Moving instantiated objects: what is wrong?

I am trying to do a fairly simple thing, and still failing miserably. I want to randomly generate cubes across a range of space-points and the keep changing their position randomly too. I achieve the first part, creating them, but not the second, which is changing their position. Here is my code:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class MyExample: MonoBehaviour {
5.  
6.     private GameObject[] objectlist;
7.     public GameObject mycube;
8.     private float x, y, z;
9.  
10.  
11.  
12.     // Use this for initialization
13.     void Start () {
14.  
15.         for(int i=0; i<100; i++){
16.             x = Random.Range(-1000F, 1000F);
17.             y = Random.Range(-1000F, 1000F);
18.             z = Random.Range(-1000F, 1000F);
19.  
20.             GameObject newobj = Instantiate(mycube, new Vector3(x,y,z), Quaternion.identity) as GameObject;
21.             newobj.tag = "Test";
22.         }
23.         objectlist = GameObject.FindGameObjectsWithTag("Test");
24.     }
25.    
26.     // Update is called once per frame
27.     void Update () {
28.         foreach(GameObject obj in objectlist)
29.         {
30.             x = Random.Range(-1000F, 1000F);
31.             y = Random.Range(-1000F, 1000F);
32.             z = Random.Range(-1000F, 1000F);
33.             obj.transform.position =new Vector3(x,y,z);
34.         }
35.     }
36. }

Does anyone know why this code is not making the instantiated cubes change their position randomly, as expected? Many thanks!

 

Hi, I just check your code and everything works well. May be it's problem with scale or camera?
