AS3 动态地将 MovieClip 从库附加到舞台

Question

我确实搜索过很多次，我开始认为可能是我的术语阻止了我找到答案。

我的库中有一个 MovieClip 设置为导出到 ActionScript 3.0，并带有一个名为“Info_Win”的类（它基本上是一个弹出窗口，其内容取决于它的实例名称）。

我将向主舞台添加给定数量的这些影片剪辑，并且必须为每个影片剪辑指定一个自定义实例名称，以便在它在舞台上时允许我访问它（一个数组列出了实例名称）。如前所述，Movieclip Instance 名称将定义弹出窗口的内容。

这是数组：

static public var informationWindows:Array = new Array(     
    {_informationName:"iwPanelDescription", _popupType:"3"},
    {_informationName:"iwHelpConsole", _popupType:"2"},
    {_informationName:"iwExampleInstanceName", _popupType:"1"}
);

遍历数组并返回 _informationName 应该很简单。

我遇到的问题实际上是控制 MovieClip Instance 名称的名称。在 AS2 中，我会在参数的左侧包裹一个 eval() 参数。

我正在使用以下代码：创建添加剪辑，但这并不好：

var info_win:Info_win = new Info_win();
addChild(info_win);
info_win.name = "iwPanelDescription";

从这里开始，如果我可以对实例名称问题进行排序，那么我可以使用一个简单的 for 循环来访问我创建的数组并动态设置实例名称。

尝试过这样的事情，但没有任何乐趣：

var mcName:String = "iwPanelDescription";
var this[mcName]:Info_win = new Info_win();
addChild(this[mcName]);

我们将不胜感激地接受任何可以提供帮助的事情！

Answer 1

您是否考虑过存储自己的参考与依赖舞台？

你可以像这样轻松地做到这一点：

var panels:Object = { };

panels.iwPanelDescription = new Info_win();
addChild(panels.iwPanelDescription);

trace(panels.info_win); // Get a reference via panels.

并扩展如何将其与您的 informationWindows 数组一起使用：

for each (var i:Object in informationWindows) {
    trace( panels[i._informationName] );
}

如果您想动态创建这些实例，您可以像这样使用getDefinitionByName()：

var panelClass:Class = getDefinitionByName('Info_win') as Class;
var info_win:Info_win = new panelClass();

addChild(info_win);

Answer 2

有什么问题

var mcName = "iwPanelDescription"
info_win.name = mcName;

从这里开始，如果您需要 iwPanelDescription 影片剪辑，您可以继续

var mc = this.getChildByName(mcName);

你已经完成了。
