Atlas returning NullReference Exception

[kwelts]

I've made 2 atlases in the same manner and one works perfectly but the other keeps on getting NullReference.

Here's the code:

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class UIButtonTexture : MonoBehaviour {
5.        
6.         public UIAtlas ReferenceAtlas;
7.     public GameObject ReplacementAtlas;
8.         public string HomePanelTopBG;
9.     public string TopNavBar;
10.        
11.         bool AtlasSwitch;
12.         /*public UIButtonTexture(bool AtlasSwitch) {
13.         this.AtlasSwitch = AtlasSwitch;
14.         } */
15.        
16.         public enum Trigger {
17.                 OnClick,
18.         }
19.        
20.         public Trigger trigger = Trigger.OnClick;
21.        
22.        
23.         void Start() {
24.         AtlasSwitch = false;
25.         }
26.        
27.         public void OnClick() {
28.                 Debug.Log("---> Inside OnClick");
29.                 if (AtlasSwitch == false) {
30.                         AtlasSwitch = true;
31.                         Debug.Log("---> AtlasSwitch = "+AtlasSwitch);
32.                                 UpdateAtlas();
33.                         } else {
34.                         AtlasSwitch = false;
35.                         Debug.Log("---> AtlasSwitch = "+AtlasSwitch);
36.                                 UpdateAtlas();
37.                         }
38.         }
39.        
40.         public void UpdateAtlas() {
41.                 if (AtlasSwitch == true) {
42.                         Debug.Log("---> Inside UpdateAtlas [true side]");
43.                         ReplacementAtlas = Resources.Load("HomePanelTopBG") as GameObject;
44.             Debug.Log("---> Setting texture GO to 'Clicked'");
45.                 }
46.                 else {
47.                         Debug.Log("---> Inside UpdateAtlas [false side]");
48.                         ReplacementAtlas = Resources.Load("TopBlackBar") as GameObject;
49.             Debug.Log("---> Setting texture GO to 'Default'");
50.                 }
51.                
52.                 Debug.Log("---> Replacing Atlas. ReferenceAtlas = "+ ReferenceAtlas + " ReplacementAtlas = "+ReplacementAtlas);
53.                  ReferenceAtlas.replacement = ReplacementAtlas.GetComponent<UIAtlas>();
54.                 Debug.Log("Atlas Replaced");
55.         } // end UpdateAtlas()
56. }

Error occurs when it won't actually load the resource "TopBlackBar", and halts at " ReferenceAtlas.replacement = ReplacementAtlas.GetComponent<UIAtlas>();" with the error.

Both atlases are located in the same folder and are named properly. Any idea what is happening that i'm unaware of?
Thanks for your time.

All I can suggest is look closely at what's different between them and to make sure you spelled the name correctly.

[kwelts]

ok thanks for the response (at least i have something to focus on).

[kwelts]

code is the same. it changes once but not back. i've gone through everything i can so im just going to post every little relevant part of my project and you can see if I missed something crucial.

[ArenMook]

I don't see anything wrong.

[kwelts]

oh noes!

Ran into this problem yesterday.  Try renaming the actual atlas prefab to something that doesn't match the material and texture.  By default, NGUI creates all 3 with the same name, but this can confuse the Resource Load.
