Understanding Development of GameServer Files and Main.exe

[CockMan]

Frequently asked questions (+ Reliable Answers)

Q. Why doesn't my server have full s3 items support, i mean i can wear the items, get the added def, but when it comes to viewing them by others, it shows up all wrong?

A. You must first correct the gameservers errorwith the visual interaction bug for the items. Gameserver requires correct procedure and offsets to show the items correct to all.

Q. Why do all the big named servers have all these cool features and when I look on RZ I cant find anything compared to that?

A. They simply leech, buy files, or create them themselves. It is not hard to code, ppl are just too lazy to learn it.

Q. I am running a server, but no one seems to be coming to it, what is the problem?

A. You must advertise it widely, good example is alliance mu or zypher mu, no matter what the admins do bad to the game, its soo widely advertised more ppl will come to it.

Q. I want to add more items to my game, how do i go about doing that?

A. To make the items visible you must first study and understand Q. #1, and the second part is to call new .smd functions from a dll source to memory, then into the mains debugger.

Q. I want Season 3 Server, How to obtain?

A. Make it yourself, you can prolly learn to code and then make your own server perfect in less than 3 months.

Is simple guide to answer basic questions without giving away too much information. Some leechers will understand and some dont, if you dont i suggest you leech files from rz and other forums.

In the past I have released help for ppl to create their own 3d camera on older clients, but now I will release the fully functional 3d for newer s3 compliable servers.

Credits? all go to Rz, this post is to show ppl what to think and how to think, is merely education guides on how to answer / obtain information.

Truel, only a idiot wants fully customizable files without working for them. xD

[shay2134]

plz you can learn me how to code i want to know and i dont find how to code i so want to code but i dont know if you help i thank you all my life plz learn me to code

[hutzu]

well.....many of us want to learn how to code those gameservers and mains and all other stuff, but we don't know where to start.

[Marin_scp]

Can you tell us a good start-point to learn devoloping GameServers? I am very interested in developing my own gameservers, but I just don't know where to start.


(Sorry for bad english, I am brazilian).

[zimbred]

Lol, Assembler? Are you masochist?

Learn C++, or different High-Level language, and a bit asm, only for debug (mov, ptrs, cmp, jxx, push, pop, add).

You must know well Win32Api, understand pointers to datas or functions (because GameServer is simply Framework) in C++ and have PDB (GameServer 0.99.60 and 0.99.62 have it). Additional you can reverse some MuOnline protocol (NPC Talk, skills) and cryptography (C3 and C4 enc/dec).

If you will know this, you can make with MuOnline everything. Simple ;).

[CockMan]

xD that 3d main looks similar to sobiehs full 3d main, but its still goo, any more bit of info to help out is greatful, do it for rz and spread a few good c++ tuts.

[zimbred]

No, it's not similar.

If I remember well, sobieh steered his camera by mouse and screen edges.

My camera using mouse gesture. If you click 3rd button and:
-drag mouse int left or right: camera will rotate,
-drag mouse in up or down: camera will zoom out or zoom in,
-scroll steering camera perspective.

[CockMan]

hmm correct. but its easy to manipulate camera, tho most teams us the 1.2n limited way. Also, I think I saw your compiled source of kanturu even pasted on CzF.

[RisingKing2010]

it also helps to look at any sources u can get your hands on, u can see examples of how a coder would add a simple option...

like here is part of the /post cmd:

Command = szChatBuff;
if(strcmpi(Command,"/ServerInfo")==0)
{
	 MyChat.ServerInfo(lpObj);
}
else if(strcmpi(Command,"/Post")==0)
{
	MyChat.SendPost(lpObj,Content);
}
		else if(strcmpi(Command,"/Test")==0)

this was taken from a czf dll source i found perusing the i-net, but it is gone now :P, the czf added a few other options too, as u can see, i am still too nooby at C++, so i dont rly understand major parts source that much XD, and sry wont post the full source b/c it isnt my source :P

so for this i will give credits to CzF :P

this is a small part of the function...

[kazanliev]

I am reading this thread for the third time and I just can't understand how much insanity it takes to write something like that. A Q&A pretending to be the masterpiece .... ultimate guide to the perfect private Mu server.
Let me ask you this: If all the so called n00bs who want to create a decent private server and are staying here on RZ and read, test and post, learn how to code just following your guide, how many "Active supporters" of CzF would remain?
Your whole post is so disrespectful to the community it leaves me speechless.
Don't get me wrong!!! I do respect the work of CzF and all other coders and teams. They do all of their work for the credits ONLY and they do deserve respect. But you my friend are a hypocrite. You SHOUT as hard as you can how you support the coders and at the same time you are simply a leecher who leeches first hand.
May be I am wrong, may be you are the best coder out there but if that is so why I can't see your name on the credit list of CzF. If you are supporting CzF so damn hard why didn't they put you on the list of credits they give?
As these rows are growing another idea came to me: I haven't heard of CzF members looking for supporters. Really, show me just one post of a CzF member asking for supporters (fans) and I'll apologize.
May be I am wrong again, but my curiosity still grows: Mate, how are you supporting CzF? What are you doing to support them? Really, I want to support them too, I am serious about it. I'd like to see my name in the list of their supporters when they publish it, if there is such a list at all.

[kazanliev]

At the end I'll ask you another simple question: Read the two lines on my signature and tell me: Do they seem funny to you? Answer with a simple yes or no.

omg, stfu, u take this too seriously, so wat if ppl are "CzF Supports" it doesnt make that much of a difference... and CockMan gots a very good point, most ppl just use files they find here rather than code themselves... most of the best server dont use files ragezone, they, like cockman said, either buy/code them

the world isn't perfect, but you will just have to live with it

[RapidBlue]

all i have to say on this is im not going into this but thx cock for the guide :D

A. GS dont need to show visual things, its a little moron to say than GS show visual, in fact it only send a packet with the new items ID on other bytes and main show the animation, its just a packet send interaction nothing releated to offsets

Salut,
f1x

In fact i code on ASM and my progress is much superior than to mod kantru event, i also got MU S3 mixs, golden fenrir, new class, new wings options and custom events...

ASM its much superior than C++ on speed, it only take time to code it, but some lazy option its to learn C++ xD.

Example of retard C++ code in compilation:

C++:

mov eax, Local1
add eax, 1
mov Local1, eax

ASM:

add Local1, 1

MemCopy C++ can be used and most used has a API, on ASM you can produce your own proc less than 8 lines for do the same in a very superior way.

PS: I code also PICs (robotic) and thats why i know most PICs coders use ASM for the compilation, less lines on compile and less resources used.

[zimbred]

In fact i code on ASM and my progress is much superior than to mod kantru event, i also got MU S3 mixs, golden fenrir, new class, new wings options and custom events...

And? You can make this shits using only funcions implemented in GameServer (ItemSerialCreateSend, ChaosBoxInit), sniffer, decryptor and some packets. My Season3 mixes had only ~15 lines code in C++.

ASM its much superior than C++ on speed

And it's the most bugless way to code something in mu. In C++ you have more advance mechanisms, like polymorphism, inheriting and predefine compile profiles. In ASM you have only procedural coding. In C++ your code is more clear than assembler and it's more receptive on changes, so you should learn C++. Now i know C++, ASM and some Delphi and coding in C++ is the most effective for me.

C++:

typedef int(*pItemSerialCreateSend)(DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD, DWORD);
pItemSerialCreateSend ItemSerialCreateSend = (pItemSerialCreateSend)0x004036BB;
ItemSerialCreateSend(aIndex, 0xFF, gObj_GetInt(aIndex, gObj_POSX), gObj_GetInt(aIndex, gObj_POSY), WingsId, 0, 255, 0, 0, 0, -1, 0, 0);

ASM:

PUSH 0
PUSH 0
PUSH -1
PUSH 0
PUSH 0
PUSH 0
PUSH 255
...
...
...
...
(and more)
MOV EAX, 0x004036BB
CALL EAX

Show your code Kanturu Event in ASM and compare it with my Code in C++:
.: Coderz Factory Network :. .

Maybe some day I release my code for Illusion Temple Event and 3rd Level quest, of course in C++, so you can compare coding in ASM and C++ more in detail ;).

Its very easy to know ItemSerialSend but do you know the arguments how they work???... i believe coding its not just copy and paste:

Push 0
 Push 0
 Push - 1
 Push 0
 Push 0
 Push 0
 Push 0FFH
 Push 0
 Mov Eax, WingsID
 Push Eax
 Push 0
 Push 0
 Push 0FFH
 Push Edx
 Call CreateItemSend
 Mov Eax, MixlpObj
 Mov Edx, DWord Ptr Ds:[Eax]
 Push Edx
 Call InvCommit

Yeah you can some day end coding new class i mean 3 years more xD...

Compare the my wings source code:

MixRecv Proc
Local TypeMix:DWord
Mov Eax, DWord Ptr Ss:[Ebp + 0CH]
Mov TypeMix, Eax
Xor Eax, Eax
Switch TypeMix
Case 25H
Mov Edx, DWord Ptr Ss:[Ebp + 8]
Invoke NewWingsMix, Edx
Mov Eax, 1
Case 26H
Mov Edx, DWord Ptr Ss:[Ebp + 8]
Invoke FinalMixWings, Edx
Mov Eax, 1
EndSw
ret

14 lines caused first 2 dont count, and only source code, C++ compiler make 15 lines of you to 30 meaby xD.

Can i wonder whats Illusion temple type packet??? caused i got them all, but can you tell me just one?? xD

In C++ your code is more clear than assembler and it's more receptive on changes, so you should learn C++. Now i know C++, ASM and some Delphi and coding in C++ is the most effective for me.

SCF team code on C++, they got much more than to code easy wings mixs, i can bet they tell you ASM is superior xD.

If not search on google the compilation, and polymorphism has nothing to do, meaby people think caused you say weird words you know more, but for be more sure, themida packer use polymorphism system on ASM and pholymorphism create much more lines on compilation and in source code, polymorph code it increase lag and speed, i wonder why you name it on MU?? meaby caused weird words make people think you know alot xD.

C++ Retard compilation has we see:

MOV EAX, 0x004036BB
CALL EAX

ASM Compilation:

call 004036BB

(1 line less and no EAX regist used)

PS: Hey sobieh if you reading this laugh a little, polymorph on C++ make the compilation faster hahahaha xDDD

[bet0x]

SCF team code on C++, they got much more than to code easy wings mixs, i can bet they tell you ASM is superior xD.

I agree with FeN$x this time, but no always ;), ASM its fast and superior, but a pain of ass if you made for example 6 events, simples can be, but harder, you dont have Objects but its really fast.

[zimbred]

No, polymoprhism and others object oriented featues in C++ doesn't make C++ faster (in several cases) than ASM, but code is more regularized, besides code effectivity it's not only one point (see source of MANGoS emulator).

I saw some your source (example Fenrir mix) and it's very chaotic.

btw. Your source of season 3 miexes is incomplete, it's only protocol core hook ;). Show your mix functions...

Ym, now i must finish code ELF MP3Player for My siemens CX65@70. See you later :).

[FeN$x]

LoL mix dont need protocol core hook hahahaha, they just need to be hook on looper of mixs proc, its not protocol core xD.

And fenrir mix source was public, my source publics are coded on minutes, mine there its working and for you can test new class and golden fenrir with all working including mixs and custom things enter to my server:

200.104.20.46

Anyone than want to enter allowed, use the account:

user test1
pass test1

New class workings, S3 mixs working, custom events working, golden fenrir full working with options, /Adds commands working, /Post and /ServerInfo, NPC Silent teleport working, S3 custom drops working also.

You can see DeathWay source code GS on C++, and you can still ask him if ASM its more faster and much more complete on compilation than C++.

Also ASM is more bug free, ASM also used for profecional packers like themida, armadillo, ASPack and others.

PS: I need to end coding polymorphic methamorph hiper super dual quantum bathroom (sounds very weird, but people think this way i am pro xD)

[zimbred]

ProtocolCore call Mix Proc, so you can hook your MixFunctions from DLL into Mix proc or ProtocolCore. Hook in protocol core is more effective, because you can intercept mix packet earlier than mix call - when you intercept mix packet you can jump to end ProtocolCore function without requirements of interpreting packet by GameServer functions.

I don't must test new classes and others Season 3 features on your server, because i test it on my own server :).

Anyway - This logical, that ASM is faster than C++, because ASM is low-level language, BUT code Windows, Office or Mu Emulator in ASM - this is the point for me ;] ;).

[Deathway]

C++ can be faster as ASM, it depend of your compiler

Now i MUST remark that less lines don't means Better perfomance, Registers in ASM were made for increase the speed, thats why many c++ compilers use it on its routines, playing with code like INC DWORD PTR DS[XXXXXXX] is for reduce the code , playing with INC EAX is related with Speed, however ASM can be faster i think

PD: some new compilers also Add an special feature related with Calling procedures, they avoid the classic PUSH , instead of that they reserve a space for the stack, adding the ESP value, and then they use the MOV instruction , this also increase even more the speed, at first look, this should look more "heavy", but it is faster

C++ can be faster as ASM, it depend of your compiler

Now i MUST remark that less lines don't means Better perfomance, Registers in ASM were made for increase the speed, thats why many c++ compilers use it own its routines, playint with code like INC DWORD PTR DS[XXXXXXX] is for reduce the code , playing with INC EAX is with Speed,

C++ its not made for playing with regist, in fact its oriented to playing with structured coding, has you put there its a very good example of structured, it can be reduced with ASM much more.

This is SSE scalar definition on VC++ compared with ASM:

VC++ vs assembler code and how to write floating point code using scalar SSE

A good document to see, more if some people think VC++ its superior on scalar fuctions SSEs fuctions and also it explain about FPUs.

I really wanted to learn c++ before. But it gets frustrating :S

omg, i saw "[Guide]Understanding Development of GameServer Files and Main.exe"
where is the guide?
