+# Maya 工具架按钮命令
+
+所有工具的标准启动命令，**不需要使用绝对路径**。
+
+## 📋 前提条件
+
+确保 `animation_tools` 在 Maya 的 Python 路径中。通常通过以下方式之一：
+
+1. **userSetup.py** (推荐)
+   ```python
+   import sys
+   import os
+   scripts_path = r'h:\Workspace\Raw\Tools\Plugins\Maya\2023\scripts'
+   if scripts_path not in sys.path:
+       sys.path.insert(0, scripts_path)
+   ```
+
+2. **Maya.env**
+   ```
+   PYTHONPATH=h:\Workspace\Raw\Tools\Plugins\Maya\2023\scripts
+   ```
+
+## 🔧 工具架按钮命令
+
+### 1. Studio Library
+
+**Python 命令：**
+```python
+import animation_tools.studiolibrary as studiolib
+studiolib.show()
+```
+
+**MEL 命令：**
+```mel
+python("import animation_tools.studiolibrary as studiolib; studiolib.show()");
+```
+
+---
+
+### 2. DreamWall Picker
+
+**Python 命令：**
+```python
+import animation_tools.dwpicker as dwpicker
+dwpicker.show()
+```
+
+**MEL 命令：**
+```mel
+python("import animation_tools.dwpicker as dwpicker; dwpicker.show()");
+```
+
+**切换显示/隐藏：**
+```python
+import animation_tools.dwpicker as dwpicker
+dwpicker.toggle()
+```
+
+---
+
+### 3. MG-Picker Studio
+
+**Python 命令（Animator 模式）：**
+```python
+import animation_tools.mgpicker as mgpicker
+mgpicker.start()
+```
+
+**Python 命令（Designer 模式）：**
+```python
+import animation_tools.mgpicker as mgpicker
+mgpicker.start(mode=0)
+```
+
+**MEL 命令：**
+```mel
+python("import animation_tools.mgpicker as mgpicker; mgpicker.start()");
+```
+
+---
+
+### 4. IK/FK Switcher
+
+**Python 命令：**
+```python
+import animation_tools.ik_fk_switcher as ikfk
+ikfk.show()
+```
+
+**MEL 命令：**
+```mel
+python("import animation_tools.ik_fk_switcher as ikfk; ikfk.show()");
+```
+
+---
+
+## 📝 创建工具架按钮步骤
+
+### 方法 1：通过 Maya UI
+
+1. 打开 **Script Editor**（脚本编辑器）
+2. 在 **Python** 标签页输入命令
+3. 选中代码
+4. **鼠标中键拖拽** 到工具架
+5. 右键点击按钮 → **Edit** → 设置图标和标签
+
+### 方法 2：通过 MEL 命令
+
+```mel
+// Studio Library
+shelfButton
+    -command "python(\"import animation_tools.studiolibrary as studiolib; studiolib.show()\")"
+    -annotation "Studio Library"
+    -label "StudioLib"
+    -image "commandButton.png"
+    -imageOverlayLabel "SL";
+
+// DreamWall Picker
+shelfButton
+    -command "python(\"import animation_tools.dwpicker as dwpicker; dwpicker.show()\")"
+    -annotation "DreamWall Picker"
+    -label "DWPicker"
+    -image "commandButton.png"
+    -imageOverlayLabel "DW";
+
+// MG-Picker
+shelfButton
+    -command "python(\"import animation_tools.mgpicker as mgpicker; mgpicker.start()\")"
+    -annotation "MG-Picker Studio"
+    -label "MGPicker"
+    -image "commandButton.png"
+    -imageOverlayLabel "MG";
+
+// IK/FK Switcher
+shelfButton
+    -command "python(\"import animation_tools.ik_fk_switcher as ikfk; ikfk.show()\")"
+    -annotation "IK/FK Switcher"
+    -label "IK/FK"
+    -image "commandButton.png"
+    -imageOverlayLabel "IK";
+```
+

+
+## 🎨 推荐的按钮图标
+
+### Studio Library
+- **图标**: `UVEditorSnapshot.png` 或 `folder-open.png`
+- **标签**: `SL` 或 `Studio`
+
+### DreamWall Picker
+- **图标**: `pickHandlesComp.png` 或 `pickOtherComp.png`
+- **标签**: `DW` 或 `Picker`
+
+### MG-Picker
+- **图标**: `pickWalkUp.png` 或 `selectByHierarchy.png`
+- **标签**: `MG` 或 `MGPick`
+
+### IK/FK Switcher
+- **图标**: `ikSCsolver.png` 或 `kinHandle.png`
+- **标签**: `IK` 或 `Switch`
+
+---
+
+## ⚠️ 常见问题
+
+### 问题 1: ModuleNotFoundError: No module named 'animation_tools'
+
+**原因**: `animation_tools` 不在 Python 路径中
+
+**解决方案**:
+1. 检查 `userSetup.py` 是否正确设置
+2. 或在按钮命令前添加路径：
+   ```python
+   import sys
+   scripts_path = r'h:\Workspace\Raw\Tools\Plugins\Maya\2023\scripts'
+   if scripts_path not in sys.path:
+       sys.path.insert(0, scripts_path)
+   
+   import animation_tools.studiolibrary as studiolib
+   studiolib.show()
+   ```
+
+### 问题 2: 工具重复打开
+
+**原因**: 没有使用正确的启动命令
+
+**解决方案**: 使用本文档中的标准命令，所有工具都有窗口管理机制
+
+### 问题 3: 版本不兼容
+
+**原因**: 使用了错误的 Maya 版本目录
+
+**解决方案**: 
+- Maya 2023 使用: `Maya\2023\scripts`
+- Maya 2024 使用: `Maya\2024\scripts`
+- Maya 2025 使用: `Maya\2025\scripts`

+## 📦 完整的 userSetup.py 示例
+
+创建或编辑: `Documents/maya/scripts/userSetup.py`
+
+```python
+#!/usr/bin/env python
+# -*- coding: utf-8 -*-
+
+"""
+Maya User Setup
+自动加载动画工具路径
+"""
+
+import sys
+import os
+import maya.cmds as cmds
+
+def setup_animation_tools():
+    """设置动画工具路径"""
+    # 获取 Maya 版本
+    maya_version = cmds.about(version=True).split('.')[0]
+    
+    # 构建路径
+    base_path = r'h:\Workspace\Raw\Tools\Plugins\Maya'
+    scripts_path = os.path.join(base_path, maya_version, 'scripts')
+    
+    # 添加到 Python 路径
+    if os.path.exists(scripts_path):
+        if scripts_path not in sys.path:
+            sys.path.insert(0, scripts_path)
+        print("Animation tools loaded from: " + scripts_path)
+    else:
+        print("Warning: Animation tools path not found: " + scripts_path)
+
+# 在 Maya 启动时执行
+if __name__ == '__main__':
+    cmds.evalDeferred(setup_animation_tools)
+```
+
+---
+
+## ✅ 验证安装
+
+在 Maya Script Editor 中运行：
+
+```python
+import sys
+print("Python paths:")
+for path in sys.path[:5]:
+    print("  -", path)
+
+print("\nTesting imports:")
+try:
+    import animation_tools.studiolibrary
+    print("  ✓ Studio Library")
+except ImportError as e:
+    print("  ✗ Studio Library:", e)
+
+try:
+    import animation_tools.dwpicker
+    print("  ✓ DreamWall Picker")
+except ImportError as e:
+    print("  ✗ DreamWall Picker:", e)
+
+try:
+    import animation_tools.mgpicker
+    print("  ✓ MG-Picker")
+except ImportError as e:
+    print("  ✗ MG-Picker:", e)
+
+try:
+    import animation_tools.ik_fk_switcher
+    print("  ✓ IK/FK Switcher")
+except ImportError as e:
+    print("  ✗ IK/FK Switcher:", e)
+```
+
+预期输出：
+```
+Python paths:
+  - h:\Workspace\Raw\Tools\Plugins\Maya\2023\scripts
+  - ...
+
+Testing imports:
+  ✓ Studio Library
+  ✓ DreamWall Picker
+  ✓ MG-Picker
+  ✓ IK/FK Switcher
+```
+
+---
+
+## 🚀 快速启动所有工具
+
+```python
+# 一键启动所有动画工具
+import animation_tools.studiolibrary as studiolib
+import animation_tools.dwpicker as dwpicker
+import animation_tools.mgpicker as mgpicker
+import animation_tools.ik_fk_switcher as ikfk
+
+studiolib.show()
+dwpicker.show()
+mgpicker.start()
+ikfk.show()
+```
+
+---
+
+## 📞 支持
+
+如果遇到问题：
+
+1. 检查 Python 路径是否正确
+2. 检查 Maya 版本是否匹配
+3. 查看 Script Editor 的完整错误信息
+4. 确认所有文件都在正确的位置
+
