Inheritance

[Christoph Schreiber <luky0711@...>]

The following code works. But I don't understand why. That drives me nuts.

int ChildClass::index(lua_State* L)
{
    const char* key = luaL_checkstring(L, 2);
    lua_getmetatable(L, 1);
    lua_getfield(L, -1, key);
    if(lua_isnil(L, -1))
    {
        luaL_getmetatable(L, Base::classId);
        lua_getfield(L, -1, key);
    return 1;
}
