No recoil/ laser makes game crash

[ryankinzz]

So im new to making things for mw3 and I watched a few tuts and I cant figure out how to get certain things working like no recoil laser and fov
here is the code that im using. Im trying to get laser working here.

byte[] L = { 0x0 };
        private void button3_Click(object sender, EventArgs e)
        {
            if (Process_Handle("iw5mp"))
                WriteInteger(0x43AC97, 1);
        }

Can someone please help me thanks

well then you should learn a bit more.. for Lasers you have to write a BYTE, 0, to 0x43AC97. You're writing an INTEGER... that will obviously crash your game cause instead of overwriting one byte you're overwriting 4 (Integer = 4 bytes)...

byte[] b = { 0 };
WriteBytes(0x43AC97, b);

Yeah I know I cant find any tuts I only found were Jorndel's and i dont think he has one can you tell me how to get fov working becuase when i type 80 it zooms in reallly far!

float FoV = 65;
WriteBytes(0xAddy, new byte[] { (byte)FoV } );

We just set a float value, then we write that as a byte list.
We only apply 1 item to our byte list.

You can now use the float on other stuff as well.
Like an increase/decrease.

So I do this

        float Fov = 65;
        private void button8_Click(object sender, EventArgs e)
        {
            if (Process_Handle("iw5mp"))
            WriteBytes(0x5ABD5AC, new byte[] { (byte)Fov });

because that didnt work :/ I know I sound like a noob right now

You do know that 65 is the default?

[ryankinzz]

Yeah but when I changed it to 80 nothing happens

[Jorndel]

Check the address with Cheat Engine.
Sometimes I experience that it don't match.

any updates with your progress? I know C++ a bit and need no recoil too so I'd be interested in knowing how to do it, thanks!

C++ Code:

*(BYTE*)0x004D14B7 = 0x0; //Laser -> Write NULL(Aka 0) to Laser Address
*(int*)0x0054F8F9 = 0x90909090; //Write four NOP bytes to the No Recoil address
*(BYTE*)0x0054F8FD = 0x90; //Write the last byte to the No Recoil address
*(float*)0x59C0724 = (float)90; //Changes FoV to 90.0f

These are for 1.4.382
Sorry if you didn't want c++ code. Didn't exactly read the above post. Just saw C++

Why write a int then a byte for the no recoil? :S Just writes 5 Nops and you're ok (BYTE Nops[5] ={ 0x90, 0x90, 0x90, 0x90, 0x90 }; )

It's the difference of 2 lines vs ...more than 4....plus way shorter

How can that be shorter =O

And, OP, if you want to find the new offsets for it, take a look at this tutorial.. https://www.mpgh.net/forum/279-call-d...d-offsets.html It's for COD4, but the same logic still works with MW3.

(Using your general method)

unsigned long *NoRecoilAddress = (unsigned long*)0x0054F8F9;
unsigned char noRecoilPatch[5] = {0x90, 0x90, 0x90, 0x90, 0x90};
unsigned long *LaserAddress = (unsigned long*)0x004D14B7;
unsigned char laserPatch[1] = {0x00};
unsigned long *FoVAddress = (unsigned long*)0x59C0724;
unsigned char fovPatch[1] = {90};
memcpy((void*)NoRecoilAddress, (void*)noRecoilPatch, sizeof(noReoilPatch));
memcpy((void*)LaserAddress, (void*)laserPatch, sizeof(laserPatch));
memcpy((void*)FoVAddress, (void*)fovPatch, sizeof(fovPatch));

(Using my method)

*(BYTE*)0x004D14B7 = 0x0;
*(int*)0x0054F8F9 = 0x90909090;
*(BYTE*)0x0054F8FD = 0x90;
*(float*)0x59C0724 = 90.0f;

Difference: 9 long lines vs 4 short lines. #Tr0L
I win.

BYTE Nops[5] = { 0x90, 0x90, 0x90, 0x90, 0x90};
(BYTE*)0x0054F8F9 = Nops;
