Question

我正在打一场战争纸牌游戏。我只应该使用一个班级。当我运行它时，它正确分配card1和card2值，运行循环并打印正常，但它只分配RNG值一次，我需要它来打破循环并每次重新分配值，直到有人赢

我试过打破它，但这只会结束整个代码。我不是在寻找答案，只是一些输入和帮助。它应该起到作用，从失败者中扣除一分加入获胜者，除非它是一个平局。然后它运行War并扣除3并添加3（对于使用的卡数量）。一击零，游戏停止并赢得胜利者。

import java.util.Random;          

public class warGame {

    public static void main(String[] args) {

        String p1 = "Player 1";
        String p2 = "Player 2";
        int s = 10;
        int p1Score = s;
        int p2Score = s;
        Random card = new Random();
        int card1 = card.nextInt(14);
        int card2 = card.nextInt(14);
        int t = 1;
        int war1 = card.nextInt(14);
        int war2 = card.nextInt(14);
        System.out.println("Let's play War!");

        //Do while loop that runs the entirety of the program inside.
        do {
            System.out.println("Turn " + t++ + " -- Player 1's card: " + card1 + " Player 2's card: " + card2);

            //determines cards, calculates values and runs proper loop
            if (card1 > card2) {
                System.out.println("Player 1 wins!");
                p1Score += 1;
                p2Score -= 1;
                System.out.println("Scores -- " + "Player 1: " + p1Score + " Player 2: " + p2Score);
            } else if (card1 == card2) {
                System.out.println("Time for war!");
                System.out.println("Player 1's war card is: " + war1 + " Player 2's war card is: " + war2);
                if (war1 > war2) {
                    System.out.println("Player 1 wins the war!");
                    p1Score += 3;
                    p2Score -= 3;
                } else {
                    System.out.println("Player 2 wins the war!");
                    p1Score -= 3;
                    p2Score += 3;
                }
            } else {
                System.out.println("Player 2 wins!");
                p1Score -= 1;
                p2Score += 1;
                System.out.println("Scores -- " + "Player 1: " + p1Score + " Player 2: " + p2Score);
            }
        } while (p1Score > 0 && p2Score > 0);

        //The following will print out the winner and end the game. 

        if (p1Score == 0) {
            System.out.println("Player 2 wins the game!");
        } else {
            System.out.println("Player 1 wins the game!");
        }
    }
}

Answer 1

实际上简单的回答：您可以在do-while循环之外分配卡的值。这意味着除非你在循环中更改它们，否则这些值永远不会改变。

Answer 2

如果您希望循环具有不同的结果，则需要为其提供不同的值。

当你这样做时：

sudo yum install -y docker

您要为这四个变量分配随机值。但是，这些值永远不会改变。

我会用以下代码替换这些行：

int card1 = card.nextInt(14);
int card2 = card.nextInt(14);
int war1 = card.nextInt(14);
int war2 = card.nextInt(14);

然后：

int card1;
int card2;
int war1;
int war2;

这次变量＆＃39;每次迭代时，值都会有所不同。
