当我第二次输入 stick 时，它不像第一次那样打印分数，不知道为什么它会跳过这个

Question

任务

Write a program that lets a user player a solo game of Blackjack. The program should:

Ask the player if they want to "hit" or "stick".

If the player hits, add a card to their hand.

If the player sticks, end the game.

Keep asking the player if they want to "hit" or "stick" until they say "stick".

Each time the player hits, calculate the score for the player's hand and puts Score so far: and the score.

e.g. Score so far: 23

A score is calculated by adding up the values of each of the cards in the player's hand.

Value for each card:

"two": 2

"three": 3

"four": 4

"five": 5

"six": 6

"seven": 7

"eight": 8

"nine": 9

"ten": 10

"jack": 10

"queen": 10

"king": 10

"ace": 11 (This is slightly different from real Blackjack.)

When the game is over, puts the outcome of the game.

If the player's score is <= 21, puts You scored: and the final score

e.g. You scored: 20

If the player's score is > 21, puts You busted with: and the final score.

e.g. You busted with: 25

As part of your solution, there should be four specific methods:

random_card: This has already been written for you. You don't need to change it.

move: Asks the player for a move. If they enter hit or stick, it returns the move. If they enter something else, it keeps asking them until they enter hit or stick.

score: Takes an array of cards and returns the score for the hand as an integer.

run_game: uses the other methods to run a game of Blackjack.

Note: When you run the automated tests, make sure to remove from the top level of the file any calls to run_test or other methods.

Note: To stop the game when the user sticks, don't use exit to quit the program because this will break the automated tests. To exit a while loop early, use the break keyword.

You don't need to change this method!

def random_card
  cards = ["two", "three", "four", "five", "six", "seven",
           "eight", "nine", "ten",
           "jack", "queen", "king", "ace"]
  cards[rand(13)]
end
random_card

def move
  puts "hit or stick?"
  turn = gets.chomp
  if turn == "hit"
    "hit"
  elsif turn == "stick"
    "stick"
  else
    move
  end
end

def score(array)
  values = {
    "two" => 2,
     "three"=> 3,
      "four" => 4,
       "five"=> 5,
        "six"=> 6,
         "seven"=> 7,
           "eight" => 8,
            "nine" => 9,
             "ten" => 10,
           "jack" => 10,
            "queen" => 10,
             "king" => 10,
              "ace" => 11
            }
           total = 0
           array.each do |card|
             total += values[card]
  end
  total
end

def run_game
 hand = []
  while move == "hit"
   hand.push(random_card)
   if score(hand) <= 21
   puts "Score so far: #{score(hand)}"
 else
     puts "you busted with #{score(hand)}"
     break
   end
     if move == "stick"
       puts "You scored: #{score(hand)}"
       break
   end
 end
end
run_game

Answer 1

您的问题在这里：

if move == "stick"
   puts "You scored: #{score(hand)}"
   break

您又在调用移动函数了。

试试这个 run_game 函数，不同之处在于每个循环只调用一次移动。

def run_game
 hand = []
 currMove = move
 while currMove == "hit"
  hand.push(random_card)
  if score(hand) <= 21
   puts "Score so far: #{score(hand)}"
  else
   puts "you busted with #{score(hand)}"
   break
  end
  if currMove == "stick"
   puts "You scored: #{score(hand)}"
   break
  end
  currMove = move
 end
end

当我第二次输入 stick 时，它不像第一次那样打印分数，不知道为什么它会跳过这个

when i input stick the second time it doesnt print score so far like the first time, not sure why it skips this
