1. What is the code used to making walls/blocked areas? I want to make a game, but I need to make the characters stop at the edge of the screen, and on some objects.

2. With tile arrays, how do i define each tile? Like say I had tile 1 and 0. How do I make my tile in the library be tile 1 or 0?

3. Maps. How do I make multiple maps, lets say 5. Are they frames? Layers? I have no clue how to do it.

4. Doors, once I figuire out maps, I want to make doors so I can get from one map to another.
