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.

What are design patterns?

For those that are very new to programming, design patterns might be a novel concept. The simplest way of explaining design patterns is that they are reusable solutions to common software development problems. An architect named Christopher Alexander originated the notion of design patterns to describe reusable design ideas. In the late 1980s, inspired by the concept, software engineers started experimenting with applying concepts of reusable design patterns to software development, and over the years several books were written on the subject, such as the classic Design Patterns: Elements of Reusable Object-Oriented Software by the so-called "Gang of Four".

But in this book, I will be avoiding covering the academic side of software design patterns, focusing instead on their practical use for programming game mechanics and systems in Unity. I will present a recurrent game programming problem in each chapter and propose resolving it using a specific design pattern adapted for the Unity application programming interface (API).
