# Mastermind Project
Check out my command line version of the game [Mastermind](https://en.wikipedia.org/wiki/Mastermind_(board_game)) built with Ruby!
This is a project from [The Odin Project](https://www.theodinproject.com/courses/ruby-programming/lessons/oop).
## Installation
Open your Terminal/Command Line. Navigate to the directory where your version will live. Type in the following:
```
$ git clone https://github.com/JonathanYiv/mastermind.git
$ cd mastermind
$ bundle install
$ ruby mastermind.rb
```
## Pre-Project Thoughts
I will need to figure out how to colorize the command line from a ruby script.
### Thoughts on Structure
```ruby
class Mastermind
instance variables:
gameboard
methods:
initialize: takes a parameter to decide whether human/computer picks the code
play: starts the game
instructions: prints the instructions
class GameBoard = one instance
instance variables:
solution as a colorcode object
array of colorcode objects for display
array of hint objects for display
methods:
display: displays the entire board
refresh: given a new colorcode, adds it to the display, and evaluates the hints
evalute: based on the colorcode, provide a hint
class ColorCode = instances include a solution instance and a guess instance
instance variables:
color1
color2
color3
color4
methods:
initialize: takes four parameters to create a set of colors or defaults to a randomly selected set of color
class Hint = instances of the hints with red/white/black
instance variables:
color1
color2
color3
color4
methods:
initialize: takes five parameters (including the colorcode solution) and sets its four colors accordingly
class Computer
instance variables:
included colors
methods:
algorithms to solve mastermind
```
## Post-Project Thoughts
1. To include color in the project, I found the ruby gem "colorize." I also read about ANSI Escape Codes [(see below)](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors) which were a little too intense for the scope of this project. See below.
```ruby
class String
def black; "\e[30m#{self}\e[0m" end
def red; "\e[31m#{self}\e[0m" end
def green; "\e[32m#{self}\e[0m" end
def brown; "\e[33m#{self}\e[0m" end
def blue; "\e[34m#{self}\e[0m" end
def magenta; "\e[35m#{self}\e[0m" end
def cyan; "\e[36m#{self}\e[0m" end
def gray; "\e[37m#{self}\e[0m" end
def bg_black; "\e[40m#{self}\e[0m" end
def bg_red; "\e[41m#{self}\e[0m" end
def bg_green; "\e[42m#{self}\e[0m" end
def bg_brown; "\e[43m#{self}\e[0m" end
def bg_blue; "\e[44m#{self}\e[0m" end
def bg_magenta; "\e[45m#{self}\e[0m" end
def bg_cyan; "\e[46m#{self}\e[0m" end
def bg_gray; "\e[47m#{self}\e[0m" end
end
```
2. The computer AI was rather complex to implement; I spent the most time on that portion specifically. I only managed to get it to a 20% win-rate for now. I will come back and update it later with the [wikipedia supplied algorithm](https://en.wikipedia.org/wiki/Mastermind_(board_game)#Five-guess_algorithm) that guarantees a solution in five moves.
3. My last project, [Tic-Tac-Toe](https://github.com/JonathanYiv/tic-tac-toe) followed poor practices regarding separating classes into different files. This project does better in that regard. However, several methods are overly complex and have too much responsibi
4. @benjaminapetersen and the Odinites found three issues.
1. The text sanitizer only ran each check once, so if you passed the first test but failed the second test, it would only check for the second test onwards. I fixed it by pulling it all into a large loop with redo statements if tests fail.
2. The project requires the gem 'colorize' which I had not previously set up for users, causing an error. I set up a Gemfile and added an instruction with bundler in the installation instructions.
3. Ruby has a syntax of two spaces per indent. I adjusted my text editor's settings to reflect this, so all future ruby files will be indented accordingly.
5. Overall, it was a very fun project, probably the most complex for me to date.
