memoryReadInt

[el_dios85]

Hello,

Can memoryReadInt read null address?

Code: Select all

		pointer_offset = {0x8, 0x24, 0x18};
		local pointer = memoryReadIntPtr(proc, staticbase_ptr, pointer_offset);
		printf("pointer [%x].\n", pointer); 
		for i = 0, 768 do
  		  local tmp = memoryReadInt(proc, pointer  + i * 4);
		  local curbaseptr_addr = memoryReadInt(proc, tmp + 0x4);

			tarptr_addr = memoryReadInt(proc, curbaseptr_addr + 0x11C); --LINE 422
			if( tarptr_addr ~=  0 ) then
				tarbaseptr_addr = curbaseptr_addr;
				taridptr_addr = tartempptr_addr;
				coroutine.yield();
			end
		end

The Result is:

Code: Select all

pointer [8be0628]
WARNING: Failure reading memory from 0x2D4FDC0 at 0x4 in memoryReadInt(). Error code 299 (Only part of a ReadProcessMemory or WriteProcessMemory request  was completed.)
script\pwenak2.lua:422 attempt to perform arithmetic on local 'curbaseptr_addr' (a nill value)

because of the looping, local curbaseptr_addr = memoryReadInt(proc, tmp + 0x4); contain null value.

this is the result in auto it

Code: Select all

		Local $POINTER = memread(memread(memread(memread($APP_BASE_ADDRESS) + 0x8) + 0x24) + 0x18)
		ConsoleWrite("Pointer=" & Hex($POINTER) & @CRLF)
		For $I=0 To 768
			Local $CUR_BASE = memread(memread($POINTER + $I*0x4) + 0x4)
			ConsoleWrite("Cur Base=" & Hex($CUR_BASE) & @CRLF)
			ConsoleWrite("TAR Base=" & Hex(memread($cur_base + 0x11C)) & @CRLF)
			If $TAR = memread($cur_base + 0x11C) Then
				$TAR_BASE = $CUR_BASE
				$TARID = $TAR_TEMP
				ExitLoop
			EndIf
		Next

The result is

Code: Select all

Just add

Code: Select all

if( curbaseptr_addr ) then ... end

around the section of code that relies on curbaseptr_addr to be valid.

And no, you cannot read from 'nil', because 'nil' is something that doesn't exist. It's not a number, therefor, cannot be used as an address.

Thanks, it works, now the problem only that warning... I try it first..

[el_dios85]

It already Solved. Thank You Admin

Auto IT:

Code: Select all

	Local $TAR_TEMP = memread(memread(memread($APP_BASE_ADDRESS) + 0x20) + $OFFSET_AT)
	Local $TARID_TEMP = memread(memread(memread($APP_BASE_ADDRESS) + 0x20) + $OFFSET_AT)
	
	If $TAR_TEMP = 0 Then
		$TAR = 0
		$TAR_BASE = 0
	ElseIf $TAR_TEMP <> $TAR Then
		$TAR = $TAR_TEMP
		Local $POINTER = memread(memread(memread(memread($APP_BASE_ADDRESS) + 0x8) + 0x24) + 0x18)

		For $I=0 To 768
			Local $CUR_BASE = memread(memread($POINTER + $I*0x4) + 0x4)
			If $TAR = memread($cur_base + 0x11C) Then
							ConsoleWrite("Pointer=" & Hex($POINTER) & @CRLF)
							ConsoleWrite("Cur Base=" & Hex($CUR_BASE) & @CRLF)
							ConsoleWrite("TAR Base=" & Hex($TAR) & @CRLF)
							ConsoleWrite("TAR Base1=" & Hex(memread($cur_base + 0x11C)) & @CRLF)
				$TAR_BASE = $CUR_BASE
				$TARID = $TAR_TEMP
				ExitLoop
			EndIf
		Next
	EndIf

Result:

Code: Select all

In MicroMacro:

Code: Select all

	if(tartemptptr_addr == 0) then 
		tarptr_addr = 0;
		tarbaseptr_addr = 0;
	elseif(tartempptr_addr ~= tarptr_addr) then
		tarptr_addr = tartempptr_addr;
		--printf("tarptr_addr [%x].\n", tarptr_addr); 	
		pointer_offset = {0x8, 0x24, 0x18};
		local pointer = memoryReadIntPtr(proc, staticbase_ptr, pointer_offset);

		for i = 0, 768 do
         		local tmp = memoryReadInt(proc, pointer + i * 4)
			--printf("tmp [%x].\n", tmp); 
                if (tmp ~= 0) then
        		local curbaseptr_addr = memoryReadInt(proc, tmp + 0x4);
		

		
			if(curbaseptr_addr) then
				tarptr_addr1 = memoryReadInt(proc, curbaseptr_addr + 0x11C);
				--printf("tarptr_addr1 [%x].\n", tarptr_addr1); 
			end

						taridptr_addr = tartempptr_addr;
						break;

Result:

Code: Select all

I'm sorry, can anyone help me... I'm very confuse now... after success find the "target base offset", now the problem is, it cannot read the "Target HP". Is there something wrong about micromacro memoryReadIntPtr function?

This is the source and result (Auto IT)

Code: Select all

							ConsoleWrite("Pointer=" & Hex($POINTER) & @CRLF)
							ConsoleWrite("Cur Base=" & Hex($CUR_BASE) & @CRLF)
							ConsoleWrite("TAR Base=" & Hex($TAR) & @CRLF)
							ConsoleWrite("TAR Base1=" & Hex(memread($cur_base + 0x11C)) & @CRLF)
							ConsoleWrite("TARHP=" & Hex(memread($TAR_BASE + $OFFSET_TARHP)) & @CRLF)
							ConsoleWrite("HP=" & Hex(memread($CHAR_DATA_BASE + $OFFSET_HP)) & @CRLF)

Pointer=08DD72F8
Cur Base=16291010
TAR Base=80103DEF
TAR Base1=80103DEF
TARHP=0000001D
HP=0000034A

and This is from MicroMacro

Code: Select all

						printf("pointer [%x].\n", pointer); 
						printf("curbaseptr_addr [%x].\n", curbaseptr_addr); 
						printf("tarptr_addr [%x].\n", tarptr_addr); 
						printf("tarptr_addr1 [%x].\n", tarptr_addr1); 
						printf("TARHP [%x].\n", memoryReadIntPtr(proc, tarbaseptr_addr, TarHP_offset));
						printf("HP [%x].\n", memoryReadIntPtr(proc, charptr_addr, HP_offset));

pointer [08DD72F8].
curbaseptr_addr [161B4CB0].
tarptr_addr [80103E66].
tarptr_addr1 [80103E66].
TARHP [30000059].
HP [34A].

The value always 30000059.
I have try all of the function memoryReadUIntPtr, memoryReadBytePtr,memoryReadUBytePtr, memoryReadShortPtr, memoryReadUShortPtr, memoryReadFloatPtr, etc...

in auto IT the memread function source:

Code: Select all

Func memread($adress, $type = 'dword')
	Local $struct = DllStructCreate($type)
	DllCall($kernel32, 'int', 'ReadProcessMemory', 'int', $mid, 'int', $adress, 'ptr', DllStructGetPtr($struct), 'int', DllStructGetSize($struct), 'int', '')
	Return DllStructGetData($struct, 1)
EndFunc

memoryReadIntPtr(proc, tarbaseptr_addr, TarHP_offset)

Maybe that should be:

Code: Select all

memoryReadInt(proc, tarbaseptr_addr + TarHP_offset);

Also, a few of your other addresses are off. You're making progress at least.

[el_dios85]

yes, it work.... i try the wrong way before.
like this memoryReadInt(proc, memoryReadInt(proc,tarbaseptr_addr ) + TarHP_offset);
and it didnt work....

Thank you very much, this target info session is completed.

I want to try to translate other function from Auto IT to micromacro.
