Get first gameobject in a list and cycle through on keypress
Hi. I am trying to make an inventory in which the player can cycle through the inventory with a keypress. Right now, the current item that has been picked up by the player would be shown on the text. However, I want the player to be able to cycle through the previous items that he have picked up.
public KeyCode PickupButton;
public Text Players_Inventory;
public List<GameObject> Items = new List<GameObject>();
void Update ()
{
Input.GetKeyDown(PickupButton);
}
void OnTriggerStay(Collider other)
{
Debug.Log("Collision");
if (other.gameObject.tag == "Player" && Input.GetKeyDown(PickupButton))
{
Debug.Log("Button is pressed");
Items.Add(gameObject);
Destroy(gameObject);
Debug.Log("GameObject is destroyed");
Players_Inventory.text = "Items: " + (gameObject);
}
}
How do I cycle through a list of gameobject?
On a side note, when you inspect the Items list, are all the elements null/empty?
The object is added to the list but it is showing missing gameobject. So while the element of the list is increasing, it is showing as empty gameobject. Currently. I am using gameobject.setActive(false) as a alternative so I am still able to access the list.
What is this script attached to? You add gameObject to Items, but gameObject refers to the game object to which the script is attached. I think you meant to use other.gameObject.
$$anonymous$$oreover, you immediately Destroy() gameObject, so of course you will get "missing game object" - it has just been destroyed.
If this is a script for an inventory, then you want to add a data object to the list of items based on what kind of object the player picks up. Then you can destroy the item, which you can get from other.gameObject. But possibly you don't need to do that, it all depends on your setup.
Hi, I don’t understand how your script works... is this script attached to your items to pick up? And why are you destroying your object BEFORE you do: Players_Inventory... If you destroy the object the following lines will never be executed.
Anyway if you want to cycle throught an object list you can do something like this:
public List<GameObject> Items = new List<GameObject>();
public GameObject CurrentItemObject;
public int CurrentItemInt;
void Update()
{
if (Input.GetKeyDown(“right”)
{
CurrentItemInt += 1;
}
if (Input.GetKeyDown(“left”)
{
CurrentItemInt -= 1;
}
if (CurrentItemInt >= Items.Count)
{
CurrentItemInt = 0;
}
if (CurrentItemInt < 0)
{
CurrentItemInt = Items.Count - 1;
}
CurrentItemObject = Items[CurrentItemInt];
}
Yes. The script is attached to my item. Originally, it is attached to the player but it is not very smart of me to do so. I managed to get it to work. But I can't seems to change the displayed text according to the current Item.
CurrentItemobject = Items[0];
CurrentItemobject = Items[CurrentItem];
This is my current script. In the inspector, I can see that I am able to swap between the items that I've added to the list previously. However, the text that is displayed remains the same.
Change your Text script so:
Players_Inventory.text = "Items: " + CurrentItemObject;
If it doesn’t work send the complete script that you have now so I understand better.
