"Interactive Image Panning" tutorial HELP!

1

ok hello everyone! I’m new on the forum and at using action script.

ok … now my question:

I’ve done the “[COLOR=black]**Interactive **Image Panning” tutorial on kirupa.com using [COLOR=red]Flash 8[/COLOR] and I understand all of it’s code.[/COLOR]
Now I want to use this technique for one of my project but with something diferent:

I wonder if it’s possible for the background to pan only when the mouse is in the “red” zones … pan to the left when in the left zone and to the right when in the right zone. I don’t know if I have to use the mouseOver or anything else. See the image for the “zones”:

There is the actual code after doing the tutorial:

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 == 2) {
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 if (target._x>target.destX) {
target._x -= Math.ceil((target._x-target.destX)(speed/100));
} else if (target._x<target.destX) {
target._x += Math.ceil((target.destX-target._x)*(speed/100));
}
};
}

I would like to use the same attribute like the speed and everything if possible.

Thanks in advance !!!
