im gonna say this fast. put the command SPCOL with the sprites mannagement number after it for every sprite you want to collide with, then use sphitsp with the two sprites you want to collide with and what to do, like this SPSET 0,0 SPSET 1,1 SPCOL 0 SPCOL 1 IF SPHITSP(0,1) THEN BEEP 50 put something like that in your code (without the spsets though lol) if done right it will beep when hitting.
