I need some help with an error pls?

Unity Engine

Hey,

I´m new to Unity and I´m making a 2D Jump & Run and I try to add lives in the LevelManager, but I always get an error:
NullReferenceException: Object reference not set to an instance of an object
LevelManager.Start () (at Assets/Scripts/LevelManager.cs:20)

That´s my script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;


public class LevelManager : MonoBehaviour
{

    public GameObject currentCheckpoint;
    //Player GameObject
    //aktueller Checkpoint
    public GameObject player;
    //Lebensanzeige
    public int lives;
    public Text livesText;

    private void Start()
    {
        LivesText.text = "Lives: " + lives.ToString();
    }

    private void Update() {

        if (Input.GetKeyDown(KeyCode.Escape)) {
            Debug.Log("Game ends!");
            Application.Quit();
        }
  }


    public void RespawnPlayer()
    {
        // Leben abziehen
        lives = lives - 1;
        //Lebensanzeige aktualisieren
        LivesText.text = "Lives: " + lives.ToString();
        //Überprüfen ob Spieler noch Leben hat
        if(lives > 0)
        {
            player.transform.position = currentCheckpoint.transform.position;
        }
        else
        {
            Time.timeScale = 0.0f;
            Debug.Log("Game over!");
        }

        //falls ja -> Respawn
        //falls nein -> Spielende


        // Spieler an die Postition des Checkpoints bringen.
   
    }
}

when i remove this: livesText.text = lives.ToString(); and LivesText.text = "lives: " + lives.ToString(); the game works.

I pulled it into the LevelManager in the Inspector but it sollt gives me this error.

Please help me :).

Please use code tags when posting code.

Have you assigned livesText in the inspector?

Do you mean pulling the LivesText into the LevelManager? Then yes but it still don´t works.

This post was duplicated (which, btw, you probably shouldn’t do). It’s been solved :slight_smile:
