我如何询问用户是否希望在使用netbeans的每个骰子滚动后继续游戏 [英] How do I ask if the user would like to continue the game after each dice roll in java using netbeans

问题描述

大家好我需要这个问题的帮助：
骰子滚动游戏是用两个六面骰子玩的。玩游戏的用户将掷出两个骰子，并且将生成一到六个之间的两个随机数。这两个数字的总和将用于决定下一步。
如果总和是2,3或12，则玩家获胜。如果总和是7或11，那么他/她就输了。如果总和为4,5,6,8,9或10，那么程序会自动再次掷骰子直到玩家获胜或输掉。
每次掷骰子后，都会提示玩家输入。玩家应该决定游戏是否应该继续。
每次掷骰子后，也应显示赢或输的游戏数量。
我已经设法让第一部分工作，但无法确定如何提示用户，如果他们希望继续或他们赢了/输了多少游戏

Hi guys I need help with this question: A dice rolling game is played with two six-sided dice. A user playing the game, will roll the two dice and two random numbers between one and six will be generated. The sum of the two numbers will be used to decide the next step. If the sum is 2,3 or 12 then the player wins. If the sum is 7 or 11 then he/she loses. If the sum is 4, 5, 6, 8, 9 or 10 then the program automatically rolls the dice again until the player wins or loses. After every dice roll, the player will be prompted for an input. The player should decide if the game should continue or not. The amount of games won and lost should also be displayed after every dice roll. I have managed to get the first part to work but unable to work out how to prompt the user if they wish to continue or how many games they have won/lost

public class DiceGame {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

        while (true) {
            int dice1=(int)(Math.random()*6+1);
            int dice2=(int)(Math.random()*6+1);
            int sum = dice1 + dice2;

            System.out.println("Roll: total = " + sum);

            if (sum==2 || sum==3 || sum==12) {
                System.out.println("Sorry with a " +  sum  + " you loose :(");
                break;
            }
            else if(sum==7 || sum==11) {
                System.out.println("With a " + sum + " you win :)");
                break;
            }
        }
    }

}

推荐答案

扫描仪可用于提示用户询问他/她是否想要继续。

Scanner can be used to prompt user to ask whether he/she wants to continue or not.

你甚至可以跟踪号码时间骰子被滚动。

You can even track no. of times dices were rolled.

import java.util.Scanner;

public class DiceGame {

    public static int attempt = 1;
    /**
     * @param args
     *            the command line arguments
     */
    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
        int dice1 = (int) (Math.random() * 6 + 1);
        int dice2 = (int) (Math.random() * 6 + 1);
        int sum = dice1 + dice2;

        while (true) {
            System.out.println();
            System.out.println("Rolling dice for " + attempt + " time!");

            dice1 = (int) (Math.random() * 6 + 1);
            dice2 = (int) (Math.random() * 6 + 1);
            sum = dice1 + dice2;

            System.out.println("Roll: total = " + sum);

            if (sum == 2 || sum == 3 || sum == 12) {
                System.out.println("Sorry with a " + sum + " you loose :(!");
                System.out.println();
                break;
            } else if (sum == 7 || sum == 11) {
                System.out.println("With a " + sum + " you win :)!");
                System.out.println();
                break;
            }
            System.out.println();
            System.out.println("Do you wish to continue? Press 'y' for YES or ANY key for EXIT");
            if (!scanner.next().equalsIgnoreCase("y")) {
                break;
            }
            attempt++;
        }
        System.out.println("Thanks for playing dice game, you rolled the dice " + attempt + " times!");
    }
}

编辑：如果您希望在总和为4 5 6 8 9 10时自动滚动骰子，那么您将不再需要扫描仪，即用户输入是否继续。

If you want to roll the dices automatically when the sum is 4 5 6 8 9 10 then you would no more need Scanner i.e. user input whether to continue or not.

以下是相同的解决方案。

Here is the solution for the same.

public class DiceGame {

    public static int attempt = 1;

    public static void main(String[] args) {

        int dice1 = 0;
        int dice2 = 0;
        int sum = 0;

        while (true) {
            System.out.println();
            System.out.println("Rolling dice for " + attempt + " time!");

            dice1 = (int) (Math.random() * 6 + 1);
            dice2 = (int) (Math.random() * 6 + 1);
            sum = dice1 + dice2;

            System.out.println("Roll: total = " + sum);

            if (sum == 2 || sum == 3 || sum == 12) {
                System.out.println("Sorry with a " + sum + " you loose :(!");
                System.out.println();
                break;
            } else if (sum == 7 || sum == 11) {
                System.out.println("With a " + sum + " you win :)!");
                System.out.println();
                break;
                // this will roll the dices automatically
                // when sum is 4, 5, 6, 8, 9 or 10
            } else {
                System.out.println();
                System.out.println("With " + sum + " dices are rolled again automatically!!");
                attempt++;
            }
        }
        System.out.println("Thanks for playing dice game, you rolled the dice " + attempt + " times!");
    }
}

样品运行

Rolling dice for 1 time!
Roll: total = 4

With a 4, dices are rolled again automatically!!

Rolling dice for 2 time!
Roll: total = 6

With a 6, dices are rolled again automatically!!

Rolling dice for 3 time!
Roll: total = 2
Sorry with a 2 you loose :(!

Thanks for playing dice game, you rolled the dice 3 times!
