Method Detail

getMove

public int[] getMove(int[] board,
                     boolean isWhite,
                     int movesRemaining)
              throws java.rmi.RemoteException

This method returns a move for the given board, board.

Specified by:

getMove in interface Player

Parameters:

board - --- The board is encoded as a 33 integer array. board[0] is unused. For i from 1 to 32, board[i] indicates what piece, if any is position i on the board, using the official checkers numbering scheme. board[i] = -2 for a black king, -1 for a black pawn, 1 for a white pawn, 2 for a white king, and is 0 if the position is unoccupied

isWhite - is true if the player should make a move for White.

movesRemaining - is the number of moves remaining before a draw is called

Returns:

First element of the array is the position of the piece to be moved. The remaining elements are subsequent positions to which that piece moves. (There will usually be only one remaining element, unless result encodes a multiple capture/jumping move.) Thus a move from position 17 to 10, jumping over an opposition piece at position 14 would be encoded via the array: {17, 10}. It is important that the length of the array be exactly 1+ the number of moves made by the piece.

Throws:

java.rmi.RemoteException

main

public static void main(java.lang.String[] args)

Debugging: creates two players named Black and White and registers them with RMI.

Parameters:

args - Two command-line arguments: the first should be either '1' or '2', indicating whether the created Player should be rmi-registered as 'first' or 'second'. The second argument should be the name of the Player.

Example usage:
java -Djava.security.policy=permit.txt referee.HumanPlayer 1 "Fraser"

getName

public java.lang.String getName()
                         throws java.rmi.RemoteException

Here's your chance to be imaginative.

Specified by:

Returns:

the name of the agent (hopefully something memorable!)

Throws:

java.rmi.RemoteException
