Question

i am having trouble understanding how to dispatch events and where to catch them. currently i have a document class waterMain, and another class called gunner. my waterMain createds a object of gunner and adds it as child, in my gunner there is a function firebullet, in it i dispatch a

dispatchEvent(new Event(“bulletFired”));

and from my waterMain class i do a

    addEventListener("bulletFired", bulletFiredHandler); 
    private function bulletFiredHandler(e:Event):void       
{           
hudMenu.reduceBullet();         
}

the hudMenu is a variable on the waterMain document class, however it seems that nothing is happening. is the waterMain class not catching the dispatched event?

package  
{
    import flash.display.MovieClip;
    import flash.display.Stage;
    import flash.events.Event;
    import flash.events.MouseEvent;
    import flash.geom.Point;
    /**
     * ...
     * @author ...
     */
    public class Gunner extends MovieClip
    {
        private var _stageRef:Stage;
        public var barrel:MovieClip;
        public var point:MovieClip;
        public var _hudMenu:HUD;

        public function Gunner(stageRef:Stage) 
        {   

            //trace("current rotation" + barrel.rotation);
            //barrel.rotation = -90;
            _stageRef = stageRef;
            addEventListener(Event.ENTER_FRAME, rotateTurret);
            _stageRef.addEventListener(MouseEvent.MOUSE_DOWN, fireBullet);


        private function rotateTurret(evt:Event):void 
        {
            //calculations, distance, angle etc
            var a:Number = _stageRef.mouseX - x;
            var b:Number = _stageRef.mouseY - y;
            var angRad:Number = Math.atan2(b, a);
            var angDeg:Number = (angRad * 180 / Math.PI);
            //trace(angDeg );

            barrel.rotation = (angDeg);
        }
        private function fireBullet(mouseEvt:MouseEvent):void
        {

            dispatchEvent(new Event("bulletFired"));
            _stageRef.addChildAt(new Bullet(_stageRef,x, y , new Point(mouseEvt.stageX, mouseEvt.stageY), _koiArray, _lionArray), 1);
            _stageRef.addChild(_stageRef.addChild(this));
        }
    }

}

You need to add the event to the gunner class something like this:

gunner.addEventListener("bulletFired", bulletFiredHandler);

The gunner class is already a EventDispatcher subclass, if I read your question correctly.
