Loved writing code since I started a couple months ago, and I get pissed to see the lack of useful tutorials for widely used subjects on the web.

And for those of you that didn't read the Shooting bullets tutorial, here is the unbroken code:

var bullet_array:Array= new Array();
var bulletSpeed:Number = 5;
var xSpeed:Number = 0;
var ySpeed:Number = 0;
var reloadSpeed:Number = 100;//milliseconds
var bulletOffset:Number = 10;//pixels
var randomNum:Number = 0;
var life:Number = 0;
var totalLife:Number = 50;//frames
var reloaded:Boolean = true;
var x:Number = 0;
turret.onEnterFrame = function() {
    if (Key.isDown(Key.LEFT)) {
        this._rotation -= 5;
    }</p>
<p>    if (Key.isDown(Key.RIGHT)) {
        this._rotation += 5;
    }</p>
<p>    if (Key.isDown(Key.SPACE)) {
        fire();
    }</p>
<p>};
function fire() {
    if (reloaded) {
        x = _root.getNextHighestDepth();
        bullet_array.push("bullet"+x);
        var bullet:MovieClip = _root.attachMovie("bullet", "bullet"+x, x);
        bullet._x = turret._x;
        bullet._y = turret._y;
        randomNum = random(bulletOffset)-bulletOffset/2;
        bullet._rotation = turret._rotation+randomNum;
        bullet.xSpeed = Math.cos(Math.PI/180*bullet._rotation)*bulletSpeed;
        bullet.ySpeed = Math.sin(Math.PI/180*bullet._rotation)*bulletSpeed;
        bullet.life = 0;
        bullet.onEnterFrame = function() {
            this._x += this.xSpeed;
            this._y += this.ySpeed;
            this.life++;
            if (this.life>totalLife) {
                this.removeMovieClip();
                this.unloadMovie();
            }</p>
<p>        };
        reload();
    }</p>
<p>}</p>
<p>function reload() {
    reloaded = false;
    timer = setInterval(this, "Reloaded", reloadSpeed);
}
function Reloaded() {
    clearInterval(timer);
    reloaded = true;
}
for (x=0; x<10; x++) {
    attachEnemy();
}
function attachEnemy() {
    x = _root.getNextHighestDepth();
    var enemy:MovieClip = _root.attachMovie("enemy", "enemy"+x, x);
    enemy._x = random(Stage.width);
    enemy._y = random(Stage.height);
    enemy.onEnterFrame = function() {
        for (x in bullet_array) {
            if (this.hitTest(_root[bullet_array[x]])) {
                _root[bullet_array[x]].removeMovieClip();
                this.removeMovieClip();
                bullet_array.splice(x,1);
            }
        }
    };
}
