So, i don't need to modify anything else beside the Bytes values in c++ code ?

I get this 15 bytes long : BYTE Bytes[15] = { 0xC7,0x87,0x34,0x03,0x00,0x00,0x02,0x00,0x00,0x00,0xE8,0x25,0xDA,0x0A,0x00 };....
Changed this : mov [edi+00000334],eax to this : mov [edi+00000334],00000002, then took the code , write in the program....
But is crashing ofc Very Happy
Tried with more addresses and less...nothing worked.

Changes should me made in here to ?
Code:
int newValue = MyMemory + 4;
   WriteProcessMemory (hProc, (void*)MyMemory, &newValue, sizeof(newValue), NULL);
    newValue = 0x25FF;
   WriteProcessMemory (hProc, (void*)atkBase, &newValue, 2, NULL);
    newValue = MyMemory;
   WriteProcessMemory (hProc, (void*)(atkBase + 2), &newValue, 4, NULL);


edit:
Btw, i told you before, if i try to change the original value there and put anything like jmp XXXXXXXX or jmp dword [XXXXXXXX], the game is crashing instantly.

So my first step is to copy original values on notepad, all opcodes+addresses, then go to Tools/Allocate Memory, and here i put this on the first free value : mov [edi+00000334],eax...then modify it for my needs.
Is this the right way?

Things are getting more complicated Smile
All is working fine now and i added few new values for what i need,.
Now if i want to set a value before the code is written to memory, like cin >> value;...well it's kind of hard now with hex values and my value being inside an array Sad :

BYTE byt[16] = { 0xC7,0x80,0xEA,0x04,0x00,0x00,0x14,0x05,0x00,0x00,0x8B,0xE5,0x5D,0xC2,0x08,0x00 };

The yellow value i need to modify it before the "WriteProcessMemory" command.

Any idea how to do that?
Thank you,

just add this to your code cave:

Code:
mov ecx,00000002


bytes are: B9 02 00 00 00

I was looking for other easy method to access that register without codecave, i mean without so many "WriteProcessMemory".
Something with _asm.

Other weird thing is that the code is activating only after i switch my weapon in game or use something that access the address.
The problem is ...i am using 2 weapons, and one of them uses low values, around 900, and when i switch on that ...i still have the higher value from the first weapon, 1200.
And my attack is very slow Smile)


Big Edit :

Huh, i'm stuck again...i thought i can't make it alone by now...i was wrong Smile
Can you please explain/comment what your function does exactly.... because i read this forum 1000 times and still getting stuck. Look at my code now, it's on 64bit, worked fine with only one address, but with second one it's crashes. I know i fixed the first one by luck now...Neutral

Code:
   DWORD atkBase = (DWORD)BaseAddress + 0x22E2D8; int atkSpd; 
   DWORD wepBase = (DWORD)BaseAddress + 0x1C4AB7; int wepSpd;

   cout << "wepSpd:" << endl;   cin >> wepSpd;
   cout << "atkSpd:" << endl;   cin >> atkSpd;
   cout << "Press HOME to start the cheat" << endl;
   
   BYTE wepByt[10] = { 0xC7,0x87,0x64,0x03,0x00,0x00,0x00,0x00,0x00,0x00 };

   BYTE atkByt[30] = { 0xC7,0x83,0x1A,0x05,0x00,0x00,0x00,0x00,0x00,0x00,0x48,0x8B,0x74,0x24,0x40,
                       0x48,0x8B,0x6C,0x24,0x48,0x48,0x8B,0x5C,0x24,0x50,0x48,0x83,0xC4,0x58,0xC3 };
   
   int tempW = wepSpd; for(int c=6; c<10; ++c) { wepByt[c] = (tempW & 0xFF); tempW = tempW >> 8; }
   int tempA = atkSpd; for(int c=6; c<10; ++c) { atkByt[c] = (tempA & 0xFF); tempA = tempA >> 8; } // Write 8 bytes starting with 6th position
   
   DWORD vMemory = (DWORD)VirtualAllocEx (hProc, NULL, 0x1000, MEM_COMMIT|MEM_RESERVE, 0x40); // This allocates Virtual Memory

   while (1) { Sleep (1);   if (GetAsyncKeyState(VK_HOME) & 1) {

      //Not Working Side
        WriteProcessMemory (hProc, (void*)(vMemory+ 4), &wepByt, 10, NULL);
        newValue = vMemory+ 4;   WriteProcessMemory (hProc, (void*)vMemory, &newValue, sizeof(newValue), NULL);
        newValue = 0x25FF; WriteProcessMemory (hProc, (void*)wepBase, &newValue, 2, NULL);
        newValue = vMemory;   WriteProcessMemory (hProc, (void*)(wepBase+ 2), &newValue, 4, NULL);


      //Working Side ...this is the first function that is working alone.
        WriteProcessMemory (hProc, (void*)(vMemory+ 14), &atkByt, 30, NULL); // This modifies 30 bytes at Virtual Memory+ 14 ?! ([color=blue]can't uderstand this[/color]...)
        newValue = vMemory+ 14;   WriteProcessMemory (hProc, (void*)vMemory, &newValue, sizeof(newValue), NULL); // ([color=blue]can't uderstand this[/color]...)

        newValue = 0x2524FF; WriteProcessMemory (hProc, (void*)atkBase, &newValue, 3, NULL); // This modifies 3 bytes on atkBase ?! ([color=blue]can't uderstand this[/color]...)
        newValue = vMemory;   WriteProcessMemory (hProc, (void*)(atkBase+ 3), &newValue, 4, NULL); // This modifies 4 bytes at atkBase+ 2 ?! ([color=blue]can't uderstand this[/color]...)

      cout << "Cheat:  ON" << endl; }

   else { if (GetAsyncKeyState(VK_END) & 1) {.........


The Not Working Side is the new addition...i will post the picture of it.

Thank you,
