Explanation on code

currently trying to read someone’s code but i have problem understanding them due to the different way of coding my teacher used to teach me… can someone kindly explain the code below? appreciate that. :slight_smile:

onClipEvent (load) {
OrigY = _y;
NewY = OrigY;
}
onClipEvent (enterFrame) {
_y += ((NewY-_y)/this._parent.Control.Speed);
}[/COLOR]
