Enabling embedded resources with WebGL

As of Unity version 5.0.2p1 (available here), the IL2CPP scripting backend now supports embedded resources. The version of mscorlib.dll shipping with Unity now contains some embedded resources used for a few localization API calls. These embedded resources add about 330 KB of data (uncompressed) to the build output.

We decided not to enable embedded resources by default for WebGL builds, so that we could avoid this extra size. They can be enabled using the following editor script:

Code (CSharp):

1. using UnityEditor;
2. public class WebGLEditorScript
3. {
4.     [MenuItem("WebGL/Enable Embedded Resources")]
5.     public static void EnableErrorMessageTesting()
6.     {
7.         PlayerSettings.SetPropertyBool("useEmbeddedResources", true, BuildTargetGroup.WebGL);
8.     }
9. }

An embedded resource is data which can be written into a managed assembly, then read back out latter. It is a general tool, which is not specific to localization. You can see a few more details from MSDN here. For the mscorlib.dll with Mono, embedded resources happen to be used for localization only, but you can add embedded resources for any purpose to an assembly.

If you do choose to use embedded resources with WebGL though, make sure that you us the editor script (or something similar) above, as the IL2CPP scripting backend will otherwise ignore the embedded resources.

Embedded resources should work for iOS builds by default. There is no need to run a special editor script. If this is not working, it is a bug, so could you please submit a bug report? We would love to correct it! Thanks.

You should not have to do anything special to make embedded resources work for an iOS build. If they work with the Mono scripting backend, they should work with IL2CPP as well. Please let me know the bug report number when you submit it, and we will have a look at it. Thanks!

Thanks, we will investigate this one.

No, here "embedded resources" refers data embedded in .NET assemblies: http://stackoverflow.com/questions/3314140/how-to-read-embedded-resource-text-file
