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.

Chapter 3. Forge of the Gods – Shaping Our World

In the previous chapter, we have covered loading, managing, and releasing of external resources. To sum up, we have investigated mechanisms to ensure that textures, fonts, or sounds are ready to be used as soon as we need them. This chapter attempts to bring knowledge around a few key topics:

  • Entity systems in concept and practice

  • The viewable area of our world and scrolling

  • Tree-based scene graphs, rendering and updating of many entities

  • Composition of all elements to shape the world

When writing a game, we invariably find the need to conceptualize our vision of the game into actual data structures. In other words, it is extremely important to have a clear idea of the scope of our vision. The world in our mind doesn't even have to scale remotely to what we consider our real world; it is a product of our own creation. It is well within our power, as game developers, to forge the whole world as a simple board game table, or an ant farm, or even...
