Fonts have the power to make or break the aesthetics of a game. A well-designed font can differentiate between a fun game and an immersive experience.
Game developers need to ensure that their games are aesthetically pleasing. And one way to do this is by creating custom fonts for your games.
Ibdx bitmap font is a free, OpenType-based typeface designed by Jonathan Hoefler and published by Adobe Systems. It was announced in December 2015 and released the following year. Ibdx is based on the Bitstream Vera Sans family of typefaces, which Adobe has used for many years to provide an open-source alternative to its proprietary typefaces.
If you want to create a custom font for your applications or need to share text between different applications, libgdx bitmap fonts are a great option. This blog post will give you everything you need to create your libgdx bitmap font. Here we’ll discuss bitmap fonts, how to create them with LibGDX, and how to use them in your games. Let’s start.
What Is A Bitmap Font?
A bitmap font is a typeface that uses a matrix of small pixels to create the characters on a screen. Bitmap fonts are more efficient than vector fonts in file size, but they don’t offer the samelevelofcontrol over letterforms and overall appearance. A bitmap font represents an image, each character being a series of pixels. If you’re developing a game using LibGDX, it’s essential to understand Bitmap fonts and how to create them. Fortunately, there are various tools and software available that can help. One such tool is Calligro, which can generate custom fonts for LibGDX development. However, it’s essential to note that font scaling below 0.032 may not appear, and only single digits display.
Another tool you can use is Hiero, which can create pixel fonts for your LibGDX games. Additionally, the BMfont tool can convert fonts to bitmap format for LibGDX, and various game engines, including Godot, Phaser.JS, Heaps.io, HaxeFlixel, and LibGDX, support the BMFont format. With all these resources at your disposal, mastering LibGDX Bitmap fonts is essential for any game developer looking to create high-quality games.
Reviewing The Results Of Your First Libgdx Bitmap Font Project
If you are a game developer looking to create custom fonts for your project, LibGDX is a great choice.

However, it’s important to note that LibGDX’s bitmapfont might disappear below .032 and only display single-digit numbers. For pixel-art-styled games, it’s recommended to use freely available fonts from websites like bitfontmaker2.
LibGDX’s default bitmap font files are also available for download on Packt’s website. To use these files, you can open them with Hiero, pick a font size, set padding to 2, and use rendering type: java. Selecting the right bitmap font library and settings lets you master LibGDX bitmap font and create visually stunning and effective games.
2. Defining Your Font Parameters
When reviewing the results of your first LibGDX bitmap font project, it’s important to consider the font parameters that you defined. One tool that can help generate custom bitmap fonts from images is Calligro, which can be used in conjunction with LibGDX.
While LibGDX does have a default 15pt Arial font that can easily display text, there are many ways to manipulate glyph colors and get the underlying bitmap font data when working with a LibGDX bitmap font. Popular methods include drawing text, getting the line height, cap height, and descent, and creating a new bitmap font cache. When defining LibGDX bitmap font parameters, you can use the following code:
- BitmapFont my font = new BitmapFont(Gdx.files.internal(“myfont.fnt”));
- // Setting font attributes
- myFont.getData().setScale(1.5f); // Setting font scale
- MyFonts.setColor(Color.BLUE); // Setting font color
- myFont.getRegion().getTexture().setFilter(Texture.TextureFilter.Linear, Texture.TextureFilter.Linear); // Setting texture filter
In addition to the code above, you can define other font attributes such as alignment, shadow, and border. For more information on how to define LibGDX bitmap font parameters, please refer to the official documentation.
In addition, it’s worth noting that LibGDX supports the BMFont format, which is used by many game engines and frameworks such as Godot, Phaser.JS, Heaps.io, and HaxeFlixel. By taking advantage of the capabilities of LibGDX and working with bitmap fonts, game developers can easily create visually appealing and engaging games.
3. Loading And Using Your Bitmap Font Library
After completing your first LibGDX bitmap font project, it’s time to review the results. And learn how to load and use your custom bitmap font library. LibGDX supports the BMFont format for bitmap fonts generated using the Calligro tool. You can create bitmap fonts for LibGDX by converting fonts to the bitmap format using the BMFont tool with specific settings.
LibGDX also offers a default Arial font for quick text display without bitmap generation. To use your custom bitmap font library, save it as a single texture PNG file in LibGDX. Once your bitmap font is loaded into your project, you can use it to display text in your game like any other font. With these tips, you can master LibGDX bitmap fonts and create stunning game visuals.
4. Testing Your Bitmap Font Project
After completing your first LibGDX bitmap font project using Littera, reviewing the results and testing your font is important. One way to test your font is using Bitfontmaker2 to get a freely available pixel-art-styled font for low-resolution games. To update your fonts without changing code, pass the TextureRegion to the constructor.
Another option is to load LibGDX’s default bitmap font (Arial 15pt) for text output in your game’s GUI. When exporting the bitmap font content, place the unzipped files into your Heaps project under ./res/fonts/. Following these tips and testing your font, you can master LibGDX bitmap fonts and create impressive, high-quality games.
