I'm trying to find what affects gravity in modern warfare 3, so I found my Z coordinate and tried to find what accesses the address, I got the following instructions:

iw5sp.exe+22AEAD - D9 5B 08 - fstp dword ptr [ebx+08]
iw5sp.exe+A7342 - D9 5E 08 - fstp dword ptr [esi+08]
iw5sp.exe+DEEF9 - D9 5A 08 - fstp dword ptr [edx+08]
iw5sp.exe+A757C - D9 5E 08 - fstp dword ptr [esi+08]
iw5sp.exe+11E841 - D9 59 08 - fstp dword ptr [ecx+08]

I know fstp stores a float... or something like that? Can you guys explain what they do? Also, how do you find something like a max jump height value since it's constant?


iw5sp.exe+22AEAD - D9 5B 08 - fstp dword ptr [ebx+08]
^That's the one that runs when falling

[UnIoN]

you already know it, the value is getting stored at the pointed address
the value from the first floating pointer register stack st(0) is being written to [ebx+08], after that the value from st(0) is being deleted and the next values pops 1 point up

[vng21092]

but [ebx+08] doesn't hold a value, it just points to other pointers

[Zaladine]

It was actually a float value: 0x45988880 = 4881.0625

CE misinterpreted it as a pointer. It happens quite often...

[Dark Byte]

Yup it's a float, that's why CE asks you to let it GUESS the fields for you instead of asking to fill in the fields for you. (Pointer beats Float if the float value contains a part after the decimal, and pointer actually points to valid memory)

(Next ce version it KNOWS the field declaration for mono and .net apps)

hmm well I tried adding the address to my address list anyway, under value theres a Hex value, which keeps fluctuating, so I tried changing it to some random value, all it did was flash my screen to a different location for like a split second and it went back to where it was before. Don't know what to make of that...
