attachAudio (MovieClip.attachAudio method)
public attachAudio(id:Object) : Void
Specifies the audio source to be played. To stop playing the audio source, pass the value
false
for the
id
.
You can extend the methods and event handlers of the MovieClip class by creating a subclass.
Availability: ActionScript 1.0; Flash Player 6 - The ability to attach audio from Flash Video
(FLV) files was added in Flash Player 7.
Parameters
id :Object
- The object that contains the audio to play. Valid values are a Microphone object,
a NetStream object that is playing an FLV file, and
false
(stops playing the audio).
Example
The following example creates a new NetStream connection. Add a new Video symbol by
opening the Library panel and selecting New Video from the Library options menu. Give the
symbol the instance name
my_video
. Dynamically load the FLV video at runtime. Use the
attachAudio()
method to attach the audio from the FLV file to a movie clip on the Stage.
Then you can control the audio in the movie clip by using the Sound class and two buttons
called
volUp_btn
and
volDown_btn
.
var my_nc:NetConnection = new NetConnection();
my_nc.connect(null);
var my_ns:NetStream = new NetStream(my_nc);
my_video.attachVideo(my_ns);
my_ns.play("yourVideo.flv");
this.createEmptyMovieClip("flv_mc", this.getNextHighestDepth());
flv_mc.attachAudio(my_ns);
var audio_sound:Sound = new Sound(flv_mc);
// Add volume buttons.
volUp_btn.onRelease = function() {
if (audio_sound.getVolume()<100) {
audio_sound.setVolume(audio_sound.getVolume()+10);
updateVolume();
}
};
volDown_btn.onRelease = function() {
if (audio_sound.getVolume()>0) {
