PyLoader (Python 2.7)

[maximus780]

Simple python loader for metin2 client(or any game) that uses Python 2.7 so that you can load your scripts and import modules offered by the game that means you can use functions the game exposed to it's scripting system(bindings).

I couldn't find working loader for 2.7 so here it is.



USAGE: Place PyLoader.mix in metin2 client directory, if you want to use it as .dll then just rename it.

There is no support for compiled python(*.pyc) files and no autoload function but I'm giving you the source code so you can add this yourself!

it works with small scripts but when I try to execute longer scripts the client crashes. Any idea for a solution? the other public pyloader (v2.7) have the same problem.

How many lines has your script that crashes the client?

I haven't experienced this issue yet. This could be either problem with python library or metin2 client.

700-1000 lines load just fine to me.

PyRun_SimpleFile is missing in most of clients like it's not exported

dumpbin output:

I want to load , I have a file which just imports the main script (hackbar). But this one imports about 20 other scripts. All in all there are thousands lines of code which have to be imported.

The Pythonloader from musicinstructor for python version 2.2 works fine:

I haven't checked your mod yet but I've checked pythonloader you mentioned and it uses PyRun_SimpleFile and PyRunSimpleString. Those functions are high level functions to low level python PyRun_File(more specifically PyRun_FileExFlags, PyParser_ASTFromFile) and PyRun_String(deeper PyRun_StringFlags and very low-level PyParser_ASTFromString) you can find them

Metin2 client bundles custom version of python27.dll which replaces PyModule_GetDict with PyForModule_GetActualDictionary and some Py_ForProgramAddActualName, this is just for confusion but it's exactly the same.

I've tried replacing PyRun_SimpleStringFlags with PyRun_File but the game closes, maybe memory is protected? I will let you know if I find more clues but I rarely find time for playing with games.

The logic behind loading python scripts from file:

m = PyImport_AddModule("__main__");
if (m == NULL)
return -1;
d = PyModule_GetDict(m);
.....
v = PyRun_FileExFlags(fp, filename, Py_file_input, d, d,
closeit, flags);

Attached my messy code lol with few different options.

Have fun

thats why my multihack crashes on some pserver i suppose

[maximus780]

123klo: please check this version if it crashes to you. I'm trying to mimic here m2 way of loading python scripts.

also check this script and run it with loader and see what happens:

filename = 'yourscript.py'

f = open(filename, 'r')
content = f.read()
# or exec(compile(content, filename, 'exec'));
exec(content);

I can't load Klo's multihack on Tsuyoshi2

Even not with the new experimental version

Please try updated one. It looks like in your client this function is not renamed. I have added a fallback for old one.

[MasterGamer1]

how do I type in the filename?



I swear to ***, you're my hero if you can make Klo123's bot work on that.

[maximus780]

Fixes crashes on 123klo's mod and probably in other scripts too. I will include the source code as soon as I refactor the code.

EDIT: I've got report, there was some problem where you couldn't insert commands for example on Metin2.SG. That's fixed already. See first post for an update.

You can type in the filename now. Download updated dll.

Still doesn't work on Tsuyoshi2



Edit: Maybe Klo123 could help on this as well. Would be AMAZING to see his great hack working again

try to open the file "syser.txt" of your metin2 client and post the content here. Anyway the latest m2kmod version wont work for 2.7 clients at the moment because they are only compiled for 2.2 client. But on 01.06 I will release an update for 2.7 and some other features.

the latest version of maximus780 works with m2kmod now (wait for the update next week)
