Add the Player Agent to the Component System

Switch to the GameScene.swift file and look at the didMove(To:) method. Notice there’s a lot of player-related code stuffed into this method. Let’s tidy up this method by moving the player-related code into its own set-up method.

Below the setupCamera() method, add the following code:

func setupPlayer() {
  player = childNode(withName: "player") as? Player

  if let player = player {
    player.move(.stop)
    agentComponentSystem.addComponent(player.agent)
  }
}

Essentially, this is the same code that’s currently in the didMove(to:) method with one exception: you’re adding the player.agent component to the agent component system so that it participates in the update routine.
