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 resources


In game development, the term resource denotes an external component, which the application loads during runtime. Another often-used term for a resource is asset.

Mostly, resources are heavyweight multimedia items, such as images, music themes, or fonts. "Heavyweight" refers to the fact that those objects occupy a lot of memory, and that operations on them, especially copying, perform slowly. This affects the way we use them in our application, as we try to restrict slow operations on them to a minimum.

Non-multimedia items such as scripts that describe the in-game world, menu content, or artificial intelligence are also considered resources. Configuration files containing user settings such as the screen resolution and the music volume are good examples of resources as well. However, when we mention resources in the book, we mostly refer to multimedia resources.

Resources are usually loaded from a file on the hard disk. Although being the most common approach, it is not...
