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

Adding the WorldState.h file

Create a new header file in the Header Files/Engine filter called WorldState.h and add the following code:

#pragma once
class WorldState
{
public:
    static const int WORLD_WIDTH = 100;
    static int WORLD_HEIGHT;
    static int SCORE;
    static int LIVES;
    static int NUM_INVADERS_AT_START;
    static int NUM_INVADERS;
    static int WAVE_NUMBER;
};

These variables are public and static. As a result, they will be accessible throughout the project and are guaranteed to have only a single instance.
