MC follow mouse click

So I'm trying to do something incredibly simple and It just isn't working properly. I'm annoyed at myself for not being able to find a solution but I need a fresh head on it!

Imagine we have a MovieClip called "box". When I click somewhere on the screen, I want the box MC to move to that position. So I wrote something like this (just for horizontal movement):

PHP Code:

---

onMouseDown=function(){
moveTo(_xmouse);
};

function moveTo(newx){
box.onEnterFrame=function(){
if(box._x<newx){
box._x+=5;
}else if(box._x>newx){
box._x-=5;
}else{
delete box.onEnterFrame;
}
};
} 


---

Now this works to a degree, except that when the box MC moves to the right position, it then proceeds to vibrate on the spot. I thought it was probably because it can never move to the exact position of _xmouse because I'm adding 10 to the x property which is why the condition is never met. However even if I just add 1 instead of 10, I still have the same problem..

Any ideas before I go mad?

Try something like this,...

Actionscript Code:

import mx.transitions.Tween;
import mx.transitions.easing.*;

_root.onMouseDown = function() {
    var tx:Object = new Tween(box, "_x", Regular.easeOut, box._x, _xmouse, 1, true);
    var ty:Object = new Tween(box, "_y", Regular.easeOut, box._y, _ymouse, 1, true);
}

I thought about using the tween class, but didn't know if it would be the most efficient way.

I gave it a go, and it returned this beastly error! :\

Code:

No worries, sorted it! Wrote a tween script from scratch.. and it worked :\

Code:

---

function walkTo(newX, newY) {
        var xMove:Object = new Tween(girl, "_x", Regular.easeOut, girl._x, newX, 10, UseSeconds);
        xMove.onMotionFinished = function() {
                var yMove:Object = new Tween(girl, "_y", Regular.easeOut, girl._y, newY, 10, UseSeconds);
        };
}
