JavaFX Game Development Framework

Why FXGL?

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 {

    @Override
    protected void initSettings(GameSettings settings) {
        settings.setWidth(800);
        settings.setHeight(600);
        settings.setTitle("Basic Game App");
    }

    public static void main(String[] args) {
        launch(args);
    }
}
