"TypeError: Error #1010: A term is undefined and has no properties" in AS3

Question

我正在使用 Adobe Animate CC 创建一个 Android 游戏作为我们的论文，每次我测试我的作品时，一开始它运行良好，但是当我进入主游戏时，有一个出现错误：

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]

这是我的代码（包括注释代码）：

糟糕！我的代码太长了。我检查了很多次我的代码没有错，我也调试了它仍然出现这种错误。我已经声明了 corekWin（动画片段），但是 corekWin 中的 btnGo（另一个可以点击的动画片段）不需要声明它，对吧？因为已经声明了 corekWin。

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。您认为这段代码有什么问题？

Answer 1

关于这一行：

var corekWin:MovieClip = new MovieClip;

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

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

它失败了，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 是您的库 (ctrl+L) 中的一个 MovieClip，那么您应该给它一个 linkage名称（右击并转到属性并提供链接名称，例如将其命名为 mc_corekWin）。

现在在您的代码中，您可以实例化现有的 MovieClip 而不是创建一个新的空 MovieClip...:[=31=]

var corekWin : mc_corekWin = new mc_corekWin();

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

编辑 :

如果您的 MC 已经放在舞台上（在运行时），那么您不需要创建 new Movieclip（甚至 new mc_corekWin）变量。只需通过您给它的实例名称引用 MC。

要撤消链接只需返回库中的 MC 属性并取消勾选 "Export for Actionscript"框.
要添加一个实例名称，单击 MC（在舞台上单击它，而不是库）并打开 Properties 选项卡 (ctrl+F3)，您会看到一个为您的首选名称准备好的部分。您键入的名称（并按 Enter 更新）将在代码中使用。

基本上，如果 MC xyz 已经在舞台上，您不需要 var xyz:MovieClip = new MovieClip;（这将覆盖舞台上的 MC）通过代码控制它，只需给它一个实例名称然后使用名称在代码中引用MC。

可能您不需要 gril 和 linya 等变量成为 new MovieClip。尝试取消对它们的注释（使用 //）并查看它们现在是否变为 "not visible"。
