How to animate "objects" in Max/Msp.

Hello guys,

i would realize a really difficult patch for my skills. The idea is to create a sort of mini sound game. The first question is how to move objects in max/msp. I want to create a sort of algorithm that recognize the interaction between "objects". I need a guide that explain if is possible to create random or calculated movements inside the patcher. I think that this is the basic concept to realize what i mean.

The idea is to create a small virtual world in wich a defined number of objects collides together to create different sounds.

Thx for your support. It will be great if you can help me to realize this patch.
