Hello,<br><br>     I wish to implement a chain of bodies, linked together by hinge constraints, such that if i move one body, the rest of the bodies move according to the movement and the body and the constraints.<br><br>     I want to give a transformation matrix of one part, and i want bullet to solve for the transformations of the rest of the chain (which could be cyclic), however, till now, i could not find a way to do this.<br><br>     The closest i got, was to implement all the bodies as dynamic bodies with constraints, and move one body using a force, and the rest of the bodies move accordingly.  However, this is problematic as it is very difficult for me to transform the transformation matrices i have in mind to a set of forces.<br><br>      Therefore, i wish to have a kinematic object, for which i set a transformation matrix, and the rest of the parts follow according to their constraints with the moved body, does anyone know how to do this?<br><br>Thank you,<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=11150">moeizle</a> — Mon Jun 22, 2015 10:06 am</p><hr />
