Flash - loop variables

Hey guys, I'm trying to put the following in a loop.
var ButtonOne:MovieClip = BouncingBallBtn;
var ButtonTwo:MovieClip = BallControlsBtn;
var ButtonThree:MovieClip = DiceBtn;
var ButtonFour:MovieClip = SlideShowBtn;
var ButtonFive:MovieClip = SlideShowControlBtn;
var ButtonSix:MovieClip = QuizBtn;

Open in new window


is it possible to actually put it in a loop?
I'm trying it like this, but I get an error everytime.

var buttons:Array = ["ButtonOne","ButtonTwo","ButtonThree","ButtonFour","ButtonFive","ButtonSix"];
var names:Array = ["BouncingBall", "BallControls", "Dice", "SlideShow", "SlideShowControl", "Quiz"];

for(var a:Number=0;a<6;a++){
	var appName:MovieClip = this[names[a] + "Btn"];
	this[buttons[a]]:MovieClip = appName;
}

I think your approach is problematic. You can't really assign a movieclip (or button) to another movieclip. Movieclips are not variables that you can assign to.

If all you're trying to do is find an easy way to access your buttons, then your "names" array should be sufficient

// do something with BallControls
var ballMC:MovieClip = MovieClip(this[names[a] + "Btn"]);

If you're trying to do something to all your buttons (like add event listeners), then just iterate through the list

for (var a:int = 0, l:int = names.length; a < l; ++a){
  var appName:MovieClip = MovieClip(this.getChildByName(names[a] + "Btn"));
  this.addEventListener(Event.CLICK, buttonClicked);
}

If you're trying to do something more complex, please let us know.

Just drop the quotes alltogether. You can define the array elements as references to the clips directly. There's no need for getChildByName as long as the clips exist.
var names:Array = [BouncingBallBtn, BallControlsBtn, DiceBtn, SlideShowBtn, SlideShowControlBtn, QuizBtn];

for (var i:int = 0; i < names.length; ++i)
{
    var btn:SimpleButton = names[i] as SimpleButton;
    btn.addEventListener (Event.CLICK, buttonClicked);
}

As a side note, if you use flash.utils.Dictionary, you can then create a Dictionary object with those same buttons as the keys. In your click handler, you can lookup the values of your dictionary to switch and decide how to handle the event.
