In lua I assume your C++ method is bound to something like XX:GetList() :

 

-- Just use table constructor to put all your elements in a table

local elements = { XX:GetList() }

-- Iterate on it to access your elements

for key,val = ipairs(elements) do

    local i = val

    print(i)

end

Hello,I meet a question:

In C++ Use luaWrapper:

int XX::GetList(lua_State* L)

{

    int nCount(0);

    for( int i = 1; i < MAX_NUM; ++i)

    {

        if(m_array[i] == TRUE)

        {

            lua_pushnumber(L, i)

            ++nCount;

        }

    }

    return nCount;

}

In lua, How Can I Get This List Elements?

 

thank!

主题： no calling environment

 

 

After  recently  upgrading  to  Lua  v5.1.1,    I  am  now  getting  an  error  when  

trying  to  call  luaopen_io    (previously  known  as    lua_iolibopen):

 

luaopen_io- >lua_replace- >lua_G_runerror

 

lapi.c  line  203:  

 

/*  explicit  test  for  incompatible  code  */

if  (...)

       luaG_runerror(L,  "no  calling  environment")

 

Can  someone  tell  me  why  one  would  get  this  error?    I'm  not  messing  with  

environments  (not  on  purpose,  anyway).
