JavaFX Game Development Framework

Maven Central Build Status codecov sponsor JFXCentral


  • No installation or setup is required
  • "Out of the box": Java 8-21, Win/Mac/Linux/Android 8+/iOS 11.0+/Web
  • Simple and clean API, higher level than other engines
  • Superset of JavaFX: no need to learn new UI API
  • Real-world game development techniques: Entity-Component, interpolated animations, particles, and many more
  • Games are easily packaged into a single executable .jar, or native images

Good for:

  • Any 2D game (side-scroller / platformer / arcade / RPG)
  • Any business application with complex UI controls / animations
  • Experimental 3D
  • Hobby / academic / commercial projects
  • Teaching / learning / improving game development skills
  • Fast prototyping of app ideas

Minimal Example

public class BasicGameApp extends GameApplication {

    protected void initSettings(GameSettings settings) {
        settings.setTitle("Basic Game App");

    public static void main(String[] args) {
