How to make player die/respawn on endless runner 3D game

Hi there,

I am making a endless runner game for my uni project and need my player to die when it comes off of the edge of the tiles they are running on. I have looked around for a solution but cant find one.

Does anyone know how make my player die/respawn in this way. I presume it would need to be coded into my player movement script which I have attached.

Thanks`

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
  
 public class PlayerMovement : MonoBehaviour
 {
     private bool turnLeft, turnRight;
     public float speed = 7.0f;
     private CharacterController myCharacterController;
     public GameObject textObject;
     public int scoreCounter = 0;
  
     //Audio Events
     public AK.Wwise.Event coinCollectBeep = null; //Audio
     public AK.Wwise.Event Play_Footstep_Cobble = null; //Audio
     public AK.Wwise.Event Play_Footstep_Concrete = null; //Audio
     public AK.Wwise.Event Play_Footstep_Grass = null; //Audio
  
     // Start is called before the first frame update
     void Start()
     {
         myCharacterController = GetComponent<CharacterController>();
     }
  
     // Update is called once per frame
     void Update()
     {
         turnLeft = Input.GetKeyDown(KeyCode.A);
         turnRight = Input.GetKeyDown(KeyCode.D);
  
         if (turnLeft)
             transform.Rotate(new Vector3(0f, -90f, 0f));
         else if (turnRight)
             transform.Rotate(new Vector3(0f, 90f, 0f));
  
         myCharacterController.SimpleMove(new Vector3(0f, 0f, 0f));
         myCharacterController.Move(transform.forward * speed * Time.deltaTime);
     }
  
     private void OnTriggerEnter(Collider other)
     {
         if(other.gameObject.CompareTag("PickUp"))
         {
             coinCollectBeep.Post(gameObject); //Audio
             other.gameObject.SetActive(false);
             scoreCounter = scoreCounter + 1;
             textObject.GetComponent<Text>().text = "Score : " + scoreCounter;
         }
     }
  
     public void PlayFootstepSound()
     {
         Play_Footstep_Cobble.Post(gameObject);
     }
 }
