file. If you load a SWF file into a movie clip in another SWF file, any references to
loaded SWF file resolve to the root Timeline in the host SWF file, not that of the loaded SWF
file. This can sometimes lead to unexpected behavior at runtime, for example, if the host SWF file
and the loaded SWF file both use
In Flash Player 7 and later, you can use the

_root

About accessing data in loaded SWF files
One SWF file can load another SWF file from any location on the Internet. However, for one
SWF file to access data (variables, methods, and so forth) defined in the other SWF file, the two
files must originate from the same domain. In Flash Player 7 and later, cross-domain scripting is
prohibited unless the loaded SWF file specifies otherwise by calling
System.security.allowDomain()

System.security.allowDomain()

Loading external MP3 files

To load MP3 files at runtime, use the
Sound object:
var song_1_sound = new Sound();
You then use the new object to call
sounds are loaded completely before being played; streaming sounds are played as they are
downloaded. You can set the
event sound or a streaming sound. After you load an event sound, you must call the
method of the Sound class to make the sound play. Streaming sounds begin playing when
sufficient data is loaded into the SWF file; you don't need to use
For example, the following code creates a Sound object named
MP3 file named beethoven.mp3:
var classical:Sound = new Sound();
classical.loadSound("http://server.com/mp3s/beethoven.mp3", true);
In most cases, set the
files that should start playing as soon as possible—for example, when creating an MP3 "jukebox"
application. However, if you're downloading shorter sound clips and need to play them at a
specified time (for example, when a user clicks a button), set
