Beginning C++ Game Programming

Overview of this book

This book is all about offering you a fun introduction to the world of game programming, C++, and the OpenGL-powered SFML using three fun, fully-playable games. These games are an addictive frantic two-button tapper, a multi-level zombie survival shooter, and a split-screen multiplayer puzzle-platformer. We will start with the very basics of programming, such as variables, loops, and conditions and you will become more skillful with each game as you move through the key C++ topics, such as OOP (Object-Orientated Programming), C++ pointers, and an introduction to the Standard Template Library. While building these games, you will also learn exciting game programming concepts like particle effects, directional sound (spatialization), OpenGL programmable Shaders, spawning thousands of objects, and more.

Before you go...

Building the Thomas and Bob classes


Now we get to use inheritance for real. We will build a class for Thomas and a class for Bob. They will both inherit from the PlayableCharacter class we just coded. They will then have all the functionality of the PlayableCharacter class, including direct access to its protected variables. We will also add the definition for the pure virtual function handleInput. You will notice that the handleInput functions for Thomas and Bob will be different.

Coding Thomas.h

Right-click Header Files in the Solution Explorer and select Add | New Item.... In the Add New Item window, highlight (by left-clicking) Header File (.h) and then in the Name field, type Thomas.h. Finally, click the Add button. We are now ready to code the header file for the Thomas class.

Now add this code to the Thomas.h class:

#pragma once 
#include "PlayableCharacter.h" 
 
class Thomas : public PlayableCharacter 
{ 
public: 
   // A constructor specific to Thomas ...
