I have a simple drive on a pxD6Joint. I am using this as a revolute joint with the twist degree of freedom. And I want to know the force applied by the drive. How do I get that value? Lets say, that for actor0, actor1, constraints frames all have the same orientation but different location with the twist along the x axis. I tried doing a joint->getConstraint()->getForce(force, torque). But that does not appear to include the force generated by the drive. So lets say, I project the torque onto the actor1’s xaxis, the value is always zero. But the drive is clearly exerting a non-zero torque as my mechanism is moving as expected.
Is there any way I can extract this piece of information?
