Simple Tic Toc Toe

This project is a simple tic toc toe game using Finite State Machine

---

Tic Tac Toe -

This is a game normally played with paper and pencil and often called noughts and crosses. The game is played on a 9-box grid and each player selects their mark as X or O They take turns placing their mark in one of the 9 boxes and the first to achieve three in a row wins. Three in a row can be hirizontal, vertical or diagonal. Its common that no-one wins and that is a Tie game.

Supports 2 players Supports 2 levels of difficulty for computer opponent =======

Instructions

python src/run_script.py

TESTS

make test

Design

Instead of a game loop, just for fun the implementation uses a finite state machine to switch between player turns. StartState -> TurnState -> EndState ->StartState

Next Steps

Change the display to use Raspberry Pi SenseHat and txt output - Done Change the display to use tkinter Add db to provide high score history

Running Instructions

Warning

I used pyenv 3.9.0, this takes 20mins to recompile during installation on raspberryPi 3. It required sudo apt-get install python-scipy sudo apt update sudo apt install libatlas-base-dev sudo apt install libopenjp2-7 sense-hat pip install sense-hat rtimulib

python src/run_scripts.py

Sensehat installation

1. Buy a sense hat and plug it into the raspberry pi when its switched off
2. Update raspberry pi O/S sudu apt update
3. install sense hat sudo apt install sense-hat
4. reboot sudo reboot
5. Sense hat examples can be found here '/usr/src/sense-hat/examples'
6. More sensehat info https://pythonhosted.org/sense-hat/

Environment

Upgraded to python 3.9.0 because tk would not work with earlier versions Sense hat didn't work with 3.9.0, install RTIMULib manually to fix this git clone https://github.com/RPi-Distro/RTIMULib Follow README.md on building and installing it
