(C#) For loop variable value not changing

I have this:

 for (int a = -1; a <= 1; a++) {
     for (int b = -1; b <= 1; b++) {

a and b don't change. I put a debug.log after that and it only says -1 for both a and b every time, although the loops does stop.

If you look at your console window, do you have the "Collapse" option enabled? That will sometimes combine multiple log messages into one message, which can be unintuitive if you're not expecting that.

Is it in the update function?

where did you put the Debug.Log()?

Something beyond the code you posted is going on. Put the following on an empty game object and run:

 using UnityEngine;
 using System.Collections;
 
 public class Example : $$anonymous$$onoBehaviour  {
     void Start() {
         for (int a = -1; a <= 1; a++) {
             for (int b = -1; b <= 1; b++) {
                 Debug.Log (a+", "+b);
             }
         }
     }
 }
