Hello guys,

I have a custom protocol "312" to be added in OTClient V8 and I have edited:

Lua:
""protocollogin.lua""

function ProtocolLogin:sendLoginPacket()
  local msg = OutputMessage.create()
  msg:addU8(ClientOpcodes.ClientEnterAccount)
  msg:addU16(g_game.getOs())
  if g_game.getCustomProtocolVersion() > 0 then
    msg:addU16(312)  -- msg:addU16(g_game.getCustomProtocolVersion())
  else
    msg:addU16(g_game.getProtocolVersion())
  end

Done this i can login into CHARACTER LIST.

charct.PNG

but when i selected to login with the character, i get the same error:

loginerror.jpg

Here is my "protocollogin.lua" and "entergame.lua"



Can you help me, please?

Thanks very much!

Set it in entergame.lua:
Code:
g_game.setCustomProtocolVersion(312)
There are few occurrences of setCustomProtocolVersion . Debug which is used in your case or just edit them all.

I have compiled the server source, changing:

Lua:
#define CLIENT_VERSION_MIN 312
#define CLIENT_VERSION_MAX 312
#define CLIENT_VERSION_STRING "Your client is outdated, please visit http://www.psoul.net and download the latest client."

Into:

Lua:
#define CLIENT_VERSION_MIN 854
#define CLIENT_VERSION_MAX 854
#define CLIENT_VERSION_STRING "Your client is outdated, please visit http://www.psoul.net and download the latest client."

in "resources.h" and it works, but when i join the server i get the client like this:

1624046109281.png

and the client crashes.

my .spr and .dat is:

Did you edit all g_game.setCustomProtocolVersion in that file or just one?
What is official client for that server? There can be custom client version (312) and other anti-bot features, like added one extra byte to game protocol that detects custom client (official server client). In this case, you cannot use OTCv8 (no sources - cannot add extra byte).
When I prepared custom client for Kasteria X years ago, I added 5 different client detection features, so hackers had to waste a lot of time to connect with other client. They fixed one problem, there appeared other.

That's common 'anti bot trick' with extra bytes.
like added one extra byte to game protocol that detects custom client
Server send packets with extra bytes, it's not compatible with any tibia protocol (like 8.1, 8.6 etc.). So now you need to check what changes are in server protocol (a loooot of work) and implement same changes in client :(

You mean check all the server sources files with tag "protocol" ?

I mean you need to know every byte of X.XX protocol and find what is changed in server sources. It can take hoooours. Someone implemented antibot system - allow only official client - and you need to use his client. Trying to use other client may take hooours.

Got you, no problem about the time, maybe are you talking about this one (packet):

Got you, no problem about the time, maybe are you talking about this one (packet):

Lua:
ProtocolGame parse message exception (21 bytes, 12 unread, last opcode is 0xff (255), prev opcode is 0xffffffff (-1), proto: 854): unhandled opcode 255
14 00 24 08 e6 3f 0d 00
ff 01 90 29 04 fa 2e eb 2d c2 2d ef 2d
1. Only first error "parse message exception" after login matters. Rest can be result of not reading first invalid packet.
2. Errors like that may occure because of 2 reasons:
  • extra bytes added to protocol by server author (to block custom clients = bots)
  • not compatible .otb (server) <-> .dat (client)

Maybe you can teach me an exemple, how can i find "byte of X.XX protocol (Im sry, but i dont get this term X.XX)" in source files.
I mean 8.10 or 8.60. Client expects some official tibia protocol. Server uses some tibia protocol with changes. To find changes, you need some other engine with X.XX protocol (ex. 8.60) to compare what bytes should be there and what bytes you get from server.

I have compiled the server source, changing:

Lua:
#define CLIENT_VERSION_MIN 312
#define CLIENT_VERSION_MAX 312
#define CLIENT_VERSION_STRING "Your client is outdated, please visit http://www.psoul.net and download the latest client."

Into:

Lua:
#define CLIENT_VERSION_MIN 854
#define CLIENT_VERSION_MAX 854
#define CLIENT_VERSION_STRING "Your client is outdated, please visit http://www.psoul.net and download the latest client."

in "resources.h" and it works, but when i join the server i get the client like this:

and the client crashes.

Thx, now i understand.

Do you have information (tutorial) on how can i learn to do these comparisons so that I can modify the client?

You can not compile it, cuz it do not have open sources as you can see here: OTCv8/otclientv8 (https://github.com/OTCv8/otclientv8)
