getBytesLoaded (Sound.getBytesLoaded method)
public getBytesLoaded() : Number
Returns the number of bytes loaded (streamed) for the specified Sound object. You can
compare the value of getBytesLoaded() with the value of getBytesTotal() to determine
what percentage of a sound has loaded.
Returns
Number - An integer indicating the number of bytes loaded.
Example
The following example dynamically creates two text fields that display the bytes that are
loaded 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";
clearInterval(my_interval);
};
my_sound.loadSound("song2.mp3", true);
var my_interval:Number;
my_interval = setInterval(checkProgress, 100, my_sound);
function checkProgress(the_sound:Sound):Void {
var pct:Number = Math.round(the_sound.getBytesLoaded()/
the_sound.getBytesTotal() 100);
var pos:Number = Math.round(the_sound.position/the_sound.duration 100);
status_txt.text = the_sound.getBytesLoaded()+" of
"+the_sound.getBytesTotal()+" bytes ("+pct+"%)"+newline;
status_txt.text += the_sound.position+" of "+the_sound.duration+"
milliseconds ("+pos+"%)"+newline;
}
