Hint joint how to configure
i am beginer and i have cube in air with element attached him with no rotation like a node, i have a couple cubes for simulate rope with hint joint. i have clicking right click at a cube and spawn rope from direction player to node and attaching last element rope with player and this working very vell. when player doesnt have velocity, and blocked rotation on rigidbody elements. but sometimes if i have been jumped and try to spawn rope in moving elements rope have weird rotations, and sometimes cubes rotation blocks. how i could work with rotations rope or i dont know, any advice? thanks. p.s sorry for bad english.

can put code from github with project I experimented here trying to achieve obedience, but I am convinced that this is the wrong direction, I just do not know how to work with rotations, I got confused if (i == 1) { joint.autoConfigureConnectedAnchor = true; } else { joint.autoConfigureConnectedAnchor = false; joint.connectedAnchor = new Vector3(0f, -0.4f);
