在javafx中克隆或复制形状？ [英] Clone or duplicate shapes in javafx?

问题描述

我在javafx中使用Scenebuilder 2.0为GUI创建了一个Connect 4游戏。这基本上是从顶部下载芯片的动画片：

I'm making a Connect 4 game in javafx using Scenebuilder 2.0 for the GUI. This is basically what the animation for the chip coming down from top:

@FXML
private void click0(javafx.event.ActionEvent event) {
    TranslateTransition translate = new TranslateTransition(
            Duration.millis(750));
    translate.setToX(1);
    translate.setToY(432);
    ParallelTransition transition = new ParallelTransition(c0,translate);
    transition.setCycleCount(1);
    transition.play();
}

当我点击直接位于所有行下方的按钮时，会发生这种情况。它还没有完成。但是我怎么能拥有一个重复的圈子（c0）保持原来的位置？

This happens when I click the buttons which is directly below all the rows. It isn't nearly complete yet. But how can I have a duplicate of the circle (c0) stay in the original position?

推荐答案

很简单 - 只是声明另一个与c0完全一样的圈子：

Very simple-- just declare another circle that is exactly the same as c0:

Circle c0copy = c0;

并将其添加到容器中的原始位置c0位于：

and add it to the original location in the container c0 is in:

yourPane.getChildren().add(c0copy);

如果你想在任何时候删除它（或任何其他任何窗格的孩子，将 remove（）更改为其他东西）：

If you want to remove it at any point (or do anything else with any of the pane's children by changing remove() to something else):

yourPane.getChildren().remove(c0copy);
