animation - 让 rotateTransition 和 pathtransition 在可调整大小的窗口上工作

Question

我在开发一个测试 Javafx 程序时遇到了一点问题，该程序处理从不同方向在屏幕上传递矩形对象。为了完成这项工作，我创建了矩形对象，然后创建了三个线对象。然后，我创建了一个 PathTransition 对象，该对象将沿着每个线对象移动一个矩形。从那里，我创建了一个 Pane 对象，并在其顶部添加了三个矩形和三条线。为了模拟矩形来自不同方向，我使用了 RotateTransition 对象并将 Pane 对象用作其节点。基本上，该程序只是一个旋转窗格，其中包含三行，每行都有一个矩形沿着所述行的路径向下移动。但是，当我想调整窗口大小时，我不会 不知道如何在不弄乱动画的情况下准确地使窗格的大小随之变化。任何帮助将不胜感激。谢谢！这是代码：

        BorderPane borderPane = new BorderPane();
        borderPane.setCenter(pane);
        Scene scene = new Scene(borderPane, 1000, 1000);

        // Bind the BorderPane to the scene
        borderPane.prefHeightProperty().bind(scene.heightProperty());
        borderPane.prefWidthProperty().bind(scene.widthProperty());
        primaryStage.setTitle("Test");
