Calling a variable from another script?

Setting up a variable in my gamecontroller
an int called LevelNumber

For a test i want it to print to log when it collides with a trigger in another script, iv tried doing this but coming up with a few errors, i feel like im on the right track but cant get it working please help
GameControllerScript:

Code (csharp):

1.  
2. public int LevelNumber = 0;
3. void Start () {
4.         LevelNumber = 1;
5.     }
6.  

The test trigger script:

Code (csharp):

1.  
2. void OnTriggerEnter( Collider other )
3.     {
4.         GameObject go = other.gameObject;
5.         GameControllerScript.GetComponent (GameControllerScript.LevelNumber);
6.         Debug.Log (GameControllerScript.LevelNumber);
7. }
8.  

 

Plz use Code Tags Like this

Code (csharp):

1.  
2. Public John john;
3.  

 

When u type u hv a option to insert code just past it there it seems like a page with lanes

Take away the .

 

Yeah thanks got it sorted now as you can see,
anyone help with the issue?

 

How i do it is have GameController be a parent or child of test collider
Then do this

Code (csharp):

1.  
2. public GameController game;
3.  
4. void Update(){
5.     Debug.Log(game.LevelNumber);
6. }
7.  

 

Luke, try this...

Code (CSharp):

1. void OnTriggerEnter(Collider other)
2. {
3. GameObject go = other.gameObject;
4. int level = go.GetComponent<GameControllerScript>().LevelNumber;
5. Debug.Log (level);
6. }

 

I think Luke needs to read a bit on Object Oriented Programming, as well as basic C# and programming lessons.

Do not take this the wrong way, I'm not saying that you are stupid, or anything like this.
What I mean is that this is the sort of mistakes that anyone that does not understand the language could do, and even if learning on it takes time, it give you the opportunity to do these things and read the error messages in order not to be stuck waiting from an answer from other people, that will always seem to take a long time, because you are stuck on it at the time.

I do pass as a very mean person picking on others, when I'm writing these things...

 

Hey there thanks for the helpful idea but it comes up with an error that says

Code (csharp):

1.  
2.  
3. NullReferenceException: Object reference not set to an instance of an object
4. Key.OnTriggerEnter (UnityEngine.Collider other) (at Assets/Key.cs:20)
5.  
6.  

 

I understand with what your saying and completely agree i just need abit of help right now for a push

 

Also tried this but comes up with the same error as what i got for grizzly

 

The other object must have your script attached. You can handle this like so...

Code (CSharp):

1.  
2. GameObject go = other.gameObject;
3. GameControllerScript script = go.GetComponent<GameControllerScript>();
4.  
5. if (script != null) {
6.    Debug.Log (script.LevelNumber);
7. } else {
8.    Debug.Log ("Script not found!");
9. }
10.  
11.  

 

Hey getting no errors now but its coming up with the "Script not found!"

 

"Script not found!" will appear when you enter a trigger that does not contain your script. That message was included for debugging only and can(should) be removed when you're done.

Since you're setting LevelNumber to 1 in Start(), make sure your scripts are enabled (ticked on the component) and Start() is correctly being called.

 

When you say the trigger doesnt contain my script, should i add the GameController script to the key object then?
i already have the gamecontroller parenting all other objects so i thought that would be alright

 

All objects requiring this functionality should have your script attached, yes.

 

So i should be attaching the gamecontroller script to all relevant objects not just an empty object,
or adding the key script to the gamecontroller?

 

Luke,

TestTriggerScript - Should be attached to your "key" object.
GameControllerScript - Should be attached to all "relevant" objects that trigger your "key" object.

To get a better grasp of MonoBehaviours/Components, I do recommend having a good read through the docs...
