creating limits with variables

i need to know how to create limits for an animation i have created.
the script is as folows
rolly._x=_xmouse
with rolly being the instance name of my movie clip.
now i only want the object to follow the mouse in a certain area not the entire movie .
if anyone out there could help with this please get back to me .
cheers.

This kinda tricky way to do this...
Make a blank frame (I mean empty) with action stop() in your rolly, name frame "hide_cur" (just for hiding the dragged clip) and then...
Place this script in your rolly:

Code:

---

onClipEvent(enterFrame){
        Mouse.hide();
        xTarget = _root._xmouse;
        yTarget = _root._ymouse;
    // here You can change the limits
        if ((xTarget>690) || (xTarget<100) || (yTarget>290) || (yTarget<1)){
                Mouse.show();
                this.gotoAndPlay("hide_cur");
                _y += (yTarget-_y);
                _x += (xTarget-_x);
        } else {
        this.gotoAndPlay(1); // or any with the content...
        _y += (yTarget-_y);
        _x += (xTarget-_x);
}
}

It`s seems to be little bit complicated, but it works...
Or You can use :

Code:

---

_root.rolly.startDrag( True, left_limit, top_limit, right_limit, bottom_limit );
