Cheat Engine

So... I ended up not being able to find out how to find the static address of memory in a game.
So I ended up making a Console app which will search for each value separately, then respectively change them as I please.

To loop through each variable, I decided to make a loop in which the Hex value to scan for starts at 0x00000000 and ends at 0xFFFFFFFF.
This works. However, Incredibly slowely.
Since there are over thousands of variables from 0x00000000 to 0xFFFFFFFF, it takes thousands of frames to search each and every variable.

So I'm trying something like Cheat Engine, Where you search a number; And it pops up. Only difference is, it auto-changes the variable.
So if I were to want to change any variable of 15 to 0, It would search through all addresses for the number "15" and changes it to "0".
This currently works, but at a SUPER SLOW pase... Which I want to speed up.

In overall terms, I want it to scan as fast (Or faster) as Cheat Engine, but auto-change the variables I want so I don't have to.

How can I speed it up like this???

Thanks!

You can do multiple threads, each thread scans a region of the memory (you divide the regions as you like).

I found some usefull information on threading. But even with this,
How do I set it up to speed this search process, anyways???
I'm wanting to find every value from 0x00000000 to 0xFFFFFFFF which could take several THOUSANDS of frames. Resulting in actually getting from 0x00000000 to 0xFFFFFFFF within hours.

How does cheat engine find these variables so quickly??
I can't understand the process of how that works.

I made each frame add 0x00000001 to 0x00000000, and each frame; It reads the process for the address's value. Again, this works, but would take hours to fully finish.
I just don't understand how Cheat Engine does this.

I'm trying to do this for this reason;
Making a program to search for any 'double' value with 15, and make it 0 automatically on startup. Cheat Engine does not do that, and this would be very simple for me to do rather than going through many settings to set up.

I tried looking it up on google. But found no help.

Thank you so much for that awesome concept. Smile

So to do this "the lazy way" (only because I'm not familiar with VirtualQuery), I'd need to search doubles for...
1. a multiple of 4
2. If no readable memory found, skip 1000 (no readable memory on 0x00000250, go to 0x00001250)
3. Start at 1000, end at 7FFFFFFF

Thank you so much. Smile

I have yet to test this out, I will post my results!!

It's a ton faster than it was before. I didn't realize it was every thousandth and not SKIP a thousand Razz

I fixed that.

My same issue is occurring; It's still a lot slower than I'd like it to be.
Am I asking too much here? Surprised

I'm trying different combinations.
It searches for addresses with a multiplicative of 4.
Once it's found that; If it is not readable, it goes to the nearest thousandth.
It then searches for what is a variable of "15" and changes it to "0".

The current process for this to change all addresses is, well...
Around 3 minutes probably? (There are over 300 results for variables of 15)

Never read less than 4096 bytes at a time with readprocessmemory
If possible, combine regions first so you have the biggest possible chunk
