Sound class

Availability

Description

The Sound class lets you control sound in a movie. You can add sounds to a movie clip from the library while the movie is playing and control those sounds. If you do not specify a target when you create a new Sound object, you can use the methods to control sound for the whole movie.

You must use the constructor new Sound to create a Sound object before calling the methods of the Sound class.

Description

Constructor; creates a new Sound object for a specified movie clip. If you do not specify a target instance, the Sound object controls all of the sounds in the movie.

Example

The following example creates a new Sound object called global_sound. The second line calls setVolume() and adjusts the volume on all sounds in the movie to 50%.

global_sound = new Sound();
global_sound.setVolume(50);

The following example creates a new Sound object, passes it the target movie clip my_mc, and calls the start method, which starts any sound in my_mc.

movie_sound = new Sound(my_mc);
movie_sound.start();
