无法弄清楚为什么无法正确解决

Question

所以，我正在为一个班级做这项作业。 这是一门Java类，我应该做一个游戏，掷出两个骰子，将它们相加，然后将它们加到您的回合得分中。 然后询问是否要继续播放。 当转弯得分达到20或决定通过时，它将进入计算机。 它应该每回合打印分数，然后当有人达到100分时，宣布获胜者。 但是，无论如何，无论我跑了多少次，每回合结束时的得分都是0。 当一个玩家掷出1时，他们的回合分数将被取消，并转移到另一位玩家上；如果他们掷出双1，则到目前为止，他们将失去所有积分。 这是我的代码，您能找出为什么分数变量不更新吗？ 谢谢。

主要问题是，您分配当前分数的else条件处于错误的区域。 （这些）：

else {
    player1turn = a+b ;
} 

试试这个代码：

public static void main(String[] args) {
    // TODO Auto-generated method stub  
    Scanner scan = new Scanner(System.in);
    int player1 = 0;
    int player2 = 0;
    int a, b, c, player1turn, player2turn, input;        
    int pig = 1;
    Random r = new Random();
    do{

        do {

            player1turn=0;
            a = r.nextInt(6)+1;
            b = r.nextInt(6)+1;
                if( a==1 || b==1){
                    if (a == 1 && b == 1){
                        player1 = 0;
                        break;
                    }
                    else if (a==1 || b==1){
                        player1turn=0;
                        break;
                    }
                }else {
                    player1turn = a+b ;
                }
            player1 += player1turn;
            System.out.println("Player1 score is " + player1 + " and player2 score is " + player2);
            System.out.print("Do you want to keep playing? Enter 1 to continue. Enter any other number to pass.");
            input = scan.nextInt();
                if (input != 1){
                    break;
                }
        } while (player1turn <= 20);

        do{
            player2turn=0;
            a = r.nextInt(6)+1;
            b = r.nextInt(6)+1;

            if( a==1 || b==1){
                if (a == 1 && b == 1){
                    player2=0;
                    break;
                } else if (a==1 || b==1){
                    player2turn=0;
                    break;
                }               
            }else {
                player2turn = a+b ;
                player2 += player2turn;
            }

        }while (player2turn<=20);

    } while (player1 < 100 || player2 < 100);
    if (player1>player2)
        System.out.print("Player 1 wins");
    else
        System.out.print("Player 2 wins");

}

我已经修改了if循环。 您可以尝试以下方法：

import java.util.Scanner;
import java.util.Random;
public class PlayPig {

public static void main(String[] args) {
    // TODO Auto-generated method stub  
    Scanner scan = new Scanner(System.in);
    int player1 = 0;
    int player2 = 0;
    int a, b, c, player1turn, player2turn, input;
    int pig = 1;
    Random r = new Random();
    do{
        do {
            player1turn=0;
            a = r.nextInt(6)+1;
            b = r.nextInt(6)+1;
                if (a == 1 && b == 1){
                        player1=0;
                        break;
                }
                else if((a== 1 && b!= 1) || (a!=1 && b== 1){
                    player1turn=0;
                    break;
                }
                else{
                    player1turn= a+b ;
                }
                player1= player1+player1turn;
            System.out.println("Player1 score is " + player1 + " and player2          score is " + player2);
            System.out.print("Do you want to keep playing? Enter 1 to      continue. Enter any other number to pass.");
            input = scan.nextInt();
                if (input != 1)
                    break;
        }
        while       
            (player1turn <= 20);
        do{
            player2turn=0;
            a = r.nextInt(6)+1;
            b = r.nextInt(6)+1;
            if (a == 1 && b == 1){
                        player2=0;
                        break;
                }
                else if((a== 1 && b!= 1) || (a!=1 && b== 1){
                    player2turn=0;
                    break;
                }
                else{
                    player2turn= a+b ;
                }
                player2= player2+player2turn;
        }
        while
            (player2turn<=20);
    }
    while 
        (player1 < 100 || player2 < 100);
    if (player1>player2)
        System.out.print("Player 1 wins");
    else
        System.out.print("Player 2 wins");
