[Holy]

Yesterday the user Charles_Ps requested me to code something similar to a NPC for make resets, so i coded it and i left here the code.

This code is a bit more long as you seen, than the other code that i released yesterday. This NPC asks you to be lvl 350 and to have at least 100.000 Zen, and then if you complete the requisites you will be reseted, but you need to relog.

You must hook there if you want, same as the other NPC.

00405AF6   $ /E9 75541400    JMP gameserv.NPCDeviasGuard

But if you want to put the code on another NPC search for NPCs and make the hooks correctly .

Som1 Can make a guild how to use that code?
i know assmble but i never try to convent my projects to dlls
so som1 can make a simple guild how to convent OBJ to DLL?
and what u meaning when u write
"00405AF6 $ /E9 75541400 JMP gameserv.NPCDeviasGuard"?

Well, first here is the compiled DLL. View attachment GReset.zip

If u want compile it with ur modifications: Do the changes in Lvl, Required Zen,.... after that

*.- First u need have installed MASM32
*.- then open command ( Start->Run->cmd ) then...

Assembling the DLL code is identical to a normal EXE file and it is done as normal with the following line:
\masm32\bin\ml /c /coff GReset.asm

This line will create a file named: GReset.obj


Linking the DLL:

\masm32\bin\Link /SUBSYSTEM:WINDOWS /DLL GReset.obj

This line will create the final file: GReset.dll

To HOOK the DLL in the GS:Hooking a DLL

and what u meaning when u write
"00405AF6 $ /E9 75541400 JMP gameserv.NPCDeviasGuard"?

this is the offset where u need to put a jump to the DLL hook, remeber , make a jump to the orignal address at the end

Thx man..oster_ss

 

[YEvil]

and whats from that? it just reduce money, nothing else coded ; ], but thanks

 

[-Rob3r-]

wow thx man

 

[RoRRe]

ok ^^ i got some critics on this code:
1. ->

Mov Edx, DWord Ptr Ds:[Eax + 0A0H]
Cmp Edx, 15EH

ok you are checking the lvl but where is the

Mov DWord Ptr Ds:[Eax + 0A0H],1

?

2. -> where is the reward of the reset ? =)
3. -> if you will make the reward then how you can see how many resets player alredy got ^^ ?
4. -> want it or not but you will need to work with mssql if you want to replace the web reset

 

[Holy]

There is no reward, but you are true this code doesn

 

[Di3Go_SM]

add me on msn..

diegoperfectsim1@msn.com

thx xD

 

[zolamu]

good job holy.

 

[Soultrain]

Good .. But the big problem is that some of the files used luciano aibar which of course has protected the gameserver.Dll or things are mine ..

The good idea is that we are just some of this new compilation and assamblar


The problem is that the guide is wrong fenix not seen either one of the images and this in English by my fate: S bueh Maverick if it is not too much to ask if we can pass aver a guide by you? For a well learn a little ... And what programs are needed for example I have visual c + + 2005 and Masm

I seems a good project! So we have no problems that users complain that they can not enter wing web reset or something so ...

Sorry for my bad English

Nice one .. but it better remain unfinished .. if you are not informed or don't know .. when making a reset ( in DB) without disconecting from the server it generates a bug ... in DB the stats are changed in game remains the same ... the changes take affect after reloging .. well if you dont you can reset 100000000 times for 1 count .. and i dont think you can pass this bug .. since mu was made like this from the start .. youl have to code both Server and Main from the start ... and still the only thing yoou will get is big lags .. and make new holes .. IM NOT TRYING TO FLAME.. im just being resonable .. you should better try your skils in useful development ( like fixing this damn visual bug ) .. and leave this reset thing to web coders .. to me it seems the only way .....

Sry for bad English

Thanks a lot Holy,

But would you mind sharing us C++ code if possible? I don't have any idea about asm.

Thanks again!

 

[Lisko]
