Tic Tac Toe Game

This is a tic tac toe game made using Python with PyGame for the game structure and Prolog to define the behavior of the actor that plays the game along with the user.

Dependencies

• PyGame >= 2.1.2
• PySwip >= 0.2.10
• SwiProlog >= 8.4.2

Installing Dependencies

On Linux, the dependencies can be installed with the following commands:

sudo apt update
sudo apt install swi-prolog python3-pygame python3-pip

Some python libraries should also be installed before running the software, it is recommended that you install and configure anaconda, and create a virtual environment to install the following dependencies inside:

conda create -n ttt python=3.10
conda install -n ttt -c conda-forge libstdcxx-ng
conda run -n ttt pip install pyswip==0.3.1
conda run -n ttt pip install pygame

If conda run -n ttt pip install pyswip==0.3.1 did not work you can try using conda run -n ttt pip install git+https://github.com/yuce/pyswip@master#egg=pyswi instead.

Executing the Program

After installing the dependencies (inside the conda env) execute the program with:

conda run -n ttt python3 main.py

Basic Debugging

For basic debugging there exists two basic debug levels:

1. Describes each action suggested at each move of the player

   DEBUG=1 python3 main.py

2. Describes eventual exceptions that occurred during the execution of the program (it also includes 1)

   DEBUG=2 python3 main.py
