Once a node has a boundary, collisions between other nodes can be detected and the physics engine used to apply real-world physics to the node such as causing it to bounce when hitting other nodes. The use of contact bit masks can be employed to specify the types of nodes for which contact notification is required.
The physics body also allows forces to be applied to nodes, such as propelling a node in a particular direction across a scene using either a constant or one time impulse force. Physical bodies can also be joined together using a variety of different join types (such as sliding, fixed, hinged and spring based attachments).
Finally, the SKView instance renders the new scene frame before the loop sequence repeats once again.
