Overview of this book

Game development comprises the combination of many different aspects such as game logics, graphics, audio, user input, physics and much more. SFML is an Open Source C++ library designed to make game development more accessible, exposing multimedia components to the user through a simple, yet powerful interface. If you are a C++ programmer with a stack of ideas in your head and seeking a platform for implementation, your search ends here.Starting with nothing more than a blank screen, SFML Game Development will provide you with all the guidance you need to create your first fully featured 2D game using SFML 2.0. By the end, you'll have learned the basic principles of game development, including advanced topics such as how to network your game, how to utilize particle systems and much more.SFML Game Development starts with an overview of windows, graphics, and user inputs. After this brief introduction, you will start to get to grips with SFML by building up a world of different game objects, and implementing more and more gameplay features. Eventually, you'll be handling advanced visual effects, audio effects and network programming like an old pro. New concepts are discussed, while the code steadily develops.SFML Game Development will get you started with animations, particle effects and shaders. As well as these fundamental game aspects, we're also covering network programming to the extent where you'll be able to support the game running from two different machines. The most important part, the gameplay implementation with enemies and missiles, will make up the core of our top-scrolling airplane shoot' em-up game!You will learn everything you need in SFML Game Development in order to start with game development and come closer to creating your own game.

Post effects and shaders


You know those big budget games with dedicated graphics programmers on them? One of the techniques they use is something called post rendering or post effects. It's an effect that is applied after the scene has already been rendered. Using that data, we perform whatever visual effect we want on it. One way to create effects is using shaders, which we will delve into later.

The first thing to cover is how to perform a post effect, how it works, and then we will actually create an effect called bloom using shaders.

Fullscreen post effects

Well, the effect has to be applied to the whole screen, otherwise it is pretty useless. That is why we define a specific PostEffect class in order to make this a bit easier.

class PostEffect
{
    public:
        virtual            ~PostEffect();
        virtual void       apply(const sf::RenderTexture& input,sf::RenderTarget& output) = 0;

        static bool        isSupported();

    protected:
        static void       ...
