Problem with timeout translation from AS2 to AS3

Hi guys I’m trying to change this piece of code to AS3 and am having problems with the _root from AS2. The code changes the position of movie clip if there is no mouse movement for 20 sec’s. any help with translation would be greatly appreciated.

//BACK TO START TIMEOUT
function idleTime( ) {

// Play the attract animation

//trace(“playing the animation”)

var titleTween:Tween = new Tween (bigMc,"x", Strong.easeOut, bigMc.x, 600, 2, true);
var titleTween:Tween = new Tween (bigMc,"y", Strong.easeOut, bigMc.y, 400, 2, true);

//titleTween.onMotionFinished = function () {
//menuMC._y = 543;
//newx = 600;
//newy = 400;

    //}

}

function idleS( ) {

// See if there has been any mouse movement in the last two seconds

if ((_root._xmouse + _root._ymouse) != mousePos) {

// If there has, restart the check for the idle timer

//trace("resetting");



clearInterval(idle);

idle = setInterval(idleTime, 20000);

//} else {

//trace("no movement this period");

}

// Store an integer representing the mouse position

mousePos = _root._xmouse + _root._ymouse;

}

function startIdle( ) {

mousePos = -100000; // Initialize it to a dummy value

idleSample = setInterval(idleS, 2000);

}

startIdle( );

stop( );

Thanks In Advance.
