It appears that my sprites collide even when not touching by their bounds. Is there any way to fix this problem?

You can use SPCOL Management Number, Star point X, Start point Y, Width, Height to specifie the collision box.

But will it really fix my problem?

Also, with SPHOME being 8,8 out of a 16x16 sprite, would the bounds be -8,-8,8,8?

No, SPHOME only edit the reference point of the sprite. You need to call SPCOL again to generate the new boundaries of the sprite. Run this program and see it by yourself: =========================================== SPSET 0,0 SPCOL 0 SPHOME 0,8,8 SPCOL 0 OUT X,Y,W,H ? FORMAT$("X:%D Y:%D W:%D H:%D",X,Y,W,H) SPHOME 0,8,8 SPCOL 0 SPCOL 0 OUT X,Y,W,H ? FORMAT$("X:%D Y:%D W:%D H:%D",X,Y,W,H)

Perhaps that is why my sprites kept colliding when not touching...
