Base class for all 3D joints
- bool collision/exclude_nodes - If
truethe two bodies of the nodes are not able to collide with each other.
- NodePath nodes/node_a - The Node, the first side of the Joint attaches to.
- NodePath nodes/node_b - The Node, the second side of the Joint attaches to.
- int solver/priority - The order in which the solver is executed compared to the other Joints, the lower, the earlier.
All 3D joints link two nodes, has a priority, and can decide if the two bodies of the nodes should be able to collide with each other
