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>

Using the strategy pattern


The strategy design pattern is a very smart way of designing code. In games, this is mostly used for the AI component. In this pattern, we define a large number of algorithms and have all of them from a common interface signature. Then at runtime, we can change the clients of the algorithms. So in effect, the algorithms are independent of the clients.

Getting ready

To work through this recipe, you will need a machine running Windows. You also need to have a working copy of Visual Studio installed on your Windows machine. No other prerequisites are required.

How to do it…

In this recipe, we will find out how easy it is to implement the strategy pattern:

  1. Open Visual Studio.

  2. Create a new C++ project.

  3. Select a Win32 console application.

  4. Add a Source.cpp file.

  5. Add the following lines of code to it:

    #include <iostream>
    #include <conio.h>
    
    using namespace std;
    
    
    class SpecialPower
    {
    public:
      virtual void power() = 0;
    };
    
    class Fire : public SpecialPower
    {
    public:
    ...
