Are you ready to build a game? GameMaker Studio is a professional development engine used to build games like Hyper Light Drifter, Death's Gambit, Risk of Rain, Valdis Story, Hotline Miami, and many more. These great games show the power of this tool but the very best part of GameMaker Studio is that it's one of the best places for new indie game developers to begin their journey. It is where I started and I have loved every second of it. Helping you on this journey is my goal with this book. With this book you will learn about GameMaker Language Lexical Structure, Data Types and Values, Variables, Arrays and Data Structures, Expressions and Operators, Statements, Scripts, Objects, Events, Game Audio, Development Patterns and Tricks, Surfaces and Particles, HUD and GUI Layer, Box2D Physics, Online Multiplayer, and Artificial Intelligence.
