Programming for Game Design: A Hands-On Guide with Godot

Create video game elements using the Godot game engine, gaining practical experience in programming and video game development. The Godot game engine uses a simplified programming language called GDScript, which closely resembles Python. By learning GDScript, you can focus more on learning the basics of programming.You’ll explore concepts such as variables and data structures variables used to store information about video game objects that can be manipulated using a keyboard or a mouse. You’ll also learn about user interface design, branching statements, and looping statements, enabling you to actively engage in programming and create your own interactive games.By the end of the book, you’ll have a solid understanding of how video game elements work and how the basic principles of programming work as well. By programming simple video game elements in the Godot game engine, you’ll learn both programming and the principles of 2D video game design.What You Will Learn Understand the basics of programming by creating simple video game elements in the Godot game engine. Explore variables and data structures to actively store and modify information about video game objects. Gain a deeper understanding of user interface design. Master simplified programming languages like GDScript.Who This Book Is ForAspiring programmers and game enthusiasts seeking an engaging introduction to programming through video game creation.
