Question
Hello everyone! I am trying to make a fishtank game with multiple scenes. I have a scene for “maintank”, one for “inventory” and one for “iteminfo”. The idea is that you buy tanks from the shop, they add to your inventory (via a dictionary in a script called Global), and then you can place those tanks into your room (maintank scene) via a use button that pops up when you click on your inventory and then “use” the desired tank (iteminfo). In the game you start of with a plastic bag, and then you can update your tank → therefore in the maintank you start off with a baggy sprite2d that would hopefully change texture to the icon of the tank you “use” and everything in my script indicates that the texture should change… but it isn’t.
I have followed many tutorials and have asked AI, read forums etc - overall I have tried very hard to fix this issue on my own but as a beginner I am now totally lost. Below are all the relevant scripts that I believe are responsible for this failure to change the texture.
As for the scene tree. Main tank is the ‘parent’ with Placeditem (the sprite2d that I want to change) as a child and Inventory attached to that. Inventory is then a parent of “iteminfo” and “inventorygrid”. Inventory has no script attached to itself.
Let me know if you need any other info from me!! Really appreciate any help 
Main tank script
extends Control
@onready var placeditem: Sprite2D = %Placeditem
var ItemName = ""
var ItemDes = ""
var ItemCost = 0
var ItemCount = 0
var CurrItem = 0
var select = 0
# Called when the node enters the scene tree for the first time.
func _ready() -> void:
$inventory.hide()
Global.item_changed_globally.connect(_thissomeshit)
func _thissomeshit(item_index: int) -> void:
var item_data = Global.inventory[item_index]
print("watch dis SPACE")
print(item_data["icon"])
%Placeditem.texture = item_data.icon
%Placeditem.scale = Vector2(1, 1) # Ensure it's not tiny
%Placeditem.z_index = 100 # Ensure it's on top
%Placeditem.show() # Ensure it's not hidden
%Placeditem.position = Vector2(500, 300)
print("Placed: ", item_data.Name)
print("Texture should now be: ", item_data["Name"])
func _on_button_pressed() -> void:
get_tree().change_scene_to_file("res://scenes/leave_house.tscn")
func _on_add_pressed() -> void:
hide()
$inventory.show()
Global script:
extends Node
signal item_changed_globally(new_index)
var gold = 1000
var tanks = {
0: {

"Des": "Start here brokie!",

var feesh = {

}
Iteminfo script:
extends CanvasLayer
signal item_changed_globally(new_index)
var ItemName = ""
var ItemDes = ""
var ItemCost = 0
var ItemCount = 0
var CurrItem = 0
var select = 0
var current_selected_index : int = 0
func _process(_delta):
pass
# Called when the node enters the scene tree for the first time.
func _ready() -> void:
pass
# Called every frame. 'delta' is the elapsed time since the previous frame.
func updateInfo():
get_node("title").text = ItemName
get_node("des").text = ItemDes + "\nCost" + str(ItemCost)
current_selected_index = CurrItem
func _on_use_pressed() -> void:
for i in Global.inventory:
if Global.inventory[i]["Name"] == ItemName:
print("Emitting Index: ", i)
Global.item_changed_globally.emit(i)
ItemCount -=1
if ItemCount == 0:
var tempDic = {}
for x in Global.inventory:
if x > i:
tempDic[x-1] = Global.inventory[x]
elif x < i:
tempDic[x] = Global.inventory[x]
Global.inventory.clear()
Global.inventory = tempDic
_on_close_pressed()
else:
Global.inventory[i]["Count"] -=1
get_node("../inventorycontainer").fillInventorySlots()
func _on_close_pressed() -> void:
get_tree().change_scene_to_file("res://scenes/inventory.tscn")
And finally Inventorygrid container script:
extends GridContainer
@onready var item = preload("res://scenes/slot.tscn")
var invSize = 24
func _ready():
#load slots in
for i in invSize:
var ItemTemp = item.instantiate()
add_child(ItemTemp)
fillInventorySlots()
func fillInventorySlots():
for i in invSize:
get_child(i).ItemName = ""
get_child(i).ItemDes = ""
get_child(i).ItemCost = 0
get_child(i).ItemCount = 0
get_child(i).hasItem = false
#fills in inventory == slots
for i in Global.inventory:
get_child(i).ItemName = Global.inventory[i]["Name"]
get_child(i).ItemDes = Global.inventory[i]["Des"]
get_child(i).ItemCost = Global.inventory[i]["Cost"]
get_child(i).ItemCount = Global.inventory[i]["Count"]
get_child(i).get_node("count").text = str(Global.inventory[i]["Count"])
get_child(i).get_node("icon").texture = Global.inventory[i]["icon"]
get_child(i).hasItem = true
```
