Close to fixing my code, but its trowing erros at the connecting script between the slot and invnetory

Godot Version

Godot v4.2.1.stable


the code as of this moment is

extends Node

const Guard = preload("res://assets/characters/guard/")
const Guardbullet = preload("res://assets/items/guard_bullet/guard.tscn")
const Explorer = preload("res://assets/characters/explorer/")

var ItemClass = preload("res://assets/inventory/gun.tscn")
var Item = null
var player: Explorer

@onready var inventory_label = $Label

func _ready():
	player = get_node("res://assets/characters/explorer/")
	if player:
		player.connect("inventory_changed", self, "_on_inventory_changed")

func _input(event):
	if event is InputEventKey and event.pressed:
		if event.keycode == KEY_P:
			Item = ItemClass.instance()
		if event.keycode == KEY_K:
			player.change_inventory("gun", -1)

func _process(delta):

func _on_inventory_changed():
	var inventory = player.inventory
	var inventory_text = ""
	for item_name in inventory:
		inventory_text += item_name + ": " + str(inventory[item_name]) + "\n"
		inventory_label.text = inventory_text

inventory script in the explorer file is

signal inventory_changed()

var inventory = {
	"empty_hands" : 1,
	"gun" : 0,
	"sword" : 0,
	"medkit" : 0

and also to know which one specifically is selected at the time in the / script.

var weapons_list = ["gun", "sword","medkit"]
var active_weapon = "empty_hands"
var changing_weapon = false
var weapon_change_timer =
func on_weapon_changed():
	changing_weapon = false

i don’t even know if the
player.change_inventory("gun", -1)
will even work. i need a way for it to read specifically gun from the script, or maybe make it do all of them but then i need to load everything into a single script and i don’t know how to do that. this is my 4th iteration of the script and i still do not know how to make it work, i need to first figure out to hit P and it adds the gun to my inventory and with K to remove it, and also understand that the explorer has pickup also physically , cause the keybind is a placeholder for debug testing

You have to pass the player node’s node path for get_node, not the file path of the script.
You can drag&drop the player node into the script to get it’s path.

After that try connecting the signal like this:
