Game Development Patterns with Unity 2021 - Second Edition

By: David Baron

Overview of this book

This book is written for every game developer ready to tackle the bigger picture and start working with advanced programming techniques and design patterns in Unity. Game Development Patterns with Unity 2021 is an introduction to the core principles of reusable software patterns and how to employ them to build components efficiently. In this second edition, you'll tackle design patterns with the help of a practical example; a playable racing game prototype where you’ll get to apply all your newfound knowledge. Notable updates also include a game design document (GDD), a Unity programming primer, and the downloadable source code of a complete prototype. Your journey will start by learning about overall design of the core game mechanics and systems. You’ll discover tried-and-tested software patterns to code essential components of a game in a structured manner, and start using classic design patterns to utilize Unity's unique API features. As you progress, you'll also identify the negative impacts of bad architectural decisions and understand how to overcome them with simple but effective practices. By the end of this Unity book, the way you develop Unity games will change – you’ll adapt a more structured, scalable, and optimized process that will help you take the next step in your career.

Managing Dependencies with the Service Locator Pattern

This chapter will be brief because the Service Locator pattern we will review is simple and efficient. The core idea of this pattern is straightforward: it revolves around having a central registry of initialized dependencies. But to be more precise, these dependencies are components that offer specific services that we can expose with interfaces we call "service contracts". Hence, when a client needs to call upon a particular service, it doesn't need to know how to localize and initialize it; it just needs to ask the Service Locator pattern, and this will do all the legwork to fulfill the service contract.

As we will see in this chapter, it's quite a simple design and is easy to implement.

In this chapter, we will cover the following topics:

  • Understanding the Service Locator pattern
  • Implementing...
