scrolling text

[cancerinform]

I had only made a suggestion. The implementation is more complex:

var isScroll:Boolean;
function mouseDownScroll (e:MouseEvent)
{
    isScroll = true;
    function downscroll (e:Event)
    {
        if (!isScroll)
        {
            e.target.removeEventListener (Event.ENTER_FRAME, downscroll);
        }
        e.target.scrollV++;
    }
    textBox.addEventListener (Event.ENTER_FRAME, downscroll);
}


function mouseUpscroll (e:MouseEvent)
{
    isScroll = true;
    function upScroll (e:Event)
    {
        if (!isScroll)
        {
            e.target.removeEventListener (Event.ENTER_FRAME, upScroll);
        }
        e.target.scrollV--;
    }
    textBox.addEventListener (Event.ENTER_FRAME, upScroll);
}

function mouseUpEvent (e:MouseEvent)
{
    isScroll = false;
}
upButtonContact.addEventListener (MouseEvent.MOUSE_DOWN, mouseDownScroll);
downButtonContact.addEventListener (MouseEvent.MOUSE_DOWN, mouseUpscroll);
addEventListener (MouseEvent.MOUSE_UP, mouseUpEvent);
