i have been trying to convert as2 code to as3 for scrollbar. and i managed to do everything except startDrag.  
so basicly i want to be able to drag mc called _drag_ but i need x coordinates to remain same only y coordinates should change.  
I have been reading tutorials and help file for about 3-4 h now and still dont understand how to do it.  
everything works just fine if i dont try to make it move only on y and that x remains same(if i put only startDrag()😉

this part is what needs to be changed (i think)

function fonpress(event:MouseEvent):void {  
drag.startDrag(true, Mysprite);  
}

var mySprite:Sprite = this.drag();  
this.addChild(mySprite);  
drag.addEventListener(MouseEvent.MOUSE\_DOWN, fonpress ) ;

and this is how it looked in as2  
startDrag(this, false, drag.\_x, min\_y, drag.\_x, max\_y);

here is the full code:

```auto
/////////////////////////////////////////////////////////

 import fl.transitions.Tween;
 import fl.transitions.easing.*;
 import flash.events.MouseEvent;
 import flash.display.Sprite;

var animacija_skrola:Boolean = true; // kasnjenje scrolla DA/NE
var time:Number =50; // kasnjenje u milisekundama
        // y pomak kod skrola 

/////////////////////////////////////////////////////////

sadrzaj.mask = maska;
drag.y = maska.y; // pocetna pozicija - drag
var min_y:Number = maska.y;
var max_y:Number = maska.y+maska.height-drag.height;    
var dy:Number = maska.height-drag.height;
var d_height:Number = sadrzaj.height-maska.height;

function fdrag(event:Event):void {
    
    var pozicija:Number = Math.round(maska.y-d_height*(drag.y-min_y)/dy);
    if (animacija_skrola == false) {
        sadrzaj.y = pozicija;
    } else {
         var motion:Tween = new Tween(sadrzaj, "y", Strong.easeOut, sadrzaj.y, pozicija, time, false);
    }
}
this.addEventListener(Event.ENTER_FRAME, fdrag);

//////////////////////////////////////////////////////////////////

function fonpress(event:MouseEvent):void {
    drag.startDrag(true, Mysprite);
}

var mySprite:Sprite = this.drag();
this.addChild(mySprite);
drag.addEventListener(MouseEvent.MOUSE_DOWN,fonpress);

function fonrelease(event:MouseEvent):void {
    drag.stopDrag(true, Mysprite);
    drag.alpha=30;
}
drag.addEventListener(MouseEvent.MOUSE_UP,fonrelease);

function fdragover(event:MouseEvent):void {
    drag.alpha=100;
}
drag.addEventListener(MouseEvent.MOUSE_OVER ,fdragover);

function fdragout(event:MouseEvent):void {
    drag.alpha=30;
}
drag.addEventListener(MouseEvent.MOUSE_OUT,fdragout);
