Powershell循环直到按键

Question

我一直在编写ps菜单脚本来帮助我使用游戏服务器。

其中一个函数是循环，检查进程是否正在运行，并从文件中获取一些数据。不过我一直试图打破循环回到主菜单，此刻我们必须关闭脚本并重新打开它。

以下是我在网上找到的一些例子中所尝试的内容

 # Guardian Mode, keeps halo online running 
Function guardian {
while ($true) {
cls
if ((Get-Process -Name eldorado -ErrorAction SilentlyContinue) -eq $null) 
{

    Write-Host -ForegroundColor Red "Server Is Not Running" ;

    .\eldorado.exe -launcher -dedicated -headless -window -height 300 -width 300  ;

    "Guardian Started Headless Eldorito Server $($date)" | Add-Content .\dedicatedServer.log 

}
 if ([console]::KeyAvailable)
{
    echo "Press space to go back to mainmenu";
    $x = [System.Console]::ReadKey() 

    switch ( $x.key)
    {
        F12 { $continue = mainmenu }
    } 
    }
else {write-host -ForegroundColor Green "Guardian Mode is Activated, Server Is Running (Checking 15s)" 

         Write-Host -ForegroundColor cyan "Name" ;  (Invoke-WebRequest -Uri 127.0.0.1:11775 | ConvertFrom-Json).Name
         Write-Host -ForegroundColor cyan "Player Count:" ; (Invoke-WebRequest -Uri 127.0.0.1:11775 | ConvertFrom-Json).numPlayers
         Write-Host -ForegroundColor cyan "Variant" ; (Invoke-WebRequest -Uri 127.0.0.1:11775 | ConvertFrom-Json).variant
         Write-Host -ForegroundColor cyan "Map" ; (Invoke-WebRequest -Uri 127.0.0.1:11775 | ConvertFrom-Json).map
         Write-Host -ForegroundColor cyan "GameType" ; (Invoke-WebRequest -Uri 127.0.0.1:11775 | ConvertFrom-Json).variantType
         Write-Host -ForegroundColor cyan "Status" ; (Invoke-WebRequest -Uri 127.0.0.1:11775 | ConvertFrom-Json).status 
        Get-Content .\chat.log -Tail 5
         Write-Host -ForegroundColor cyan "Running Since" ; Get-Content .\dedicatedServer.log -Tail 1
     }

Start-Sleep -Seconds 15

} 
}
