java - 解决随机数游戏逻辑时遇到问题

Question

我对java编程比较陌生。我目前正在开发一个迷你猜谜游戏，作为学习更多 Java 的项目。我遇到以下问题:

以下是我无法解决的 4 个主要问题。

• 记录每个用户的答案(如果不正确)。
• 如果用户是正确的，则在后续回合中跳过它们。
• 当所有玩家都猜对了自己的数字后，打印出每个玩家猜对的次数、错误的答案，并显示玩家的排名。
• 询问用户是否希望再次玩。如果是这样，请重置所有值。

这是我编写的方法；

import java.io.*;

public class MultiPlayerRandomGame {

// this method asks how many users will be playing and returns the number of users
public static int howManyUsers() {

    System.out.println("How many users will be playing?");
    int players = IO.readInt();
    return players;
}

// this method generates and returns a random number 
public static int generateRandomNumber() {

    int randomNumber = (int) (Math.random() * 100);
    return randomNumber;
}

// this method compares user's entered guess and the generated random number then returns true/false
public static boolean compareGuess(int guess, int randomNumbers) {

    boolean isGuessCorrect = false;

    if (guess == randomNumbers) {
        System.out.println("CORRECT!");
        isGuessCorrect = true;

    } else if (guess > randomNumbers) {
        System.out.println("Too High");

    } else if (guess < randomNumbers) {
        System.out.println("Too Low");
    }

    System.out.println("test1");
    return isGuessCorrect;
} 

// this method determines whether Player N is correct or incorrect
public static boolean nextPlayer(int numOfUsers, int[] numberOfGuesses, int[] randomNumbers, int[][] numberBoard) {

    for (int n = 0; n < numOfUsers; n++) {
        int guessedNumber = numberOfGuesses[n];

        /*      if (guessedNumber == 0) {
            return false;   
        }*/

        if (numberBoard[n][guessedNumber] != randomNumbers[n]) {
            return false;
        }
    }
    return true;
}

/* this method is supposed to print out the number of guesses it took each player to guess their correct number
 * CORRECTION: change the logic of this method to printing the number of guesses for one player then
 * in the main method or wherever, make a for loop that prints out the number of guesses for each player
 */
public static void amountOfGuesses(int numOfUsers, int [] numberOfGuesses, int [][] numberBoard) {

    int n = 0;
    for ( int i = 0; i < numOfUsers; i++ ) {
        n = n + 1;
        System.out.println("Player " + n + " guessed " + numberOfGuesses[i]+ " time(s)");
    }
}

// this method determines whether the user(s) would like to play again
public static boolean playAgain(String answer) {

    boolean userWillPlayAgain;

    if (answer.compareToIgnoreCase("no") == 0) {
        userWillPlayAgain = false;
    }
    else {
        userWillPlayAgain = true;
    }
    return userWillPlayAgain;
}

// this method controls the entire game
public static boolean playGame(){

    boolean gameTerminate = false;
    int numOfUsers = howManyUsers();
    int [] randomNumbers = new int[numOfUsers];
    int [] numberOfGuesses = new int [numOfUsers];  
    int [][] numberBoard = new int [numOfUsers][100];

    // this for loop assigns the n random number(s) to the n player(s)
    for (int n = 0; n < numOfUsers; n++){
        randomNumbers[n] = generateRandomNumber(); 
        System.out.println("PLAYER " + (n+1) + "'s RANDOM NUMBER: " + randomNumbers[n]);
    }

    do { 
        for (int i = 0; i < numOfUsers; i++) {
            int guessedNumber = numberOfGuesses[i];

            if (guessedNumber == 0 || numberBoard[i][guessedNumber-1] != randomNumbers[i]) {
                System.out.println("Enter your guess Player " + (i+1) + ":");
                int enteredGuess = IO.readInt();


                numberBoard[i][guessedNumber] = enteredGuess;
                numberOfGuesses[i] = guessedNumber + 1;

                if(compareGuess(enteredGuess, randomNumbers[i])){
                    return true;

                }
            }
        } 

        /* int n = 0;
         * for ( int j = 0; j < numOfUsers; j++ ) {
            n = n + 1;
            System.out.println("Player " + n + " guessed " + numberOfGuesses[j]+ " time(s)"); }
         */


    } while (nextPlayer(numOfUsers, numberOfGuesses, randomNumbers, numberBoard) == false);


    // System.out.println("test"); 
    return gameTerminate;
}

public static void main(String[] args){
    boolean playing = true;
    while (playing) {
        playGame();

        System.out.println("Would you like to play again?");
        String answer = IO.readString();

        playing = playAgain(answer);
    }
    System.out.println("OK, goodbye!");
  }
}

目前的主要问题:游戏终止并询问用户是否愿意在玩家猜出他们的数字后再次玩，而不是在每个玩家都猜出他们的数字后。

我是否需要实际的对象来实现这一点并跟踪每个玩家，或者在没有对象的情况下仍然可以解决这个问题吗？这是一个我不熟悉的领域。

Answer 1

现在，只要任何猜测从 compareGuess 返回正确，您的 playGame 方法就会返回 true 返回到 main。

我建议在 playGame 中设置另一个数组 boolean[] CorrectGuess ，如果玩家猜测正确，则将玩家编号索引标记为 true 。您还可以使用这个新数组来跳过猜对的玩家。一旦所有玩家都被标记为 true，您就可以返回main。
