Resources.LoadAll(); GameObject[] Array

Question

Here is my question:

 using UnityEngine;
 using System.Collections;
 
 public class Hajawack : MonoBehaviour {
     GameObject[] objMatToCompTo;
     // Use t$$anonymous$$s for initialization
     void Start () {
         objMatToCompTo = Resources.LoadAll("(1)BlockPreFab", typeof(GameObject)) as GameObject[];
     }
     
     // Update is called once per frame
     void Update () {
         Debug.Log(objMatToCompTo[0].name);
     
     }
 }

Debug.Log, instead of printing, gives me the error:

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

What should i do?

Assuming you have folder (1)BlockPreFab under Assets\\Resources, then Resources.LoadAll probably works ok, but converting result messes t$$anonymous$$ngs up. You can't convert Object[] to GameObject[]. You have to do your casting differently, for example using LINQ:

 objMatToCompTo = Resources.LoadAll("(1)BlockPreFab", typeof(GameObject))
     .Cast<GameObject>()
     .ToArray();

Additionally you need to add

 using System.Linq;

on top of your script.
