this is from a reply to someones pm a while ago, but also useful for everyone else

Here's the recommended way to use pointerscans (which will save your harddisk)
Find the address and add it to the list
Rightclick the addresslist and choose "generate pointermap"

restart your computer, launch the game
Find the address again and add it to a new list
Rightclick the addresslist and choose "generate pointermap" , save it as something else as before

Now you can just close the game if you like, or use the time to generate some more pointerscans for other situations. Up to you

Open the pointerscan window, tick "Use saved pointermap" and give it the smallest of the two pointermaps (scandata)
Use the dropdown menu and select the old address. (or enter it manually if you remember)

Tick "Compare results with other pointermap(s)" and give it the other address

Now you can scan as usual.


Some other tips:
If the scan takes too long, tick "Max different offsets per node" and set it to 2 or 3 and set the offset value as high as you like. (e.g 1048576) The size won't effect the results much then (unless you go really high)
It will reduce the number of results you'll get, but the results you do get are generally speaking quite good (low offset values)

Could someone explain me how the pointermap works? I don't understand, because I've seen that sometimes if I do single pointerscans instead of multiple pointermaps I get more results....
I don't know how it works btw, I just know how to use the pointerscan lol

when you use pointermaps it will do an instant rescan on every found result with the second pointermap. This is faster than a normal rescan, and decreases disksize requirement from 200GB to only 1GB or less

Thanks,
btw I'm in the case that I would like to find a pointer to an address of the ammo... the fact is that I can't debug this game because it's protected... but I can pointerscan to find it.... But it takes too much, atleast more than 5 hours for what I've seen for :
1024 offset size
level 8 pointer
and default pointerscan settings , the scan speed is about 470,500,000 paths/seconds .
I don't know what is the best I could do to avoid all this loss of time (because I can't leave the computer on for more than 5 hours) I've tried to save some pointermaps without result (maybe I'm doing something wrong)...
Are there in cheat engine some other useful tools that I could use like the pointerscan and pointermap to find a pointer just by having an address? (and without using the debugger).

And if you have more than one system you can try letting them join in on processing the data (also another reason to use secondary pointermaps so the network won't be filled with receiving useless results)

Alright correct me if this is the wrong way of doing things.

So I do exactly as you say right? I get 600 results. Now my game has CE detected so I have to disable the anti cheat every time the game starts (after it loads, it wont load with the AC disabled, Cant play online like this but I can do single player). So continuing doing scans is complicated because I can't close the game and rescan because I have to close CE every time.

What I did was this:

1: Use "What accesses this address" and find the first offset, lets say its 40. I filter the results (600 or so) by the first offset of 40.

2. I do this twice which limits the results to about 15.

3. Save the CT

4. Restart game and CE and see which ones point to the ammo still.

5. profit?

Is that the best way of going about this? Thanks in advance.

Actually NVM. I thought I had found the base address by doing this, but once I restarted my computer and restarted the game and CE they dont point to anything. Interesting. This game has me stumped.

Id be interested in seeing like a video tutorial of this if you dont mind. I'm not sure I followed exactly... but am interested in saving time/diskspace

also as for the tip to tick "Max different offsets per node" being 2 or 3... I tried setting it to 3 and leaving my offset alone, which reduced the starting amount from like 3 billion to a couple hundred thousand which was nice, but after rescanning a couple times it ended up with 0 results... so that didn't work for me. Guess Im going to have to do the insanely long way...

thing is the game is only like 100mb or so, but these pointer scans are like 30+GB, just wow.

if you use the method i described up thete your results will be a lot less.
just make sure you have seperate pointermaps with unique addresses
