Animation Example — Libgdx Code

Plays a frame-based animation.

import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.Animation;

	private Animation<TextureRegion> anim;
	private float state;

	@Override
	public void create() {

		Texture sheet = new Texture("walk.png");
		TextureRegion[][] frames = TextureRegion.split(sheet, 32, 32);
		anim = new Animation<>(0.1f, frames[0]);
		state = 0;
	}

	@Override
	public void render() {
		state += Gdx.graphics.getDeltaTime();
		TextureRegion frame = anim.getKeyFrame(state, true);

		Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

Libgdx Language Guide

LibGDX is a powerful, open-source Java game framework for building high-performance 2D and 3D games that run on desktop, Android, iOS, and web through a single shared codebase.

Primary Use Cases

▸Cross-platform 2D and 3D games
▸Android-first game development
▸Custom in-house engines
▸Scientific/physics simulations
▸Desktop games with OpenGL rendering

Notable Features

▸Single Java/Kotlin codebase -> multiple platforms
▸Scene2D UI and Scene2D stage/actors
▸Built-in physics via Box2D
▸OpenGL-based rendering pipeline
▸Powerful math + linear algebra library

Origin & Creator

LibGDX was created by Mario Zechner and maintained by a global open-source community focused on flexible, high-performance Java game development.

Industrial Note

LibGDX thrives in Android game development, indie 2D/3D engines, simulation-heavy games, and education-especially for teams needing full control without being locked into heavy engines.
