You want to use ActionScript to attach a sound from the Library to your movie at runtime.
Use the Sound.attachSound( ) method.
A sound must be attached to a movie clip before it can be played at runtime. You can programmatically attach sounds from the Library to Sound objects using the attachSound( ) method. To use this method properly, you must first do three things:
Create a Sound object (see Recipe 13.1).
Import a sound into the Library using File Import to Library.
Set the sound symbol to export and set its linkage identifier using the Linkage option in the Library panel's pop-up Options menu.
After successfully completing these three steps, you can call the attachSound( ) method and pass it the linkage identifier of the sound symbol to attach:
// Include Sound.as to access the createNewSound( ) method from Recipe 13.1. #include "Sound.as" // Create a new Sound object. mySound_sound = Sound.createNewSound( ); // Attach a sound to the Sound object. The Library sound symbol // must be set to export and have a linkage identifier that matches // the string passed to attachSound( ). mySound_sound.attachSound("MySoundSymbol");
Attached sounds do not start playing until you tell them to do so. See Recipe 13.3 for more information about playing sounds. Recipe 14.5 demonstrates how to use Microphone.attachAudio( ) to attach audio data from the user's microphone.
