首先在quick 3.5下新建一个项目，cd进入工具-bin目录下，输入：cocos new NB -l lua -d ./Projects。这样就新建了项目NB。进入：D:\NB\frameworks\cocos2d-x\tools\tolua 目录你会看见很多ini文件，首先打开README.mdown。这里面有环境的配置，为了方便以后的记忆，我还是写出来了。我是在win7下建的环境。

第一步：确定电脑中有`android-ndk-r9b`.

第二步：Download python2.7.3 (32bit) from (http://www.python.org/ftp/python/2.7.3/python-2.7.3.msi).

第三步：Add the installed path of python (e.g. C:\Python27) to windows environment variable named 'PATH'.

第四步：Download pyyaml from http://pyyaml.org/download/pyyaml/PyYAML-3.10.win32-py2.7.exe and install it.（这个很重要，不然会执行python时报错，什么yaml的错）

第五步：Download pyCheetah from https://raw.github.com/dumganhar/my_old_cocos2d-x_backup/download/downloads/Cheetah.zip,unzip it to "C:\Python27\Lib\site-packages"

第六步：Set environment variables (`NDK_ROOT`)

第七步：run "genbindings.py".

环境配好后，在D:\NB\frameworks\cocos2d-x\tools\tolua 目录下，看见genbindings.py，可以在里面改，也可以重新复制一份出来改。我是复制一份出来改的。

1、先说ini，任意打开一份ini，

[cocos2dx_spine]  （ini文件名）

<span style="color: rgb(85,85,85); font-family: 'Microsoft Yahei',sans-serif; font-size: 15px; line-height: 26px; text-indent: 30px;">#prefix会被添加到生成的函数.你也可以选择不添加这个到你的模板</span>
prefix = cocos2dx_spine 

# create a target namespace (in javascript,this would create some code like the equiv. to `ns = ns || {}`)
# all classes will be embedded in that namespace （命名空间）
target_namespace = sp

android_headers = -I%(androidndkdir)s/platforms/android-14/arch-arm/usr/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.7/libs/armeabi-v7a/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.7/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.8/libs/armeabi-v7a/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.8/include
android_flags = -D_SIZE_T_DEFINED_ 

clang_headers = -I%(clangllvmdir)s/lib/clang/3.3/include 
clang_flags = -nostdinc -x c++ -std=c++11 -U __SSE__

cocos_headers = -I%(cocosdir)s/cocos -I%(cocosdir)s/cocos/editor-support -I%(cocosdir)s/cocos/platform/android

cocos_flags = -DANDROID

cxxgenerator_headers = 

# extra arguments for clang
extra_arguments = %(android_headers)s %(clang_headers)s %(cxxgenerator_headers)s %(cocos_headers)s %(android_flags)s %(clang_flags)s %(cocos_flags)s %(extra_flags)s 

# what headers to parse （类所在路劲）
headers = %(cocosdir)s/cocos/editor-support/spine/spine-cocos2dx.h

# what classes to produce code for. You can use regular expressions here. When testing the regular
# expression,it will be enclosed in "^$",like this: "^Menu*$".
classes = SkeletonRenderer SkeletonAnimation （需要注册的类，有多个需要用空格空开）

# what should we skip? in the format ClassName::[function function]
# ClassName is a regular expression,but will be used like this: "^ClassName$" functions are also
# regular expressions,they will not be surrounded by "^$". If you want to skip a whole class,just
# add a single "*" as functions. See bellow for several examples. A special class name is "*",which
# will apply to all class names. This is a convenience wildcard to be able to skip similar named
# functions from all classes.
（在lua中不能访问的函数名，没有，=后面就不写）
skip = SkeletonRenderer::[findBone findSlot getAttachment setAttachment update draw createWithData],*::[update draw drawSkeleton],SkeletonAnimation::[setAnimationStateData createWithData addAnimation getCurrent setAnimation onAnimationStateEvent onTrackEntryEvent getState createWithFile]
（下面全空的默认OK）
rename_functions = 

rename_classes = 

# for all class names,should we remove something when registering in the target VM?
remove_prefix = 

# classes for which there will be no "parent" lookup
classes_have_no_parents = 

# base classes which will be skipped when their sub-classes found them.
base_classes_to_skip =

# classes that create no constructor
# Set is special and we will use a hand-written constructor
abstract_classes = Skeleton SkeletonAnimation

# Determining whether to use script object(js object) to control the lifecycle of native(cpp) object or the other way around. Supported values are 'yes' or 'no'.
script_control_cpp = no

2、在D:\NB\frameworks\runtime-src\Classes目录下编写自己的类，也可以在其他目录下。

（这个是引用：http://segmentfault.com/a/1190000000631630）

MyClass.h

#pragma once
#include "cocos2d.h"

using namespace cocos2d;

class MyClass : public Ref
{
public:
  MyClass()   {};
  ~MyClass()  {};
  bool init() { return true; };
  CREATE_FUNC(MyClass);

  int foo(int i);
};

#include "MyClass.h"

int MyClass::foo(int i)
{
  return i + 100;
}

[MyClass] （改）
prefix = MyClass (改)
target_namespace = my （改）
android_headers = -I%(androidndkdir)s/platforms/android-14/arch-arm/usr/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.7/libs/armeabi-v7a/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.7/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.8/libs/armeabi-v7a/include -I%(androidndkdir)s/sources/cxx-stl/gnu-libstdc++/4.8/include
android_flags = -D_SIZE_T_DEFINED_ 
clang_headers = -I%(clangllvmdir)s/lib/clang/3.3/include 
clang_flags = -nostdinc -x c++ -std=c++11 -U __SSE__
cocos_headers = -I%(cocosdir)s/cocos -I%(cocosdir)s/cocos/editor-support -I%(cocosdir)s/cocos/platform/android
cocos_flags = -DANDROID
cxxgenerator_headers = 
extra_arguments = %(android_headers)s %(clang_headers)s %(cxxgenerator_headers)s %(cocos_headers)s %(android_flags)s %(clang_flags)s %(cocos_flags)s %(extra_flags)s 
headers = %(cocosdir)s/../runtime-src/Classes/MyClass.h （改，这是自己类路劲，可以自己改）
classes = MyClass （改）
skip =  （改）
rename_functions = 
rename_classes =
remove_prefix = 
classes_have_no_parents = 
base_classes_to_skip = Ref ProcessBase
abstract_classes = 
script_control_cpp = no

output_dir = '%s/cocos/scripting/lua-bindings/auto' % project_root （这个路径是生成lua_MyClass_auto 的路径，可以自己改）
cmd_args = { 'MyClass.ini' : ('MyClass','lua_MyClass_auto')} 只生成MyClass的注册类。

5、在D:\NB\frameworks\cocos2d-x\tools\tolua目录下，执行python genbindings_myclass.py。没问题的话，你会在output_dir的路径下看见

lua_MyClass_auto.cpp 和 lua_MyClass_auto.hpp 两个文件。

在D:\NB\frameworks\cocos2d-x\cocos\scripting\lua-bindings\auto\api目录下看见MyClass.lua
6、在D:\NB\frameworks\runtime-src\Classes\AppDelegate.cpp中加入：#include "lua_MyClass_auto.hpp"

在LuaEngine* engine = LuaEngine::getInstance();后面加入：register_all_myclass(engine->getLuaStack()->getLuaState());

7、编译运行，这样，MyClass这个类就被导出到lua了

8、在main.lua中尝试：

local test = my.MyClass:create()
print("lua bind: " .. test:foo(99))

（仅个人理解，如有不对，还请指正）
