@spatti88 ,i already downloaded this files , do i have to edit VC++ Directories ( Include Directories& Library Directories ) as MadKnight said?
i installed Detours - Microsoft Research or it's usless now? , and where should i put extracted Detours.rar files

 

[spatti88]

nope, just put it into your folder of source code

Someone knows why i can't compile the Detours 3.0?

I've got VS 2012..

Everytime i try to compile i get "NMAKE: fatal error U1077

I've made everything that was explained in this thread

Of course i already google'd it, but everything i tried didn't work.

Yea I meant that the server is sending the requested animation back. I'm not at home so I can't post sources sorry...

when you go home

thx for helping

hello, I ask anybody if can give us a full skill (although one) to show how exacly it should look like, for example: sword dance (heard its easiest one) with full source code (*.h, *.cpp files) not only a part of it. I need it only to create own skills for my server (I will never make it for ppls just for fun). Only one skill to copy and paste. I tried serveral times to create a skill but always got animation without damage, server crash or simply cooldown without any reacion.

int itemnum = ((int*) itempointer)[13];

So just search for the question marks : )
int itemid = ((int*) itempointer)[?];
int itemprefix = ((int*) itempointer)[?];
int itemattributyouwant = ((int*) itempointer)[?];

Another Method to find those Attributes is to watch on the Console Writes:
Example:

Console__Write(
"Excess of Item Num : PID(%d), Index(%d), IID(%d), Num(%d), AddNum(%d)",
*(_DWORD *)(this + 32),
*(_DWORD *)(*(_DWORD *)(this + 40) + 64),
*(_DWORD *)(this + 36),
*(_DWORD *)(this + 52),
a2);

So now we know what Item PID, Index, IID, Num is.
As you can see Item Num is declare as *(_DWORD *)(this + 52), but this is simliar to
int itemnum = ((int*) itempointer)[13];, because +52 indicates 52 x 1 Byte shift and we make
13 x 4 Byte poop : )
So Item PID would be 32/4 = 8 (8 x 4 byte shifts [8])

i wanna get the used item index.

*(_DWORD *)(*(_DWORD *)(this + 40) + 64)
as far as i know that means the "this" pointer got at +40 another pointer witch i have to shift 64 bytes to get the item index

but how i do that ?

((int*) itempointer)[10][16];//10x4 bytes and 16x4 bytes
this isnt working.

you where searching for this ((int*)itemptr[10])[16] <--

i did all right step by step but i get any error if i want to release my .dll
he tell me:

1>dllmain.cpp(5): fatal error C1083: Data (Include) can't be open: "cstdio": No such file or directory

what i did wrong :S? anyone can help me ^^?

 

[jurczasiak]

hellp please tell me what did I wrong. I made Sword Dance and it gives damage to character not to monster :/

 

[Akamaru]

There can be a lot of reasons:
1. You're using CPlayer:amage
2. You're using only WriteInSight to display and mistaked targetid with playerid.

It's hard to say more, because you didn't give enough info.

 

[jurczasiak]

int __fastcall Knight_SwordDance(void* PlayerPointer, char* PacketPointer, char* PositionPointer)
{

const int nSkillID = 43;
const int nSkillGrade = 1;

int result;
int TargetId;
char Type;
void* PlayerID = 0;
void* TargetID = 0;
void* MonsterID = 0;
int nDmg = 0;

Server::CIOServer::ReadPacket(PacketPointer, PositionPointer, "bd", &Type, &TargetId);
void *MonsterPointer = Server::CMonster::FindMonster(TargetId);
Monster *monster = new Monster(MonsterPointer);
KPlayer *player = new KPlayer(PlayerPointer);
result = (int) MonsterPointer;


if(MonsterPointer)
{

nDmg = 99;

(*(void (__cdecl **)(void*, int, int, int))(*(DWORD*)MonsterPointer+0x58))(MonsterPointer, 7, 0, nDmg);

PlayerID = Server::CBase::Id(PlayerPointer);
Server::CChar::WriteInSight(PlayerPointer, 0x3f, "bddbbwwb", nSkillID, PlayerID, PlayerID, 1, nSkillGrade, nDmg, 0, 1);


}

return result;
}

I only want create simple skill 4fun

1. You shouldn't use things that you don't understand and when it's not necessary.
2. This is not true function call to deal damage. Analyze existing skill function to get it.

Use it as a base:

Look at MadKnight's posts, he posted shield offense pseudo code with renamed variables etc.

 

[jurczasiak]

first try to make Sword Dance because this skill don't has preskill.

2nd question:

just make NOPS at this error, or use my main.

Can anyone reupload this MainSrv.exe?

 

[spatti88]

it's clean mainsvrt, so u can get it from clean repack .

 

[jurczasiak]

Yes you are right but with your Main it doesnt show red errors - cant find skill ID. Thanks sry for bothering
Can You reupload please?

Some people have problems to get into the Reverse Engineering and maybe i am not the best Teacher : ) ..
but i saw some Youtube Vids today, wich should be usefull for beginners.
I recommend to watch these 3 Vids:
