|phase||The initial angular difference of the bodies' rotations in degrees.|
|ratio||The gear ratio.|
|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.|
