    Getting parameter

    How would i be able to get the position?

    Code:
    0050F250  |. 6A 40          PUSH 40
0050F252  |. 68 98975C00    PUSH GunzOld.005C9798                    ;  ASCII "Spawn"
0050F257  |. 68 8C975C00    PUSH GunzOld.005C978C                    ;  ASCII "Peer.Spawn"

    This looks like the output of a disassembler...

    The reference to "Position" is as an ASCII string. So this code may in fact have nothing to do with the actual value of the Position, whatever that is.

    Looks like a function call to "GunzOld.004EDFC0" with parameters (6, "Position"). Maybe this is a status-printing function, or logging function, or some such.

    And what does this have to do with C++?

    He's supposedly writing an anticheat for a game called Gunz.exe. I am suspicious of people that are supposed to be anticheat authors that don't know what they are doing.

    Check out treshacks

    If you truly want to see how it's done, and done successfully, download the atx_mod. Source code (assembly) and basic tut. Granted, there isn't many Trespasser fans around these days, though you can apply similar principles to other game executables.
