Games: Supervised Score Tracker

Refactor your existing Games: Score Tracker module to be a named process and configure it with your Games Supervisor. Ensure your existing Games: Score Tracker test suite continue to pass. You may need to alter it slightly now that Games.ScoreTracker is a named process.

If you don’t already have a ScoreTracker module you can use the one below.

defmodule ScoreTracker do
  use GenServer

  def start_link(opts) do
    name = Keyword.get(opts, :name, __MODULE__)
    GenServer.start_link(__MODULE__, [], name: name)
  end

  def add(pid \\ __MODULE__, points) do
    GenServer.call(pid, {:add, points})
  end

  def get(pid \\ __MODULE__) do
    GenServer.call(pid, :get)
  end

  @impl true
  def init(_opts) do
    {:ok, 0}
  end

  @impl true
  def handle_call(:get, _from, state) do
    {:reply, state, state}
  end

  @impl true
  def handle_call({:add, points}, _from, state) do
    {:reply, state + points, state + points}
  end
end

Bonus: Track Scores

Whenever a player wins a round of Guessing Game, RockPaperScissors, or Wordle, increase the player’s score.

(Optional) Consider printing the current score every time you increment it to make debugging and visual display easier. (Optional) Each game can be worth the same amount of points, or you might vary the points depending on the game.

Bonus: Score Menu

In the previously implemented Games.Menu module, implement a Total Score option which prints the current total score. It should use the Games.ScoreTracker module to get the current score.

$ ./games
Select a game:
1. Guessing Game
2. Rock Paper Scissors
3. Wordle
4. Total Score
Select: 4
Your current session score: 3
