Ruby-Tictaoe找到了赢家

我知道Tictatcoe的问题之前已经发布过，但是在看了其他帖子和大量在线研究之后，我仍然感到困惑。我真的很感谢你的帮助

总的来说，我不明白为什么合适的赢家没有出现，有时nil似乎被赋予了一个等于“X”或“O”的值。我也很难搞清楚猫的把戏，但我想我已经接近了

这是我的全部代码，如果有任何其他信息可以帮助找到解决方案，请告诉我：

class TicTacToe
def initialize
    row1 = [nil,nil,nil]
    row2 = [nil,nil,nil]
    row3 = [nil,nil,nil]
    @row1 = row1
    @row2 = row2
    @row3 = row3
end

def show_board
    print @row1
    puts
    print @row2
    puts
    print @row3
    puts
end

def prompt
    print " >>> "
end

def turn
    puts "Pick row #"
    print prompt
    row_choice = gets.chomp
    @row_choice = row_choice
    puts "Pick column #"
    print prompt
    column_choice = gets.chomp
    @column_choice = column_choice
end

def winner
    print "checking for winner..."
    if @row1[0] == @row1[1] && @row1[2]
        puts "We have a winner1!"
        replay()
    elsif @row2[0] == @row2[1] && @row2[2]
        puts "We have a winner2!"
        replay()
    elsif @row3[0] == @row3[1] && @row3[2]
        puts "We have a winner3!"
        replay()
    elsif @row1[0] == @row2[1] && @row3[2]
        puts "We have a winner4!"
        replay()

        puts "We have a winner7!"
        replay()
    elsif @row1[2] == @row2[2] && @row3[2]
        puts "We have a winner8!"
        replay()
    #elsif @row1 && @row2 && @row3 != nil
    #   puts "Catsgame - no one wins!"
    #   replay()
    else
        puts "nope"
    end

def replay
    puts "---------------------"
    puts "Would you like to play again? YES or NO"
    select = gets.chomp

        @row2 = [nil,nil,nil]
        @row3 = [nil,nil,nil]

谢谢大家!

你想要的是

if @row1[0] == @row1[1] && @row[0] == @row1[2]
    puts "We have a winner1!"
    replay()
elsif @row2[0] == @row2[1] && @row2[0] == @row2[2]
    puts "We have a winner2!"
    replay()

等等。

现在，您正在检查第一项和第二项是否相等，第三项是否存在。你要做的是对照第一项检查第二项和第三项，以确定它们是否都相等。

实际上，你最好检查谁是获胜者-

 if @row1[0] == @row1[1] && @ro1[0] == @row1[2] && @row1[0] == "X"
     puts "Player 1 Wins!"
     replay()
 elsif @row1[0] == @row1[1] && @row1[0] == @row1[2] && @row1[0] == "O"
     puts "Player 2 Wins!"
     replay()
 .....

您还需要将replay函数置于winner函数之上。

您的if语句没有按照您的想法执行。你需要a==b&&a==c，而不是a==b&&c谢谢你！我已经被困在这两天了，你这个摇滚！它正在工作：）
