紅寶石猜字遊戲

Question

我是Ruby新手，正在和這個hang子手風格的猜字遊戲一起工作。我有兩個主要問題。這裏是我與現在的工作是什麼：

class Word_game 

    def initialize(word) 
    @word = word.downcase 
    @display_word = "_ " * word.length 
    end 

    def guess_the_word(word_guess) 
    word_guess.downcase 
    @word.split("").each_with_index do |word_letter, index| 
     if word_guess == word_letter 
      @display_word[index] = word_guess 
      p @display_word 
      puts "You're getting somewhere! Keep trying!" 
     end 
     end 
     if !@word.include? (word_guess) 
      puts "Nope, guess again..." 
     end 


    def win? 
    if @word == @display_word 
     puts "Congratulations you won!!! You are the word master!!!" 
     true 
    else 
     false 
    end 
    end 

    def lose? 
    if @attempts == 0 
     puts "You lose!!" 
     true 
    end 
    end 

puts "Welcome to the Word Guessing Game! Let's see if YOU have what it TAKES!!!" 
puts "This is a 2 player game. " 
puts "Player 1... please enter a word for Player 2 to guess!" 
puts ">>" 

game_word = gets.chomp 
game = Word_game.new(game_word) 

attempts = 0 
guessed_letters = [] 

    until @attempts == game_word.length 
    puts "Ok Player 2, Guess a letter! GO!!!" 
    letter_guess = gets.chomp 
     if guessed_letters.include? letter_guess 
      puts "You already guessed that letter! Enter a new one." 
      letter_guess = gets.chomp 
     end 
    guessed_letters << letter_guess 
    game.guess_the_word(letter_guess) 
    if game.win? 
     attempts += 1 
    else game.lose? 
    end 
    end 
end 

• 首先，單詞進度應該是這樣的，如果這個詞是個招呼：

  h _ e _ _ o 
  

• 取而代之的是，這些空間不在正確的地方，看起來像這樣（運行我的代碼的實際結果）：

。

Ok Player 2, Guess a letter! GO!!! 
h 
"h _ _ _ _ " 
You're getting somewhere! Keep trying! 
Ok Player 2, Guess a letter! GO!!! 
o 
"h _ o _ _ " 
You're getting somewhere! Keep trying! 
Ok Player 2, Guess a letter! GO!!! 
e 
"he_ o _ _ " 
You're getting somewhere! Keep trying! 
Ok Player 2, Guess a letter! GO!!! 
l 
"hel o _ _ " 
You're getting somewhere! Keep trying! 
"hello _ _ " 

當用戶猜測這個單詞時，它不會放我的「恭喜」聲明並結束遊戲。

我也堅持我的'失敗'方法。我不確定如何修復該方法，以便在用戶用盡了所有嘗試並打印「丟失」語句時遊戲結束。

感謝您的幫助！

Answer 1

對於你的第一個問題，你的@display_word開始如下：

[0] = '_' # For h 
[1] = ' ' 
[2] = '_' # For e 
[3] = ' ' 
... 

當你猜'e'，例如，你這樣做：

@display_word[index] = word_guess 

凡index在"hello"等於1，第二個字符，所以你可以看到它不寫入@display_word的'e'索引。

對於第二個問題，有許多方法可以解決它。舉例來說，我會做一些喜歡使用@attempts_remaining從值10起左右，然後利用現有代碼：

if !@word.include? (word_guess) 
    @attempts_remaining -= 1 # Count failure to guess 
    puts "Nope, guess again..." 
end 

然後：

def win? 
    # If you've guessed all the letters, there's no '_' left in the display word 
    if !@display_word.include? ('_') 
    puts "Congratulations you won!!! You are the word master!!!" 
    true 
    else 
    false 
    end 
end 

def lose? 
    if @attempts_remaining == 0 
    puts "You lose!!" 
    true 
    end 
end 

最後，捏捏until循環終止條件：

until game.win? or game.lose? 

到win?和lose?現有的呼叫可以被刪除。

我想你會讓輸出太複雜。我會追蹤數組中的單詞和猜測。而不是一個display_word變量，我會使它成爲一種方法，可能「to_s」

順便說一下，R​​uby約定是使用CamelCase類的名稱。

class WordGame 
    def initialize(word) 
    @word = word.downcase.chars 
    @guesses = ["_"] * @word.size 
    end 

    def to_s 
    @guesses.join " " 
    end 

這應該解決您的間距問題。這也將簡化猜測。

此外，檢查是否已使用該字母應該可能由WordGame類處理。
