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

Preparing the player (and other sprites)

Let's add the code for the player's sprite as well as a few more sprites and textures at the same time. The following, quite large, block of code also adds a gravestone sprite for when the player gets squashed, an axe sprite to chop with, and a log sprite that can whiz away each time the player chops.

Notice that, after the spritePlayer object, we declare a side variable, playerSide, to keep track of where the player is currently standing. Furthermore, we add some extra variables for the spriteLog object, including logSpeedX, logSpeedY, and logActive, to store how fast the log will move and whether it is currently moving. The spriteAxe also has two related float constant variables to remember where the ideal pixel position is on both the left and the right.

Add the following block of code just before the while(window.isOpen()) code, like we have done so often before. Note that all of the code in the following block is new, not...
