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.
