Chapter 22: Using Game Objects and Building a Game

This chapter is the final stage of the Space Invaders ++ project. We will learn how to receive input from a gamepad using SFML to do all the hard work and we will also code a class that will handle communication between the invaders and the GameScreen class, as well as the player and the GameScreen class. The class will allow the player and the invaders to spawn bullets, but the exact same technique could be used for any kind of communication that you need between different parts of your own game, so it is useful to know. The final part of the game (as usual) will be the collision detection and the logic of the game itself. Once Space Invaders ++ is up and running, we will learn how to use the Visual Studio debugger, which will be invaluable when you are designing your own logic because it allows you to step through your code a line at a time and see the value of variables. It is also a useful tool for studying the execution flow of...
