I need some help with an error pls?

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:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6.  
7.  
8. public class LevelManager : MonoBehaviour
9. {
10.  
11.     public GameObject currentCheckpoint;
12.     //Player GameObject
13.     //aktueller Checkpoint
14.     public GameObject player;
15.     //Lebensanzeige
16.     public int lives;
17.     public Text livesText;
18.  
19.     private void Start()
20.     {
21.         LivesText.text = "Lives: " + lives.ToString();
22.     }
23.  
24.     private void Update() {
25.  
26.         if (Input.GetKeyDown(KeyCode.Escape)) {
27.             Debug.Log("Game ends!");
28.             Application.Quit();
29.         }
30.   }
31.  
32.  
33.     public void RespawnPlayer()
34.     {
35.         // Leben abziehen
36.         lives = lives - 1;
37.         //Lebensanzeige aktualisieren
38.         LivesText.text = "Lives: " + lives.ToString();
39.         //Überprüfen ob Spieler noch Leben hat
40.         if(lives > 0)
41.         {
42.             player.transform.position = currentCheckpoint.transform.position;
43.         }
44.         else
45.         {
46.             Time.timeScale = 0.0f;
47.             Debug.Log("Game over!");
48.         }
49.  
50.         //falls ja -> Respawn
51.         //falls nein -> Spielende
52.  
53.  
54.         // Spieler an die Postition des Checkpoints bringen.
55.    
56.     }
57. }
58.  

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
