您好我正在制作一个刽子手游戏，您猜测一个随机选择的单词并且您有三轮。每次你赢得一轮比赛你获得10分，但是如果你在10次慷慨的尝试之前没有猜到这个词。你将失去一轮没有获得任何东西。
在你赢得三场刽子手游戏之后，你会看到一个高分形式的新输入文本框输入你的名字以保存你的高分，以便在高分形式上显示并且它已经验证了（意思是用户必须在文本框中至少有一个字符）。这是我的主要问题所在，如果您第一次通过验证，我的输入框将保存您的姓名和积分。但是，如果您没有第一次通过验证但第二次通过验证，则会保存您的姓名，但您的高分将会保存，但只能保存一个点。对不起，我的英语不好，但无论如何，即使第一次验证失败而不是将其更改为1分，仍保留用户得分的分数？这是我的代码（抱歉不好的缩进）：

用户必须在文本框中至少有一个字符
您的代码目前正在 之前保存到文件
-(void) monitorVolumes
{
// Notification for Mountingthe USB device
[[[NSWorkspace sharedWorkspace] notificationCenter]addObserver:self selector: @selector(onVolumeMount:)
name: NSWorkspaceDidMountNotification object: nil];
// Notification for Un-Mountingthe USB device
[[[NSWorkspace sharedWorkspace] notificationCenter]addObserver:self selector: @selector(onVolumeMount:)
name: NSWorkspaceDidUnmountNotification object: nil];
}
-(void) onVolumeMount: (NSNotification*) notification
{
NSLog(@"Volume Mount");
//Code to get path here...
}
-(void) onVolumeUnmount: (NSNotification*) notification
{
NSLog(@"Volume Unmount");
}
在那段代码（已经写入文件）后，您正在尝试验证：
Username = NameInput.Text
Try
File.WriteAllText(AppPath & "/highscore.txt", Username & " " & UScore)
Catch ex As Exception
MsgBox("The file is missing!", MsgBoxStyle.Critical)
End Try
UScore = vbNull
整合代码，只有在验证成功时才写入文件：
If NameInput.Text = "" Then
MsgBox("Enter a name please")
Else
File.WriteAllText(AppPath & "/highscore.txt", Username & " " & UScore)
Me.Close()
MainMenu.Show()
End If
答案 1 :(得分：0)
使用UScore = vbNull，您可能会重置分数，即使NameInput.Text = ""。
所以，而不是
Try
File.WriteAllText(AppPath & "/highscore.txt", Username & " " & UScore)
Catch ex As Exception
MsgBox("The file is missing!", MsgBoxStyle.Critical)
End Try
UScore = vbNull
If NameInput.Text = "" Then
MsgBox("Enter a name please")
Else
File.WriteAllText(AppPath & "/highscore.txt", Username & " " & UScore)
Me.Close()
MainMenu.Show()
End If
将UScore = vbNull放在If语句中
Try
File.WriteAllText(AppPath & "/highscore.txt", Username & " " & UScore)
Catch ex As Exception
MsgBox("The file is missing!", MsgBoxStyle.Critical)
End Try
If NameInput.Text = "" Then
MsgBox("Enter a name please")
Else
File.WriteAllText(AppPath & "/highscore.txt", Username & " " & UScore)
Me.Close()
MainMenu.Show()
UScore = vbNull 'Put it here instead
End If
