GUI to WorldSpace

Hello.

I’m searching for a way to convert a gui to a worldspace.
I can’t figure it out how to to it.
I would prefer to get a small example! :smiley:
(no Unity 4.6)

thanks

var screenPos = guiPos;
screenPos.y = Screen.height - screenPos.y;
var worldPos = Camera.main.ScreenToWorldPoint(pos);
