thanks for the tips and advice

this sounds close to my thoughts and I will look into it - thanks

I think I fixed your issue. I took out the 2 out radio buttons from dynamic panels and assigned them into a radio group. A small piece of advise - start naming dynamic panels, its really hard to figure thing out inside the prototype. Not sure how you were able to handle that.

I believe the .position.Set one is part of the b2BodyDef class? That is what you use when first defining the body to create it. Its not really necessary since you can do the .SetPosition on the body after its created.
