Need help implementing level counter

I am extremely new to Unity and would love some help getting a level counter put into my game. Basically, I am only trying to display the level the player is on in the game. This is what I have written so far, and though the debug.logs are triggering, the text on the game is not changing (and yes I have assigned the text variable in the inspector). UPDATE: the levelUpdate method is triggering every time the scene changes.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using UnityEngine.SceneManagement;
4.  
5. //public Text level = SceneManager.GetActiveScene().buildIndex.ToString("0");
6.  
7.  
8. public class levelCounter : MonoBehaviour {
9.  
10.     //public int levelCount;
11.     public Text levelText;
12.  
13.     private void Start()
14.     {
15.         //levelCount = SceneManager.GetActiveScene().buildIndex;
16.     }
17.     // Update is called once per frame
18.     public void levelUpdate ()
19.     {
20.         //levelCount++;
21.         Debug.Log("Triggered");
22.         int buildIndex = SceneManager.GetActiveScene().buildIndex;
23.         levelText.text = buildIndex.ToString("0");
24.         Debug.Log(SceneManager.GetActiveScene().buildIndex);
25.     }
26. }

Thanks for any help you are able to provide!

 

I don't see how the following would result in anything but a string of "0", though I'm rusty on my custom string formatting.

Code (csharp):

1. levelText.text = buildIndex.ToString("0");

Just try without the custom formatting first, and work from there.

Code (csharp):

1. levelText.text = buildIndex.ToString();

 

Thanks for the quick reply! I figured it out in the past twenty minutes, I declared the integer buildIndex in the start function, and after that, it just started to work! Full working code:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using UnityEngine.SceneManagement;
4.  
5. //public Text level = SceneManager.GetActiveScene().buildIndex.ToString("0");
6.  
7.  
8. public class levelCounter : MonoBehaviour {
9.  
10.     public Text levelText;
11.     public int buildIndex;
12.  
13.  
14.     private void Start()
15.     {
16.         buildIndex = SceneManager.GetActiveScene().buildIndex;
17.         Debug.Log(SceneManager.GetActiveScene().buildIndex + 1);
18.         levelText.text = "Level: " + buildIndex.ToString("0");
19.     }
20.    
21.     public void levelUpdate ()
22.     {
23.         Debug.Log("Triggered");
24.         levelText.text = "Level: " + buildIndex.ToString("0");
25.         Debug.Log(SceneManager.GetActiveScene().buildIndex+1);
26.     }
27. }
28.  

 

It sounds like your going to use this variable through out your game. Just a suggestion, have you considered storing it in Player Prefs or something global so you can access it across the scenes?

 

I attached it to an object that is a child of my UI canvas that is a prefab used throughout the game. Is that the same thing?
