Sure you can close it but it looks weird, the previous contents of the screen are mapped to it and look super weird. Now if you run the program you get a weird looking window (as shown below). Note that closing the window doesn’t terminate the program! But since our window is now closed the isOpen method will now return false and we will return out of what’s called – the main loop of the program! It updates event with the next event in the queue and then in the event loop we check if the event was not sf::Event::Closed which is just a cryptic way of asking SFML did the user X.ed the window? By default nothing happens when the user hits the close button, so we override this behaviour by closing the window. What pollEvent method basically does is it checks if the the event queue is not empty. We create an event object which then we later pass in window.pollEvent. Now inside of this loop we check for events. Turns out the Window class provides a method isOpen which returns whether or not is a window open. We are basically running a loop as long as the window is open. In the second statement we have some new logic.And also note that we are using ‘sf’ namespace as all the SFML classes and Methods are defined under this class. And by the way, VideoMode is simply a type that defines the dimensions of the window (and bits per pixel but we don’t need that now). In this, we pass the videomode and title of the window. The first statement creates a window object using the Window constructor.
Windows users can download SFML from this link and follow the guide to install it.īefore running the program let’s understand what’s going on! Setting up Environmentīefore we program in SFML we must set up the environment! Hopefully, it’s not a much of a headache especially not if you are in Linux! Debian Linux users (and any other flavour of Linux with apt/apt-get) can install SFML with the following command:. Since OpenGL can’t create a window, 3D graphics programmers use SFML (at least most of the time) for the task. And even though SFML doesn’t support 3D rendering yet it is used for context creation. SFML is used heavily in making games and even game engines. It’s so fast that you’d be running the application at several thousand frames per second. Well, how simple is it? So simple that you could get a snake game running in less than 15 minutes. It stands for Simple and Fast Multimedia Library. It does not just let you use hardware-accelerated 2D Graphics with OpenGL but also has a variety of methods related to different types of media such as fonts, audio, etc. Simply put SFML is a multimedia library for C++ with bindings available for other languages such as Python, Rust, etc. So in this very quick tutorial, let’s learn about the basics of the mighty OpenGL-powered SFML Graphics Library.
