     // audio
 private PlayerController audio;
 private AudioClip clip;
     if(other.tag == "Player")
     {
         HealthManager.HurtPlayer(damageToGive);
         //soundEffect.Play();

         clip = audio.getSound(2);

         GetComponent<AudioSource>().clip = clip;
         GetComponent<AudioSource>().Play();

         Debug.Log("play");
     }
