Hopefully the title makes some sense.
The easiest way for me to describe the problem was to make this image:
So as the image suggests, I want the ring to be joined at a custom part of it’s physics body, not just in the center. When I put the anchor positions into the pivot joint, it still affixes the joint to the center of the ring.
Can anyone think of a good solution for this?
That should definitely be possible. Can you show a snippet of your code where you create the objects and the pivot joint? That way we can figure out why it’s not working.
One thing to note: when you create an off-center pivot joint, the hybrid and debug draw modes show lines emanating from the center of each object to the pivot joint. I wanted to mention that in case it’s the source of any confusion.

Ah well that’s probably all it is then.
For the record though, my code is simply this:
ringPivot = physics.newJoint( "pivot", ring, pins, pin.x, pin.y - pin.height \* 0.5)
So it should work as I explained, maybe the hybrid lines are what threw me.
Yeah, that looks fine to me. It should be easy to test too: just apply a force to one of the objects, or make it touchable, and see whether the joint is where you want it to be.
