target = other.transform
}

      void OnTriggerStay(Collider other)
    {

        if (Input.GetMouseButtonDown(0) && GetComponent<Battler>().attacktimer.fillAmount == 1)
        {
            hitsound.Play();
            Cmdhitgraphic();
            other.GetComponent<Battler>().takedamage(attackDamage);
            other.GetComponent<EnemyControl>().takedamage(attackDamage);

        }
