Is it possible to center the screen coordinates, so that 0,0 is the center of the screen?
A Cartesian coordinate system (also known as a rectangular coordinate system) is used to
de"ne position. Unlike standard Cartesian coordinates, the origin of the screen is located at
the top-left corner so that positive y-coordinate values extend downward (positive x-values
extend to the right as usual). All screen coordinates are de"ned relative to this origin [import]uid: 4596 topic_id: 8394 reply_id: 308394[/import]
