Does anyone know how I can use a TTF font in libGDX? I have looked around and have seen things about StbTrueTypeFont but it doesn't seem to be in the latest release.
EDIT: I found the StbTrueType font stuff, the jar file is located in the extensions directory. I've added it to my project. Now I just need to figure out how to use it. Any examples?
Yes you will definitely need to add the gdx-stb-truetype jars to your project as you stated in your edit. Here is how you will use it, pretty straighforward...
First you need to declare your BitmapFont and the characters you will use...
BitmapFont font;
public static final String FONT_CHARACTERS = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789][_!$%#@|\\/?-+=()*&.;,{}\"´`'<>";
Then you need to create the font...
font = TrueTypeFontFactory.createBitmapFont(Gdx.files.internal("font.ttf"), FONT_CHARACTERS, 12.5f, 7.5f, 1.0f, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
font.setColor(1f, 0f, 0f, 1f);
You can play with the arguments you pass to createBitmapFont() and you will see what they do.
Then to render the font you would do it as you normally do...
batch.begin();
font.draw(batch, "This is some text", 10, 10);
batch.end();
com.badlogic.gdx.scenes.scene2d.ui.Label? Or does it impossible? –
Condyloma BitmapFont, you can apply to a Label by passing a LabelStyle in the Label constructor. In the LabelStyle you can specify a font. libgdx.badlogicgames.com/nightlies/docs/api/com/badlogic/gdx/… –
Ketene Use the gdx-freetype extension:
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(fontFile);
BitmapFont font15 = generator.generateData(15);
BitmapFont font22 = generator.generateData(22);
generator.dispose();
"To use gdx-freetype, grab the latest nightlies, link gdx-freetype.jar and gdx-freetype-natives.jar to your desktop project, link gdx-freetype.jar to your Android project, and copy the armeabi/libgdx-freetype.so and armeabi-v7a/libgdx-freetype.so files to your Android project’s libs/ folder, just like with the libgdx.so files."
setColor(r, g, b, a)? libgdx.l33tlabs.org/docs/api/com/badlogic/gdx/graphics/g2d/… –
Ketene Did researched a lot and found this working method:
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("myfont.ttf"));
FreeTypeFontParameter parameter = new FreeTypeFontParameter();
parameter.size = 12; // font size
BitmapFont font12 = generator.generateFont(parameter);
generator.dispose(); // avoid memory leaks, important
Use this if you failed tried answers above, libGDX Freetype Wiki for reference.
This is working on an S4 clone phone: Pinewood is a downloaded font, in assets folder. See the folder structure below.

public void resume() {

public void dispose() {

you have to use FreeTypeFont library. github
1.as the github page say, for projects using gradle add this dependencies:
Core Dependency:
compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
Desktop Dependency:
compile "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-desktop"
Android Dependency:
compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-armeabi"
natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-armeabi-v7a"
natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-arm64-v8a"
natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-x86"
natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-x86_64"
for more details and platforms see this page
if you don't use gradle see this
2.after library added to your project you can use it like this:
FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("myfont.ttf"));
FreeTypeFontParameter parameter = new FreeTypeFontParameter();
parameter.size = 12;
BitmapFont font12 = generator.generateFont(parameter); // font size 12 pixels
generator.dispose(); // don't forget to dispose to avoid memory leaks!
and put myfont.ttf in core assets folder
