heres KillPlayer Script:
using UnityEngine;
using System.Collections;

public class KillPlayer : MonoBehaviour
{

public LevelManager levelManager;

// Use this for initialization
void Start()
{
    levelManager = FindObjectOfType<LevelManager>();
}

// Update is called once per frame
void Update()
{

}

void OnTriggerEnter2D(Collider2D other)
{
    if (other.name == "Player")
    {
        levelManager.RespawnPlayer();
    }
}

}
heres LevelManger script:
using UnityEngine;
using System.Collections;

public class LevelManager : MonoBehaviour
{

public GameObject currentCheckpoint;

private CharacterController player;

// Use this for initialization
void Start()
{
    player = FindObjectOfType<CharacterController>();
}

// Update is called once per frame
void Update()
{

}

public void RespawnPlayer()
{
    Debug.Log("Player Respawn");
    player.transform.position = currentCheckpoint.transform.position;
}

}

heres Checkpoint Script:
using UnityEngine;
using System.Collections;

public class Checkpoint : MonoBehaviour
{
public LevelManager levelManager;
// Use this for initialization
void Start()
{
levelManager = FindObjectOfType();
}

// Update is called once per frame
void Update()
{

}

void OnTriggerEnter2D(Collider2D other)
{
    if (other.name == "Player")
    {
        levelManager.currentCheckpoint = gameObject;
    }
}

}

The error happens here.

Either player is null or currentCheckpoint is null.

 public void RespawnPlayer()
 {
     Debug.Log("Player Respawn");
     player.transform.position = currentCheckpoint.transform.position;
 }

Fix it by first checking which one of them are null and then figure out why they are null, and make sure they aren’t null.

Try Debug.Log("Player " + player); and Debug.Log("Checkpoint " + currentCheckpoint); and read the console to further narrow the problem down.

Perhaps you haven’t entered a checkpoint yet.

bro

public void RespawnPlayer()
{
Debug.Log("Player " + player);
player.transform.position = currentCheckpoint.transform.position;
} I
`
I’ve did it in LevelManager but it’s same thing… Same Error… :frowning:
