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.

Configuring the path particle settings


To create Pierre's dot trail, update your particle settings to match the settings shown in this screenshot:

Let's go through each of these basic parameters to understand what each of these variables do and how, by changing each of the parameters, the behaviors of the particle system can be changed.

Name

If you want to refer to the particle system by name in code, we can give a name here so that we can refer to it later. This is similar to how we gave a name to the enemyNode to check whether the node passed into the movingSprite class was the enemy, and then we run a certain function based on that information.

Background

This is the color of the background. Changing this doesn't affect the particle itself. This is purely for the purpose of visibility. If our particles are black, we can change the background to white so that we can see clearly how the particle looks and behaves.

Texture

This is the texture or image that will be displayed for each particle. Currently...
