              Changing positions of all GameObjects in an array
I am constantly getting a Null Reference error when I try to change the positions of the game objects stored in an array. This is my current code:
 public class Trader : MonoBehaviour
 {
     private GameObject[] traders = new GameObject[9];
     private Vector3[] positions = new Vector3[9];
     void Start()
     {
         for (int i = 1; i < 9; i++)
         {
             GameObject pos = GameObject.Find("Wall"+i);
             GameObject trader = GameObject.Find("Trader" + i);
             this.positions[i] = pos.transform.position;
             this.traders[i] = trader;
            
         }
     }
 
     // Update is called once per frame
     void Update()
     {
         SetPositions();
     }
 
     private void SetPositions()
     {
         int randPos;
         bool[] assigned = new bool[8];
         int count = 0;
 
         while (count < 8)
         {
             randPos = Random.Range(0, 8);
             if (!assigned[randPos])
             {
 
                //error occurs here
                 this.traders[count].transform.position += this.positions[randPos] - new Vector3(0f, 0f, 1f);
                 assigned[randPos] = true;
                 count++;
 
             }
 
             else
             {
                 continue;
             }
 
         }
     }
 }
