Introduction

This is a sequel to the original MonoGame Mastery book. If you haven’t read the original, I highly recommend checking it out before you get into this one. This book has more intermediate techniques, ranging from putting different languages into a game to setting up for debugging. At the end, we will also be talking about notable libraries that will help make development easier in MonoGame.

By the end of the book, you will have a better knowledge of programming in MonoGame and utilizing the Content Pipeline tool for more efficiency. In the first half of the book, you will be looking at the previous 2D shooter and improving it with a level editor. In the second half, you will be making a small 2D platformer that utilizes a texture shader and particle engine. You will also look at notable libraries (along with their GitHub links) to see their source code and what they do. We hope you’ll find this book useful for your programming endeavors.

Acknowledgments

I have to thank the people on the MonoGame forums and Discord servers for providing their knowledge and help with this book. I wouldn’t have been able to do it without their help.

Thanks also to my close friends and family who kept pushing me on to finish. I don’t think I would have pulled through without their support.

About the Authors
Louis Salin

has been a developer for more than 15 years in a wide variety of fields, developing on Windows in the early days in C, C++, and eventually C#. He also worked as a developer on Linux-based web applications using different scripting languages such as Ruby and Python. His early love for coding comes from all the time he spent as a kid copying video games written in Basic from books borrowed from the library. He wrote his first game in high school and took many classes in computer graphics.

is a self-taught game developer with a few years of development experience under his belt. Morrar spent his days as a young kid hacking his Nintendo consoles with homebrew software. In his early adult years, he delved into languages mostly found in the family of C programming, such as C# and C++. He is a freelance technology writer who reviews games and writes tutorials on MonoGame. He is currently working on his own independent project in the framework as well.
