Garr Godfrey writes REMEMBER! Since your object only move a few pixels at a time, the overlap region will only increase by a tiny amount every time. Thus, you can greatly optimize by only checking the border of the overlap region with the number of pixels that you have moved. Not a good idea. As the relative position of the two objects has changed there may very well be a new collision in the old overlap area. Carl Edman
