Beginning C++ Game Programming

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.

Arrays


If a variable is a box in which we can store a value of a specific type, like int, float, or char, then we can think of an array as a whole row of boxes. The row of boxes can be of almost any size and type, including objects of classes. However, all the boxes must be of the same type.

Tip

The limitation of having to use the same type in each box can be circumvented, to an extent, once we learn some more advanced C++ in the final project.

This array sounds like it could have been useful for our clouds from Chapter 2: Variables, Operators, and Decisions - Animating Sprites. So how do we go about creating and using an array?

Declaring an array

We can declare an array of int type variables like this:

int someInts[10]; 

Now we have an array called someInts that can store ten int values. At the moment, however, it is empty.

Initializing the elements of an array

To add values into the elements of an array, we can use the type of syntax we are already familiar with, combined with some new syntax...
