Abstract base class for all 3D physics joints. Abstract base class for all joints in 3D physics. 3D joints bind together two physics bodies and apply a constraint. https://godotengine.org/asset-library/asset/524 Returns the joint's [RID]. 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.
