Perhaps use the move action struct to move to your current position?

02/20/2012 11:12 amineurin#302

hm............i give it a try, i just remove all action struct for moving.
since the mobs is wandering, bot walk to old mob possition and then attack, looks a bit wirred.

with the send packet, he follow the wandering mob while running to him :)

but for stopping, it can be god enough.
thanks for the hint, sometime i cant see the tree in the wood :D

The good old walk through door trick.
can't live without it.
btw, thanks ami for the epfollowleader tips.
I finally figure it out and get it to work.

It's weird that MemoryPointerRead and Write fail to work, and I have to make another set of functions to work around that. Maybe its because I'm using win7 64bit? You mentioned to have some difficulties with AutoIt run on the OS. Could you share what your experiences were?

many thanks

many thanks

the problems u descripe come from the actual autoit version 3.3.8.1
u have to rewrite some things in the nomadmemory.au3, since in the new version there some syntax changes.

like this:

Quote:

Hex(DllStructGetData($v_Buffer, 2))

comes to

Hex(Int(DllStructGetData($v_Buffer, 2)))

if u to lazy to rewrite, grab autoit version 3.3.6.1
works fine without changing anything ;)

Hi!

I have problems getting selecttarget packet to work.

My package looks like this: Package: '0200217E1080' ;Vanguard Isis
sendPackageFunction at 0x63AA80

I use AutoIt and the code from the first post in this thread.

If I manually click a target I can see that at the start of the sendpackage function esi already contains a pointer to the package to be sent.

If I let the injected code call it the esi register doesn't contain that pointer.

Isn't it enough with the package pointer and package length beeing pushed to the stack before the call, do I need to put it in the esi register?

Hoping you guys can help me out, thanks in advance ;)

Edit: Problem is solved. I didn't use the real base address but some other baseAddress I found in an other forum. With a521c0 as realBaseAddress it worked fine.

Hi all!

Regarding the regexp to find the invite struct in the start of this thread I have updated the reg expression to find the invCounterBase:

$search = StringRegExp($data, _
'8B85(.{8})' & _
'8B4C2414' & _
'8B542420' & _
'2B54080C' & _
'8DB5.{8}' & _
'03C1',2)

If Not @Error Then
$invCounterBase = hex(dec(rev($search[1])) + 0x20)
EndIf

Hope it will help someone.

any one know the new packet for refreshing the auction hall page ?
i got it some time ago from dumbfck, but its not working after descent update :(

thx :)

It's only changed a little bit... The "00000001" at the end seems like it can be anything, but then "14" has changed to "40".

Code:

Func updateAhPage($playerId, $pageOffset, $pid)
    local $packet, $packetSize
    
    $packet = '25001A00'
    $packet &= '00001700'
    $packet &= '00002403'
    $packet &= '0000'
    $packet &= _hex($playerId)
    $packet &= '0000'
    $packet &= '00000000'
    $packet &= _hex($pageOffset, 8)
    $packet &= '00000000'
    $packet &= '40'
    
    $packetSize = 33
    sendPacket($packet, $packetSize, $pid)
EndFunc

And to update gold listings:

Code:

Func updateGoldListings($playerId, $pid)
    $packet = '25002B00'
    $packet &= '00000C00'
    $packet &= '00009701'
    $packet &= '0000'
    $packet &= _hex($playerId)
    $packet &= '00000000'
    
    $packetSize = 22
    sendPacket($packet, $packetSize, $pid)
EndFunc

Enjoy :D

Thanks dumbfck :p

I'm not able to do anything atm, either my MB or HD is dying... busy trying to figure out which :o

Without you and a few other people, this section would be dead. I do not have any use for this, but thanks for always checking around here. Thought i'd say that.

03/27/2012 13:46 amineurin#311

i think same, dont know exactly how much i coded from the infos i get from you here.
wish u good luck on your hd, interest07.
know it wen the feeling came "aaaah i can lost all my stuff", its a nightmare :(

03/27/2012 18:58 dumbfck#312

Ami has pointed out that my code was wrong... I had cheated and hardcoded my player ID in because I couldn't be arsed to read it from the client first, and hence I didn't test that bit properly :p
Sorry, here's the revised code with some parts from Interest07's original program. You should be able to run it as-is - Just comment one of the lines out to test the AH or the Gold listings (only leave one of them uncommented otherwise you'll get a 'service unavailable' message in game from the other one)

Code:

;updateAhPage($playerId, $pid)
updateGoldListings($playerId, $pid)

#include <ProgressConstants.au3>
#include <StaticConstants.au3>

Oh and good luck wth your computer, Interest07 >.< - Hope you had backups!
I know all too well how fecking annoying it is losing everything... I managed to accidentally format my backup drive once lol. Was re-installing Windows and had left my USB hard drive plugged in - Windows very helpfully identified the external hard drive as drive C: so I chose that one for the format. Epic double facepalm headdesk.

Thanks, and lmao ouch!!

I've been able to move the most important files to an alternate drive. Luckily it didn't always crash on startup, but sometimes took 0-60 minutes :p

I plugged ina different HD now to see if its the HD or the MB that's causing the crashing. Problem is... I replaced this HD for a reason, but I can't recall what it was, so it might be faulty as well :p

Thanks again dumbfck :)
heres the one which updated a specific page, were $Page is the amount of auctions.
every page has 16 auctions, so lets say we want to see page 10 then $Page=160
or to get every page from 1 to end....

first run:
$Page=15 ;(auctions 0-15)
updateAhPage....
;next page:
$Page +=16
updateAhPage....
....

Just to share with you guys, i converted AutoIt code for ActionStruct to Delphi

  SetLength(result, SizeOf(Buf) * 2);
  BinToHex(@Buf, PChar(result), SizeOf(Buf));

Function HexToFloat(const s: string): extended;
{ Converts hex of floating point with sign flipped to float value. }
type
