Converting codes[as2 to as3]

programming flash

hello i need some help converting the as2 into as3

here is the code:


var bulletOffset:Number = 10; //pixels - bigger number = less acurate
var bulletLifeTimerTotal:Number = 20; //fps
var bulletSpeed:Number = 10; //pixels
var reloadSpeed:Number = 200; //ms 1000 = 1 second

//Declare variables that we're going to be reusing
//(this saves them in memory thus speeding everything up a little)
var reloadTimer:Number;
var reloadComplete:Boolean = true;
var bulletAngle:Number;
var randomNum:Number;
var playerX:Number;
var playerY:Number;
var rotationDirection:Number;

/**
*
* Fire Weapon
*
*/
function fireWeapon():Void
{
	//check if weapon is reloaded, if true, fire bullet
	if(reloadComplete == true)
	{
		//attach bullet
		var bullet_mc:MovieClip = _root.attachMovie("bullet", "b"+_root.getNextHighestDepth(), _root.getNextHighestDepth());
	
		//position bullet on player
		bullet_mc._x = player_mc._x;
		bullet_mc._y = player_mc._y;
		
		bullet_mc.bulletLifeTimer = 0;
		
		//calculate random bullet offset.
		randomNum = random(bulletOffset)-(bulletOffset/2);
	
		//set bullet firing angle
		bulletAngle = ((player_mc._rotation+randomNum-90)*Math.PI/180);
		bullet_mc.xSpeed = Math.cos(bulletAngle)*bulletSpeed;
		bullet_mc.ySpeed = Math.sin(bulletAngle)*bulletSpeed;
	
		//make it move
		bullet_mc.onEnterFrame = function() {
			//move bullet             
			this._x += this.xSpeed;
			this._y += this.ySpeed;
			//
			//check if  bullet needs to die of old age
			if (this.bulletLifeTimer>=bulletLifeTimerTotal) {
				this.removeMovieClip();
			}
			//update bullet timer 
			this.bulletLifeTimer++;
		};
		//start reloading gun
		startReloading();
	}
}

//start reloading weapon 
function startReloading()
{
	reloadComplete = false;
	//set a timer that will call the gunReloaded function after "reloadSpeed" time passes
	reloadTimer = setInterval(this, "gunReloaded", reloadSpeed);
}
//gun reloaded function - clears timers and sets reloaded to true
function gunReloaded()
{
	clearInterval(reloadTimer);
	reloadComplete = true;
	
}
