in my Main class I have:


        private function bulletkill(obj:Bullet):void
            {


           obj.removeChild(obj);
        //  BulletList.splice(obj, 1);



            }

        //ENTERFRAME FUNCTION
        function update(e:Event)
            {
                //move the ship
                ship.move(e);

                //make the bullet move
                for each (bullet in BulletList)
                {

                        bullet.move(e);
                        if (bullet.y > 100)
                        bulletkill(bullet);

                }

in my ship class i have:

    private var environment:Engine;

        if (key.isDown(Keyboard.SPACE)&& controlaBalas>8)
                    {
                        //create bullet
                        var b:Bullet = new Bullet();
                        //set pos
                        b.x = this.x-4;
                        b.y = this.y - 14;
                        //control bullets
                        controlaBalas = 0;
                        //save into array
                        //environment.BulletList.push(b);

                        environment.addChild(b);

                        //go to stage
                        //stage.addChild(b);
                    }
