Hi all I looked at the articles in GameDev but they didnt help much,if someone can lead me to a good tutorial or a book i can buy it would be appreciated thxs.

look for a detailed tutorial here:

which originally came from an article here:
http://www.fluidstudios.com/publications.html

(they have a wicked hardware 3d collision demo, but the softare one sucks)

and for everything else look at:
http://www.geometryalgorithms.com/

here''s me taking advantage of the above collision detection and responce system (it''s the same thing, but in 2d... still, is a good example of how good it is):
