Yes, it's easy, but only in the CE tutorial.
But when you try even in a simple game, when the possible addresses found candidate to be pointers are tons and ton, what can we do?
It's impossible try one to one...
And also the scanpointer option, is really hard that works...
In a game we do NOT have got somethingh like a button "change pointer", instead we have to restart the level, or even worse we have to reload the game again otherways the pointer does not change.
I have read both on this forum and also googling otherways, but I'm unable in understandanding what can we do when the results are so excessive.
May we "poor newbie" receive further help about?

Thanks to all.

Psst.
The pointer scanner window has menus.
This includes the ability to rescan to filter out the pointers.
Just like you would a normal search.

Additionally, you only need 1 pointer to work, consistently. Even if you have 10,000,000 pointers in your pointer list, as long as the pointer that you have chosen continues to work, there is nothing more to do.

Better yet, forget about using the pointer scanner and use injection.

Many thanks for your help!! Very Happy
@Rydian
I know about the option scanpointer, but two problems:
1) scanning a pointer does means restarting level, and sometimes, even worse: restart the game... In a real game, unlike CE tutorial we don't get a button: "change the pointer"....
2) even in case of scanning, I start f.e. with: 1.000.000, and after many rescan I still am at f.e. 5785 and the number does NO longer decrease...
@++Methos
You are telling me to use injection, in other words patch the code so the game does no longer use pointers.
May you tell me where may I get some example to understand this?

MBR to all!!!

@danrevella, it is perfectly normal.

If you want to filter out most pointers, you have to rescan. And that means restarting level, restarting game, restarting windows....

And sometimes it is not enough. Then you can try:
- launch game from another windows account (which means you will start game from the scratch)
- saving rescan files (fifth rescan or even more) on USB key and continue rescanning on another PC is a good idea too.



"I start f.e. with: 1.000.000, and after many rescan I still am at f.e. 5785 and the number does NO longer decrease... "

This is normal too. Sometimes you will have millions, after rescan few thousands, after next rescan few hundreds, and it doesn't change. But, sometimes it can drop from 100'000 to zero while third rescan.

Some scenarios I encountered in the past:
( first value is initial number of pointers, next values are after rescan )
( Pointer Max Level 4 )

- 45'000'000, 100'000, 200, 190, 180, 180, 180

- 45'000'000, 100'000, after game level restarts 90'000, 80'000, 79'000, 78'000, after PC restart 20'000, 19'900, 19'800, other PC the same game 500, again on my PC 480, 475, 460

- 45'000'000, 100'000, after game level restart 90'000, after game restart 20'000, after starting new profile in game 0 (yes ZERO, I had to try level 5)

Ok, at least now I know I was not totally wrong.... Smile
BTW,
I'm really also interest in understanding the concept of bypassing pointers problem with injecting, I think as general rule is always important to know more then one solution for solve the problem.
Maybe you may submit to me some example?......... AHHH OK!
I was only stupid: I have to try about "avoid DMA", now go and study!

Many thanks for your patience Smile

Regarding injection, it's easy if you can right-click on the address in your cheat table, select 'find what accesses', and one of the instructions that shows up is ONLY accessing your address and no other address. However, if that is not the case, then the explanation that follows is very long and can vary, depending on your preferred approach.

First, I would learn how to do basic injection by completing the tutorial (if you haven't already done so). Then, you can find some of my previous posts that deal with this and see some of the example tables that I have posted.

You can right-click the address you're trying to find a good pointer to (when it's correct) and find what writes or accesses it, and if you find specific instructions (like Method said, that only access that address) and it's in the form of like eax+123, then you can assume that the game's proper pointer will have the last offset as +123, and tell the pointer scanner that pointers have to end with that offset (both during the initial scan, and a rescan).

This is unlikely to bring things down to just 1-2 results like with normal memory scans, but it's another way to trim the results to things that can be assumed to follow the game code more closely.

Many thanks for your suggestions!!
Do you think is a good idea when scanning for pointers to freeze the game?

You can even close the game during the scan (after the initial part with the progressbar is done)

I have followed your suggestions.
In the game Minesweeper (ita version is "Prato fiorito" Embarassed ), every time I get different adresses for time, so:
Code:
[ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(newmem,2048,"minesweeper.exe"+2B73F)
label(returnhere)
label(originalcode)
label(exit)

newmem: //this is allocated memory, you have read,write,execute access
//place your code here
xor rcx,rcx
originalcode:
test rcx,rcx
je minesweeper.exe+2B77B

exit:
jmp returnhere

"minesweeper.exe"+2B73F:
jmp newmem
returnhere:
 
 
[DISABLE]
//code from here till the end of the code will be used to disable the cheat
dealloc(newmem)
"minesweeper.exe"+2B73F:
test rcx,rcx
je minesweeper.exe+2B77B
//Alt: db 48 85 C9 74 37

This code solve the problem.
BTW, the street is still so long, but...... patience...
Thanks to this forum!!!!!
