copia y pega....

Flash MX 2004

Código:

MovieClip.prototype.search = function(letter, ran) {
	var pointer:Number = 32;
	this.onEnterFrame = function() {
		tLetter = (ran) ? random(91)+31 : pointer;
		if (letter != String.fromCharCode(tLetter)) {
			this.label_txt.text = String.fromCharCode(tLetter);
		} else {
			this.label_txt.text = String.fromCharCode(tLetter);
			this.label_txt.setTextFormat(red);
			delete this.onEnterFrame;
		}
		pointer++;
	};
};
var texto:String = "Tmeister 2005 =)";
var basex:Number = 100;
var basey:Number = 100;
var red:TextFormat = new TextFormat();
red.color = 0x990000;
for (var a = 0; a<texto.length; a++) {
	var clip_mc:MovieClip = createEmptyMovieClip("x"+a, a);
	clip_mc.createTextField("label_txt", 1, 0, 0, 0, 0);
	clip_mc.label_txt.text = texto.substr(a, 1);
	clip_mc.label_txt.autoSize = true;
	clip_mc._x = basex;
	clip_mc._y = basey;
	basex += clip_mc._width-2;
	//clip_mc.search(texto.substr(a, 1), false);
	clip_mc.search(texto.substr(a, 1), true);
}

Pueden usarlo asi

clip_mc.search(texto.substr(a, 1), false);

ó

clip_mc.search(texto.substr(a, 1), true);

ustedes veran cual es la diferencia...

Saludos!!
