Rotating an object 360 & counting revolutions

1

hi my code is bugged …

I want my line (which does) follow the mouse, like a dial.
I have converted the degrees into a percentage, so that when the percentage of the rotation reaches 100%, my script counts one revolution, and adds it to its ‘counter’… it kind of works, but sometimes it gets lost and if I go too fast: it misses the revolution count …

here is my code (with the line being ‘line’ as an MC)…

var degrees:Number = 0;
fixedX = line._x;
fixedY = line._y;
var radians:Number;
var angles:Number;
var counter:Number = 0;
var revolution:Number = 0;
var Last:Number = 0;
var percent:Number = 0;
onEnterFrame = function()
{
    radians = Math.atan2(_ymouse-fixedY,_xmouse-fixedX);
    angles = radians*180/Math.PI;
    
    angles += 90;
    
    line._rotation = angles ;
    percent = Math.round(((angles+90)/360)*100);
    angels.text = percent;
    if     (percent > Last)
    {
        counter = percent;
        last.text = "last percent " + Last;
        counta.text = "counter "+counter;
        Last = percent+1;
        if (counter >= 100)
        {
            revolution ++;
            counter -= percent;
            Last = 0;
        }
    }
    rev.text = "revs = " + revolution;
}

Any help would be appreciated!
