Unity почему OnTriggerStay вызывает много лагов?

private void OnTriggerStay(Collider other)
    {
        if (enemy == null)
        {
            if (other.gameObject.tag == "Crip")
            {
                if (other.gameObject.GetComponent<Crip>().isMyTeam != gameObject.GetComponent<Crip>().isMyTeam)
                {
                    enemy = other.transform;
                    prior = Priority.Enemy;
                }
            }
            else
                return;
        }
        else
            return;
    }
