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>

Writing a thread-safe class


When dealing with multiple threads, writing a thread-safe class becomes an absolute must. If we do not write classes that are thread safe, there are many complications that may arise, such as deadlocks. We must also keep in mind that when we write a thread-safe class, there is no potential danger from data races and mutex.

Getting ready

For this recipe, you will need a Windows machine and an installed version Visual Studio.

How to do it…

In this recipe, we will see how easy it is to write a thread safe class in C++. Add a source file called Source.cpp and add the following code to it:

#include <thread>
#include <string>
#include <mutex>
#include <iostream>
#include <fstream>

using namespace std;

class DebugLogger
{
  std::mutex MU;
  ofstream f;
public:
  DebugLogger()
  {
    f.open("log.txt");
  }
  void ResourceSharingFunction(string id, int value)
  {
    std::lock_guard<std::mutex> guard(MU); //RAII
    f << "From" ...
