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.

Adding a health crate


We have taken many steps to create our crate system. Now we can add our first crate: a crate in the GameScene class that will award health points to the player. Follow these steps to wire up the heart crate:

  1. In GameScene.swift, instantiate a new instance of the Crate class as a property of the GameScene:

            let heartCrate = Crate() 
    
  2. At the bottom of the GameScene didMove function, add the heartCrate to the node tree and call the function that makes it award a heart:

            // Spawn the heart crate, out of the way for now 
            self.addChild(heartCrate) 
            heartCrate.position = CGPoint(x: -2100, y: -2100) 
            heartCrate.turnToHeartCrate() 
    
  3. Locate the GameScene.didSimulatePhysics function. Find the code that spawns the power-up star. We can add on to this code to spawn our heart crate randomly after some encounters. Add the following code below the starRoll conditional (new code in bold):

            // Each encounter has a 10% chance...
