Cheat Engine

[crapped]

Well im absolutely curious how to do that in delphi

well i have a trainer with threading timer to read the value

well everytime i start game it display negative exponent( i think thats the name) 1,74356281163922E-39 before load the savegame

whats the exact method to display '?????' if pointer point to wrong address ?

ive tried reading cheat engine source but i dunno where its located since CE have a huge and pretty complex source.

simple: If any of the readprocessmemory calls returns false just return ????????

IsBadReadPtr wont work unless you are injected into the process. The address passed to IsBadReadPtr is checked against the current processes memory, not the one you are targeting.

ReadProcessMemory returns a boolean, just check if it fails. If it doesn't then you can either assume the pointer is valid, or you have read invalid data. If you can assume the data is supposed to be a specific value, or at least within a specific range you can double check using that as well.

Such as if the memory you are reading is a string, you can check if the first character is valid and not null. Or if you are reading an integer, if the value can only be within a specific range you can check that as well and so on.

Thank you wiccan for giving me more knowledge!

thats why im confused because theres no bridge using IsBadReadPTR to read from target processes.

i would gladly comeback to ask or giving some contribution if i could
since this is my second time asking ppl when im stuck (except to google)
and the answer is pretty fast and helpfull..

Thanks before.
