JavaFX-Online-Chess

An (incomplete) chess program written in JavaFX. Note that by default this program uses localhost for multiplayer.

Feature List

• Fully functional chessboard GUI
• Movable chess piece objects with team-colored piece images
• Game board drawn differently for white/black
• Supports 2 player online games
  • Game board is frozen while waiting for opponent's move
• Offline mode for local play
• Unique piece movement for King, Queen, Rook, Bishop, Knight, and Pawn
  • Pawns restricted to one-way movement
• Chat area for messages between players
• Both client & server validate moves before updating board
• Licensed for reuse under MIT License
• Customizable board colors via stylesheet.css

Missing Features

• Special pawn rules (Piece promotion, en passant)
• Indicators for check, checkmate, and stalemate
• Handling for edge case where client & server disagree on whether a move is valid
• Allow castling

Bugs

• Queens, Rooks, and Bishops can move past occupied spaces
• GameBoard can be interacted with before client-server connection is established

Edge Cases

• If the client cannot find a server (ie: client started before server), chatbox displays "Error: Failed to connect to server"
