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 = 16
enum { 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_size
var multiY = int(round(mouse_pos.y) / tile_size)
var numY = multiY * tile_size
var new_pos = Vector2(multiX, multiY)
var new_camp_fire = camp_fire.instance()
new_camp_fire.set_position(tile_size * new_pos)
grid[multiX][multiY] = OBSTACLE
get_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！！！
英文:
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!!!
