Hi!

I've found some very useful articles in this discussion board regarding collision detection. However, I have one more question:

how to efficiently perform a collision detection between the sprite and a map tile?

I'm making a small test tile-based game, so I've stored my map in a 1-dim. array. each tile contains x, y, type, and whether it is passable or not... So, now I check the sprite's position, then perform a lot of calculating to see where the sprite is, relative to the tile....Again a lot of calculating (if you wish a code snippet, I can post it...).

So, I wonder how do you do it in your games, programs,or how do they do it in those commercial games? I tried to igure it out by a little decompiling, but with no luck...

Some code will be very very helpful!!!

Thanx
