Fix NaN due to division by zero

Open zhutq opened this issue 1 year ago • 2 comments

I encountered NaN when simulating with a kinematic rigid body, one dynamic rigid body, and one rope anchored between them. It was solved by avoiding division-by-zero when computing solverConstraint.m_jacDiagABInv.

I would also appreciate clarification on this, as I also ran into this NaN when trying to use a fixed point type for btScalar, and I'm not certain what the proper behavior is supposed to be.
