Hi i just have a question about AS2 arrays and use in games, i am making this game where a bullet(attachedMovieClip) is shot out and passes over a duplicated zombie character(duplicated movie clip) i have made an array for them called zombieArray() and i am trying to run a hitTest between them, heres the code.

iBullet.onEnterFrame = function() {

        this._x += this.xSpeed;
        this._y += this.ySpeed;
        
        for(x in zombieArray){
            if (this.hitTest(_root[zombie[x]])) {
                callGore(this,"head");
                createGibs(this,"head");
                this.removeMovieClip();
                //_root.zombieArray.splice(x, 1); should remove zombie from array
        }
        }

…blah blah the funtion goes on. all the other functions work its just wont register the hit with the movieclips. Pease can someone help me out:(
