Question by Giibl3ts · Sep 15, 2015 at 12:53 AM · gameobjectarrayposition

Position Array Returning null reference

First time asking a question but i cannot figure it out... I have a script ( below ) that is getting every gameobject with the tag cage and storing them into an array. Next i want it to get there position and store that into another array but i am getting a null reference exeption... In my scene I have 9 cages in total each at different x positions and yes they do have the cage tag and i can debug.log that and the array does list the 9 cages. The problem is when i try to get the positions. here is my code. thanks in advance

 private GameObject[] Cages;
 private Vector3[] CagesPos;

 public void Start()
 {
     Cages = GameObject.FindGameObjectsWithTag("Cage");

     for (int i = 0; i < Cages.Length; i++)
     {
         Cages[i].transform.position = CagesPos[i];  //this is the line throwing null reference 
     }
 }

Please help!!

If you want to save the value to CagesPos shouldn't be CagesPos[i] = Cages[i].transform.position; instead Cages[i].transform.position = CagesPos[i];

 private GameObject[] Cages;
     private Vector3[] CagesPos;
     public void Start()
     {
         Cages = GameObject.FindGameObjectsWithTag("Cage");
         CagesPos = new Vector3[Cages.Length];
         for (int i = 0; i < Cages.Length; i++)
         {
             //Cages[i].transform.position = CagesPos[i];
             CagesPos[i] = Cages[i].transform.position;
         }
     }
