Array index is out of range when initializing multidimensional arrays

Questions & Answers
1

I am getting an error immediately when I start:
IndexOutOfRangeException: Array index is out of range.

I understand you don’t need to initialize to 0. It gives same error if I try to initialize to another int. Can anybody tell me what I am doing wrong?

 using UnityEngine;
 
 using System.Collections;    
 
 
 public class simpleMultiDarrays : MonoBehaviour {
     int[,] xyb_count_array = new int[6, 6];
     
     int[,] xyr_count_array = new int[6, 6];
     
 
     void Start()
     {
         int inity = 0;
         for (inity = 0; inity < 6; inity++)
         {
 
             int initx = 0;             
             for (initx = 0; initx < 6; initx++)
             {
 
                 xyb_count_array[initx, inity] = 0;
 
                 xyr_count_array[initx, inity] = 0;
                                 
             }

             
         }
     }
 }

Replace your code with this, it will tell you were your error is

using UnityEngine;
using System.Collections;    


public class simpleMultiDarrays : MonoBehaviour
{
    int[,] xyb_count_array = new int[6, 6];

    int[,] xyr_count_array = new int[6, 6];


    void Start()
    {
        if ((xyb_count_array != null) && (xyr_count_array != null))
        {
            Debug.Log("xyb_count_array.Length = " + xyb_count_array.Length + ", xyr_count_array.Length = " + xyr_count_array.Length);
            for (int inity = 0; inity < 6; inity++)
            {
                for (int initx = 0; initx < 6; initx++)
                {
                    string error = "inity = " + inity + ", initx = " + initx + ", ";
                    if (xyb_count_array[initx, inity] == null)
                        error += "xyb_count_array[" + initx + ", " + inity "] = null, ";
                    else
                        xyb_count_array[initx, inity] = 0;

                    if (xyr_count_array[initx, inity] == null)
                        error += "xyr_count_array[" + initx + ", " + inity "] = null, ";
                    else
                        xyr_count_array[initx, inity] = 0;
                    Debug.Log(error);
                }
            }
        }
        else
        {
            string error = "";
            if (xyb_count_array == null)
                error = "xyb_count_array == null, ";
            if (xyr_count_array != null)
                error += "xyr_count_array == null";
            Debug.Log(error);
        }
    }
}

Thank you for your answer.
I found error in my syntax. My code in unity varied very slightly from the sample I posted.

I put the following debug line in my code and was able to find where it was producing the error.

              xyb_count_array[initx, inity] = 0;

              xyr_count_array[initx, inity] = 0;
              Debug.Log("Setting position X" + initx + " Y" + inity + " to 0");
          }
