(Closed)How to enable a disabled script?...

Hi! I've got this 2 erros (that aparentely means the same...)

and

on these piece of code:

Code (csharp):

1.  
2.         if (GUI.Button (Rect (0,30,200,30), button_Text1)) {
3.             button_Text1 = "No money no honey baby!";
4.             b_Play = false;
5.             GetComponent(SuperMarioCamera).enabled = true;
6.             GetComponent(Controller).enabled = true;
7.         }
8.  

I also have a

Code (csharp):

1.  
2. function Awake(){
3.     GetComponent(SuperMarioCamera).enabled = false;
4.     GetComponent(Controller).enabled = false;
5. }
6.  

in the same script, but i have no idea why is this going on...

Can anyone gimme a hand?

TXS!

 

Can we see the full script? You probably are doing something like calling GUI.BeginSomething(); without calling GUI.EndSomething();, or the script hits an exception and stops before reaching the EndSomething.

One thing that looks like it could cause an exception is that you are using GetComponent() on a component that I assume (from looking at your start function) is not enabled. GetComponent() does not find unenabled components. Therefore you might be doing:

Code (csharp):

1.  
2.     if (GUI.Button (Rect (0,30,200,30), button_Text1)) {
3.          button_Text1 = "No money no honey baby!";
4.          b_Play = false;
5.          null.enabled = true;
6.          null.enabled = true;
7.       }
8.  

You fix this by cashing a reference to each component in a private variable in Start, then setting enabled on those variables instead of with GetComponent().

 

Well my full code is:

Code (csharp):

1.  
2. var button_Text1 : String = "Play Game";
3. var button_Text2 : String = "Get Plug-in";
4. var button_Text3 : String = "CREDITS";
5. var b_Play = true;
6.  
7. function Awake(){
8.     GetComponent(SuperMarioCamera).enabled = false;
9.     GetComponent(Controller).enabled = false;
10. }
11.  
12. function OnGUI () {
13.    
14.     if(b_Play){
15.         // Make a group on the center of the screen
16.         GUI.BeginGroup (Rect (Screen.width / 2 - 100, Screen.height / 2 - 120, 300, 120));
17.         // All rectangles are now adjusted to the group. (0,0) is the topleft corner of the group.
18.    
19.         // We'll make a box so you can see where the group is on-screen.
20.         GUI.Box (Rect (0,0,200,200), "PROJECT");
21.        
22.         if (GUI.Button (Rect (0,30,200,30), button_Text1)) {
23.             button_Text1 = "No money no honey baby!";
24.             b_Play = false;
25.             GetComponent(SuperMarioCamera).enabled = true;
26.             GetComponent(Controller).enabled = true;
27.         }
28.  
29.        
30.         if (GUI.Button (Rect (0,60,200,30), button_Text2)) {
31.             button_Text2 = "UNITY3D.com";
32.         }
33.        
34.         if (GUI.Button (Rect (0,90,200,30), button_Text3)) {
35.             button_Text3 = "AQUIRIS";
36.         }
37.  
38.         // End the group we started above. This is very important to remember!
39.         GUI.EndGroup ();
40.     }
41. }
42.  

this was suposed to "turn On" the SuperMarioCamera and the Controller Scripts... If I change for null.enabled = true; as you said, how could I point those enables to the par of scripts?

TXS 4 Helping!!![/code]

 

I didn't say to use null.enabled = true;, I said that right now you are using that, because GetComponent(SuperMarioCamera) returns null if SuperMarioCamera is not enabled. And I think it isn't enabled.

Here is an example of what I was suggesting:

Code (csharp):

1.  
2.  
3. private var coolioComponent : CoolioComponent;
4. function Start ()
5. {
6.     coolioComponent = GetComponent(CoolioComponent);
7.     coolioComponent.enabled = false;
8. }
9.  
10. function Update ()
11. {
12.     // enable the component if the a key is held down
13.     coolioComponent.enabled = Input.GetKey("a");
14. }
15.  
16.  

 

Oww... Ok, I see! It was definitely null... The thing is that I'm trying to enable the disabled scripts... And I'm not having a good time with that.

By the way! Thank you VERY MUCH for the help so far!!!
