Godot 4 grid base item palcement
问题
我想用Godot 4制作一个开放式多人RPG游戏。问题是，我看过一个视频教程（这里），遇到了这个错误：
> Invalid get index '2' (on base: 'Array').
以下是我的代码：
extends Node2D@onready var camp_fire = preload("res://src/Scenes/camp_fire.tscn")var tile_size = 16enum { OBSTACLE, COLLECTABLE, RESOURCE }var grid_size = Vector2(160, 160)var grid = []func _ready():for x in range(grid_size.x):grid.append([])for y in range(grid_size.y):grid[x].append(null)var positions = []for i in range(50):var xcoor = (randi() % int(grid_size.x))var ycoor = (randi() % int(grid_size.y))var grid_pos = Vector2(xcoor, ycoor)if not grid_pos in positions:positions.append(grid_pos)func _input(event):if event.is_action_pressed("LeftClick"):var mouse_pos = get_global_mouse_position()var multiX = int(round(mouse_pos.x) / tile_size)var numX = multiX * tile_sizevar multiY = int(round(mouse_pos.y) / tile_size)var numY = multiY * tile_sizevar new_pos = Vector2(multiX, multiY)var new_camp_fire = camp_fire.instance()new_camp_fire.set_position(tile_size * new_pos)grid[multiX][multiY] = OBSTACLEget_tree().root.get_node("World").get_node("PlayerBuildings").add_child(new_camp_fire)

解决方案很简单。我将此脚本附加到我希望玩家能够放置物品的位置。我将此脚本放在了生成地图中物品的Node2D上！！！

The solution was simply. I had attach this script at the item which i want player to be able to place. I put this script at Node2D where i spawn the item in map!!!
