Character Joints are mainly used for Ragdoll effects. They are an extended ball-socket joint which allows you to limit the joint on each axis.
If you just want to set up a ragdoll read about Ragdoll Wizard.
|Connected Body||Optional reference to the Rigidbody that the joint is dependent upon. If not set, the joint connects to the world.|
|Anchor||The point in the GameObject's local space where the joint rotates around.|
|Axis||The twist axes. Visualized with the orange gizmo cone.|
|Swing Axis||The swing axis. Visualized with the green gizmo cone.|
|Low Twist Limit||The lower limit of the joint.|
|High Twist Limit||The higher limit of the joint.|
|Swing 1 Limit||Lower limit around the defined Swing Axis|
|Swing 2 Limit||Upper limit around the defined Swing Axis|
|Break Force||The force that needs to be applied for this joint to break.|
|Break Torque||The torque that needs to be applied for this joint to break.|
Character joint's give you a lot of possibilities for constraining motion like with a universal joint.
The twist axis (visualized with the orange gizmo) gives you most control over the limits as you can specify a lower and upper limit in degrees (the limit angle is measured relative to the starting position). A value of -30 in Low Twist Limit->Limit and 60 in High Twist Limit->Limit limits the rotation around the twist axis (orange gizmo) between -30 and 60 degrees.
The Swing 1 Limit limits the rotation around the swing axis (green axis). The limit angle is symmetric. Thus a value of eg. 30 will limit the rotation between -30 and 30.
The Swing 2 Limit axis doesn't have a gizmo but the axis is orthogonal to the 2 other axes. Just like the previous axis the limit is symmetric, thus a value of eg. 40 will limit the rotation around that axis between -40 and 40 degrees.
You can use the Break Force and Break Torque properties to set limits for the joint's strength. If these are less than infinity, and a force/torque greater than these limits are applied to the object, its Fixed Joint will be destroyed and will no longer be confined by its restraints.
