Why does that work? Doesn't that just override the greenfoot setLocation, so instead of moving the Actor, all you do is change some local variables?

I think i found a bug in the map system. When you don't have the map turned on and you die, it brings you back and turns the map on, except now none of the enemies or special items show up on the map! By the way, did you hack greenfoot or something? I was playing with the source, and i was able to move the actors all the way off the screen! And sometimes it wouldn't even let me select them after I moved them!

You can lock on, just press the right mouse button to activate it. I took it off because some people can aim better without and anticipate the enemies movements
