Please help with collision (and now a beat movement system)

hmmm, do you mean keep the beats but make enemies move every 4 beats, if so then that would be hard to do unless someone else helps out

not exactly. making an enemy beat system would be easy, its just coding the enemy to come get closer to the player and then making the enemy attack if there were to be a life/health system, ill try though.

I mean coding a beat system for the player.
