2 Things.
1.) You haven't set collision on the objects at all. So how can an object collide, if it hasn't been defined collision properties?
First
set object collision on objnum
Then, one of these three.
set object collision to boxes objnum
set object collision to spheres objnum
set object collision to polygons objnum
2.) From browsing your source it looks okay, but make sure when collision occurs your telling your object that it can't move forward anymore(or whatever direction), and force it to move the other way.
