Re: Help on using Luna(or Lunar)

Hope this helps.
Note that when you declare something like:
 a =Account(100);
a is already a pointer to the class Account.

I presume this is what you are looking for:
If i'm wrong, please be more specific.


 static int check( lua_State *L) {
          Account* a =checkAccount( L, 1);
          int amount =( int)luaL_checknumber( L,2 );
          a->check( amount);
          return 0; // supose Account::check doesent return any value
     }
     
static Account* checkAccount( lua_State* L, int narg) {
          luaL_checktype( L, narg, LUA_TUSERDATA);
          void* ud =luaL_checkudata( L, narg, className);
          if( ! ud)
               luaL_typerror( L, narg, className);
          return *( Wrapper**) ud;                 // unbox pointer
     }
