quick-3.5 绑定自定义C++类到Lua并使用cocos code ide 调式
在这里主要记录怎么绑定自定义C++类到Lua 参考文章在这里【绑定自定义类至Lua】，在我操作过程中略有不同，现在把步骤记录下来。 1.打开引擎目录下\tools\tolua\README.mdown，安装相应软件 2.项目目录\frameworks\cocos2d-x\tools\tolua,复制cocos2dx_cocosbuilder->custom.ini,genbindings->custom-genbindings.py 3.修改复制后的文件 custion.ini
\[custom_socket\]
\# the prefix to be added to the generated functions. You might or might not use this in your own
\# templates
prefix = custom_socket
\# 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 =
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

clang_headers = -I%(clangllvmdir)s/lib/clang/3.3/include

\# 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/../runtime-src/Classes/net/SocketModule.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 = ClientSocket.* CMD_Command.* ConnectHandler.* RecvHandler.*
\# 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主要修改： 第1行：[custom_socket] 第4行：prefix = custom_socket 第8行：target_namespace = 第26行：headers = %(cocosdir)s/../runtime-src/Classes/net/SocketModule.h 第30行：classes = ClientSocket.* CMD_Command.* ConnectHandler.* RecvHandler.* 其余根据具体来设置，主要说一下第26行是创建一个头文件，包含导出类的相关头文件，30行是导出的类定义 custom-genbindings.py

主要修改： 第134行： output\_dir = '%s/../runtime-src/Classes/lua-bindings/auto' % project\_root 第136行： cmd\_args = {'custom.ini' : ('custom\_socket', 'lua\_custom\_socket_auto'),\ } 修改好后，在命令行执行：custom-genbindings.py 如果没有错误的话会生成lua\_custom\_socket\_auto.hpp和lua\_custom\_socket\_auto.cpp 接下来注册自定义模块： 1.添加到工程  2.引入到AppDelegate  3.注册模块  使用cocos code IDE 1.2.0断点调试，由于使用调试的模拟器是另外一个程序quick-3.5/tools/simulator，所以需要将脚本生成的文件在simulator工程再添加一遍：  生成新的模拟器，然后在lua中测试，就可以调用自定义的C++类了
