我对actionscript3很新，我目前正在开发滑动益智游戏。游戏就像，你在一个矩阵中生成8个盒子，每个盒子都有一个数字，你可以滑动盒子按照一定的顺序排列它们。好吧，我已经完成了大部分所需的功能，但有一件事 - 如果按下“下一步”按钮，则不能再移动这些框。
我会在这里粘贴我的代码，包括主类和盒子类。

问题是，应该通过点击“下一步”按钮启动新游戏，但是当你这样做时，这些框不能再移动了。
答案 0 :(得分：1)
对我来说，这并非100％明确，但在您的nextMatrix()方法中，您正在删除事件侦听器。但是你永远不会从舞台上移除这些盒子（或者它们被添加到的任何容器）。
然后在buildMatrix()中添加新框并向其添加事件侦听器。
我认为发生的事情是原始框仍然存在，但没有事件监听器附加到它们。您的nextMatrix()函数应该有一个循环，它使用removeChild()方法删除原始框。
即使这不能解决您当前的问题，它也会从舞台上删除这些对象并释放他们正在消耗的内存。
我不明白的是，通常当你addChild()时，它应该将对象添加到已经存在的任何内容之上。所以其他东西可能导致问题。但正如我所提到的那样，在旧盒子上做removeChild()时，每次开始新游戏时它们都会持续存在并消耗更多内存。
<强> [编辑]
应该发生的另一件事是您需要清除boxes方法中的nextMatrix()数组。否则，buildMatrix()方法中的代码会将事件侦听器添加到原始框中，而不是新框。
重置该阵列的两种快速方法：
boxes.length = 0;
或
boxes = [];
