What I was wondering is this, is there a piece of code or like some sample code that uses dirty triangles to move around like 2 bmp/sprites on the screen? Just something basic like that so it would be just a matter of duplicating it many times to get more objects. To me atleast the dirty triagle stuff is a little strange mainly because I'm use to doing the old double buffer method.
