Re: Down-casting a C object to a Lua object

[Colm Sloan <colmsloan@...>]

No, sorry. You're right. I'm using LuaBind. I'm amazed you figured that out from my post. Here's my most recent attempt:

void Person::Setup( void )

{

const char* className = m_LuaClassName;//"Soldier";

// trying to make a function on the fly to give me an empty object of specified Lua type

char functionCode[ 384 ];

strcpy( functionCode, "function GetLuaVersion()\n" );

// assemble the line "return Class()"

char returnClassLine[ 256 ];

strcpy( returnClassLine, "return " );

strcat( returnClassLine, className );

strcat( returnClassLine, "()\n" );

strcat( functionCode, returnClassLine );

strcat( functionCode, "end\n" );

luaL_dostring(

L,

functionCode

);

//get the new 'Soldier' object

m_LuaClassObject = luabind::call_function<luabind::object>( GetLuaHandle()->GetLua(), "GetLuaVersion" );

//several attempts at moving the data from this (Person) into the Lua Soldier on the following lines

luabind::call_member<void>( m_LuaClassObject, "Setup" );

}
