请帮助我让它像

每次碰到角都要换位置，一开始是倒立的，碰到角的时候是朝下的。请确保一切正常，请您帮忙，我真的需要帮助。谢谢你们。我需要它在图片框循环移动时设置动画。

您可以尝试调换图片框的高度和宽度，然后旋转里面的图片，达到您想要的效果。

    Dim anm As Integer = 1

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    R1.Left = R1.Left + 2
    animate()
    If R1.Left >= 219 Then
        Dim w = R1.Width
        R1.Width = R1.Height
        R1.Height = w
        Timer1.Stop()
        Timer2.Start（）
    End If
End Sub

Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
    R1.Top = R1.Top + 2
    animate()
    R1.Image.RotateFlip(RotateFlipType.Rotate90FlipNone)
    R1.Refresh()
    If R1.Top >= 202 Then
        Dim w = R1.Width
        R1.Width = R1.Height
        R1.Height = w
        Timer2.Stop()
        Timer3.Start()
    End If
End Sub

Private Sub animate()
    If anm = 1 Then
        R1.Image = Image.FromFile("picture1")
        anm = 2
    ElseIf anm = 2 Then
        R1.Image = Image.FromFile("picture2")
        anm = 3
    ElseIf anm = 3 Then
        R1.Image = Image.FromFile("picture3")
        anm = 4
    ElseIf anm = 4 Then
        R1.Image = Image.FromFile("picture4")
        anm = 1
    End If
End Sub
