How to draw smooth text in libgdx?

Question

I try to draw simple text in my android game on libgdx, but it's look sharp. How to make text look smooth in different resolutions? My Code:

private BitmapFont font;  font = new BitmapFont();  font.scale((ppuX*0.02f));  font.draw(spb, "Score:", width/2-ppuX*2f, height-0.5f*ppuY); 

Answer 1

font.getRegion().getTexture().setFilter(TextureFilter.Linear, TextureFilter.Linear); 

This gets the texture used in a BitmapFont and changes its filtering to bilinear, allowing higher resulting image quality while both up- and downscaling it at the cost of slightly slower (the difference is usually not noticeable) GPU rendering.

Answer 2

One solution is to use the FreeType extension to libgdx, as described here. This allows you to generate a bitmap font on the fly from a .ttf font. Typically you would do this at startup time once you know the target resolution.

Here's an example:

int viewportHeight; BitmapFont titleFont; BitmapFont textFont;  private void createFonts() {     FileHandle fontFile = Gdx.files.internal("data/Roboto-Bold.ttf");     FreeTypeFontGenerator generator = new FreeTypeFontGenerator(fontFile);     FreeTypeFontParameter parameter = new FreeTypeFontParameter();     parameter.size = 12;     textFont = generator.generateFont(parameter);     parameter.size = 24;     titleFont = generator.generateFont(parameter);     generator.dispose(); }
