GameContinue() 未运行。应该循环回到 main() 的开头

Question

我目前正在制作一个小猪游戏，大部分功能都可以正常运行。如果玩家 1 决定停止滚动，而玩家 2 决定停止滚动，我需要代码工作，游戏将循环返回，直到一个玩家达到 20 分。目前，代码在 1 运行 through.

之后结束

                        }

                {
                    turnOver = true;  
                    return; 
                }
                else 
                {
                    System.out.println("Incorrect entry, please try again");       // prompt retry
                    System.out.println("");
                    input = key.next();
                }
            }while(turnOver == false || dice != 1);
            
            
            playerTwoTotal += playerTwoScore;
            playerTwoScore = 0;
            if (playerTwoTotal >= FINAL_SCORE) {
                // System.out.println("YOU WIN!");
                gameOver = true;
                while (playerTwoTotal >= FINAL_SCORE)
                    ;

                break;
            }
        }
    }
    public static void GameContinue() {
        if (playerTotal < 20 && playerTwoTotal < 20) {                          //if neither players totals or 20 or greater
            PlayerOneTurn(); //go back to playerOne
        }
        else //if either one is 20 or greater
        {
            return; //go to main method and finish
        }
    }
    
}

我创建的 GameContinue() 函数是为了循环回到 PlayerOne。

public static void GameContinue() {
        if (playerTotal < 20 && playerTwoTotal < 20) { //if neither players totals or 20 or greater
            gameOver = false;
            PlayerOneTurn(); //go back to playerOne
        }
        else //if either one is 20 or greater
        {
            return; //go to main method and finish
        }
    }

我知道调用 PlayerOneTurn()；不会将其循环回 main 方法的开头。我试过像这样再次调用所有三种方法。

public static void GameContinue() {
        if (playerTotal < 20 && playerTwoTotal < 20) { //if neither players totals or 20 or greater
            gameOver = false;
            PlayerOneTurn(); //go back to playerOne
            PlayerTwoTurn();
            GameContinue();
        }
        else //if either one is 20 or greater
        {
            return; //go to main method and finish
        }
    }

显然这只是导致了一大堆错误。我应该如何让我的代码继续循环直到满足 GameContinue() 中的 if 语句？

Answer 1

正如 Ecto 评论的那样，您可以在主函数中使用 while 循环。此处显示：

public static void main(String[] args) {
    while (GameContinue()) {
        PlayerOneTurn();
        PlayerTwoTurn();
    }
    if (playerTotal >= FINAL_SCORE) {
        System.out.print("Current Score: Player 1 has " + playerTotal);
        System.out.print(", Player 2 has " + playerTwoTotal);
        System.out.println("");
        System.out.println("Player 1 wins!");
    }
    if (playerTwoTotal >= FINAL_SCORE) {
        System.out.print("Current Score: Player 1 has " + playerTotal);
        System.out.print(", Player 2 has " + playerTwoTotal);
        System.out.println("");
        System.out.println("Player 2 wins!");
    }
}

现在显然这是一个错误，因为 GameContinue() 是一个 void 方法。为了解决这个问题，您可以将 GameContinue() 更改为：

public static boolean GameContinue() {
    if (playerTotal < 20 && playerTwoTotal < 20) {
        gameOver = false;
        return true;
    } else {
        return false;
    }
}

这将解决您的问题，并且您的代码几乎没有改动。

GameContinue() 未运行。应该循环回到 main() 的开头
