Only walk on tiles

[WauloK]

I have an idea for a game. I want to make a set of tiles for a character to walk on and the rest of the screen is just background which he doesn't walk on.
I'm trying to think of the best way to do this in GE. That is, I have the tiles as actors (or tiles?) on the screen to walk on and the character ONLY walks on these tiles.
I spose I can make an array showing what tiles are where, but maybe there's another easier way.

There sure is. Use wireframe actors and collision detection against them to limit movement.

Or make another set of tiles where you don't want to be able to walk, and either put a background on them or make them invisible.
