Battleships

This repository contains the code for playing a distributed game of Battleships using gRPC. It has a server component as well as a client component.

Client

The client contains a class which can be used to build a game client around. The main.py file contains a reference implementation just to show how that could be done.

Server

The server implementation is very loosely based on the Simon game, which can be found here: https://github.com/grpc-ecosystem/grpc-simon-says. However, that was written entirely in Go, while this is written in Python.

Game play

The game works like this:

1. A client first joins a game server, which then registers an open game;
2. A second client joins a game server, which joins an existing open game;
3. The game servers (one for each client) communicate using Redis (with the Game ID as the unique channel);
4. Clients play moves (i.e., attack a square) and report states (hit or miss), which are forwarded by the servers;
5. The game finishes when a client reports a 'defeat' (meaning Game Over).

Clients communicate with game servers using gRPC (a stream-stream connection). They send attacks and reports, and receive the result of their actions (hit/miss) and information about whose turn it is.
