Question

我正在学习如何在java中制作游戏。我很确定我已完全输入所有代码。目标只是在屏幕上显示一个白色的盒子作为播放器，但由于某种原因，白盒子没有显示，我将发布下面的所有课程。

'Dim currentField As String = "Contacts.Address2 as `Contact Address2`"
Dim currentField As String = "CONCAT(Contacts.FirstName;;' ';;Contacts.LastName) as `Contact`"
'Dim currentField As String = "Contacts.ContactID"
Dim myRegex As New Regex("\([^()]+\)")
Dim splitRegex As New Regex("\W+|\s*\bas\b\s*")
Dim mymatch As MatchCollection = myRegex.Matches(currentField)
If mymatch.Count > 0 Then
    For Each match As Match In mymatch
        Dim mysubstrs As String() = splitRegex.Split(match.Value)
        For Each substr As String In mysubstrs
           If String.IsNullOrEmpty(substr) = False Then
                Console.WriteLine(substr)
           End If
        Next
    Next
Else
    Dim mysubstrs As String() = splitRegex.Split(currentField)
        For Each substr As String In mysubstrs
            If String.IsNullOrEmpty(substr) = False Then
               Console.WriteLine(substr)
            End If
        Next
End If

Answer 1

我看不到有人调用启动线程的Game.start()方法。尝试：

public static void main(String args[]){
    new Game().start();
}

白色框未出现在我的屏幕上
