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:

Answer 1

My Solution for smooth text with Libgdx

I use BitmapFont and I generate 3 different size same fonts using Hiero tool example Arial 16 , Arial 32, Arial 64

I put them in my assets file and use (load) only one of them depeding on the size of screen

if(Gdx.graphics.getWidth() < (480*3)/2)
        {
            textGametFont = BitmapFont(Gdx.files.internal(nameFont+16+".fnt"),
                    Gdx.files.internal(nameFont+16+".png"), false);
        }else
        {
            if(Gdx.graphics.getWidth() < (3*920)/2)
            {

                textGametFont = new BitmapFont(Gdx.files.internal(nameFont+32+".fnt"),
                        Gdx.files.internal(nameFont+32+".png"), false);
            }else
            {
                textGametFont = new BitmapFont(Gdx.files.internal(nameFont+64+".fnt"),
                        Gdx.files.internal(nameFont+64+".png"), false);
            }
        }

then I use this line of code to higher result quality of down and up Scaling

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

scale the image

to handle the size of the font for all type of resolution of device I use those two functions

public static float xTrans(float x)
{
    return x*Gdx.graphics.width/(YourModel.SCREEN_WIDTH);
}

public static float yTrans(float y)
{
    return y*Gdx.graphics.height/YourModel.SCREEN_Height;
}

the model screen resolution that i use is

SCREEN_WIDTH = 480

SCREEN_HEIGHT = 320

Set the scale to the font

textGametFont.setScale((xtrans(yourScale)+ ytrans(yourScale))/2f);

and finally draw your text

textGametFont.draw(batch, "WINNER !!", xTrans(250), yTrans(236));

Hope this was clear and helpful !!!
