java - 让 JavaFX 应用程序在动画之间等待

Question

我正在使用 JavaFX 开发一个简单的游戏。我想要的是在循环结束时，应用程序等待指定的时间，然后再次运行。

当我在应用程序线程上运行此代码时， View 不会更新，节点也会消失，而我看不到动画。

如果我创建一个新线程，那么什么也不会发生。由于该动画在游戏完成之前不会运行，因此在动画完成之前是否其他任何操作都没有关系。

下面是我的代码，感谢任何帮助。

private void playWonAnimation(){
    Random rand = new Random();
    for (Node block: tower02List) {
        double xTrans = rand.nextInt(800) + 700;
        double yTrans = rand.nextInt(800) + 700;

        TranslateTransition translate = new TranslateTransition(Duration.millis(2500), block);
        xTrans = (xTrans > 1100) ? xTrans : -xTrans;
        translate.setByX(xTrans);
        translate.setByY(-yTrans);

        RotateTransition rotate = new RotateTransition(Duration.millis(1200), block);
        rotate.setByAngle(360);
        rotate.setCycleCount(Transition.INDEFINITE);

        ParallelTransition seq = new ParallelTransition(translate, rotate);
        seq.setCycleCount(1);
        seq.play();
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

将所有动画放入 SequentialTransition 中，用 PauseTransition 分隔:

private void playWonAnimation(){
    Random rand = new Random();
    SequentialTransition seq = new SequentialTransition();
    for (Node block: tower02List) {
        double xTrans = rand.nextInt(800) + 700;
        double yTrans = rand.nextInt(800) + 700;

        int translateTime = 2500 ;
        int oneRotationTime = 1200 ;

        TranslateTransition translate = new TranslateTransition(Duration.millis(translateTime), block);
        xTrans = (xTrans > 1100) ? xTrans : -xTrans;
        translate.setByX(xTrans);
        translate.setByY(-yTrans);

        RotateTransition rotate = new RotateTransition(Duration.millis(translateTime), block);
        rotate.setByAngle(360 * translateTime / oneRotationTime);

        seq.getChildren().add(new ParallelTransition(translate, rotate));
        seq.getChildren().add(new PauseTransition(Duration.seconds(1.0)));
    }

    seq.play();
}
