Sf::Glyph glyph = font.getGlyph(character, characterSize, bold) Ĭharacter is the UTF-32 code of the character whose glyph that you want to get. To do something meaningful with the font texture, you must get the texture coordinates of glyphs that are contained in it: Instead, they are rendered on the fly when you call the getGlyph function (see below).

There are so many characters (remember, more than 100000) that they can't allīe generated when you load the font. It is important to note that glyphs are added to the texture when they are requested. You can retrieve the texture which contains all the pre-rendered glyphs of a certain size:Ĭonst sf::Texture& texture = font.getTexture(characterSize) If sf::Text is too limited, or if you want to do something else with pre-rendered glyphs, sf::Font provides Indeed, fontsĭon't contain glyphs for all possible characters (there are more than 100000 in the Unicode standard!), and an Arabic font won't be able to display Japanese It may seem obvious, but you also have to make sure that the font that you use contains the characters that you want to draw. Note that the C++11 standard supports new character types and prefixes to build UTF-8, UTF-16 and UTF-32 string literals, but SFML doesn't support

We know that on most platforms, if not all, they'll produce Unicode strings, and SFML knows how to handle them correctly. In C++: the standard doesn't say anything about their size (16-bit? 32-bit?), nor about the encoding that they use (UTF-16? UTF-32?). It is this simple "L" prefix in front of the string that makes it work by telling the compiler to produce a wide string. To avoid having to bother with these encodings, there'sĪ simple solution: Use wide literal strings. Of the various encodings involved in the process of interpreting and drawing your text. Handling non-ASCII characters (such as accented European, Arabic, or Chinese characters) correctly can be tricky. How to avoid problems with non-ASCII characters? Sf::Sprite class and other SFML entities. The functions involved are the same as for the Text can also be transformed: They have a position, an orientation and a scale. inside the main loop, between window.clear() and window.display() tStyle(sf::Text::Bold | sf::Text::Underlined) tCharacterSize(24) // in pixels, not points! To draw text, you will be using the sf::Text class. Once your font is loaded, you can start drawing text.

The full list is available in the API documentation. You can also load a font file from memory ( loadFromMemory), or from a ) the working directory might sometimes be set to the project directory instead. However, when you launch your program from your IDE When you run the application from your desktop environment, the working directory is the executable folder. That any file path will be interpreted relative to) is what you think it is: If the message is unable to open file, make sure that the working directory (which is the directory First, check the error message that SFML prints to the standard The loadFromFile function can sometimes fail with no obvious reason. If you want to load aįont, you will need to include the font file with your application, just like every other resource (images, sounds. Firstly, because SFML requiresįile names, not font names, and secondly because SFML doesn't have magical access to your system's font folder. font.loadFromFile("Courier New") won't work. Note that SFML won't load your system fonts automatically, i.e. The most common way of loading a font is from a file on disk, which is done with the loadFromFile function. Program, you'll only have to make use of the first feature, loading the font, so let's focus on that first. visual characters) from it, and reading its attributes. Fonts are encapsulated in the sf::Font class, which provides three main features: loading a font, getting glyphs (i.e. If (!image.loadFromFile("test15.bmp")) įractal.Before drawing any text, you need to have an available font, just like any other program that prints text.
