Armature Radgoll physics and Object Collision

Hi there, i’ve been trying to find out how to do this by myself, but i can’t find out how to do it.

I’ve ust rigged the model for my character in Hellfire, my game, but what i need right now are ‘‘armature radgoll physics’’ and ‘‘Object Collision’’, i`m wondering if this is possible in blender?. The armature radgoll physics is something like this: at 0:33
