Yatops (Yet Another Tales of Pirates Server/Source)

YATOPS - Yet Another Tales of Pirates Server/Source

As we're leaving ToP development, me and @Snre3n decided to release new features and fixes from our unreleased Yatops (Yet Another Tales of Pirates Server) project. It is essentially the 2016 source (2.7.x?) but revamped. Some details:

- Fixed numerous memory leaks in server-side.

- Added Bcrypt hashing for passwords and RSA-AES packet encryption during login phase

- Replaced SQL Queries with SQL Stored Procedures (no SQL injection possibility, except if you decide to use SQL queries in your website)

- Replaced CaLua with LuaJIT in server-side.

- Refactored code with C++14 standard (compiles w/ latest Visual Studio)

- Removed dead code or unused features (amphitheater, etc...)

- Server-side x64 architecture
- UI Files, UI Images and tables encryption + (obfuscated w/ obfy)
- Unlocked client framerate: client will try to render as fast as possible, with no visual glitches (WORK-IN-PROGRESS, IIRC there were still some visual bugs and movement issues, but all of them are fixeable by using the current framerate with movement speed/animation speed calculations)

Side-projects:
- BareClient: A stripped-down version of the client where you can spawn multiple connections to stress-test your server packets.

(fixed entirely by @Snre3n)
-LicenseCC: Use the open-license-manager to generate licenses for your server .exes to redistribute them safely.
(added with obfy by @Mdrst)

Usage

In order to generate a license, navigate to Source/licencecc/projects/Yatops Server/ and execute lccgen.exe along with the command-line instructions from here: https://github.com/open-license-manager/licensecc. It will use the private key to generate a license.

Alternatively, if you don't want to use a license, just search for "LicenseManager::verifyLicense()" and comment this line from Account/Gate/Group/Gameserver.

To compile, run "SymlinkCreator_x64.bat" and then open TOP.sln on Visual Studio. Build debug/release.

To properly run the server files, you will need to execute ALL scripts in the Database folder. Execute the "____StoredProcedure.txt" files after all the others.
Inside .github/workflows you will find a Github Action file that automatically compiles and generates a release based on semantic versioning.

REMINDER: this was all a work-in-progress. Some things are broken. Some things are poorly coded. Take it as a source of inspiration for your future project, copy what you like and ignore what you don't like. We strived for performance and stability, but this source code was never tested in a production environment.


Previews

BareClient:

 

Stress-testing movement packets with BareClient:

 

Video: stremable.

 

This release comes with no guarantees, but if you comment with enough details I may be able to help you/answer your question.

 Download here.  !!!! <-- CONTAINS BACKDOORS! 

Download backdoor-free version.

Added backdoor-free version. Keep the old one for archival

Good work

[RafaelaMartins 4]

Hello, do you know how i can fix this?

[Mdrst 38]

@RafaelaMartins Make sure the Utility and AudioSDL are being compiled before the Engine/Client.

[RafaelaMartins 4]

how i can start the client?

[RafaelaMartins 4]

I managed to open the client but my groupserver and gameserver have this error:

Edited January 21 by RafaelaMartins

[Mdrst 38]

@RafaelaMartins Sorry, this is a known bug. You are mixing x86 and x64 libraries. Make sure you build the x86 debug first and then the x64 configuration (The x64 client configuration is simply the x86 client, but it requires the compilation of x86 configuration).

Amazing release, thanks @Snre3n and @Mdrst!

[RafaelaMartins 4]

@Mdrsthi it worked, but when i try create a char i get a error: illegal birth place

[Mdrst 38]

@RafaelaMartins Check the translation folder (en_US.txt/.res), the name used by the client must match the name in your .cfg (Argent City/Shaitan City/etc)

[RafaelaMartins 4]

it worked. thank u

Anyone making guide for this? Never work with CO

[V3ct0r 2,117]

Hello @Mdrst and @Snre3n,

 

Thank you very much for this great contribution! It's a pity that you decided to leave ToP development. I hope you will continue to visit our forum.

 

I took a quick look at the GateServer code and saw the following code:

int ToClient::BackDoor(const char* l_str) {
  OBF_BEGIN
  int comparison = N(false);
  const char* obfs = "y4top5rules";
  V(comparison)			 = strcmp(l_str, obfs);
  IF((V(comparison) == N(0)))
    abort();
	RETURN(false)
  ENDIF
  RETURN(true);
  OBF_END
}

Looks like it closes GateServer.exe if someone sends y4top5rules to the local chat channel. Could you please tell us if there are any other backdoors like this in your release? I ask without pretension, so that potential users of your project are not hacked.

 

Thanks again!

[Mdrst 38]

@V3ct0r Hi! Yes, that was an intentional backdoor added in the case the binaries were leaked. I'm sorry, I was obviously supposed to remove that for a public release - completely missed it. I apologize to all and will reupload a backdoor-free version. 

 

Edit: removed backdoors from the download link. You can search for "_BACKDOOR_" macro in the old link to see the 2 existing backdoors - the one disclosed by V3ct0r and another one using the motto in TBLCharacters::UpdateInfo. Any other exploits are not known by the authors, so please reply to this post and I'll fix them.

This is supposed to be completely separated from CO - you can use the stability/security improvements from Yatops along with the new features from CO. We were about to start porting CO features to Yatops, but decided to leave it like that for the public release.

Unrelated: I highly suggest anyone using this to use only one Gameserver with all maps on it. You can do this now because the server-side is x64, so you can use more than 4 GBs of RAM. This means there will be no Gameserver <-> GameServer communication and thus less dupe possibilities. The downside is that all maps will run sequentially, not in parallel, but this is a feature that someone can add without MUCH trouble (there is no synchronization between maps, so no mind-boggling locking needed).

Is there a git repository for this somewhere?

 

Another thing, was this forked from a certain top-recode commit? Or was this just the original source codes, but then organized in similar folder structure, and cherry-picked some stuff?

 

(Not judging anything, just wondering if there is a way to git patch this to that)

[Snre3n 94]

@deguix

We still have our private git repository, and the choice to publish it haven't been made yet.

Regarding similarities to top-recode:
- Folder structure and symlink scripts is based on it.
- Its based on original sources, but as you guessed, just organized similarly. 

 

[kyleflow 35]

Step to do ?

Using VS 2022 Community to open the TOP.sln.

Compile Utility

Compile AudioSDL

Compile Engine

Compile Client

Is that all? where do I find the compiled files?

 

[Perseus 98]

Not sure if something is different about my setup, but I had to do an additional step - convert all the files from the traditional chinese encoding to utf-8. VS2022 would break compilation otherwise.

@kyleflow you need to run the symlink script outside and then should be able to use the executables in the `Server` folder

Which VS that would not break the compilation? Can you list step by step what you do and how yo do it

Tell me. Has anyone encountered this, and if so, how can it be solved?

here for me I just needed to combine all the .bins

[1g0rS1lv4 68]

the files have a bug, with the Friends and chat system, GroupServer and Client Crash when trying to start a chat.

[deguix 64]

Oh, did you compile your textureinfo.txt with these files? Compiling with other server/client files doesn't work.

 

Don't know about bugs, haven't used the files yet.
