|
A physics joint that connects two 3D physics bodies in a way that simulates a ball-and-socket joint. The twist axis is initiated as the X axis of the [ConeTwistJoint3D]. Once the physics bodies swing, the twist axis is calculated as the middle of the X axes of the joint in the local space of the two physics bodies. Useful for limbs like shoulders and hips, lamps hanging off a ceiling, etc.

Swing is rotation from side to side, around the axis perpendicular to the twist axis.

The swing span defines, how much rotation will not get corrected along the swing axis.

Could be defined as looseness in the [ConeTwistJoint3D].

If below 0.05, this behavior is locked.
