Losing variable reference somewhere?

Unity Engine
1

Hola a todos,

I have an Inventory class, that represents my inventory (duh :p) with a List (another class)
My Player Controller Script has an Inventory. Then, I have a WorldController class that uses the Player reference to reach his inventory, and update several panel, showing these items.

Now, the WorldController script knows my inventory has some items (itemList.Count > 0) but when accessing the List childs, they’re all null.
Maybe i’m losing the reference someewhere?

I leave you the important code.

Player Controller

void FixedUpdate(){
        if (Input.GetKey (KeyCode.F)) {
           //focus keeps the reference to the item i'm picking
            if (focus != null) {
                myInventory.PickupItem (focus);
                Debug.Log (focus);
                Destroy (focus.gameObject);
                focus = null;
            }
      }
}

Inventory

public class Inventory {
   
    private List<Item> itemList;

    public Inventory(){
        itemList = new List<Item>();
    }

        public void PickupItem(Item item){
        itemList.Add (item);
    }

    public List<Item> GetItems(){
        return itemList;
    }
}

WorldController

public class WorldController : MonoBehaviour {

    public GameObject inventoryPanel;
    public GameObject player;

    private Inventory inventory;

    public void Start(){
        inventory = player.GetComponent<PlayerController> ().GetInventory();
    }

    public void Update(){
        UpdatePanel ();
    }

    public void UpdatePanel(){
        int i = 0;
        for (i=0; i < inventoryPanel.transform.childCount; i++) {
            Transform panel = inventoryPanel.transform.GetChild (i);
            Item anItem = (i < inventory.GetItems().Count) ? 
                                inventory.GetItems()[i] : null;
            Debug.Log (i < inventory.GetItems ().Count);
             //This goes true when something's picked
            Debug.Log("Total :" + inventory.GetItems().Count + 
                    " - - " + (anItem!=null?anItem.name:"Nada")); 
            //Having some items keep logging "Nada"
            panel.FindChild ("Item #").GetComponent<Text> ().text = anItem != null?anItem.Name:"";
        }
    }
}

Thank you all, I hope my english is ok.

Ok, so, playing a bit with the variables, I found that when I call ‘Destroy’ on the focus variable, it destroys everything even the Item reference despite I’m keeping it in a Collection.

Resolved by SetActive(false) the gameobject.
