I feel like a fool asking this but here it goes...

How can I use this information? Where would I get started?

Please don't bash me for this lol. It's like this is a huge canyon for me and I can't see the bridge to get across. Telling me to take the bridge to the other side doesn't server much purpose if I can't find it. I taught myself AutoIt (I know...) now I've been looking for something else to do.

c++?

Yes I was reading that before I made the post here. Linking me to lines of code doesn't help much if I don't know what to do with them.

If you were to use them what would you copy/paste them into? I would assume you COULD use just a plain text file but I'm sure you understand that's not what I'm looking for.

For AutoIt I needed to download the AutoIt core and I downloaded the SciTe editor for additional ease in coding. Now to use this stuff what would I need to get?

I do appreciate your response and feel kind of bad spamming up what seems to be a rather epic thread.

Edit: I really don't want to be spoon fed here I just need a starting point. Something I can run with. The code examples are amazing but I really don't know what I would need to use them.

Edit: Edit: http://www.edgeofnowhere.cc/viewtopic.php?t=432481

Is this what I'm looking for? If so then it's good news because I already have Microsoft Visual C++ 2008 Express Edition installed on my computer and I've been going through the included tutorial in my spare time.

ASMPTR(D2CLIENT, LoadAct_1, 0x62AA0) // Updated 1.13c

After banging my head against the table trying to generate some maps }:p

, I realized this address was wrong, it's 0x62AA0 not 0x62AAE

Some pointers useful for generating maps:

Code: Select all

FUNCPTR(D2CLIENT, InitGameMisc_I, VOID __stdcall, (DWORD Dummy1, DWORD Dummy2, DWORD Dummy3), 0x4454B) //1.13c
FUNCPTR(D2COMMON, InitDataTables, DWORD __stdcall, (DWORD _1, DWORD _2, DWORD _3), -10943) //1.13c
FUNCPTR(D2COMMON, LoadAct, Act* __stdcall, (DWORD ActNumber, DWORD MapId, DWORD Unk, DWORD Unk_2, DWORD Unk_3, DWORD Unk_4, DWORD TownLevelId, DWORD Func_1, DWORD Func_2), 0x3CB30) //1.13c

Code: Select all

struct d2client_struct { //1.13c
      DWORD dwInit;
      BYTE _1[0x20D-4];
      DWORD fpInit;
   };

D2COMMON_LoadAct: DWORD Unk_3 == difficulty
Func_1 being pfLoadAct_1, but you probably know this.
D2COMMON+0x3CB30 == ordinal 10951 fwiw.
D2COMMON_10316(0, dwMapSeed, _TownLevelNo, v12, v13, difficulty, _pfun1, _pfun2); would have to be LoadActMisc

FUNCPTR(D2COMMON, GetUnitDistance, int __stdcall, (UnitAny* pUnit1, UnitAny* pUnit2), -10522) // Not sure how reliable this is seem to work all unit type but can be a bit fuzzy in the results(off by a few steps[compounded off by one errors?])

UnitAny* D2COMMON_GetUnitInBeltSlot(Inventory* pInventory, DWORD BeltSlot); // -10455
that could be useful to others, Unknown can you see any caveats of this?

EDIT[0] - Added another random pointer.

can anyone please post the ptr for GetUnitState2 and GetUnitState3 from D2COMMON?

I need it for exp stats lol

also is pUnitTable the same as 1.12?

I've never used the other ones you mentioned, but I have this if it is what you were looking for.

Code: Select all

VARIABLE(D2CLIENT, pUnitList, LPUNITANY, 0x10A608) // 6FBBA608

Quick question; I had been using...

Code: Select all

FUNCPTR(D2WIN, GetHwnd, HWND __stdcall, (), 0x1A80D0) //1.12

So the 1.13c updated...

Code: Select all

FUNCPTR(D2GFX, GetHwnd, HWND __stdcall, (), -10048) // Updated 1.13c

confused me a little. Are these in fact equivalents? Or is there a seperate D2WIN GetHwnd that has not been found/posted as of yet?

They both give you the HWND of Diablo 2.

lord2800 · **Joined:** Fri Jul 05, 2002 8:51 pm **Location:** /sbin/

They're both identical.

its wrong. 0x9C00 = -10204 ordinal and it creates TextBox, also the args are incorrect.

Code: Select all

FUNCPTR(D2WIN, CreateEditBox, Control* __fastcall,   (DWORD xPos, DWORD yPos, DWORD SizeX, DWORD SizeY, DWORD LeftOffset, DWORD TopOffset, CellFile *ptCellFile, BOOL (__stdcall *OnAccept)(Control*), BOOL (__stdcall *OnClick)(Control *), DWORD isCloaked, cStylePrefs * ptPrefs),-10057)

I tried with AutoIT and works fine but...

Code: Select all

$Acc = 0x6FA2AF28

$HP = 0x6FBCA795

   $MHP = _MemoryRead($HP, $Handle, 'ushort')
   $MACC = _MemoryRead($Acc, $Handle, 'char[16]')

It is cool but i still dont understand why:
1. I must write ushort for HP
2. char for Account Name
3. dword for money

its hard for me to

And where i can get static pointer of current Gold? i am using cheat engine for it, but i cant find "green" pointer
