Swift Game Development - Third Edition

By: Siddharth Shekar, Haney

Overview of this book

Swift is the perfect choice for game development. Developers are intrigued by Swift 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. The book starts by introducing Swift's best features – including its new ones for game development. Using SpriteKit, you will learn how to animate sprites and textures. Along the way, you will master physics, animations, and collision effects and how to build the UI aspects of a game. You will then work on creating a 3D game using the SceneKit framework. Further, we will look at how to add monetization and integrate Game Center. With iOS 12, we see the introduction of ARKit 2.0. This new version allows us to integrate shared experiences such as multiplayer augmented reality and persistent AR that is tied to a specific location so that the same information can be replicated on all connected devices. In the next section, we will dive into creating Augmented Reality games using SpriteKit and SceneKit. Then, finally, we will see how to create a Multipeer AR project to connect two devices, and send and receive data back and forth between those devices in real time. By the end of this book, you will be able to create your own iOS games using Swift and publish them on the iOS App Store.

Building the main menu


We can use SpriteKit components to build our main menu. We will create a new scene in a new file for our main menu, and then use code to place a background sprite node, a logo text node, and button sprite nodes. Let's start by adding the menu scene to the project and building out the nodes.

Creating the menu scene and menu nodes

To create the menu scene, follow these steps:

  1. You already added the background texture assets in Chapter 8, Polishing to a Shine—HUD, Parallax Backgrounds, Particles, and More. To double-check, open Assets.xcassets and locate the Backgrounds Sprite Atlas. You should have a sprite called background-menu with the background textures for the menu scene. If not, you can find these two textures in the Backgrounds folder of the asset bundle.

  2. Add a new Swift file to your project named MenuScene.swift.

  3. Add the following code to create the MenuScene scene class:

            import SpriteKit 
     
            class MenuScene: SKScene { 
                // Grab the HUD sprite...
