I want to make a starfield for a game, the script should be something like this:

If (GetProperty ("/star", _x) > center)
. SetProperty ("/star", _x) = (GetProperty ("/star", _x)+. (GetProperty ("/star", _x) - center
End if

But then you see just sprites of round stars, and I'd like to add some kind of a motion blur, the star must heve some kind of a tail.

Does anyone know?

Thanx,
