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 new lambda function of C++ 11


Lambda functions are the new addition to the C++ family. They can be described as anonymous functions.

Getting ready

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

How to do it…

To understand a lambda function let's have a look at the following code:

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;

int main()
{
  vector<int> numbers{ 4,8,9,9,77,8,11,2,7 };
  int b = 10;
  for_each(numbers.begin(), numbers.end(), [=](int y) mutable->void { if(y>b) cout<<  y<<endl;  });

  int a;
  cin >> a;

}

How it works…

Lambda functions are a new addition to the C++11 family. They are anonymous functions and can be very handy. They are generally passed as arguments to a function. The syntax of a lambda function is as follows:

  • [ capture-list ] ( params ) mutable(optional) exception attribute -> ret { body }

The mutable keyword is optional and is used...
