In Chapter 6, Generating a Never-Ending World, we will build a never-ending level by spawning tactical obstacle courses full of these new game objects. We need to clear out all of our test objects to get ready for this new level-spawning system. Once you are ready, remove the new test code we just added to the GameScene class. Also, remove the six lines that we have been using to spawn the Bees from previous chapters. Finally, uncomment the line in Player.swift that sets Pierre's forward velocity (if you chose to comment it out when testing the new classes in the previous section).
When you are finished, your GameScene class' didMove function should look like this:
override func didMove(to view: SKView) {
self.anchorPoint = .zero
self.backgroundColor = UIColor(red: 0.4, green: 0.6, blue:
0.95, alpha: 1.0)
// Assign the camera to the scene
self.camera = cam
// Add the ground to the scene:
ground.position = CGPoint(x: -self.size.width * 2...
