Powershell中的颜色猜测游戏

Question

我正在PowerShell中编写一个颜色猜测游戏的脚本。电脑随机选择一种颜色，然后玩家尝试猜测颜色。我一直在努力，直到我在脚本中切换了几行代码，试图让这两个变量正确显示。现在，我无法让代码运行到玩家声明是否想玩游戏的地步。我当前的错误是do循环，控制台看不到我有while循环，因此抛出一个错误，不会运行其余的代码。

我设法用Visual Studio Code的格式文档功能修复了格式设置，但在解决循环问题时仍然无法修复。

Write-Host ''; 'Hello again my friend!'; ''
$name = Read-Host "What is your name?"
Write-Host ''; "It's good to see you again, $name! Would you like to guess my favorite color?"; ''
$command = Read-Host @'
"How do you answer? (Yes or No?)"
1. Yes (y)
2. No (n)
3. Quit (q)
Enter Choice
'@
switch -Wildcard ($command) {
'Y' { 'Yes!'; '' } 
{ $_ -eq 'y' -or $_ -like 'Ye*' } {
Write-Host "This will be fun! Let us begin!"
Break
}
'N' { 'No!'; '' }
{ $_ -eq 'n' -or $_ -like 'No*' } {
Write-Host "That's too bad, perhaps another day!"
Exit
}
'Q' { 'Quit'; '' }
{ $_ -eq 'q' -or $_ -like 'qu*' } {
Write-Host 'So long!'
Exit
}
default {
'Invalid Command, Please start over.'
Exit
}
}
[string]$playagain = 'y'
[int]$playerwins = 0
[int]$compwins = 0
[int]$totalguesses = 0
[int]$playergames = 0
[int]$compgames = 0
[int]$round = 1
[int]$game = 1
$cpuchoice = $color

while ($playagain -eq 'y') { 
Write-Host ''; "Game $game!"; ''
$cpuchoice = @([System.Enum]::GetValues([System.ConsoleColor])) | Get-Random -Count 1

do {
Write-Host "Round $round! What is my favorite color?"; ''
$listcolor = Read-Host "Would you like to see a list of available colors? Choose 'y' for yes, and 'n' for no."
if ($listcolor -eq 'y') {
[System.Enum]::GetValues([System.ConsoleColor])
}
elseif ($listcolor -eq 'n') {
Write-Host "Suit yourself, let's start."
}
else {
Write-Host "Your choice was invalid. Please choose 'y' for yes, or 'n' for no."
}
do {
$playerchoice = Read-host "Enter your guess"
} while (([System.Enum]::GetValues([System.ConsoleColor])) -notcontains $playerchoice) {
if ($playerchoice -eq $cpuchoice ) {
Write-Host "You win, my favorite color is $cpuchoice." -ForegroundColor $cpuchoice; ''
$playerwins = $playerwins + 1
$totalguesses = $totalguesses + 1
}
elseif ($playerchoice -ne $cpuchoice ) {
Write-Host "You lose, try again."; ''
$playerguesses += $playerchoice
$playerguesses = $playerguesses.Split(',')
$totalguesses = $totalguesses + 1
Write-Host "Here are your guesses so far: "
$playerguesses
''
} 
$round = $round + 1         
}                               
until($playerwins -eq 1) {
$playergames = $playergames + 1
Write-Host "You've won this round and have won $playergames games." -ForegroundColor Green
Write-Host "Your total guesses: $totalguesses."
Write-Host "Your wins - $playergames" -ForegroundColor Yellow
Write-Host "Computer wins - $compgames" -ForegroundColor Yellow
''
}
$playagain = Read-Host "I enjoyed this game. Would you like to challenge again, $name? Y or N"
while (("y", "n") -notcontains $playagain) {
if ($playagain -eq "y") {
Write-Host "I look forward to our next battle!"; ''
$playerwins = 0
$compwins = 0
$game = $game + 1
}
elseif ($playagain -eq "n") {
Write-Host "Thank you for playing!"
exit
}
}
}        
}                                 

导致错误的do循环是以"do"开头的循环；写入主机"；圆形$圆形"在第一个while语句之后。

感谢您的帮助！谢谢

您的程序被解析如下：

while ($playagain -eq 'y')
{ 
# do loop #1
do
{
# do loop #2
do {
}
while (([System.Enum]::GetValues([System.ConsoleColor])) -notcontains $playerchoice)
# floating script block #1
# (doesn't execute the scriptblock, but it gets sent to the output stream instead)
{
if ($playerchoice -eq $cpuchoice ) {
... etc ...
}
# try to invoke a cmdlet "until" with 2 parameters
# i.e. ($playerwins -eq 1) and { ... }
until ($playerwins -eq 1) {
$playergames = $playergames + 1
... etc ...
}
# while loop #1
while (("y", "n") -notcontains $playagain) {
...
}
}

}

错误告诉您第一个do(do loop #1(没有尾随的while或until。

由于存在许多问题(例如，floating script block #1、悬挂的until和while\until-无do(，我无法提供明确而简单的修复方法来使您的代码运行时不会出现重大返工，但这就是当前错误所说的。。。
