Tutorial (C++) How To Add in MW2/MW3 Structs

[Venox]

//Some structs  for mw3 but you can use this mw2(Update the Offsets )


struct Vector3;

    }

    {
        DbgPrint("%s addr: %X v1: %f v2: %f v3: %f\n", Text, v, v[0], v[1], v[2]);
    }
};

    VOID SetOrigin(Vector3 NewOrigin)

//Some functions


VOID (__cdecl *ClientCommand)(INT ClientNumber) = (VOID (__cdecl *)(INT))0x82239C80;
BOOL (__cdecl *Dvar_GetBool)(PCHAR Dvar) = (BOOL (__cdecl *)(PCHAR))0x8232E200;

//Monitor connection/disconnection damage and death + more
//Code (Text):
UINT16 Scr_ExecEntThread(gentity_s *gentity, INT Handle, UINT32 ParameterCount)
{
    //DbgPrint("Scr_ExecEntThread - gentity[%X] Handle[%X] ParameterCount[%X]\n", gentity, Handle, ParameterCount);

    switch(Handle)
    {

        break;
    case 0x103814:

//Then add this
//Code (Text):
DetourFunction((PDWORD)0x8226AEE8, (DWORD)Scr_ExecEntThread);

For a modded lobby
Code (Text):
    *(UINT16*)(0x8222E59C + 0x02) = 450; // G_Speed
    *(FLOAT*)0x82001D68 = 999; // Super Jump
    *(FLOAT*)0x82000C04 = 9999; // No Fall
    *(INT*)0x820F63E4 = 0x7D495378; // Unlimited Ammo - mr r9, r10
    *(INT*)0x820F46DC = 0x39600000; // Full Auto Guns - li r11, 0
    *(INT*)0x82233A7C = 0x60000000; // Disable PlayerCmd_FreezeControls

Real Godmode (no blood)
Code (Text):
gentity(Client)->playerState->MaxHealth = 9999;
gentity(Client)->Health = 9999;



//----------------------------------------------------------------------

*(int*)(getEntity(clientIndex) + 0x184) = 1; -> god mode On
*(int*)(getEntity(clientIndex) + 0x184) = 0; -> god mode Off
*(int*)(getEntity(clientIndex) + 0x184) = 3; -> no Knockback but no godMode
*(int*)(getEntity(clientIndex) + 0x184) = 2; -> demigod (i think)
