Build and Run

A Unity WebGL template is a collection of HTML, CSS, and JavaScript files that surround the WebGL canvas that renders the game. LoL provides a Unity WebGL template that allows a game to communicate with the LoL platform.

When building:

1. File -> Build Settings

2. Select WebGL as the platform

3. Open Player Settings for WebGL -> Resolution and Presentation

   • Select the lol-template WebGL template

   • Ensure that the Run in Background checkbox is NOT checked (see Concept->Pause + Resume for more info)

4. If using Unity 2018

   • Open Player Settings for WebGL > Publishing Settings > Linker Target

   • Ensure that Linker Target is set to Both. This will produce a WebAssembly build in addition to the fallback asm.js format for browsers that do not support WebAssembly. (see the Unity User Manual for more information).

   • Note that Unity 2019 no longer supports the asm.js fallback, so there is no longer an option to set the Linker Target.

• For SDK 5.3 Brotli and Gzip Compressing are now allowed, but the uncompressed build still needs to be under 30MB
