这里有篇文章,看三和四。
按上面操作,文件都不缺少的,可以直接看 2. 和 3 .
记住:player3 来打开项目, 的类格式化后,放到他的源代码路径下面, 解释生成的lua 也要放到 api下面
player3 重新生成就可以了
player3 最后打开可能会出现, a nil value。
其实,我们用cocos2d-x-3.10,
D:\cocos\setup\Cocos2d-x\cocos2d-x-3.10\tools\tolua
genbindings.py **.ini 来转换成 lua能够调用的 类。
其实就是通过D:\cocos\setup\Cocos2d-x\cocos2d-x-3.10\tools\tolua下提供:README.mdown.的说明来配置,最后生成lua api函数。——这里不妨称这一套东西为c++ 转成 lua 的 解释器或者解释工具,转换工具也成。
我的环境:
win 7 64 位, Sublime Text 3, Quick-Cocos2dx-Community3.6(桌面快捷方式player3) vs 2013
Quick-Cocos2dx-Community 3.6 我没有转换成功,就用
cocos2d-x-3.10 转换,成功了
========================================================
以上才只是编译环境简单说明:
Quick-Cocos2dx-Community 最好,现在这个下面试试, 我的是在
G:\Game\Quick-Cocos2dx-Community\tools\tolua
下面,按住shift + 右键点击选择 “在此处打开命令窗口”直接运行 python genbindings.py。 试试你的Quick-Cocos2dx-Community 能不能转换。
如果不行,也没有关系,这个时候,需要 cocos2d-x 引擎来处理, 我的是 cocos2d-x-3.10。
1. 把自己的类,.h .cpp 放到 G:\ademo\frameworks\runtime-src\Classes 这个下面 “runtime-src\Classes”, 这里的工程是G:\下的 ademo,
(名字有点怪, demo 前面加个a 是便于 player3 打开项目是 目录 在最上面。)
接下来是 cocos2d-x-3.10解压安装目录下
D:\cocos\setup\Cocos2d-x\cocos2d-x-3.10\tools\tolua
cocos2dx.ini
, genbindings.py 各复制一份 修改名称
修改下面的配置 :Pet.ini Pet.py
[Pet] prefix = Pet 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 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 # what headers to parse headers = %(cocosdir)s/cocos/scripting/lua-bindings/auto/Pet.h #headers = G:/aatestlua/frameworks/runtime-src/Classes/Pet.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 = Pet # 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
我使用绝对路径没有成功。
我就顺便把自己的类 Pet.h 放到成才 lua 格式c++ 类同一目录下(runtime-src\Classes自己的c++类)。
%(cocosdir)s/cocos/scripting/lua-bindings/auto/
就是这个目录
下面看Pet.py
这个里面 改的地方不多:
try: tolua_root = '%s/tools/tolua' % project_root output_dir = '%s/cocos/scripting/lua-bindings/auto' % project_root cmd_args = { #'cocos2dx.ini' : ('cocos2d-x', 'lua_cocos2dx_auto'), 'Pet.ini' : ('Pet', 'lua_pet_auto'), #'cocos2dx_assetsmanager.ini' : ('cocos2dx_assetsmanager', 'lua_cocos2dx_assetsmanager_auto'), #'cocos2dx_extension.ini' : ('cocos2dx_extension', 'lua_cocos2dx_extension_auto'), #'cocos2dx_ui.ini' : ('cocos2dx_ui', 'lua_cocos2dx_ui_auto'), #'cocos2dx_studio.ini' : ('cocos2dx_studio', 'lua_cocos2dx_studio_auto'), #'cocos2dx_spine.ini' : ('cocos2dx_spine', 'lua_cocos2dx_spine_auto'), #'cocos2dx_physics.ini' : ('cocos2dx_physics', 'lua_cocos2dx_physics_auto'), #'cocos2dx_experimental_video.ini' : ('cocos2dx_experimental_video', 'lua_cocos2dx_experimental_video_auto'), #'cocos2dx_experimental.ini' : ('cocos2dx_experimental', 'lua_cocos2dx_experimental_auto'), #'cocos2dx_controller.ini' : ('cocos2dx_controller', 'lua_cocos2dx_controller_auto'), #'cocos2dx_cocosbuilder.ini': ('cocos2dx_cocosbuilder', 'lua_cocos2dx_cocosbuilder_auto'), #'cocos2dx_cocosdenshion.ini': ('cocos2dx_cocosdenshion', 'lua_cocos2dx_cocosdenshion_auto'), #'cocos2dx_3d.ini': ('cocos2dx_3d', 'lua_cocos2dx_3d_auto'), #'cocos2dx_audioengine.ini': ('cocos2dx_audioengine', 'lua_cocos2dx_audioengine_auto'), #'cocos2dx_csloader.ini' : ('cocos2dx_csloader', 'lua_cocos2dx_csloader_auto'), } target = 'lua' generator_py = '%s/generator.py' % cxx_generator_root for key in cmd_args.keys(): args = cmd_args[key] cfg = '%s/%s' % (tolua_root, key) print 'Generating bindings for %s...' % (key[:-4]) command = '%s %s %s -s %s -t %s -o %s -n %s' % (python_bin, generator_py, cfg, args[0], target, output_dir, args[1]) _run_cmd(command) if platform == 'win32': with _pushd(output_dir): _run_cmd('dos2unix *')
只需要 在 cmd_args = { }中 把不需要的 注释掉,这样 解释起来 快点
tolua_root
= ‘%s/tools/tolua‘ % project_root
output_dir = ‘%s/cocos/scripting/lua-bindings/auto‘ % project_root
这里的两个目录,上面的是 我修改 .ini 和 .py 的目录,下面的是 生成的目录, 我们需要 解释的类放的目录, 上面有提到这个目录
好了贴一下这个配置,以免有遗漏的地方

接下来, 开始 按住 shift键 右键 单击当前 文件夹 空白 选中 “当前窗口打开命令窗口”
输入: python Pet.py
成功是 会出现 lua binding succeeds.
接下来 会出现 四个文件,
D:\cocos\setup\Cocos2d-x\cocos2d-x-3.10\cocos\scripting\lua-bindings\auto
lua格式的c++ 类 lua_pet_auto.hpp lua_pet_auto.cpp
D:\cocos\setup\Cocos2d-x\cocos2d-x-3.10\cocos\scripting\lua-bindings\auto\api
lua_pet_auto_api.lua Pet.lua
这里需要注意:有的 没有生成 Pet.lua 是因为你的 .ini 下面 class= Pet 没有指定要生成的类。
2. 需要用 vs 2013 来检验 ,调用 。 本文开头的链接 将的很清楚,这里就不啰嗦了。
可能到最后,vs 2013 打开运行 没有问题,但是 lua 直接用 player3 打开工程 会有问题******(a nil value).
function MainScene:ctor() cc.ui.UILabel.new({ UILabelType = 2, text = "Hello, World", size = 64}) :align(display.CENTER, display.cx, display.cy) :addTo(self) pet = Pet:new() print(strhello); strhello = pet:getTestText(); local mPet = pet:addTo(self) print("===============调用成功===================") cc.ui.UILabel.new({ UILabelType = 2, text = strhello, size = 32}) :align(display.CENTER, display.cx, display.cy + 100) :addTo(self) end你要确保你的vs工程下面 libluacocos2d -auto : lua_pet_auto.cpp 和 lua_pet_auto.hpp 存在。
这个我是放在 player3 源代码 路径下的:G:\Game\Quick-Cocos2dx-Community\cocos\scripting\lua-bindings\auto
可以直接 右键属性, c++ 头文件路径导入 绝对路径 G:\ademo\frameworks\runtime-src\Classes\
Pet.h Pet.cpp
这里配置成功后, 后面需要打开的另一个工程就不需要配置了。
你的工程 下(这里我的是ademo) 下面 右键属性 G:\Game\Quick-Cocos2dx-Community\cocos\scripting\lua-bindings\auto
lua_pet_auto.cpp 和 lua_pet_auto.hpp 存在
G:\Game\Quick-Cocos2dx-Community\cocos\scripting\lua-bindings\auto\api
lua_pet_auto_api.lua 和 Pet.lua 存在
就是 把 cocos2d-x-3.10 下成才的东西 player3 在放置一下,因为你是用 player3吗,对吧!
注意:你用的是player3 ,但此时,为什么没有成功,这是为什么呢? 嘿嘿。
虽说你的 lua_pet_auto.cpp 和 lua_pet_auto.hpp 也放到 player3 的资源目录下啦(G:\Game\Quick-Cocos2dx-Community\cocos\scripting\lua-bindings\auto)
lua_pet_auto_api.lua 和 Pet.lua
也在 G:\Game\Quick-Cocos2dx-Community\cocos\scripting\lua-bindings\auto\api 下了。
为什么呢?
—— vs 打开工程 重新构建 ,build all 。 把所有的东西 整合。
因为 你用的 player3 ,是编译生成好的 。
3. 那好,我们来操作....
G:\Game\Quick-Cocos2dx-Community\quick\player
找到 proj.win32 vs 打开 解决方案 player.sln 重新 生成解决方案。
返回到上级目录 :G:\Game\Quick-Cocos2dx-Community\quick\player
win32 文件夹 ,就是 你的 player3(桌面没有的 ,右键桌面快捷方式)
重新生成解决方案后,打开看看,是不是成功了。
注意:vs 打开 解决方案 player.sln 下 项目 libluacocos2d 和你工程的 应该是一样的, 这也是上面我们提到的你会用到的。
只需要 player3 工程 下 class 右键添加
G:\Game\Quick-Cocos2dx-Community\quick\player\Classes\ Pet.h Pet.cpp 这里是从你的工程下 “\frameworks\runtime-src\Classes” 下哪来的
这也是 为什么 开始 让你 Quick-Cocos2dx-Community 下试试 能不能运行成功的原因, 成功了,就不需要 cocos2d-x-3.10 来生成
直接 在G:\Game\Quick-Cocos2dx-Community\tools\tolua 生成, 后面不要 复制过来复制过去了。
好了完了。
补充:
http://www.cocoachina.com/bbs/read.php?tid=200145
vs 调用 自己的类注意事项:
bool AppDelegate::applicationDidFinishLaunching() { LuaEngine * lua_engine = LuaEngine::getInstance(); ScriptEngineManager::getInstance()->setScriptEngine(lua_engine); lua_State* luaState = lua_engine->getLuaStack()->getLuaState(); if (L) { lua_getglobal(luaState, "_G"); register_all_Pet(luaState); lua_settop(luaState, 0); } //register custom function //LuaStack* stack = engine->getLuaStack(); //register_custom_function(stack->getLuaState()); //FileUtils::getInstance()->setResourceEncryptKeyAndSign("test", "XXTEA"); }
