C++ Game Development Cookbook

By: Druhin Mukherjee

Overview of this book

<p>C++ is one of the preferred languages for game development as it supports a variety of coding styles that provides low-level access to the system. C++ is still used as a preferred game programming language by many as it gives game programmers control of the entire architecture, including memory patterns and usage. However, there is little information available on how to harness the advanced features of C++ to build robust games.</p> <p>This book will teach you techniques to develop logic and game code using C++. The primary goal of this book is to teach you to create high-quality games using C++ game programming scripts and techniques, regardless of the library or game engine you use. It will show you how to make use of the object-oriented capabilities of C++ so you can write well-structured and powerful games of any genre. The book also explores important areas such as physics programming and audio programming, and gives you other useful tips and tricks to improve your code.</p> <p>By the end of this book, you will be competent in game programming using C++, and will be able to develop your own games in C++.</p>

Use operator overloading to reuse operators


There are lots of operators that are provided for us by C++. However, sometimes we need to overload these operators so that we can use them on data structures that we create ourselves. Of course, we can overload the operators to change the meaning as well. For example, we can change + (plus) to behave like - (minus), but this is not recommended as this usually does not serve any purpose or help us in any way. Also, it may confuse other programmers who are using the same code base.

Getting ready

You need to have a working copy of Visual Studio installed on your Windows machine.

How to do it…

In this recipe, we will see how we can overload an operator and which operators are allowed to be overloaded in C++.

  1. Open Visual Studio.

  2. Create a new C++ project.

  3. Select Win32 Console Application.

  4. Add a source file called Source.cpp, vector3.h, and vector3.cpp.

  5. Add the following lines of code to Source.cpp:

    #include "vector3.h"
    #include <conio.h>
    #include "vld.h...
