Do you know how to make the actor disappear without placing the 'end of world' condition on it? If so, do you know how to place an object that is in the world at any edge of the world? What have you tried so far?

No, I dont know know how to make the actor disappear without the "end of world" condition, but I know how to place an actor at the edge of the world. I have primarily tried if statements and boolean conditions for this and no luck. Thanks for helping me.

You need to show the actual code you tried. It would be hard to explain why your attempts did not work without them. I would rather help you out both here AND in the long run than you going on blindly from here.
