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.

Concealing Complexity with a Facade Pattern

The Facade pattern is an easy pattern to grasp because its name implies its purpose. The primary intent of the Facade pattern is to offer a simplified front-facing interface that abstracts the intricate inner workings of a complex system. This approach is beneficial for game development because games are composed of complex interactions between various systems. As a use case, we will write code that simulates the behavior and interactions of a vehicle's engine core components and then offers a simple interface to interact with the overall system.

The following topics will be covered in this chapter:

  • Understanding the Facade pattern
  • Designing a bike engine
  • Implementing a bike engine
  • A basic implementation of a vehicle's engine with the Facade pattern
This section includes a simplified version of the implementation of an engine...
