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。

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C++中的方法名，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。

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。
