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.

Defining a state

While it is a bit difficult to define correctly what a state actually is, and because that also depends on the implementation we choose to go with, we will try to pass our own idea of what states are and how they should behave.

We can look at a state as an independent screen in the gaming software, an object that encapsulates the logic and graphics of a determined group of functionality and information.

Nothing stops us from creating a state that behaves in any way we'd like; however, there are some usual guidelines into what belongs to the same state. Let's try to prove this shallowly by looking at the commercial games of our time. We will often see most games showing introduction videos, from the trailer of the game to company brand logos. We can look at each of these screens as states. In fact, having a VideoState that would simply playback a video and proceed to the next state would fit this model perfectly!

Then, we usually see a title screen, which is all about fancy...
