The agent object that will perform its next simulation step.
Implement this method when you want to update the agent simulation with data from an external source, such as node position and orientation information updated by the SceneKit or SpriteKit physics engine. Set the
rotation properties of the agent (as a
GKAgent3D object) so that the next simulation step will take your changes to those properties into account.
