Tween (nudging a mc)

programming flash
1

Hi guys, my question is fairly straight forward-

I have a very long MC, and when a user moves the cursur to the bottom of the screen (or over a button) I want the mc to roll up (the effect of scrolling with the cursor movement).

I’m using tweenlite and I can make them go to specific locations, but I cant just, lets say, move the mc by an + 100px on the Y.

Here is my script so far:

import gs.TweenLite;
import gs.easing.*
import flash.events.MouseEvent;

stop();

buttonBird.addEventListener(MouseEvent.ROLL_OVER, birdClick);



function birdClick(e:MouseEvent):void
{
    TweenLite.to(background_mc, 3, {x:0, y:-364, ease:Expo.easeOut});
}
