MATLAB Battleship

Purpose:

A recreation of Battleship using the Milton Bradley rule set.

Code Overview:

The program is run through main.m which in turn runs a setup and calls menu(). From here, menu() will make calls to the other functions as necessary (such as makeBoard(), saveBoard(), playGame(), etc.).

main()

Entry point to the game, prepares variables, and calls menu().

menu()

Handles program navigation

menu( option 8 )

There is also bTests.m which can be called on the menu using option 8 (not shown on screen). This will run the validity test on the boards included in Test Boards in accordance to the rule set.

getInput() & Cord()

Used in tandem to get user input in traditional coordinates (A1, B4, C9, D10, etc.) and translate into matrix notation (boards are set up as matrices).

makeBoard( mode )

Function varies depending on the mode, but will always check for board validity (checked through local canPlace()).

User

Asks user to select and place ships along the board.

CPU

Randomly assigns locations to ships.

saveBoard()

Takes input board data type and saves it to the local Boards folder as the next "empty" numeral. For example, if there are 6 boards (numbered 0-5), then the current board will be saved as b6.txt.

displayBoardOnly()

Takes input board and searches the local Boards folder for the corresponding board. The board is then plotted and labeled according to the board number (from the file name).

playGame()

Game handler with different, albeit unused, modes. Calls board generation first (random if called from quickplay, otherwise user-selected for the user and random for the CPU). Variables for stat handling are also maintained. The game loop will then run. So long as there is no winner, a new turn will run. Each turn the players select a target (random for the CPU) and the turn's operations are executed with feedback for any hits and sunken ships. Game state is checked for victory at the end of each turn, and stats are displayed at the end of the game.

displayGame()

Traverses the current state of the board matrices and plots them for display. Each segment is displayed through points and markers, with a blank (or blue space) for open water, a white X for misses (sploosh), a red X for hit spaces, and a black square for ship segments (which become visible for enemy ships when the entire ship is taken down).
