A simple connect four game written in Python. There is no fancy GUI, just a CLI interface. This is more of a connect four library, really, although there is an executable application with which one can play human v. human, human v. computer, or computer v. computer matches.
Run
> ./connectfour.py
to get a help message indicating how to run the game.
The motivation for this project was to create a sandbox for writing machine learning algorithms to try to make a robust AI opponent. Write your own AI modules and test them against one another, or against yourself. Connect four is a simple game, so it seemed like a reasonable thing to play around with.
This software is released under GPLv3.
Just Python and Numpy.
connectfour.py - The connect four game. Provides a function call so
you can run the game from your own application (e.g. you want to write a
script to have the computer play itself a bunch of times) or run from
the command line to use as an application for playing PvP.
board.py - Contains the Board class, which is the basic object for
connect four gameplay. This object encodes the rules for connect four,
and stores the current game state. It also contains methods for dealing
with unique integer IDs describing the current game state. Convert
between a board array object or its associated ID, which might be more
useful for e.g. storing in a database.
c4bot.py - Connect four player objects. This includes AI players and
human players. The basic human player just asks for input from the
command line as of now. A C4Bot object just knows what player it is, and
contains the logic for making a move given a board object. Make a child
of C4Bot if you want to write your own AI opponent.
init_db.py - Initializes an SQLite database for storing information
about board configurations.
trainer.py - A script for having the computer play itself and "learn"
a good strategy. Feeds the database setup by init_db.py.
fight.py - A script to have the computer play itself a bunch of times
and report how many times player 1 was victorious.
