Overview of this book

This book is all about offering you a fun introduction to the world of game programming, C++, and the OpenGL-powered SFML using three fun, fully-playable games. These games are an addictive frantic two-button tapper, a multi-level zombie survival shooter, and a split-screen multiplayer puzzle-platformer. We will start with the very basics of programming, such as variables, loops, and conditions and you will become more skillful with each game as you move through the key C++ topics, such as OOP (Object-Orientated Programming), C++ pointers, and an introduction to the Standard Template Library. While building these games, you will also learn exciting game programming concepts like particle effects, directional sound (spatialization), OpenGL programmable Shaders, spawning thousands of objects, and more.

Giving the player a crosshair


Adding a crosshair is easy and only requires one new concept. Add the highlighted code and then we can run through it:

// 100 bullets should do 
Bullet bullets[100]; 
int currentBullet = 0; 
int bulletsSpare = 24; 
int bulletsInClip = 6; 
int clipSize = 6; 
float fireRate = 1; 
// When was the fire button last pressed? 
Time lastPressed; 
 
// Hide the mouse pointer and replace it with crosshair
window.setMouseCursorVisible(true);
Sprite spriteCrosshair;
Texture textureCrosshair =
    TextureHolder::GetTexture("graphics/crosshair.png");

spriteCrosshair.setTexture(textureCrosshair);
spriteCrosshair.setOrigin(25, 25); 
// The main game loop 
while (window.isOpen())

First we call the setMouseCursorVisible function on our window object. We then load a Texture, declare a Sprite, and initialize it in the usual way. Furthermore, we set the sprite's origin to its center to...
