actionscript-3 - 出现错误 #1006 removeChild 不是函数。定时器延迟 removeChild

Question

我正在尝试构建一个条件语句，该语句将在不同的 Timer Delay 时 addChild 和 removeChild。在我走得更远之前，我想，我应该提一下，我正在使用 TweenMax 来缓和缓和 Child 的 alpha 从 1 到 0 并在模拟淡入/淡出的过程中返回。

我只遇到一行问题 - 在条件语句中。它运行“正常”。电影按我想要的方式运行，但是删除/添加子转换的速度不是我想要的速度。我在输出中收到一条错误消息，但除此之外，电影运行良好。

请注意，我还是 AS3 的新手。我的脚本重复且冗长。对不起！我已经评论了错误所在的位置。先谢谢了！！

Answer 1

您可能会因为嵌套函数的方式（存在问题的方式）而失去上下文。似乎认为“这个”既不是（1）舞台，也不是（2）DisplayObject。当您在该行上抛出断点并在调试中运行时会发生什么？

编辑：您将 eventListener 添加到 Timer 对象上—— Timer 不是 DisplayObject，因此没有 removeChild 作为函数。

Answer 2

现在您已经过去了 #1006（尝试在 Timer 对象上调用 DisplayObject 方法）并遇到了 #2025 错误（无法删除不存在的孩子），这是我对正在发生的事情的评估。

这里的主要问题是您要向共享的 removeKid 计时器添加多个侦听器（每次单击一个），并且它们都引用相同的 oldSection 实例。因此，在您单击 10 次后，您的 timerListener 函数将尝试调用 removeChild(oldSection) 10 次（其中 9 次将失败并出现错误 #2025）。

此处最简单的解决方法是利用 TweenMax 的 onComplete 参数，因为您可能希望在旧的 DisplayObject 完全淡出后删除它。这也将允许您删除共享的 removeKid 计时器。例如：

TweenMax.to(oldSection, 1, {
    alpha:0,
    ease:Quint.easeInOut,
    onComplete:fadeCompletedHandler,
    onCompleteParams: [oldSection]
    });

function fadeCompletedHandler(child:DisplayObject):void
{
    removeChild(child);
}
