[General] Emulating?

Hello, I was just wondering how i would go about learning how to copy a game. For instant : People are making Silkroad servers, Were do they start? How do they get the files or what ever. I would spend all of my time doing this (Making servers etc) if i knew how to copy a game. It would be just great.

Heres what i want to know :


What programming language do i need to know? -

What programs do i need? -

Were can i get the infomation to learn about this? -

Were do i start to make a game project? -

(Let me re-phrase what i said erlier. I want to make a game. Example : Silkroad. How do you start making your very own one? - Like make your own server files.)

Making the client or making the server is quite different.

Server is the easiest of both, but stuff can get complex. It is likely it will take you atleast 3 years before you can code it quickly and good.

Most games use C++ as their language of choice, if you want to rewrite server code, you can choose whatever language you like as long as it supports connections and can handle them.

C# for instance is much easier to develop in. C++ though is more efficient, which has a pay off -> slow development.

You'll need an IDE (an program to easily compile your sources and write sources with). This can be VC++, DevC++, Code::Blocks (I use) for C++.

For information, check the internet. Loads of tutorials ;).


Making a whole game tbh, is not going to work for you within like 5 years. Developing WoW for instance, costs millions of dollars and big development teams...

Making server files is easier, you don't need content like 3D tree's or character animations. This makes it programming only, which can be done alone for small games.

Thanks for that infomation, The thing i am saying is people are making Silkroad servers at the moment. How are they doing that? Like.. Were do u get the codes from etc..

-TheSaint

They are not copying, they are emulating.

Its just a title dude, Im not implying that. I am seeking for infomation not newbs trying to get there post count up.


Would visual basics 6 be any good for this type of work. A person who is making a silkroad server is using it and im just wondering is it effective as the rest?

He's right, it's not copying.

VB is not meant for servers. It would be foolish to develop servers with VB, VB is made for business apps (quick GUI creation, quick development, slow speed). I suggest using C++ or C# as your language of choice for servers.

I downloaded codeblocks gonna give that a try. I dont know how it will go but its worth giving it a try

-TheSaint

Also take notice of the fact, that you don't make programs in codeblocks, you write programs in it. It's not anything like VB where it's simple drag&drop. You need to know C++ (Or any other programming language it supports) before you can do anything with it.

I am going to learn C++ hopefully. Errm i know VB is drag and drop but i was just asking the question could i use it and i got my awnser, Thanks. Errm in this Codeblocks i put
// my first program in C++

#include <iostream>
using namespace std;

int main ()
{
cout << "Hello World!";
return 0;
}

Its just basic code for Hello World, I press Build & Run and it gives this at the bottom @

"TheSaint1 - Release" uses an invalid compiler. Skipping...
Nothing to be done.


- I used console application

-TheSaint

if you wanna emulate a mmo serverr the first thing you need to do is to break the encryption
if you actually managed to do this you can think about implementing a server
it musnt be c++
java/python/asm whatever will also do
it just depends on how good you plan your classes and optimize it :)

So i must not use C++ ?
I must learn how to De-Crypt
I must learn a diff language?

-TheSaint

(I just wana hopefuly develope some server files like SREmu maybe?)

Evill33t meant: "it needn't be c++". Miscommunication.

Yeah, you don't HAVE to learn C++ for server development. But if you want to continue developing in future, you should learn C++. It's the most used language at the moment, and with that knowledge you can easily switch to C# for instance.

As for the compiler: you need to install one. MingW is a very decent one for Win32.

Read this: MinGW installation - CodeBlocks

wrong
.net and java are the most used languages atm
compare
Compare Languages - Ohloh
and see how c++ is going down
so if you wanna be safe for the future learn c# or java :)

ps: mingw is one of the worst compilers for w32
the intel one is imho the best but the ms compiler also beat mingw by far
(same on *nix plattforms gcc sucks, use intel if you can afford it)

Eww, .net. :sad: Every language invented by microsoft makes me want to go sit in a corner.

sorry but if you dont understand the basics of server/client communication and encryption/decryption you should start with the basics - a good book :)

.net isnt so bad, but well i also prefer other languages.
My point is just that in a few years c++ will be used for 3d engines and operating systems only(and even os development switches to other languages) and what about D ? its not so bad either ^_^

If i may , i'll just jump in here and ask if you have any good examples of the books that would be required.

Thanks alot there mate ;)

for breaking the packet encryption:
Cryptanalysis - Wikipedia, the free encyclopedia
Packet Hacking & Following Encryption

some asm knowledge is helpfull, best is to get the encryption out of the client (second link) instead of analyzing the traffic (first link)

Ps: i might someday join ragescape development a bit since i checked the runescape stuff with jad a while back and saw some things that could be replaced/improved :P


psps:
imho and according to my asm wizards:
OllyDbg v1.10
the best disasm :)

pspsps:
Home Page of Jad - the fast Java decompiler
for decompiling java apps ;)

You have alot of knowledge evill33t , im sure you would be taken on with open arms, although im not sure how the development is coming, as i am preparing for my exams, which start tomorrow 0.o

Just collecting resources for summer xD

I meant for games, and other software that is focused on performance.

Sure, .NET and Java is great for quick development, and on the newer and quicker processors you barely notice the speed difference, but once you run several C# programs along eachother, you WILL notice the overhead.

Ohloh: If you tick C++ only or C only, its rising quickly. But once you tick C/C++, its decreasing quickly. Those graphs are controversion, can hardly trust them.

And yes, learning multiple languages is always prefered, C# seems to be getting popular but its windows only.

Java...too problematic, will never really become popular language.

C and C++ will exist for a loooong time, especially for linux environments. And since you'll want to build a server for linux/BSD (atleast, I would never build a server for windows) C++ is prefered.

c# is no problem with linux - mono works quite well i have industrie proven experience with it
and java is hell popular,whats problematic about it ? since 1.2 performance is increasing rapidly and on most tasks its on pair with c++

its a urban myth that c++ is super fast, c++ is unsecure and when you dont use inline asm its not much faster then standard c#/java

how about a little competition
u choose a mathematical problem/i choose one
you implement in c++ / i in java
and i bet that in the end i will be nearly the same or maybe even faster in java :)


if you dont trust me google for c++/java benchmarks java 1.5+
Stefan Krause.blog() Blog Archive Java vs. C benchmark #2: JET, harmony and GCJ
here is just one
mingw/gcc is nearly on every benchmark slower then gcj or even a vm driven java:P (and the vm can be optimized much further and gonna outperform gcj/iic after a while through hotspot compiling)

another one
C++ vs Java

and another one
The Java Faster than C++ Benchmark (ok this one is biased :P)

i could go on for hours....

and i do :P
Irrlicht3d.org*-*C++ vs. Java 1.6 - A fair Benchmark
from a c++ developer
keep in mind that with gcj or jet the java results would get MUCH faster

- i gonna keep updating my posts here to proove once and for all (at least to rz) that c++ = fast / java= slow is not valid since at least 3 years

ps: for multiplattform java is the best choice thats what it was made for
c++ is ugly to port (posix vs win32) but i guess u use mingw AND mingw has such bad performance that i gonna easily outperformance you :P

psps: about your games remark, ncsoft is coding a next gen mmog as we speak in java, yes even the client
Home - jmonkeyengine.com
beat that a fast 3d engine with opengl in a vm that works on EVERY plattform (you could port it easily to OpenGl/Es and Micro Plattform and run in a psp for example)
besides you ever noticed that nearly every cellphone game is coded in java with opengl/es and we talk about embedded plattforms where overhead for the vm is much more critical then on a standard pc


pspsps:
and another one
CIO - Blog: Linus Torvalds: Why C++ Sucks
Linus Torvalds: Why C++ sucks
""It's made more horrible by the fact that a lot of substandard programmers use it, to the point where it's much much easier to generate total and utter crap with it. Quite frankly, even if the choice of C were to do nothing but keep the C++ programmers out, that in itself would be a huge reason to use C.""
so stay at ansi c if you talk about linux/bsd development ;)

sorry but the remark that java never gonna be popular made me freak out :P
TIOBE Software: The Coding Standards Company
here another one
java is by far the most popular language atm

I'm not trying to some kind attack you with that, only made a correction.

VB is worst language for emulating as far as I know, it's slow, very. VB is for RAD. You need C++ or Assambler.

Peace bro.

omg
get your facts straight guys
c++ isnt as good as you all think
if you want performance go for C
noone codes in assembler nowadays o.O
and again Java and C# can stay up with c++ without problems
i am here to compete with anyone that feels like proving me wrong (i gonna use jet6 or gcj)
so whos up for the challenge ?
