Re: Signature Request Thread

Hi.
I'm searching the sig and the mask for CBasePlayer::FireBullets currently.

Thanks,

What game?

@CrimsonGT: I couldn't find that sig lol, it's one of those ones that are "unsiggable" unless you tried patchdiff'ing between hl2dm and tf2 :/

Re: Signature Request Thread

Hi.
For Counterstrike: Source.

Thanks,

Re: Signature Request Thread

Can't you just hook that function?

Virtual offset 101...

Re: Signature Request Thread

How I should do this? I can't lay a hook about all player instances, that not possible. For that, I need the sig and mask, do I!?

Re: Signature Request Thread

You can hook when a player connects, then unhook when they leave. I do this for FireBullets, TraceAttack...

Works fine.

Re: Signature Request Thread

Nice!
Very cool idea, and yep, it works.
Thank you so much :)

Thanks,

haha damnit, ah well. I was hoping :P

Re: Signature Request Thread

Anyone have any ideas on how I could go about finding CTFGameStats::IncrementStat(CTFPlayer *, TFStatType_t, int) ???

I think this is another unsiggable function because each time I get to a function that references it, I get:

Code:

  v11 = 684 * (*(int (__stdcall **)(_DWORD))(*(_DWORD *)dword_1047E1B8 + 72))(*(_DWORD *)(v3 + 24));

  ++*(_DWORD *)(v11 + v4 + 156);

  ++*(_DWORD *)(v11 + v4 + 248);

  ++*(_DWORD *)(v11 + v4 + 340);

  return v11 + v4 + 148;

It doesn't look like it's being directly called :S

What you can probably do is use this:

Code:

\x2A\x2A\x2A\x2A\x2A\x83\xB8\x18\x03\x00\x00\x04\x53\x2A\x2A\x2A\x2A\x56\x57\x8B\xF1\xBF\x01\x00\x00\x00\x75\x39

Which is the (untested) signature for CTFGameStats_Event_PlayerFiredWeapon which calls CTFGameStats::IncrementStats. From there....

Code:

void* pfnIncStats = NULL;

void* pfnFireWeaponFunc = gSigMngr.findsignature(laddr, the_sig_above, length_of_above_sig);



typedef void (*IncrementStatsFunc)( void* /* this */, int /* TFStat Type */, int /* Some random integer :S */);

IncrementStatsFunc pStatsFunc;



//Not sure if this is right. Very low level and only for windows :/

memcpy( pfnIncStats, ((char *)pfnFireWeaponFunc + 0x65), sizeof(char *) );



//Call the function :D

//....

This should rip the pointer to CTFGameStats__IncStats directly from eax (assuming I did the hex right :P)

Let me know if it works for you.
