cocos2dx3.x tolua

请确保你运行引擎自带的\frameworks\cocos2d-x\tools\tolua\genbindings.py 是成功的

目录结构

1.你必须知道你的目录结构，下面说说我的目录结构
cocos_root: F:\LuaFrameWork_3.13.1\frameworks\cocos2d-x
Class: F:\LuaFrameWork_3.13.1\frameworks\runtime-src\Classes

下面这个是我的演示目录，是py文件和ini和需要转换成lua的cpp文件都丢到这里面
F:\LuaFrameWork_3.13.1\frameworks\runtime-src\Classes\AsioNet\tolua3.13

编写py文件

到 $(cocos_root)\tools\tolua 下拷贝genbindings.py 和 cocos2dx_ui.ini（随意吧，如果出问题建议和我一样）
修改命名 genbindings.py -》lua_asio_genbindings.py
cocos2dx_ui.ini -》lua_asio.ini

讲解 你可以在代码里面找到对应的代码，请注意看注释

// 这里本意是cocos_root路径，
而我的演示目录在F:\LuaFrameWork_3.13.1\frameworks\runtime-src\Classes\AsioNet\tolua3.13
所以我需要将project_root 索引到cocosx路径

os.path.join(os.path.dirname(_file_) 这个等于py的路径，就是你编写的py所存放的路径，
相当于我的目录F:\LuaFrameWork_3.13.1\frameworks\runtime-src\Classes\AsioNet\tolua3.13

project_root = os.path.abspath(os.path.join(os.path.dirname(file), ‘..’, ‘..’)) // 源代码

 //修改后的代码, 这是你需要的，这是你需要修改的第一个位置project_root = os.path.abspath(os.path.join(os.path.dirname(__file__), '..', '..', '..', '..', "cocos2d-x"))

cocos_root = os.path.abspath(os.path.join(project_root, ''))cxx_generator_root = os.path.abspath(os.path.join(project_root, 'tools/bindings-generator'))# save config to fileconfig = ConfigParser.ConfigParser()config.set('DEFAULT', 'androidndkdir', ndk_root)config.set('DEFAULT', 'clangllvmdir', llvm_path)config.set('DEFAULT', 'cocosdir', cocos_root)config.set('DEFAULT', 'cxxgeneratordir', cxx_generator_root)config.set('DEFAULT', 'extra_flags', '') try:    tolua_root = '%s/tools/tolua' % project_root// 源代码    output_dir = '%s/cocos/scripting/lua-bindings/auto' % project_root//源代码

    // 第2个位置        // project_root相当于cocos-x的目录，        tolua_root = '%s/../runtime-src/Classes/AsioNet/tolua3.13' % project_root// 你需要转换的cpp文件路径        output_dir = '%s/../runtime-src/Classes/AsioNet/tolua3.13' % project_root// 生成后的lua目录

    //修改后的    cmd_args = {'lua_asio.ini' : ('lua_asio', 'tolua_asio') }    target = 'lua'    generator_py = '%s/generator.py' % cxx_generator_root

运行你的py文件

在编写ini文件

[lua_asio] // 需修改成ini的文件名# the prefix to be added to the generated functions.

如果你看不懂，你可以参考其他人的配置，但是我注释的地方，你可以参考下

踩过的坑

raise ValueError(“no path specified”) 如果报这个错误，可能是你headers写了头文件 而classes没写

如果你的导出文件包含很多外部头文件，可能会一直报错，这时候你最好是在封装一层，这样就可以轻松导出
比如你原本要导出A文件，但是一直报第三方的库的头文件错误，这时候你在把A封装到B，保证B的.h文件不使用到第三方的文件即可。
