System ma usunięte wszystkie dotychczasowe błędy typu: klonowanie przedmiotów. Działa bez błędnie na tfs: 0.3.4 , 0.3.5 , 0.3.6 !

Skrypt działa na zasadzie: gracz x wystawia przedmiot na aukcje za 10k musi wyjść wiec wychodzi z gry. Gracz y zauważa na stronie atrakcyjną oferte i kupuje przedmiot na aukcji.Graczowi y zostaje zabrane 10k a dostaje przedmiot który kupił a gracz x otrzymuje 10k które ma w plecaku.

No to zaczynamy!

**Część SQL**

Pamiętamy też aby dodać to do index.php 

<file php>
   case "auctionsystem";

          include("auctionsystem.php");

Oraz do naszego layouta!( tutaj nie będę podwał ponieważ każdy może mieć inny sposób dodawania.)

** Część LUA **

Wchodzimy do katalogu /data/talkactions/talkactions.xml tam dodajemy linijkę:

<file xml>
<talkaction words="!offer" event="script" value="auctionsystem.lua"/>
</file>

Nastepnie przechodzimy do katalogu /data/talkactions/scripts/ i tam tworzymy plik auctionsystem.lua oraz dodajemy do niego:
