Constrains two bodies to rotate around a shared pivot point.
|pivot||The location of the pivot point relative to the parent body.|
|bodyB||The other body that the constraint attaches to.|
|impulse||The magnitude of the impulse this constraint applied last frame.|
|maxForce||Maximum force the constraint is allowed to use.|
|errorBias||Rate that error (stretching of the constraint) is fixed.|
|maxBias||Maximum rate that constraint error is fixed.|
