//**
arrayAphid*.buttonMode = true;
arrayAphid*.addEventListener(MouseEvent.CLICK, objectFound);
//**
arrayAphid*.x = Math.random()*stage.stageWidth;
arrayAphid*.y = Math.random()*stage.stageHeight;
//arrayAphid*.scaleX = arrayAphid*.scaleY = Math.random();


arrayAphid*.gotoAndPlay(Math.ceil(Math.random()*15));

}

//**
function objectFound(e:MouseEvent):void
{
var _found:int = arrayAphid*;
var aphids:MovieClip = e.currentTarget as MovieClip;
aphids.removeEventListener(MouseEvent.CLICK, objectFound);

// Set the object's visibility to false
aphids.visible = false;


_found--;

//trace('&gt; ' + aphids.name + ': founded');
