and the total number of bytes for a sound file that loads into the SWF file. A text field also
displays a message when the file finishes loading. Add the following ActionScript to your FLA or
AS file:
this.createTextField("message_txt", this.getNextHighestDepth(), 10,10,300,22)
this.createTextField("status_txt", this.getNextHighestDepth(), 10, 50, 300,
40);
status_txt.autoSize = true;
status_txt.multiline = true;
status_txt.border = false;
var my_sound:Sound = new Sound();
my_sound.onLoad = function(success:Boolean) {
if (success) {
this.start();
message_txt.text = "Finished loading";
}
};
my_sound.onSoundComplete = function() {
message_txt.text = "Clearing interval";
