The explanation isn't great and we can't see what you're seeing so have to imagine it. Guessing though, you could give enemies an instance variable numbered 0,1,2,3 etc and use a global variable alongside it. Always point the view at the enemy where the instance variable matches the global variable. If you're moving left/right with the keyboard you can subtract/add 1 from the GV. So if GV=1 it points at the enemy where enemy.variable=1
