Question by CreationAl3xStudio · Aug 21, 2020 at 02:30 PM · nullreferenceexceptionnullsingletonnullreferenceexeption

NullReferenceException: Object reference not set to an instance of an object error

This is my script : using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

public class GameManager : MonoBehaviour {

 public bool isPaused;

 public List<Item> items = new List<Item>();
 public List<int> itemNumbers = new List<int>();
 public GameObject[] slots;
 public Dictionary<Item, int> itemDict = new Dictionary<Item, int>();
 public static GameManager instance;
 private void Awake()
 {
     if (instance != null && instance != this)
     {
         Destroy(gameObject);

     }
     else
     {

         instance = this;        
     }
     DontDestroyOnLoad(gameObject);
 }






         private void Start() => Displayitems();
 private void Displayitems()
 {
     for (int i = 0; i < items.Count; i++)
     {   //UPDATE slots Item Image
         slots[i].transform.GetChild(0).GetComponent<Image>().color = new Color(1, 1, 1, 1);
         slots[i].transform.GetChild(0).GetComponent<Image>().sprite = items[i].itemSprite;
        //UPDATEE slots Count Text
         slots[i].transform.GetChild(1).GetComponent<Text>().color = new Color(1, 1, 1, 1);
         slots[i].transform.GetChild(1).GetComponent<Text>().text = itemNumbers[i].ToString();
        //UPDATE CLOSE/THROW button
         slots[i].transform.GetChild(2).gameObject.SetActive(true);


     }
 }


} All it does is it holds the isPausedvariable that is used by another script, which works , and its doing the display of the items in my inventory, wich it apparantely cant do , and im getting the null error...?
