Overview of this book

Always dreamed of creating your own games? With the third edition of Beginning C++ Game Programming, you can turn that dream into reality! This beginner-friendly guide is updated and improved to include the latest features of VS 2022, SFML, and modern C++20 programming techniques. You'll get a fun introduction to game programming by building four fully playable games of increasing complexity. You'll build clones of popular games such as Timberman, Pong, a Zombie survival shooter, and an endless runner. 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 vertex arrays, directional sound (spatialization), OpenGL programmable shaders, spawning objects, and much more. You’ll dive deep into game mechanics and implement input handling, levelling up a character, and simple enemy AI. 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 a score and a message

Now we know enough about strings, SFML Text, and SFML Font to go about implementing the HUD. HUD stands for heads-up display and more formally refers to a cockpit instrumentation display that doesn’t require the pilot to look down. However, video game user interfaces, especially in-game interfaces, are often referred to as a HUD because they serve the same purpose as a cockpit HUD.

The next thing we need to do is add another #include directive to the top of the code file. As we have learned, the sstream class adds some useful functionality for combining strings and other variable types together into a single String.

Add the line of highlighted code.

#include <sstream>
#include <SFML/Graphics.hpp>
using namespace sf;
int main()
{

Next, we will set up our SFML Text objects: one to hold a message that we will vary to suit the state of the game and one that will hold the score and need to be regularly updated.

The next...
