##TicTacToe in Ruby
This is a game of Tic-Tac-Toe aka Noughts and Crosses, built in the Ruby language. If you would like to read more on the rules of this game: Wikipedia
I built this game with the following restrictions:
- Playable in 3 modes:
- Human VS Human
- Human VS Computer
- Computer VS Computer
- When playing against the computer, the computer must never lose
- The user should also have the choice of which player goes first.
Challenges & Learning Outcomes
I really enjoyed the whole project all the way from the paper sketches to passing the tests.
I found this a bit more complex that I would have imagined before starting it. The complexity that I came across was mainly dealing with the AI (Computer player).
It was easy to get the computer to make a random move but then getting the algorithm right to make the "best" move took some time. I realised that I was approaching the problem from a messy angle and that caused the delays. I then came across the MINIMAX Algorithm after researching the matter extensively. This took me quite a while to understand and apply properly. After hours and hours, I managed to successfully implement the algorithm and plug it into the Game.
I found it was a better approach to place all the Game rules in front of me and then write up the pseudo-code for it, bearing in mind the "best" moves.
I used the
guard gem for this project, which I haven't used in a while. This really helped with the TDD aspect.
I also realised that when I got to completing the first Version (Human vs Human), the red-green-refactor cycle became a bit messy. This is something I aim to work on for the next project.
What helped me quite a lot throughout this project was to constantly play the Tic-tac-toe game against myself in order to visualise the "best" moves.
- Test the MINIMAX properly
- Clean up the runner file
- Seperate the CLI code from the business logic
- Make a Web app version with Sinatra/Rails
- Make the Command line version look nicer
- Use a game engine such as Gosu
- Make this into a Gem
