tolua++ Trial Demo

Always know that cocos2dx Lua is exported through the tolua++ LUA interface, but has not been self-directed, recently relatively idle, tried the next.

My environment is: Ubuntu, after installing the tolua++, you can try the tolua++ tool to export under the command line.

MyClass.cpp file:

#include <iostream> #include "tolua++.h" class Myclass{public:void Say () {std::cout << "Hello Wor    ld! "<< Std::endl; }};

tolua++ need to write pkg file, similar to C + + 's. h file, then remove the keyword, myclass.pkg

#include "MyClass.h" class myclass{MyClass ();    ~myclass (); void say ();};

In terminal execution:

tolua++-o MyClass.cpp myclass.pkg//-o MyClass.cpp means writing to the MyClass.cpp file.

After execution, the MyClass.cpp file will be generated, open will find a good hundreds of lines of code, there will be a

Tolua_api int Luaopen_myclass (lua_state* tolua_s)

, and then include a reference to the MyClass.h file in the file :

#include "string.h" #include "tolua++.h" ... #include "MyClass.h" ... Tolua_api int Luaopen_myclass (lua_state* tolua_s)//This method is the method to be exported to Lua

Add the function declaration in the MyClass.h file:

/* Exported function */tolua_api int tolua_myclass_open (lua_state* tolua_s);

MyTest. Lua Test files:

Local my = MyClass () My:say ()

Execute LUA through the main.cpp file.

#include  <iostream> #ifdef  __cplusplus                                                                                                            extern  "C"  {                                                                                        #endif                                                                                 #include   "Tolua++.h"                                                                    #ifdef  __cplusplus}                                                                      #endifextern   "C"  {#include   "lua.h" #include   "Lualib.h" #include   "Lauxlib.h"} #include   "MyClass.h" tolua_api int  tolua_myclass_open  (lua_state*  tolua_s); Int main () {    lua_state* l = lua_open ();     lual_openlibs (l);     tolua_myclass_open (l);      lual_ Dofile (l,  "Mytest.lua"); //  execute Lua script file     lua_close (L);     return 0;}

In Terminal input:

g++ main.cpp myclass.cpp-llua-ldl-ltolua++-o Test_lua

-LXX is the compilation rule for g++, which represents the library file that needs to be linked.

The result will print: Hello World
