Mi ennek az Action Script 2es kódnak az AS3-as megfelelője?

A kód:

var scrollUpper:Number = 263;

var scrollLower:Number = 316;

var textLower:Number = 369;

var textUpper:Number = 252;

var scrollRange:Number = scrollLower - scrollUpper;

var textRange:Number = textLower - textUpper;

function scroll() {

var moved:Number = scroll_mc._y - scrollUpper;

var pctMoved:Number = moved/scrollRange;

var textMove:Number = pctMoved*textRange;

szoveg_mc._y = textLower - textMove;

}

scroll_mc.onPress = function () {

this.startDrag(false,this._x,scrollUpper,this._x,scrollLower);

this.onMouseMove = scroll;

}

scroll_mc.onRelease = scroll_mc.onReleaseOutside = function () {

this.stopDrag();

this.onMouseMove = null;

}
