Cocos2dx(3.3)绑定lua 参考：http://blog.sina.com.cn/s/blog_693de6100101ocg4.html http://segmentfault.com/blog/hongliang/1190000000631630 1、安装必要的库和工具包，以及配置相关环境变量，请按照cocos2d-x-3.0rc0toolstoluaREADME.mdown说得去做，不赘述。 绑定lua必须安装的两个软件PyYAML、Cheetah这两个软件 2、写c++类(我测试用的是Mytestl1/frameworks/runtime-src/Classes/HelloWorldScene.cpp) 3、写一个生成的python脚本，你不会写，没关系，我们会照猫画虎 1）进入目录Mytestl1/frameworks/cocos2d-x/tools/tolua，复制一份genbindings.py，命名为genbindings_myclass.py 2）把生成目录制定到咱工程里去，打开genbindings_myclass.py把
---------------------------------------------- output_dir = '%s/cocos/scripting/lua-bindings/auto'% project_root ---------------------------------------------- 改成 ---------------------------------------------- output_dir = '%s/../runtime-src/Classes/auto' %project_root ---------------------------------------------- 3）修改命令参数,把 ---------------------------------------------- cmd_args = {'cocos2dx.ini' : ('cocos2d-x','lua_cocos2dx_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'), } ---------------------------------------------- 改成 ---------------------------------------------- cmd_args = {'myclass.ini' : ('myclass','lua_myclass_auto') } 4）这时你可能问myclass.ini在哪啊，我们下来就写这个文件。原理一样，我还是照猫画虎，拿cocos2dx_spine.ini改的。 [myclass] # the prefix to be added to the generatedfunctions. You might or might not use this in your own # templates prefix = myclass # create a target namespace (in javascript,this would create some code like the equiv. to `ns = ns || {}`) # all classes will be embedded in thatnamespace target_namespace =

Please define NDK_ROOT in yourenvironment." sys.exit(1) return NDK_ROOT 或者你可以在终端里边执行export /Users/zctech_10/Tools/adt-bundle-mac-x86_64-20130917/android-ndk-r9b命令 这里一定要使用android-ndk-r9b，而不是android-ndk-r9 2、在编写genbindings_myclass.py文件的时候，写关于output_dir路径的坑 output_dir= '%s/../runtime-src/Classes/auto' %project_root 这个要写你自己的Classes的路径（或许你可以写成其他的路径，暂时还没试验其他的路径是否ok） 3、在编写myclass.ini文件的时候， headers= %(cocosdir)s/../runtime-src/Classes/HelloWorldScene.h 一定要写的是HelloWorldScene.h文件的路径，不然就会报错，如果你需要绑定的文件是其他的文件，你就写你自己需要绑定的文件 4、第四个坑就是绑定成功了，但是一运行就会报错 修改如下： AppDelegate.cpp文件中修改 lua_State *L =stack->getLuaState(); lua_getglobal(L,"_G"); register_all_MyClass(L); lua_settop(L,0); 重新编译并执行，程序就正确执行了： 注意代码的顺序
关于绑定lua 遇到的一些坑 没用的头文件要去掉 不能有cc_ex_dll 名字空间转换在conversions.yaml设置 每个类名都要写 安装 Cheetah-2.4.4PyYAML-3.11 sudo python ./setup.py install （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
