I am creating a set of connected polygon shapes with associated bodies and fixtures.
I create each polygon in the same coordinate system (i.e. all have same origin, each body has position of zero) and each shape is not center around zero.
Each shape is connected with a distance joint.
When I step, things move in unpredictable ways (no gravity or forces).
My question is what is the ramifications of each shape no being not centered around zero or is it really required to create each shape centered around zero and set the body position to correct location?
Is there any torque issues?
