JavaFx Transition

Question

Мой код показан ниже. Я хочу, чтобы "ball" был прикреплен к "circle1" и go вдоль объекта "circle1", "pathtransition2" - мой код для этой цели, но он не работает.

import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.*;
import javafx.scene.paint.Color;
import javafx.event.ActionEvent;
import javafx.scene.shape.Circle;
import javafx.animation.PathTransition;
import javafx.animation.Timeline;
import javafx.util.Duration;

public class windows7 extends Application {

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

    public void start(Stage mystage) {
        Circle circle1 = new Circle(370, 370, 50);
        Circle ball = new Circle(370, 370, 11);
        Circle path = new Circle(370, 370, 300);
        circle1.setStroke(Color.GRAY);
        circle1.setFill(null);
        ball.setFill(Color.BLACK);
        Pane pane = new Pane(circle1, ball);
        Scene scene = new Scene(pane, 740, 740);
        mystage.setScene(scene);
        mystage.show();
        PathTransition pathtransition = new PathTransition(new Duration(4000), path, circle1);
        pathtransition.setCycleCount(Timeline.INDEFINITE);      
        pathtransition.play();      
        PathTransition pathtransition2 = new PathTransition(new Duration(3000), circle1, ball);
        pathtransition2.setCycleCount(Timeline.INDEFINITE);     
        pathtransition2.play();
    }

}
