Hi Terry, There are many different ways to do collision detection. The general solution is to define some approximate geometry which represents the 'physical' or spatial presence of your object in the game world. You then test these representations against each other to see if they intersect - if they do a collision has occurred. On the Yaroze most people tend to use spheres, cylinders and boxes to represent their objects because they are easy to code for and easy on the CPU. For reference and source code try somewhere like http://www.gameprog.com/general.htm or http://www.sweetoblivion.com/resources/gameprog.html although I am sure someone has Yaroze source for this kind of thing. Also, take a look at the following threads in this newsgroup for some previous discussion on the subject Bounding box 3d collision detection / (delurk!)
