嗨，伙计们，我正试图添加一个卡翻转动画到我的游戏，但我得到一些例外，我不明白，我没有得到他们所有的时间，就像有时，有时他们停止过渡。输入图像描述这里是我的过渡代码。

public void transitionAnimation(ImageView imageView,Image image){
    ScaleTransition front = new ScaleTransition(Duration.seconds(0.15),imageView);
    ScaleTransition back = new ScaleTransition(Duration.seconds(0.15),imageView);

    front.setFromX(1);
    front.setToX(0);
    front.setCycleCount(1);
    front.play();

    back.setFromX(0);
    back.setToX(1);
    back.setCycleCount(1);
    back.setDelay(Duration.seconds(0.15));
    back.play();

    Timer timer = new Timer();
    TimerTask timerTask = new TimerTask() {
        @Override
        public void run() {
            imageView.setImage(image);
            timer.cancel();
            timer.purge();
        }
    };
    timer.schedule(timerTask,148);
}

你的 TimerTask 在后台线程上运行，并更新 ImageView 从那根线。因为javafx和大多数ui工具包一样，是单线程的，所以这里的行为是不确定的；您看到了跨多个线程的数据不一致的影响。
只需使用动画api专门管理这样的功能；e、 g.使用 SequentialTransition :

public void transitionAnimation(ImageView imageView,Image image){
    ScaleTransition front = new ScaleTransition(Duration.seconds(0.15),imageView);
    ScaleTransition back = new ScaleTransition(Duration.seconds(0.15),imageView);

    front.setFromX(1);
    front.setToX(0);
    front.setCycleCount(1);

    front.setOnFinished(e -> imageView.setImage(image));

    back.setFromX(0);
    back.setToX(1);
    back.setCycleCount(1);

    new SequentialTransition(front, back).play();

}

或者 Timeline :

public void transitionAnimation(ImageView imageView,Image image){

    KeyFrame start = new KeyFrame(Duration.ZERO, new KeyValue(imageView.scaleXProperty(), 1.0));
    KeyFrame middle = new KeyFrame(
        Duration.millis(150),
        e -> imageView.setImage(image),
        new KeyValue(imageView.scaleXProperty(), 0.0)
    );
    KeyFrame end = new KeyFrame(Duration.millis(300), new KeyValue(imageView.scaleXProperty(), 1.0));
    new Timeline(start, middle, end).play();
}
