编程Ruby老虎机游戏

概述我正在尝试用 Ruby创建一个老虎机游戏,这是我已经得到的.它仍然无法运行,并说最后一行有错误,我不知道是什么或如何解决它. 我需要它有一个类似于这样的输出： How much total money would you like to play with today? 25 Total cash: $25 How much would you like to bet? 10 Cherry – O 我正在尝试用 Ruby创建一个老虎机游戏,这是我已经得到的.它仍然无法运行,并说最后一行有错误,我不知道是什么或如何解决它.

我需要它有一个类似于这样的输出：

How much total money would you like to play with today? 25
Total cash: $25
How much would you like to bet? 10
Cherry – Orange – Orange
You have won $20
Would you like to continue? (yes to continue) yes
Total cash: $35
How much would you like to bet?
etc…

我已经在那里设置了奖金,就像你拿到两个,你赢了两次你的赌注,如果你赢了三个,你赢了三次你的赌注.

但我得到错误：33：语法错误,意外的$end,期待kEND现金=现金奖金

我的代码有什么问题,我该如何解决？

def multiplIEr(s1,s2,s3)          if s1 == s2 and s2 == s3:            multiplIEr = 3          elsif s1 == s2 or s2 == s3 or s1 == s3:            multiplIEr = 2          else            multiplIEr = 0;          return multiplIEr    def main()    slotimageList = ['Cherry','Orange','Plum','Bell','Melon','bar']    cash = gets    puts "How much total money would you like to play with today? " +cash    while True:        puts("Total cash:  $",cash)        bet = gets        puts "How much would you like to bet? " +bet    cash = (cash - bet)    slotimage1 = slotimageList.sample    slotimage2 = slotimageList.sample    slotimage3 = slotimageList.sample    puts "slotimage1"," - ","slotimage2","slotimage3"    winnings = bet * multiplIEr(slotimage1,slotimage2,slotimage3)    puts "You have won $" +winnings    cash = cash + winnings    cont = gets    puts "Would you like to continue? (yes to continue) " +cont    if cont != "yes":        puts "You have ended with $" +cash    else        puts " "    end

解决方法 当您看到消息时：

unexpected $end,expecting kEND

你可以将它翻译成“我到达文件结尾(”$end“),但我没想到,因为我还在等待结束语.”这意味着您忘记键入至少一个配对的末尾,并且您需要检查代码并确保它正确缩进,以便您可以直观地匹配语句.

以下是修复代码正确的结果.在某些地方你似乎使用缩进来关闭一个块(比如Python)而不是正确的语法.

如果我对它采取更多的自由,这就是我可以写它的方式：
