Drawing Sprite A...Over WhiteOver BlackOver Sprite BPt-OnABlackA OR BPt-ChangeAA InvertA XOR BPt-OffAAAAlso, xoring twice is the same as removing since (A xor B) xor B = A
yep, it erases a 8x8 square then draws a sprite.I wonder if it's slower than Pt-On? I mean, for example, would ClrDraw then Pt-On('ing 96 sprites be faster than Pt-Off('ing 96 sprites? (assuming they need to be displayed every frame)
