估计你想要的是动画效果，应该这样：
new Thread(){
public void run(){
// 动画代码：移动、渐变、缩放等
}
}.start();// 另启线程，防止阻塞当初进程
在你的代码上修改了一下,运行试试吧

图片的位移(下落),可以通过修改图片的x,y坐标来实现, 在Swing/Html中,我们可以使用Timer定时(比如每隔100毫秒)去修改图片的x,y坐标即可实现,
多个图片都按照一定的轨迹移动,那都按照自己的轨迹的算法,去定时修改x,y坐标即可.
JavaFX是java先进的图形界面框架, 里面有3D和各种动画, 所以按照轨迹移动,都能轻松实现
JavaFX参考代码如下

hbox.setLayoutY(230);
Group root = new Group();
root.getChildren().addAll(imv, path, hbox); // 不添加path.就可以不显示path了
Scene scene = new Scene(root, 430, 300);
primaryStage.setTitle("JavaFX");
primaryStage.setScene(scene);
primaryStage.show();
//旋转动画设置
