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.

Re-implementing the main menu


In order to demonstrate how much easier it is building interactivity in this way, let's re-construct the main menu, starting by creating its .interface file:

Interface MainMenu MainMenu.style 0 0 Immovable NoTitle "Main menu"
Element Label Title 100 0 MainMenuTitle.style "Main menu:"
Element Label Play 0 32 MainMenuLabel.style "PLAY"
Element Label Credits 0 68 MainMenuLabel.style "CREDITS"
Element Label Quit 0 104 MainMenuLabel.style "EXIT"

The interface is set to have zero padding on both axes, be immovable, and have no title bar. All three buttons in this interface, as well as its title, can be represented by labels with different styles. Speaking of which, let's take a look at the style of our main menu interface:

State Neutral
Size 300 150
TextSize 12
Font Main
/State

As you can see, it only defines the most basic attributes and does not aim to be visually responsive by itself. The button label style, however, is a little different:

State Neutral
Size 300 32...
