Godot 4.5.1
So I’m coding an inventory system for my game, but when I run the below script, it teleports ALL the items to the slot node. How do I only teleport the nearest?
Item Code:
extends Node2D
var mouse_is_in = 0
func _ready() -> void:
pass
func _process(_delta) -> void:
if mouse_is_in == 1:
scale = Vector2(0.22, 0.22)
if Input.is_action_pressed("Click"):
self.global_position = get_global_mouse_position()
if mouse_is_in == 0:
scale = Vector2(0.2, 0.2)
func _on_area_2d_body_entered(body) -> void:
print("Entered")
if Input.is_action_pressed("Click"):
self.global_position = get_global_mouse_position()
func _on_area_2d_mouse_entered() -> void:
mouse_is_in += 1
func _on_area_2d_mouse_exited() -> void:
mouse_is_in = 0
And this is the slot code:
extends Area2D
var is_in = 0
@onready var Item = $“../Item”
func _on_area_entered(area: Area2D) → void:
is_in += 1
func _on_area_exited(area: Area2D) → void:
is_in = 0
func _process(_body) → void:
if is_in == 1:
if !Input.is_action_pressed(“Click”):
print(“if works”)
is_in = 0
Item.global_position = get_global_position()
All code is written by me, and I’m pretty new, so it may not be terribly efficient.
What happened to the indentations in your second code block?
I’m not seeing a distance comparison in your code. How are you determining “nearest”?
At first glance, these two lines look like your problem. When you capitalize a variable name, Godot assumes it’s a class name. I don’t see a class_name in your item script, but still, I’d suggest this:
class_name Item extends Node2D
var mouse_is_in = 0
func _process(_delta) -> void:
if mouse_is_in == 1:
scale = Vector2(0.22, 0.22)
if Input.is_action_pressed("Click"):
self.global_position = get_global_mouse_position()
if mouse_is_in == 0:
scale = Vector2(0.2, 0.2)
func _on_area_2d_body_entered(body) -> void:
print("Entered")
if Input.is_action_pressed("Click"):
global_position = get_global_mouse_position()
func _on_area_2d_mouse_entered() -> void:
mouse_is_in += 1
func _on_area_2d_mouse_exited() -> void:
mouse_is_in = 0
Then…
@onready var item: Item = $“../Item”
# Other code
item.global_position = get_global_position()
This will prevent naming conflicts,
I think just an error when I copied and pasted, but they’re in the actual code, don’t worry.
I haven’t done that yet, as I’m not quite sure the best way to go about it, thus the post.
I’m not worried about your code. I can’t really read yours without them. If there’s an indentation issue, I cannot tell.
Where do I put these in my code? When I tried to put them at the top, it gave the error
Error at (4, 27): Invalid character ““” (U+201C).
Assuming “nearest” is based on pixel distance to the slot, I would approach the problem like this:
Create an array that holds the inventory items which are not stored
Search each member of the array to find the closest one
Move the inventory item into the slot
Remove the inventory item from the array
Ah, okay. Here are screenshots
Okay, thanks. New problem: I have NO CLUE what an array even is, and certainly not how to use it.
Don’t worry about not knowing what an array is. All of us were there at some point.

Thanks! I’ll read this after work, but my lunch break’s almost over.

They replace the lines I quoted. Lines 3 and 18 from your screen shot. The problem with a screen shot of your code is that I cannot copy and paste it and edit it. I’d have to re-type it all, and I’m not doing that. Still, that should help.
This is where I put everything, but it gives me the error
Trying to assign value of type ‘New_Item.gd’ to a variable of type ‘Inven_slot.gd’.
On what line does it give that error?
To my understanding it’s happening at 1:31
Well line 1 clearly doesn’t have 31 characters in it. Can you copy and paste the exact error?
I think it’s this:
E 0:00:00:859 Item.@implicit_ready: Trying to assign value of type ‘New_Item.gd’ to a variable of type ‘Inven_slot.gd’.Inven_slot.gd:3 @ Item.@implicit_ready() Inven_slot.gd:3 @ @implicit_ready()
