Are those components ready in Unity 5.2? I mean, can we start developing some projects on it, knowing that in the near future they will be working 100%? Or are they just broken right now and not compatible with each other? Is there a roadmap?
In 5.2 the UNet transport layers supports WebGL by using WebSockets instead of UDP. The UNet High Level API is not supported on WebGL yet, but work is happening to add that support for it in a 5.2 patch release.
So, it's safe to say that we can use UNet normally right now and expect WebGL to be supported in the future?
