Try a simple program, like this: SPCOL(MG1) SPCOL(MG2) HIT=SPHITSP(MG1,MG2) IF HIT THEN IF BUTTON(2) AND- 16 THEN BEEP 7 MG1 and MG2 are Management Numbers, which is the 1st number you put in SPSET (In SPSET 3,4 , 3 is the management number) This all means is if MG1 touches MG2 then allow IF BUTTON(2) AND 16 THEN BEEP 7. If you have any questions, i dont mind answering!
