在Ruby中行内生成随机数

Question

我有两个简单动画的计数器，它们将数字放在彼此下面。如何使它们都在同一行上具有相同的功能？感谢您的观看！

1000.times do

    puts "Press Enter"
    gets

        x = rand (0..5)
        y = rand (0..5)

        # "x" counter
        10.times do |xx|

            meter = rand (0..5)
            if xx < 9
                print meter
                print "\r"
                sleep 0.08
                else print x
            end
        end

    puts

        # "y" counter
        10.times do |yy|

            meter = rand (0..5)
            if yy < 9
                print meter
                print "\r"
                sleep 0.08
                else print y
            end
        end

    puts

end

使用"\b"回退（0x08）字符而不是回车（0x0d）字符。

1000.times do

  puts "Press Enter"
  gets

  x = rand (0..5)
  y = rand (0..5)

  # "x" counter
  10.times do |xx|

    meter = rand (0..5)
    if xx < 9
      print meter
      print "\b"
      sleep 0.08
    else print x
    end
  end

  print ' '

  # "y" counter
  10.times do |yy|

    meter = rand (0..5)
    if yy < 9
      print meter
      print "\b"
      sleep 0.08
    else print y
    end
  end

  puts

end
