In my game, there are cars and there is a tow truck. I added code to the tugboat that hooks the cars using CharacterJoints and created presets of clutch point parameters for each car in advance. The cars are hooked and unhooked with no problem. But the problem is that Rigidbody of the hooked car goes into “convulsion mode” and the car starts throwing in different directions, but when unhooking it starts working normally. I hitch cars using a rigid hitch - an additional Rigidbody object to which the car is hitched, because if you hitch directly to the tow vehicle, the turning radius will be too large. I checked, the tug doesn’t cause these “convulsions” (I hooked a simple cube without wheels to it and rolled it all over the map and it behaved normally). I also specified in the code of the machines that during towing their Rigidbody velocity.y and angularVelocity.y is 0 and this partially solved the problem, the machines became less jerky on the Y axis, but on the other axes “convulsions” became stronger.
