Beschreibung

Jumping into Godot 4 as a beginner can be overwhelming. You’re wrestling with a new interface, trying to wrap your head around how nodes and scenes work, and learning GDScript all at once. After years of teaching game development and creating YouTube tutorials, Robert Henning knows exactly where you’re likely to have those “wait, what?” moments. He’s built this guide to systematically address those challenges head-on, breaking down complex concepts into digestible steps.
You’ll start by setting up Godot 4 and understanding its interface and tools. Then, you’ll dive into nodes and scenes, Godot’s way of organizing everything, which sounds intimidating but is actually quite intuitive. From there, you’ll explore both 2D and 3D game creation, adding key elements such as players, enemies, collectibles, and lighting effects that make your game pop visually. You’ll also get hands-on with Godot’s scripting language, GDScript, to bring your game ideas to life.
By the end of this Godot 4 book, you’ll have the skills to build complete 2D and 3D games from scratch, covering everything from level design and game state management to score tracking and more. Whether you’re just getting started or are ready to level up, this book will help you turn your ideas into fully playable games.

Foreword

Creating games has never been this accessible, thanks in large part to powerful yet approachable engines like Godot. However, diving into engines like Godot—while user-friendly—still involves mastering a diverse set of skills, from the obvious ones like programming and math to the less obvious ones like software architecture and game design. Even if you already know the inner workings of a game engine, transitioning to another can be tedious.

This book, written by professional game development tutor Robert Henning, addresses exactly this issue and eases readers into the vast field of game development. The cultivation of new skills will be much easier through Robert’s teaching methods. Moreover, you will even enjoy the process, as the book includes exercises and projects that offer early wins to boost your motivation.

Although I have never met Robert in person, he helped me become a professional game developer in a very direct way—by creating tutorials and Godot Engine-related content on YouTube that both aided and motivated me. At the time of writing this foreword, his channel has over 50,000 subscribers, which is a testament to the usefulness of his videos and his prolific will to help people get started with game development in Godot.

Reading through these pages and doing the exercises transports me back to when I was a beginner—a blank slate—and makes me excited to try out new things. Because if there is one thing that is most important, it is this: always keep a beginner’s mindset and experiment. Every time you learn something or do an exercise, take it to its limits. Change a value here and there until it breaks, and then take a step back. It’s only when we leave the path that we see clearly why the path is there in the first place.

So, I will hold you no longer. Go explore the path laid out by Robert in this excellent book. Look at it as an adventure. Experiment freely, explore the possibilities, and find your own style. You won’t regret it.
