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>

Avoiding deadlocks


When two or more tasks want to use the same resource, we have a race condition. Until one task finishes using the resource, the other task cannot get access to it. This is known as a deadlock, and we must avoid deadlocks at all costs. For example, resource Collision and resource Audio are used by process Locomotion and process Bullet:

  • Locomotion starts to use Collision

  • Locomotion and Bullet try to start using Audio

  • Bullet "wins" and gets Audio first

  • Now Bullet needs to use Collision

  • Collision is locked by Locomotion, which is waiting for Bullet

Getting ready

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

How to do it…

In this recipe, we will find out how easy it is to avoid deadlocks:

#include <thread>
#include <string>
#include <iostream>

using namespace std;

void Physics()
{
  for (int i = 0; i > -100; i--)
    cout << "From Thread 1: " << i << endl;

}

int main()
{
  std::thread t1(Physics...
