Lua中調用C++方法

目前項目，使用了Lua腳本，至於使用Lua的好處再也不贅述了。因而對Tolua作了一些小小的學習，總結一下吧。

主要說一下如何在Lua中調用Ｃ＋＋方法。

Lua調用C++的橋樑，是tolua。tolua是什麼，http://blog.csdn.net/killwd/article/details/1423923 這篇文章介紹的很詳細。

咱們須要手動作的，其實即是編寫中間類，這個類被tolua直接使用，最終的目的是實現lua中對象方法和C++中對象方法的對應。

 

LuaCocos2d.cpp 完成了全部基本的cocos對象方法的轉換，咱們把它稱之爲一個橋樑。LuaCocos2d.cpp 是在CCLuaStack 中的init函數中調用的。

 tolua_Cocos2d_open(m_state);

 

1.CCLuaStack 中調用中間橋樑（好比LuaCocos2d）

2.橋樑裏面（好比LuaCocos2d）實現各類方法的轉換

這樣，整個的重點就是橋樑的生成了。

看一下LuaCocos2d ，最重要的方法我認爲是tolua_reg_types。

 拿CCLabelTTF舉例，你在裏面搜即可以明白了。第一個參數先不用管，第二個是CCLabelTTF在調用的方法名，第三個參數即是這個文件中定義的方法，你找到一看便會明白了。

假如咱們有本身的C++方法須要在Lua中調用，也按照這兩個大步驟完成便可。中間橋樑類參考LuaCocos2d.cpp便可。
