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.

Reviewing the implementation

We completed the process of building a quick input replay system by using the Command pattern as our foundation. Of course, the code example in this chapter is not production-ready and very limited. Nevertheless, the goal of this chapter was to learn how to use the Command pattern with Unity, and not design an entire replay system.

In the game prototype project in the FPP folder of the GitHub project, we did implement a more advanced example of a replay system that includes serialization and a rewind feature. We recommend checking it out and, of course, modify it at your discretion.

In the next section, we will review some alternatives solutions and approaches that we could have used to build our replay system.
