$ ruby lib/battleship_runner.rb

And you're ready to play!

Setup

The game will ask you to create your own ships or use two by default (a 2 units-long Destroyer and a 3 units-long Submarine) and to enter the height & width of the board.

Placing your ships

Enter coordinates to place your ships on the board. For the coordinates to be valid they have to be:

• Equal to the length of the ship
• Vertical or horizontal
• Consecutive coordinates
• Exist within the board
• Do not overlap with other ships.

Placing your shots

After placing all your ships you will be asked to enter coordinates for your shot. For the coordinates to be valid they have to:

• Exist within the board
• Be new coordinates. You can't shoot in the same place twice.

Reading the board

• 'S' means there is a ship there. It will be visible in the 'Player Board'
• 'M' means the shot was a Miss.
• 'H' means the shot was a Hit.
• 'X' means the ship has been sunk.
• '.' it is a cell that has not been shot and does not contain a ship.

Winning

You have to sink all of your opponents ships before they do! Be careful! If the computer hits a ship, it will start shooting surrounding cells to try to beat you!
