[RELEASE] Source library for add functions to game

[Niks90]

THAT SOURCE IS NOT COPYRIGHTED, IS NOT A YMIR WORK, SO DONT DELETE MY THREAD!!!!

As the first topic has been closed without a valid reason by a moderator, now i re-post that source.


Hello guys, this release is targeted to publish the source code of the infamous library for editing
and the addition of features to the game file. The source code is quite simple, there is a main that has the task of loading
and initialize the modules (which will contain the code changes to the server) and there are folders containing utility
and some functions already written. This library contains an example the addition of a function of quests
has the task of query through lua (using directly the functions of the server, so no unnecessary
lua modules and scripts pataccosi), which I called "sql.query()" and another function that its role is to apply
files "dif" directly at server startup, in memory (hotpatch), without actually changing the executable itself.

USE:
The example functions are two as I said. For "sql.query()" i'll write some example for explain is at best.

The query is performed trivially by passing it as an argument to the function.
Example:
sql.query("UPDATE table SET a = b WHERE c = d ;")

If the query does not return values (UPDATE, DROP, etc ...), then there is no problem, but if I were to get interest
one or more values returned from query, how do you make that?
Example:
local my_query = sql.query("SELECT a, b, c, d FROM table WHERE a = b ;")

Nothing could be easier! We have a variable my_query, that my function "fills" as if it were a lua table.
So you must return name_of_variable.column_selected: my_query.a
Simple, no?

With regard to differ on the fly instead, as you can see in the main there is a way, but what does it represent? Is the path
the folder that contains the dif be applied when the server starts. Instead of the one present at the time, it can be
use any path, but since he is "the same" for each game, if the folders that contain the game are not symmetrical
to the folder that contains the dif advice to put a static route (Example "/usr/user/my_dif_folder/").
In this folder, you must create a file called "dif.cfg" which will contain in order (one per line) the names of the files
loaded, which must be in the same folder.

Example:
file1.dif
file2.dif
# File3.dif ---> yes, putting a # in front of the name of the file will not load!
...
filen.dif

For convenience, it is best that the dif files contain only the offset and bytes to patch (without header created by ida and without various comments in the file).

HOW TO FILL:
Make sure you have gcc installed on the server, place a terminal in the source directory and run the command "./compile.sh"
(if it says that you can not run, it is likely that the missing execute permissions, assign them with a "chmod + x compile.sh" and then fed back the compile command).
This will create a new file in the folder above where the source, called "royalsword.so", this is your library.

HOW TO START WITH THE LIB:
To make it load to the server, just change the script you use to start different game, changing the line
Run the game (eg "./path/to/my/game") with:
LD_PRELOAD = "/path/to/my/lib/royalsword.so" ./Path/to/my/game
Obviously, for a server with multiple cores, you need to edit each line where a core is loaded.

So what the hell this does ? I must write code in C++ and then save it and i can add functions to the game core or what ?

There is no need of reuploading it.
I reported your post

[*Casi*]

Thx

[JachuPL]

sooo, if i know C/C++ i can write my own functions and recompile it using your stuff, right?

yes

not nice source

[Sphinx²]

Hmm.... It's bad(wrong?) to release the method for hooking functions in the game...
Now every idiot can do that...

Kind regards

ich versteh nur bhf

Edit: liegt nicht an meinem Englisch

mit den sachen hier kannst du quasi alles zur game an funktionen hinzufügen was du willst und wie du lustig bist, so im klartext so das hier ist ein beispiel so wie ich das verstehe.

Aber die methode ist auch nicht ganz so neu eig musste man nur hier in den threads rumschauen es wurden immer hinweise gegebene wie es funktioniert, naja jetzt weis es jeder nur noch ein hindernis gibt es nicht jeder kann C++ :P ( ich bin am lernen ).

zum thread:
Nice thread very good, thanks bro
