Problem/bug comand "vender" server bRO

11-01/2010

I am having problems to use the command " vender" in the Kore, I type the command " vl" kore see the store and when I type " to vender + I number of loja" nothing it is made.

I used version SVN for tortoise, serverType 21 does not connect and serverType 0 connects with errors of recvpackets.txt (exactly with brought up to date them).

Already I tried to use previous versions of kore more nor arrives to connect in the map. Case somebody wants to help would be very been thankful therefore is with a project of site of search of prices stopped by this reason.

Problem still persists.

I again brought up to date the Openkore for the Tortoise, tried previous versions and nothing to enter in the store of the salesmen.

Any aid would be of great value.

- tested on some pserver and it worked,
- tested on kRO RE and this happened (+ no vend list of items):

Packet Parser: Unknown switch: 0800

this could also be the case for bRO,
if you also got this quoted message then you really should have included it since its valuable information,
and don't blame kore right away, we can only react on the changes gravity makes...

Assuming you also get this 0800 unknown switch,
we will need to implement the packet and there's 2 ways to do so:
- reverse engineer the packet's struct
- analyze the packet's data (both a recorded packet and shop's actual items list is needed)

Note the "Packet Parser", it means i actually have this packet's length in my recvpackets.txt

Accurately this error 0800 presents when it tries to have access some store.

I used Wireshark and WPE to analizar packets received by bot (visual way xkore1) and my knowledge in this area not yet and the sufficient one to correct this error.

In case that it has some tip of as to carry through the analizes of these packets would be as all community to botter of bRO been thankful. Much, thanks a lot for the support.

aha, my psychic powers didn't fail me once again (j/k)
(don't make me assume things... its dangerous)

again, this is not an error, its a warning

packet 0800 (<-packetswitch) is a dynamic length packet (obviously since a shop can have a dynamic amount of items)

if you record the packets, you should look for the 0008xxxxxxxxxxxxxxxxxxxxxxxxxxxx.... packets (remember packet 08 00 <-switch-> 00 08)
i will implement this packet, but i ask you to do the following:
1) screenshot a shop
2) record the shop's 0800 packet
3) post that here

i'll not only implement it, i'll show how it is done, so those who want can learn it, its easy

EDIT:
woops made a few mistakes, fixed now

Huhahuahahahahah

Much, thanks a lot =D

Now I will spend some liters of Coke-Cola and some hours in taken over on a contract basis mine.

Success or failure I come back to give reply.

Thx!

Edit:

I read its now edit, I will be making this now.

1 = I took the Kore to a moved away place to capture little packets.

2 = April a store with another one bot, in visual way April another one bot, with it I had access the store and I captured packets below.

hmm i thought it was clear, but i'll clarify it now:

1) screenshot a shop -> i need to know what items are in the shop (it needs to have preferably more than 1 item) -> a screenshot will do, i can look up the item ID's myself
2) record the shop's 0800 packet -> and post the text here -> a picture of text is unorthodox, i don't want to type it all again

also, the packet recording must happen on a character that is visiting the shop
also, the packet recording you provided seems to have the TCP header etc... thats not of interest to us

[Castiel]

It forgives the delay in the reply, strong rain internert is trash.

ID's items in shop

Code: Select all

4321#Carta Poltergeist#
607#Fruto_de_Yggdrasil#
7213#Almofada_de_Alfinetes#
7217#Carretel#
7190#Casco_de_Inseto#
610#Folha_de_Yggdrasil#
523#Água_Benta#
2501#Capuz#

Archive annexed with the packages that asked for.

yea, thats exactly what i asked for, but i'm going to sleep in a few mins so i couldn't wait, and i've already found it (well kinda)

analized packet:

Code: Select all

0008									packetswitch
4e00									packetlength

21651d00								venderID
dc000000								unknown field (new)

00879303								price
0100									amount
0200									index
04									type
fe14									nameID
01									identified
00									broken
00									upgrade
0000000000000000						cards

more items....

note, all bytes are in little endian notation:
fe14 (LE hex) => 14fe (BE hex) => 5374 (decimal)
00879303 (LE hex) => 03938700 (BE hex) => 60000000 (decimal)

the packet stuct header:

Code: Select all

v2 V x4

(x4 is still an unknown field)
the repeating struct in the packet struct:

Code: Select all

V v2 C v C3 a8

but don't go patching anything yet, a proper fix will be provided soon enough

btw,

carta poltergeist = whisper?
carta esqueleto prisioneiro = skeleton prisoner?

lol

[Castiel]

Then what this making to occur the problem is these unknown fields?

Something more than I can post to facilitate the support?


Edit:

Vi now its edit. Then I am I wait in it (as well as the community to botter serving bRO) of this resolution

He seems repetitive but… Thanks a lot!
