Overview of this book

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. 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. 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++.

Using bit shift operators in an enum

As we have seen before in previous recipes, an enum is used to represent a collection of states. All the states are given an integer value by default, starting at 0. However, we could specify a different integer value as well. More interestingly, we could use bit shift operators to club some of the states, easily set them to be active or inactive, and do other tricks with them.

Getting ready

To work through this recipe, you will need a machine running Windows with an installed Visual Studio.

How to do it…

In this recipe, we will see how easy it is to write bit shift operators in an enum:

#include <iostream>

enum Flags
{
  FLAG1 = (1 << 0),
  FLAG2 = (1 << 1),
  FLAG3 = (1 << 2)
};

int main()
{

  int flags = FLAG1 | FLAG2;

  if (flags&FLAG1)
  {
    //Do Something
  }
  if (flags&FLAG2)
  {
    //Do Something
  }


  return 0;
}

How it works…

In the above example, we have three flag states in the enum. They are represented...
