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.

C++ References, Sprite Sheets, and Vertex Arrays

In Chapter 4, Loops, Arrays, Switch, Enumerations, and Functions – Implementing Game Mechanics, we talked about scope. This is the concept that variables declared in a function or inner block of code only have scope (that is, can be seen or used) in that function or block. Using only the C++ knowledge we have currently can cause a problem. What do we do if we need to work on a few complex objects that are needed in the main function? This could imply that all the code must be in the main function.

In this chapter, we will explore C++ references, which allow us to work on variables and objects that are otherwise out of scope. In addition to this, these references will help us avoid having to pass large objects between functions, which is a slow process. It is slow because each time we do this, a copy of the variable or object must be made.

Armed with this new knowledge of references, we will look at the SFML VertexArray...
