Hi there, thanks for checking my post. I am trying to create a class that will
play a number of mp3 loops each a specified number of times and in the
specified order. I have tried to find an existing class but cant find one
anywhere.
My solution (which may not be that efficient), is to create all of the sound
objects in the fla then load the mp3s into them. When they are all loaded each
sound object is added to a new object that holds it as well as a 'loops'
property that says how many times the sound object must play. These objects are
then put into an array in the order they are to be heard. This array is passed
to my LoopSound class that controls the playback. I can also pass a
'loopForever' property that will make the series repeat indefinitely.
The problem I am having is re-triggering the play() function from within my
LoopSound Class to move onto the next sound in the array. I am sure that there
will be a much neater way of achieving what I want, and maybe even a
pre-written class!
Any direction / suggestions / encouragement much appreciated :)
Thanks!
Danny
//this code would create an instance of the class in the FLA
var mySound:Sound = new Sound();
mySound.loadSound("sounds/gas.mp3", false);
//once sound is loaded:
var my_ar:Array = new Array();
//create object to add to array
var myOb:Object = new Object();
myOb.sound = mySound;
//is to play 3 time
myOb.loops = 3;
my_ar.push(myOb);
var myLooper:LoopSound = new LoopSound(my_ar)
Here is the class:
//this class is designed to play a number of already loaded sound objects
sequentially, each sound object can be looped for a specified number of times
then the whole series can be repeated infinitely. Th constructor is passed an
array of objects that have sound and loop properties that contain a sound
object and the number of times the sound object is to be looped.
class LoopSound {
private var sounds_ar:Array;
//sound playing currently
var currSound:Sound;
//which stage of the array we are currently up to
private var mp3Count:Number = 0;
//if this series of loops is meant to keep playing until they are
stopped
private var loopForever:Boolean;
//receives array that holds objects that have the key sound & loops
public function LoopSound(a:Array, lF:Boolean) {
trace("loopsound created:"+a);
mp3Count = 0;
sounds_ar = new Array();
sounds_ar = a;
loopForever = lF;
this.play();
}
private function play() {
trace("Loopsound started playing");
trace("mp3 count:"+this.mp3Count+":"+sounds_ar);
currSound = sounds_ar[mp3Count]["sound"];
//creating local vars for targetting from currSound complete
var mp3C:Number = mp3Count;
var snds_ar:Array = sounds_ar;
//calculate number of times mp3 is to loop
var currLoops:Number = sounds_ar[mp3Count]["loops"];
currSound.start(0,currLoops);
currSound.onSoundComplete = function() {
//if there are more sound objects to play iterate thru
array and retrigger play()
if (mp3Count<snds_ar.length) {
mp3Count++;
//this bit isn't working!
play();
} else {
if (loopForever) {
mp3Count = 0;
this.play();
} else {
//all sound objects have played and
play() is not retriggered
mp3Count = 0;
}
}
};
}
}
