Can one of you, tell me the complete way to keep one image from entering another? Like in Zelda 1, where you can't walk into trees, or bricks. But you can walk anywhere on the floor you'd like.

Let's say you have two objects of equal size, and one moves at the speed of 20 increments per keypress. You don't want object 1 to enter object 2. How would you stop this?

Please tell me the full code, or as much as you know.

That is all.
