Preface
Godot is an open source game engine that enables developers to create interesting and unique projects, mainly video games. While Godot has a built-in scripting language called GDScript, C# has, over time, gained more support, especially in Godot 4.
Dedicated to Godot 4 and C#, this book guides you through creating a 3D project in Godot, using C# as the programming language from start to finish. In writing this book, I wanted to share my personal experience with Godot alongside my professional experience as a C# developer.
In this book, we will first discuss the relationship between the two and then spend time setting up our development environment. After that, we'll look at how best to organize our project to keep the assets and scripts as orderly as possible.
Once we have our development environment configured, we'll explore the various components to create a 3D action game. Some of those components will include a player controller, animations, user interface, sound effects, and pathfinding. Within each section, we'll discover more features built into Godot's engine and how best to leverage those features in our project.
As we wrap up a vertical slice of our 3D action game, we'll look at third-party plugins and applications that can improve our development life cycle. The last step for our project will be to export the game and publish it on the itch.io platform.
Finally, we will explore outside the game engine into the Godot community and see what other resources are available to Godot developers, such as C#-specific communities and other notable creators in the space.
Most of the features included in this book have been updated to Godot 4.4, and although the UI may change, the idea behind the usage can still be applied to future versions of Godot.
Who this book is for
This book is for developers and creators seeking more knowledge about the Godot Engine, specifically using Godot with C#. Experience with an object-oriented programming language is required to get the most out of this book.
What this book covers
Chapter 1, Introducing Godot 4, introduces the Godot Engine, including what makes it a viable game engine choice, and specific features that make it a worthwhile choice in game development projects.
Chapter 2, Understanding How C# Works in Godot, walks through the relationship between the Godot Engine and C#, as well as setting up a development environment to work fluidly between the two.
Chapter 3, Organizing and Setting Up a Project for a 3D Action Game, explores two different schools of thought when it comes to organizing a project for the rest of the book.
Chapter 4, Creating Our Player Controller, focuses on the player controller, creating animations, and keying controls to player actions.
Chapter 5, Creating Our Game World, illustrates the importance of level design, how to import a variety of assets, and how to add collision meshes to them for use in a level.
Chapter 6, Developing and Managing the User Interface, spends time creating a main menu to access the level and adding some simple animations to the UI.
Chapter 7, Adding Sound Effects and Music, explores sound buses and how to use them for either sound effects or music, and brings them together for UI, player actions, and level music.
Chapter 8, Adding Navigation and Pathfinding, implements navigation and pathfinding for a non-player character to autonomously move throughout the level.
Chapter 9, Setting Up Lighting in Godot, discusses lighting in a variety of ways, specifically for global illumination and interior lighting.
Chapter 10, Understanding Accessibility and Additional Features, reviews the project so far and highlights accessibility components, expanding the UI to accommodate a Settings screen.
Chapter 11, Exporting Your Game, walks through the process of exporting the project to multiple platforms and how it can be played by people outside the project.
Chapter 12, Contributing to Godot and Additional Resources, dives into how to contribute to the engine and provides feedback on issues while also highlighting third-party plugins to utilize in the project.
Chapter 13, Next Steps as a Godot Developer, explores the wider Godot community outside the engine, specifically C#-focused spaces.
Appendix: Transitioning from Godot 3 to Godot 4, provides insight on whether creators should upgrade to Godot 4, the benefits of doing so, and the process to upgrade.
