Games: Supervised Score Tracker

You're going to setup your Games project as a supervised mix project.

Then, create a Games.ScoreTracker GenServer which will track a player score as they play different games.

Decide on point rewards for winning a game such as:

  • guessing game: 5 points
  • rock paper scissors: 10 points
  • wordle: 25 points

Increase the ScoreTracker's score whenever a user wins the game.

Requirements

  • The initial score tracker state should be 0.
  • Handle an asynchronous {:add_points, points} message to increment the score state.
  • Handle a synchronous :get_score message to retrieve the current score.
  • Games.ScoreTracker should be started as a named process by the supervisor.
  • Create the start_link/1, add_points/1, and current_score/1 functions as documented below.
  • Write a full suite of tests including at least the following cases:
    • "current_score/1 retrieves the current score"
    • "add_points/1 adds points to the score"
# Games.ScoreTracker should be a named process, so we don't need to provide the pid.
{:ok, _pid} = Games.ScoreTracker.start_link()
:ok = Games.ScoreTracker.add_points(10)
:ok = Games.ScoreTracker.add_points(10)
20 = Games.ScoreTracker.current_score()

Score Menu

Create a "score" command for the game menu that displays the user's current score. For example:

$ ./games
What game would you like to play?
1. Guessing Game
2. Rock Paper Scissors
3. Wordle

enter "stop" to exit
enter "score" to view your current score
