    void Update() {
        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) {
            Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
            transform.Translate(-touchDeltaPosition.x * speed, -touchDeltaPosition.y * speed, 0);

        int i = 0;
        while (i < Input.touchCount) {
            if (Input.GetTouch(i).phase == TouchPhase.Began) {
                Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(i).position);
                if (Physics.Raycast(ray))
                    Instantiate(particle, transform.position, transform.rotation) as GameObject;
