void Update () {
        if (Input.GetKeyDown("left"))
        {
        gameObject.transform.Translate(-50f*Time.deltaTime,0,0);
        gameObject.GetComponent<Animator>().SetBool("moving",true);
        gameObject.GetComponent<SpriteRenderer>().flipX = true;
        }
        if (Input.GetKeyDown("right"))
        {
        gameObject.transform.Translate(50f*Time.deltaTime,0,0);
        gameObject.GetComponent<Animator>().SetBool("moving",true);
        gameObject.GetComponent<SpriteRenderer>().flipX = false;
        }
        {
        else
        gameObject.GetComponent<Animator>().SetBool("moving",false);

        }

    }
