Streamline game development with proven design patterns and create scalable, reliable architectures effortlessly Key Features Save time and avoid pitfalls in game development with proven design patterns - Leverage the tools in the Godot editor to benefit from native implementations of design patterns such as the observer and singleton - Learn SOLID principles and refactoring techniques to build scalable, reusable architectures for robust games - Purchase of the print or Kindle book includes a free PDF eBook Book Description Game development demands more than just creativity; it requires code that’s as dynamic and adaptable as the games you dream of creating. Seasoned Godot developer, educator and creator of popular resources like The Essential Guide to Creating Multiplayer Games with Godot 4.0, Henrique Campos introduces you to object-oriented programming design patterns, offering time-tested, reliable solutions to common coding issues. With these patterns, you’ll not only build scalable, maintainable architectures for your games but also gain the confidence to tackle real-world development challenges head-on with Godot's built-in features. In this hands-on guide, you’ll step into the role of a game mechanics engineer tasked with implementing requests from a fictional game designer, simulating the collaborative nature of real-world game development. Using Godot 4.3, you’ll develop a complete platformer game featuring a playable character, enemies with advanced AI, interactive objects, multiple levels, music, and more. Along the way, you’ll master core programming concepts such as SOLID principles, favor composition over inheritance, and have a solid understanding of object-oriented programming along with the principles behind the design patterns. By the end of the book, you’ll be able to diagnose and fix pathologies in your code with ease. What you will learn Create reusable and scalable code that follows SOLID principles - Identify common game development issues and apply industry-standard solutions - Understand feature requests and how to turn them into concrete solutions leveraging design patterns - Analyze game development pathologies to figure out underlying issues - Architect reliable systems that are understandable, intuitive, and scalable - Structure professional, collaborative game systems that are easy to maintain Who this book is for If you are a game developer, game designer, technical artist, or solo developer with programming experience in Godot Engine and the GDScript programming language, this book is for you. Prior knowledge of programming concepts (e.g., functions, variables, algorithms) and an understanding of Godot's nodes and resources philosophy are essential to fully benefit from this book. Perfect for professionals looking to create solid, reusable, and reliable architecture that can adapt and grow with their creative vision. Table of Contents Understanding Object-Oriented Design - Learning the Four Fundamental Pillars - Creating SOLID Design Solutions - Favoring Composition Over Inheritance - Maintaining Global States with the Singleton Pattern - Decoupling Objects with the Observer Pattern - Spawning Game Objects with the Factory Pattern - Changing Object Behavior with the State Pattern - Designing Actors with the Command Pattern - Implementing AI with the Strategy Pattern - Creating a Power-Up System with the Decorator Pattern - Cross-Fading Transitions with the Service Locator Pattern - Improving Game Feel with the Event Queue Pattern “This book does something rare—it combines software engineering design patterns with game development principles while also teaching Godot Engine 4. Henrique does a great job explaining how to use these patterns to improve your code quality and efficiency, while implementing key features that can be easily seen in a variety of games in the industry. The knowledge you will acquire will help you progress in your game dev career or hobby and can be easily translated to other areas. Having followed Henrique’s work for a while, I had high expectations for this book— and I can say that my expectations were met.” Caio Souza Fonseca, Gameplay Programmer at Ubisoft Toronto “The author fills this gap for developers who have learned how to implement gameplay features in Godot, and may know some advanced topics, but are missing how to create extensible systems that tie it all together in a way that will scale through the many changes that can occur throughout the development of a game. After an overview of object-oriented design and the four fundamental pillars, the SOLID principles are covered in great detail before diving into several basic and advanced design patterns. The author does a great job explaining each pattern and demonstrating how to structure code for extensibility and maintainability. With this knowledge, you’ll be able to identify when these patterns may fit and how to implement them in any context. I highly recommend checking out this book.
