Question

scene.addEventHandler(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>() {

    @Override     
    public void handle(MouseEvent me){
        Circle circle = new Circle(10, 20,50);
        circle.setFill(Color.GREEN);
        root.getChildren().add(circle);
        animation = ParallelTransitionBuilder.create()
        .node(circle)
        .children(
            TranslateTransitionBuilder.create()
                .duration(Duration.seconds(2))
                .fromX(me.getSceneX())
                .toX(me.getSceneX()+10)
                .build()

        )
        .cycleCount(Timeline.INDEFINITE)
        //.autoReverse(true)
        .build();      
    }

    public void play() {
    animation.play();
}

//public void stop() {
//animation.stop()

我想在场景中circle move时mouse click。它没有发生！

我不确定序列是否错误，即在动画开始之前将对象添加到根？

我对您的代码进行了一些编辑，它似乎对我有用

scene.addEventHandler(MouseEvent.MOUSE_CLICKED, new EventHandler<MouseEvent>() {

        @Override     
        public void handle(MouseEvent me){
            Circle circle = new Circle(10, 20,50);
            circle.setFill(Color.GREEN);
            root.getChildren().add(circle);
            Animation animation = ParallelTransitionBuilder.create()
            .node(circle)
            .children(
                TranslateTransitionBuilder.create()
                    .duration(Duration.seconds(2))
                    .fromX(me.getSceneX())
                    .toX(me.getSceneX()+10)
                    .build()

            )
            .cycleCount(Timeline.INDEFINITE)
            .autoReverse(true)
            .build();
            animation.play();
       }
});

尽管如此，我仍然没有得到的是

的目的

public void play() {
    animation.play();
}

你在哪里叫它！
