Islands Text Client

Text client for the Game of Islands.

It’s a game for two players, and each player has a board, which consists of a grid of one hundred squares. The grid is labeled with the numbers 1 through 10 across the top for the columns and down the left side for the rows. Each square is named by its coordinates of the form (row, column).

The players cannot see each other’s boards.

The players have matching sets of islands of various shapes and sizes, which they place on their own boards. The players can move the islands around as much as they like until they say that they are set. After that, the islands must stay where they are for the rest of the game.

Once both players have set their islands, they take turns guessing squares on their opponent’s board, trying to find the islands. For every correct guess, we plant a palm tree on the island at that square. When all the squares for an island have palm trees, the island is forested.

The first player to forest all of her opponent’s islands is the winner.

Usage

To play the Game of Islands, clone islands_engine from GitHub and compile it:

• git clone https://github.com/RaymondLoranger/islands_engine
• cd islands_engine
• mix deps.get
• mix compile

Then, clone islands_text_client from GitHub and compile it:

• git clone https://github.com/RaymondLoranger/islands_text_client
• cd islands_text_client
• mix deps.get
• mix compile

You would then run the engine in node :islands@<hostname> specifying short name islands:

• cd islands_engine
• iex --sname islands -S mix # short name must be islands
• :observer.start # optional to observe the game(s) being played

Player1 starts the game from a different node using any short name:

• cd islands_text_client
• iex --sname client1 -S mix # short name is client1
• Islands.Text.Client.start("Eden", "Adam", :m) # gender is :m

Player2 joins the game from yet another node using any short name:

• cd islands_text_client
• iex --sname client2 -S mix # short name is client2
• Islands.Text.Client.join("Eden", "Eve", :f) # gender is :f

Multiple games can be played simultaneously in this fashion.

Notes

When starting a game, a player can specify "auto mode" with a pause duration (in milliseconds) between moves:

Example:

• cd islands_text_client
• iex --sname client1 -S mix
• Islands.Text.Client.start("Eden", "Adam", :m, mode: :auto, pause: 5000)

Likewise when joining a game, a player can specify "auto mode" with a pause duration (in milliseconds) between moves:

Example:

• cd islands_text_client
• iex --sname client2 -S mix
• Islands.Text.Client.join("Eden", "Eve", :f, mode: :auto, pause: 3000)

The default mode is :manual and the default pause is 0 milliseconds.

Any combination of modes is possible for the two players.
