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.

Low-level rendering

Besides the high-level convenience classes sf::Sprite, sf::Text and sf::Shape, SFML provides a low-level graphics API which is more complicated to use, but allows more flexibility. In the next section, we are going to look behind the scenes of rendering and discuss corresponding techniques as they are implemented in SFML.

OpenGL and graphics cards

The graphics card architecture consists of many components. Notable are the graphics processing unit (GPU), which performs computations on the graphics card, and the video memory, which stores data such as textures. In contrast to their counterparts CPU and RAM, graphics cards' components are highly optimized to process 2D and 3D graphics.

SFML is built on top of the Open Graphics Library (OpenGL). OpenGL is, like DirectX, a specification of an interface to the graphics card. Operating systems provide an API written in C that allows applications to access graphic card functionality. Newer graphics cards support higher OpenGL versions...
