sweet oriole]

Why do you need a thread for that?

Your UDP connection is also probably not going to work

[dusty mauve]

Why?

[sweet oriole]

I don't think browsers really have network APIs for UDP connections

[dusty mauve]

How would sockets work then

I mean to support tcp but not udp would be pretty weird

[sweet oriole]

I don't think you can just use TCP sockets either

Afaik you need to go through browser's networking APIs, like WebSockets or WebRTC.

[dusty mauve]

:/

[sweet oriole]

The realtime browser networking you see today is most likely WebSocket TCP.

[dusty mauve]

I hate web development

[burnt heart]

morning all! hope everyone is well 🙂

having an issue with hosting my WebGL game using NGINX. I have another game hosted with the exact same proxy setup, but I'm getting this on my newest game. The header is set in the proxy settings, and it's all the exact same as my previous games proxy, so not sure what's going on. Can someone shed some light on this please?

[astral wave]

change to disabled and then it will work. But i suggest to setup your webserver to be able read brotli or gzip

[burnt heart]

It’s already disabled as our server has issues serving brotli/gzip even when configured correctly

I had to enable decompression fallback to resolve this

Fixed as of like 11 hours ago, just forgot to remove post or say lol

[astral wave]

then your build wont have wasm. most likely you stil have old js for loading your files in index.html

[burnt heart]

Thanks tho

[astral wave]

oh nwm then 😄 glad it works 😄

[burnt heart]

I did a clean build after changing build settings, so it should only have what it actually needs 😛

[jolly yoke]

Hey guys for the unity play, I'm trying to tag the tutorial I used for the project I created so others can go to it if they want to try making their own.

The create and publish builds tutorial says you can tag tutorials but I'm not seeing where. I tried doing it where you can add asset packs but doesn't seem to work. Is there a different space?

it seems like the assets i'm trying to tag arent saving either - I hit save down at the bottom but doesn't show up on the project page

[sweet oriole]

I would just try again later and clear browser cache to see if it fixes itself. Could report a bug and post on the forum to ping Unity about it, though no idea if Unity Play is an active project of Unity anymore.

[arctic rose]

Did you check the console?

ok then

you don't say

show what they are

[orchid bridge]

Yeah, this server requires you to show what they are.

If you're still having trouble with them.

[high patrol]

What does that multithreading checkbox setting enable you to do then?

I'm assuming they're still working on error handling and haven't opened up anything in system.threading yet

[astral wave]

multithreading where?

[sweet oriole]

I don't think this checkbox is a thing in newer versions of Unity? It's also a bit misleading since I think it ended up being just C/C++ threads of the engine.
More details can be found in these threads:
https://forum.unity.com/threads/multithreading-and-webgl.817986/
https://forum.unity.com/threads/async-await-and-webgl-builds.472994/

[astral wave]

you must have these links on speed dial 😄

[sweet oriole]

Open tabs from a previous convo I had on code-advanced 😄

[silk brook]

now I really need to know how to set a full screen on default
not the full screen button like F11
but fit in on the browser window ...

[sweet oriole]

You do it the same way you resize other divs in HTML. Unity by default matches the whatever size the canvas ends up having.

[silk brook]

but maybe here ?

[sweet oriole]

Settings involving specific numbers are probably not relevant if you want to scale based on something else, like window size.

Edit the HTML output

[silk brook]

ok let me find out can you suggest me some google keyword tutorial ?
never did this before tbh

[sweet oriole]

IIRC you should see style="width: ..." stuff in the default output, so my tip here would be that you can replace px values with % values.

Browser inspector views are great for finding out (and modifying for testing) what values are being applied to your elements.

[charred briar]

Application.fullscreen = true; works on WebGL

[sweet oriole]

I assumed they meant just the size of the page with this

not the full screen button like F11
but fit in on the browser window

[charred briar]

Fair point, I misread it as trying to bypass needing to press the key

And yup, width and height 100% on the canvas does work with Unitys WebGL (not with Phaser though which is interesting)

[sweet oriole]

Yea it seems like the "app" is partially responsible to handle the scaling and I guess the canvas system doesn't stretch content by default?

[silk brook]

where should I put this line code ?
on .json file ?

[silk brook]

some canvas U.I did to stretch content by default

[sweet oriole]

To be clear, meant the browser canvas system, not the Unity's canvas system.

[sweet oriole]

It's just C# code. You can put it anywhere where it will execute

[silk brook]

plan to put it on the very first instantiate

[sharp bramble]

Hello, i am trying to build for webgl this is the first time i am doing that and have an error right now Unable to parse Build/PTBTD.framework.js.br! This can happen if build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present. Check browser Console and Devtools Network tab to debug.
What are the things i have to change for it to work?

[sweet oriole]

How you configure the host depends on the hosting solution. Unity documentation has configs for some cases.
If you don't mind a lot bigger build size, you can disable build compression or enable the compression fallback in player settings.

[sharp bramble]

i don't think so, where can i find these settings?

[sweet oriole]

Which settings?

Player settings: https://docs.unity3d.com/Manual/class-PlayerSettings.html
WebGL player settings https://docs.unity3d.com/Manual/class-PlayerSettingsWebGL.html

[sharp bramble]

like the hosting configuration

[sharp bramble]

I got it working with the build size settings

[sweet oriole]

Again, depends on the host. These are not controlled by Unity.

[sharp bramble]

I am hosting it on itch.io but it works now

[jolly yoke]

hey guys having an issue publishing my next project from the learn platform.

Gets stuck at 90%. Tried disabling compression on the player as per guide on searching about this issue, compression was already off tho. Any other ideas why loading the game gets stuck at 90%?

Seems to run fine on localhost

https://play.unity.com/p/webgl-builds-227847/

[quiet lagoon]

Any way to disable all these warnings in the console?

[astral wave]

I am not 100% sure but maybe these two?

in player settings in build options

[quiet lagoon]

thank you, but the output in console still remains

[astral wave]

is build developer mode or not?

[quiet lagoon]

no, release :/

[sweet oriole]

Try redefining the methods to the browser console in JS 😎

[vivid trench]

Hello. I'm sure this has been asked to death but I couldnt find good info:

whats the webgl version of this statement?
path = EditorUtility.OpenFilePanel("Select an image", "", "png,bmp,jpg");

I just need to let the user select a file. doesn't need to go to a server, it's all client side.

Thank you

[sweet oriole]

Unity doesn't a built-in file browser handling. Look into this: https://github.com/yasirkula/UnitySimpleFileBrowser

[fluid lily]

Hey everybody, first time using unity for webgl. If you have a game that runs in a website and needs to run complex javascript code that affects the server state. How do you set it up so you can test from the editor without having to make builds all the time?

[orchid bridge]

My WebGL build has been loading for 30 minutes
Last time I made a build it took about 8 minutes
In the task manager I noticed that the build folder is not responding

I tried to cancel it but that isn’t loading either
Should I force end it? That’s not going to corrupt data or something is it?

For my last build one of the materials wasnt appearing and I found a tip to turn on Decompression Fallback
I haven’t tested if this works yet

I found another tip that said set compression format to disabled, is this good advive?

[high patrol]

there isn't a debugger for webgl. you have to use the browser's console output (place lots of debug.logs)

[river tinsel]

My WebGL build keeps failing with these errors : https://pastebin.com/TGjuGs7p
It works fine on windows standalone however I keep getting the same error here.
I've tried changing the project/ build path, restarting my PC/Unity, reinstalling Unity (2021.3.7).
Anyone know what I could be missing?

[vivid trench]

Hi guys.

So i got this jslib file with a function I want to call, I call it from my C# code and get EntryPointNotFoundException: myFunctionName

        yield return image;

        if(image.result == UnityWebRequest.Result.ConnectionError || image.result == UnityWebRequest.Result.ProtocolError)

    }
 
    public void OnButtonPointerDown (BaseEventData data) {
        ImageUploaderCaptureClick ();
    }
}

the 2nd to last line of this code gives the error: EntryPointNotFoundException: ImageUploaderCaptureClick

[charred briar]

The second last line of code is a }

And you posted two different code snippits.

But that is saying whatever DLL you are using doesn't have that function in it - or at least not in an accessible way

I'd venture a guess it's because ImageUploaderCaptureClick is not explicitly a function

See the declarations here for an example:
https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html

The other possibility is the plugin isn't set to WebGL

[strange hollow]

How do I use mirror networking with webgl? Are there any tutorials? Cause I can't find anything.

[astral wave]

https://mirror-networking.gitbook.io/docs/transports/websockets-transport

[indigo sail]

Hi. How can I split data from build.data.gz? I need to reduce file size to 200 mb for itch download

[sweet oriole]

You can use Addressables. Generally you don't really want to approach that number just to play the game.

[silk brook]

it's common to happen, but never really2 stop at 90% it goes through
try another Unity version might results better
or Unity WebGL Publisher

[jolly yoke]

Thank you I'll keep that noted. What worked for me this time was to enable player compression to brutli

[silk brook]

did you build it using Unity WebGL Publisher ? @jolly yoke
since no one use brutli on a stand alone WebGL build

[jolly yoke]

Yeah i came to that answer through forums. Built it first, then selected that build in the publisher. It was for that unity learn assignment and to have it work that's what I needed to do. Is there something newer?

[sweet oriole]

Brotli offers the best compression with very little drawbacks that I'm aware of. I imagine most serious Unity WebGL developers are using it.

Pretty sure WebGL Publisher exists just to easily push builds to Unity Play.

[worn blade]

Hi! I'm building to webgl but i'm struggling

i have theses files

what do I have to upload ?

[austere meteor]

Im trying to run a webgl game on itch, but when I run it it shows this error:
Unable to parse Build/SpecialKingWebgl.framework.js.br! This can happen if build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present. Check browser Console and Devtools Network tab to debug.
In the console i get this error:

It doesent get an error when running it on local host

[half parrot]

so I spent today writing a music management system, got it all working in editor, worked out most of the bugs... made a webGL build, and its having some weird issues in the browser version, and I have no idea how to even begin troubleshooting them

how do you debug for issues that are only happening in the webGL build and not in the editor

like, I know this doesnt help solve the issue at all, but here is what I'm dealing with:

In the webGL build, if I start the game, then return to title screen, then load back in the game... the music volume is 0... if I go into my pause menu and adjust the music volume, it instantly comes back. This is consistent and reproducable 100% of the time

but this does not happen in editor, only in the webGL build

[astral wave]

Unity people who worked on this

WebGL: Fixed connection between the WebGL player and the profiler. (UUM-798)

WebGL: Fixed player connection used when running PlayMode tests on WebGL. (UUM-1170)

THANK YOU ❤️ waited for this for so long, best update ever!

[half parrot]

OH, I know what the issue is... and I think I know how to address it

its cause I'm using a dictionary in a scriptable object with an <enum, AudioClip> pairing... thats all well and good, but in order to initialize it properly and make it work in editor, I am populating the dictionary OnValidate

I need to copy that code over to Awake so it runs when the game starts in browser

I hope that fixes it... but I'm not 100% sure it will

[cosmic crown]

is there a way to have the browser ignore ctrl+F ?

@astral wave thanks, i did exactly that in my webgl template

Guys im exporting a WebGL app for integrate with a platform named Adform, when i import my app this cast an error

[orchid bridge]

Maybe try with Xampp for run a local server

Or can i replace the loader.js with another method?

[river plaza]

uploaded a thing to itch io on 2021.3.8f1. there is no compression enabled

[river plaza]

any help?

[astral wave]

well it states that you are trying to run compressed build, which is compression. In player options:

1. disable compression, no gzip or brotli.

2. Enable decompression fallback

3. Check your index.HTML file. you might be loading old Build files instead of new build file\s.

[river plaza]

alright thanks, I will try that

[astral wave]

https://docs.unity3d.com/Manual/webgl-deploying.html
Also I suggest dont have folder with spaces. As they will name files after build folder location. Sometimes it can cause problem.
and the problem is that trying to load compressed file instead of non compressed. you can easily check in your build files how it looks by the name
build.framework.js.br -> build.framework.js

[rare kettle]

Hey everyone! I'm trying to get a CSV generated from my Unity project and push it to the React website the Unity project is located on. Currently, I have the file written to Application.persistentDataPath

You can transfer it as bytes or a string to the JS land through a jslib. https://docs.unity3d.com/2023.1/Documentation/Manual/webgl-interactingwithbrowserscripting.html

Hi, I'm hosting a WebGL game on a HTTP server, trying to use UnityWebRequest to access a HTTP API (Both were HTTP for testing). I'm getting this error whenever the game makes a call.

can somebody lend me a hand with this please? I've asked in about 3 servers now over the course of this week 😦

[twilit wigeon]

I tested out building my game for WebGL and noticed that the volume level settings for the audio clips weren't being used. All audio clips are playing back at full volume.

Do a development build and view the output log file to see what's breaking. You aren't going to get any useful information out of the browser console

Hi. I am trying get window properties if them exist. For example:

But if I use `?.` build fails.
Is there solution of this problem? Unity version 2021.3.6f1

[arctic rose]

In what situation would window not exist?

[indigo sail]

I write it for example

Real case is another

[arctic rose]

Well it would be nice if you asked about the real case instead of an imagined one

Is the variable you're trying to check a global variable?

[indigo sail]

I got build error in any situation when I use ?.

[arctic rose]

Yes, you said that. You can't use the ?. operator then.

[orchid bridge]

guys please i need help with this error

is for a job

[orchid bridge]

Well, i finally solved it, i will explain below if someone have the same issue:
i think that error occurs because is not compatible with HTTPS or HTTP Protocol and rules that have the Platform
so solution is simple: Upload to the platform a html that contains an iframe tag with the source of WebGL game, calling from a personal server

The platform that i tried to upload the source is named "Adform"

[silk brook]

how come it's not compatible ? @orchid bridge

[jolly flare]

hello guys i did a webgl build and uploaded a game to my website, and had issues, I can play the game on Firefox, and Microsoft Edge, but not on Chrome ><

[sweet oriole]

Might be one of your addons?

[jolly flare]

addons?

for the browser itself? i dont think im using any

eh i only had 2. some google documents thing and a google meet thing. i removed them both just in case

it just shows a grey screen. and nothing else

[jolly flare]

if i upload it to itch.io it can be viewed, but not on my personal website ><

[sweet oriole]

Yea browser addons. Try to make sure you are clearing your cache? Perhaps there is some cache control issue?

What do you have in browser console?

[jolly flare]

let me check

ok cool, yeah i saw an option for "allow unsafe code" or something, and checked it now its working just fine.

Ok so my next issue, i upgraded to unity 2022 and it says that it supports the mobile keyboard when you select an input field. i cant find the API to enable the keyboard when the input field is selected, does anyone know where i can find it?

[arctic rose]

There is no API. The keyboard opens automatically.

[jolly flare]

it is not 😦

[jolly flare]

Unity uses the Text mesh pro input fields by default, calling the old input fields "legacy". could that have something to do with it?

[charred briar]

Is 2022 out of beta?

Might just be a half baked feature in 2022 :)

[jolly flare]

*shrugs idk. i was just reading that they just integrated the mobile keyboard functionality with 2022 so i upgraded the project.

[proud owl]

If I was to make a small webgl game, how/where could I publish the game to make an ios user test it?

[burnt heart]

hi, getting this error on my built game.
call works completely fine in editor and using a REST client like Postman

CORS is enabled on the API too

using UnityWebRequest

[arctic rose]

Check the Network tab and see what it sends

[tranquil sable]

First time exporting to WebGL, deadline of the game jam is in <4hr
Anyone that knows what's wrong?

\

Please ping me if you have an answer!

[tranquil sable]

Got it fixed by doing the build uncompressed

[dim spade]

Does anybody here know how to stop unity WebGL builds from automatically hiding the mouse on any key inputs?

I'm using the new input system if that helps

[arctic rose]

It's OS/browser behavior, I don't think you can disable it

[astral wave]

I am sure that is not the case. I am using webgl and mouse is not hidden regardless of what you click. Maybe you are using starter assters first or third person character controller? as hiding mouse is a feature of them. Normaly mouse is not hidden

[mossy hamlet]

Hi ! Does anyone knows why some users have these errors? I try to upload it on itch.io and same thing as my server. Several browsers tested with no luck. I don't have this error on my side so I can't really reproduce it...

[pseudo sundial]

i am having a issue when i build my game for webgl the sprite image of player gets invisible but the game works perfect on windows and linux

[quiet lagoon]

Does any other sprites turn invisible? If you just add a component with a spriterenderer and nothing else to the scene and build, does it stay?

[arctic rose]

It's not a behavior in your OS or browser then. And nobody said anything about clicking.

[astral wave]

Well know for certain that StarterAssets third person controller uses Cursor.lockState = newState ? CursorLockMode.Locked : CursorLockMode.None; to make this behavior happen. Aka if you click your cursor is locked\

[arctic rose]

nobody said anything about clicking

[astral wave]

on any key inputs. How it is not click. Click is as key input as keybord....? If you game have disabled mouse, aka locked, clicking with mouse on game will go to Focus mode of your game (if not full screen), same can go with clicking any keyboard button (unless you WebGLInput.captureAllKeyboardInput = false;). As long your game have cursor locked it will keep happening. Anyways it is most likely because of character controller which do good job at locking cursor. And the moment webgl got html focus it starts working.

[arctic rose]

You don't "click" a keyboard, and a 3rd person controller obviously does nothing to input fields

and the behavior is the same on all websites whether they use Unity or not so it obviously has nothing to do with Unity

[elfin portal]

me confused

[mossy hamlet]

Is there a way to have some support here please?

Many users have this error

[astral wave]

Connect your profiler, and check memory usage. Most likely your game is using more Memory that device have available, here you get memory out of bounds problem. It all depends on device, browser. Some have limitations of 500Mb and etc.

[astral wave]

also to be sure you can build developer version with full stack , open console and see what script causes it

[mossy hamlet]

Thanks! I tried to analyse the Profiler but I don't really know how to look at it to find the issue or if it's a script or another part... there are so much things to analyze..

[astral wave]

provfiler is really difficult thing, I agree. but you can get used to it. There is also memory profiler, which gives more simple data aboout memory. Quick question, as this webgl project, are you using Addressables? and how big is your game?

[mossy hamlet]

Addressables.. ? the final folder is around 130MB. I already reduced all the textures and images that I could and changed also some big image in a square format (512, 1024 or 2048) and I also used the "overwrite for WebGL" function when I was able to

[astral wave]

Well, then you need to add that to your project, it can do wonders if you have multiple scenes and etc. Also use textures compression crunch mode, make sure your textures have correct format. Tho if you will use addressables yo uwill have problems with shaders then 😄 just fare warning. But with that project size, I bet you can be used over 1,5gb memory without problems

[mossy hamlet]

There is only 1 scene in this project but yeah If I understand a little bit the Profiler, I see 1.36GB In use / 2.10GB reserved

[astral wave]

Have in mind that profiler in Editor and profiler in Standalone will give VERY different results. But I asume you want to run your game on Phones. So if you want to run it at IphoneXr (4gb memory), you need to consume less than 500 MB preferebly. If it goes higher there is high possibility you will see that error. At least that what I learned from my experience

[mossy hamlet]

but some users had also the error on Desktop in 3 different browsers

[astral wave]

Do you have access to get more information from them? without console data you wont be able to add anything else. You really need more information than just that error. Console data, degus line, comnputer specs and etc. it could also be your old build problem, just htye have cache of that game or something

[mossy hamlet]

I try to build a new version with the Clean build option, but still the same. It will be difficult to have all the info from each users.. but to resume, it's a memory issue then..

I tried many things in the PlayerSettings like changing the compression, the quality, Net 2.0 instead of 2.1, still the same

[astral wave]

That is my first guess. As you get that error either when you run out of memory. Or when one of your arrays tries to access data from incorrect Key. At least from my experience.

Thing is you really need to get access to a way to reproduce that error your self. In controller enviroment. also you could just build developer build with full stact trace, and let people join for a while,and ask someone with error to open browser console and send you error code. as then if it is script error, it will give you exact line of error.

So you have two steps now:

1. Login with same acount, or same data as person who have the problem (as it can be data problem)
2. Find a way to cause that error your self. Limit your browser memory or something just to trigger it,
3. Get device close to people who had problems. And collect that data.

as if your pc users all had chrome books, no wonder it had that error. but if one of them had Gaming pc...... you can then start investigating your code with arrays and stuff.

[mossy hamlet]

Thank you for your help! I will send that to my dev and we will check everything

[jade valve]

I've made a UI scroll wheel. Works great in editor. On webGL build, it works very poorly. But, if I open the console window. It works perfectly. Any ideas why?

[astral wave]

My guess something with frames. As webgl have locked frame rate anyways, maybe something with script goes unwell. I suggest manually lock frame rate in your game and try again. Maybe change from update to late update or something like that as well, fixed update. text things out

autoconnect profiler does not seems to work with Https. any suggestions? or shoudl I report is as a bug.

[pseudo sundial]

Only my one player sprite is not visible idk why

[jolly flare]

Hello guys. How do I get webgl to work on Google Chrome on mobile? I was getting it on pc but I did the allow "unsafe" code in the setting and it works pc. Doesn't work on mobile.

[jolly flare]

ok i got it in the debug window it is giving me an 'out of memory" error.

ok nevermind i fixed it, apparently i had too much memory alocated

[mossy hamlet]

how did you fix it exactly?

[jolly flare]

@mossy hamlet initially I had ythe allocated memory set to 1024. I reduced it back down to 32mb, and it fixed it. Apparently my phone only has 2gb, and it was causing it yto max out memory during loading.

[mossy hamlet]

and where did you change the allocated memory? I have a big issue with iPhone for my project too...

[jolly flare]

It's in the project setting under publish if I remember off the top of my head.

Project settings>player>publish settings.

[mossy hamlet]

In Publish Settings, I see the compression, Enable Exceptions etc.. but nothing for the memory

[astral wave]

It is because of your Unity version. Memory allocation was added not so long ago. If you will be using 2022.1.12 you will find it here. It most definently not exist in 2019, and I think it was added in 2022... not 100% sure tho, but just remember we moved to 2022 because webgl have more stuff there.

[mossy hamlet]

ho ok.. I'm using the 2021 and there is nothing there

Any other settings to check for the Allocated Memory in 2021?

[astral wave]

As far as I know - No. You can work around using addressables and managing what you load to memory manually, so it wouldnt use too much.

[mossy hamlet]

What is Addressables..?

[astral wave]

Addressables is Unity feature, whichs lets you handle what is loaded to memory. As by default, when you start your scene, EVERYTHING will be loaded. If you have multiple scenes, multiple scenes will be loaded. Addressables lets you load to memory only what you need. Then when you dont need, you can unload it and free memory. It will still stay in Storage (broweser cache) but not in memory. So performance wise it is very huge.

BUT... weblgl and adressables have some problems when it comes to shaders, as it tends to add load all shaders possible. Which can bloat mamory usage (it depends very much on project. Mine shaders usage increased to 200mb RAM.) But you can manage that by writing your own shader stripping code and solve that problem. (with shader strippign got back to 20 mb memory for all shaders).

anyways.... profiling profiling profiling.

[mossy hamlet]

seems complicated.. hehe thanks for your answer. Yeah we try to know what is the issue.. It's working on iPhone 11 but not on 12 or 13. Some Android have the same error too.

[astral wave]

Install memory profiler. Build dev version with autoconnect profiler option on. Create snapshot of memory usage. And you will see how much memory your game use. If you use anything more than 500 mb..... that will be no go... Iphone 10 I would say 200mb can barely move and crash sometimes for out of memory... so you need to aim even lower

IphoneXr brokes at about 500-600mb 100%

[mossy hamlet]

I've checked Memory Profiler but I didn't understand everything. There are a lot of parameters and I'm new in Unity..

I will try to build a version with dev mode. There is only 1 scene for now in our project

[mossy hamlet]

@astral wave Does this means that the project take 3.22GB in memory to run?

[orchid bridge]

l got this when l try to download unity webgl l got the error and he got stuck at the end l try everytime but its not working and l use bolt

[deep topaz]

i'm having issues publishing a project with visual scripting and webGL, are there known compatibility issues there?

None of my inputs seem to work

[cloud ermine]

how to treat webgl build if it's end up with failed ?

[astral wave]

Please run memory profiler for your Built version, and not in editor. Editor data is very inaccurate and bloated,

but yeas that shows how much your application uses memory. In this case your application and editor I think.

if you will go to tap memory breakdown, you will see how much textures, shaders and scripts are using,. that is good start with optimising project.

[astral wave]

Well I see undefined symbol at at AddNumbers. It is worth checking there. Have in mind that WebGL build is more sensitive, so it checks all your JSlib files (aka plugins) to find any errors. and you have some. Have in mind, dont use ANY non english simbols inn your plugins code, even in comments.

[astral wave]

Step 1) Run hub as administrator
Step 2) Install unity version without WebGL feature. After it is installed, add webGl feature\

[mossy hamlet]

is it something outside of Unity? Because I've installed the Memory Profiler and I took a snapshot.. but that's it. I don't see how to use this tool then..

[astral wave]

In build options turn on Developer mode and turn on autoconnection profiler:

Press build and run. Then game will open in your browser. Open Memory profiler again and you will notice that instead of editor it will be connected to your game on webgl. Make snap shot again and you will have your build game data only.

[mossy hamlet]

Ho ok, this way. I was building with the Dev mode and autoconnection but I didn't know the part for the Memory Profiler. Thanks! I will try.

[quiet lagoon]

Can anyone explain why the quality of the game turns to shit when loading a webgl game on mobile or even responsive design mode in browser? If I just resize the browser manually to be the exact same resolution as a phone, then the quality is great. But the second it is a "mobile device", the quality goes down so much it's horrible. Even the "Made with Unity" splashscreen is terrible quality

Never mind, I figured it out. If anyone else needs the solution, change the "config.devicePixelRatio" in your index.html file to a larger number than 1. I changed it from 1 to 2, and now everything looks much better

[jolly flare]

Hello, so on my webgl build how do i make the screen rotate on mobile?

[cloud ermine]

wiping out the library and leave it regenerates wasn't work as well

[astral wave]

are you using any Javascript plugins in your project?

[astral wave]

https://code-boxx.com/lock-screen-orientation/
In short: you can rotate to landscape on mobile only in fullscreen mode. Java script code can do that automaticly. BUT you cannot go to fullscreen mode automaticly, user needs to click at least once to do so.

[webgl error > An abnormal situation has occurred: the PlayerLoop internal function has been called recursively]

So, I've been having an issue with my game. I'm using my own auth and when my game was on mono/windows build, everything worked 100% fine. However, when I switched to webgl I noticed that when I got to my login scene, it wouldn't auto log me in like it should, and when I entered my username/password and clicked "sign in" it wouldn't work and gave me this error: An abnormal situation has occurred: the PlayerLoop internal function has been called recursively.. Note, that error occurs when I run on local or from my website, all the features work if I run it from Unity Editor...

I also noticed that when I was building a windows build, if I switched to il2cpp from mono, the same issue would occur, obviously I didn't see An abnormal situation has occurred: the PlayerLoop internal function has been called recursively., since it was a windows build and not webgl, but still couldn't login.

Basically to sum it up, is it really il2cpp effecting my game login? if so, how do I go about fixing it? Thank you.

[astral wave]

If I remember correctly, webgl is always il2cpp type of build. And to be honest that is better. WebGL and il2cpp is way more sensitive when you have incorrect code left somewhere. Windows be like: well you dont use this line of code, so I dont really care. il2cpp: FIX THIS SHIT!!!!!!

Just build developer mode, with full stack trace and check what exactly causes this error. It can be jslib, it can be plugin. It can be as you doing something not over HTTPS (for webgl that is kinda a must for most things). Maybe you trying to access something that is not on same domain as webgl (also no go in webgl).

Or you can build on windows il2cpp and check build report to see what is the problem. It is expecially common when you have any javascript libraries. as Editor will not see anymistakes there until webgl build or il2cpp

[orchid bridge]

Yes, I noticed that webgl is only il2cpp, and the code is fine. It works on windows mono and on regular c# vs projects (login system)... everything is setup the way it should be so I'm not 100% sure what's going on exactly.

I tried to build in regular il2cpp before and it wasn't giving errors in the console... just wasn't working. But on webgl it gives error(s).

[astral wave]

Trust me, if it looks good... doesnt mean it is good. Once I got error that I used Kanji in comments on jslib file.

[orchid bridge]

The site/game is public if you want to take a look at the errors it is giving? or I can just send a pic?

[astral wave]

if you turn on webgl develop mode and turn off crash on error, it will work as in windows where you got error on ilc2cpp

[astral wave]

Does that build have developer mode and full stack trace on? otherwise error will not give a lot of info to me. \

[orchid bridge]

Give me a few, I have to reenable the login section. I had to remove it because it didn't want to work. One second, and I'll check the full stack trace.

[astral wave]

What login you are using? WEBrequest? php one? does login goes to same domain?

[orchid bridge]

Currently it's full without stacktrace, and release.

Also, the auth is built in php but I'm using c# api/class.

[astral wave]

Debug.Log Debug.Log and once more Debug.Log :DDDDDDDDDDDD

[orchid bridge]

I'm uploading updated version of game so I can show you all errors.

[astral wave]

Great, lets see if that will give us more data to help u

[orchid bridge]

So in console:

That's just when the game loads.

Then I enter username/pass and press "sign in" and get this:

[astral wave]

are you trying to use SocketIO?

aka you trying to connect dirrectly somewhere?\

aka System.Net.Sockets

[orchid bridge]

Just system.io

I need it so that the auth can initialize.

[astral wave]

What these logs dont give a lot of info. at least for me. Did you implement any fucntion called icall?
If you impelement something twice it can cauz problems.

Other reason is webgl limitations... and there are alot of them...

[orchid bridge]

Nope, everything is added once. No duplicates that I'm aware of.

[astral wave]

What are you accessing with system.io?

[orchid bridge]

FileStream and MemoryStream for encryption of data.

[astral wave]

Are you accesing files over UnityWebRequest from same domain as your webgl aplication? Or try to access something from your pc? or streaming assets?

[orchid bridge]

So I have a class called api... that is the c# class for all the auth functions.
Then I have a class called func... that is the class that calls the auth functions.
On Start,
I have init(); the process for init looks like this:

Everything is built in and the requests that are made are to the auths website.

So, I'm using an sdk.

[astral wave]

is this SDK is C#? or Javascript?

if it is C# and you try requesting something from different site/ domain. You wont get anywhere

Unless the creators of that SDK did somekind of magic, you cannot access anything from web gl that is not in your domain.

[orchid bridge]

The auth was created in php... there are multiple different sdks for the auth (C#, c++, php, py, etc)... I'm using the c# once since it's unity...

Using the same auth, it literally only works with windows build... or webgl build in the unity editor... webgl does not work locally or from my site.

I have all the files that the build provided me so it should be working just like everything else.

[astral wave]

webgl in editor is not webgl. Webgl in editor will be able to access everything without webgl limitations.

[orchid bridge]

I'm just telling you what works and what doesn't.

Webgl shouldn't be this difficult to work with. Makes 0 sense.

[astral wave]

AS working on webgl for 2 years I can confidently say.... IT IS WAY MORE DIFFICULT THAT IS SHOULD BE AND NO ONE SHOULD USE IT IN GENERAL.

Only choice you have is comment half of your code and then build again and again until you will find where it stops working. But my guess is that you request something not from your domain. We hade tons of problems with authentication, and ended up using API which takes data from authentication server, and passes that data from our domain API.

and when you request something u cant, you get error, and that error crashes your things. Normally if that would be just webrequest you would see that in error logs. but something goes wrong in authentication for u. Sorry I cant really help more, that saying limitations of webgl and how to search for more data on error.

[orchid bridge]

Well, I'll try to just disable all the auth functions then and see if the errors still persist or not.

Just odd it would work on other builds but not webgl... you'd think there would still be some sort of error or warning but nope... nothing.

[astral wave]

That is best approach, keep disabling features you can until you get it working.

[astral wave]

Welcome to webgl.... Trust me it is not the weirdest thing you will encounter.

[orchid bridge]

Wait... so you're saying it could be the auth not connecting/making request to domain properly so that's why it's not working... so see, I would think that's the case as well but I just remembered that even before I switched to webgl, I went from mono to il2cpp (windows) and had the same exact issue with the login scene... it wouldn't login and wouldn't auto login either.

Has to be something with il2cpp because it if was just webgl then I wouldn't have had the same thing happen on windows il2cpp build.

[astral wave]

You have a point there. (it still can be an error but still).

Lets approach it from this angle then. Lets make windows il2cpp build work (as it is way faster build times than WebGL).

[orchid bridge]

Now, I just tried to remove the init function for my auth so it wouldn't make a request and instantly got spammed with the same error 🤦‍♂️ ... so that's fun. Just keeps getting more and more odd.

[astral wave]

So core difference of il2cpp that is way more strict than mono. Could you try building windows il2cpp then check build report in

this will give you more data on error, maybe there will be a clue.

[orchid bridge]

Yeah, building now.

[astral wave]

while building please check if you have any jslib files in your plugins folder. Aslo... you project directory doesnt have any non english symbols riiiight?

[orchid bridge]

No, I do not have jslib files in my plugins folder and nope, no non English symbols.

[astral wave]

(╯°□°）╯︵ ┻━┻

[orchid bridge]

So I just built/ran il2cpp windows and it crashed when I pressed login..

[astral wave]

but the build were successfull O.o

WebGL build Problems

[rustic oriole]

Is there a faster way to see updates for web platform than build & run?

[orchid bridge]

Other than running from unity... I don't think so 🤔 .

[rustic oriole]

Dang, that's what I figured but wanted to doublecheck

[jolly yoke]

Hey guys, I'm having an issue packaging a 2D WebGL game I made - when previewing on unity play, it shows a gray screen and no audio.
Looking at the forums I re-assigned my canvases to scale by camera, adjusted player compression to brotli (the game gets stuck at 90% loading if this is not checked), selected the tag as MainCamera, and added all scenes to addcurrent but it still just says made with unity and then shows a gray screen. Any ideas or need additional info?

Really appreciate the time and help thank you

[astral wave]

you talking about Play mode in Unity? It sounds like you dont have no camera ON.

[jolly yoke]

does something else need on?

[jolly yoke]

^

[astral wave]

So In play mode everything works. Just doesnt on webgl build right? What rendering pipeline it is?

Not URP for sure.

[jolly yoke]

Honestly I'm not sure which one i selected when I started the project. is there a way to check and/or switch it?

[astral wave]

To change it you can do it from package manager by downloading Universal RP. I guess you are on default pipeline, as camera have almost no options 😄 I know that HDRP (High Definition RP) pipeline will not work on webgl, but IDK how it looks like just from camera settings. you can cahck in your package manager if you ahve it installed or not

[jolly yoke]

ill take a look rn tysm for ur help

was not installed so must have been default or HDR im not sure. Was just a small side project so didn't plan ahead

After doing some live learning sessions i'm starting to see URP is and should be the default in most scenarios in my case at least lol

[astral wave]

Have you tried to build windows version of it just to check if it works there?

Yes, URP is a way to go currently.

[jolly yoke]

I didn't - running pretty lightweight on the engine atm I would need to install the dependencies for windows. Have only been doing webgl so far

ill try this first. After I hit install do i need to go into settings somewhere?

[astral wave]

you will need to convert your materials to URP.location of that differs on your unity version:

this is 2022

are you using default Unity webgl template?

Also have you chacked browser Logs? is there any errors?

F12 on chrome

[jolly yoke]

which tab shows this area? cant find it

I havent tried running a webserver to test games locally either so im not sure if it would report logs without one

[astral wave]

You dont need webServer if you press build and run. it will create your own temporary webserver.

So then you got gray screen even on your play mode?

[jolly yoke]

no in play mode it works fine

just when trying to play in play.unity.com - uploading the project to my portfolio on there

[astral wave]

Try changing

this will make sureif it camera options or what. you can also just ppress build and play so you wont need to upload anywhere

[jolly yoke]

From forum advice i changed that from screen space overlay to the camera in the scene

was already at the overlay setting beforehand

im not sure if its just not loading the camera at all, theres music playing in the menu but the listener doesn't appear to work either. doesn't detect sound

[astral wave]

it very much sounds like there is no camera at all. But that does not explain why it does not exist only on webgl

do you have nay scripts tha controls camera?\

[jolly yoke]

There shouldn't be , camera is static in the scene. Would you mind coming in a call with me? Might be easier to overview the project and go over some things

[astral wave]

I am currently at work. so I cannot. I could do that in 8 hours only :DDD

Non urp render pipeline:

this setup should work. and from there to check what is the problem

another problem could be that for somereason build does not include Shaders for UI and others.

how does your build settings on graaphics looks like?

something like this?

or like this?

[astral wave]

Seems about right X.x

[jolly yoke]

just tested windows build - works flawlessly of course lol

[astral wave]

just in case what unity version u using?

[jolly yoke]

2021.3.7f1

[astral wave]

So if it works flawlesly I can imagine only three situations:

1. Continional scripting. SOmething in your project runs before camera and gives errors.
2. Build settings missuse
3. Random WebGL bug that makes no sense whats so ever................. That is more common than u could think.

[astral wave]

Build settings, player settings

[jolly yoke]

The only thing i have run on awake is to assign music and allow it to persist across scenes

only player setting that was changed was to use brotli. If I click no optimization or gzip the game gets stuck at 90%

Actually come to think of it. I might have some leftover code that was giving warnings that I forgot about. Was learning how to have sound effects persist across scenes and cut it for now (playing a sound on button click and immediately load into scene without sound cutting out)

That might be causing the problem

[astral wave]

Try check decompression fall back and run locally isntad of unity play

[jolly yoke]

Ill try running locally but ill show you the error it says about running webserver

[astral wave]

you could try to disabling game objects you think can cause anything and run as barebones as possible

[jolly yoke]

well is it possible for this to happen even if the scene isnt awake yet? the code that has these warning is on the main game , not the menu

also:

[astral wave]

press f12

go to console window

press ok

see more information about error

You have null exception somewhere it seems.

try running localy and if u get same errors. Quick suggestion to make things faster:

check these options. Run it localy via build and ruin. And you will get way more specific error. maybe even direct place of error.

[jolly yoke]

trying

just set up the dev build mode and stacktrace, building now

also removed the component that was causing errors but that only ran on gameover actually. Not sure if it would cause issues on init

Okay - so dev build appears to work !

Game is very small so I might not even care to go back and use the optimized settings if difference is nominal @astral wave

Actually wait I just zoomed out - it has one error on screen that says Nullreference , object reference not set to an instance of an object on main menu window, but the game does run

Im pretty sure its triggerloss, not sure best way to implement this aside from just having it as a separate component in the main game.
Could I write a conditional here and what would null = if nothing is found?

[astral wave]

So we found your issue. WebGL, different from other builds will completely stop on ANY ERROR. Unless it is in development build. So you need to fix your Start(function). You can try using FindOfType functions. or check is it null before using it. and if it is null, try searchiing for it again.

Also I strongly suggest dont use any of find functions if not needed. they are quite slow, and it is better not to use them too much,

[jolly yoke]

Well apparently that code functionality was deprecated and i used something more efficient - deleting the entire reference made no affects. I'll look into FindOfType - thank you for helping me learn how to debug in unity! First time 😄

I'll give the build another go in shipped mode, and with exceptions turned back off

[astral wave]

Glad to hear we somehow found the start point of problem 🙂 good luck ! dont forget: red in console = BAD 😄

[jolly yoke]

its strange that it works locally but now gets stuck at 90% on unity play with exceptions enabled however 🤔 will see the outcome after reverting default settings / shipped build

i'll have to follow up with you in the morning, 1AM here. Seems shipped still wants to refuse to run, not sure if another error will happen going back to another dev build

[flint carbon]

anyway we can use npmjs packages in unity

Im trying to use and npm js package with my wegl game is that possible

[sweet oriole]

Well you can't run them in Unity, Unity browser builds run in a regular website with all the possibilities that come with any website. Unity builds can communicate with JS on the site. https://docs.unity3d.com/2023.1/Documentation/Manual/webgl-interactingwithbrowserscripting.html

[orchid bridge]

Getting these errors:
First error is on load,
Second error is when I press my login button. Any ideas? If you need any further information please let me know and I'll provide it. Thanks.

[astral wave]

I require optimization tip. Project I work on have quite a lot of Downloading to do. All is done with webrequest download handler. Normal stuff. But while downloading the performance is really bad (as there a lot of downloads at the same time), yet CPU load difference in task manager is almost not noticable. I assume that main problem is everything is happening on one thread, so thats why it going super slow, and there is no real workaround on webgl. But it is still weirdd that non of my PC threads show that inpact. Maybe I just naive to expect to see the inpact on thread and my PC thread at the same time.

What are suggestions about that?
I thought about downloading one by one, so it would be less load at the same time, but that will take bit too long. Or download behind "loading screen". But maybe there is a secret souce>? anyone>

[fluid lily]

I'm calling some javascript code that opens a popup, and safari is blocking the popups while chrome/firefox are ok with it, any ideas?

I do the call when the user press a button in the game

[arctic rose]

Find some alternative to a popup window (assuming that's what you meant)

Adblockers can block it on any browser and Chrome + Firefox probably have some heuristics that can block it anyway. Mobile browsers don't even have the concept of popup windows.

Opening a link to a new tab should be safe

[silk brook]

why my ctrl v (paste) doesn't work on an input field on my webgl ?
while it's actually works fine on the editor ?

[mossy hamlet]

Hey guys ! is it possible to send a value from a HTML Input Field into Unity? because it's really a p... in the a... to manage the Input Field in WebGL. Sometimes it works and sometimes not.. -_-

[mossy hamlet]

Good luck with that xD it's a total scrap to have an input field working correctly in WebGL

I will start to think to use this method: https://www.youtube.com/watch?v=3g0N__K7Wlo

[bronze laurel]

Is anyone well-versed in Javascript?

I'm trying to figure out how to evaluate a button click in JS for an in-game browser event

[silk brook]

thanks let me check

[orchid bridge]

have used from unity webgl to call function in javascript, it may be other direction?

[mossy hamlet]

so it would work if the user has a HTML input field, enter his wallet address and send it into the Unity Project?

[lime mica]

is webgl production ready? how much % of desktop performance can i expect?

[sweet oriole]

CPU: 1.5x loss in WebAssembly + single thread + whatever the browser and addons decide to do
GPU: 2x loss. 10 year old graphics API.
A lot of the more clever optimization tricks may not be available due to the portable nature of the platform and old APIs, but development is ongoing both on the Unity side and web standards side (WebAssembly CPU intrinsics, WebAssembly threading, WebGPU...).

[lime mica]

10 year old graphics API is a killer

[sweet oriole]

You can still make great games despite of these things.

[lime mica]

can it handle a game like diablo 3? low poly stylized

or only ultra low poly baked lightning?

is realtime lightning not good?

[sweet oriole]

Pretty sure they managed 10 years ago with worse hardware. Whether you want to make a browser game that assumes decent hardware is another question.

[astral wave]

It all depends on your project. You will need to do things differently if you want to do it on webgl. Maybe cut into smaller scenes and etc. You can forget open world as it is. But to be honest I strongly believe something like diablo 3 is possible on WebGL, but you will need to use quite a lot of cheats. One more thing that was not mentioned, RAM usage is also not the best, some browsers can have limits how much use and etc, you you will need more loading to and out memory things.

It can handle real time lighting, but I strongly suggest against that. Baking lights is almost a must, but you need to do it cleverly as of memory limitations.

URP
Addressables
MemoryProfiler
Profiler
Unity 2022

This things is what you are looking at and is quite a must.

[astral wave]

https://docs.unity3d.com/2022.2/Documentation/Manual/webgl-interactingwithbrowserscripting.html

You can easily send data between JS, HTML and C# with these. dont forget you will need to transform stringToUTF8 and everything will be smooth.

[mossy hamlet]

Thanks ! We will try that. Do you know well the Input System ?

[astral wave]

I am using input system in my project. So I know basics. You can just download 3rd or first person controller and study example provided by unity.
https://assetstore.unity.com/packages/essentials/starter-assets-third-person-character-controller-196526

[mossy hamlet]

I already use it but I have some issue between Desktop/mouse Vs Mobile. Is it possible to write you a DM to see if you can help me for that?

[astral wave]

sure. I cant promise to be very helpfull, but basic questions I can answer

[mossy hamlet]

great, thanks!

[cloud ermine]

guys how to configure Unity 2020 Web GL memory allocation ?

my current build is totally out of memory allocation

https://github.com/Bunny83/UnityWebExamples/blob/master/ExpressionParserWebGL/Build/ExpressionParserWebGL.json#L7

is this working ?

[astral wave]

update to Unity 2022 for extra goodies that could maybe replace your needs

[cloud ermine]

seems this config only shows up for 2022,
I didn't see that on 2021 tho ..

[astral wave]

yes it is only on 2022. WebGL got a bit love on 2022. and most of features will not go to lower versions

[cloud ermine]

wish my multiplayer framework allowed this version 🤞

[cloud ermine]

what makes difference between initial & maximum ?

do I need to set max the initial memory size ?

[cloud ermine]

what specific version of 2022 ?

[unborn marsh]

Hi I'm getting
abort("both async and sync fetching of the wasm failed") at Error at jsStackTrace
Does anyone know how to fix this? Thanks!

It worked earlier and now just stopped

[unborn marsh]

When I choose GZip compressing it doesn't show any errors but also doesn't load (Just Unity image and empty loading bar)

[strange tangle]

Has anyone had any trouble building with 2022.2.0b6? I keep getting the build process frozen at linking wasm files 😭

[astral wave]

2012.1.12 or later. otherwise you wont be able to connect profiler to your WebGL project. Well if I understand correctly, some meory is assigned at the start, and if it snot enought it will expand until maximum. when reach maximum you will get memory out of bound message. But for WebGL youshouldnt aim more than 512 MB anyways so

[astral wave]

are you testing localy or remotely?

[unborn marsh]

Locally

[astral wave]

build and run? or local web server? As if local webserver have in mind that index html differs depending on which mode u using

[unborn marsh]

When I'm doing build and run, it's giving me the error above. When I'm using local web server (react-unity), the game is working great except when I click a specific button and it gives me the error above

[astral wave]

have you tried this?

[astral wave]

So even with gzip it works until you click specific button?

[unborn marsh]

When I use gzip it just stays on empty load screen (build and run because unity-react requires no compression method so I can't upload .gz files)

[unborn marsh]

Yep tried on and off with everything

[astral wave]

hmmmm, I have not problems with brotli tho on that end... hmmm

[unborn marsh]

Yep it's strange... It started happening even with a build back from 14 of July... Now I have the same problems with this one

But a new build from a new project works

[astral wave]

what is your unity version?

well if new project works. maybe your library got corrupted

you can try deleting library folder in your project and let it rebuild it self on next start of project

if there is really no other key elements you added, like updates, new scripts or plugins

[unborn marsh]

2020.3.14f1

[unborn marsh]

No I've added A LOT of scripts since 14th July... But depleting library folder sounds reasonable, I'll try it. May this be a windows problem? Because when I run js files from build folder manually it's giving me Windows script host 800A03F2 error

[astral wave]

maybe setup of your webserver got access problems or something

[unborn marsh]

I just found out that it does work when I'm using build and run. But when I run index.html from the build folder, it doesn't load

[astral wave]

Running index.html have a lot of limitations.

1. browser security. you need to disable security of loading webgl applications. each browser have different setup

2. I dont think that it will work unless you put it in your local webserver. What ever app you using IIS or etc. But then webserver needs to be configurated to run compressed data

3. make clean build. if you not making clean build there is a chance you still using old indexhtml, which have wrong files setup to load. Or before building delete everyfile in that folder

[cloud ermine]

how do I know that since 2020 doesn't have memory profiler yet

can't move on from 2020 at the moment since one of my plugin was made there

[astral wave]

https://docs.unity3d.com/Packages/com.unity.memoryprofiler@1.0/manual/index.html
You have memory profiler on 2020. just install it from package manager. You might need to allow preview packages.

[cloud ermine]

I've been seeking it hours ago on registry but can't find it, let me double check

[cloud ermine]

but still can't find a way how to maximize my webgl memory on 2020 T_T

on certain scene it keep saying memory out of allocation

[cloud ermine]

I mean I already have everything here, but yeah on 2020,
I really no idea how to put a maximum allocating memory on webgl

[jade valve]

i uploaded a zipped webgl build to my unity dashboard. when i try to play it from 'build history' i get 'unauthorized'. any ideas why?

[cloud ermine]

wdym ?
is that a webgl project ?
we used to do open project manually

[faint grove]

Has anyone seen this OpenGL ES exception before when pressing the browser back button to exit a Unity WebGL page?

exception thrown: TypeError: Cannot read properties of null (reading 'deleteFramebuffer')

Also, are the loader.js and framework.js files that Unity creates for WebGL builds available anywhere in a more human readable format (i.e. with new lines, spacing, etc)? I'm assuming that it's inlined to save space but it would be amazing to see a prettified version.

[orchid bridge]

My webgl game isn't loading when I use my auth. I had a thread but apparently my issue wasn't important enough to staff 🤦‍♂️ .

Auth works 100% with windows (mono and il2cpp) but when it comes to webgl it isn't initializing my auth.

[cloud ermine]

are you with firebase ?

what Unity version ?

[orchid bridge]

No, different Auth called KeyAuth. & one version before latest update.

[cloud ermine]

which verrsion of Unity ?

[sweet oriole]

Did you make a forum thread? Unity is more focused on providing support on the forums than on Discord.

WebAssembly or at least Unity's C# implementation on it appears to be very network restricted, so if you aren't using Unity provided network methods, you should probably doing it through JS.

[plush oxide]

Please is there any leaderboard plugin that works well for webgl builds?

[orchid bridge]

Yes, I got a response from Unity Tech but they couldn't help... they provided information that I already tried... I made another thread and a random user responded and again... only provided information/suggestions that I've already tried.

[orchid bridge]

I'm using WebClient (System.Net)... I figured it had to be something wrong with the request but just couldn't figure out why WebClient wouldn't work on webgl 🤔 ... my auth just doesn't want to initialize and of course that init code is the the one that's making the request... I tried RestClient as well and still nothing.

[cloud ermine]

there is, but at an rpg framework

[plush oxide]

Thanks, but Wdym by rpg framework?

[cloud ermine]

this is webgl build room ...
try to drop the question on general

[patent beacon]

been half an hour, still not done

this is taking so insanely long

wait just done

lmao finished right now

btw do I have to set the itch.io project to 'html' or 'unity3d < 5.1'

alr I set it to html and it works

but it doesn't set the screen size for me

[cobalt finch]

anyone familiar with firebase webgl? Im getting a firebase.firestore is not a function error

[cloud ermine]

what service you use ?

[cloud ermine]

yeah it's extremely long true
the amount of your files definitely take part of the building time length
particles, effects, etc

[cobalt finch]

oops, i resolved the issue. Apparently I was using the "import" method of importing the module, but the accepted one is to use the <script> tag in the html file

[astral wave]

Depending on pipeline. Everything in URP works. Nothing too much to be aware off of what I can remember. If you using addressables prepare to create your own shader stripping or Unity will add all shaders variants in your project and destroy the memory usage.

Still webgl is very performance heavy, so the simplier shaders are the better it is.

[astral wave]

Oh also depends on your Unity version there were some bugs regarding shadows on shaders, and they might be invisible if recieve shadows is used. but it was fixed so if you are using newest version, there should be any problems. Also I suggest using 2022.1.12+ version, as 2022 have more things on webgl than previosu versions and quite a lot of things wont be backproted to older versions. have fun in Hell that is called WebGL

[flint carbon]

unity webgl build gets white screen while playing with this message - WebGL: CONTEXT_LOST_WEBGL: loseContext: context lost

is anyone familiar with what this is

[astral wave]

This one does not ring any bells, are there any more logs on browser console? If not you can try building developer build with full stacktrace to see for more logs

from what I see on forums, it is when your browser loses control on your GPU. Try reducing resolution and improving performance and test if that still happens

Also check if you not running out of RAM while loading somekind of model

some people reported that changing renderer size helps

So in short, most likely Memory leak of some kind until you crash your webgl

[cobalt finch]

For firestore in webgl, how do i pass in merge options for SetDocument?

Basically I want to use IncrementFieldValue, but I want it to automatically initialise the field value if it does not already exist int the database

[patent beacon]

well it only ended up with 11 mb of files after building

no particles or effects

3 animations

so that was sad

as least it worked

[flint carbon]

yeah ive checked im loading api which downloads more than 500 from servers and shows them rawimage thing when this is happening i noticed that the ram exceeds more than 11gb

i think that might be a reason right for the game to crash

[flint carbon]

for this the game is being completely run on cpu so i dont think its using dedicated gpu at all

anyway i can reduce the load on cpu when donwloading those images

[flint carbon]

ill just run once again see other logs as well

[flint carbon]

im also getting this one - [Violation] 'load' handler took 928ms

[flint carbon]

also anyone know how to stop this from happening

SocketWebTcp.Disconnect()

it happens on its own

[novel cipher]

is this because unity can handle null pointers but as default webgl builds do not?

[astral wave]

By default webgl crashes on ANY errror. You can evade that by enabling debug build. And I suggest to add fulll stact trace and then on crash check logs so you could see exact line of code that makes it

[astral wave]

Downloading images from web and displaying it uses HUGE amount of ram. For example 1mb image will take about 12mb of ram.so you can imagine how fast it blows up. I havent found the solution to this yet. Most likely need somehow compress on load, but still not sure how to do that.

well TPC conncetion timeout can be increased on your webserver.

'load' handler took 928ms this one ... well you can ignore that. at least I do. it is more about webgl is beeing too big for browser. but it will work anyways

https://assetstore.unity.com/packages/tools/integration/webxr-exporter-109152

What is difference between this and your project?

oh it is exactly that 😄 lolz

[novel cipher]

it seems to be very hard to get the webgl to render correctly

i have no idea why it is drawing something weird on bottom of the screen. i mean that reddish / orange thing that should not be there

[astral wave]

Oh i thought that is just HTML 😄

As red arrow shows at the text, which is set to be bottom right. So I would assume the Actual screen of webgl is The blue line screeen. and under it is index.html template default webgl logo with full screen button. As that button most likely is HTML, at least from templates I have seen. So thats why i tihnk the redish part is also part of html. But that is just my guess

[flint carbon]

yeah will try this

[flint carbon]

yeah for tcp connection that happens on local builds as well so any way i can increase the timeout

[astral wave]

network manager, but it sohuld be big enough

sweeeet. I hope you will have more luck than me. Expeccially with all limitations on it 😄

Oh that was two years ago. Now I can't even remember what problems I had with VR. Besides not beeing able to use XR unity plugins normaly, and eveyrthing needed to be coded from scratch. Performance issues when it comes to any more complicated scenes. Problems with making it Full screen without plroblems on different browsers. HTTPS permissions issues.

but that was two years ago, so maybe some things got better.

And the worst... 60 fps limitation on browsers......

[flint carbon]

I'm not really familiar with what this is canyou please tell me how to change that

[astral wave]

ohhhhhh wait a second.... what network solution you are using? Websockets ? Mirror? Photon?

[flint carbon]

photon

[astral wave]

my apologies, I do not have screenshot where to edit it there

[flint carbon]

ohh any idea where i can find that to change the settings

photonmanager.keepaliveinbackgroud will this work

[astral wave]

well that is kinda a must. as if window is not active you wil lget disconnected

but from what i learned with mirror, that wont really hellp on webgl if you will have other window opened

[flint carbon]

oohhh

i cannot find the code where i can increase the timeout

increasing the timeout will that be sufficient ..??

[astral wave]

Tbh no idea. YOu shouldnt get timeout in the first place as long there is no errors. Well sometimes there is problem with web server. As Photon time out is longer than WebServer timeout. So webserver time outes and closes websocket early.

that option depends on your webserver provider

[flint carbon]

yeah thanks will look into the problem if i can find any solution to this. Thansk

[warm quartz]

wanna ask how to deploy your dedicated server and webgl to host and client with mirror any tips?

I just realised here has a webgl channel

and I know I need ssh what requirements do I still need to make it host and client?

[astral wave]

https://mirror-networking.gitbook.io/docs/transports/websockets-transport

Here you go.

[warm quartz]

need to install any software in my win or Linux?

[astral wave]

you want to host it locally?

[warm quartz]

I wanna host it like first client join

does it possible with dedicated?

abit like create lobby than called the host

like server room

something like this in a dedicated server

[astral wave]

https://www.mamp.info/en/windows/
https://www.apachefriends.org/
windows IIS.

This can help you make local host.

IMPORTANT: WEBGL CANNOT HOST with mirror. you can only connect as client. You will need linux or windows host.

To test as client you can build serverr run it. And then just press Build And RUN in unity on webgl platform it will automaticly will host your webgl and u can test it.

[warm quartz]

I already have Linux and Windows host

[astral wave]

Yes, you can build room logic with one, or multiple server with mirror. it is not out of box but you can.

[warm quartz]

but the things was I do no how does window or Linux host work

when to create when to close

so it borther me weather need to install software behind

[astral wave]

if you will host on your computer, you dont need any applications.

1. YOu need server buiild.
2. then open ports used for your server (otherwise noone can connect outside the connection). Locally everything will work.

[warm quartz]

but if like that wasn't i only able to connect into 1 room?

cause I am thinking about can I like https something / 1 2 3

is just like creating a room with parameters

cause seen my client cannot be https or http instead of my dedicated can be https from ssh

and my client need to local to my decidated wasn't it?

[astral wave]

You can connect with webgl only on same domain. Mirror by default dont let you add parameters, only main html/ipaddress. You will most likely need JS which will read you Path parameter, pass it to WebGL, which will change PORT number to correct Server or Room. Depending how many server and rooms you will have.

then you will connect to server and there all depends on you.

[warm quartz]

so as default it all depends how many server I create in my Linux and win is it?

is like that so ah F this gonna be hard

@astral wave can I add you and forward me the details?

[warm quartz]

I mean this

oh we already friend

😂

[astral wave]

yes, webgl is pain in the ass and I suggest everyone not to use it if they can 😄

[warm quartz]

I need to use it to develop mobile stuffs

😅

[astral wave]

well depends on your game scale. you can have one server with 100 rooms of 3 or 2 players. or you can have 100 servers with 100 rooms of 200 players.

[astral wave]

anyoone who wants develop webgl on mobile have a lose screw. Just make an aplication.

[warm quartz]

the things was this will add into build application

that's the things

😅

[astral wave]

ufff

[novel cipher]

yeah i am starting to feel this way too... at first i thought that with unity you can easily build for all platforms, but it is not so simple, well, you can build, but it is another question how it actually behaves and works

[novel cipher]

i was thinking about switching back to using older versions of unity, as i think they are faster and lighter to use. but do they have even more issues with webgl builds? or has it been getting better with new unity versions?

[novel cipher]

thanks, i was kind of afraid that this is the case

though i think my shadows are working

[warm quartz]

Good topic I wish I can done this tasks

[faint grove]

Is it possible to modify the framework.js file that Unity auto-generates for webgl builds? Like pre-build, so I don't have to manually modify it after the build?

[faint grove]

I want to modify the _glDeleteFramebuffers method in framework.js. I need to put together a minimal project for reproduction purposes that I can use to file a bug with Unity, but I haven't gotten to it yet. In the meantime, I need to add an additional null check in that method, as it's throwing an error for us when a user exits our page.

[faint grove]

I'm probably just going to do this with a PostProcessBuild method, although if Unity changes the contents of framework.js in future versions, that will of course break. Ah well, at least it will work for now.

[astral wave]

Was that a sarcasm?

1. you still downloading it, so size is still the same, it is just stored in your browser cache. Where cache control is a mess. You can download game and made it run without installation. On phones, just download app from asset store, have icon always ready on you menu, without opening any browsers, best shortcut ever. The URL convenient only if you use the application ONCE. As if you would use it more often, it is actually less convenient. If you make WebApp to be used only once, sure it is way better than downgliding. Thats why I think WebGL is amazing from presentations, more live 3D model preview. But game? ..... Well.... questionable. As almost all games are made for people to play it multiple times, or over multiple sessions. Even monetizing is better when user joins application everyday, so they will have more chances to buy things.
2. Or your target people are one who plays video games in work, where they cant install anything.
3. and what you get as exchange for this questionable advantage of using WEbGL? :
   a) no need to setup application store of any sort on mobile.
   b) no way of prove security rather than saying it is secure for client
   c) losing tons of performance, beeing forced of limiting user experience, visual fidelity, increasing time needed for development by at least 3 times
   (build time alone ignoring all bugs that comes from webgl).
4. you learn how to use profiler and optimize your game pretty well. yet you hate your self everymoment as it still dont run as well as you would like it to run.

dont get me wrong, there are situations where webgl can be super. for example events. where people will use your webgl and wont use it again until next event or at all. when target people are dynamic and quite random.

[sweet oriole]

Yea there is a team constantly working on it. 2022 saw an emscripten upgrade and a WebGL extension to support SRP batching. AFAIK supporting and validating mobile has been a major focus recently, so you might see some improvements there.

[balmy thicket]

Hey folks, is it possible to publish to Unity Play privately? I'd like to use it as a convenient server alternative for sharing dev builds with my team remotely.

[high patrol]

yeah Unity has a hosting solution for that I believe with Cloud build

$$$

[flint carbon]

I previously had a discussion about Web socket disconnect in this chat. I couldn't find a possible to way the disconnect from happening. I'm using photon. I was thinking to add a reconnect to the web socket with playerTTl. Will that be any possible fix to this problem..??

[indigo crest]

Hey, i have a VPS server with mysql database and some php files to manage the data. The game works fine hosted on the same server, but when I try to upload it to itch.io, i get this error : Access to fetch at URL 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.

[indigo crest]

That's very helpful, thanks you so much. Not only you help me with my issue, you explain how it works, couldn't be more grateful. I'll test it out in a few hours and let you know.

[indigo crest]

It worked, thank you very much, hope more people would be like you.

[flint carbon]

im using sendmessage in webgl index file and doesnt seem to work

ive put this is code in script tag in last part of the body tags

[visual hemlock]

So, I know next to nothing about Unity so after countless days of searching and testing things myself I've decided to come here. How on earth do I open up a .unityweb file in Unity?? I know it is possible as I've seen an acquaintance do this, but he won't share how he has done it for some petty reason which isn't really relevant. At the moment I'd just like to get into the project.data.unityweb file, which I've already done using AssetStudio. If it is possible, which I don't know if it is, getting into the wasmcode.unityweb, wasmframework.unityweb and alike would be a big help too. Please ping on reply if possible, thanks :)

[arctic rose]

You can't open the file directly in Unity. You'd need to decompile and rip the assets first which is off-topic here.

[visual hemlock]

I think I've figured how to decompile and rip the assets already, but which would be the appropriate channel for talking about that/asking questions about it here? Also to clarify, the person who has supposedly opened the file directly in Unity, is he just bullshitting that or has gone a different route?

[somber oxide]

everytime i click refresh on edit thingy it just says failed

why?

[arctic rose]

It's not appropriate anywhere in this server.

[visual hemlock]

Ah, gotcha.

[somber oxide]

im trying to download editor and it just says failed

if i refresh it

after like 2 seconds

it fails again

help

How do i solve the issue of hosting my webgl application on a site, and Chrome browser blocks my UnityWebRequests to fetch data from other domains due to CORS?

well, lets say i am the one hosting on wordpress called mysite.com, and i am making the request to lets say, examplesite.com

so should the header be applied on my site's php file or examplesite's php file

mysite.com, and i am making a request to examplesite.com to fetch a png from their site

ok wait

aw

the issue now is i dont have control other domains, and i am trying to fetch data from their site

what does this mean

any idea where to start? prefably the easiest solution if possible

😮

correct me if i am wrong, but it is because Chrome browser itself have cors as a security

because i ran chrome with security disabled and it runs fine

yeap

so its not wordpress thats blocking it, its chrome

because i set the php header in my wordpress file already

and the htaccess file

and its still not allowing, so yea its chrome

which im not sure how to solve

alright i shall try to decipher this xD, still an amateur on custom endpoints and stuff

just to clarify, this cannot be done via Unity only? Do i need to setup some extra server or something?

[tough cypress]

i cant interact with the UI of my webgl build when its not fullscreen

im using version 2020.3.12f1

webgl having this issues with s3

[ashen lark]

Hello. I'm making a custom web Template with VueJS, and the unity-webgl package, which allows me to get the specific files. However, I'm also following a build-name scheme. Is there a way to pass the build name as a variable to the template?

[orchid bridge]

Hi There,
would anyone be able to help me out with this issue. im trying to publish my finished product onto my profile but the builds running into errors i just am not familiar with
what does this mean

[cloud ermine]

how does it look ?

like kongergate webgl ?

[ashen lark]

No? It was custom made by me. But I didn't make use of the {{{ variables }}}

[astral wave]

so when webgl 3.0 is comming? 😄

[warm quartz]

EXCEPTION: SocketException Message: No connection could be made because the target machine actively refused it.

https://www.smartftp.com/en-us/support/kb/58

I checked the article I wonder is it because of firewall or port build

cause I am getting an ip address and port from my dedicated server

[urban storm]

hey guys, I am quite new to unity world, and I'm trying to make a webGL Unity hosted by React, but it is not working for me.

this is my code

this is the situation

Nevermind, It was compression issue!

[cobalt finch]

hi, I am aware that window.onunload event does not gurantee that all subsequent callbacks will complete fully. Any way to tackle this? I am using the unityinstance to sendmessage to call a function that logs data (which calls their respective callbacks), and my data logging callbacks does not run when the page refreshes

[zenith mason]

Hi guys. im trying to take a snapshot in memory profiler from webgl build. When I have focus on the application in a browser the console logs that the profiler is connected. But when I hit "Capture snapshot" it logs that the application was paused.... How can I do that?

[tardy musk]

I have a problem with the LoginWithCustomId() function. I'm making a game which i published on web and windows for now, I am using SystemInfo.deviceUniqueIdentifier as a customid login. However, this doesnt work on webgl, since its not supported there, does anyone know a solution to this problem?

[arctic rose]

There are no device ids available on the web. You can generate your own and store it in playerprefs for example.

[tardy musk]

Do u have a suggestion on how I can create them?

[arctic rose]

Any way you want, for example Random.Range(100000000, 1000000000)

[tardy musk]

Ok, but then it is technically possible that it’ll be the same for another player

[arctic rose]

It's technically possible for device ids to be the same as well

If you're worried about collisions, make the random id longer

[tardy musk]

Is there a way to check if they are the same?

[tardy musk]

That’s what I mean

[arctic rose]

No, obviously not

[tardy musk]

? Ofc there’s a way

[arctic rose]

I'd be keen to hear it

Well, if you store all generated ids to a database and compare to them when you generate a new one, then maybe

but why bother

[tardy musk]

Hmm

Ok thx for helping

[arctic rose]

For example, if you generate a 64-bit id and everyone on the planet plays the game on a new device every day, the first collision is expected to happen in a few billion years

[high patrol]

you could do Time.time down to the milisecond + a random number + a random salt + run it through a hash algorithm like sha256

if you're paranoid about collisions

[sweet oriole]

You probably want to use existing GUID generation mechanisms over gobbling something together in the hopes of not getting a lot of collisions. On the other hand, if you are trusting the client to do something reliably, you are going to have a bad time.

[wet fog]

hi, trying to play a music in webgl from url, is this possible?

so I was trying to use something like this to get files from url. It works great in editor but in build I get a "ConnectionError" from this debug

[wet fog]

okay :). preferred is mp3 mpeg, but might be wav, thought its not easy to convert from byte[] to audio?

[wet fog]

okay, I only have issues with downloading it

tried this and this and nothing realy works

[languid sparrow]

srjagh,erglqerge 'error creating webGL context'

~unity 2022

it runs on a page generated with build but not when i embed it on a page that uses canvas made by me

[wet fog]

hm, how would you go about downloading an audio from url?

[languid sparrow]

No clue, what does the result say?

[wet fog]

it says 'ConnectionError' :/

[wet fog]

okay I found the true cause of this :D, trying to figure out the solution now

[wet fog]

okay found a solution nvm

[urban storm]

Hey guys, one question here:
If I make a WebGL game and publish them via webview on mobile app, does that game run on local devices or I need to provide a server that runs it and pay for that?

[patent pollen]

games always run locally until you tell them to communicate with a server, so unless you need some type of multiplayer capability, you will not have to pay for a server

if you want to put it on a website tho, you will need to pay to host the website and pay for the domain

you can host a webgl game on itch.io for free, so if money's an issue and you're ok with hosting on a third party website, i'd highly recommend checking it out

[urban storm]

Thank you sensei!

[lost oak]

Hi friends, very new here and been playing with unity a few months now 🙂

I’m developing a mission based web game (2d battler) and could get up to 100+ different missions that are selectable from my web page (and not within unity).

Question: Would it be better to create a different webgl build for each mission OR should i create multiple scene within one webgl build and use

my webpage to determine scene to load?

[tardy musk]

how do i check in c# if the project is running on webgl?

[sweet oriole]

Runtime: https://docs.unity3d.com/2023.1/Documentation/ScriptReference/Application-platform.html
Compile time: https://docs.unity3d.com/2023.1/Documentation/Manual/PlatformDependentCompilation.html

[lost oak]

Thanks allright! I will start down that path with one build. I’m guessing I should prefab as much as possible to keep the file size to a minimum and try re-use prefabs in each mission scene?

[astral wave]

Prefab and start learning addressables package 🙂 laoding and unloading assets from memory.

[astral wave]

Also addressables will be perfect for you. Not only you can select stages which to load and unload. One webgl build will save tons of download when you use addressables smartly. For example create package which are used in all your levels, it can be UI, or some other models, like character models and etc. And this way it will download only once, and after that you can load it from cache, so extra stages download and load time will be shorter. Good luck with WebGL, you will need it 😄

[orchid bridge]

Why can't I build for WebGL?
"In order to build a player, go to 'Player Settings...' to resolve the incompatibility between the Color Space and the current settings."
What is this?

I went to Player Settings, but I can't find any such option

I must've missed something?

[vapid zenith]

It's under "other settings"

[orchid bridge]

Ah, OK, ty, I found it

It told me to uncheck "Auto Graphics API"; not sure what is that, but regardless, unchecking it got rid of the error message

Does WebGL compute physics differently from a PC build?

my balls are bouncing off significantly differently in WebGL and in the editor

[astral wave]

Answer is yes and no. Physics is the same, most likely differences you have is because of frame rate you having. Try locking frame rate to 30 on both platforms and it should bounce the same.

[astral wave]

you will want to use webgl 2.0 there

[haughty stump]

Hi does anyone know why I can't build WebGL

@woven sail

[astral wave]

Open you UnityHub and check if your license is there. If it is there, remove it and add new one. I assuming you are using personal license.

[haughty stump]

Yeah. i only have a free version of personal license~

[astral wave]

try re-adding it again then. logout and login again anc try again.

[haughty stump]

Return license?

[astral wave]

yes. as it is personal license you can do this as many times as you want.

[haughty stump]

I am curious whether the browser version supports the most features which compare with PC version?

I knew some features do not support HTML5!!!

[astral wave]

talking about licensing? account managing? or WebGL builds?

[haughty stump]

No, that was a topic about the game platform support to some game content features.!!

Not mentioned the first build issue on WEBGL🥳

[astral wave]

There are quite a lot of things WebGL dont support. VFX graphs is one of examples, HDRP is another one. It only supports webscokets for networking. and etc.

multithreading is pretty much dead. Mostly you wont able to use most of it. You can still use tasks, but it will work on main thread so same as coroutines and not controls over that

[haughty stump]

Do those features not supported caused of security reasons or not implemented yet?

[astral wave]

VFX graphs is due webgl is super old, and it is missing core features of it. HDRP is not implemented and I think will never be, as performance hit is just too big. Multihreading should be implemented in the future, but that is decades away from what I see :D:DDD

there are a lot of stuff that are blocked "for security reasons". Like loading content only from your domain and etc.

[haughty stump]

I am so excited to expect the browser platform can support the games such as Riot games, is it possible? how long is it possible?🤔

[astral wave]

There are multiple clones of Moba on webgl already. So it is totally possible. However I cannot understand excitement. Only hyper casual games will prevail on webgl, as otherwise you sacrifice too much. Max 60fps, performance loss of 4x times and more, network limitations, troubleshooting problems and etc.

[haughty stump]

Aha, casual games like feeding livestock, planting fruits, and operating a farm in the WebGL. It is specifically for those people who are working in the office.🌻

[winter stone]

Hey all 🙂 Im trying to debug a weird issue: I have a canvas with a raw image in a scene. Attached is a script which is creating a render texture and tex2D at runtime, assigning it to the raw image, and then just assigning random colors using Texture2D.SetPixels, Texture2D.Apply and Graphics.CopyTexture in a fairly normal fashion.

In editor, this is working, however as soon as I build it out, the texture disappears. Not white, black or pink, absolutely not visible. No errors in console, and if I debug, the data is getting created and updated properly, i just cant see it.

Test code im using here: https://gist.github.com/DraconInteractive/9b51eaee76d2577636d7975cce3e35f6

Any advice very welcome, been on this one for a bit

[astral wave]

My guess would be nothing wrong with code, but more with material you are using for rawImage. most likely the shader is not added or by default it selects unsupported type. To test it you can build it with static picture added manually with same material or without it and check what will happen.\

[winter stone]

apologies, i meant to post back here! I found out that webgl doesnt support copytexture for my version of unity (2020.3), so i changed to passing the texture to a sprite shader, which is working great 🙂

[orchid bridge]

I am sorry, but discrepancies occur regardless of frame rate 😦

This is behavior in editor and on PC builds: https://www.youtube.com/watch?v=psV55tB-ThY

This is behavior on WebGL: https://play.unity.com/mg/other/webgl-ojn

Limiting framerate to different values does not seem to affect the outcome ;/

Given that discrepancies only start to become significant after a few bounces I'd guess that WebGL and PC must do floating point computations a little bit differently? So tiny errors accumulate and finally result in wildly different outcomes

[astral wave]

Hmmmmm. Physics calculations is way slower on WebGL, maybe thats the reason? Also I watched the video and game multiple times, it seems biggest change when both moving objects hits each other.
What is your rigid body Interpolate and collision detection modes?

[orchid bridge]

Interpolate is None, Collision Detection is Discrete. These were the defaults and I didn't change them

Also, to my intuition slower calculations should make the game lag, but not change game mechanics?

[astral wave]

try changing Collision detection mode. It might change how it works. Well because physics calculations works on frames, so it is calculated every frame, but if you have lets say bit of frame drop, so you miss one frame, and in that frame collision appear, the base values of effect will be bit different then. or something like that. I am not physics expert tho

[orchid bridge]

I changed the collision detection mode to Continuous (to my understanding this is the most accurate, but also most expensive mode) and the results are still the same. I then set Application.targetFrameRate to 15 (just to be very sure), but this still didn't change anything.

[analog burrow]

Hi, what is the proper architecture and library for making and deploying WebGL multiplayer game

I'm learning PUN now and they said PUN doesnt really support WebGL socket well, they recommended using their server Photon Cloud

I also read somewhere and they said I should make a server using node.js, but i dont really know sure how to combine that with PUN and how to override PUN socket

anyone have experience in this?

[astral wave]

You might be correct then. I am not suprised that on WebGL it is bit different tho. Maybe use curvers instead to fake physics... offcourse that is way too much work, but visuals will be similar

[orchid bridge]

This is surprising to me tbh, since some games are very reliant on physics. It wouldn't be fair if the core mechanics of a multiplayer game were different depending on whether a player uses a PC build or plays in a browser!
I am trying to complete Unity Learn tutorials, in this case I am stuck on this one: https://learn.unity.com/tutorial/challenge-the-floor-is-lava
Completing it requires that I publish a WebGL build of this exercise https://learn.unity.com/tutorial/publish-your-project
I am annoyed since I spent many hours polishing this in Unity Editor just to see that WebGL behaves nothing like what I see in the editor!
...sigh...

[astral wave]

well.... you will meet this feeling multiple times while working with webgl.

I found something about it. you were correct. it is precision difference on webgl. uff....

1) This is a precision issue that we can't easily fix for WebGL/JS. Sorry.

2) You can workaround this by changing the Fixed Timestep physics settings.

or

 workaround is placing a box collider for the rigidbody to collide with first, because then subsequent collisions with mesh colliders work.

[astral wave]

https://doc.photonengine.com/en-us/server/v4/operations/websockets-ssl-setup
Nothing more just this. You are forced to use websockets as your transport layers. everything else should be the same as any other Photon stuff

[analog burrow]

thanks for your response, I will take a look at it

[orchid bridge]

Oops, changing Fixed Timestamp makes the balls bounce wildly differently even in Unity Editor...

But, many thanks for your time and efforts to help me with this 🙂

I'll try the box collider workaround and if this still doesn't work, I think I'm going to give up ;/

(although I'm not really sure how to place a box collider for the rigidbody to collide with first, i don't want it to bounce off the box collider, it must bounce off the mesh collider... there should be a way to make it collide with but fall through the box collider, I'll try to experiment a bit)

[visual siren]

On unity 2022.1.16f The directional light seems to not work when scenes are additively loaded. Is there a fix for this ?

How to merge post api in unity? with MSSQL and C# code

[tardy musk]

I have a problem, im making a game thats currently on webgl, i want to show touch controls only when the player is playing on mobile, but not when the player is on pc or something else. How can i do this?

[ember flower]

am I the only person getting mouse locking issues in 2022.1.17f1 in WebGL? the mouse is hidden but seems to be moving still and when it reaches one side of the screen it jumps to the other side and moves the camera with it

[sweet oriole]

File IO API is functional in WebGL builds, so you don't necessarily have to change much.

[orchid bridge]

Does brotli compression not work with WebGL on itch.io?
I get errors when I have it enabled

[sweet oriole]

Your hosting setup needs to properly handle sending files with the correct HTTP headers https://docs.unity3d.com/Manual/webgl-deploying.html, though this can be a bit more to figure out with thirdparty hosts.
Important projects should figure this stuff out since you lose some % of users for each MB they have to wait for a download.

[oblique canopy]

Hi guys, any guide to deploy gzip build in Ubuntu nginx? I followed docs in unity but still need some fixes.
https://hastepaste.com/view/jYQO5
Here is my config and bug report.

[high patrol]

I've only hosted with node

[full star]

I published my game with WebGL to try it out(its a work in progress) but when I press play in the Unity Play window the scene loads but my player is not visible. Any idea why that could be? If I press nothing it stops automatically and asks if I want to save it for a thumbnail. However if I press the movement buttons it does not stop until I stop it, so the character controller at least loads. But I can't see the character.

[hardy panther]

I've seen several 3d first person webgl games encounter the same problem when being run on firefox -- the camera, which the rotation is tied directly to the horizontal mouse input axis, constantly drifts to the right by a fixed amount

It's not present when I build and run my games -- only when they're being hosted by sites such as itch.io

there's no player input during the first 5 or so seconds of this clip

just as I suspected

[hardy panther]

on another note, I've discovered that webgl doesn't support urp decals.

[novel cipher]

does it work without that bug with other browsers?

[lime cradle]

Does mobile browser WebGL support Input.deviceOrientation?

[hardy panther]

yeah

[halcyon pier]

I'm hoping some one can help ! My mouse look is totally broken on WebGL! when you move the mouse on the X to look to the sides when the mouse hits the edge of the browser it stops. So basically I cant turn around in the room all the way, its clamped
even in full screen it does this

[halcyon pier]

turns out it messes up because i brought up a canvas , enabled mouse and unlocked cursor and then when i relock it all it messes up

[sterile oracle]

Hi there a have errors to webgl

Why does it give an error?

🤔

Hello?

[sterile oracle]

this is what Unable to parse Build/Build.framework.js.gz!?

[sweet oriole]

The error message is probably quite accurate. You can ignore all of this by disabling compression or using compression fallback.

[craggy verge]

i'm looking for someone to help with a webgl project (just for previewing materials on a sphere). i gave it a go but i'm having trouble with the production build and the tessellation/displacement shader. if there's someone who is interested in working on it or giving me a hand 1-on-1 i'm willing to pay for your time

[sterile oracle]

i get fixd!

[halcyon pier]

if you have issues complaining about GZ lib missing or whatever and turning compression fixed it , another way to fix it is install GZ support on the server

in other words unity uses gzip to compress things but it assumes your server has that installed

[lofty osprey]

Anyone knows why URP Directional Light cookie renders on Chrome/Edge, but doesn't render on Firefox? Unity 2021.3.11f1, URP 12.1.7

[astral wave]

WebGL magic ;D The pain we need to handle. This playing with shadows settings, it is quite often that disabling shadows on shader helps with rendering. Anyways I strongly suggest go to 2022.1 for webgl builds, as it have quite a lot of fixes whihc is not going to be backported.

I have question as well. So I build scene on webgl with Terrain. Stripped not nessasary shaders. And what I got quite interesting.

1. PC -> no problems
2. Android 8 -> no problems
3. Android 12 -> Terrain shader is invisible. Bushes are visible, but not terrain it self.
   Unity 2022.1.16
   Anyone had seen similar problem or have any tips.

[tawny cargo]

my game works when i press play, but when I try to publish to WebGL the camera isnt centered, some text that should disappear during the game managers start fxn is still there, and no buttons work

first: the camera thing. My game only looks right when I'm in default layout. What do I need to do to set that size as the right size for all games?

and second: any thoughts as to why the webgl build is off?

[high patrol]

check your build resolution. Check your camera resolution in editor. Make sure they're the same

[tawny cargo]

OK I've figured out all issues with the layout in webgl. but when I press the play button, it just becomes disabled. the game still doesnt play out or do anything (as it would if I just pressed the play button in the editor)

if this is noteworthy my game does a webcall when i press the play button. no issues though it works fine

[dreamy pagoda]

anyone got any ideas on this issue?

works fine as a desktop build

after looking a little into webGL debugging here https://docs.unity3d.com/Manual/webgl-debugging.html it doesn't seem to be too straightforward with debugging errors. and the error I'm getting, Object reference not set to instance of an object, isn't in their list of 'usual problems'

i'm nearly certain the error i'm getting is something similar to this https://dev.to/alexandlazaris/why-isnt-my-unity-web-request-running-in-webgl-build-1lfm but I want to figure out how to force the webgl build to give me alittle more information on the error message? or a good way to use Debug.Log (which does work with webGL) to diagnose this issue?

[astral wave]

what @orchid bridge said plus

[indigo crest]

Is it possible to run webgl pages on android/ios? The game would be very small, nothing hard for the phones to handle. Just 2d

[sweet oriole]

Increased support for mobile has been a recent development, so I would be careful with it. Do some tests and also try to evaluate other more web focused engines/frameworks.

[astral wave]

use 2022.1.16+ version and it will work on phones. Offcourse there will be limitations, like memory, the performance is heavily reduced, cant use VFX shaders and other limitations. But Most definetly can run on Phones

[indigo crest]

Thanks

[indigo crest]

haha, thank you 😄 makes it a lot easier

[fossil bramble]

has anyone experienced a slow software cursor in webgl?

Seems to lag behind 3 or 4 frames. Game's running at 60 FPS

[charred briar]

Also no problems here, if you have the alert dialog warning about mobile support, it can be disabled in the unity loader too if you want

We are still 2020.3.38 LTS across the board, it got the last somewhat clean QA from our team. But that specific build has some WebGL bugs to be aware of.

[sly wave]

Hello everybody. I have an audiosource in game with an audio clip attached and an audiosource used as the output of a videoplayer. Both are set with spatial blend = 1. From editor they work correctly, while from build webgl spatial audio works only for the first audiosource. Anyone know why?

Is it possible to somehow use spatial audio in webgl? if no, why in the first case it works?

[blazing pendant]

Is webgl available for mobile phones?
When I searched online I couldn't find a definite answer

[neon hawk]

Hi everyone, I noticed that in the latest Unity 2022 release notes support for the Mobile Touchscreen Keyboard has been added for WebGL "WebGL: Added mobile keyboard support for WebGL to enter text in UI input fields." However, I am still unable to get this feature to work with a build. What am I missing? Do I need to be using the New Input System? Any help is much appreciated.

[sweet oriole]

Messages from the past few days and the one right below yours sums it up pretty much. I don't know if Unity considers mobile support to be free of early version caveats, but it is actively being worked on and people are reporting some success.

[charred briar]

It works fine, a touch slow of course compared to PC. Are you seeing any issues on mobile?

[blazing pendant]

I haven't started my project yet.
I'm currently doing research into unity webgl, three.js webgl, and babylon webgl to see which is best for mobile

But thank you both for helping me 🙂

[halcyon pier]

for the life of me i cant still make a build that works on unity 2021, its just a black screen (i have no black ui ) nothing loads after unity logo and no errors

2019 works fine

any ideas?

2022 doesnt work too

has to be someone here who has this issue besides me

why 2019 works , 2021 > doesnt who knows

[charred briar]

You should learn all 3. I'd add to that Phaser, Aframe (based on three.js), and PlayCanvas. I've had to use all of 6 of those for a game at some point and each has some good advantages

Babylon - great for business applications
A-frame - better wrapper for three.js, good for games
Three.js - good for low level 3d
PlayCanvas - good for quick games with low use
Phaser - great for 2d web use
Unity - works if you don't mind the bloat and overhead

[sweet oriole]

What does "low use" mean here?

[charred briar]

PlayCanvas uses their third party servers, so if you are working on big games or things you'll own that matter - you likely won't want to use it long term. But that's just my personal opinion on it.

I thought they had pay-per-use licensing but it looks like they don't 🙂 which is handy.

[sweet oriole]

Oh yea the editor setup is a bit interesting. Technically the engine itself is free

[tawny cargo]

Is there a good guide for how to publish my Unity Game on my website? I have the WebGL file built

[charred briar]

I think the Unity WebGL page is the best place for the getting started info. I use FTP with a custom template for the index.html

[silk brook]

how on earth we adjust the game sizing ?
with memory performance ?

[sweet oriole]

Make sure you are uploading just the build and not the whole project. That is referring to the build size on disk. You can use something like https://docs.unity3d.com/Packages/com.unity.build-report-inspector@0.3/manual/index.html to visualize the data Unity outputs in the build log to see how the space is spent.

https://assetstore.unity.com/publishers/48890

guuuys is this asset compatible with webgl ?
do I need webgl input add on support ?

[astral wave]

If you use english leters only, or latin. No extra works is needed. Just go with new input system and no extra input is needed. Tho from what I see from this asset, you can use it freely in webgl.. Would I recomend it? no. Be a real man and use UI toolkit 😄

and from their implemenetation of minimap I would not go with it at all. The tutorial video shows extremly non perfpormant aproach, which will hurt you in webgl.

https://www.youtube.com/watch?v=kWhOMJMihC0&ab_channel=CodeMonkey

this would take you literally 15 mins to implement with way better performance and information.

In short, it will work. Would you use it? I dont think.

[cloud ermine]

what minimap ?
that's for registration form

[astral wave]

you send a link of all their assets, so I did not knew which one you are talking about, so commented on all of them.

[cloud ermine]

sorry I mean this one

[astral wave]

I didnt find any info what method they are using for sending emails. But from the way you writing your google account and password into editor....... If it is small project and you want use throw away account, go for it. If you are planning on making using on bigger project, I would strongly suggest investigating code very thoughtfully. As from video I cannot say if it is safe or not.

Depending on infromation you want to submit, it can be very dangerous

Most likely it is just webrequest post message code or something like that, which you can write your self in multiple ways. For prototyping it can be used without worries tho. I dont want to talk abad about the asset, as is seems well made, presentation is good, quality is also good, price not big. I Just expressing worries about security.

[cloud ermine]

find the tutorial on the youtube yet @astral wave

I need an inputfield, and a radiobutton

that stored somewhere, email is ok at the moment
used to be using firebase addon, but I'm curious with the add on above

[astral wave]

https://blog.unity.com/technology/ui-toolkit-at-runtime-get-the-breakdown

all code for UI stuff you need. Just need antoher script to submit webrequest to your server. is it google? is it private or what ever that differs. There are really really alot of tutorials online.

https://www.youtube.com/watch?v=4n6RT805rCc&ab_channel=CodeMonkey
https://www.youtube.com/watch?v=hN7tTL0tYzg&t=7178s&ab_channel=CodeMonkey

combine those two tutorials and you can do what ever.

anyways, webgl will not have any limitations on plugins you suggested. it will save you time. But will not teach you a lot. it depends on you which is more important to you, skills or time.

Time is very important and if you have money, just buy assets, you will be happier.\

[cloud ermine]

the video of the assets didn't showing the email to addressed where the data stored ...

[astral wave]

https://youtu.be/qdGinMIuCMk?t=28

client dont see it. But question is how you send it. For example if anyone will open google chrome debug tools and check network section what data they will see 😄

is password hashed? what servives it uses?

sending stuff from client needs to be always very carefull. If you send it from client to server and then to your mail. yea sure, no biggies, bet sending dirrectly and addind password in the message ? If code is not written carefully, it will be huge problem.

But once again, I did not see the code it self. I dont know how they implemented, there are ways to solve the problem! they might used it, I dont want to say anything bad about their product. Just saying you need to investigate it carefully.

[cloud ermine]

yeah that's the security reason, we really need to taking attention

Hello everybody

[astral wave]

hello ❤️

[orchid bridge]

Please let me know the difference firebox and chrome using webgl

[astral wave]

https://docs.unity3d.com/540/Documentation/Manual/webgl-browsercompatibility.html
https://docs.unity3d.com/2019.4/Documentation/Manual/webgl-browsercompatibility.html

In general it is almost the same you font feel any different. Firefox might load some things faster, chrome different things faster. It both uses webgl 2.0 so most thing is the same. Safarri have more differences.

[orchid bridge]

Thanks

[astral wave]

Hey...... quick question, can webgl build run on more than 60 fps on Chrome and other browsers?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????/???????? I was pretty sure 60 fps was the max.

Even if monitor is 144hz, it shouldnt be able to run on 144 right?

[orchid bridge]

right

[obsidian sage]

If I put my map-based Unity game up on multiple websites using WebGL, can each website have a starting location?

[sweet oriole]

Pretty sure browsers run the loop at monitor refresh rate.

[teal beacon]

can you add any more question marks

[astral wave]

your request, my command, edited the message.

[astral wave]

thank you.

[gleaming widget]

Hey

I'm sorry to bother you all, but I'm having some problems learning Unity and I'd like to ask for some advice.

I used the official Unity "ThirdPerson" template, then switched to WebGL and had problems controlling the movement of the character.

Dose anyone know how to fix it?

[novel cipher]

no, unless you tell us what errors you get or specify how it is not working

[gleaming widget]

emmm, first, I download the official template "ThirdPerson", and everything worked fine, once I switch to WebGL, I can't move the person.

This is the only error reported

[novel cipher]

did you install that starter package on your webgl project?

[arctic rose]

Did you do what the message says?

and you can clearly see another error below that

[silk brook]

where should I put this C# script ?

[silk brook]

does anyone acknowledge how to play video player on the online website services ? like itch.io & simmer.io ?

[silk brook]

it works fine on the runtime tho

[cloud ermine]

greetings !
can we increase WebGL Publisher limitation (200mb) with Unity Cloud service ?

[sweet oriole]

What is in your build?

[south socket]

i got this error when uploading a webgl build to itch.io

This can happen if build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present. Check browser Console and Devtools Network tab to debug

im on version 2022

[cloud ermine]

plenty of stuff it's 400mb in total

[sterile coral]

I need some help. I'm trying to get a WebGL build of my game, but it's not letting me access the player settings. Everytime I click the option, I just get a blank window with a dot in the upper left corner. This also happens if I access player settings through Windows and then click on the WebGL tab.

Note that everytime I try to access it, I get the following error code in the debug line that says "Index Out Of Range Exception"

Solved the issue...turns out I forgot to install the WebGL Build module

[hardy panther]

how can you implement browser-specific code?

#if UNITY_WEBGL
        _rotation.x += (Mathf.Abs(Input.GetAxis("Mouse X") - 0.05f) > 0.05f ? Input.GetAxis("Mouse X") : 0 ) * xSensetivity; // Attempting to prevent the firefox input drift bug
#else
        _rotation.x += Input.GetAxis("Mouse X") * ySensetivity;
#endif
``` I have these symbols that allow different code to be compiled depending on the build target, but I'd like to be able to tell what the user's current browser is so the code meant to counter a Firefox bug will only run on firefox

[marsh dock]

you'd have to write native plugin which will tell you browser/version

i'm not sure if there's something else available apart from user agent though / which is not entirely reliable /

[charred briar]

You can also pass JavaScript messages into the Unity WebGL blob and vise versa if you like

[marsh dock]

^ yea that interface is done via webgl native plugin as they call it (IIRC)

[cloud ermine]

guys anyone ever had this issues ?

[arctic rose]

Check the browser's JS console, like it says

But it looks like it's running directly from the filesystem which won't work regardless

[sly wave]

Hello everybody. Can anyone explain to me how browser memory is allocated in a webgl build? Which modules that I can find in the memory profiler are allocated in the browser ram? Only scene memory and assets? Besides the scene memory, how much memory is allocated to make unity work on a web page?
Thank you.

[sweet oriole]

You can find some info with pretty basic keywords
https://docs.unity3d.com/Manual/webgl-memory.html
https://blog.unity.com/technology/understanding-memory-in-unity-webgl
https://blog.unity.com/technology/unity-webgl-memory-the-unity-heap

Some potential builds to quickly get some basic memory usage stats (and bunch of other info)
https://github.com/JohannesDeml/UnityWebGL-LoadingTest

[cloud ermine]

meaning the modules just didn't supports webgl ..

[cloud ermine]

best way for you to do such thing might be with memory profiler
but it's only on the runtime
apart of that Unity 2022 seems have adjustable memory sizing

[cunning shell]

Does occlusion culling help improve WebGL performance?

[charred briar]

In most cases it should improve all platforms vs no culling - easy to test though to see by how much

[cunning shell]

May I know how do I observe the performance without building it and test it?

[charred briar]

WebGL specially handles garbage collection differently but most other stuff is the same from a rendering perspective. So it should give you some improvements

It won't help with memory or package size but will with GPU drawing and likely reduce battery use

But I'm definitely interested if anyone else has benchmarked it

[cunning shell]

So it wouldn't really helps in reducing loading time?
