Examples of com.badlogic.gdx.graphics.g2d.BitmapFont

com.badlogic.gdx.graphics.g2d.BitmapFont
Renders bitmap fonts. The font consists of 2 files: an image file or {@link TextureRegion} containing the glyphs and a file inthe AngleCode BMFont text format that describes where each glyph is on the image. Currently only a single image of glyphs is supported.

Text is drawn using a {@link SpriteBatch}. Text can be cached in a {@link BitmapFontCache} for faster rendering of static text,which saves needing to compute the location of each glyph each frame.

* The texture for a BitmapFont loaded from a file is managed. {@link #dispose()} must be called to free the texture when nolonger needed. A BitmapFont loaded using a {@link TextureRegion} is managed if the region's texture is managed. Disposing theBitmapFont disposes the region's texture, which may not be desirable if the texture is still being used elsewhere.

The code is based on Matthias Mann's TWL BitmapFont class. Thanks for sharing, Matthias! :) @author Nathan Sweet @author Matthias Mann
