♜ Chess GUI Clone made in C++ SFML graphics library ♜

♖ Chess GUI

• Chess GUI (Graphical User Interface) game made in SFML C++ Library

📖 Description

• Play chess!
• Graphical user interface
• Show possible moves when clicked on a specific piece
• Play against AI (feature coming)

Usage

• Left click to choose your piece
• • Now you can see all the possible moves!

Getting Started

⬇️ Installation

If you have CMake installed:

Open your Command Prompt or Terminal

For a single-configuration generator (typically the case on Linux and macOS):

• cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
  cmake --build build

For a multi-configuration generator (typically the case on Windows):

•  cmake -S . -B build
   cmake --build build --config Release

Compiling it yourself with SFML:

1. Clone this repository

git clone https://github.com/SteponasK/Chess-SFML.git

1. Configure your project, using online guide or a youtube video.

2. Compile all the files using Visual Studio or the IDE of your choice.

chess-sfml's Issues

Make a main menu screen, end menu screen.

Main menu:

• Choose style of the board/pieces.
• Change volume of the music.
• Add resolution changer.

End menu:

• Showing how many moves it took.
• You won/lost/drew by stalemate/checkmate/etc.
• Do you want to play again

Castling works when it shouldn't

Able to castle, when enemy piece has a vision of the squares, the king would be moving thru.

Chess logic plan

Need to implement logic for king being in check, dangerous moves, which would put king in check, and legal moves to defend him.
Current plan:

Idea 1:

• Continously loop over every piece's legal moves and store them in each piece's legal_moves vector .
• If any of the pieces legal_move vector has Kings coordinates (x, y) in it, then the King is check.
• If king is in check, he has to move to some other square, or be defended by some other piece, i would loop over all the pieces legal moves and remove these squares from Kings legal_moves.
• If i want to move other piece, and king is in check, i would simulate its every legal move(and that every move would check if the king is in check - if it is, then that move is not legal).

Improvements:

Store position of both the kings.
If king moves, update it's position.
Create isKingInCheck() function
iterate through all the opponents pieces:
for each piece, check if it can attack the king(compare piece legal moves, with king pos)

Create detectDangerousMoves(color) function:

Pseudocode:

      vector dangerous_moves
      
for ( piece in all_pieces):
	get piece legal moves:
		for (move in legalMoves):
			 new tempBoard = current_Board
                           tempBoard play move: move
			if isKingInCheck(color, tempBoard):
				dangerous_moves.pushback(move)
         return dangerous_moves.
