Free Prisoners

An application built on top of Free Monad in Cats. It shows how Free can be used to create pure DSLs, side-effecting interpreters and how to use those things together.

The example implements a way to play Prisoner's Dilemma in several modes:

• Hot Seat Game - two players play using one computer and console input/output,
• Single Player Game - one player plays against a bot,
• Multiplayer Game - one player plays against another player (or bot) on remote server.

Running local games

1. sbt "runMain com.michalplachta.freeprisoners.apps.HotSeatGame" - to run Hot Seat Game.
2. sbt "runMain com.michalplachta.freeprisoners.apps.SinglePlayerGame" - to run Single Player Game.

Running Multiplayer Game with the Remote Server

RemoteServerInterpreter uses Akka Remoting (codename Artery).

To run Multiplayer Game you will need three separate sbt sessions:

1. BIND_PORT=2552 sbt "runMain com.michalplachta.freeprisoners.apps.MultiplayerServer" - to run the server on specified server port,
2. sbt "runMain com.michalplachta.freeprisoners.apps.MultiplayerGame" - to run the first player session,
3. sbt "runMain com.michalplachta.freeprisoners.apps.MultiplayerGame" - to run the second player session.

See application.conf for more details about the configuration of all 3 actor systems.
