Int is not interpreted as int

Hey

I am trying to get an int into an if condition. But I get this null pointer error all the time:

NullReferenceException: Object reference not set to an instance of an object
InventoryTutorial.addItemSSS (System.Int32 x, System.Int32 y, Item item) (at Assets/Inventory/InventoryTutorial.cs:181)
InventoryTutorial.detectMouseAction () (at Assets/Inventory/InventoryTutorial.cs:261)
InventoryTutorial.detectGUIAction () (at Assets/Inventory/InventoryTutorial.cs:196)
InventoryTutorial.OnGUI () (at Assets/Inventory/InventoryTutorial.cs:107)

The code snippet the error comes from is the following:

Code (CSharp):

1.  
2.  
3.     void addItem(int x, int y, Item item)
4.     {
5.         for (int sX = 0; sX < item.width; sX++)
6.         {
7.             for (int sY = 0; sY < item.height; sY++)
8.             {
9.                 if (slots[x, y].occupied)
10.                 {
11.                     // Debug.Log("breaks " + x + ", " + y);
12.  
13.                     return;
14.                 }
15.             }
16.         }
17.  
18.         if (x + item.width > slotWidthSize)
19.         {
20.             Debug.Log("Item out of X bounds!");
21.             return;
22.         }
23.  
24.         else if (y + item.height > slotWidthSize)
25.         {
26.             Debug.Log("Item out of Y bounds!");
27.             return;
28.         }
29.  
30.         item.x = x;
31.         item.y = y;
32.  
33.         // Debug.Log("Coordinates are " + x + ", " + y);
34.  
35.         items.Add(item);
36.  
37.         for (int sX = x; sX < item.width + x; sX++)
38.         {
39.             for (int sY = y; sY < item.height + y; sY++)
40.             {
41.                 slots[sX, sY].occupied = true;
42.             }
43.         }
44.     }
45.  
46.  
47.                       if (secondSelected.x != selected.x || secondSelected.y != selected.y)
48.                         {
49.                             // dragItem();
50.                             Debug.Log("secondSelected.x in int is: " + (int)secondSelected.x + ", and secondSelected.y in int is: " + (int)secondSelected.y);
51.                             addItem((int)secondSelected.x, (int)secondSelected.y, temp);
52.  
53.                         }
54.  
55.  
56.  

Why is the int not interpreted as such and gives me this null pointer exeption?

 

On line 24, you use the width variable instead of the height. Perhaps this is not the reason, but there is such a mistake.

 

Wow just skipped that point. now I see it. it fixed the problem. Thank you, GladStudio.
