嵌入 SWF 文件与嵌入图像几乎是相同的。 差别在于您可以将嵌入的 SWF 文件的实例当作 MovieClip 类的实例处理。 (它们实际上是 MovieClipAsset 类的子类,MovieClipAsset 类是 MovieClip 类的子类。)
注意: 您无法直接访问嵌入的 SWF 文件的属性或方法。 但是,您可以使用 LocalConnection 以允许它们进行通信。

嵌入 SWF 库资源
您可以在应用程序中嵌入来自现有 SWF 库中的特定符号。 Flash 定义三种类型的符号: Button、MovieClip 和 Graphic。 您可以在 Flex 应用程序中嵌入 Button 和 MovieClip 符号,但您不能嵌入 Graphic 符号,因为无法为 ActionScript 导出 Graphic 符号。
此示例使用 [Embed] 元数据标签的 source 属性来指定包含您的库的 SWF 文件,并使用 [Embed] 元数据标签的 symbol 属性来指定您要在该库中嵌入的符号的链接 ID。?

例子3：
下面的例子使用3个不同的标识符加载“assets/icons.swf”文件。每个资源都被赋予了不用的变量。这样即使使用同一个SWF文件，它们也能很容易的引用独立的资源。?

<? xml ? version = "1.0" ? encoding = "utf-8" ?> ??
-
??
-
< mx:Application ? xmlns:mx = "http://www.adobe.com/2006/mxml" ? layout = "vertical" ? verticalAlign = "middle" ? backgroundColor = "white" > ??

????< mx:Script > ??

你也可以重构一下代码，使它看起来跟优雅。把Embed标签和各种变量移到一个独立的ActionScript文件中，就像下面这样。
Images.as:
-
package ??
-
{??
-
????public ? class ?Images??
-
????{??
-
????????[Embed('assets/icons.swf' ,?symbol= 'bulletCheck' )]??
-
????????public ? static ? const ?BULLET_CHECK:Class;??
-
??
-
????????[Embed('assets/icons.swf' ,?symbol= 'bulletCritical' )]??
-
????????public ? static ? const ?BULLET_CRITICAL:Class;??
-
??
-
????????[Embed('assets/icons.swf' ,?symbol= 'bulletWarning' )]??
-
????????public ? static ? const ?BULLET_WARNING:Class;??
-
????}??
-
}??
-
<? xml ? version = "1.0" ? encoding = "utf-8" ?> ??
-
??
-
< mx:Application ? xmlns:mx = "http://www.adobe.com/2006/mxml" ? layout = "vertical" ? verticalAlign = "middle" ? backgroundColor = "white" > ??
-
??
-
????< mx:Button ? id = "checkBtn" ? label = "Check" ? icon = "{Images.BULLET_CHECK}" ? /> ??
-
????< mx:Button ? id = "warningBtn" ? label = "Warning" ? icon = "{Images.BULLET_WARNING}" ? /> ??
-
????< mx:Button ? id = "critcalBtn" ? label = "Critical" ? icon = "{Images.BULLET_CRITICAL}" ? /> ??
-
??
-
</ mx:Application >
