Rules Module
3
Rules Methods

• protected boolean bitboard 8x8 bit
  representation of the possible legal moves for
  this piece. This is updated on every turn.
• public abstarct void applyMotion(int
  chessBoard) This method applies the piece's
  motion on it's bitboard. This is called at the
  beginning of every turn.

4
Rules Methods

• public GameObject(int row, into column, boolean
  white) Constructor that takes the row and
  column positions, and a variable that represents
  whether this piece is white or black.
•  
• public void setPosition(int row, int column)
  Sets this piece's position.

5
Rules Methods

• public GameObject(int row, into column, boolean
  white) Constructor that takes the row and
  column positions, and a variable that represents
  whether this piece is white or black.
• public void setPosition(int row, int column)
  Sets this piece's position.

6
Rules Methods

• public ChessBoard() - Constructor that
  initializes chess board with pieces in starting
  locations. All variables are initialized, each
  GameObjects bitboard is created.
• public int getBoard() - Returns the integer
  representation for the current state of the chess
  board.

7
Rules Methods

• private boolean isLegal(int piece, int row, int
  column) Checks to see whether moving a piece to
  the specified position is legal.
• private boolean isInCheck(int chessBoard,
  boolean white) Checks if the specified colors
  king is in check.

8
Rules Methods

• public boolean move(int piece, int row, int
  column) This method is what the GUI will use to
  communicate with the rules module. This method
  will check whether the given move is legal, and
  return true if the move was successful.

Networking Module
10
Networking Variables

• private Socket connection Object that handles
  application level communication over TCP
  connection.
• private BufferedReader in Attached to the
  connections input stream and catches all incoming
  communications.
•  
• private PrintStream out Attached to the
  connections output stream and sends messages
  through the socket.

11
Networking Methods

• public void connect(String host, int port)
  Launches a thread to establish a connection to
  the host specified on the port given.
• public void host(int port) Launches a thread to
  listen on the supplied port for an incoming
  connection.

12
Networking Methods

• public void listen(Socket s) Launches a thread
  on the socket supplied to listen for incoming
  communications, messages, moves, etc...
• public void sendMove(int oldX, int oldY, int
  newX, int newY) Launches a thread to send the
  coordinates of a move, where it moved from and
  where it moved to.

13
Networking Methods

• public void sendMsg(String msg) Launches a
  thread to send a String to the opponent.

14
Networking Inner-classes

• public class ConnectThread extends Thread
  Thread that handles connection to a host.
• public class hostThread extends Thread a thread
  that handles listening on a sockect for an
  incoming connection.
• public class listenThread extends Thread - Thread
  that handles listening to a socket for incoming
  messages.

15
Networking Inner-classes

• public class sendMsgThread extends Thread
  Thread that handles sending messages.
• public class sendMoveThread extends Thread
  Thread that handles sending of a move to the
  opponent.

GUI Module
17
GUI Methods

• public refresh(String message) - Allows the
  networking module to update the Gui as to when a
  new message is generated.

18
GUI Methods

• public refresh(int oldX, int oldY, int newX, int
  newY) - Allows the networking module to update
  the Gui as to when a new move is generated.
