Carrossel 3D

[Public2012 0]

Gostaria saber como fazer para que a imagem quando chegar em primeiro plano ela fique opaca automaticamente não apenas com a intervenção do mouse.. pode ser feito o download desse arquivo http://www.tutoriaisflash.net/2011/01/horizontal-carrossel-3d-em-flash-cs3_6986.html

tenta algo do tipo.....

 

addEventListener(Event.ENTER_FRAME, novaf); //adiciona um evento
function novaf(e:Event):void
{
if (loadedimgs = stage.stageWidth / 2;)//isso não sei se funciona mas é so para dar uma ideia 
	{
		imageHolder.alpha = 1;
	}
	else
	{
		imageHolder.alpha = 0.1;
	}
}

Obrigado IAMDIX, mas teria quer ser alguma coisa como isso

 

function addBlur():void {

var blurX:Number = 10 - Math.sin(position) * 10;

var blurY:Number = blurX;

 

var filter:BlurFilter;

 

filter = new BlurFilter(blurX, blurY, BitmapFilterQuality.LOW);

 

var filters:Array=new Array();

filters.push(filter);

this.filters = filters;

};

 

function removeBlur():void {

this.filters = null;

};

só que efeito alpha e não um filtro e achar a "position", não estou conseguindo adaptar.
