As3: Bullet giving me errors? - actionscript-3

Question

I have an enemy class which spawns bullets at the player.
private function fireBullet()
{
if(isFiring)
{
fire();
}
}
public function fire():void
{
var bullet:Bullet = new Bullet(x, y, rotation);
stage.addChild(bullet);
}
And in the bullet class:
package {
import flash.display.MovieClip;
import flash.events.Event;
public class Bullet extends MovieClip {
private var _root:MovieClip;
private var isVanished:Boolean = false;
public function Bullet(x:int, y:int, rotation:Number)
{
this.x = x;
this.y = y;
this.rotation = rotation;
_root = MovieClip(root);
addEventListener(Event.ENTER_FRAME, loop);
}
private function loop (event:Event):void
{
if(this.hitTestObject(_root.assassin.hitbox))
{
_root.hitPoints -= 30;
}
else
{
y-=Math.cos(rotation/-180*Math.PI)*(15);
x-=Math.sin(rotation/-180*Math.PI)*(15);
}
if(this.x < 0 || this.x > _root.stageWidth || this.y > _root.stageWidth || this.y < 0)
{
removeChild(this);
removeEventListener(Event.ENTER_FRAME, loop);
}
}
}
}
However, when I start the game, I get a 1009 error regarding line 23, and the game slows down rapidly as the bullets don't even move.
I also get an 1063 error, expecting 3 but having 0.
ArgumentError: Error #1063: Argumentblabla for Bullet(). Expected 3 but 0 were shown. ((translated))
at flash.display::Sprite/constructChildren()
at flash.display::Sprite()
at flash.display::MovieClip()
at Main()[C:\Venture Inc\Main.as:189]
This is what main looks like
//Constructor
public function Main()
{
addChild(container_staff);
addChild(container_wall);
etc etc etc

ArgumentError: Error #1063: Argumentblabla for Bullet(). Expected 3 but 0 were shown. ((translated))
Bullet class constructor has 3 arguments. Check your code more precisely, I think you have something like this:
var bullet: Bullet = new Bullet();
Also there is problem with your code. Every bullet subscribes for the ENTER_FRAME. Centralize your game, create main loop, and update all game actors(bullets, enemies, etc) from there.
