SwfLibrary – The easy way to load assets from swfs

Version – 0.91, updated 2010/11/20
Compatibility - AS3 (Flash Player 9 and later)

You can load fonts and movieclips from a swf at runtime using applicationDomain. It works and does the job pretty good if you just want to load a few object. You can do it like the code below, but I suggest you give this little lib a try.

var l:LoaderInfo = loader.content.loaderInfo;
var cls:Class=l.applicationDomain.getDefinition("fontClassNameHere") as Class
Font.registerFont(cls);
var l:LoaderInfo = loader.content.loaderInfo;
var cls:Class=l.applicationDomain.getDefinition("movieClipClassName") as Class
var clsObj:Object = new cls();
addChild(DisplayObject(clsObj));

Features

Fonts - Load and register fonts at runtime.
MovieClips ans sprites - Load graphics from a swf-file at runtime.
Sound - Load sound from a swf-file at runtime.
Video - Coming in the next version.
Preloader - Let the library send you updates on how many bytes have loaded.
Safemode - The loader will alert you if you name two librarys the same. Defaults to false.

Usage

  1. In the Flash IDE, select “Export for ActionScript” in the Linkage settings of the symbol you want to use.
  2. Publish the file to a SWF.
  3. Import it into your project with SwfLibrary.
  4. Access the asset like in the sample code below.
