Hello,

could you please submit the faulty project using the bug reporter and paste the case number here? We will look at it as soon as we can and fix it for one of the upcoming betas.

Thanks,

After investigating this bug, it looks like the PlayMaker code is trying to use UnityEngine.NetworkPlayer, which is not supported in WebGL. Unity is not doing a very good job of reporting the error, IMO. If I dig into the Editor.log file, just above the TypeLoadException, I see this:

-----CompilerOutput:-stdout–exitcode: 1–compilationhadfailure: True–outfile: Temp/Assembly-CSharp.dll

In the PlayMaker code, this access to UnityEngine.NetworkPlayer is usually inside a #if like this:

#if !(UNITY_FLASH || UNITY_NACL || UNITY_METRO || UNITY_WP8)

I think that the code should be changed to this:

#if !(UNITY_FLASH || UNITY_NACL || UNITY_METRO || UNITY_WP8 || UNITY_WBEGL)

simply adding UNITY_WEBGL to the list of exclusions.

So at least initially, I don’t think this is a bug we can correct on the Unity side.

thanks for your help!

@kryptopath2 Are you using the Playmaker 1.8.0 beta? Did you import PlayMakerNACL.unitypackage into your test project? Networking is stripped from that version. All actions should already have UNITY_WEBGL in the list of exclusions…
