(Almost) full screen mode! Yes, I will be making arrow buttons that point the other way. I have a question regarding sprite collision - what determines the priority of the collision that SPHITSP picks up? I have the white and black keys here, and the black ones are seperate sprites that sit on top of the white ones and are, of course, supposed to play their own notes.

The problem is, only the white keys are detected - unless, of course, the white keys are removed, in which case the black ones work fine, so the problem must be priority. The control number of each black key is one greater than the previous white key, if that helps. The black keys are also at -32 in Z.

Heres what I would suggest- First, Move the white keys off screen before checking for the black ones. Next, move them back to their original spot. Finally, if none of the black keys ones were pressed, check for the white keys.

Perhaps - I'll experiment. SPHIDE and SPSHOW should do pretty much the same thing.

Figured it out - apparently lower management numbers are treated as priority with collision, so I changed the order of which the keys are set.

Awesome!
