aaahhhh, you meant in an actor space - actor events and use there drawing. Here you are right, polygon will be behind the actor.
I have done it in scene using the calculations of X and Y of the actor and then draw image for this actor employing X and Y. So I used X and Y of the actor space in the screen of the scene and then in the drawing mode.
But now I don't know how to apply the behaviour for my actor on the polygon. Any ideas?
