        int32_t cid = popNumber(L);
       
        lua_State* state = interface.getState();
        lua_getglobal(state, "War");
        lua_getfield(state, -1, "morte");
        lua_pushnumber(state, cid);
        lua_pushnumber(state, target);

        lua_call(state, 2, 0);       
    }
   
    return 1;
}

How do i declare it friend function? If someone could help me please because im not so good in C++

NVM I found fix, i made public
virtual LuaInterface& getInterface() {return m_interface;}
LuaInterface m_interface;
on talkaction.h
