SFML Game Development By Example

By: Raimondas Pupius

Overview of this book

Simple and Fast Multimedia Library (SFML) is a simple interface comprising five modules, namely, the audio, graphics, network, system, and window modules, which help to develop cross-platform media applications. By utilizing the SFML library, you are provided with the ability to craft games quickly and easily, without going through an extensive learning curve. This effectively serves as a confidence booster, as well as a way to delve into the game development process itself, before having to worry about more advanced topics such as “rendering pipelines” or “shaders.” With just an investment of moderate C++ knowledge, this book will guide you all the way through the journey of game development. The book starts by building a clone of the classical snake game where you will learn how to open a window and render a basic sprite, write well-structured code to implement the design of the game, and use the AABB bounding box collision concept. The next game is a simple platformer with enemies, obstacles and a few different stages. Here, we will be creating states that will provide custom application flow and explore the most common yet often overlooked design patterns used in game development. Last but not the least, we will create a small RPG game where we will be using common game design patterns, multiple GUI. elements, advanced graphical features, and sounds and music features. We will also be implementing networking features that will allow other players to join and play together. By the end of the book, you will be an expert in using the SFML library to its full potential.

Using the SFML views


Up until this point, we have only dealt with code that renders things within the boundaries of the window that's open. There hasn't been an instance where we needed the screen to move yet, which would be fine if we lived in the early days of the 80s, but games even a decade after that time were a lot more advanced. Take, for example, Super Mario Brothers, a classic side-scroller. Its genre alone pinpoints what our first game didn't have: scrolling. If the scrolling effect or any kind of movement, resizing or rotation of the screen is desirable, using the sf::View is necessary.

What is sf::View? It's a rectangle. That's it. If you have ever held your fingers in a rectangle shape to "frame" the world you're observing, you have created a view with your hands. By moving it, you are essentially moving through the scene beyond the cut-off point of the window. If you're still not "getting the picture," here's an illustration to lead you in the right direction:

The sf::View is...
