In order to render my Box2D bodies correctly, I need to know the pivot that the body is rotated around. How can I retrieve such a thing?

Having never worked with Box2D myself... Google said the center of mass (and hence the pivot) can be found with MassData.

Rendering pivot is always the local coordinates origo.

Ow wow. This was a stupid question to ask Cheesy I didn't realize that body.getAngle() + body.getPosition() is completely enough to render sprite correctly. Silly me Cheesy

I guess I have another question now. When my objects pick up just a little bit of speed (falling just for a few seconds) they seem to start jiggling around. Is this normal? (Its like rendering not at floats, but casting position of object to int, but not that bad looking, on a much smaller scale)
