i am a artist and a programer. i program with c/c++ and vb 7.0. i just wanted to know how to program an interactive environment.ex: say i am playing a game, how can i tell the pc to stop at the wall and apply the animation of getting a hit.

You have to use collision detection algs. Go look up collision detection on this site.

thanks but the site u gave me has nothing about collision detection or anything related to game dev.

Here are a few sites on collision detection and game physics:


http://www.peroxide.dk

http://www.experts-exchange.com/Programming/Game_Development/AI_Physics/

http://www.ddj.com/documents/s=983/ddj9513a/9513a.htm

http://www.devseek.com/Programming/Graphics/Algorithms_and_Data_Structures/Collision_Detection/

If none of these work, try a search engine.

Good Luck!
