Hi, I'm new to CE only started using it about a week ago.

So far I have managed to find a 3 level pointer for the character name in FFXIV.
Code:
Pointer := 0x00E8D368
offset0 := 0x144
offset1 := 0xE0
offset2 := 0xE2


Using AHK I can read the "dynamic" address, But the results are returned as it's 4 Bytes data type.

My first question is.. Using AHK, How can I return this value as it's String[30] non-unicode data type? Like you can in CE.

My next issue is.. Using AHK, How can I read the value from the pointer& offsets?

I believe it's a problem with my DllCall but all my attempts Have so far failed.

Here's my attempt so far:
Code:
;//function ReadMemory
ReadMemory(MADDRESS,PROGRAM = "ffxivgame.exe")
{
   Process, wait, %PROGRAM%, 0.5
   pid = %ErrorLevel%
   if pid = 0
   {
      MsgBox The specified process could not be found.
      return
   }

   VarSetCapacity(MVALUE,4,0)
   ProcessHandle := DllCall("OpenProcess", "Int", 24, "Char", 0, "UInt", pid, "Uint")
   DllCall("ReadProcessMemory","UInt",ProcessHandle,"Uint",MADDRESS,"Str",MVALUE,"UInt",4,"str P",0)

   Loop 4
   result += *(&MVALUE + A_Index-1) << 8*(A_Index-1)

   DllCall("CloseHandle", "int", ProcessHandle)
   
   return, result 
}

;//Current Dynamic address
DynAddr := 0x07A9EE7A       
DynResult := ReadMemory(DynAddr)

;//Static Pointer
Pointer := 0x00E8D368
offset0 := 0x144
offset1 := 0xE0
offset2 := 0xE2

   addr0 := ReadMemory(Pointer)
   loop,3
   {
      i := (A_Index - 1)
      addr%i% := addr%i% + offset%i%
      addr := addr%i%
      addr%A_Index% := ReadMemory(addr)
   }


;//View results

Any help would be greatly appreciated. Thanks!

Ok, using Autohotkey, I can now read strings from a specified memory address.

But can't seem to do it with a lvl-3 pointer, In CE this pointer always returns the Character name. I just cannot replicate it in ahk.

Any help with reading multi pointers in AHK would be much appreciated, thanks!

Code:
;//function ReadMemory
ReadMemory(MADDRESS, pOffset = 0, PROGRAM = "ffxivgame.exe")
{
         Process, wait, %PROGRAM%, 0.5
         pid = %ErrorLevel%
         if pid = 0
         {
            MsgBox The specified process could not be found.
            return
         }
         VarSetCapacity(MVALUE,4)
         ProcessHandle := DllCall("OpenProcess", "Int", 24, "Char", 0, "UInt", pid, "UInt")
         DllCall("ReadProcessMemory", "UInt", ProcessHandle, "UInt", MADDRESS+pOffset, "Str", MVALUE, "Uint",4, "Uint *",0)
         DllCall("CloseHandle", "int", ProcessHandle)
         Loop 4
            result += *(&MVALUE + A_Index-1) << 8*(A_Index-1)
            
         return result
}


;//function ReadMemory_Str
ReadMemory_Str(MADDRESS, pOffset = 0, PROGRAM = "ffxivgame.exe")
{
         Process, wait, %PROGRAM%, 0.5
         pid = %ErrorLevel%
         if pid = 0
         {
            MsgBox The specified process could not be found.
            return
         }
         ProcessHandle := DllCall("OpenProcess", "Int", 24, "Char", 0, "UInt", pid, "Uint")
         teststr =
         Loop
         {
            Output := "x"  ; Put exactly one character in as a placeholder. used to break loop on null
            tempVar := DllCall("ReadProcessMemory", "UInt", ProcessHandle, "UInt", MADDRESS+pOffset, "str", Output, "Uint", 1, "Uint *", 0)
            if (ErrorLevel or !tempVar)
            {
              DllCall("CloseHandle", "int", ProcessHandle)
              return teststr
            }
            if Output =
              break
         
            teststr = %teststr%%Output%
            MADDRESS++
         }
         DllCall("CloseHandle", "int", ProcessHandle)
         return, teststr 
}



;//Current Dynamic address
DynAddr := 0x07A9EE7A       
DynResult := ReadMemory_Str(DynAddr) ;//Returns: Character name in FFXIV

;//Three lvl Pointer in CE which always Points to the Character name
Pointer := 0x00E8D368
offset0 := 0x144
offset1 := 0xE0
offset2 := 0xE2

PointerResult1 := ReadMemory(Pointer, offset0)
PointerResult2 := ReadMemory(PointerResult1, offset1)

PointerResult3 := ReadMemory_Str(PointerResult2, offset2) ;//??? Does not Return: Character name in FFXIV ???
