请教JavaFx的PathTransition类的问题。

这段程序，方块“rectangle对象”沿着圆圈运动，但是每圈都要暂停一小会儿，如何让方块不要暂停？我翻遍PathTransition的API说明也没找到。



import javafx.application.Application;

import javafx.stage.Stage;

import javafx.scene.Scene;

import javafx.scene.layout.Pane;

import javafx.scene.control.Button;

import javafx.scene.layout.*;

import javafx.scene.paint.Color;

import javafx.event.EventHandler;

import javafx.scene.input.MouseEvent;

import javafx.scene.input.KeyCode;

import javafx.scene.input.KeyEvent;

import javafx.scene.shape.Circle;

import javafx.scene.shape.Line;

import javafx.scene.shape.Rectangle;

import javafx.scene.text.Text;

import javafx.scene.text.Font;

import javafx.animation.PathTransition;

import javafx.util.Duration;



public class Chapter15_11 extends Application{



	public static void main(String[] args) {

		Application.launch(args);

	}



	@Override

	public void start(Stage window) {

		Circle pathcircle = new Circle(300, 300, 250);

		Line pathline = new Line(50, 300, 550, 300);

		Circle circle = new Circle(300, 300, 12);

		Rectangle rectangle = new Rectangle(275, 275, 50, 50);

		pathcircle.setStroke(Color.DARKGRAY);

		pathcircle.setFill(null);

		rectangle.setStroke(Color.BLACK);

		rectangle.setFill(Color.LIGHTGRAY);

		Pane pane = new Pane(pathcircle, pathline, rectangle, circle);

		Scene scene  = new Scene(pane, 600, 600);

		window.setScene(scene);

		window.setTitle("PathTransition");

		window.setResizable(false);

		window.show();

		PathTransition path = new PathTransition(new Duration(3000), pathcircle, rectangle);

		path.setOrientation(PathTransition.OrientationType.ORTHOGONAL_TO_TANGENT);

		path.setCycleCount(200);

		path.setAutoReverse(false);

		path.play();	

		PathTransition path2 = new PathTransition(new Duration(3000), pathline, circle);

		path2.setCycleCount(200);

		path2.setAutoReverse(true);

		path2.play();			

	}
