Added move legality. You can now mostly only make legal moves however I have not added something to checks if the king is in check. I made sure the move was legal by taking the startRow startColumn and endRow endColumn. I then look at what piece is being moved and ensure it is ok. If it isn’t nothing happens when you try to click and you have to make another move. I made sure that the correct colour moves as well. I also haven’t added pawn promotions, castling or en passant (tbh im not 100% certain on the rules of en passant). I couldn’t add castling as I don’t have a move history so would have no way of knowing if the king or rook have moved before. I’m now working on converting my current way of storing the board (a 2D array) into bitboards. After some research I found that bitboards are more than 5 times more efficient than arrays!
