sry i do not beleive this is what im looking for, what im looking for is for example: i use Tsearch to locate a memory address in an exe, lets say the value of the address im looking for changes to below a targt number like 500, i would like autoit to be able to detect that the value of this address has decreased and then have autoit perform a function after that.

I'm not an expert in using memory stuff

But seems to me that what you want to do is like:

#include <_Mem.au3>

$Process = ProcessExists("PROCESSNAME.EXE")
If $Process = 0 Then
     MsgBox(16, "Error", "The process doesn't exists!")
     Exit
EndIf

$Address = 0x00000000
$Handle = _MemOpen($Process)
$Value = _MemRead($Handle, $Address)

While 1
     If _MemRead($Handle, $Address) < $Value Then
          YourFunctionHere()
     EndIf
WEnd

Func YourFucntionHere()
     _MemWrite($Handle, $Address, $Value)
EndFunc

I just wrote this, i didn't test it.

Hope it helps.

He gave you the link to it in post 2, look at the function calls and look at the 1st post.

You must have AutoIt Beta or the new stable 3.2 release.

#10 ·  Posted (edited)

ah im n00b, i shudnt have posted so soon, because righ tafter i posted i searched for the commands in my error and found that i had to download the beta, thanks for repling so quikly tho.

now the code is working.. with one small problem

#include <_Mem.au3>

$Process = ProcessExists("knightonline.exe")
If $Process = 0 Then
     MsgBox(16, "Error", "The process doesn't exists!")
     Exit
EndIf

$Address = 0x1D0CC00
$Handle = _MemOpen($Process)
$Value = _MemRead($Handle, $Address)

While 1
     If _MemRead($Handle, $Address) < 250 Then
          Call("Pot")
     EndIf
WEnd

Func Pot()
     Send("{5 down}")
     Sleep(100)
     Send("{5 up}")
     Sleep(1500)
EndFunc

i want the func Pot to be called when the Value of the address goes down below 250.

problem is ... the $value variable isnt returning a number, but its returning a "True".

how do i make autoit Read the Address's value?

_MemRead should do this. I don't see any problem. You may want to PM w0uter and ask him.

the problem is, my original post said i need autoit to detect if the value of an address has gone below a set number, and the code given to me does not do that.

i appreciate the help VERRY much and i will pm w0uter to see if he has suggestions.
