Hi there,
I am writing because i started having problems with webgl + websocket + UnityPlugin in a recent version of unity 5.2.0f2 but in 5.1.0f2 was working fine.
The unity plugin i am using is here: (the one that is in the documentation)
http://files.unity3d.com/jonas/WebSockets.unitypackage
The error is a empty string when want to create a Websocket in the browser:
exception thrown: SyntaxError: Failed to construct ‘WebSocket’: The URL ‘’ is invalid.,Error: Failed to construct ‘WebSocket’: The URL ‘’ is invalid.
at Error (native)

UnityConfig.js?v=1440711594504:76 Invoking error handler due
I did a trace of the code, and i found that the communication between C# code and javascript inside a plugin of type string is done using pointers, as is in this documentation:
The problem is that in the file of the plugin: Websocket.jslib line 7,
var str = Pointer_stringify(ptr); // return empty string
Is returning a empty string, but i am sure when i create the socket i am sending the correct url.
So here are all the system versions:
SO: Mac Yosemite 10.10.1
Browser: Chrome 44.0.2403.157 (64-bit)
Unity: 5.2.0f2
Maybe the plugin is code is old? What should i change to make it work?
Thanks!
