AS3获取SWF文件中AS链接

游戏中经常使用到SWF美术,但SWF文件中,会有多个元件,每个元件对应一个指定AS链接,一个元件还会有多个图层。在实际操作中,会出现要求显示一个指定元件,并在该动画资源中,有的动画要求加鼠标事件,有的则不加任何事件,即指定图层的调用。既要求过场动画的欢洽,又要求交互事件的鼠标点击时的动画效果以及配音,这里提供一个简单范例,实现代码如下:

SWF文件加载类,LoaderSwf:

  1 package  
  2 {  
  3     import flash.display.Bitmap;
  4     import flash.display.BitmapData;
  5     import flash.display.Loader;
  6     import flash.display.LoaderInfo;
  7     import flash.display.MovieClip;
  8     import flash.display.SimpleButton;
  9     import flash.display.Sprite;
 10     import flash.events.Event;
 11     import flash.events.MouseEvent;
 12     import flash.net.URLRequest;
 13     import flash.system.ApplicationDomain;
 14     import flash.system.LoaderContext;

 19     public class LoaderSwf extends Sprite

 46             /*    添加事件响应,在swf加载完毕后再获取里面的资源        */  
 47             _MovLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,onComplete);

108         }
109

配音控制类,VoicePlay:

 1 package
 2 {
 3     import flash.display.Sprite;
 4     import flash.media.Sound;
 5     import flash.net.URLRequest;

23             snd.play();
24         }
25         
26     }
27 }

过场动画配音播放帧类,XmlProject:

 1 package

32                 FrameDict[int(myxml.frame[i].@n)]=myxml.frame[i].@event;
33             }
34 
35         }

过场动画配音xml表,PlayList:

1 <play>
2     <frame n="43" event="0"></frame>    
3     <frame n="86" event="1"></frame>
4 </play>
