Instance Method


Causes the agent to evaluate its goals and update its position, rotation, and velocity accordingly.


func update(deltaTime seconds: TimeInterval)



The time step for which to update the simulation; typically, the amount of time elapsed since you last called this method.


You call this method directly on an individual agent, or on all the agents in your game through a GKComponentSystem object, whenever you want to run a step of the agent simulation. Typically, a game updates its agent simulation whenever it prepares to draw a new frame—for example, in the update(_:) method of a SpriteKit SKScene object.
