Change to thirdPerson and only headshot Pointer problem

Hi I have a question!

The problem is both dvars ("scr_game_onlyheadshots", "scr_thirdPerson") have the same pointer as long as you didn't make a private lobby and enable thirdPerson or only Headshot

Is there a way to change this so you can edit it online?

Okay that's confusing me right now...

I have the dvars but they all point to the same address and only change when I select thrid person in a privat lobby and changing back after the match

i'm not using any .dlls so what do you mean with G_FindDvar()?

Sorry if this question is stupid

The game has a function that allows you to find the specific dvar in one of two ways:
- Iterating through the single linked list dvar structure ( Next struct pointer is at +0x48 )
- Calculating a hash value for the dvar name and performing a lookup in a pointer table.

I'd recommend you use one of these methods as they're more reliable. Also I believe the dvar is called "cg_thirdPerson" and not "scr_thirdperson".

Yeah there is a cg_thridPerson to but i want to enable third person for everyone

and the server side third person has the same pointer as hardcore , only headshot and some other dvars and the pointer only change in privat lobbys and when i change the pointer by myselfe to the changed pointer the game just give a fuck

I posted 2 solutions above, have you tried those?

Sorry maybe im just to stupid for this because I not that used to dvars (I want to improve alot but I think no one would really put the effort into teaching me) and I didn't do a lot with hacking except my Server control and only used to java.

So could you please explain it whats the difference between
- Iterating through the single linked list dvar structure ( Next struct pointer is at +0x48 )

and my current method where I loop through every singel and look if the name is equals?

second i think is like a pattern scanner?

Sorry I know thats really Choobisch but I really want to get deeper in this

Are you finding these pointers dynamically? Aka upon game starting, you select the first dvar in the dvar array and scan through each?
You say "loop" so I assume you're doing the same thing. You also didn't state how you were finding them, just that you "had them".

Yeah, currently I scan through them every time the game is started or the hack get started because some addresses tend to change sometimes.

master131 was so kind to gave me this addresses when I asked him how he managed to change the time while he is ingame.

Code:

    Dim OFFS_DVarList As Integer = &H5AAXXXXX
    Dim OFFS_DVarList_Count As Integer = &H5AXXXXX
    Dim OFFS_DVarList_Size As Integer = &H4C

But yeah I loop through that and check the names of the dVar and return the current address.

So I get both dVar addresses i'm intressted in but both have the same pointer(value)

So when I change the value of this pointer I have hardcore, third person and only headshot.

When I creat a privat lobby and enable third person the value of the address for third person changes.

And this changes back from 31765692 to 31765704 when I start another lobby without third person and I really don't know how I can fix this problem

I'll post some info here you can use:

Code:

int __usercall G_FindDvar<eax>(char *dvarName<edi>) { int dvar; // esi@3 int result; // eax@6 InterlockedIncrement(&dword_5AA826C); while( dvarLock ) // Forget this. This is just thread safety shit j_Sleep(0); dvar = DvarHashTable[G_StringHash(dvarName)]; // G_StringHash() performs a hash on the dvar name. You can look at it to make your own then perform your own lookups. Even if the pointers change, the hash table won't. if ( dvar ) // check if dvar is valid ( Aka not a nullptr ) { while ( Q_stricmp(a1, *(char **)dvar) ) // Do an insensitive string compare with the dvar's name ( First value in struct ) against the dvar we're checking against, if they match, return that else iterate to the dvar->next ( + 0x48 ) { dvar = *(_DWORD *)(dvar + 0x48); // dvar->next ( Iterates through the dvar list ) if ( !dvar ) // Dvar has reached the end of the list goto LABEL_6; } InterlockedDecrement(&dword_5AA826C); result = dvar; } else { LABEL_6: InterlockedDecrement(&dword_5AA826C); result = 0; } return result; }

This G_FindDvar() function is located at 0x669890 on Steam iw5mp.exe

But stupid question, the pointers you're reading, are you sure you're reading them correctly?
Eg.

Code:

// I don't know VB, I'll use C# IntPtr cg_thirdPerson = IntPtr(0xDEADBEEF); int value = MemoryClass.ReadProcessMemory( handleToProc, MemoryClass.ReadProcessMemory( handleToProc, cg_thirdPerson, 4 ) + 0xC, 4 );

?

Also as a very last resort, you could just read the static offsets in the game memory for them. (Eg. cg_thirdPerson is stored somewhere in the .text section ( Aka the pointer is referenced )

Yeah I'm sure that I read them right because others are working like change gametime or change the map or the gametype

Code:

 Return IntPtr.op_Explicit(currentDvarAddress + &HC) |currentDvarAddress = Dvar name + 0xC = value

it's the only problem that the pointer only changes when I set it in a privat lobby and when I change the pointer by myself to the correct new the game don't care.

I provided you with the hash table. Those use different pointer storing. Try that.
If that doesn't work, sorry, can't help you. Only other way would be SV_ServerSendGameCommand() or whatever it was called allowing you to tell other clients what to do. ( Aka you can tell them to change their own dvars to suit your needs ).

Change to thirdPerson and only headshot Pointer problem
