Make instantiated prefabs the children of another gameObject

Hi, thanks for the reply. And you're right, this was the problem.

There is another error I'm getting to do with the movement of the the parent object's transform. Or rather it's lack of movement. I think it would be best if I showed you the whole code:

 using UnityEngine;
 using System.Collections;
 
 public class itemSpawn : $$anonymous$$onoBehaviour {
     
     private GameObject parentObj;
     public GameObject items;
     public Vector3 spawnPos = new Vector3(5,5,5);
     private int cLine$$anonymous$$ax = 2; //max spawn int
     private float dist = 1.5f;
     
     // Use this for initialization
     void Start () {
         
         //parentObj.AddComponent<Rigidbody>();
         
         for(int i=0; i<cLine$$anonymous$$ax; i++)
         {
             for(int j=0; j<cLine$$anonymous$$ax; j++)
             {
                 for(int k=0; k<cLine$$anonymous$$ax; k++)
                 {
                     
                     GameObject parentObj = Instantiate(items, new Vector3 (spawnPos.x + i*dist, spawnPos.y + j*dist, spawnPos.z + k*dist), Quaternion.identity) as GameObject;
                     //Instantiates the items into a parent gameobject
 
                 }
             }
         }
         
         //
         
     }
     
 
     void FixedUpdate () {
         parentObj.transform.Rotate(Vector3.right * Time.deltaTime);
     }
 }    

The items just do nothing. I really appreciated the help so far, do you have any ideas what the problem could be from the code?

Additional note: There items are spawned into a giant cube of individual objects. I'm trying to get this to rotate constantly. Thought it might help to have some context.

You are declaring parentObject as a local in your loop, so the global never gets set. Get rid of the declaration in the loop and just set it.

This:

 GameObject parentObj = Instantiate(items, new Vector3 (spawnPos.x + i*dist, spawnPos.y + j*dist, spawnPos.z + k*dist), Quaternion.identity) as GameObject;

Should just be:

 parentObj = Instantiate(items, new Vector3 (spawnPos.x + i*dist, spawnPos.y + j*dist, spawnPos.z + k*dist), Quaternion.identity) as GameObject;

Thanks for the reply! This worked for me. It's led to a newer problem, but I think I can tackle this one myself.

$$anonymous$$uch appreciated!
