How can I programmatically check what item is in the first, second, third, etc. inventory slot?

Hi!
Thank you for your plugin — it’s very convenient and well-designed!
However, I have one question I haven’t been able to solve.
How can I programmatically check what item is in the first, second, third, etc. inventory slot?
I’m creating a hotbar, and I want the player to use the first inventory slot when pressing key "1", the second when pressing key "2", and so on.

Thanks in advance!

Hi! I assume we are talking about basic inventories and the first item would be the "oldest" one, i.e. the one that was first added?
If so, than you could simply do something like this:

var all_items = inventory.get_items()
var first_item = all_items[0]
var second_item = all_items[1]
# etc.
var last_item = all_items[inventory.get_item_count() - 1]

Thank you for the quick reply!
And yes — I meant basic inventories.

However, what I’m trying to do is a bit different.
I need to access a specific slot (for example, the first or second one in the hotbar) — not just the first item that was added to the inventory.

In other words, if slot 0 is empty, I’d like to get null, and if it’s occupied, I’d like to get the item that’s currently in that slot.

Right now, inventory.get_items() returns all existing items, but without their corresponding slot indices, so I can’t tell which item belongs to which slot.

Here’s what I currently have:

extends CanvasLayer

@onready var inventory = $Control/HotbarInventory

func _ready():
    var all_items = inventory.get_items()
    
    if all_items.size() > 0:
        var first_item = all_items[0]
        print("First item:", first_item)
    else:
        print("Hotbar is empty or items are not loaded.")

Could you please tell me if there’s a way to access an ItemSlot directly (for example something like inventory.get_slot(0).get_item()), or another recommended approach to check which item is in a specific slot?

Hi!
I’ve found the solution.
To get the item in the first or second slot, I needed to use the get_item_at method in GridConstraint.
https://github.com/peter-kish/gloot/blob/master/docs/grid_constraint.md

Here’s the code:

extends CanvasLayer

@onready var grid = $Control/HotbarInventory/GridConstraint

func _ready():
	var first_item = grid.get_item_at(Vector2i(0, 0))
	var second_item = grid.get_item_at(Vector2i(1, 0))
	
	print(first_item)
	print(second_item)

Thank you so much for your help!
I can’t believe I missed that in the documentation earlier. 😊
