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

Unity Engine
1

Hi! I’ve got this 2 erros (that aparentely means the same…)

and

on these piece of code:

		if (GUI.Button (Rect (0,30,200,30), button_Text1)) {
			button_Text1 = "No money no honey baby!";
			b_Play = false;
			GetComponent(SuperMarioCamera).enabled = true;
			GetComponent(Controller).enabled = true;
		}

I also have a

function Awake(){
	GetComponent(SuperMarioCamera).enabled = false;
	GetComponent(Controller).enabled = false;
}

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:

    if (GUI.Button (Rect (0,30,200,30), button_Text1)) {
         button_Text1 = "No money no honey baby!";
         b_Play = false;
         null.enabled = true;
         null.enabled = true;
      }

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:

var button_Text1 : String = "Play Game";
var button_Text2 : String = "Get Plug-in";
var button_Text3 : String = "CREDITS";
var b_Play = true;

function Awake(){
	GetComponent(SuperMarioCamera).enabled = false;
	GetComponent(Controller).enabled = false;
}

function OnGUI () {
	
	if(b_Play){
		// Make a group on the center of the screen
		GUI.BeginGroup (Rect (Screen.width / 2 - 100, Screen.height / 2 - 120, 300, 120));
		// All rectangles are now adjusted to the group. (0,0) is the topleft corner of the group.
	
		// We'll make a box so you can see where the group is on-screen.
		GUI.Box (Rect (0,0,200,200), "PROJECT");
		
		if (GUI.Button (Rect (0,30,200,30), button_Text1)) {
			button_Text1 = "No money no honey baby!";
			b_Play = false;
			GetComponent(SuperMarioCamera).enabled = true;
			GetComponent(Controller).enabled = true;
		}

		
		if (GUI.Button (Rect (0,60,200,30), button_Text2)) {
			button_Text2 = "UNITY3D.com";
		}
		
		if (GUI.Button (Rect (0,90,200,30), button_Text3)) {
			button_Text3 = "AQUIRIS";
		}

		// End the group we started above. This is very important to remember!
		GUI.EndGroup ();
	}
}

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?

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:

private var coolioComponent : CoolioComponent;
function Start ()
{
    coolioComponent = GetComponent(CoolioComponent);
    coolioComponent.enabled = false;
}

function Update ()
{
    // enable the component if the a key is held down
    coolioComponent.enabled = Input.GetKey("a"); 
}

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!!!
