Pixel check sfml4/8/2023 ![]() ![]() ![]() At this point, the window is still open and we have to close it explicitly with the close function. In this case, we only care about the Event::Closed event, which is triggered when the user wants to close Whenever we get an event, we must check its type (window closed? key pressed? mouse moved? joystick connected?. The pollEvent function returns true if an event was pending, or false Note that we use a while loop so thatĪll pending events are processed in case there were several. Then, the first thing that we want to do inside our game loop is check for any events that occurred. Will have this kind of loop, sometimes called the main loop or game loop. Let's see how it works in detail.įirst, we added a loop that ensures that the application will be refreshed/updated until the window is closed. The above code will open a window, and terminate when the user closes it. "close requested" event: we close the window check all the window's events that were triggered since the last iteration of the loop run the program as long as the window is open ![]() Let's add some code to make this program a bit more interesting: Second, because there's no event handling - so even if you added an endless loop to this code, you would see a dead window, unable to be moved, First, because the program ends immediately. If you try to execute the code above with nothing in place of the ".", you will hardly see something. It takes the exact same arguments as the constructor. Video mode or title, you can use the create function instead. If you want to create the window after the construction of the sf::Window instance, or re-create it with a different There's also a fourth optional argument, which defines OpenGL specific options which are explained in the The default style, which is a shortcut for Titlebar | Resize | Close The window is shown in fullscreen mode this style cannot be combined with others, and requires a valid video mode The window can be resized and has a maximize button No decoration at all (useful for splash screens, for example) this style cannot be combined with others This constructor accepts a third optional argument: a style, which allows you to choose which decorations and features you want. The second argument is simply the title of the window. Don't hesitate to have a look at its documentation. The sf::VideoMode class has some interesting static functions to get the desktop resolution, or the list of valid video modes forįullscreen mode. The first argument, the video mode, defines the size of the window (the inner size, without the title bar and borders). A window can be created and opened directly upon construction: Windows in SFML are defined by the sf::Window class. However, the window management remains exactly the same so reading this tutorial is important in any case. Drawing stuff is beyond the scope of the sfml-window module: it is handled by the This tutorial only explains how to open and manage a window. Opening and managing a SFML window Introduction ![]()
