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.

Looping encounters for a never-ending world


We need at least three encounters to endlessly cycle and create a never-ending world; two can be on the screen at any one time, with a third positioned ahead of the player. We can track Pierre's progress and reposition the encounter nodes ahead of him.

Building more encounters

We need to build at least two more encounters before we can implement the repositioning system. You can create more if you like; the system will support any number of encounters. For now, add two more SpriteKit scene files to your game: EncounterB.sks and EncounterC.sks. Resize these scenes to 900 wide by 600 tall, the same as EncounterA. You can fill these encounters with Bees, Blades, Coins, and Bats—have fun! Make sure to assign the custom class attribute to the sprites that you drag into the scene editor.

For inspiration, here is my EncounterB.sks:

Here is my EncounterC.sks:

For perfect alignment with the ground, place your Blade sprites at -224 on the Y-axis.
