Renovating the GameScene class

We have made quite a few changes to our project. Luckily, this is the last major overhaul of the previous animation code. Moving forward, we will use the terrific structure we built in this chapter. At this point, your GameScene.swift file should look something like the following:

import SpriteKit

class GameScene: SKScene { 
    let cam = SKCameraNode() 
    let ground = Ground() 
    let player = Player() 

    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 


        // Spawn our test bees: 
        let bee2 = Bee() 
bee2.position = CGPoint(x: 325, y: 325) 
self.addChild(bee2) 
        let bee3 = Bee() 
bee3.position = CGPoint(x: 200, y: 325) 
self.addChild(bee3) 

        // Add the ground to the scene: 
ground.position = CGPoint(x: -self.size.width * 2, y: 150) 
ground.size = CGSize...
