The COLUPF register sets the color of the playfield and the ball. You can change the color from one scan line to the next, and potentially in mid-scanline. But when the the ball and the playfield are both being drawn on the same line you have the potential for the two objects blending together. The easy way out is to make the playfield empty, so the character is never really on top of the playfield, but on top of the background. The COLUBK register sets the color for that, so it can be different than the ball. Use the playfield registers to fill in *around* the area where the player and ball graphics sit on top of the background to create the illusion of walls. -- mor@xxxxxxx http://www.crl.com/~mor/ -- To unsubscribe, send the word UNSUBSCRIBE in the body of a message to stella-request@xxxxxxxxxxx
