如何在两个方向键被按下时以对角线方式移动物体?怎么做? 我尝试添加ELSEIF语句处理向上和向右在一起,但它仍然向上或权当我一起按他们VB.NET使用键对角移动物体
Private Sub Form1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown
If e.KeyCode = Keys.Right Then
Label1.Location = New Point(Label1.Location.X + 5, Label1.Location.Y)
ElseIf e.KeyCode = Keys.Left Then
Label1.Location = New Point(Label1.Location.X - 5, Label1.Location.Y)
ElseIf e.KeyCode = Keys.Down Then
Label1.Location = New Point(Label1.Location.X, Label1.Location.Y + 5)
ElseIf e.KeyCode = Keys.Up Then
Label1.Location = New Point(Label1.Location.X, Label1.Location.Y - 5)
ElseIf e.KeyCode = Keys.Up And e.KeyCode = Keys.Right Then
Label1.Location = New Point(Label1.Location.X + 5, Label1.Location.Y + 5)
End If
CheckIntersections()
If Label1.Location.Y < 0 Then
Label1.Location = New Point(Label1.Location.X, Me.Height)
ElseIf Label1.Location.Y > Me.Height Then
Label1.Location = New Point(Label1.Location.X, Me.Bottom = 0)
ElseIf Label1.Location.X < 0 Then
Label1.Location = New Point(Me.Width, Label1.Location.Y)
ElseIf Label1.Location.X > Me.Width Then
Label1.Location = New Point(0, Label1.Location.Y)
End If
End Sub
当两个光标键被按下时,你能编码对象的对角线移动吗? – conquistador 2013-03-09 09:21:07
@XtraCode没有任何时间(我远离我的开发系统)。 – Richard 2013-03-09 09:22:02
