Hi there,

I've been trying to hack FOV in games and but i seem to be having problems trying to even get the address? i know how to edit ammo/health etc and even did aspect ratio before,

Can anyone give me some tips in terms of how I should approach it? like for eg. in most FPS games, you are allowed to zoom in. How i approach it is, i search for an unknown 4 byte value and whe i zoom it, i search for a decreased value etc etc. (for 30 mins or so).

in the end, i usually am not able to get a good address though.

can anyone please give me some guidance?

thanks!

some games use integer number (4 byte) to store FOV value, some use floating point number, if you only search for 4 byte number, you don't necessarily find the right address.

using "changed value" "unchanged value" "same as first scan" help finding the address fast.
if not sure of the value type, don't use "increased value" "decreased value"

It would surely be a float, search for values between 65.0 and 90.0 then search unchanged value a lot.. hopefully you'll get down to not too many, then you can try changing the ones that end with 0 or 5 (ie 65, 70, 75, 80 etc)

Is it possible for you to tell us the name of the game? I could try and help.

the operation flashpoint 2: dragon rising.

thanks for the help guys! i'll try unchange/chagne dvalue method.

but how can you be sure it is a float? it seems a number from 60 to 90 could also be even 1 byte. but what do i know Smile anyways, i'm using search all bytes to double, but the searches are taking forever Razz

is there a way to specific only search 1 byte, 4 byte and float without the other types?
