AS3中的“ TypeError：错误＃1010：术语未定义且没有属性”

Question

我正在使用Adobe Animate CC创建一个Android游戏，并且每次我测试我的作品时，最初都可以正常工作，但是当我进入主游戏时，会出现错误：

Error #1010: A term is undefined and has no properties at RECOVER_RECOVER_dmthesis_demo_ver__paggumanarename_Scene14_fla::MainTimeline/frame1()[RECOVER_RECOVER_dmthesis_demo_ver__paggumanarename_Scene14_fla.MainTimeline::frame1:160]

糟糕！ 我的代码太长。 我检查了我的代码很多次，没有错，我也对其进行了调试，这种错误仍然出现。 我已经声明了corekWin（影片剪辑），但是corekWin内部的btnGo（另一个可以单击的影片剪辑）不需要声明，对吗？ 因为corekWin已经声明。

我正在尝试修复该错误，不幸的是，它失败了。 我已经仔细检查过了。 您认为此代码有什么问题？

Answer 1

关于这条线：

var corekWin:MovieClip = new MovieClip;

您刚刚创建了一个新的空白（ 空 ）MovieClip对象，其引用名称为corekWin ，因为您从未做过corekWin.addChild(btnGo); 你不能说;

corekWin.btnGo.addEventListener(MouseEvent.CLICK, gorabelx);

它失败是因为corekWin是一个空的new Movieclip ，它不包含任何btnGo对象。

可能的解决方案 ：

如果corekWin是corekWin 库 （ctrl + L）中的MovieClip，则应为其指定一个链接名称（右键单击并转到Properties并指定一个链接名称，例如，将其命名为mc_corekWin ）。

现在，在您的代码中，您可以实例化该现有的MovieClip而不是创建一个新的空对象...：

var corekWin : mc_corekWin = new mc_corekWin();

在调整任何视觉方面之前，请通过stage.addChild(corekWin);将其添加到舞台中stage.addChild(corekWin); 然后，您可以执行corekWin.visible或corekWin.alpha等。

编辑 ：

如果您的MC已放置在舞台上（在运行时），则无需创建new Movieclip （甚至是new mc_corekWin ）变量。 只需通过您为其指定的实例名称来引用MC。

• 要撤消链接，只需返回“ 库 ”中MC的属性，然后取消选中“导出为Actionscript”框。

• 要添加实例名称，请单击MC（在舞台上单击它，而不是在Library上单击），然后打开“ Properties” （ 属性）选项卡（ctrl + F3），您会看到准备使用您的首选名称的部分。 您键入的名称（然后按Enter进行更新）将在代码中使用。

基本上，如果MC xyz已经在舞台上，则不需要var xyz:MovieClip = new MovieClip; （这将覆盖舞台上的MC）以通过代码进行控制，只需为其指定实例名称，然后使用该名称在代码中引用MC即可。

可能您不需要像gril和linya这样的var都是new MovieClip 。 尝试取消注释它们（使用// ），然后查看它们是否现在变得“不可见”。
