[SOLVED] Multigrid Inventory

I've been trying to create a multigrid inventory. So far, it works if I try to insert a 1x1 item. However, I'm trying to figure the syntax in order to implement my logic. I know I need to check if the slots on the X axis and the Y axis are free, but I'm having trouble doing that. All my slots have a Slot.cs script inside them, with proper initialization, so, all of them have the correct values inside.

Edit: I'm using Grid Layout Group on my panel and setting the constraintCount to match the columns.

Inventory.cs

Code (CSharp):

1. void Start () {
2.  
3.         slotPanel.GetComponent<GridLayoutGroup> ().constraintCount = colunas;
4.         if (maxSize % colunas == 0) {
5.             linhas = maxSize / colunas;
6.         } else {
7.             linhas = (maxSize / colunas) + 1;
8.         }
9.  
10.         for (int x = 0; x < linhas; x++) {
11.             for (int y = 0; y < colunas; y++) {
12.                 var slots = Instantiate (slotPrefab);
13.                 slots.transform.SetParent (slotPanel.transform);
14.                 slots.GetComponent<Slot> ().x = x;
15.                 slots.GetComponent<Slot> ().y = y;
16.                 slots.GetComponent<Slot> ().isEmpty = true;
17.                 slotList.Add (slots);
18.                 slots.name = x.ToString () + " , " + y.ToString ();
19.                 if (slotList.Count == maxSize) break;
20.      
21.             }
22.         }
23.          
24.     }
25.  
26. ...
27. public bool hasSpace(GameObject item){
28.  
29.  
30.         var itemReference = item.GetComponent<Item> ();
31.         print ("ItemVolume: " + itemReference.volume);
32.         for (int i = 0; i < slotList.Count; i++) {
33.             int volume = 0;
34.             Slot slot = slotList [i].GetComponent<Slot> ();
35.             if (slot.isEmpty) {
36.                 if (itemReference.x == 1 && itemReference.y == 1) {
37.                     AddItem (item, slot);
38.                     return true;
39.                 } else {
40.                  
41.  
42.  
43.  
44.
