我正在寫一個'洗牌程序'來和Ruby一起玩。認爲這是個人的功課,我自己分配了解更多:)ruby - 如何重新排列基於另一個數組的數組?
,我想輸出是在這裏:
----Triple Cut Deck on 3rd and 5th cards---------
-- reset
Number: 1, Position: 3, Suit: Clubs, Card: 3
Number: 2, Position: 4, Suit: Clubs, Card: 4
Number: 3, Position: 1, Suit: Clubs, Card: 5
Number: 4, Position: 2, Suit: Clubs, Card: 6
Number: 5, Position: 5, Suit: Clubs, Card: Ace
Number: 6, Position: 6, Suit: Clubs, Card: 2
,但我得到:
----Triple Cut Deck on 3rd and 5th cards---------
-- reset
Number: 1, Position: 3, Suit: Clubs, Card: 3
Number: 2, Position: 4, Suit: Clubs, Card: 4
Number: 3, Position: 5, Suit: Clubs, Card: 5
Number: 4, Position: 5, Suit: Clubs, Card: 5
Number: 5, Position: 6, Suit: Clubs, Card: 6
Number: 6, Position: 6, Suit: Clubs, Card: 6
基本上,我想得到的是重新命名的牌,以便'Ace,2,3,4,5,6「將他們的卡順序從」1,2,3,4,5「改變爲」5,6,3,4,1 ,2「,換句話說,底部的兩張牌(順序排列),底部的兩張牌在頂部和中間保持不變,這是一個3路切割的版本
我很難讓這個數組'重新排序'正常工作。 眼下卡「秩」和card_position越來越弄亂了如上所示,用重複,等等
class Card
RANKS = %w(Ace 2 3 4 5 6 7 8 9 10 J Q K)
SUITS = ['Clubs', 'Diamonds', 'Hearts', 'Spades']
SCORES = [1..54]
attr_accessor :rank, :suit, :card_position
def initialize(id, rank='', suit='', card_position=0)
self.card_position = id
self.rank = RANKS[(id % 14)-1]
self.suit = SUITS[(id/14)]
end
end
class Deck
DECK_SIZE = 6
attr_accessor :cards
def initialize
self.cards = (1..DECK_SIZE).to_a.collect { |id| Card.new(id) }
@deck = cards
end
def process_cards
puts "\n----Triple Cut Deck on 3rd and 5th cards---------"
self.triple_cut_deck(3, 5, true)
self.show_deck
end
def show_deck
@deck.sort_by!(&:card_position).each_with_index do |card, index|
puts 'Number: ' + (index+1).to_s + ", Position: #{card.card_position.to_s}, Suit: #{card.suit.to_s}, Card: #{card.rank.to_s}"
end
end
def triple_cut_deck(top_cut, bottom_cut, reset_deck=false)
reset_the_deck(reset_deck)
top_cut-= 1
bottom_cut-= 1
deck_array_size = DECK_SIZE-1
@new_deck = []
@new_deck[0..1] = @deck[4..5]
@new_deck[2..3] = @deck[2..3]
@new_deck[4..5] = @deck[0..1]
DECK_SIZE.times do |card|
@deck[card].card_position= @new_deck[card].card_position
@deck[card].card_position= @new_deck[card].card_position
@deck[card].card_position= @new_deck[card].card_position
end
end
def reset_the_deck(reset_deck)
puts reset_deck == true ? " -- reset" : 'no-reset'
initialize if (true && reset_deck)
end
end
你有沒有考慮過使用[費雪耶茨洗牌(http://en.wikipedia.org/wiki/Knuth_shuffle)洗牌? – ddfreyne 2012-02-07 19:48:14
是的,但更喜歡不使用它來更好地學習過程,但謝謝! – 2012-02-07 19:55:26
