C3 Creating GameObject in script why give me an error ?
i started new project and created a c# script attached to Main Camera
using UnityEngine;
using System.Collections;
public class Main : MonoBehaviour
{
private GameObject[][] sphere;
void Awake()
{
for (int i = 0; i < 13; i++)
for (int j = 0; j < 11; j++)
{
sphere[i][j] = GameObject.CreatePrimitive(PrimitiveType.Sphere);
sphere[i][j].transform.position = new Vector3(2 * i, 2 * j, 0);
sphere[i][j].transform.localScale = new Vector3(1, 1, 1);
sphere[i][j].renderer.material.color = Color.red;
}
}
private void Start()
{
}
private void Update()
{
}
}
and when i tring if i can see spheres i got errors:
NullReferenceException: Object reference not set to an instance of an object Main.Awake () (at Assets/Main.cs:13)

You are declaring a jagged array (which I don't think is what you want). Plus you are not allocating space for the array. Try this:
public class NewBehaviourScript : MonoBehaviour
{
private GameObject[,] sphere = new GameObject[13,11];
void Awake()
{
for (int i = 0; i < 13; i++)
for (int j = 0; j < 11; j++)
{
sphere[i,j] = GameObject.CreatePrimitive(PrimitiveType.Sphere);
sphere[i,j].transform.position = new Vector3(2 * i, 2 * j, 0);
sphere[i,j].transform.localScale = new Vector3(1, 1, 1);
sphere[i,j].renderer.material.color = Color.red;
}
}
}
