How to find GAMEPROTO_CS_CLIENTFIRE

Hello everyone, Could some one help me finding the CS_client fire func , I managed to use x ref to get the push string but i realy don't know how to get the rigt addy of the func.

and what are the arguments does this function take or how does it work or what's calling this function so i can bypass 22-11 client error .

I managed to hook the 28-5 and 28-3 func but i need to find the GAMEPROTO_CS_CLIENT fire in order to bypass 22-11 .

IM using x32 bit version of a private crossfire server.

use IDA and search it as Names Window, if it doesn't show use class informer

Okay i found the function and I reached this snippet of code , could you tell me what call here or what line that check for node change so i can bypass

I uploaded the snippet of code.

hmm why not try hook it and reverse it?

AFAIK back in my days, I used to bypass clientfire by intercepting the outgoing packets hehe it's easier that way, just make the packets look normal

Do you have discord ? I stuck with this error code

I tried to catch the packets sent but nothing found

On a second thought, it probably might be harder because you need to format them packet bytes and identify which is which. I guess i just got lucky since someone gave me the byte format/structure. And then i noticed that there's something incrementing on the packet while firing so i messed with the increment and noticed that i'm not hitting client error.

It might be a lil bit slower because you need to modify the whole packet before sending it compared to actually finding the function that causes it.
I recommend that you should just find the function instead, it's optimal and nicer and you already have a hint above about it's signature.

Did you get past it?

still stuck on the function
i figured that the function do three checks a check on model node damage
and a check if ai but I don't know is there other checks

yes I'm stuck like you, it's hard to search
