ok! so sprite collision is easy-ish so for every sprite you want to collide with you put SPCOL (management number) like SPCOL 0 (spcol makes it "watch" the sprite) do this for every sprite you want to collide with, lets say you want 2 sprites hitting eachother, do SPCOL 0:SPCOL 1 then you would use SPHITSP, this is for when you are making them hit, so it would be like IF SPHITSP (0,1) THEN (stuff)
