[help] Understading Mt2 function calls

Hello pvpers,

I've been investigating this for a while now and I feel that I've come to a brick wall therefore I'd like to request your help.

I've done a cpp DLL that calls a python script as soon as it is injected into the metin2 client.

I've successfully printed some messages in the chat with using the chat import.

But I've not been successful with any other function.

This is a basic example that print in the chat a message but blows up afterwards:

Code:

chat = __import__("XXsRHxy")
chr = __import__("chr")

chat.AppendChat(7, "test")

for i in xrange(100000):
    if(chr.HasInstance(i) != 0):
        if(chr.GetInstanceType(i) == 6):
            chr.SelectInstance(i);
            chat.AppendChat(7, str(i));

I get a "test" written to the chat, but then it blows up, before anyone asks, there are no printed logs I've tried to catch the error on the cpp side and check for

Code:

    
if (PyErr_Occurred())
        PyErr_Print();

but I have nothing printed out in the logs, if there is a python error usually it prints out something.

I wanted to do a simple scan for other players and in the future interact with them. Any suggestion is appreciated

I think it's not relevant but here is the cpp code:

Code:

#include "pch.h"
#include <Python.h>
#include <thread>
#include <iostream>
#include <vector>


bool executePythonFile(const char* file) {
    int result = 0;
    char path[256] = { 0 };
    strcat_s(path, file);
    printf("Executing Python file: %s\n", path);

    PyObject* PyFileObject = PyFile_FromString(path, (char*)"r");
    if (PyFileObject == NULL) {
        printf("%s  is not a File!\n", path);
        goto error_code;
    }
    result = PyRun_SimpleFileEx(PyFile_AsFile(PyFileObject), "MyFile", 1);
    if (result == -1) {
        printf("Error executing python script!\n");
        goto error_code;
    }
    else {
        printf("Python script execution complete!\n");
        Py_DECREF(PyFileObject);
        return true;
    }

    if (PyErr_Occurred())
        PyErr_Print();

error_code:
    PyErr_Print();
    Py_DECREF(PyFileObject);
    return 0;
}


void init() {

    AllocConsole();
    freopen_s((FILE**)stdout, "CONOUT$", "w", stdout);
    std::cout << "### START ###" << std::endl;
    
    executePythonFile("C:\\code\\testing.py");
 
    FreeConsole();
}

BOOL APIENTRY DllMain(HMODULE hModule,
    DWORD  ul_reason_for_call,
    LPVOID lpReserved
)
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH: {
        // sdk::utilities::h_module = (HMODULE)hDllHandle;
        init();
        FreeLibraryAndExitThread(hModule, 0);
    }break;
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}
