Mouse activated scrolling navigation in Flash MX

Hello,

I’m trying to create a vertical navigation bar that scrolls back and forth along the y axis in response to the movement of the mouse.  There is a catch, however… It can only scroll when the mouse is over the navigation.  I have other objects elsewhere on the stage that respond to mouse movements and I’ve found that it can be quite distracting to have the navigation scrolling while I navigate other parts of the stage.  


Here’s the script which is applied to the navigation mc:

onClipEvent (load)
{
   ycenter=175;
   speed=1/20;
}
onClipEvent (enterFrame)
{
   var distance=_root._ymouse-ycenter;
   _y-=(distance*speed);
   if (_y > 0) _y=-513;
   if (_y < -513) _y=0;
}

My question is, how should I modify this code so that the navigation only scrolls while the mouse is over it.

Expert assistance is always appreciated.

Thanks

make the scrolling conditional on the mouse touching the movieclip..

onClipEvent (enterFrame){
      if (hitTest( _root._xmouse, _root._ymouse, false)){
      var distance=_root._ymouse-ycenter;
   _y-=(distance*speed);
   if (_y > 0) _y=-513;
   if (_y < -513) _y=0;
      }
}

and of course you could do it with a function as well..

onClipEvent (enterFrame){
this.onRollOver = function () {
var distance=_root._ymouse-ycenter;
   _y-=(distance*speed);
   if (_y > 0) _y=-513;
   if (_y < -513) _y=0;
     }
}
