Swift Game Development - Third Edition

By: Siddharth Shekar, Stephen 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.

Chapter 5. Spawning Enemies, Coins, and Power-Ups

One of the most enjoyable and creative aspects of game development is building the game world for your players to explore. Our young project is starting to resemble a playable game after adding the controls; the next step is to build more content. We will create additional classes for new enemies, collectible coins, and special power-ups that give Pierre Penguin a boost as he navigates the perils of our world. We can then develop a system to spawn increasingly difficult patterns of these game objects as the player advances.

The topics in this chapter include the following:

  • Adding the Power-up Star

  • A new enemy—the Mad Fly

  • Another terror—Bats!

  • Guarding the ground with the Blade

  • Adding coins

  • Testing the new game objects
