java - 蛇与梯子 - 在计算机转弯和掷骰子上添加延迟

Question

我正在创建游戏“蛇与梯子”。我使用的游戏模式可以让你与电脑对战。

当人类玩家掷骰子时，将调用 rollTheDiceAndMove 方法。我们等待 1 秒(骰子正在滚动......)。然后我们调用 move 函数，该函数实际上将棋子移动到指定的图 block 上。如果蛇或梯子被击中，我想再等 1 秒再去最后一 block 瓷砖。例如。我等待 1 秒，掷出 5 个，然后将 my_current_pos + dice_roll 放在前面，然后移动该棋子。如果蛇或梯子击中:再次延迟并再次递归移动。

最后，如果选择“对抗计算机”模式，当人类玩家移动时，我想再等一秒钟，计算机才会自动掷骰子。如下所示，我正在使用 Timer 和 TimerTask 类，但它非常复杂，因为 Timer 范围内的任何内容都会在一段时间后执行，但是计时器之外的代码会立即执行，这导致了许多错误和异步。

您建议使用什么来创建这种延迟？

public void rollTheDiceAndMove() {
    int diceRoll = gameBoard.rollDice();
    // delay for dice roll.

    new Timer().schedule(
        new TimerTask() {
            @Override
            public void run() {
                Platform.runLater(new Runnable() {
                    @Override
                    public void run() {
                        ////////////////////////////////////////////////////////////////////////////

                        gameGUI.indicateDiceRoll(diceRoll);
                        int newIndex = getPlayerIndexAfterRoll(diceRoll);
                        move(newIndex);
                        System.out.println("change turns");
                        swapTurns();
                        System.out.println(isComputerTurn());
                        gameGUI.updateCurrentTurnLabel();


                        if (newIndex == GameBoard.WIN_POINT) {
                            boolean restartGame = gameBoard.playAgainOrExit();

                            if (restartGame) {
                                Player winner = gameBoard.getCurrentPlayer();
                                gameGUI.updateScore(winner);
                                gameGUI.playAgain();
                            } else {
                                System.exit(0);
                            }
                        }

                        ////////////////////////////////////////////////////////////////////////////
                    }
                });
            }
        }, GameBoard.DICE_ROLL_DELAY
    );

    // try to recursively call this method again for computer turn.
}


public void move(int currentIndex) {
    int[] newCoordinates = gameBoard.getBoardCoordinates(GameBoard.NUMBER_OF_TILES - currentIndex);

    gameBoard.getCurrentPlayer().getPlayerPiece().setPosition(currentIndex);
    gameGUI.movePieceImages(newCoordinates[0], newCoordinates[1]);

    if (gameBoard.getTile(currentIndex).containsLadderOrSnake()) {
        // delay for moving to second tile.

        new Timer().schedule(
            new TimerTask() {
                @Override
                public void run() {
                    Platform.runLater(new Runnable() {
                        @Override
                        public void run() {

                            int updatedIndex = gameBoard.getUpdatedPosition(currentIndex);
                            move(updatedIndex);


                        }
                    });
                }
            }, GameBoard.SECOND_MOVE_DELAY *2
        );

        return;             // we need to return 'cause of recursion. Swap turns will be executed twice, one time for the initial call and the other time on above line.
    }
}

创建项目的副本并尝试使用 PauseTransition。

public void rollTheDiceAndMove() 
{
    int diceRoll = gameBoard.rollDice();
    System.out.println("Player: rolling the dice");

    PauseTransition pause = new PauseTransition(Duration.seconds(1));
    pause.setOnFinished(event ->{
        System.out.println("1 second after rolling the dice");
        gameGUI.indicateDiceRoll(diceRoll);
        int newIndex = getPlayerIndexAfterRoll(diceRoll);
        playerMove(newIndex);
        if(checkWin(Player))
        {
            System.out.println("Player won!");                
        }
        else
        {
            System.out.println("change turns");
            swapTurns();
            System.out.println(isComputerTurn());
            gameGUI.updateCurrentTurnLabel();
            computerRollDiceAndMove();
        }






    });
    pause.play();
}

public void computerRollDiceAndMove()
{
    int diceRoll = gameBoard.rollDice();
    System.out.println("Computer: rolling the dice");

    PauseTransition pause = new PauseTransition(Duration.seconds(1));
    pause.setOnFinished(event ->{
        System.out.println("1 second after rolling the dice");
        gameGUI.indicateDiceRoll(diceRoll);
        int newIndex = getComputerIndexAfterRoll(diceRoll);
        computerMove(newIndex);
        if(checkWin(computer))
        {
            System.out.println("Computer won!");
        }
        else{
            System.out.println(isComputerTurn());
            gameGUI.updateCurrentTurnLabel();
        }
    });
    pause.play();   
}
