Support splitted wasm and data files in WebGL builds for Unity 2021.3.16f1
Raw
readme.md

Setup

  1. Split wasm and data files

Example in bash:

 split -b 1990k -d game.data.unityweb game.data.unityweb.
  1. Replace config values in index.html

Instead existed url single strings

var config = {
//  ...
   		dataUrl: "game.data.unityweb",
   		codeUrl: "game.wasm.unityweb",
//  ...
   	};

use array of new paths

 var config = {
//  ...
   		dataUrl: ["game.data.unityweb.00", "game.data.unityweb.01" /*, ...  */],
   		codeUrl: ["game.wasm.unityweb.00", "game.wasm.unityweb.01" /*, ...  */],
//  ...
   	};
  1. Replace your *.loader.js on WebGL.loader.js from this gist

Required settings

Comporession Format: Gzip
DataCaching: true

How to rebuild for other Unity version

Require patch UnityLoader.js template in WebGLSupport

Patch created for Unity 2021.3.32f

Required enabled Decompression Fallback in Project Settings / Player / Publishing Settings

Apply split_support.patch

This patch created from diff between UnityLoader_2021.3.32_original.js and UnityLoader_2021.3.32_patched.js

cd %UNITY_PATH%\Editor\Data\PlaybackEngines\WebGLSupport\BuildTools\UnityLoader
# backup original file
cp UnityLoader.js UnityLoader.js.bak 

patch -p1 UnityLoader.js split_support.patch

After patch UnityLoader.js you can build WebGL

Extra

For automatic split files and change index.html may use this python script: prepare.py

python prepare.py %PATH_TO_WEBGL_BUILD%

For Windows can use wrapper with drag-and-drop support:

prepare.bat

python prepare.py %*

If I understand, this splits the build file generated by Unity in two separate files? Can this be used to optimize itch.io builds?

It splits the build files into parts with a size limited to a certain maximum. It makes sense to use this only if there is a restriction on the maximum size of a single file. The overall size of the build does not change.

I keep getting directory not found error. Maybe I am stupid but a more detailed guide on how to use this would be really great as right now I barely understand the requirements and/or what's needed.
