Example 61 with BitmapFont

use of com.badlogic.gdx.graphics.g2d.BitmapFont in project libgdx by libgdx.

the class FreeTypeAtlasTest method createFonts.

    // texture atlas.

    // 1. Create a new PixmapPacker big enough to fit all your desired glyphs
    // 2. Create a new FreeTypeFontGenerator for each TTF file (i.e. font styles/families)
    // 3. For each size and style, call generator.generateFont() with the packer set on the parameter
    // 4. Generate the texture atlas using packer.generateTextureAtlas or packer.updateTextureAtlas.
    // 5. Dispose of the atlas upon application exit or when you are done using the fonts
