Flex从swf中加载资源和类
package{import flash.display.Sprite;public class TestAssets extends Sprite{public function TestAssets(){}[Embed(source="/assets/images/volume_back.png")]public static var test1:Class;}}
?
在Flash中新建项目：test.fla，导入一个图片到库中，拖到舞台，然后F8，创建影片剪辑，将该影片剪辑的AS链接起名为testClass。
因为还想要打包进去一个XML，于是创建一个空元件，将其AS链接起名为ClassA，并创建ClassA.as：
package {import flash.display.MovieClip;public class ClassA extends MovieClip {public function ClassA() {// constructor code}public static var theXML:XML = <root><item title="title123"><name>Jason</name></item></root>;public var theVar:String = "variable" + new Date().time;}}?
?
Flex代码：
