[Box2D] Pivot of body's rotation

Newbie & Debugging Questions
#1

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?

#2

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

#3

Rendering pivot is always the local coordinates origo.

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

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)
