Beginning C++ Game Programming - Second Edition

By: John Horton

Overview of this book

The second edition of Beginning C++ Game Programming is updated and improved to include the latest features of Visual Studio 2019, SFML, and modern C++ programming techniques. With this book, you’ll get a fun introduction to game programming by building five fully playable games of increasing complexity. You’ll learn to build clones of popular games such as Timberman, Pong, a Zombie survival shooter, a coop puzzle platformer and Space Invaders. The book starts by covering the basics of programming. You’ll study key C++ topics, such as object-oriented programming (OOP) and C++ pointers, and get acquainted with the Standard Template Library (STL). The book helps you learn about collision detection techniques and game physics by building a Pong game. As you build games, you’ll also learn exciting game programming concepts such as particle effects, directional sound (spatialization), OpenGL programmable shaders, spawning objects, and much more. Finally, you’ll explore game design patterns to enhance your C++ game programming skills. By the end of the book, you’ll have gained the knowledge you need to build your own games with exciting features from scratch

Describing an object in the world

We have already added the level1.txt file in the world folder in Chapter 19, Game Programming Design Patterns – Starting the Space Invaders ++ Game. Let's discuss its uses, future intended uses, and its contents.

First, I would like to point out that a shooter game is not the best way to demonstrate how to describe a game world in a text file like this. The reason for this is that there are only a few types of game object and the most common one, invaders, are all lined up uniformly like soldiers on parade. They would actually be more efficiently described programmatically, perhaps in a nested for loop. However, the intention of this project was to show the ideas, rather than learn how to make a Space Invaders clone.

Take a look at the following text, which is a sample from the level1.txt file in the world folder:

[START OBJECT]
[NAME]invader[-NAME]
[COMPONENT]Standard Graphics[-COMPONENT]
[COMPONENT]Invader Update[-COMPONENT]...
