Hey guys, I'm making a simple game where I want to attach two spheres together (actually it's many sphere but I can't even attach two together yet). One of them will be rotating about and the other should attach to it and just simple spin with it. I can't think of a good way to go about doing this. Any suggestions?

I just realized that wasn't very specific. Let me explain what I'm trying to do exactly. I'm going to have a big grey sphere in the middle of the screen which you can control by rotating counter clockwise or clockwise. Other spheres are coming at you from all different directions. When they impact with you they should attach but not overlap with the grey sphere. I would want the point of impact to be the point of attachment.

I hope that makes a bit more sense.
