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.
You’re almost done and ready to test. In the didMove(to:) method, remove the following two lines of code:
| | player = childNode(withName: "player") as? Player |
| | player?.move(.stop) |
and replace them with this one-liner instead:
| | setupPlayer() |
Excellent, the didMove(to:) method is cleaner, but there’s still one more thing you need to do: get the monster entities to participate in the updates.
