Mastermind
Command line interface game I built during a prep course I took for App Academy. Built this in early 2016 when I had just started to learn programming.
- There are six different peg colors:
- Red
- Green
- Blue
- Yellow
- Orange
- Purple
- The computer will select a random code of four pegs. (Duplicate colors are allowed.)
- The user gets ten turns to guess the code.
- You decide how the user inputs his guess (maybe like so: "RGBY" for red-green-blue-yellow)
- The computer should tell the player how many exact matches (right color in right spot) and near matches (right color, wrong spot) he or she has.
- The game ends when the user guesses the code, or is out of turns.
Suggestions
I wrote a Code and a Game class. My Code class represented a
sequence of four pegs. The Game kept track of how many turns has
passed, the correct Code, prompt the user for input.
I wrote a Code::random class method which builds a Code instance
with random peg colors. I also wrote a Code::parse(input) method
that took a user input string like "RGBY" and built a Code
object. I made code objects for both (1) the secret code and (2) the
user's guess of the code. I wrote methods like
Code#exact_matches(other_code) and Code#near_matches(other_code) to
handle comparisons.
