WWW in background thread.

Unity Engine
1

Hi all, I’m attempting to use the WWW class to get a large XML file in a background thread. I get the following error:

UnityEngine.WWW:InitWWW(String, Byte[ ], String[ ])
UnityEngine.WWW:.ctor(String, Byte[ ], Hashtable)
UnityEngine.WWW:.ctor(String)
Walls:GetWallsFromServer() (at Assets/Scripts/Walls.cs:94)

Not sure how to interpret that since it seems to point to an internal initialization problem. Is it not possible to use WWW outside of the main thread? If not, why is it this way Unity folks? This is the type of thing that should definitely be able to run outside of the main.

Thanks!

You can not use anything from UnityEngine outside the unity thread in generally, so a no there (exception seems to be Debug.Log but thats likely more cause the OS or Mono handles the concurrent file accesses there). Reason is that Unity is not threadsafe!

But you also don’t need it for WWW as WWW is always in an internal workerthread, it does not run on the engines own thread.
