Does it really take 136 Hours to loop 3144108000 times?

[goldenix]

So Hire it is, my personal memory scanner sample. If I use CE to do the first scan it takes 1 second, at worst 10 seconds.

With this scanner hire, 136+ Hours.

Now the question is: did I screw up with the time difference & conversion from KB to bytes.? The wiki says 1KB = 1000 & 1 KB = 1024. so witch is it?

And if I want to convert my memory into bytes its Memory *100 tight?

CTRL+F & search for TimerInit & MemGetStats

; Description ...: Returns a string representation of an integer converted to hexadecimal.
; Parameters ....: expression   - The integer to be converted to hexadecimal.
;                               - [optional] Number of characters to be returned (no limit).
;                                 If no length specified, leading zeros will be stripped from result.
; Return values .: Success      - Returns a string of length characters representing a hexadecimal expression, zero-padded if necessary.
;                  Failure      - Returns "" (blank string) and sets @error to 1 if expression is not an integer.
; Author ........: jennico (jennicoattminusonlinedotde)
; Remarks .......: Output format "FFFF".
;               The function will also set @error to 1 if requested length is not sufficient - the returned string will be left truncated.

While K (short for kilo) stands for 1000, there is actually 1024 bytes in a kilobyte (KB).

You're doing it wrong. You can't scan every address, or it will take ages. You must scan large chunks and evaluate those. Call MemoryRead as LITTLE as possible.

Here's a post of mine that may help.

NomadMemory.au3 is one of the stupidest things I saw written in AutoIt.

[darkjohn20]

Really? I find it extremely useful.

[JohnOne]

I tried doing this once and wound up with the same old scabby problem of it taking ages, afterreading, it seemed you need to create some sort of buffer, load a bucket full off addresses into it and process it like that.

Anyway, to shorten my story, It was way over my head, so I just automated cheat engine

[trancexx]

You wouldn't be the only one. That file is obviously very well known.

I just can't figure why? What's so special about it? It's for example badly written and it's also completely unnecessary.

Enigma.

It was based on w0uter's functions which where inherently a bit hack-ish since native language support for doing it easier didn't exist, (DLLCall and DLLStruct functions were still a little buggy). Being the (one of the) first counts for a lot, even if it aint the best.

We are talking about programming here, not having sex.

Being the first one means nothing. If there are better ways, don't use bad ways.

Though, I'm sure majority of the people using NomadMemory.au3 wouldn't understand what I just said. Never mind, I'll just say it few more times.

Why be so cryptic trancexx? If you want to persuade people you need to give some reasoning. I have used Nomadmemory myself and what I remember about it is that it worked. To me, that is the first requirement of a tool. The second requirement is that it is reliable and safe, the third that it is easy to use, the forth that it is easy to change. If it meets those tests then it how it's written is not so important, and if it meets those tests then why is it so stupid? Presumably because you see some fault which can cause problems. So we need to know don't we?

You said if it meets those.

If we are talking about the same file then:

• It may work an it may not work. Too many things are left to influence that.
• It is not reliable. It's not safe.
• It's made hard to change considering how it could have been made.

I wouldn't know about easy usage. I never tried it.

Ok, but can you tell us why it's not reliable or safe?

[trancexx]

You are playing psychology with me.

In that manner the answer would be, because it's written that way.

You should use standard _Winapi... functions for safety.

For reliability you would write functions yourself.

[Juvigy]

You say there is a better way - please educate us.

90% of the people that use it dont know there is a better way.

[AndyG]

 

90% of the people that use it dont know there is a better way.

Are you joking? 90% of people who use it know anything about it!

Yes, it´s one of the quick´n dirty tools, mostly used by some "kiddies" to write Gamebot Scripts. And that's the reason why questions like the topic are written. 

Btt: trancexx gave you more then one hint....

Edited April 26, 2010 by AndyG

[Juvigy]

Yes , i got him , but dont understand why he doesnt give examples and exact information

instead of hints and tricky pointers.If he post some examples and exact info we can compare

the nomadmemory and the other methods and say: "this is 5 times faster" , "this is so much easier to use" etc.

This is not only used by kids for bots.Unfortunately i havent used nor nomadmemory nor other methods yet so i cant post any examples.
