This script is useful when you have a skinned mesh with lots of bones that are parented to each other as a chain. Useful for long ropes and cables which use Physics simulation.
Quickly Connecting Character Joints
First, add a Character Joint and a Rigidbody to all the bones of the rope armature. You can select all the bones in the Hierarchy and add the components to all of them at once. The script will take care of the connected bodies.
Attach the script to the last bone, then click on the component menu, and choose Connect Joints Upward.
The bones are now connected, and you no longer need this component. You can tweak the joint parameters, rigid bodies and colliders all at once.
The swinging trap uses character joints and physics simulation for the cable.
