Question

我正在尝试使用Java制作一个Hangman游戏，但我在互联网上发现的大多数都是有一个while循环，但由于这是一个聊天机器人的一部分，我需要它与if语句，但它不是工作。它正确地抓住第一个单词，发送6个破折号，但每次猜测都是“错误的”，生命就会消失。有谁知道我做错了什么？提前谢谢！

private static String hangmanStarted = "0";
private static String hangmanInitialized = "0";
private static String hangmanSecret = "";
private static int hangmanLives = 10;

private void cmdHangman() {
    if (hangmanStarted.equals("0")) {
        try {
            secretWord();
        } catch (FileNotFoundException e1) {
            e1.printStackTrace();
        }
        hangmanStarted = "1";
        sendMessage("Hangman has started!\nType: ''.guess letter''\nto guess a letter!");
    }
}

private void cmdGuess() {
    if (hangmanStarted.equals("1")) {
        String input = lastMsg.replace("[^a-zA-Z]", "");
        input = input.replace("guess", "");
        input = input.toLowerCase();
        try {
            Hangman(input);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

public static void Hangman(String input) throws IOException {
        StringBuilder guessedLetters = new StringBuilder();
        String dashes = secretDashes();
        if (guessedLetters.toString().contains(input)) {
            sendMessage("This word is already guessed");
        } else {
            if (hangmanSecret.contains(input)) {
                guessedLetters.append(input);
                if (hangmanSecret.equals(letterConversion(hangmanSecret, secretDashes(), input))) {
                    sendMessage("You win!");
                    hangmanInitialized = "0";
                    hangmanStarted = "0";
                    guessedLetters.delete(0, guessedLetters.length());
                } else {
                    guessedLetters.append(input);
                    sendMessage("Letter was found!\nWord: " + letterConversion(hangmanSecret, secretDashes(), input));
                }
            } else {
                guessedLetters.append(input);
                hangmanLives = hangmanLives - 1;
                sendMessage("Word: " + dashes + "\nLives: " + hangmanLives);
                if (hangmanLives == 0) {
                    sendMessage("GAME OVER: You are dead.");
                    hangmanInitialized = "0";
                    hangmanStarted = "0";
                    hangmanLives = 10;
                    guessedLetters.delete(0, guessedLetters.length());
                }
            }
        }
    }

    public static void secretWord() throws FileNotFoundException {
        if (hangmanInitialized.equals("0")) {
            hangmanInitialized = "1";
            Scanner infile = new Scanner(new FileReader("hangWords.txt"));
            hangmanSecret = infile.next();
            infile.close();
        }
    }

    public static String secretDashes() throws FileNotFoundException {
        StringBuilder dashes = new StringBuilder();
        for (int count = 0; count < hangmanSecret.length(); count++) {
            dashes.append('-');
        }
        return dashes.toString();
    }

    public static String letterConversion(String secret, String dashes, String letter) {
        StringBuilder conversion = new StringBuilder();
        for (int index = 0; index < secret.length(); index++) {
            char secretChar = secret.charAt(index);
            secret = String.valueOf(secretChar);
            char letterChar = letter.charAt(index);
            if (secret.equals(letter))
                conversion.setCharAt(index, letterChar);
            dashes = conversion.toString();
        }
        return dashes;
    }

应该做什么：

我用命令启动Hangman。我猜通过guess命令发出的信件。 guess命令的输入被转发给Hangman void。刽子手检查这封信是否已经猜到了。如果没有，请检查该字母是否在保密字中，并向用户显示猜测的字母。如果它不在秘密词中，则删除生命。如果生命是0，结束游戏。

PS。是的，我知道，我使用的是字符串而不是布尔值，但这是同样的事情，我暂时做了以测试这是不是问题，呵呵。

编辑：这不是同一个问题。在更改了这行代码之后，问题仍然存在。

代码中的这一行不正确：

 if (secret == letter)

它应该是：

if(secret.equals(letter))

因为您正在使用String。
