陷入循環制作戰爭游戲

Question

我正在制作戰爭卡片游戲。 我只能上一堂課。 當我運行此程序時，它會正確分配card1和card2值，運行循環並可以正常打印，但它只分配一次RNG值，我需要它打破循環並每次都重新分配值，直到有人獲勝。

我嘗試破壞它，但這僅結束了整個代碼。 我不是在尋找答案，只是在尋找一些輸入和幫助。 除非是平局，否則它應該發揮作用，從失敗者的點數中減去贏家的點數。 然后它運行War並扣除3，然后加3（用於所使用的卡數）。 一擊至零，游戲停止並顯示獲勝者。

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

答案很簡單：您可以在do-while循環外分配卡的值。 這意味着除非您在循環中進行更改，否則這些值將永遠不會更改。

Answer 2

如果希望循環具有不同的結果，則需要為其提供不同的值。

當您這樣做時：

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

您正在為這四個變量分配隨機值。 但是，這些值永遠不會改變。

我將這些行替換為：

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

接着：

do {
    // update card values
    card1 = card.nextInt(14);
    card2 = card.nextInt(14);
    war1 = card.nextInt(14);
    war2 = card.nextInt(14);

    System.out.println("Turn " + t++ + " -- Player 1's card: " + card1 + " Player 2's card: " + card2);

這次，變量值在每次迭代中都會有所不同。
