Question
Hi there - I think I made a mistake somewhere. I am trying to follow a video by DevWorm to write code for a game I am trying to develop. The code is for an inventory system that updates the UI slots as you collect an item.
I keep getting the error "Invalid access to key property or texture on a base object of type ‘Nil’.
I have rewatched the videos loads of times and the code is similar / the same with my own variables in places. I am feeling a little confused. Please help!
It tells me the error are in these two scripts:
extends Panel
@onready var item_visual: Sprite2D = $CenterContainer/Panel/item_display
@onready var amount_text: Label = $CenterContainer/Panel/Label
func update(slot: InvSlot):
if !slot:
item_visual.visible = false
amount_text.visible = false
else:
item_visual.visible = true
item_visual.texture = slot.item.texture
amount_text.visible = true
amount_text.text = str(slot.amount)
^^^ Line 12
extends Control
@onready var inv: Inv = preload("res://inventory/playerinv.tres")
@onready var slots: Array = $NinePatchRect/GridContainer.get_children()
var is_open = false
func _ready():
inv.update.connect(update_slots)
update_slots()
close()
func update_slots():
for i in range(min(inv.slots.size(), slots.size())):
slots[i].update(inv.slots[i])
func _process(delta):
if Input.is_action_just_pressed("e"):
if is_open:
close()
else:
open()
func open():
visible = true
is_open = true
func close():
visible = false
is_open = false
^^^ Lines 10 and 16
Any help would be beautiful, I am trying to get basic functions in the game so that I can start adding the actual content and story / mechanics.
Thanks!
