Awesome work that will come to use for sure.

when i add in whitelist CLIENTOS_OTCLIENTV8_WINDOWS or linux or mac it still kicks me from it, it is already added in my source files

Galog333 · Nov 8, 2020

looks good. havent tested yet

APTGET · Jan 21, 2021

I tried it on my server which is based on tfs 1.2 but it doesn't seem to work. When I set: local whitelist = {CLIENTOS_WINDOWS}, in whitelist, I can still log in normally using OtclientV8. What if I resolve to "CLIENTOS_OTCLIENT_WINDOWS"

is:

"

Only clients that are on the list of allowedClients are the ones you can enter the game with him
Notes: for some strange reason OTCv8 indicates that the system is CLIENTOS_WINDOWS instead of CLIENTOS_OTCLIENT_WINDOWS on windows, so keep this in mind

Which client should I put on the list so that they can only use client 12.61?

I will answer you in your thread

The problem is when i enable g_game.enableFeature(GameExtendedOpcode) in Otclient it doesn't allow me to login using OTC.

Gover · Mar 31, 2025

Hello everyone,
@Sarah Wesker - I have a question about your sentence: "Notes: for some strange reason OTCv8 indicates that the system is CLIENTOS_WINDOWS instead of CLIENTOS_OTCLIENT_WINDOWS on windows, so keep this in mind"
Is it possible to edit this script to recognize somehow the OTClient? I'm working on a project and I would like players to use my Cipsoft Client, not the OTC (i know that it can be hacked easly propably, but maybe it will discourage people from trying OTClient - which of course have bot etc included. I will try to change RSA and other things later to secure client even more - but this script would be nice for start).
In my files (TFS 1.5 772) players can use OTClient and Cipsoft Client with this script, so using it is pointless I think, because it is not blocking anything atm.

With this test lines:

LUA:

local creatureEvent = CreatureEvent("allowedClientVersion")

function creatureEvent.onLogin(player)
    local client = player:getClient()
    local msg = string.format("Client OS: %d / Client version: %d", client.os, client.version)
    print(msg)
    player:sendTextMessage(MESSAGE_EVENT_ADVANCE, msg)
    --return table.contains({CLIENTOS_WINDOWS, CLIENTOS_LINUX}, client.os) and client.version >= 1261
    return true
end

creatureEvent:register()

I gets this output (one login try is from Cipsoft Client and second from OTClient)

Code:

Goverando has logged in.
Client OS: 2 / Client version: 772
Goverando has logged out.
Goverando has logged in.
Client OS: 2 / Client version: 772
Goverando has logged out.

Thanks in advance for help
