Unity Webgl Extreme Race (2024)

FAQs

Is Unity WebGL deprecated? ›

In Unity 2022.1, the WebGL 1 graphics API is no longer included in the Auto Graphics API setting. If you need to add support for WebGL 1 to your project, open the Player Settings and under Player → Other Settings, uncheck the Auto Graphics API option and explicitly add “WebGL 1 (Deprecated)” to the Graphics API list.

It supports browsers providing the following conditions are true: The browser is WebGL 2 capable. Note: Unity no longer provides support for WebGL 1 in builds created with the Auto Graphics API option. For more details, see WebGL 1 deprecation.

Enable Data caching so that Unity caches your contents asset data on the user's machine. Data caching can make the application run faster.

That 2GB limit is imposed by the browser for each tab, and this includes memory for everything on that tab - cache, images, html, javascript, the unity app and so on.

WebGL uses GLSL (OpenGL Shading Language) whereas WebGPU uses WGSL (WebGPU Shading Language), though you can argue that these map to each other somewhat directly. Debuggability - WebGPU has richer error handling and better error messages.

WebGPU is a JavaScript API provided by a web browser that enables webpage scripts to efficiently utilize a device's graphics processing unit (GPU). This is achieved with the underlying Vulkan, Metal, or Direct3D 12 system APIs. On relevant devices, WebGPU is intended to supersede the older WebGL standard.

Unity web player has been discontinued for quite a long time now. There is absolutely no reason to waste your time developing for an obsolete platform.

unity is introducing slowly more and more webgpu support, but again you are at the mercy of browsers and the like…

WebGL builds use IL2CPP so you experience the kind of compilation a C++ developer would. It's normal, unfortunately. Fortunately, incremental builds will be faster. You also have the option to optimize for build time rather than runtime speed or size, which helps a bit.

A common way to optimize WebGL performance is to reduce the amount of polygons by baking a normal map from a high-poly model to a low-poly model. However, normal maps may produce visible artifacts due to the limited precision of a 8 bit image.

Why is Unity so slow to load? ›

Unity mostly loads assets when they are used in the editor and assets are generally speaking only unloaded every once in a while when an asset garbage collection is running. This means that running an operation for the first time is generally speaking slower than when you repeat it.

It may still work, especially on high-end devices, but many current devices are not powerful enough and don't have enough memory to support Unity WebGL content well. For this reason, Unity WebGL shows a warning message when trying to load content on mobile browsers (which can be disabled if needed).

Compression Format

Brotli compression offers the best compression ratios. Brotli compressed files are smaller than gzip, but take a longer time to compress, which increases your iteration times on release builds. Chrome and Firefox only natively support Brotli compression over HTTPS.

Technical overview. To run in WebGL, all code needs to be JavaScript. We use the emscripten compiler toolchain to cross-compile the Unity runtime code (written in C and C++) into asm. js JavaScript.

It depends on browsers actively stripping OpenGL support from their builds. As long as a fraction of the web still uses WebGL functionality it will be around as an API, just used less. Chrome and Safari both implement WebGL using the ANGLE library on all platforms. Firefox has its own WebGL implementation library.

UNet is a deprecated solution that is no longer supported after Unity 2022.2. Unity Transport Package is the default transport for Netcode for GameObjects.

Unity web player has been discontinued for quite a long time now. There is absolutely no reason to waste your time developing for an obsolete platform.

Unity 2020.3 reached end of life in mid 2023. It is now approaching mid 2024. since 2020. x has been out of LTS for so long now we have removed those versions according to the published deprecation schedule, and since nobody asked for an exception to be made we continued with the plan as published.
