C++ cheat engine (memory scanner)
Hello Jesse,
First of all, thank you for sharing your work with us.
I just wanted to know that where did you do implementation of pure virtual functions like readPage(), getChetablePages() etc.
Test the string search there.
and update docs
Not obvious what we're supposed to enter here. y/n
? 1/0
?
Would be nice to have [Y]/n
(default option).
& update docs
First, common code that goes through a chunk of memory and searches for a specific value should be refactored to be reused on windows/linux.
Second, it would be much cleaner to have a vector of bytes for the chunk of memory and std::search with a vector of bytes representing the value.
Create a test program that exits when a certain variable reaches a certain value, interact with the CheatEngine to attach to that program and change the value to the desired one.
Would probably need unit tests for the cin/cout interaction before doing that though.
just some a basic UTs setup for now:
and point to it from main README
How about a polymorphic ValueType
class? It would make the implementation of #4 easier and less distinct from the normal integer types.
Will isolate the communication with the OS and will allow to easily test the app logic through mocking.
i doing my own cheat engine scanner i do the first scan but i do not know how can i get unknown value,
i tried to get all values for ex 8 bit
value in all regoins but it take along time in cheat engine it did not take 1 second
so what is the idea of unknown value ??
And add images on the README.
Instead of only the # of memory pages
& update docs
Page where the value is doesn't fit the current criteria? What is going on here?
I think it would be cleaner if we had a class that takes care of holding the "state" of the cheat. This way, we could refactor CheatEngine to be relatively stateless:
auto matches = engine.search(value);
// ...
matches = engine.narrowDown(value, matches);
We should verify that a write
does not cross a page's boundary with the provided new value
size. We are currently okay because our values are fixed size, but it would be better to check that when the user enters a new value.
Could be interesting to add the "string" value type to search. Would read an std::string and search for the sequence of characters (excluding the null terminator).
Give build instructions for premake.
Hello Jesse,
First of all, thank you for sharing your work with us.
I am having trouble with something in helper.h file ; in 44 line that is
template
using Reader = std::function<std::istream&(std::istream&, T&)>;
while (!read(std::cin, t) || !validate(t))
I understood that t
is loaded by user input via console in Reader function, however i want to bind t with string via programmatically like t= Soccer
... How can I do that? Thank you for your help...
We should be able to search for this is a test
. The problem here is that we are asking the std::string
via std::cin >>
. We should use getline
for a String
ValueType
.
Should be done after #24 to have cleaner tests.
Happened when trying it with Minecraft. Doesn't look like it's easily reproduce-able. Finding out what the error is would be the first step... Next, it might be good to understand the conditions that lead to the crash and make a program that reproduces it.
The choice menu:
1 - byte(1)
2 - word(2)
3 - dword(4)
4 - qword(8)
5 - float(4)
6 - double(8)
is a bit confusing with numbers. Might be better with A
, B
, C
, ...
Should also update documentation.
See CheatEngine.cpp
Is it difficult to realize this idea?
& update docs
Need to properly test on windows as I fully expect to break it through refactoring without Windows CI running.
memory pag(es)
should be memory page(s)
.
& update docs
Might be the cause for some values that are not found while testing in Minecraft.
Solution: store the bytesRead
and only work with that (updating the memory block).
Many cases where we just use std::cerr and exit(1). It would be better to bubble up via custom exceptions in these cases. Let the main application take care of the error messages.
