Actionscript Loading/Calling Sounds From String Array

Question

i'm attempting to instantiate a bunch of sounds by creating a string array containing each sound's filepath (or name).

var soundByName:Object = {};
var channelByName:Object = {};
var soundName:String;
var channelName:String;
loadSounds();

function loadSounds():void
    {
    var files:Array = new Array("sound1.mp3", "sound2.mp3"); //etc.
    for (var i:int = 0; i < files.length; i++)
        {
        soundName = files[i];
        soundByName.soundName = new Sound();
        soundByName.soundName.addEventListener(Event.COMPLETE, sound_completeHandler);
        soundByName.soundName.addEventListener(IOErrorEvent.IO_ERROR, sound_ioErrorHandler);
        soundByName.soundName.load(new URLRequest(soundName));
        }
    }

function sound_completeHandler(e:Event):void
    {
    channelName = e.currentTarget.name;
    channelByName.channelName = new SoundChannel();
    }

function sound_ioErrorHandler(e:IOErrorEvent):void
    {
    trace("Failed To Load Sound:" + e.currentTarget.name);
    }

then called like this:

//Stop a sound
channelByName["sound1.mp3"].stop();

//Play a sound
channelByName["sound2.mp3"] = soundByName["sound2.mp3"].play();

my current code contains an error from the sound_completeHandler() function stating that the 'name' property wasn't found. i can't figure out how to add this name property, or how else to reference the e.currentTarget.

Your code is wrong in 3 parts:

• soundByName is an Object and you are doing a soundByName.soundName=new Sound() => you are creating a field named soundName within soundByName. Use soundByName[soundName]=new Sound(); which mean create a field with the name taken from the variable coundName.

• You are doing the same with channelByName use channelByName[channelName]=value;

• Then you want to associate a soundChannel from your name, it can't work Sound object have no such field. Use a dictionary where you will associating the sound with the name.

  var nameBySound:Dictionary = new Dictionary();
  var soundByName:Object = {};
  var channelByName:Object = {};
  loadSounds();
  
  
  function loadSounds():void {
    var files:Array = ["sound1.mp3", "sound2.mp3"]; //etc.
    for (var i:int = 0; i < files.length; i++) {
     var soundName:String = files[i];
     var sound:Sound=new Sound(); 
     nameBySound[sound] = soundName;
     soundByName[soundName] = sound;
     sound.addEventListener(Event.COMPLETE, sound_completeHandler);
     sound.addEventListener(IOErrorEvent.IO_ERROR, sound_ioErrorHandler); 
     sound.load(new URLRequest(soundName));
    }
  }                                                                        
  
  
  function sound_completeHandler(e:Event):void {                           
   var soundName:String=nameBySound[e.currentTarget];                      
   channelByName[soundName] = new SoundChannel();                          
  }                                                                        
  
  
  function sound_ioErrorHandler(e:IOErrorEvent):void {
   trace("Failed To Load Sound:" + nameBySound[e.currentTarget]);
  }
