Overview of this book

Swift is the perfect choice for game development. Developers are intrigued by Swift 3.0 and want to make use of new features to develop their best games yet. Packed with best practices and easy-to-use examples, this book leads you step by step through the development of your first Swift game. This book starts by introducing SpriteKit and Swift's new features that can be used for game development. After setting up your first Swift project, you will build your first custom class, learn how to draw and animate your game, and add physics simulations. Then, you will add the player character, NPCs, and powerups. To make your game more fun and engaging, you will learn how to set up scenes and backgrounds, build fun menus, and integrate with Apple Game Center to add leaderboards and achievements. You will then make your game stand out by adding animations when game objects collide, and incorporate proven techniques such as the advanced particle system and graphics. Finally, you will explore the various options available to start down the path towards monetization and publish your finished games to the App Store. By the end of this book, you will be able to create your own iOS games using Swift and SpriteKit.

Preface

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,...
