Game Development Patterns with Unity 2021: Explore practical game development using software design patterns and best practices in Unity and C#

Solve your programming woes in Unity with practical design propositions

Key Features

• Gain a comprehensive overview of Unity engine architecture and coding model
• Build a complete racing game using software design patterns and understand how to implement them in Unity
• Download the source code of the complete prototype demonstrating each of the software patterns used

Book Description

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 you will learn

• Structure professional Unity code using industry-standard development patterns
• Identify the right patterns for implementing specific game mechanics or features
• Develop configurable core game mechanics and ingredients that can be modified without writing a single line of code
• Review practical object-oriented programming (OOP) techniques and learn how they re used in the context of a Unity project
• Build unique game development systems such as a level editor
• Explore ways to adapt traditional design patterns for use with the Unity API

Who this book is for

This book is for Unity game developers who want to learn industry standards for building Unity games. Knowledge of the Unity game engine and programming in the C# language is a must, so if you’re a beginner, try our Learning C# by Developing Games with Unity 2021 handbook instead.
