C++ executeTalkaction 0.4 to 1.3

[roriscrave]

I need help to change this function 0.4 to 1.3
want to use like:
creature:executeTalkAction("/up")

    //doCreatureExecuteTalkAction(cid, text[, ignoreAccess = false[, channelId = CHANNEL_DEFAULT]])
    lua_register(m_luaState, "doCreatureExecuteTalkAction", LuaInterface::luaDoCreatureExecuteTalkAction);

int32_t LuaInterface::luaDoCreatureExecuteTalkAction(lua_State* L)
{
    //doCreatureExecuteTalkAction(cid, text[, ignoreAccess = false[, channelId = CHANNEL_DEFAULT]])
    uint32_t params = lua_gettop(L), channelId = CHANNEL_DEFAULT;
    if(params > 3)
        channelId = popNumber(L);

    bool ignoreAccess = false;
    if(params > 2)
        ignoreAccess = popNumber(L);

    std::string text = popString(L);
    ScriptEnviroment* env = getEnv();
    if(Creature* creature = env->getCreatureByUID(popNumber(L)))
        lua_pushboolean(L, g_talkActions->onPlayerSay(creature, channelId, text, ignoreAccess));
    else
    {
        errorEx(getError(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
    }

    return 1;
}
