Lua中调用C++方法
目前项目，使用了Lua脚本，至于使用Lua的好处不再赘述了。于是对Tolua做了一些小小的学习，总结一下吧。
主要说一下如何在Lua中调用Ｃ＋＋方法。
Lua调用C++的桥梁，是tolua。tolua是什么，http://blog.csdn.net/killwd/article/details/1423923 这篇文章介绍的很详细。
我们需要手动做的，其实便是编写中间类，这个类被tolua直接使用，最终的目的是实现lua中对象方法和C++中对象方法的对应。
LuaCocos2d.cpp 完成了所有基本的cocos对象方法的转换，我们把它称之为一个桥梁。LuaCocos2d.cpp 是在CCLuaStack 中的init函数中调用的。
tolua_Cocos2d_open(m_state);
1.CCLuaStack 中调用中间桥梁（比如LuaCocos2d）
2.桥梁里面（比如LuaCocos2d）实现各种方法的转换
这样，整个的重点就是桥梁的生成了。
看一下LuaCocos2d ，最重要的方法我认为是tolua_reg_types。
/* function to register type */
static void tolua_reg_types (lua_State* tolua_S)

拿CCLabelTTF举例，你在里面搜便可以明白了。第一个参数先不用管，第二个是CCLabelTTF在调用的方法名，第三个参数便是这个文件中定义的方法，你找到一看便会明白了。
#ifdef __cplusplus tolua_cclass(tolua_S,"CCLabelTTF","CCLabelTTF","CCSprite",tolua_collect_CCLabelTTF); #else tolua_cclass(tolua_S,"CCLabelTTF","CCLabelTTF","CCSprite",NULL); #endif tolua_beginmodule(tolua_S,"CCLabelTTF"); tolua_function(tolua_S,"new",tolua_Cocos2d_CCLabelTTF_new00); tolua_function(tolua_S,"new_local",tolua_Cocos2d_CCLabelTTF_new00_local); tolua_function(tolua_S,".call",tolua_Cocos2d_CCLabelTTF_new00_local); tolua_function(tolua_S,"delete",tolua_Cocos2d_CCLabelTTF_delete00); tolua_function(tolua_S,"create",tolua_Cocos2d_CCLabelTTF_create00); tolua_function(tolua_S,"create",tolua_Cocos2d_CCLabelTTF_create01); tolua_function(tolua_S,"create",tolua_Cocos2d_CCLabelTTF_create02); tolua_function(tolua_S,"create",tolua_Cocos2d_CCLabelTTF_create03); tolua_function(tolua_S,"initWithString",tolua_Cocos2d_CCLabelTTF_initWithString00); tolua_function(tolua_S,"initWithString",tolua_Cocos2d_CCLabelTTF_initWithString01); tolua_function(tolua_S,"initWithString",tolua_Cocos2d_CCLabelTTF_initWithString02); tolua_function(tolua_S,"initWithStringAndTextDefinition",tolua_Cocos2d_CCLabelTTF_initWithStringAndTextDefinition00); tolua_function(tolua_S,"init",tolua_Cocos2d_CCLabelTTF_init00); tolua_function(tolua_S,"setTextDefinition",tolua_Cocos2d_CCLabelTTF_setTextDefinition00); tolua_function(tolua_S,"getTextDefinition",tolua_Cocos2d_CCLabelTTF_getTextDefinition00); tolua_function(tolua_S,"enableShadow",tolua_Cocos2d_CCLabelTTF_enableShadow00); tolua_function(tolua_S,"disableShadow",tolua_Cocos2d_CCLabelTTF_disableShadow00); tolua_function(tolua_S,"enableStroke",tolua_Cocos2d_CCLabelTTF_enableStroke00); tolua_function(tolua_S,"disableStroke",tolua_Cocos2d_CCLabelTTF_disableStroke00); tolua_function(tolua_S,"setFontFillColor",tolua_Cocos2d_CCLabelTTF_setFontFillColor00); tolua_function(tolua_S,"setString",tolua_Cocos2d_CCLabelTTF_setString00); tolua_function(tolua_S,"getString",tolua_Cocos2d_CCLabelTTF_getString00); tolua_function(tolua_S,"getHorizontalAlignment",tolua_Cocos2d_CCLabelTTF_getHorizontalAlignment00); tolua_function(tolua_S,"setHorizontalAlignment",tolua_Cocos2d_CCLabelTTF_setHorizontalAlignment00); tolua_function(tolua_S,"getVerticalAlignment",tolua_Cocos2d_CCLabelTTF_getVerticalAlignment00); tolua_function(tolua_S,"setVerticalAlignment",tolua_Cocos2d_CCLabelTTF_setVerticalAlignment00); tolua_function(tolua_S,"getDimensions",tolua_Cocos2d_CCLabelTTF_getDimensions00); tolua_function(tolua_S,"setDimensions",tolua_Cocos2d_CCLabelTTF_setDimensions00); tolua_function(tolua_S,"getFontSize",tolua_Cocos2d_CCLabelTTF_getFontSize00); tolua_function(tolua_S,"setFontSize",tolua_Cocos2d_CCLabelTTF_setFontSize00); tolua_function(tolua_S,"getFontName",tolua_Cocos2d_CCLabelTTF_getFontName00); tolua_function(tolua_S,"setFontName",tolua_Cocos2d_CCLabelTTF_setFontName00); tolua_endmodule(tolua_S);
假如我们有自己的C++方法需要在Lua中调用，也按照这两个大步骤完成即可。中间桥梁类参考LuaCocos2d.cpp即可。
