hello,<br><br>   i implemented a chain of cubes in bullet, that is cubes attached together by joints such that this chain forms  a closed circle, and i fix one of these cubes.<br><br>   I set up the world and the hingeconstraints between the cubes, and once i apply the gravity force, the objects move correctly.  However, now i'm trying to set the transformation of just one cube in the chain, and i want the other parts to follow in a physically correct manner, for instance, if i rotate a part, i want the parts connected to it to remain connected to it, and follow this transformation.<br><br>   i set the transformation of a part using rigidbody-&gt;setWorldTransform(trans), but it only sets the transform of one part, and when i step the simulation, the other parts don't move with the part i moved, its like they become disconnected, any idea how to fix this?<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=11150">moeizle</a> — Mon Jun 15, 2015 12:10 pm</p><hr />
