[grave ember]

You are thoroughly unhelpful

[charred briar]

I'm sure you looked into this option, but my guess on that error is the device ran out of memory.

[mystic grotto]

Well yes, it ran out of memory, but why does it only occour on that device, and it also happens quite often on that device, but non other

[fallow fox]

can anyone help me, when i build webgl and open the index.html file, it would say an error. How do i solve this? I use 2021.3

[grave ember]

Opening the index file doesn't work for webgl, it needs to be on a server. Easiest way to do that is just by doing build and run and it will automatically open unitys simple web server.

[fallow fox]

ok, but how to open it subsequently or share it with others?

[grave ember]

To share it you will need to put it up on an actual website. If you want to reopen the simple web server for testing you can find the exe (don't remember the path off the top of my head but just Google it) and run it in cmd with a parameter of the location of your build.

For sharing something like itch.io is an easy free way to put it online.

[fallow fox]

Thanks, i would try it like this

[tulip drum]

has anyone here ever tried implementing voice chat with webgl?

[random talon]

Does somebody know where can I get a WebGL responsive template for latest unity versions? (2022.3)

[random talon]

I'm struggling a bit, when resize the broswer that it changes the camera fov

[oak tiger]

Hey everyone. We are having an issue where, we have a Database on a server and we Query it with Unity WebGl through HTTP requests (not HTTPS) to get the table associated with our computer name. This used to work in unity 2020 but since we updated to unity 2022 it stopped working. I noticed there is a new setting in player settings called allow HTTP requests and we have this set to always allow. Any idea what might be causing this? Anyone can help? Thanks 🙂

[jolly notch]

Is urp SSAO not working in WebGL?

[ruby nova]

Simply they defaulted Unity to accept only HTTPS for security, but as you have done, you can change it in the settings, or, you can use a proxy server to pass through the data: Client - HTTPS proxy - HTTP MyServer

[plain shard]

do you have a screenshot of your game / experience? what's your goal?

[plain shard]

what is the game / experience?

[tulip drum]

Building an mmo rpg, managed to get the voice chat working though using Agora, its cross platform too which is great and has spatial audio

[plain shard]

do you have a screenshot handy?

[tulip drum]

Screenshot of what?

[plain shard]

of the game

agora is a good choice

[tulip drum]

yea you can actually visit it at https://normies.ai, although we're in version like 0.0.0.0.1 lmao

Player sprite looks pretty awful we're working on a paper doll/player customization system at the moment so it'll be updated soon.

[plain shard]

gotchya

what is your goal?

there's a lot of stuff built here

[tulip drum]

An mmo, we don't have too clear of a vision of what the finished game will look like, one of the bigger things we're trying to do is add JEPA automous agents to the game.

[plain shard]

this is a school project?

[tulip drum]

If you make an account you'll be given a plot flag that you can place down to claim territory and you can place the campfires and sleeping bags in your inv

[tulip drum]

Nope, this is a company haha

startup to be more specific

[tulip drum]

We're trying to implement autonomous agents based off this paper: https://arxiv.org/abs/2304.03442

[plain shard]

do you have more than $25k of funding?

[tulip drum]

Far more haha, but the investments "we've" (I put quotes because im an employee) gotten aren't focused on the game but their investing primarily in 2 other products of ours which aren't related to gaming.

[plain shard]

i keep peeling, and i'm discovering this is an onion, not a banana

[tulip drum]

lmaoo

[plain shard]

i make unity games and services, i also author a lot of unity webgl engineering content. maybe instead of "what is your goal?", what are some of the promises you guys have made

[tulip drum]

We haven't made any promises yet as the game hasn't even been announced yet haha. But I think saying mmo rpg sums up what we're attempting quite concisely, there'l be crafting, a skill system, potions, iron smithing, dungeons, etc.

[plain shard]

gotchya

[tulip drum]

Also generative AI, so on top of the autonomous agents most npcs will have elevenlabs type tts and can speak directly to you based off your circumstances, rather than generic dialogue which you would normally find and isn't tailored to specific players

[plain shard]

are you in charge of all aspects of this game?

in practice?

promises can mean, to stakeholders besides players

[tulip drum]

Yea I'm the lead designer and programmer at the moment, we might hire an intern or possibly full time person soon though.

[plain shard]

cool

i am reacting to how much stuff is going on

which is good, that i see, a lot

what is your personal goal then?

like is it to make a game people like to play lol

is that the goal?

[tulip drum]

Yea the primary goal at the moment is a game many people would play, it's meant to be an mmo, we're hoping to eventually get 100k mau

bw if you're looking for a job let me know and send me some of your content, I'd probably recommend you if it's good, there's a good chance you might know who my boss/one of the cofounders is, I rather not say in this public discord though.

btw*

[tulip drum]

Do you see any errors in the developer console? Could be a mixed content error if the webgl itself is served on an https server

[ruby hound]

Hi everyone, having a WebGL build issue here I was hoping someone could help with.

Our project has initially been developed for VR, and is being converted to also support WebGL builds. I have followed the steps to get past the majority of issues with this (namely Oculus Integration Assembly Definitions and direct references to the Oculus package). I now have WebGL building and deploying to Unity's LocalServer.

However, as the build gets about 95% of the way loaded, I get a long error / stacktrace that culminates with: "Object.removeRunDependency" somewhere in my WebGLBuild.loader.js file.

TypeError: window.OnUnityLogMessage is not a function is also appearing

[ruby hound]

Update: the issue seemed to be caused by a package that we have in the project sending messages at startup. Resolved for now

[plain shard]

do you have a screenshot or link of your game? what is it

[random talon]

Do somebody knows if its possbile to initialize an embedded webgl in first place and only after pressing a button to actually boot it up and play?

[arctic rose]

What's the difference between initializing and booting up?

[random talon]

more that inizitialize i meant load. do you know when u load the the page and there is a loading bar? I want to keep at on start but "boot" the game not only when the bat has finished but when I want it

for example press a button "start" that i make on the frontent

[arctic rose]

Can't you just make the button in the game?

If you really want to do it outside Unity, edit the page CSS so that the game container is hidden by default and add a HTML button that shows the container

[high patrol]

why not utilize routing of an SPA to point to an Init endpoint that contains a button, and let the button route to the webgl game endpoint

[fallen sable]

its giving be this error?
Unable to parse Build/online game.framework.js.gz! 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: gzip" present. Check browser Console and Devtools Network tab to debug.

[turbid falcon]

What gives you the error?
Also, did you try disabling compression in the build setting?

[fallen sable]

so i did try disabeling compresion but i cant upload files larger then 25mb to github and the ucompressed file is 26mb, which is also a test run too see if i can even get it too work so im thinking the completed project will be much more

[turbid falcon]

Which file is 26 mb?

Afaik the size limitation is per file, not the whole project.

[fallen sable]

its called gym app.wasm

its in the build folder

[fallen sable]

ye, its per file my bad

[turbid falcon]

Is gym app the name of your project?

[sweet oriole]

Do you need to do this on Github Pages? 😛

[fallen sable]

yep

[fallen sable]

ye kinda, ik i can use itch, but i want it so when u open the link its just the project shown and nothing else

[sweet oriole]

I wouldn't use Itch either, but something like Netlify.

[fallen sable]

so i just had the idea of just grabing the link to what itch displayes and i now have a link to just the game and nothing else

i got it from inspect element

but now its giving me a ugly link, so i could teoretically just input the same src to a html run by github with the actually link that i want

so the issue is techinically fixed tnx guys

[stoic scroll]

My mouse clicks are coming in...for lack of a better word, slowly when playing my webgl game in Safari

I have to hold the mouse down for around half a second for it to register

interestingly, if I mash the mouse rapidly, it eventually registers a click

Works fine in Chrome (on macOS)

Keyboard input is fine, so it's just clicks. I wonder if the browser is trying to do something clever (and failing)

[plush pawn]

Who makes 3D URP Webgl games? How to optimize the game properly?

[stoic scroll]

that's a very broad question. have you figured out what's bottlenecking you?

[ruby hound]

Hi, having an issue with URP and WebGL builds on 2021.3.4f1. Anything using the URP Lit shader is invisible in build. Have tried a couple of fixes I've seen online (removing receive shadows from the material, setting surface type to transparent, regenerating shader includes) but nothing works. Any advice?

[sweet oriole]

I would probably upgrade to the latest patch version of 2021.3.31f1. Did you try in a clean scene with a static camera and a few rendered objects?

Doing a desktop build can be helpful to narrow things down

[plain shard]

do you have a game or planning to make one?

[plain shard]

do you have a screenshot of what it's supposed to look like, and a screenshot of how it looks now?

[plush pawn]

I have a game

[plain shard]

do you have any shots from the editor?

it will help communicate what you have

[plush pawn]

just the character and the box

I have 500+ fps in unity.

in the browser 140

in browser on mobile 40-50 fps

I can not figure out why on a cell phone in an empty scene slows down and drops fps

[spare hamlet]

Hello hello, I'm having and issue with my webGL build on itchio, the game runs the made with unity spalsh screen, but right after that, I receive this pop-up, does anyone knows anything about it? 🤔

[sweet oriole]

I generally assume it's something affected by things mentioned here with these kinds of errors https://docs.unity3d.com/Manual/ScriptingRestrictions.html
You might get more useful information in development builds

[plain shard]

do you have a screenshot of your game?

[spare hamlet]

Yooo thanks for replying, it's fixed already, I had a confusion selecting which scenes to build 😅

[opaque osprey]

Hello. I have a Unity scene added to my Blazor WASM (Single Page App). When the user goes to the page with Unity, it works fine. But, when they leave the page I get an error, which repeats until the browser crashes: TypeError: Cannot read properties of null (reading 'getBoundingClientRect')
at _JS_DOM_MapViewportCoordinateToElementLocalCoordinate (https://localhost:7201/Build/Build/Build.framework.js:3:27093) Anyone know how to prevent this?

[twilit sluice]

Does anyone know a free package or other way to create a file picker on WebGL?

[high patrol]

https://forum.unity.com/threads/getboundingclientrect-problem.1302099/

[opaque osprey]

Thanks. Yes, I switched to 2023.2.0a10 and it resolved the issue. I also had to implement a way to dispose of the JS library when the user navigates away from the page. hopefully it gets fixed in new updates

[golden summit]

So, I can't build any WebGL project, it just create a new empty folder. Can anyone help me (there's 10 to 15 errors in the console when I try)

I was just following the Unity pathway to learn and I'm stuck bescause of this error

[elder pelican]

Showing the errors would be a nice start.

[golden summit]

Oh, sorry

All the errors are similar, they tell me that there is "no module named '_ctypes'" but in another path with another script

And the console write "[Version and build] Build failed! 00:00:15.4654959

I use a Debian 10 OS and Unity 2022.3.11f1 with the WebGL module

[arctic rose]

This forum post suggests that re-installing Python might work: https://forum.unity.com/threads/webgl-build-fails-on-ubuntu-20.1490716/

[golden summit]

It don't work but it's definitely an error with Python

[golden summit]

I manually reinstall Python 3 and it finally works !

Thanx !

[gleaming granite]

Hello everyone!

I've been struggling for so long with the Cross-Origin Resource Sharing (CORS) issue when making requests to APIs using UnityWebRequest in WebGL applications running in the browser. I've researched and tried various solutions, but they all seem to introduce layers of complexity I'd rather avoid.

Has anyone tackled and resolved this issue in a way that could be considered "elegant", "simple", or even "ingenious"? Any advice or experiences you could share would be greatly appreciated.

Thanks in advance!

[arctic rose]

There's only one reasonable solution, depending on whether you control the API or not. If you do control the API, add the correct CORS headers to its responses. If you don't, you need to make a proxy server between the API and the game.

[gleaming granite]

I was trying to avoid having to use one of those two ways to solve the problem. So there's no hope beyond those options...? 🥹

[arctic rose]

It's a security feature. If there was an easy way to get around it, it wouldn't be a very good one

[gleaming granite]

That makes sense, thanks. Any good advice about the proxy way to solve this thing?

[arctic rose]

It should be relatively straightforward depending on the API. There should be plenty of resources online

[gleaming granite]

thanks, I will try my best 👍

[plain shard]

do you have a screenshot of your game?

it will help me understand where you are on your journey

[gleaming granite]

I'm not making exactly a "game". I'm full experimental mode creating a lot of concept apps and experiments using AI models, but I want to run them in browser connected to APIs, and here is where I have the problem 😅
https://twitter.com/ilumine_ai/status/1678394578854969344
here are some interactive samples:
https://huggingface.co/ilumine-AI

[plain shard]

are you fal.ai

[gleaming granite]

no, but I've been trying to find a solution with them (still talking)

[plain shard]

can you visit https://appmana.com/watch/virtualtestdrive and click drive and drive the car around? and try it on your phone too? do you know what you're looking at, technology wise?

[gleaming granite]

what is this for?

[plain shard]

this is to avoid using webgl entirely. you "just" have a streamed machine, but it's very powerful, but it's not a VM, it's not virtual desktop, it's not furioos, it works on mobile, it loads instantly, etc. etc.

so if you need to call an api, it Just Works. indeed you can use however much memory you want, you can even run models locally, if you choose, straight out of e.g. a comfyui workflow, for example, which i maintain

does this sound interesting to you?

[gleaming granite]

I think this goes beyond my needs right now 😅

[plain shard]

might make your life easier your demos look nice

perhaps if you had to deal with less webgl crap and could just push to git you will have more time to do cool things

[gleaming granite]

I'm good for now with webgl, I just need those web requests working in my projects 😶

[tropic patrol]

does anyone has performance issues with firefox? my game run smoothly on chrome (60fps) but on firefox I have like 20, I checked hardware acceleration and it's enabled, both browsers are on latest release

edit: turns out using a video player, even with a 640x480 resolution has infamous bad performances, does anyone has an alternative to use?

[plain shard]

do you have a screenshot of your game? what are you trying to do? using a jslib to play a video can be done

[tropic patrol]

well I have a video player and a render texture the video is rendered to, which is applied to an arcade prefab

that’s not fancy but it gets horrible performances on firefox, it was taking like 74% of the resource for one frame

[outer wave]

We've no multithread support, right? Trying to parse like 5 dictionaries worth of words (chopping them into multiple different substrings), so anything to improve loading times.

what about compute shader? Maybe I can work with that.

[plain shard]

The solution is complicated. What is the game? Are you trying to make a trie?

[outer wave]

just some word game where you're presented with substrings to construct words out of

[plain shard]

I suppose you can ticket Unity. It really depends if you want a workaround or a solution.

[plain shard]

What is the data structure you are trying to make?

Not the one you start with. I get that you start with lists. What is the data structure you are turning word lists into?

Or is the answer “none”?

And the word lists, how do they get into your game? Are they in your Assets/ directory? Are they downloaded from the web at runtime into your game?

[plain shard]

Because no you don’t have multithreading. You shouldn’t be parsing at runtime.

[outer wave]

Ah, ok yeah it's been a while but I've it parsed already from some python script my mate made

[plain shard]

Answer my questions though

[outer wave]

I think the problem is object construction from reading it in from json

[plain shard]

Try to reply to the questions specifically @outer wave

[outer wave]

I'm using streaming asset folder for webgl

[plain shard]

Okay

[outer wave]

actually need to fix that now cause betterassetstreaming api doesn't work with webgl apparently

[plain shard]

Can you reply to the data structure question

[plain shard]

This is a bad idea. It provides no advantages. The long delays you’re observing come from many factors, a significant one comes from using StreamingAssets

Stay focused on my data structure question

[outer wave]

sec trying to navigate what I was doing lmao

[plain shard]

So the answer is “none” then or “a mess”

That’s okay

[tropic patrol]

I don't think that would be useful. I spent hours and hours for an issue about 3D audio with a video player and its audio source. Turns out it's a bug from unity, it plays it full blast at center, but if I sync a separate audio and video component manually, 3D audio works. Sent it to the unity bug tracker, they said they can reproduce it, and after a while, "Won't fix"

what a joke

[outer wave]

nah, it works fine. Just ive left with loading issues which are apparently on webgl but not android

[plain shard]

I’m said it was okay

[outer wave]

and I think it's because of the streaming asset like you're saying

[plain shard]

It’s nit

Not just that*

I mean I know know few of the facts,

[tropic patrol]

I wish I would have tried cocos or godot before buying assets and stuff.

[plain shard]

And I’ve made word games, typically you store the word lists in a data structure, like a trie, that is useful for these sorts of games

Or maybe it’s a Dictionary

There’s a big difference

[outer wave]

Yeah, I actually started with parsing because these dictionaries are like many mbs in size

[plain shard]

Or it’s a List

[outer wave]

but im looking at it now and I just chop it up ahead of time

[plain shard]

You’re saying dictionaries, and they’re word lists right?

[outer wave]

right

[plain shard]

Okay but if you have text word lists that are just smaller files

So the answer is a mess right?

Like what’s the data structure in memory in C# these get turned into?

You can’t solve this problem without the answer to that question

You can try and figure that out eventually. It can be a long journey or a short one

Sorry I’m not trying to be annoying

But ultimately to make it load fast, you will have to put, in your Assets folder, a binary file that is the in memory representation of the data structure you need. Then you can load it directly without parsing.

You haven’t done any profiling so you’re just spitballing. But if you do, it will be loading the files and the parsing that will be incredibly slow

They are just as slow on Android, it’s just that the StreamingAssets folder is already there, and I don’t know how you do the parsing, it may be non blocking

[tropic patrol]

he could make a small C++ program to load like a .csv or .json file and convert it to binary, and then load it directly, that would be convenient for updating its structure whenever he likes

[plain shard]

I think it’s going to be one of those blub solutions. He may have blocked me. I’ve done a WebGL word game so I’ve gone on this exact journey

[tropic patrol]

what? why did he blocked you

[plain shard]

Dunno

[tropic patrol]

@outer wave be polite

ridiculous

[outer wave]

what

[tropic patrol]

[outer wave]

I'm looking at the streaming asset folder stuff

https://github.com/gwiazdorrr/BetterStreamingAssets
I use this for android with no problems but it doesn't support webgl so I was just using the general streamingasset method

Just trying to figure out where I left off here with webgl, but I know that async methods werent working

[plain shard]

Okay but forget about that

Please try to answer my question

Are you saying you just have List<string>?

[outer wave]

It's Json into a list that's it

[plain shard]

Just to confirm

You mean a List<string>?

[outer wave]

list of structs with the strings

[plain shard]

OKAY

Can you show this struct?

I mean show the code

List of structs

Like literally the field and the struct so that it’s unambiguous

[outer wave]

https://hatebin.com/qaezmopvcb

[plain shard]

Okay well everything in this file is going to be slow

Especially in WebGL

Zip, parsing, big memory allocations

Downloading

And all at runtime

So you’ll have to rewrite it

[outer wave]

right it's that I made it for android and thought webgl was light enough to port it over

[plain shard]

But I’m glad you shared it

[outer wave]

but apparently can't use a lot of my async methods or apis

[plain shard]

You can read my pinned tips and tricks on WebGL on the forums for more info

Well do you want to rewrite it?

[outer wave]

probably will look into it as it would be nice to port it over

[plain shard]

Do you understand what I mean by “representation in memory”?

You will do textasset.bytes

Then those bytes go into the constructor of an object that is like “WordListStorage”

And its methods are whatever you need to query, and it does O(1) arithmetic on the bytes to get the strings or whatever

No transformations at runtime

[outer wave]

it's not the cleanest in general even for android, but I can see what I was trying to do the last time I picked up on this

[plain shard]

Try to model the end result of the parsing that you need for your game as a single instance of a class

[outer wave]

but I've actually experimented with some other general ideas and yeah, it's down to a memory issue here

[plain shard]

Then you can read online how to model the individual parts of it from a span of bytes

[warm talon]

Hello. Can anyone help me with this

[high patrol]

Implement a robust communication layer that can handle large files by segmenting them into smaller ones and reassembling them on the receiving side

[plain shard]

why are you downloading asset bundle files through firebase?

also, are you aware of the limitations with loading assetbundles in webgl?

also, what do you mean by memory leak?

do you have a screenshot of the game?

[gilded cedar]

hey all
does anyone know how these errors could be fixed? i tried searching online but none of the solutions that mentioned the same errors worked (tried rebuilding all assets, tried deleting the asset cache, tried force downgrading then upgrading and reinstalling the toolchain package, none of it worked)
they only show up when switching the build mode to webgl, and they happen in every project (even tho i build a few webgl games already, and none had this happen)

[hexed atlas]

Hello fellas!
I'm currently working on a project that might work with a good audio and microphone I've worked before with Wwise but it seems to don't support WebGL. Maybe someone know the best path to take on this sound engineering? Thanks! @here

[plain shard]

what is the game & the audience?

[hexed atlas]

Its a simulation on webgl so you should be able to talk with other folks on real time.

[plain shard]

why is it in webgl?

so it's not a game? it's like a training?

like it's an industrial application?

or a branded game / ad?

[hexed atlas]

Its like a weird mixing of habbo and roblox, but one of the conditions is to get entirely on webgl

[charred briar]

There are lots of options in that space. Photon Voice. WebGL Voice & Text asset, etc.

[plain shard]

but why does it have to be pure webgl? what is the audience?

it's just a really bad fit for webgl

who's going to use this for more than 30s but wouldn't bother to install?

[charred briar]

We have lots of clients with XR simulations that need them for WebGL as well, its pretty standard in education.

[plain shard]

does this have to work on phones?

[hexed atlas]

Yes

Dude, it's not my business haha

I'm just the guy who does it

[charred briar]

We had to create something for our SocialVR platform as well, to let browser users join the same community and participate 🙂 It's pretty common imo.

[hexed atlas]

Thanks for the recommendations!

[plain shard]

does it also have to support phones, in webgl, on mobile safari?

[charred briar]

This is probably the quickest way to get started with it these days WebRTC https://docs.unity3d.com/Packages/com.unity.webrtc@2.4/manual/sample.html

[hexed atlas]

Not for now. But it will.

[plain shard]

do they have a budget?

i can tell you now, the webrtc package is not something you want to go down

[hexed atlas]

Yeah, they have

[hexed atlas]

Probably I will get into the already-created assets for this

[plain shard]

is it going to be like a 2d pixel art experience, or 3d move around your anthromorph in 3d person?

[plain shard]

yeah i hear you. i'm trying to be helpful there's a punchline to all of this

are they making their own art in 3d?

[hexed atlas]

Its an immersive 3D work, that's why I need a good sound system

[plain shard]

got it. and it's original assets or scanned assets or...

like when you say immersive do you mean photoreal 3d assets?

[charred briar]

What are you using for networking in the existing version?

I'd definitely stay close to that if you can. So if it is photon, adding photon voice, etc.

[hexed atlas]

We're struggling with mirror and playfab

[hexed atlas]

Yeah, I saw some stuff pretty cool on photon, but its not the case

Gotta go guys, thanks for the recommendations!

[charred briar]

Yeah with mirror, you'll end up needing to create something manual, imho.

[plain shard]

i build a pixel streaming platform you can easily try, for free, if you so choose. you can achieve multiplayer by having multiple people share the same unity instance, so like a local multiplayer game. and wwise would just work. but i'm trying to understand what precisely it is that you're making

i'm not trying to be annoying

most people will bounce waiting for something to load

so that's why i was asking if it was an ordinary video game - generally people are willing to wait for those to load - but if it's something that gets an audience inbound from e.g. instagram, tiktok, cocktail parties the creators of this experience go to - webgl is impracticable

[frosty idol]

I have a couple of questions

1. Why does profiler show me ~60 fps, when the game feels like ~10?
2. Does NavMesh work differently on WebGL?
   I'm rebuilding the navmesh frequently and it works fine on mobile, but not on WebGL.
3. Can the performance be improved?

https://youtu.be/mQ8PrNZtI88

what browser & platform are you using to play the game?

[plain shard]

try setting this to true https://docs.unity3d.com/ScriptReference/PlayerSettings.WebGL-threadsSupport.html

@frosty idol you will have to correctly configure cross origin policies if you want multithreaded support in mobile safari

[frosty idol]

Unity 2022.3.9f1
Firefox 117
Win 10
CPU (4/8 @3.6Ghz)
GTX 1660

I've tried to set this bool to true
And got an error
Uncaught (in promise) Your browser does not support multithreading.
So, it seems that firefox doesn't support multithreading out of the box.
Will try to tweak some settings.

Tried to turn on everything thread related, but no dice.

Upd: tried google chrome, the error is still here.
Upd2: tried to set 'hasThreads' to true in the 'Web.loader.js', the game started, but the performance is the same.
Upd3: it worked in google chrome at least
Upd4: it stopped working, when I've tried to upload the build to itch.io

[plain shard]

when you test threading support, what is the URL you visit?

if it's an ordinary, WAN accessible domain name, write wan-domain.com

[frosty idol]

After multiple tries to make 'MultiThreading' to work, I've abandoned this idea.
Also, the game runs smoothly in the Google Chome.
So, it might be that Firefox WebGL renderer is just slow.

How to use .env files in Unity WebGL build?

In Emscripten recommends to use ENV variable and presetup it with Module.preRun

Emscripten-generated JavaScript cannot access the computer’s environment variables directly, so a “virtualised” environment is provided

// *.jslib
mergeInto(LibraryManager.library, {
  Message: function (str) {
    console.log('Message', UTF8ToString(str), ENV.NEXT_PUBLIC_DOMAIN);
    window.postMessage(UTF8ToString(str), ENV.NEXT_PUBLIC_DOMAIN);
  },
});

• Emscripten cannot access to process.env
• I need to get NEXT_PUBLIC_DOMAIN value only
• I can run build with command line using custom Build class:

using UnityEditor;
using UnityEngine;

public class Build
{
    static void WebGLProductionBuild()
    {
        BuildPlayerOptions buildPlayerOptions =  new BuildPlayerOptions();
        buildPlayerOptions.scenes = new[] { "Assets/Scenes/SampleScene.unity" };
        buildPlayerOptions.locationPathName = "Build";
        buildPlayerOptions.target = BuildTarget.WebGL;
        buildPlayerOptions.options = BuildOptions.None;
        BuildPipeline.BuildPlayer(buildPlayerOptions);
    }
}

With following command:

. .env.development && Unity -quit -projectPath . -batchmode -executeMethod Build.WebGLProductionBuild

[plain shard]

yes, multithreading only works when two headers are set

[plain shard]

i wouldn't overthink it. simply copy the public domain value. next inlines the variables in your client code.

even if you achieved your goal of "using .env files" it wouldn't resolve your issue, because that's not how next works

if you want to access a value from the page, it seems you already know how to do that

[jade flame]

I want to send value to the page from the Unity WebGL app, which is here a wasm code read by Emscripten.
In Unity documentation recommends to duplicate class method in *.jslib file so when it called the same method in jslib file will be called.
https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html

So, here will be called window.postMessage, where in second argument need to pass the page address to strict application by which address it will be listened.

Always provide a specific targetOrigin, not '*', if you know where the other window's document should be located. Failing to provide a specific target discloses the data you send to any interested malicious site. https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage

What I want to archive, to make a template for Unity web apps, where I can specify that targetOrigin in one source of frue so inside unity app I send message, and inside nextjs app - listen it.

The path I chose is not easy one, but I don't want to store any secrets in the repository, so I decided to use .env files both in NextJS and Unity code.

[plain shard]

what are you trying to make?

i am not sure what the issue is here, you don't need to interact with next.js's unusual public variable configuration inlining thing at all

[jade flame]

ok

[plain shard]

what is your goal?

why are there popups or same origins? what is the game / experience?

[jade flame]

I already did that I want. Now, my goal is to improve it.

[hexed atlas]

Hello guys! I've been really stressed trying to deploy on webgl using some playfab services for multiplayer. Maybe can someone help me with this? 😦

[plain shard]

what is your specific issue?

[hexed atlas]

The multiplayer system works pretty fine on windows and android, but it does not on webgl

[plain shard]

what is the context of these error messages? they are obviously meaningless by themselves

like describe what you are doing

and then why you looked in devtools in the first place

are you confident playfab is supported in webgl? what are "some" services?

oh yeah you were asking questions earlier

[plain shard]

do you have an urgent deadline?

[hexed atlas]

Yeah

[plain shard]

did you author the windows and android version?

what exactly isn't working in the game?

[hexed atlas]

Yes

[hexed atlas]

Doesnt connect from client to server

[plain shard]

i think the first step is identifying where these exceptions are coming from. you can make a development build and enable demangling in order to see a real stack

-sDEMANGLE_SUPPORT=1 is the additional emscripten compiler args although i think that's automatically enabled by checking Development nowadays

[plain shard]

so these errors appear when?

when you launch the game? are you confident they are associated with "connecting?" what does that concretely mean, connecting via mirror?

are you trying to use mirror peer to peer with webgl?

[plain shard]

maybe the first thing to do is to ask for more time and money

[sweet oriole]

People are going to have a hard time helping you if you don't provide enough information about your setup. References to KCP suggests to me that you aren't using a browser compatible transport. Mirror has a WebSocket transport available if that is what you are using.

[desert nexus]

What version of webgl is ued by unity in the web platform?

[sweet oriole]

2.0. 1.0 is available in older Unity versions.

[drowsy crane]

Anyone heard of using webGL as a way to let people use multiple mobile devices as touch controllers for a game running on a PC as non-web-gl?
Would want the mobile device to just display joystick/buttons & transmit data to the game.
I've kinda implemented a non-webgl solution last year that used websockets to send touch info to a nodejs server running on the PC & then sent that data to unity via redis. But curious if a webgl solution might make more sense?

I setup 360 projection-mapped geodesic domes as an Art Installation and have a game that let's someone fly the dome around space with a joystick. I'm adding multiplayer to it where people can use their phones to interact

[frosty idol]

Greg has made something like that in the past
But it's unsupported.

https://github.com/greggman/HappyFunTimes

[plain shard]

you can read about unity's input system remoting features, which i believe have been used by various assets or an official unity package (maybe, i don't remember) to allow you to attach a browser and its supported inputs as a user to a running, remote unity instance. this is how appmana, my unity game streaming solution, connects browser inputs to a remote unity instance.

[plain shard]

how buggy do you want this experience to be?

[drowsy crane]

Less buggy is better but it's really just a fun side project for now

[drowsy crane]

This looks really interesting!

[drowsy crane]

What problems have you run into using the remote input like this?

[crude atlas]

Sorry for the delay, but yeah, the right gets the grass to spawn and render, and the left it’s not visible… if shadows are turned on however, the shadows still appear just the meshes have their alpha turned down to like 0.1. (It’s for my game dev coursework… we’re only allowed to use 3D primitives included in unity, no external stuff is allowed)

[plain shard]

it works very well. it's just a pain in the ass to set up

pretty much flawlessly

you will have to understand how input system works. that is the main obstacle

you can of course reinvent input system yourself

that's all you'll end up doing if you do the blub thing of like
oh i need a class that represents each user
now i have to associate a remote connection with a user as a device
now i need some way of representing the touch...

input system has already done all that

does that make sense?

it's a huge amount of IT either way

InputSystem.QueueEvent allows you to pump input system events from anywhere, that is the single simplest way to remote input. you can also assign a user and AssociateDeviceWithUser. then you basically have a local multiplayer experience

[plain shard]

hmm i'm not sure what the issues are

[drowsy crane]

Gorcha, thanks so much for the info!

[plain shard]

i think you're gonna wanna blub it

how much do you want to do input system

[drowsy crane]

Not sure - you're making me think maybe I don't wanna use the input system haha. I'm comfortable just blubbing, I'm not gonna be getting too complicated with things I think

[proper stone]

whats the best way to fake a cloth simulation in webgl?

[charred briar]

You could use bones, joints and sphere colliders in most cases

[plain shard]

you can try obi cloth and see if its performance is acceptable, as afaik burst accelerated compilation does not support webgl

[proper stone]

I found that simulating in blender and then converting to shape keys and exporting to unity as fbx works pretty well

Had some problems with file size but I’m good now

[charred briar]

Yeah that'll work too

It wouldn't be physics reactive but might not be needed anywya

[glacial barn]

all this shows me is my camera feed after it loads. what is the objective? do you need markerless AR in a way that works for mobile safari?

it's an asset living in 3d?

[ashen matrix]

Ist is an Avatar hat you can Place markerless. If you try to pinch scale ist crashes 😦

[plain shard]

this is streamed and using HDRP. so you can test AR from the editor directly, and exactly what you experience is exactly what is deployed to everyone. would you prefer to use this approach?

there's no webgl. it just loads instantly, and all you have to do is push to git. you never have to build yourself.

this works on mobile safari, as you can see

[haughty lynx]

Hey! I was wondering if it's possible to share a link that would open the game in webgl redirecting directly somewhere. Like for example I'd share a link of the game url with an id "app.site.com/id" and reading the id from Unity and then do something in the game based on this id

[arctic rose]

https://docs.unity3d.com/ScriptReference/Application-absoluteURL.html

URLs in the form "app.site.com/id" requires server setup, query parameters (app.site.com/?id=123) work without special setup

[haughty lynx]

How would that work? Or is there an alternative of having an id in the url?

Oh okay I read wrong, so I could use app.site.com/?id=123, and then retreive this info via Application-absoluteURL?

[arctic rose]

yes

[haughty lynx]

Working perfectly ty very much

[glacial barn]

From the following can anyone tell what could be afecting more performance in unity webgl?

• Shadow Caster 2D from URP (around 50 objects with the script)
• Vector Graphics for sprites (around 50 objects in a scene) : https://docs.unity3d.com/Packages/com.unity.vectorgraphics@2.0/manual/index.html
• Just URP lighting in general (around 10 lights per scene)
  (or none)

The thing is, it's a very simple 2d game but the more objects I add to the scene, the more it lags on PC... it's bad

Profiler doesn't seem to show any problems performance wise. But it runs well on the editor

[charred briar]

I don't use URP, so I can't weigh in unfortunately

[plain shard]

can you share a screenshot of your profiler when connected to the browser player?

[glacial barn]

Well seems like it's the shadows...

right?

I have a low/medium end laptop (that's why fps are relatively low)

[plain shard]

yes. shadows (1) are ordinarily submitted as jobs (2) webgl is single threaded (3) you probably want to use culling / limit the number of game objects your lights can illuminate, because this looks pretty excessive even for 4 lights

[glacial barn]

Interesting. Doesn't culling happen kind of automatically in unity 2d?
There is only one light that creates shadows actually. this scene has a total of 61 shadow casters...
Might Shadow Caster 2D just be a bad solution?

Are there any other solutions for this?

[glacial barn]

All shadows disabled

[glacial barn]

Ok the game actually runs at 60fps on the phone without the shadows lmao. previously it ran at like 15 fps

Are we sure this Shadow Caster 2D script is not actually poorly written by Unity? Is this really not a bug?

URP version 12.1.7

[deft sandal]

is it possible to save info to something like a password manager?
Anything that would trigger a "login" to save login info?

I was thinking that I could possibly hide a username + password input on the page, and just edit them manually with some js function every time the webgl inputs are changed.

but that feels super hacky.

[plain shard]

i'm not sure. i think yo ushould configure your lights carefully and not make any assumptions

[ashen matrix]

My webGL built Users in Safari the ear speaker and Not the handsfree speakers. So it is too quiet 😦
How can i handle this? 😦

[charred briar]

Maybe just need to switch the audio device? https://docs.unity3d.com/Manual/class-AudioSettings.html

[glacial barn]

true, I tried a few changes to the lights, doesn't seem to improve performance...
Do you know of other solutions to this?

Or does anyone know any "alternatives" / fake 2d shadows instead of Shadow Caster 2D?

[plain shard]

it's likely a bug that it performs so poorly, i agree with you. i would at least ticket your scene. i am not sure of alternatives

[glacial barn]

Sorry for the dumb question, but where would I "ticket" my scene?

[plain shard]

report an issue from the editor. it will prompt you to attach your project

[charred briar]

When you can't find info in the profiler you can spot check too. Try disabling all lights or all but one and do a build. If that runs well at least you know the culprit.

In 3D space, real-time lights are very intensive. But you can tell via profiler and seeing the batch and poly counts massively increasing in the stats view

no just accessing the clipboard directly

a button that just pastes the text into the game

it works in engine but not in webgl

[glass cloud]

i dont think thats what im looking for

im pretty sure thats referring to ctrlc ctrlv

[sweet oriole]

Yea I guess systemCopyBuffer support isn't a given in that change. If it can be accessed in JS, you can use browser <-> Unity scripting to implement it https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html

[errant cipher]

So is there any way to get Cursor Lock working in WebGL for something like a third person camera. Where you right click, it locks, you orbit the camera around, then unlocks when you let go of the right mouse button. It always needs a second input from the keyboard or left click to actually lock which is not normal behavior.

[errant cipher]

For anyone trying to do cursor locking in webgl, the solution is to call into native js with a .jslib file in unity.
Jslib:

mergeInto(LibraryManager.library, {
  LockCursor: function (lock) {
    canvas = document.querySelector("#unity-canvas");
    if(lock){
        canvas.requestPointerLock();
    } else {
        document.exitPointerLock();
    }
  }
});

C#:

#if UNITY_WEBGL
[DllImport("__Internal")]
private static extern void LockCursor(bool @lock);
#endif
private bool _isCursorLocked = false;
[Conditional("UNITY_WEBGL")]
private void CallLockCursor(bool @lock) {
    LockCursor(@lock);
    _isCursorLocked = @lock;
}

[main shale]

right click, two fingers touch or esc or tab than on update check the key and call mouse pointer lock, just on build js file gets overwritten.

[daring root]

good afternoon, I got on this server since im looking for help with my first unity project. The colliders of my game are working correctly on the editor window but when i try to build they dont work, I tried debugging to make sure the colissions were detected and the collisions did log in. I made sure the player object and the walls were on the same layer and made sure an 2d physics that the collision matrix was in order.

[lucid raptor]

You're going to need to provide much more specific info for people to want to engage with this. What's your build platform Edit: yeah my bad didn't notice i was in the webgl channel lol

trying to upload a game for a gamejam but the music tracks sound crackly, the first one is in the editor and the second one is in the build

though the crackling only happens on 3 tracks that i have overlayed on each other to get an adaptive music system, does the volume changing cause this?

[charred briar]

I usually change the sound more subtly. Adding a volume as a target, and then slowly fading to that volume over time via an update or coroutine. That way it's a lot smoother with less spikes and it rounds off the unexpected peak changes. Depending on those stats that volume could change all over the place

[vocal vapor]

I don't know if there's a better way, but possibly look into Application.platform, if there's no good #if compiler conditions to check for.

I found a solution, I'm using InputSystem.GetDevice<Touchscreen>() to check if it exists

Splashscreen loads a MainMenu scene with a UIDocument

MainMenu UI has a button that queues a scene to load, the LoadScene is done in Update.

The new scene loads, with its own UIDocument that has a button, that queues returning to MainMenu scene, also loaded in Update.

Problem
The MainMenu UI does not load when returning to it.
This only occurs when playing a WebGL build.
It does not occur in WebGL Editor, or in a Windows build.

Error
The only error that seems to happen around the same time:

InvalidOperationException: Stack empty.
at System.Collections.Generic.Stack`1[T].ThrowForEmptyStack () [0x00000] in <00000000000000000000000000000000>:0

Observations
Two notable variances:
#1) Build a UIDocument in my script in Start(), with AddComponent<UIDocument>() - The error occurs during that call.
#2) Have existing UIDocument, accessed in Start() with GetComponent<UIDocument>() - the error occurs before .Awake(). GetComponent will return a UIDocument; however, rootVisualElement will be NULL.
#3) One UIDocument on a different DontDestroyOnLoad() object, using this.uiDocument = different.GetComponent<UIDocument>() - The error occurs during uiDocument.panelSettings = this.panelSettings.
#4) One UIDocument on a different DontDestroyOnLoad() object, like #3; however, this time not overwriting the settings/asset, instead .Add() to the existing root. - The error now occurs during menuUI.visualTreeAsset.CloneTree();

[vocal vapor]

I added another Test Observation (3), that has similar behaviour.

I wonder if I should move this to (or mention this on?) the ui-toolkit channel?

I'm starting to feel it may be more specifically UIToolkit related... even though it only happens in a WebGL build.

[I don't know how to move a message on discord, though, if I should. (?)]

Edit
And added #4.

[hallow sequoia]

@vocal vapor Are you still working on this? Can you share the entire stack trace where you pulled InvalidOperationException: Stack empty. at System.Collections.Generic.Stack from, if so?

[vocal vapor]

I very much am still working on this... for three days now x.x
I tried recreating it in a brand new scene, but wasn't able to. So... it's got to be something I'm doing, somewhere.
I've taken to copying the entire project, and am slowly ripping out every component to try and narrow down the culprit.

https://pastebin.com/GsmCSUcX - I didn't want to paste it here, it's a lot.
[Or alternatively, let me know how else I should paste large content]

What's really fun, now, is the latest version I'm testing...
I can go into the game, then back to the menu, 3? times, give or take. Before it does the breaking (as earlier described)

[hallow sequoia]

I've taken to copying the entire project, and am slowly ripping out every component to try and narrow down the culprit.
Good idea to try and isolate the issue from the rest of the project.

I can go into the game, then back to the menu, 3? times, give or take. Before it does the breaking (as earlier described)
My intuition is wonder if there is a memory leak somewhere...? Especially if the issue doesn't show up until something happens after a certain point.

[vocal vapor]

I'm wondering if there's a memory leak, as well. Possibly a missing -= event, maybe. I'm not sure yet. This copy of the project should provide more answers; I just need more time to continue widdling it down. I'll update with what I find... either some silly thing I missed, or a simplified sample project to example the issue.

[hallow sequoia]

I just need more time to continue widdling it down
I'd say you should be building it up instead. Presumably you'd be able to easily add the elements in an empty project to know if the scene transition mechanism.

You should probably use the webgl profiler too; though, I haven't used the profiler on a webgl project (yet). I have used in the editor and on desktop applications.

[vocal vapor]

It's a lot easier to tear down in this case, than build up.

I've not managed to get the profiler attached with WebGL. Memory Profiler attaches, but regular Profiler doesn't; haven't figured out why. Though I could use MP to check before/after each load... see if it might be a memory leak. Hm. I'll try that on the next test, after this pass on disabling things.

[hallow sequoia]

It's a lot easier to tear down in this case, than build up.
Hmm sus... Asking for curiosity: why?

[vocal vapor]

To me, at least - It's a lot easier to prove the issue is still happening, after removing things - than it is to spend time adding things, not knowing if what you added will be the break.

Memory Profiler showed pretty consistent ~452MB, so if it's a leak, I don't think it's significant enough to be the issue of taking too much. Unless there's an accessor happening somewhere (which is my lean towards a missing event unregister)

[charred briar]

Yup that's usually the best way. I usually recommend removing half of the potential culprits each time, as opposed to one at a time, when there are quite a few possibilities. Urp. Models. Enviro. Shaders etc. It can greatly speed up the narrowing down process.

It's probably important to mention memory works different on webgl as well. As garbage collection can't happen immediately, it happens on the next frame. So even a lot of json/linq string requests can build up a crazy amount of ram between frames

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

[vocal vapor]

I think I finally got a clue, with a new error message around the same location:

InvalidOperationException: Failed to Free handle with Index=0 Version=0

This new error lead me here-
https://forum.unity.com/threads/1391191/
Which has a link to another bug report, which further has more links.

I think this might be the bug I've been fighting for the past 3 days.

Though one of my tests, did leave the root UXML, and only added/removed elements. So I'm not 100% certain it's the same thing; but, it's a big clue.

[weary wasp]

Hey guys, with a WebGL build is there a way to interface with the website code?
I've used a .jslib file but I want to import functions from javascript that is included with the website
outside of the Unity build.

[arctic rose]

#archived-code-advanced message

just call the functions

The functions you want to call must be in the global level

[worthy pier]

🆘 🆘 🆘 Help 🆘 🆘 🆘
anyone have suggest unity webgl ar plugin Free and some one time purchases asset plz help me

[charred briar]

I've had a great experience with MindAR. There is a Unity plugin that's free and they have their own more complex paid one.

In the future I wouldn't post my question in multiple channels, and this hardly seems like an emergency to me.

Personally I prefer WebAR to not go through Unity though. Much easier and lighter to work through typescript m

[weary wasp]

The functions you want to call must be

[vocal vapor]

I finally found the "smoking gun" culprit that changes "make it or break it" in my situation:
SceneManager.LoadSceneAsync() - This will eventually break UIToolkit. Even if the old scenes are being unloaded.
SceneManager.LoadScene() - This, as of yet, does not.

When building my day-1 reproduction test, I accidently used LoadScene, which was a deviation from my actual project code. Resulting in a sort of 'false positive'.

Granted, the issue is not specifically related to SceneManager - just, that is a key component to reproduction.

If anyone wanted to see the issue for themselves, I made this during my testing (and looking for potential workarounds).

https://github.com/BadgerMeles/Unity-WebGL-UIToolkit-Exception

[hallow sequoia]

I'm looking forward to when you are able to resolve the issue. Thanks for the updates.

[vocal vapor]

Oh, I don't think it's a "I resolve" issue.
I'm pretty sure this is a legit Unity bug, that's been reported (one of the links in that github I posted).

[hallow sequoia]

If not "I resolve" at least "I find workaround"

[vocal vapor]

Yeah. My current workaround will be to just use LoadScene instead of LoadAsyncScene - which will require reworking some things, so I can quickly load a "nearly empty" scene so it loads as fast as possible. (Otherwise the music "freezes" when not Async). Then just turn things on once the new scene is loaded, and has its own music/sfx going.

[hallow sequoia]

e.g. do you get an "index out of range" if you wait 0.2 seconds after loading a scene to then access..?

[vocal vapor]

I've never seen the Index Out of Range error.
But my tests do have an example that delays loading/setup the UIDocument after the scene loads - and it still throws the Exception. So, not a solution.

[crude marsh]

what is easiest way to Fetch Session Storage Key value from WebGL build
currently facing few errors, any help is appreciated

[arctic rose]

Show the code and the error

[crude marsh]

manage to solve the issue using some GPT

getFromSessionStorage: function(str){
var keyName = UTF8ToString(str);
var returnStr = sessionStorage.getItem(keyName);
var bufferSize = lengthBytesUTF8(returnStr) + 1;
var buffer = _malloc(bufferSize);
stringToUTF8(returnStr, buffer, bufferSize);
return buffer;
}

as i am very new to JS this was code that was added to JSLIB inside plugin folder

this is implementation is for getting data for SessionStorage

Hi!
Can someone help figure out performance issues on iPhone? (WebGL project running in browser)
The issue seems to corelate with UI updates. Lately there have been some new features in our project and those added a couple new buttons to the main UI Document of the project. Since then the game glitches and crashes after click events, most commonly - those that call back to JS (the project has a web component too), but sometimes - even after clicking a button that just opens a UI window.
The problem occurs on iPhone XR (iOS 17, Chrome ver 120.0). Also checked on Google Pixel 3a (Android 12, Chrome v 120.0), but it ran smoothly there.

[elder warren]

Hi, I'm having a problem with UIToolkit input field when building for webgl and using full screen

the mobile keyboard is not showing up to type the input value

it works as intended if I'm not on full screen

is it a known issue or something? I can't find anything on the web about it

[elder warren]

The ui input field appears behind the canvas when on full screen

[elder warren]

another question, in the unity default template they have this code to detect if it's a mobile browser and make the canvas fit to the whole page, but somehow my ipad is not being considered a mobile device here

any idea on how to solve it?

this is my user agent on the ipad safari Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.6 Safari/605.1.15

hmm, it was a setting on ios, I wonder if it's the default value

[brazen niche]

Hey guys, I'm making a simple multiplayer project using WebGL and Mirror Networking. I want users to connect from a WebGL client in a browser to my server hosted on AWS. I've tested that my local WebGL and Unity builds can connect to the AWS instance IP but my WebGL build hosted on Unity cannot. Is there an obvious step I may have missed? Does Unity block multiplayer connections on their hosting?

Edit: In case someone else has a similar issue and comes across this. I found out the issue was that I was trying to use an insecure websocket connection from a secure HTTPS page. I can get around this either through setting Google Chrome's site settings to Allow insecure content, or through setting up a reverse proxy as described here: https://mirror-networking.gitbook.io/docs/manual/transports/websockets-transport/reverse-proxy

[glacial barn]

Well, if the canvas is in fullscreen it overlaps any other element on the html, that's how it works. Previously I think you could bypass that by setting the z-indez high in the other elements you wanted to overlap, but browser don't allow that anymore.
I think you could try to put the canvas and the other elements inside a div and then requestFullscreen on the div. And make the canvas width and height 100%, but not sure if that works

[elder warren]

in the end I decided to create my own keyboard, in the end I just need to input some number

what you suggested don't work

what kind of worked was to make the document.body request full screen

but it didn't work very well on my ipad

that's why I created my own keyboard

[high patrol]

unity's standalone webgl player can be problematic. Also WebGL does not allow sockets if you didn't know yet

Checking -- you can get a local webgl build running in your browser?

[plain shard]

@hazy mural unity is really shy about documenting the limitation with keyboards on mobile devices.

the following is impossible to ever create on mobile safari:

1. start with no native keyboard on screen in mobile safari
2. the user taps a canvas element anywhere in the page.
3. the native keyboard appears.

i understand that it is challenging to communicate to developers. they're going to get the takeaway that you cannot do text input on mobile safari with webgl. that is indeed true, you can't. it sounds like unity has decided it does not want to create a keyboard component, so that's 100% true.

[plain shard]

how familiar are you with CORS?

what role does your server hosted on AWS play?

[plain shard]

that's true, ipads are not considered mobile devices period. it's the default value.

it has been the case for at least 5 years

[elder warren]

I actually found a way to detect it's an ipad

[plain shard]

i mean of course it is possible

[elder warren]

using the number of touches

[plain shard]

to heuristically determine if something is an ipad, you can of course directly determine it has a touchscreen. but also, you should be using input system and pointers

then it doesn't really matter

[plain shard]

do you have a screenshot of your project? i am concerned you wrote "Chrome ver 120.0" on an iphone xr, because it is mobile safari in disguise

[turbid topaz]

I can make a screenshot, but I am honestly more interested in what you mean by mobile safari in disguise...
We have both safari and chrome installed on that iphone. chrome v120.0 and safari 17 (cause iOS 17)

[turbid topaz]

okay, i googled it and found some info. thanks for the pointer. didn't know that was the case... will keep digging for now

Greetings,

I'm experiencing a mixed content issue in my Unity WebGL project when hosted on a web server with HTTPS. I'm using the "Netcode for GameObjects" package to handle networking. While the project functions seamlessly on a local web server, attempting to deploy it to an HTTPS-enabled server triggers an error:

An insecure WebSocket connection may not be initiated from a page loaded over https

I'm aware that this indicates the need for a secure connection, but I've been unable to find specific instructions on how to achieve this within the "Netcode for GameObjects" package.

Has anyone else encountered this challenge? If so, how did you manage to overcome it?

And let me know it it belongs on the #archived-networking channel.

[fast linden]

hey

oops

wrong chat

[high patrol]

you can try connecting to the http: version

or you can try your hand at certificate signing

[broken plank]

I followed this guide for this but the issue still remains:

https://docs-multiplayer.unity3d.com/transport/current/secure-connection/

[high patrol]

does that give you an ssl self signed cert error?

[broken plank]

Thank you for your response. This is the error message now. The good thing is, it's trying to connect over wss. I guess there is something wrong with my certificate. I'll try with a new one to see if that's the problem.

Addressables does support WebGL. Local addressable assets are stored in the Application.streamingAssetsPath.

It sounds like you are running into InvalidKeyExceptions, did you build Addressables (in the Addressable Groups window toolbar > Build > New Build) before building the player?

I have it already built, but the errors I get say failed getting load state of fsb for "audio clip"

Is anyone planning to make games for webgpu? I mean specifically aiming for mobile&web market, and betting on the performance boost?

[high patrol]

#🌐┃web might need to be renamed to infer webgpu as well. I'm excited but feel it's going to be a few years before anything comes along to convince me to develop seriously for webgpu

Think unity's still waiting on specs from google on some of that stuff

[sweet oriole]

WebGPU’s specification has recently reached version 1.0, and active development is still ongoing. WebGPU is enabled by default today in Google Chrome on ChromeOS, Mac and Windows, and in Chrome Canary on Android.
https://forum.unity.com/threads/early-access-to-the-new-webgpu-backend-in-unity-2023-3.1516621/

[willow hamlet]

Does anyone know why the WebGL Wasm file is not caching in the browser, it keeps on redownloading again and again. My wasm file is 55 Meg and it's crazy for people to have to redownload each time.

[arctic rose]

Caching is (mostly) determined by the headers sent by the server

[sweet oriole]

Could host on Netlify and use Cloudflare to cut down on bandwidth costs. Ad providers can be regular HTML ad providers controlled with https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html. Adinplay is traditionally known to be relatively easy to get in and a bit more forgiving than starting straight with Google Ads (messing up and getting banned by Google is very not ideal).

[sweet oriole]

Make sure you don't have caching disabled in your browser debugging window! 😄

[lucid raptor]

Awesome. Thanks for the info.

[main beacon]

GUys why the hell the old cached webGl game is loading instead updated file 😭😭😭

So i need to generade New site for that!!!???

Is there any way to Fix that

[glass kite]

is there any workaround to WarpCursorPosition()? This unresolved Unity thread from last year points out that it doesn't seem to work in webGL ("From the docs : 'On desktop platforms (Windows, Mac, Linux, and UWP), you can move the mouse cursor via code.' Implying that it is not possible in WebGL via Code)
https://forum.unity.com/threads/forcing-mouse-position-in-webgl.1239901/

player movement in my game is tied directly to the mouse position, and WarpCursorPosition() was how I was fixing a glitch wherein the player would pause, move their mouse to the pause button, and then the player would "teleport" to the new position on screen. Unless I can fix that in webGL I'm worried I may have to scrap the entire prospect of uploading it through webGL, which would suck cause I really want recruiters to actually play this (and from what I've heard they rarely if ever bother to download anything)

[sweet oriole]

Changing file names is the most straightforward and reliable way to bust caches (of browsers and CDNs). Unity renames files for you if you enable "Name Files As Hashes" option in WebGL player settings.

[sweet oriole]

Apart from changing the input method to a virtual cursor based on mouse deltas rather than using the actual mouse position, you could force the user to move their mouse near their previous position before the game unpauses. Max cursor follow speed and ramping speed up from 0 on unpausing could also help.

[main beacon]

Thanks ill try

[glass kite]

mouse deltas is currently the main method I'm considering. might also do a slightly hackier method and store a vector to calculate the distance between the player position and the cursor position on Resume, then just calculate player pos as cursor pos + that vector. Thank you

Hi. I am having a Unity WebGL project and my prototype works on localhost. But after I released it to my server I cant connect via websocket. I can use a java client and connect to my websocket backend but I cant connect via WebGL. Is that a certificate issue maybe? Any advice on this? I have no iptables rules, dont use CORS and nginx rerouting should work fine as the ssl certificate seems to be working with my java client. Any tips are welcome. I asked in #development beginner chat but was told to ask here.

[brazen niche]

I am using Mirror's SimpleWebTransport which is supposed to work with WebGL (https://mirror-networking.gitbook.io/docs/manual/transports/websockets-transport)

[brazen niche]

Yes, it works fine locally using my Unity Editor as the Host and my browser as the client

[brazen niche]

I am not very familiar with CORS. There is a Windows build of the project on the AWS server which acts as the host (Windows build because the Editor fails when I tried to make a server build).

[brazen niche]

Mirror Networking uses port 7777 by default and I opened this port on AWS EC2 security rules and on Windows inside the AWS instance (My host). Maybe the issue is that the Unity WebGL game hosting (My client) would need to open port 7777 outbound but I have no way to control that?

Edit: the client does not need to open an outbound port, the issue was that I was trying to use an insecure websocket connection from a secure HTTPS page. I can get around this either through setting Google Chrome's site settings to Allow insecure content, or through setting up a reverse proxy as described here: https://mirror-networking.gitbook.io/docs/manual/transports/websockets-transport/reverse-proxy

[lucid pelican]

Hi all, I'm attempting to run an WebGL build of my project, but on 'Build and Run' the web browser launches and locks up. This means I can't open the javascript console to start debugging the issue, which is the Unity docs recommendation of how to proceed.

My file size is ~20mb, which seems reasonable? I can only assume performance is poor in other areas of my game.

Does anyone have another method of getting logs? Perhaps I should load this only a local IIS server and turn on all the logging options? Any help would be much appreciated.

Edit: I've tried Edge and Chrome, but both have the same issue. My game is published to Itch here, [REMOVED LINK]

[arctic rose]

Is that the version that locks up for you?

[lucid pelican]

I'm using 2022.2.20

[arctic rose]

I mean if you open the itch.io link yourself does it lock up, or does it only happen when you build & run from the editor?

[lucid pelican]

Ah, it happens in both cases, and I've sent the link to others who have experienced the same problem

[arctic rose]

It doesn't happen to me

I asked this in one of the coding channles but it fits hear aswell

in one my my projects I am using a the google sheets api. This uses google authentication api which uses Newtonsoft.Json. My project throws the provided error when build with webgl when ever a google sheets api call is made. Through research I have determined that this error is caused by AOT. following this guide: https://github.com/applejag/Newtonsoft.Json-for-Unity/wiki/Fix-AOT-using-link.xml I created a link.xml file and included it in my assets folder. here is the contents of my link file ```xml

Hi!
I was looking into a memory issue with a company project (WebGL) that was only occurring on iPhones and I think I might have stumbled into a memory leak on the WebKit side of things. Since I can't really visit random webGL projects from a company MacBook/iPhone, I would like to request some cooperation on double-checking that the issue is indeed webkit-related and maybe some help submitting an issue to the webkit bugzilla if it is indeed an issue on their part.

Now, a bit about why I think it is a WebKit issue as opposed to a memory leak in our app:

1. Taking multiple memory snapshots (after load, 5, 10, 15, 20 minutes later) using unity memory profiler from an autoconnected development build didn't indicate any memory leaks
2. The gradual memory usage increase (particularly - the part that Safari devtools labels as "Page") is observable both in our company Unity WebGL project, and 2 other company PlayCanvas projects
3. Noted memory usage increase doesn't seem to be related to the safari profiler itself, since the increase is not present on regular web-pages (html, css)

I will start a thread for this and attach 2 10-minute recordings from Safari devtools timelines to illustrate the issue. Any help checking / comfirming the issue would be greatly appreciated.

[cyan kraken]

hello, i have a simple very empty project with a single scene
i click on that button and it works as expected

but when i make a build it to webgl, the button no longer works
it does not even blink when i click on it, as if my mouse and keyboard inputs are not reaching the webgl
any idea what the issue might be, because it's working as expected in the editor

[charred briar]

I'd start by checking the browser console for error messages (f12)

And keeping in mind you need to click on the canvas first to make sure it's active.

[cyan kraken]

no error in console
so
I tried two things
1.
i added a TMP text in a corner and gave it input.mousePosition value
In WebGL build, the value stays fixed even if i move the mouse around, or click inside the canvas
2.
instead of using 2022.3.4f1, i switched to 2021.3.4f1, make the same setup, built, and this time the clicking worked

from the input, the mouse cursor seem stuck at bottom center of the canvas, and wont move no matter where i click
in 2022.3.4f1

[random talon]

I'm getting black screen after the initial Unity load if running a webgl app on mobile, is there any specific reason for that?

The are the 2 main warnings I get

[solar hound]

I making game in webgl and I update my game to my server but i have one issue with browser cookie, each time I made an update to server I have to clear cookies to see my new update how can i solve this issue, I want it to update immediately without need to clear cookies. please help!

[sweet oriole]

Browsers and CDNs like to cache everything, which is generally something you want. IMO the simplest way to update those caches is to rename your files, which Unity does automatically for your build output if you enable "Name Files As Hashes" in WebGL player settings.

[solar hound]

@sweet oriole I just change version code in index.html and it's works for me but in some pc i required to hard refresh in-order to get latest updates

[sweet oriole]

How exactly are you doing that?

[little panther]

Hi, I was facing difficulty when trying to implement Unity Relay on WebGl build it keeps giving me this message, please any guidance would be greatly appreciated

[sweet oriole]

Listening for connections would be for hosting, no? I imagine you would connect to the relay rather than wait for connections, but I don't know the details of Unity's networking stuff.

[little panther]

well what you are saying sounds about right but I was following unity's official documentation for cross-play

[little panther]

where you can work out the cross platform functionality using this, as it says "accept connections from both UDP and WebSocket"

[sweet oriole]

Is this specifically for relay or Unity Netcode in general? This sort of stuff is common if you have dedicated servers and need to be able to support multiple protocols. I don't think Relay would require this.

[little panther]

well to be specific, I am using Mirror, with Unity relay to perform Cross platform on PC and Webgl builds but since I am having difficulty understanding the issue and couldn't find much on google or any of forum I came here, I am am using a git repo which was a mix of both Mirror and Relay but it is not working for the Webgl build which is my biggest concern since Cross platfrom is a must for me.

[sweet oriole]

Pretty sure Mirror is already cross platform, hence the multiplexing transport component

[little panther]

this was also written before this

[sweet oriole]

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

A common use case for the Multiplex Transport is a server listening for both WebGL and mobile / desktop clients. Your WebGL clients can connect to the server using a Websocket Transport and your mobile or desktop clients can connect to the same server via TCP or UDP transports. You can configure any number of transports in the Multiplex Transport.

[little panther]

that I have tried but I am using relay in order to connect different players around the world without the need for a dedicated server which the unity relay has

[little panther]

I have done this but as I said that I need to be able to connect any area around the world and perform cross platform functionality on it. I used the Mirror's but when used with different PC and Webgl opened it wasn't connecting to the host

[sweet oriole]

There are some potential issues with something like Mirror in a peer to peer over relay type of configuration, namely with the host dropping out

Unless Mirror supports host migration now

[little panther]

I wasn't exactly facing the issue of host dropping more like client on the webgl build not being able to connect with the host on another pc build.

[sweet oriole]

Yea I was just mentioning it, since I'm not sure if you have thought what happens when the hosting client drops out. Hosts need to port forward if there isn't some other mechanism to do it for them or bypass it (like a relay).

[little panther]

do you mean when the host client drops out and causes the session to end ?

[sweet oriole]

Yes

[little panther]

no that bridge i'll cross later currently my biggest problem is Webgl not connecting with the host client

[little panther]

can you give me alternative to do this, which is doing cross platform, with Webgl (specially) with multiplayer functionality and be able to connect anywhere around the world.

[sweet oriole]

For a managed peer to peer over relay setup I would historically go for Photon PUN, but that has not been replaced with Photon Fusion. I imagine it also works well for this, but I haven't checked it out and I'm pretty sure it's a bit more complex (with better results tbf).

Nowadays my alternative is to just not build multiplayer games without dedicated servers, since there are very few types of games where that's actually the ideal solution 😄

[little panther]

but doesn't Unity Relay helps out with the dedicated server part problem ?

[sweet oriole]

Relays help to avoid the setup of forwarding ports for receiving connections, but it doesn't automatically make sure all state/data is kept on all clients so anyone can take over in case the "host" drops out.

I believe Photon Quantum demonstrates a more "hostless" peer to peer setup, but that's another can of worms in practice when you look at what Photon Quantum is doing.

[little panther]

I guess Photon Fusion it is. Thank you for the guidance.

[charred briar]

I'd second using photon, it's what we use

[random talon]

I'm trying to make a WebGL playable on mobile devices, previously I used WebGL 2.0 and it went ok on Androind but on Iphones the page crashed for some reasons.
Now I'm trying with using WebGL 1.0, it opens on both devices and it runs cause I can see the audio be on both phone I have blackscreen.
Do somebody know what could be the issue?

(I've used Unity 2022.3.11)

[main shale]

webrtc datachannel sdp peer realiable:disable than fast udp webgl , ice servers can also be configured for stun&turn connections

[main shale]

try to update or change the browser, some like firefox other chrome latest for webgl 2, and of course update device for gpu acceleration, in pc you can check it with about:gpu (however unset - intel bug can crashes vulcan but webgpu is fine)

[random talon]

thanks for the tips

Also does somebody knows if and how its possible to call methods of a unity webgl app from the browser console?

[charred briar]

Usually you'll write an intermediary between the two, so a common function you request through. https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html but yeah (check out: Calling Unity scripts functions from JavaScript)

so, via console, you could use Instance.SendMessage

[random talon]

with Instance you mean something called "unityInstance" or similar?

[charred briar]

  script.onload = () => {
    createUnityInstance(canvas, config, (progress) => {...}).then((unityInstance) => {
      myGameInstance = unityInstance;
      …```

It's the context in javascript when you create it

[random talon]

ok but this part should called in the site back/front end and not in the console right?

(sorry for newbie question but I'm not the guy who made the page so I'm trying to understand what is my part and what is not)

[ionic spire]

For my WebGL game I have an IPreprocessBuildWithReport class that generates some data about the build. It then saves this data as json to a build-info.json file under Assets/Resources. When I run the game in the editor, I load the file and display some info on the start screen (build time stamp, git hash, etc.).

I'm loading the json like this (during runtime):
var json = Resources.Load<TextAsset>("build-info").text;

And saving it like this (this runs when making the build):
File.WriteAllText("absolute/path/to/Assets/Resources/build-info.json", json);

My problem is that this does not appear to work at all in a build (itch or local). It works fine in the editor. Any idea what I am doing wrong? I found this documentation about webgl resources but I don't think it is relevant: https://docs.unity3d.com/Manual/webgl-embeddedresources.html

EDIT: I'm going to run with a scriptable object version (just a regular .asset that I update before a build) because that seems to work.

[high patrol]

I don't think you're allowed to just access any file willy nilly when contained in the browser

File.WriteAllText("absolute/path/to/build-info.json", json); might need to be changed to point to someplace you know you have access to, like Lgk said with playerprefs maybe

Are you sure the UIElements label is failing in the constructor? Or is it failing somewhere else?

[ionic spire]

This runs at build time, not at runtime in the browser

[high patrol]

oh derp that's right. Well the path you're writing to may be restricted. Where does it path to?

[ionic spire]

Assets/Resources

[high patrol]

You are not allowed to write into the resources folder. Use PlayerPrefs or Application. persistentDataPath

[ionic spire]

That isn't true. You can write whatever you want wherever you want in the editor. Regardless, I was able to work around this issue (as explained in my original comment)

[high patrol]

Interesting, I ran some tests and you're right. You may need to verify that the path is valid though

[weary wasp]

Hi guys, whats the best way to capture audio and vidoe in a WebGL build? I want to be able to output an mp4 file with audio and video, so far I've used a couple assets from the asset store that only record video well but not good for producing an mp4 with audio as well.

[solar hound]

How can i setup google signIn in unity webgl build, there are documentataion about android and ios with unity but not for web+unity

[random talon]

Please let me know 🙏 I haven't found any guide about this

[weary wasp]

You can do a regular web signin page that then loads the WebGL page after sign in is complete

[random talon]

  script.onload = () => {
    createUnityInstance(canvas, config, (progress) => {...}).then((unityInstance) => {
      myGameInstance = unityInstance;
      …```
Can somebody help me implement this in the index.html?

[random talon]

nvm I've probably solved, but wonder if there is a way to somehow automatically include it in the build to avoid having to edit the index.html everytime after I do a build

[charred briar]

Sorry busy day, that's the javascript side. When the Unity template creates the Unity instance it should have a reference to it. That shows you how to call some methods into Unity from the Javascript side, which could be done via console. I don't have much interest in web development however, so I can't help much beyond that I'm afraid

But yes, you can and should create your own WebGL templates and use those

That way all your classes don't have Unity in the naming, and a bunch of Unity logos on your loaders and throughout.

[random talon]

Yeah I already use the "minimal" one

[charred briar]

It's tricky and be cautious, a lot of those will use ffmpeg which won't work in an actual browser. Test often

[random talon]

I'll try to read documentation about custom templates

[charred briar]

They are very helpful

You can basically copy their existing templates and modify them. But the infos in the docs and pretty decent on the subject

[random talon]

btw I'm happy that I made it work by myself (maybe is easy af but I have poor knowledge outside the Unity environment)

[charred briar]

Awesome!

[weary wasp]

Yes none of them work very well. An alternative is to record the canvas object that the game instance renders to but then again there is the issue of audio. Is there a better way that I might be missing?

[clear grotto]

what do you use this for 🤔? atm im using unitywebrequest to call the web server and parse the data to use in my slots game but i was wondering if the way you did it would be an alternative for me

[random talon]

I'm using a webview to integrate a webgl game inside a mobile app (yes sounds weird but its the quickest way to port a game from the webgl pc version and Iin this way can keep developing only 1 build for all platforms) and looks like the browser console its the only way I have to comminate to unity there

[main shale]

what +additive size gets the webgl project if you use the webview, and what specific url/github/asset can you link it?
(advantage could be that also the native control keys / touch and android / iphone / keyboard could show of a filed focus?)

[random talon]

sorry could u explain better?

[main shale]

what asset / code you used for webgl webview at your example

[random talon]

oh thats unknown to me, another figure is doing that

[main shale]

here you said you use webview in webgl game

[random talon]

not on pc version tho, only on mobile since I use an mobile app and then the webgl inside

and in that case another guys is doing the app while I'm prepping the webgl to deliver to him

[random talon]

I'm having issue when trying to load a webgl app on mobiles, the app load (I can hear the audio) but I get a blackscreen on video
I've excluded all the "harmless errors" and I came down to this one:
GL_INVALID_FRAMEBUFFER_OPERATION: Framebuffer is incomplete: Attachment has zero size.
can somebody help?

Also I've noticed that on another site where the WebGL app is embedded it has no blackscreen error, so can I assume that its an issue on how the app got implemented in the website?

[solar hound]

Hi, I'm trying to impletment signin with google into my webgl build, this is a documentation for web but its not for Unity https://developers.google.com/identity/sign-in/web/sign-in, how can i do this with unity using c#.

[little panther]

I was having difficulty implementing the stateAuthority funtionality in Photon Fusion 1, for a VR network object while I was doing that I realized why isn't a lot of the things in fusion not automated and rather have to be done manually? or is there any easier plug and play method?

[charred briar]

Not sure #🌐┃web is the best place to ask that. #archived-networking seems much more appropriate.

[ionic spire]

Check out this doc:
https://docs.unity3d.com/Manual/webgl-interactingwithbrowserscripting.html

You likely need to call some javascript function from Unity. Unity creates some HTML files when exporting a webgl build so these functions would probably live there.

[eager grove]

I have a 3D project that I want to export to WebGL. In the current build it works on computers and android phones. The only iphone it works on are 15/15 max. Can anybody help me problem solve? The goal is to get a build that works across computer and mobile. I'll make it worth your while. Let me know, Thanks!

[sullen tiger]

Any ideas? Im using Unity 2020.3.26f1

[sullen tiger]

Using the newest Unity Editor solved this issue 🙂

[charred briar]

I'd definitely start by posting the problem you are seeing on other devices, unity version, errors etc. Mobile webgl isn't supported well by unity.

[eager grove]

Thank you for the reply! That’s what I’m hearing but we’re in too deep at this point. I’ve tested various devices. Seems to be fine on computer and android. On iPhone 14 and lower the load bar appears but when it finishes you are met with a white screen. It works on iPhone 15 and 15 max though. Version of unity is 23.2 I believe.

If anybody thinks they can problem solve it let me know I’ll make it worth your while

[charred briar]

I'd start by looking at the device / console logs. But I'd suggest posting the exact unity version, the errors in the console itself, etc. It's possible it's either running out of memory, or something simple like disabling auto graphics. But the log will take you there. Without the log or profiling it's just random guessing.

On the second topic @eager grove you need to go to the forums for hiring etc. Links to above.

[charred briar]

I'd try and make sure you have the latest version of unity. I believe 2023.x is when they began adding mobile support. I'd try disabling auto graphics and forcing it to a lower opengl just as a test step. It sounds to me like a mobile css issue though... I'd suggest trying to run Chrome or Firefox in mobile layout and see if that causes the same problem. If so, at least now you can use the inspector and see what's happening with the html - checking the canvas exists etc.

In those cases it's also worthwhile to do a micro test build (empty unity project) just to make sure it's not a issue with the builds - and without needing to wait for long build periods.

If you can narrow it down to a CSS issue, then you can create or edit the custom templates 🙂

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

https://docs.unity3d.com/Manual/GraphicsAPIs.html

[charred briar]

I'd also get someone with android to test it as well. I remember seeing someone on here having a lot of memory issues with webgl on Apple devices, and I suspect that might be what you are running into. Assuming it isn't just a graphics incompatibility issue.

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

[eager grove]

Here’s the console log from an Iphone8 on Safari. Unity version 2023.1

[eager grove]

Yeah I assume this is the problem. Tested on 3+ android devices and they’ve all been fine

[eager grove]

Thank you for the info. I posted up there early today as well

[charred briar]

Ah those shader errors could very well be the culprit. It might actually be the autographics setting

Without the shader working it won't be able to draw things. It looks like it's using HDRP which I believe just won't work on webgl for mobile. But I'd force it to use OpenGL 2.0 (right now it's failing with 3.0). But I'm doubtful about HDRP on mobile over webgl 😦

https://forum.unity.com/threads/hdrp-build-on-webgl-platform.748601/

[eager grove]

This is very useful info thank you!! I will dive deeper

[random talon]

I kinda solved, since even a blank scene would get me a black screen I then tried a fresh new project and that same blank scene worked so the issue was within my project.
I basically exported all my scenes in a new project and the issue was solved, even using the same Unity version.
Maybe I had some bad unused asset that somehow still generated issues.
Now both android and iOs works with WebGL 2.0, the only thing I have to change exclusively for iphones is the color space, somehow i still get blackscreen when iphones open a Linear colorspace app, so for that instance I switch to gamma which is a bit uglier but a fair compromise

In that case I wonder if therese a way to automate a build outputting 3 versions:
-Linear colorspace and DXT texture compression (PC)
-Linear colorspace and ATSC texture compression (Android + Tablets)
-Gamma colorspace and ATSC texture compression (iOs)

[glass kite]

will platform dependant compilation still correctly identify mac vs windows if both builds are running in webgl?

[stoic scroll]

you're building you game for WebGL, not for Windows or macOS

so I would expect the answer to be no

[glass kite]

hm damn

[stoic scroll]

wait, HDRP works on WebGL at all? that's news to me..

i thought you were missing compute shaders there

[charred briar]

I'm not sure to be honest, i didn't think so either, but it looks like they are using it on mobile with most platforms successfully.

[glass kite]

I'm trying to adjust my mouse sensitivity and I'm noticing the ranges are wildly different depending on whether it's run from mac vs windows

that might just be editor dependant and I'm curently building it to run in webgl to check but I was hoping I might be able to define separate ranges for each platform

[stoic scroll]

Definitely check how the build performs.

[charred briar]

I figure they may have also imported it by accident but aren't using it.

[stoic scroll]

I know that scroll wheel input is often messed up on macOS when people ignore the magnitude of the scrolling

the trackpad on a macbook sends lots of tiny scroll events

but that's unrelated to mouse input

I need to call a JS function inside the index.html but I read that application.externalcall is deprecated

what is the current alternative?

[arctic rose]

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

[random talon]

I made the jslib now I only this part of syntax

[arctic rose]

That's where you call the function you want

[random talon]

so I have to do this : Android.functionName(paramter) can I just putt it where the ??? are?

[arctic rose]

Yes, that's where you put the JS code that you want to run

[random talon]

ok thanks

oh, one thing

I have a block of code that want to include in the index.html (its purpose is to create a unityInstance)
Is there a way to somehow automatically include it in every build? Cause for now I have to manually write it inside the index everytime I do a new buildl

[arctic rose]

Put all that in the jslib

[random talon]

oh that too?

and how can I execute it on start?

[arctic rose]

Oh right, that's not the function you're calling from the jslib. Forget that, it won't work then

[random talon]

so I'll have to manually put it inside each build...

[arctic rose]

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

[random talon]

Yeah I've read that plan B would be to make a template for seems a bit too complicated...

[arctic rose]

How is that complicated?

You copy the default template and add your script there, which is exactly what you've been doing so far after every build

[random talon]

ok then I'll try

[random talon]

BRUH that was dead simple

Idk why I got scared of that

Now I'm using Minimal, next step is to take standard as bade and cut everything except the loading bar

I'm planning to develop a web game but a critical part of this project is the accessibility with the WCAG 2.2 guidelines. Anyone had test that and know if Unity is a good game engine for this purpose? Because I found that there are alredy some Unity addons for that purpouse but I don't know how good they work. I mean if I export it to web using HTML5 all the buttons and object will be accesible with keyboard, screenreaders can obtain the text from the buttons and menus, the screenreader works properly and all this. At the moment I'm just comparing different game engines and I think Unity is my best option. Thanks beforehand

Issue resolved. Solution: I needed to use the FQDN to connect (example.com) rather than the IP (123.45.67).

Hey guys, I'm making a simple multiplayer project using WebGL and Mirror Networking. I want users to connect from a WebGL client in a browser to my Windows server hosted on AWS. I was able to connect but I needed to allow insecure connections in chrome since there wasn't an SSL cert so I registered a domain, set up a reverse proxy using IIS on the server, and an SSL cert on the server following the mirror guide: https://mirror-networking.gitbook.io/docs/manual/transports/websockets-transport/reverse-proxy/windows/iis. On AWS I set the domain to redirect to the IP of the EC2 server. When I enter the domain in the browser it will load the WebGL game client. When I use the EC2 instance IP to connect to the server (hosted using a Windows build) it doesn't connect. Usually an incorrect IP will say "connecting..." for a while but this will instantly stop trying. I have also tried with the ports, with the domain name etc and those say "connecting..." for a while and then nothing happens. Does anyone know what may be wrong or which IP I am supposed to use to connect?

The Client transport is set to port 7777 and the server to 27777.
This is my web.config file:

I'm not familiar with web as I'm usually a mobile / desktop dev. Do you have any advice on how I can move forward with this?

[charred briar]

Hmm looks like it's a Google Cloud bucket

</Error>```

I've never seen our itch pages for our games generate that error before, but if it is an itch redirect of sorts, it looks like an itch bug to me

[serene orbit]

One thing that may be a clue is that it works on desktop safari but not on mobile.

[charred briar]

Yeah it'll work in some browsers, it's the browser blocking it, trying to stop you from getting a fishing site pretending to be itch.

[serene orbit]

Right that makes sense.

[charred briar]

Although in this case it looks like it is itch they just didn't configure something

It looks like where they dump your html files to once you upload a build

[serene orbit]

I was thinking it might be an itch issue so I was going to try to upload to to github pages but my LFS is broken lmao

batch response lfs denied

Got any other sites like itch I can try by any chance?

[charred briar]

https://itch.io/t/3230296/webgl-game-works-great-locally-but-continually-fails-lags-on-itchio

[serene orbit]

I might just ask my client if I can get access to his web server to upload the build instead of using itch. I'm only using itch to test.

Could single out the issue if its only an itch thing

The app is using firebase and I had to manually add some code to the index.html, im not sure if that can cause hte issue.

But it's just firebase generated auth stuff

This all works in browser on desktop, so i dont see how it could

[charred briar]

I'm 95% sure it's itch.io

If you have your own anything though, even dedicated WordPress, you can just ftp it up to test.

Unity also has its own web hosting I think now for web builds

https://www.reddit.com/r/Unity3D/comments/mfwymm/free_unity_webgl_hosting/

[late ocean]

What

😐

[serene orbit]

Thanks I'll give that a try.

To your knowledge though are these things I can change or modify in the editor at all?

itch needs to zip and can cointain max 1000 files, keep loading by demand and not atlas scpite maps, simmer got to mutch ads trackings speed gone to low - one ads in side would be accepted but not during all loads, addressables gzip, has it any server side scripts for leaderboard or save gamestand and connect users.

[charred briar]

I didn't ask about that

[main shale]

dark mode / light mode feature, i see there, and 13 pages of games can be sorted by category on search. full screen, but embeded can be problematic if some devs dont like to see game moved. search by dev also there, players can not rate without some logins, if game fineshed it schould be able by any player to be rated. stars 50/100, compare more and show us info.

[main shale]

vr just for info to others, mozilla describes that the input controller can be keyboard, mouse, but does it also work webgl if using a gampad controller ( xbox, ps2 controller, ps3, logitech, bluetoth joystick)

[obsidian cliff]

What are you talking about?

[main shale]

web xr / vr glasses with a controller instead slow hand detect, using on dark the ps5 controller

[obsidian cliff]

I'm still can't figure what you are talking about

[main shale]

build for xr

your title: New getting started guide for WebXR and Unity (+XR Interaction Toolkit). All you need to make it work in a game jam.

but with ps4 controller ( trust me keyboard and mouse would work see mozilla webxr js )

[obsidian cliff]

How Mozilla relates to this video or to input?

[main shale]

navigation

[obsidian cliff]

And how ps4 controller is related?

I'm confused

[main shale]

lets see here, there are a lot of input options, but why not use the standard of gamepads, https://developer.mozilla.org/en-US/docs/Web/API/WebXR_Device_API/Inputs

[obsidian cliff]

I'm still not getting what you are trying to say.

[main shale]

just simple using a bluetoth gamepad controller and at same way VR as double screen big monitors

[obsidian cliff]

I have no idea what you are talking about.
The video was about using Unity with WebXR.
On what part of the video are you commenting?

[main shale]

Add WebXR Input Profiles ( controller types was q )

[obsidian cliff]

Ok.
What about this part?

[main shale]

package manager /if sup input system but thats diffrent, continue your way.

[obsidian cliff]

"sup"?

[main shale]

if supported input system to work with webxr or any kind of VR (in relation gamepad)

[obsidian cliff]

Are you asking?

The Immersive Group of W3C created a database of 3D models and description profiles of XR controllers.

As part of the WebXR API, there's a list of profile names to the connected XR input source.

So when in XR session in WebXR, developers can read this value, check the XR controllers database, and load the relevant model.

This is the repo for the database
https://github.com/immersive-web/webxr-input-profiles
This is the repo for the Unity loader
https://github.com/De-Panther/webxr-input-profiles-loader

I don't get how mouse/keyboard or PS2/PS3 controller is related here?

[main shale]

Using keyboard and mouse events , in doc they show keyboard WASD
document.addEventListener("keydown", (event) => {
switch (event.key) {
case "a": case "A": avatar.posDelta.x -= ACCEL_X; break;
case "d": case "D": avatar.posDelta.x += ACCEL_X; break;
case "w": case "W": avatar.posDelta.y += ACCEL_Y; break;
case "s": case "S": avatar.posDelta.y -= ACCEL_Y; break;
default: break; }}); // https://developer.mozilla.org/en-US/docs/Web/API/DOMPoint

[obsidian cliff]

What is this code? How is it related to this?
And it's not in the link you provided.

[main shale]

https://developer.mozilla.org/en-US/docs/Web/API/WebXR_Device_API/Inputs //but only the part of keyboard is listed not mouse at Using keyboard and mouse events

[obsidian cliff]

This is a Web JavaScript guide for WebXR.
The code sample is from a part that show to JavaScript devs how to use keyboard events.

How is it related to the video or our talk?
What are you trying to say or ask?

[main shale]

the 3 axis of vr could be forwarded by any axis in js, mouse wheel , mouse x,y, question is if first is giong to work with mouse than try with game controller <-- thats the point of interess

[obsidian cliff]

Are you asking if you can use keyboard or mouse for input while in XR mode in WebXR?

[main shale]

not the virtual keyaords, but i mean thre real keyboard, real game pad

[obsidian cliff]

Are you asking if you can use physical keyboard or mouse for input while in XR mode in WebXR?

[main shale]

yes i am asking (good&fast work of) phyical input controller, like keyboard, mouse, gamepad

[obsidian cliff]

Ok, I think that now I got what you tried to ask.

It should work. Depends on the device and browser.

[main shale]

physical bluetooth input controller: first of all keyboard, mouse than gamepad controller ps3 (any brands)

[obsidian cliff]

Developers made "virtual desktop" like experiences using WebXR on Quest.

But they didn't use Unity.

The way Unity on web works, should support it.
But I didn't test it.

[main shale]

if you can take bluetoth game controller, i mean they can fly fight simulators, test in VR

[obsidian cliff]

Detecting different gamepad types depends on the Operating System and the browser.
If it's detected in the browser not in XR mode, it should be detected in XR mode as well.

But I didn't try it.

[main shale]

let me explain the
left game stick position |__ and the / trigger on side for one hand to config, press on stick

[charred briar]

They were positing some kind of chatgpt stuff in channels, including #1157336089242112090 and seemed to be asking people for $5m. Just take it their advise with a grain of salt.

[main shale]

we know some moderators, if they want to nerve, than they ask are you ai talking english, but dont get disturbt focus

how they think there is so mutch of millions of $ i dont really know, even not hope ai to be a money maker machine

[obsidian cliff]

Non XR physical devices don't have their Pose in XR.
The sample you mentioned controlled an avatar like it would control it in non-XR

[main shale]

do you mean with ir kinect 2, rig tracking, motion capture, but that are all slow input dev.

what i read is web xr has its own input, but like in that code other inputs can replace and forward, reconfigured.

[obsidian cliff]

Looks to me like non English speaker, who try to copy/paste from google translate.

[obsidian cliff]

What it says there, that while in WebXR you should still be able to get input from non-XR devices.

[charred briar]

Maybe, here is the thread I was talking about: #1199381888461176914 message just saying take the convo with a grain of salt

[obsidian cliff]

Yes, looked the same there as well

[charred briar]

Well, feel free to ignore my advice then

It's not pertinent to the convo

[main shale]

its ok some people are thinking techinical other social, view perspectives but all do xp

[obsidian cliff]

Not ignoring. But thanks 🙂
(I was thinking to stop reply to them, but from time to time they do manage to explain what they are talking about)

[main shale]

we are in topic of input controller, please, let us know is a physical bluetoth game controller supported , for VR webxr

[charred briar]

I'm going to heart instead of thumbsup, because I appreciate you trying and being patient with them, and a thumbs up seems dismissive without being supportive

[obsidian cliff]

I answered already.

It depends on the Operating System, the devices, and the browser.
It won't detect the Pose of those devices, but it should get the usual input of those devices.

You'll have to try and see if the devices you want to use works.

[main shale]

it has not to be answered now, it can be add in this channel if you get some news about it, thx.

[obsidian cliff]

It's not something that I'm going to try.
But if you'll try, you are welcome to update us what devices you used and if it worked.

[brave tide]

hello, all creative and beautiful minds across the globe. Today is my 1st day, here.

i have been trying to make a playble ads, and i thought that i will do it with the help of WebGL build. but it is giving a lot of file and i need a single html file. now after spending a lot of time, i am thinking is it even possible to make a playble ad directly from unity/ webgl.

[charred briar]

You need a special version of unity.
https://www.reddit.com/r/unity/comments/18z1lmx/can_i_make_playable_ads_with_unity/

Personally I wouldn't use Unity for it

[brave tide]

sir, what tool you use.

i have also got this time with luna. is it good? and i want to know your method.

[sweet oriole]

Project Tiny has been discontinued.

[sweet oriole]

I would start looking at native browser game engines/frameworks. Playable ads/instant games tend to also have pretty strict download size and memory requirements which can be hard to hit using engines that haven't been targeting these things for a long time.
Web Game Engines & Libraries: https://www.webgamedev.com/engines-libraries/web-game-engines-libraries
Cocos Creator and Defold may also be better options.

[clear grotto]

i was wondering if some of you can share how much memory your webgl game uses in the browser and if you had to tweak the build to lower it (mine is currently at 141mb and it feels like a lot)

[vocal vapor]

Not sure which channel best fits this question, but it's a WebGL issue so guessed here?

https://issuetracker.unity3d.com/issues/indexoutofrangeexception-in-uielements-dot-layout-dot-layoutmanager-dot-destroynode-when-changing-uxmls

Is there any alpha download or something I can download with this fix? Or, does anyone have any idea how long it might take before I can try using it?
[I don't fully understand the ticket status]

This issue is severely slowing me down, trying to build ridiculously hacky work-arounds that barely work; so, I am very eager to finally have it.

[charred briar]

I wouldn't to be honest, I'm not interested in ads. But if i absolutely had to, I'd try phaser or aframe first

Anything small and lightweight. You'd need to check each one to find one with official support however

[astral wave]

our project use 350~mb RAM, which causes crashes on iOS older models. anything that is above 300 mb is bad if you aim for mobile platforms. so 140mb is pretty good if you will not increase memory usage in the future.

[clear grotto]

i see.. my game is a 2d slot machine type game and is 1 scene atm. my assets are all PNGs and i notice they are much larger in unity than they are on the system and im going to compress them further to lower the build size and test memory again

as far as comparison. when i go look at games built on unity on itch.io and snapshot the memory its only 12mb 🤔...

[astral wave]

Most likely you have textures that takes most of your memory. Or maybe you using URP and leave too many possible quality settings (low, medium, high) or features you don't need. I strongly suggest to use https://docs.unity3d.com/Packages/com.unity.memoryprofiler@1.0/manual/index.html
which will give you detailed informationabout your memory usage. Have in mind that profiling should be done on build version and not editor, as differences are very big. Also textures and images compression format is very important, as in game you DO NOT sure png. Png will be transformed to format that rendering understand. And mobile and pc uses different formats, at here you can find your png that is 1024x1024 and size of 17 Kb will actually be converted into RGB 32 and will eat 4mb of memory (while compressed with correct compression uses 1mb). More about it here (https://docs.unity3d.com/Manual/class-TextureImporterOverride.html). In most cases textures size and format is main culprits for bug memory usage

[clear grotto]

thanks alot for this info i will spend the rest of the day improving my textures as much as possible

i had downloaded the memory profiler yesterday but was running it in editor mode and dismissed it when i saw 2gb memory 😅 . didn't know u can do it in build version that will definitely help

[astral wave]

there are guide how to do it. The easiest way is to in build settings set it it developer and select autoconnect profiler. Then press Build and Run. this way it will automaticly connect your profiler to Webgl project running on browser.

[solar hound]

Hi Friends, I have set custom mouse pointer design in unity webgl and in my page i use a image picker so whenever I open it and then when its close the mouse pointer come back into its normal design, so basically i want to keep my custom mouse pointer when i come bake to unity webgl

[astral wave]

Most likely you need to return focus to your WebGL html window. If you press left mouse click on the application it changes to custom one right? if yes you will need to handle that in JS

[solar hound]

Another issue with a cursor bracket which is not visible when the inputfield(legacy) is selected

this issue only occur on chrome

[astral wave]

what unity version are you using? and how you changing it? just by setting it in Player settings? Are you using any webgl input assets like https://github.com/kou-yeung/WebGLInput ?

[cinder creek]

Hey guys, how is the build process? Has it been improved or it still takes forever to build a 20 mb project?

Paused on Unity for a while and deciding to come back to work on project...

[random talon]

Can somebody help me figuring out how to call a method from the index.html to unity script?

I've made a method inside the index.html that detects the device when the WebGL app is loading,
after that I need to communicate it to Unity by calling a method called _SetPlatform(int) how can I reach it?

[arctic rose]

Have Unity call that function instead

[random talon]

wym?

[arctic rose]

I mean have Unity call that function instead

[random talon]

does it detect all devices without issues?

[arctic rose]

I don't see how that's related to the question

[random talon]

Im not understanding your solution

[arctic rose]

Make a jslib function that calls InvokePlatformSpecificMethod, call that function from Unity when the game has loaded

If you need this function to run before the Unity game has loaded, store the result to a variable and retrieve it with a jslib function when you need it

[random talon]

Ok now it makes sense, im ok with calling it once unity finished loading, the only thing I miss is how to get a var in return after having called that method

[arctic rose]

return 3 instead of setPlatform(3) and so on. Define the extern method as returning int

[random talon]

So assuming I call this method inside a .jslib at start, is it supposed to work or do I miss something?

[arctic rose]

Well depends how you call it

[random talon]

Like this?

I know that int isnt going anywhere, made it just to show it

[arctic rose]

yup, that should do it

as long as platform is defined somewhere, I'm not sure how strict the jslib file is

[random talon]

oh it works! thanks for the suggestion!

[charred briar]

I've never had unity take forever for a 20mb project, I'd suspect the problem is the project.

[cinder creek]

I just took 20 minutes to build a 20 mb web build...
