NullReferenceException when accessing variables in a 2D array in Unity
- by Syed
I have made a class including variables in Monodevelop which is:
public class GridInfo : MonoBehaviour {
public float initPosX;
public float initPosY;
public bool inUse;
public int f;
public int g;
public int h;
public GridInfo parent;
public int y,x;
}
Now I am using its class variable in another class, Map.cs which is:
public class Map : MonoBehaviour {
public static GridInfo[,] Tile = new GridInfo[17, 23];
void Start() {
Tile[0,0].initPosX = initPosX; //Line 49
}
}
I am not getting any error on runtime, but when I play in unity it is giving me error
NullReferenceException: Object reference not set to an instance of an object
Map.Start () (at Assets/Scripts/Map.cs:49)
I am not inserting this script in any gameobject, as Map.cs will make a GridInfo type array, I have also tried using variables using GetComponent, where is the problem ?
