Godot：在页面间导航时出错；

我的代码有问题。

所有按钮都可以点击。但是当进入排行榜时。

然后按下退出按钮。

所有按钮都无法使用，并且什么也做不了。 以下是错误信息。

_parse_ext_resource: res://scenes/main_menu.tscn:16 - 解析错误：[ext_resource] 在 res://script/main_menu.gd 引用了不存在的资源

set_path：从路径 'res://scenes/main_menu.tscn' 加载另一个资源（可能包含循环资源）

下面是主菜单的代码：

class_name MainMenu
    
扩展控件
    
@onready var play_button = $MarginContainer/HBoxContainer/VBoxContainer/Play_Buttom as Button
@onready var exit_button = $MarginContainer/HBoxContainer/VBoxContainer/Exit_Button as Button
@onready var leaderboar_button = $MarginContainer/HBoxContainer/VBoxContainer/Leaderboar_Button as Button
@onready var start_level = preload("res://scenes/game.tscn")
@onready var start_mainmenu = preload("res://scenes/leader_board.tscn")
    
func _ready()：
    play_button.button_down.connect(on_play_pressed)
    exit_button.button_down.connect(on_exit_pressed)
    leaderboar_button.button_down.connect(on_leaderboard_pressed)

func on_play_pressed() -> void：
    get_tree().change_scene_to_packed(start_level)

func on_exit_pressed() -> void：
    get_tree().quit()

func on_leaderboard_pressed() -> void：
    get_tree().change_scene_to_packed(start_mainmenu)

下面是排行榜的代码：

 扩展控件
    
@onready var exit_button = $MarginContainer/HBoxContainer/VBoxContainer/Exit_Button
@onready var main_menu = preload("res://scenes/main_menu.tscn")
    
# 当节点首次进入场景树时调用。
func _ready(
    exit_button.button_down.connect(open_main_menu)

func open_main_menu()：
    get_tree().change_scene_to_packed(main_menu)

我已经尝试了所有方法，但我不知道如何解决这个问题。

The problem lies in your leaderboard scene script. You are attempting to load the main_menu.tscn scene in the open_main_menu function, but you have a typo in the resource path.

Here's the problematic line:

@onready var main_menu = preload("res://scenes/main_menu.tscn") 

The issue is that your Main Menu scene is saved as Main Menu.tscn (with capital letters), but you are referencing it as main_menu.tscn (lowercase).

Godot's file system is case-sensitive, so it treats these as two different files. Since it cannot find a file named main_menu.tscn , it throws the "Parse Error: [ext_resource]" you see.

Solution:

Correct the resource path in your leaderboard scene script to match the actual filename:

@onready var main_menu = preload("res://scenes/Main Menu.tscn") 

Make sure this path accurately reflects the location of your main menu scene file in your Godot project. Once you've made this change, save your script and try running the game again. The buttons should work correctly after returning from the leaderboard.
