Well, you first have to call the SPCOL command for both of the sprites then put something like this in your loop:
IF SPHITSP(0,1) THEN do whatever you want
notice the numbers in the parenthesis, those numbers have to be the management numbers of the sprites
Thanks! :D Just one more question if you dont mind, How would you make it so if you collide with a sprite it makes a sound and the second time you do it prints a word? Thanks!
