NullReference when accessing GameObject in array (C#)

Questions & Answers

Hello! I am new to Unity and I need help. I try to instantiate a prefab into anto an array of GameObjects and then use it from that array.
Here is my code:

public class TestScript : MonoBehaviour
{    
		public Transform somePrefab;
		GameObject[] testArray;

		void Start ()
		{
				testArray = new GameObject[5];
				CreatingObjects ();
				AssignNames ();
		}
	
		void CreatingObjects ()
		{
				for (int i = 0; i < 5; i++) {
						testArray  *= Instantiate (somePrefab) as GameObject;    						*

  •  		}*

  •  }*

  •  void AssignNames ()*

  •  {*

  •  		for (int i = 0; i < 5; i++)*

_ testArray .name = "Cube # " + i;_
* }*
}

Probles is that I get an NullReferenceException error on line 28 (23 here):
*NullReferenceException: Object reference not set to an instance of an object
TestScript.AssignNames () (at Assets/Scripts/TestScript.cs:28)
TestScript.Start () (at Assets/Scripts/TestScript.cs:14)*
What am I doing wrong?

Hi! “name” is a property of Gameobject, and you are instantiating a Transform.

Change

public Transform somePrefab;

by:

public GameObject somePrefab;

or change this:

testArray  *= Instantiate (somePrefab) as GameObject;*

by this:
testArray = Instantiate (somePrefab.gameObject) as GameObject;
