+# 开始菜单设计
+
+## 一、场景结构
+
+采用**单场景 + 子节点切换**方案，仅一个 `MainMenu.tscn`。
+
+```
+MainMenu.tscn
+├── BG (TextureRect)
+│   └── 背景图片
+├── Logo (TextureRect)
+│   └── 游戏 Logo
+├── ButtonGroup (VBoxContainer)
+│   ├── 新游戏按钮 → 显示 NewGamePanel
+│   ├── 读取存档按钮 → 显示 LoadGamePanel
+│   ├── 设置按钮 → 显示 SettingsPanel
+│   └── 退出按钮 → get_tree().quit()
+├── NewGamePanel (Panel, 默认隐藏)
+│   ├── 宗门名称输入框 (LineEdit)
+│   ├── 难度选择 (OptionButton)
+│   │   ├── 简单
+│   │   ├── 普通

+│   └── 返回按钮
+└── SettingsPanel (Panel, 默认隐藏)

+
+## 二、场景节点属性说明
+
+### MainMenu（根节点 — Control）
+
+| 属性 | 值 | 说明 |
+|------|----|------|
+| `anchors_preset` | 15（Full Rect） | 四角锚定父节点边界 |
+| `anchor_right` | 1.0 | 右边缘锚定到父节点右边界 |
+| `anchor_bottom` | 1.0 | 下边缘锚定到父节点下边界 |
+| `grow_horizontal` | 2 | 控件缩小时向右收缩 |
+| `grow_vertical` | 2 | 控件缩小时向下收缩 |
+| `size_flags_horizontal` | 3 | Fill + Expand，水平填充可用空间 |
+| `size_flags_vertical` | 3 | Fill + Expand，垂直填充可用空间 |
+
+### BG（TextureRect — 背景）
+
+| 属性 | 值 | 说明 |
+|------|----|------|
+| `anchors_preset` | 15（Full Rect） | 铺满父节点 |
+| `anchor_right` / `anchor_bottom` | 1.0 | 锚定右下边界 |
+| `stretch_mode` | 0（Scale） | 拉伸图片铺满，保持原始比例 |
+
+### Logo（TextureRect — 游戏 Logo）
+
+| 属性 | 值 | 说明 |
+|------|----|------|
+| `anchors_preset` | 1（Top Center） | 顶部居中锚点 |
+| `anchor_left` / `anchor_right` | 0.5 | 水平居中 |
+| `offset_left` | -200 | 左偏移，使宽度为 400 |
+| `offset_right` | 200 | 右偏移 |
+| `offset_top` | 60 | 距顶部 60px |
+| `offset_bottom` | 260 | 距顶部 260px（高 200） |
+| `grow_horizontal` | 2 | 向左收缩 |
+
+### ButtonGroup（VBoxContainer — 按钮组）
+
+| 属性 | 值 | 说明 |
+|------|----|------|
+| `anchors_preset` | 8（Center） | 居中锚定 |
+| `anchor_left / top / right / bottom` | 0.5 | 中心点对齐 |
+| `offset_left` | -100 | 向左扩展 100px（总宽 200） |
+| `offset_right` | 100 | 向右扩展 100px |
+| `offset_top` | -80 | 向上扩展 80px（总高 160） |
+| `offset_bottom` | 80 | 向下扩展 80px |
+| `grow_horizontal` | 2 | 向左收缩 |
+| `grow_vertical` | 2 | 向上收缩 |
+| `theme_override_constants/separation` | 16 | 按钮间距 16px |
+
+### Button（子按钮）
+
+| 属性 | 值 | 说明 |
+|------|----|------|
+| `custom_minimum_size` | Vector2(200, 48) | 按钮最小尺寸，宽 200 高 48 |
+| `text` | "新游戏" 等 | 按钮显示文字 |
+
+---
+
+## 三、面板切换逻辑
+
+所有面板放在同一场景内，通过 `visible` 属性切换。
+
+```gdscript
+func _on_new_game_pressed():
+    button_group.hide()
+    new_game_panel.show()
+
+func _on_back_pressed():
+    new_game_panel.hide()
+    button_group.show()
+```
+
+## 四、进入游戏流程
+
+新游戏确认后调用：
+
+```gdscript
+func _on_confirm_new_game():
+    var sect_name = $NewGamePanel/NameInput.text
+    var difficulty = $NewGamePanel/Difficulty.selected
+    # 初始化游戏数据
+    GameData.start_new_game(sect_name, difficulty)
+    get_tree().change_scene_to_file("res://src/main/MainGame.tscn")
+```
+
+## 五、注意事项
+
+- 面板切换使用 `show()` / `hide()`，不销毁节点，保留输入状态
+- 背景和 Logo 可加淡入动画（AnimationPlayer）
+- 存档列表数据来源：`ResourceSaver` 序列化的存档文件
