m5n's Introduction

M5N

A simple swap2-based gomoku server/broker, written in C#, compatible with CPython 3.11

Requirement

Compiling

.NET SDK 8.0 or above
GCC (MinGW on Windows)
CPython 3.11

Runtime

CPython 3.11 (Only with python backend.)

Ruleset

Each player can do:

dye : Choose colour
put : Put stone

Let player A, B.

A put 3-times.
B choose:
1. B dye.
2. B put 2-times. A dye.
Continue with gomoku-ruleset.

Disclaimer

Virtual-environment or such things are not supported.
set_colour, set_stone, choose_colour, place_stone, make_decision, victory, defeat is reserved function/handler.
- Do not rename these functions.
- Do not change function signature. Or may cause the client to crash.
Only tested on pure python (without any packages)

How to write client

See working sample code with python. You can prove application manually with sample-code!

...or you can use C/C++ with same constants: See sample code with C++.

How to run client

Let your (python) source codes are in ./app folder.

Then, you can run client by:

M5N.Slave <endpoint> Python ./app <module>

M5N also supports native-backend built into dll/so. To use native-backend, Use below command:

M5N.Slave <endpoint> C path/to/your/binary.dll

These syntax is mnemonic with a below rule:

M5N.Slave <endpoint> <engine> [<engine-option>+] <module>

How to run server

M5N.Master <port>

Server will be listening on specified port number.

Client(임의로 작성한 테스트용 코드)

def place_stone():
    print("place_stone")

    global my_map
    seq = sequence_check()
    if seq == 0:
        x, y = 7, 7
    else:
        temp_map = copy.deepcopy(my_map)

        x, y = computer(N, temp_map, my_colour)
        if my_map[x][y] != 0:
            x, y = random.randint(0, 14), random.randint(0, 14)

    print("put: ", x, y)

    return x, y

그냥 랜덤값 출력하게끔 하면 문제 없이 잘 돌아가지만 AI를 넣고 돌리면

Unhandled exception. Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'M5N.Interop.Python.PythonInteropModule'` does not contain a definition for 'PlaceStone'

이 오류가 뜹니다

compute 알고리즘이 문제가 있다면 x,y 값이 비정상적이어야 한다고 생각이 드는데
print("put: ", x, y)에 x,y값이 제대로 들어갔는데 안 되는 이유가 뭘까요?
자꾸PythonInteropModule에 PlaceStone이 포함되어 있지 않다는 오류가 뜨네요.. 뭔가 고려할 점이 있을까요?

기타사항

checking computer...
movePoints: 6 7 부분은 AI 내에서 체크용으로 박아둔 print 부분이고
최종적으로 compute 함수가 잘 돌아가는 지 체크하기 위해 다음과 같이 put 프린트를 사용함.
참고로 중복된 값을 compute가 반환하지는 않았음
하드코딩으로 박아 둔 7 7은 작동하지만, compute 함수에서 주변 노드를 탐색한 후 6, 7 stone을 반환하면 오류가 발생함, 다만 원인을 모르겠음
