ocular rewritten

I am trying to make 2 clones of the same sprite move towards each other, but at the same time I am also using a camera system to allow the player to move around and see the whole playing field. But due to the camera, I can really only use Change X and Change Y to make the clones move. I am having trouble having the clones move towards each other because of this, does anybody have any idea of how to make it so they move towards each other?
