574 Creating Interaction with ActionScript
3. Select Export for ActionScript and Export in First Frame; then give the sound the identifier
a_thousand_ways.
4. Add a button to the Stage and name it play_btn.
5. Add a button to the Stage and name it stop_btn.
6. Select Frame 1 in the main Timeline, and select Window > Actions.
Add the following code to the Actions panel:
var song_sound:Sound = new Sound();
song_sound.attachSound("a_thousand_ways");
play_btn.onRelease = function() {
song_sound.start();
};
stop_btn.onRelease = function() {
song_sound.stop();
};
This code first stops the speaker movie clip. It then creates a new Sound object
(
song_sound) and attaches the sound whose linkage identifier is a_thousand_ways. The
onRelease event handlers associated with the playButton and stopButton objects start
and stop the sound by using the
Sound.start() and Sound.stop() methods, and also
play and stop the attached sound.
7. Select Control > Test Movie to hear the sound.
To create a sliding volume control:
1. Using the Rectangle Tool, draw a small rectangle on the Stage, approximately 30 pixels
high by 10 pixels wide.
2. Select the Selection Tool and double-click the shape on the Stage.
3. Press F8 to open the Convert to Symbol dialog box.
4. Select the Button type, enter a symbol name of volume, and click OK.
5. With the button symbol selected on the Stage, enter the instance name of handle_btn in
the Property inspector.
6. Select the button, and select Modify > Convert to Symbol.
Be careful to select the movie clip behavior. This creates a movie clip with the button on
Frame 1.
7. Select the movie clip, and enter volume_mc as the instance name in the Property inspector.
