init(bodyA:anchorA:bodyB:anchorB:)
Creates a ball and socket joint connecting two physics bodies.
Declaration
convenience init(bodyA: SCNPhysicsBody, anchorA: SCNVector3, bodyB: SCNPhysicsBody, anchorB: SCNVector3)Parameters
- bodyA:
The first physics body to be connected by the joint.
- anchorA:
The point at which the joint connects, relative to the node containing the first body.
- bodyB:
The second physics body to be connected by the joint.
- anchorB:
The point at which the joint connects, relative to the node containing the second body.
Return Value
A new ball-and-socket-joint behavior.
Discussion
For a behavior to take effect, add it to the physics simulation by calling the addBehavior(_:) method on your scene’s SCNPhysicsWorld object. The physics bodies constrained by the joint must be attached to nodes in the scene.
