Dynamically generated movieClipS hitTesting

So I’m doing a little project that requires movie clips to be created through action script.

Im not sure how to get them to hitTest because they are both created in seperate functions.


//Enemy function
newEnemy = function () {
    var Enemy = _root.attachMovie("angryEyes", "angryEyes"+i, _root.getNextHighestDepth());
    Enemy._y = random(550);
    Enemy._x = Stage.width;
    Enemy.onEnterFrame = function() {
        this._x -= random(20);
        this._y += -5+random(10);
        i++;
        if (wall.wall1.hitTest(this)) {
            removeMovieClip(this);
        }
        /*hitTest arrow with zombie!? 
        function shootZombie() {
            if (this.hitTest(angryEyes+i)) {
                trace("hit");
            }
        }*/
    };
};
//Spawn new Enemy at an interval of 800ms
setInterval(newEnemy, 800);
//Function for shooting arrows and their direction 
//(all things related to how they travel and are created)
ShootBullet = function () {
    var Bullet = _root.attachMovie("Bullet", "Bullet"+Num, _root.getNextHighestDepth());
    var point = {x:this.hero.gunTip._x, y:this.hero.gunTip._y};
    this.hero.localToGlobal(point);
    Bullet._x = point.x;
    Bullet._y = point.y;
    Bullet._rotation = _root.hero._rotation;
    Bullet.onEnterFrame = function() {
        Bullet._x += Math.cos(Bullet._rotation*(Math.PI/180))*35-5+random(10);
        Bullet._y += Math.sin(Bullet._rotation*(Math.PI/180))*35-5+random(10);
        //This is so that arrows will clear outside of the stage
        //It seems redundant, should use a switch case? or something
        if (wall.wall1.hitTest(Bullet) == true) {
            removeMovieClip(this);
        }
        if (wall.wall2.hitTest(Bullet) == true) {
            removeMovieClip(this);
        }
        if (wall.wall3.hitTest(Bullet) == true) {
            removeMovieClip(this);
        }
        if (wall.wall4.hitTest(Bullet) == true) {
            removeMovieClip(this);
        }
    };
    //unique identifier for each arrow
    Num++;
    //shows how many how many have been shot
    //trace(Num);
    shootZombie();
};
