Ok, im trying to grasp how functions and motion tweening works.

Heres my question. How do i make an object move along the y axis once it has reached its x axis target?

HEre is the code, that i got from here.

and what in this code is making the MC ease out?

```auto

MovieClip.prototype.move = function() {
endX = 202;
this._x += Math.round((endX-this._x) >> 1);
 
delete this.onEnterFrame;
};

```
