Instance Method

agentWillUpdate(_:)

Tells the delegate that an agent is about to perform its next simulation step.

Declaration

optional func agentWillUpdate(_ agent: GKAgent)

Parameters

agent

The agent object that will perform its next simulation step.

Discussion

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 position and rotation properties of the agent (as a GKAgent2D or GKAgent3D object) so that the next simulation step will take your changes to those properties into account.
