Ah, that's what I was looking for thanks.

ps: interesting commentary on the Stainsor's wall effect. Parmenides would beg to differ. For it was said,

"Helplessness guides the wandering thought in their breasts; they are carried along deaf and blind alike, dazed, beasts without judgment, convinced that to be and not to be are the same and not the same, and that the road of all things is a backward-turning one"

Hi deadeye, thanks for your swift reply. Would the method above be appropriate if I were to use it in the ghost shooter tutorial to prevent the monsters and the player from moving off screen?

Hi guys, I've been through some of the tutorials, forums posts and documentation but I can't seem to find the parameter/code to prevent objects from moving off screen. By objects, I mean those that I've assigned movement behaviors to. Would appreciate it if someone could point me in the right direction.

Thanks
