Call of Duty 4 Third Person

Introduction

Hey all, this is a simple third person hack for call of duty 4 1.4... It uses strifes console function and some more simple stuff. It looks cool for screen shots etc.

I found, that with strifes function, you can use cheat protected cvar/dvar's pretty easily.

For example:

Cg_thirdPerson is cheat protected, and when you try and enable it in the console it will give you the message 'this variable is cheat protected'... So what we do is, disable the cheat protection; send the command; re-enable the protection:

Code:: if(bThirdPerson)// Enable Third Person
{
WriteProcessMemory(hand, (void*)(0x0056B016), &CP, 2, 0); <-- Disable cheat cvar/dvar check
ConPrint(0, "Third Person Enabled!");
SendCommandToConsole("cg_thirdPerson 1") ; <-- Send Cheat command to console
WriteProcessMemory(hand, (void*)(0x0056B016), &CPOrig, 2, 0); <-- Re enable cheat cvar/dvar check :))
bThirdPerson=false;
}

This should stop you form being kicked for memory corruption if you do it at the right time. Any who, you should be able to do this for any of the cvar/dvars: such as: cg_drawShellshock, player_sprintCameraBob, r_fog and other small tweaks.

Source is coded in Visual Studio 2008. Full Project & Compiled module attached (includes Winject). Numpad 1: Enable, Numpad 2: Disable (may have to use numlock).

Code:
main.cpp:

Code:: // Call of duty 4 1.4 - Simple Third Person
// Credits: Quicktime, Strife, Runningbon.
//Includes
#include <windows.h>

// prototype (console)
typedef void (*g_ConPrint)(int Index, const char *fmt);
g_ConPrint trap_ConPrint = (g_ConPrint)0x004FCAB0; // Call of duty 4 1.4 offset

//Globals
bool bThirdPerson = false;
bool bThirdPersonDisable = false;
HANDLE hand = GetCurrentProcess();

//Cheat Protected
BYTE CP[] = {0xEB, 0x29}; //0056B016 EB 29 JMP SHORT iw3mp.0056B041
BYTE CPOrig[] = {0x75, 0x29}; //0056B016 75 29 JNZ SHORT iw3mp.0056B041

// Credit to Strife: Console Function
void SendCommandToConsole(char command[])
{
__asm
{
push command
push 0
push 0
mov esi, 0x004F99A0
call esi
add esp, 0x0C
}
}

// Printing to console function (Quicktime/Runningbon)
void ConPrint(int Index, const char *fmt)
{
(trap_ConPrint)(Index, fmt);
}

DWORD WINAPI SendCommands(LPVOID)
{
for(;; Sleep(500))
{
if(GetAsyncKeyState(VK_NUMPAD1)) // Enable Third Person
{
bThirdPerson=true;
}

if(bThirdPerson)// Enable Third Person
{
WriteProcessMemory(hand, (void*)(0x0056B016), &CP, 2, 0);
ConPrint(0, "Third Person Enabled!");
SendCommandToConsole("cg_thirdPerson 1") ;
WriteProcessMemory(hand, (void*)(0x0056B016), &CPOrig, 2, 0);
bThirdPerson=false;
}

if(GetAsyncKeyState(VK_NUMPAD2)) // Disable Third Person
{
bThirdPersonDisable=true;
}

if(bThirdPersonDisable) // Disable Thid Person
{
WriteProcessMemory(hand, (void*)(0x0056B016), &CP, 2, 0);
ConPrint(0, "Third Person Disabled!");
SendCommandToConsole("cg_thirdPerson 0") ;
WriteProcessMemory(hand, (void*)(0x0056B016), &CPOrig, 2, 0);
bThirdPersonDisable=false;
}

}

return 1;
}

BOOL APIENTRY DllMain(HMODULE hModule,DWORD AreWeInside,LPVOID lpReserved)
{

if(AreWeInside == true)
{

ConPrint(0, "Injected OK!!");
Beep(150,150);
CreateThread(NULL, NULL,SendCommands, NULL, NULL, NULL);

}

return 1;
