NullReferenceException when changing values via script - But still works!

Hi

I am in love with the new UI! Everything is going well but I have found an odd error in the script at the bottom of this post.

The first line in the Start function generates this error:
NullReferenceException: Object reference not set to an instance of an object
uiStats.Start () (at Assets/Scripts/UI/uiStats.cs:12)

However both the slider and the text get updated fine.

If I comment out that line, the next line produces the same error and so on. It's been a long day so maybe I am missing something

Here is the code:

Code (CSharp):

1. using System.Collections;
2. using UnityEngine;
3. using UnityEngine.UI;
4.  
5. public class uiStats : MonoBehaviour
6. {
7.     public Text shieldTextComponent;                              
8.     public Slider shieldBarDisplay;
9.  
10.     // Use this for initialization
11.     void Start () {
12.         shieldBarDisplay.minValue = 0;
13.         shieldBarDisplay.maxValue = 100;
14.         shieldBarDisplay.value = 50;
15.         shieldTextComponent.text = "Hello world!";
16.     }
17. }

 

Put a

Code (csharp):

1. Debug.Log(gameObject.name);

before the line that causes the error. I bet you a dollar you have that script on another object as well as the one you intended.

 

I had looked for that but totally missed it last night, found it straight away this morning, and I should have used debug like that and stopped coding earlier last night

Thanks StarManta *gives $1*.

 

finally i can retire and quit this life of crime
