I am having so much trouble using sprite masks. Say I have a back ground image calle Tile, a sprite call Character, and a sprite mask for it called Mask. I try to PUT them on the screen using this:
PUT (0,0), Tile, PSET
PUT (0,0), Mask, AND
PUT (0,0), Character, XOR
and I get an error when I try to PUT the mask on screen. Help!
I can't get this vital thing to work!
