man.battleships 🚢

Your task is to implement a Bot to play a game of Battleships!

In a game of battleships, each player has a 10 x 10 board on which they place 5 different types of ship.

The aim of the game is to shoot all of your opponents ships before they shoot yours.

Getting started

After cloning this repo, to get started, run:

python -m venv virtualenv (optional but recommended)

source virtualenv/bin/activate

pip install -r requirements.txt

To implement your bot, your team must submit an implementation of Bot which overrides the place_ships and get_shot methods. You can see examples of implemented bots under man.battleships/bots. SampleBot.py is a good place to start.

Game structure

Within each game between two bots, the following happens:

  • Player 1 places their ships
  • Player 2 places their ships
  • Player 1/2 take alternating turns to shoot positions on the board of their opponent.
  • After each shot, your bot will receive a dict of information indicating whether the last shot hit / missed an enemy ship, sunk an enemy ship, and if so, which ship it was, or an exception if the shot failed for some reason.
  • The game ends when either player has 'sunk' all of their opponents ships

Testing your bot

Command line

In order to test your bots, we have provided a script allowing you to play n games between two Bots p1 and p2 present in the bots directory. The usage of this script is as follows:

python play_game -n [100] <p1> <p2>

Here, p1 and p2 are the string class names of the bots you wish to test.

Visualising games

Alternatively, you may wish to visualise games between two bots. To run the game visualiser and backend, run:

./run_all.sh (or run_all.bat on windows)

You can then navigate to localhost:8000 to play a game between any of the bots present in man.battleships/bots

Rules

  • Your bot gets a maximum of 3 retries for placing ships in each game and making shots on each turn. If after these retries you fail to return valid ship placements / a valid shot, you either lose the game or lose the chance to make a shot that round

  • The maximum time allowed to compute place_ships and get_shot each round is 100ms. After this time, your move will time out and you will lose either the game (if place_ships has timed out) or the chance to make a shot that round (if get_shot has timed out)

  • Please play nicely! any obvious attempts to break the game engine will be disqualified

Submitting your bot

In order to submit your bot, simply make a pull request to man.battleships containing your implemented Bot in the man.battleships/bots directory . Ensure that your Python file and implemented Bot class have the same name.

Good Luck!
