@Scrott, Have you tried setting the skeleton position after your for loop? this did the trick for me, that's of course if I understood your problem right.

@Nate, Thanks

@Nate, Hello, I'm sorry, I didn't get the "subject the bone's world rotation part". English just isn't my primary language, could you please explain?
Thanks

Edit: I did this: (box2dBodyRotation * radiansToDeg) - bone.getParent().getWorldRotation()
It works fine but I don't know if it's the right way.

@hsanchezp, Hello again, I have a question: are you applying rotations from physics to the bone? if you are, could you possibly tell me how you did do it?
Thanks

I've tried using the bone's matrix not the parent's but in java libGDX and it didn't work. so I used its parent and that worked for me. just a tip, idk how it is in Corona.
