C++ Npc trade

[Blade33711]

Hi everyone! I'm using tfs 0.4
I need a help. How to make the function also work with npc?

int32_t LuaInterface::luaDoStartTrade(lua_State* L)
{
    ScriptEnviroment* env = getEnv();

    Item* item = env->getItemByUID(popNumber(L));
    if(!item)
    {
        errorEx(getError(LUA_ERROR_ITEM_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }

    Player* target = env->getPlayerByUID(popNumber(L));
    Player* player = env->getPlayerByUID(popNumber(L));
    if(!player || !target)
    {
        errorEx(getError(LUA_ERROR_PLAYER_NOT_FOUND));
        lua_pushboolean(L, false);
        return 1;
    }


    if(g_game.internalStartTrade(player, target, item))
    {
        lua_pushboolean(L, true);
        return 1;
    }
    return 1;
}

did you want to trade an ID item xxxx, and the NPC trade you in another ID item xxxx?

Yes, but I want to do it through the window like on screen.
