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:

var pozicija:Number = Math.round(maska.y-d_height*(drag.y-min_y)/dy);
if (animacija_skrola == false) {
sadrzaj.y = pozicija;
} else {

}
}
