1136: Wrong Number of Arguments

Question

Hi,
I'm a flash beginner and I wanted to do a "Space Invaders" like game. Now I get an error, wehn I try to call a function in an other function.is that not allowed? I want that the Bullet shoots directly when I click. but when I hold the left mouse button pressed, the mode should be auto shoot and bullets should shoot out with a timer of 100. I got sucsess by writing both in the start shoot timer, like this:
public function startShootTimer (e:MouseEvent):void {
            ShootTimer.start();
            var bullet:Bullet = new Bullet();
            bullet.x = bazooka.x + 70;
            bullet.y = bazooka.y - 3;
            addChild(bullet);
            Bullets.push(bullet);
But it would be better (for future projects) to have 2 functions, or not ? Is that possible ? Very thank you for your help ! Here's my full not working program:
package  {
    import flash.display.*;
    import flash.events.Event;
    import flash.utils.Timer;
    import flash.events.MouseEvent;
    import flash.events.TimerEvent;
    public class Main extends MovieClip {
        var bazooka:Bazooka = new Bazooka();
        var Bullets:Array = new Array();
        var ShootTimer:Timer = new Timer(500);
        public function Main() {
            startGame();
        public function startGame() {
            addPlayer();
            stage.addEventListener(Event.ENTER_FRAME, mainLoop);
            ShootTimer.addEventListener(TimerEvent.TIMER, autoShootBullet);
            stage.addEventListener(MouseEvent.MOUSE_DOWN, startShootTimer);
            stage.addEventListener(MouseEvent.MOUSE_DOWN, shootBullet);
            stage.addEventListener(MouseEvent.MOUSE_UP, stopShootTimer);
        public function addPlayer():void {
            bazooka.x = 0;
            bazooka.y = stage.stageHeight * .5;
            addChild(bazooka);
        public function shootBullet(e:MouseEvent):void {
            var bullet:Bullet = new Bullet();
            bullet.x = bazooka.x + 70;
            bullet.y = bazooka.y - 3;
            addChild(bullet);
            Bullets.push(bullet);
        public function startShootTimer (e:MouseEvent):void {
            ShootTimer.start();
        public function stopShootTimer (e:MouseEvent):void {
            ShootTimer.stop();
        public function autoShootBullet (e:TimerEvent):void {
            shootBullet();      // Heres my error
        public function mainLoop (e:Event):void {
            for (var b:int = 0; b < Bullets.length; b++) {
                Bullets[b].x += 20;

Answer 1

that's allowed.
but your shootBullet function expects a mouse event to be passed as a parameter.  there are two quick and easy ways to resolve:
1.  use shootBullet(null)
2.  change your shootBullet function to:
  public function shootBullet(e:MouseEvent=null):void {
            var bullet:Bullet = new Bullet();
            bullet.x = bazooka.x + 70;
            bullet.y = bazooka.y - 3;
            addChild(bullet);
            Bullets.push(bullet);
