Fox or whoever,

I saw a thread about how a person setup a tile map using DirectDraw adn the map looked something like this...

1203104
2012310
3122310
3122310

Where 0 would be grass, 1 whatever, 2 whatever, and so on...

Do you know what I mean??? I hope so...

My question is... What is the principle behind this? It seems like a pretty simple way of doing things, if I could only grasp the concept.

I'm pretty new to direct draw, so you might want to be a little explanitory in your reply...

Thanx in Advance,
