Question

package uk.ac.sheffield.aca14js;

public class Chess {
    public static void main(String[] arg) {

        Board chessBoard = new Board();
        Pieces white = new Pieces(chessBoard,1);
        Pieces black = new Pieces(chessBoard,0);
        Display board = new TextDisplay();
        Player one,two = null;
        one = new HumanPlayer("John",white,chessBoard,two);
        two = new HumanPlayer("opponent",black,chessBoard,one);
        one.setOpponent(two);

        int x = 0;


        while (x == 0){
            board.showPiecesOnBoard(chessBoard.getData());
            while (one.makeMove() != true){
                System.out.println("Choose a valid move");
                board.showPiecesOnBoard(chessBoard.getData());          
                one.makeMove();         
            }   
            board.showPiecesOnBoard(chessBoard.getData());  
            while (two.makeMove() != true){
                System.out.println("Choose a valid move");
                board.showPiecesOnBoard(chessBoard.getData());          
                two.makeMove();         
            }       
        }
    }
}

我想要的是让玩家选择一个移动，如果有效则移动，如果不重新移动。

如果选择的每一个动作都有效，那么随着玩家轮流转动，游戏就会顺利进行。

如果一名玩家进行了无效的移动，那么即使他们进行了有效的移动，游戏也会继续转向，直到他们再次进行无效移动。

我的while循环有问题吗？（无限循环仅用于测试）。

您拨打makeMove()的电话太多了：

        while (one.makeMove() != true){
            System.out.println("Choose a valid move");
            board.showPiecesOnBoard(chessBoard.getData());          
            one.makeMove(); // remove this     
        }   
        board.showPiecesOnBoard(chessBoard.getData());  
        while (two.makeMove() != true){
            System.out.println("Choose a valid move");
            board.showPiecesOnBoard(chessBoard.getData());          
            two.makeMove(); // remove this
        }

由于您已经在循环播放条件中呼叫makeMove()，因此无需再次在循环播放器中调用它。

while循环不按预期行事？
