首先进入准备工作

1.安装软件

打开终端，逐条执行下面的命令

sudo easy\_install pip       
sudo pip install PyYAML     
sudo pip install Cheetah  
\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
pip是一个安装和管理Python包的工具  
PyYAML是一个Python的YAML解析器，这是一种数据序列化语言，是一种可读的文本的数据结构，它的设计目标是使人们容易读，程序容易处理。它类似XML，但是比XML简单。  
Cheetah提供了一门简单语言，用来定义提供基本流控制和对象访问构造的模板。  
2.增加NDK\_ROOT，必须是android-ndk-r9b及以上  
  
二:编写自己的c++代码  
\#ifndef \_HELLO\_H\_  
\#define \_HELLO\_H\_  
\#include "cocos2d.h"  
namespace cocos2d \{  
class Hello : public cocos2d::Ref\{  
public:  
    Hello()\{\};  
    ~Hello()\{\};  
    bool init()\{return true;\};  
    static cocos2d::Hello\* create()  
    \{  
           Hello \*h = new Hello();  
           if(h && h->init())\{  
            h->autorelease();  
            return h;  
           \}  
           return NULL;  
    \};  
    void myprint()\{log("Hello Hello");\};  
  \};  
\}  
\#endif  
  
三:编写cocos2dx\_hello.ini  
1.在项目的frameworks/cocos2d-x/tools/tolua/下创建一个文件cocos2dx\_hello.ini。

2.将以下内容：

[cocos2dx_custom]
    
    # the prefix to be added to the generated functions. You might or might
    not use this in your own
    
    # templates
    
    prefix = cocos2dx_custom
    
    # 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
    
    target_namespace = cc
    
    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/my -I%(cocosdir)s/cocos/2d -I%(cocosdir)s/cocos/base -I%(cocosdir)s/cocos/ui -I%(cocosdir)s/cocos/physics -I%(cocosdir)s/cocos/2d/platform -I%(cocosdir)s/cocos/2d/platform/android -I%(cocosdir)s/cocos/math/kazmath -I%(cocosdir)s/extensions -I%(cocosdir)s/external -I%(cocosdir)s/cocos/editor-support -I%(cocosdir)s
    
    cocos_flags = -DANDROID -DCOCOS2D_JAVASCRIPT
    
    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
    
    headers = %(cocosdir)s/cocos/my/CustomClass.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 = CustomClass.*
    
    # 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.
    
    skip =
    
    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 =
    
    # 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

拷贝到cocos2dx\_hello.ini中。

3.修改cocos2dx\_hello.ini文件。  
   A.第1行的名字 \[cocos2dx\_hello\]  
   B.第4行注释掉 \#not use this in your own  
   C.第8行的前缀 prefix = cocos2dx\_hello  
   D.第15行的命名空间 target\_namespace = cc  
   E.第37行的头文件  headers = %(cocosdir)s/cocos/my/Hello.h  
   F.第43行的类名    classes = Hello.\*  
4.修改genbindings.py文件  
   修改136行的 cmd\_args在最后加上  
   'cocos2dx\_hello.ini' : ('cocos2dx\_hello', 'lua\_cocos2dx\_hello\_auto'), \\  
5.打开终端，进入到frameworks/cocos2d-x/tools/tolua/目录，输入export PYTHON\_BIN=/usr/bin/python  
6.执行genbindings.py  
  在项目的framework/cocos2d-x/cocos/scripting/lua-bindings/auto/目录中会有lua\_cocos2dx\_hello\_auto.cpp和lua\_cocos2dx\_hello\_auto.hpp文件。  
  四:在lua中使用  
  1.使用Xcode6.1打开项目  
2.lua\_cocos2dx\_hello\_auto.cpp导入到项目  
3.build settings的User Header Search paths debug中增加$(SRCROOT)/../../cocos2d-x/cocos/my  
4.在lua\_module\_register.h中导入\#include “lua\_cocos2dx\_hello\_auto.hpp"头文件  
5.lua\_module\_register.h中int lua\_module\_register(lua\_State\* L)方法中增加  
lua\_getglobal(L,"\_G");  
    if(lua\_istable(L,-1))  
    \{  
        register\_all\_cocos2dx\_hello(L);  
    \}  
    lua\_pop(L,1);  
6.在MainScene.lua中编写local h = cc.Hello:create();  
    h:myprint();  
7.运行项目，可以看到“Hello Hello”
