Detect mobile client in webgl

Question

I need to detect whether the user is running a webgl app in a mobile browser or on a desktop/laptop browser. Is this possible to detect using the Unity API, or you need to do some HTML hack?

Found the answer. In case anyone else needs it:

in assets/plugins/webgl/MyPlugin.jslib

 var MyPlugin = {
     IsMobile: function()
     {
         return UnityLoader.SystemInfo.mobile;
     }
 };
 
 mergeInto(LibraryManager.library, MyPlugin);

Then from unity:

     [DllImport("__Internal")]
     private static extern bool IsMobile();
 
     public bool isMobile()
     {
         #if !UNITY_EDITOR && UNITY_WEBGL
             return IsMobile();
         #endif
         return false;
     }

@TOES I'm using exactly this solution, I attached the script to a empty game object. The game runs in the editor, but when I publish it to the browser I get this error:

Any ideas?

Maybe this could help: Try to replace "UnityLoader.SystemInfo.mobile;" To "Module.SystemInfo.mobile"

Using Unity 2021.2.9f1 and I don't see 'assets/plugins/webgl/MyPlugin.jslib' am I missing something? Can someone direct me toward the location? Or, is there a 2021 equivalent?

In your Unity project folder, you should have an "Assets/plugins" directory.

The "WebGL" folder is one you can create yourself, and "MyPlugin.jslib" is a regular text file, but with a .jslib extension (instead of .txt, or *.cs).
