Base class for all 3D joints. Joints are used to bind together two physics bodies. They have a solver priority and can define if the bodies of the two attached nodes should be able to collide with each other. https://godotengine.org/asset-library/asset/524 If [code]true[/code], the two bodies of the nodes are not able to collide with each other. The node attached to the first side (A) of the joint. The node attached to the second side (B) of the joint. The priority used to define which solver is executed first for multiple joints. The lower the value, the higher the priority.
