我怎样才能让我的t-to-to游戏以平局结束？ [英] How do I make it possible for my ti-tac-toe game to end in a tie?

问题描述

我在ruby中写了一个井字游戏程序。一切都在发挥作用，除了游戏不能以平局结束。有什么建议吗？



这是我的代码：

I wrote a tic-tac-toe program in ruby. Everything is working except that the game can't end in a tie. Any suggestions?

Here is my code:

class Game

        def initialize
                @board=Array.new
                @board[1]="1  __|"
                @board[2]="__"
                @board[3]="|__"
                @board[4]="\n2  __|"
                @board[5]="__"
                @board[6]="|__"
                @board[7]="\n3    |"
                @board[8]="  "
                @board[9]="|  "
                @turn="o"
                @win_status = false
        end

        def turn
                @turn
        end

        def show_board
                puts "   1  2  3"
                @board.each do |i|
                        print i
                end
                puts ""
        end

        def set_turn #switches turns
        if @turn == "x"
                @turn = "o"
        else @turn == "o"
                @turn = "x"
        end
        end

        def make_move
                puts "Enter x coordinate"
                x=gets.to_i
                puts "Enter y coordinate"
                y=gets.to_i
if y==1 && x==1 && !@board[1].match(/[xy]/)
        @board[1]="1  _"+@turn+"|"
elsif y==2 && x==1 && !@board[2].match(/[xy]/)
        @board[2]="_"+@turn
elsif  y==3 && x==1 && !@board[3].match(/[xy]/)
        @board[3]="|_"+@turn
elsif y==1 && x==2 && !@board[4].match(/[xy]/)
        @board[4]="\n2  _"+@turn+"|"
elsif y==2 && x==2 && !@board[5].match(/[xy]/)
        @board[5]="_"+@turn
elsif y==3 && x==2 && !@board[6].match(/[xy]/)
        @board[6]="|_"+@turn
elsif y==1 && x==3 && !@board[7].match(/[xy]/)
        @board[7]="\n3   "+@turn+"|"
elsif y==2 && x==3 && !@board[8].match(/[xy]/)
        @board[8]=" "+@turn
elsif y==3 && x==3 && !@board[9].match(/[xy]/)
        @board[9]="| "+@turn+" \n"
else
        puts "You either entered an invalid coordinate or a a taken square. Please enter another coordinate"
        make_move
end

                        end

        def win_combo
                return [[@board[1][4] + @board[2][1] + @board[3][2]], [@board[4][5] + @board[5][1] + @board[6][2]], [@board[7][5] + @board[8][1] + @board[9][2]],[@board[1][4] + @board[4][5] + @board[7][5]], [@board[2][1] + @board[5][1] + @board[8][1]], [@board[3][2] + @board[6][2] + @board[9][2]], [@board[1][4] + @board[5][1] + @board[9][2]], [@board[3][2] + @board[5][1] + @board[7][5]]]
        end

        def check_win
                #if some row or column or diagonal is "xxx" or "ooo" then set @win_status = true
                self.win_combo.each do |arr|
                        str = arr.join
                        if str == "xxx"
                        puts "\nX Wins!"
                        return true
                        elsif str == "ooo"
                        puts "\nO Wins!"
                        return true
                        end
                end
                return false
        end
<pre lang="vb">g = Game.new
while g.check_win != true
        g.show_board
        g.set_turn
        g.make_move
end
end

推荐答案

我认为你需要在check_win函数之后再添加一个子句

I think you need to add one more clause to check_win function after

if str == "xxx"
    puts "\nX Wins!"
    return true
elsif str == "ooo"
    puts "\nO Wins!"
    return true
else
    #check for empty slots left
    #if empty slot count = 0 
    #    then game draw
    #    return true
    #end
end

我的主要语言不是ruby，因此无法编写代码：）。

My primary language is not ruby so can't write code for that :).
