'Interactive Image Pan' tutorial help

1

Hey,

I just did this tutorial ‘Interactive Image Pan’

I completed it with succes, but my question:
Is there a way to make it scroll slowly from the beginning, even before you start rolling over it with your mouse?

I dont want it to stand still when you start the movie.

This is the full Kirupa code:

this.onMouseMove = function() { constrainedMove(bg_mc, 4, 1); }; function constrainedMove(target:MovieClip, speed:Number, dir:Number) { var mousePercent:Number = _xmouse/Stage.width; var mSpeed:Number; if (dir == 1) { mSpeed = 1-mousePercent; } else { mSpeed = mousePercent; } target.destX = Math.round(-((target._width-Stage.width)mSpeed)); target.onEnterFrame = function() { if (target._x == target.destX) { delete target.onEnterFrame; } else { target._x += Math.ceil((target.destX-target._x)(speed/100));}}; }
