 Posted: Sun Apr 24, 2016 3:43 pm Post subject: Bad float precision while writing to an address |
 |
|
I'm trying to write to an address (fly address) a float value. For example, I go to CheatnEngine and I set the address' value from 0 (ground value) to 500.
Here I can see the flying effect, everything works properly ... but, when I try to set it in C++ it's like i set the flying address from 0 (ground value) to 2 (superlittle jump lol)... So I've just thought the problem was a bad float digit precision.
I've already tried and retiried the code and it works properly in other games too... Here it is :
| Quote: | | *(DWORD*)(myAddy) = (float)500; |
Why doesn't it work, or better, does that strange effect? Any tip?

*(float*)(myAddy) = 500.0f;

What ++METHOS said. I don't even know why you're asking for my help with C++. I'm not that good at it and there are many other people on this site that can help you out significantly more than I can.
Just judging based on your last few topics, you should ascertain your comprehension of C++. While you may sometimes know what to write down to make something work, it's pretty clear you don't understand what you're writing down. If you take the time to actually learn what you're doing instead of just memorizing it, you'll find that you won't make as many mistakes later on, saving you time in the long run.

Ok, now it works. Anyhow
I'm reading another pointer with this code:
| Quote: | auto baseAddress = (DWORD)::GetModuleHandle(nullptr);
auto address = *(DWORD*)(baseAddress + ANOTHERADDY);
|
why doesn't it work? With some others pointers it works...
Yes, offsets and ANOTHERADDY are correct, I've checked it 15 times.

What's the pointer path of it when it's working in CE? I can't think of anything else that's wrong besides thefourth being functionally useless.

Yeah I tried deleting that line too but still nothing...  the offsets, addys etc. are not wrong (don't worry for that, i took 3 hours to recheck everything, btw i cant screen anyway right now because im out with my sister's pc).
Any idea? I would need to try with VirtualProtect but im not sure, cuz i didnt need of it when working with all other pointers in the same game.

If this is your idea of what modulename+offset means (e.g game.exe+4abcdef0 and you assume ANOTHERADDY is 4abcdef0 ) then it's wrong.
it should then be:
| Code: |
auto baseAddress = (DWORD)::GetModuleHandle(nullptr);
auto address =baseAddress + ANOTHERADDY;
