如何在纸牌游戏中翻牌？

Question

我已经创建了一个纸牌游戏，其中2 x 12个不同的图像将加载到24个图片框中的vb形式。我的意图是让用户一次翻两张牌，试图找到要匹配的对。每次加载游戏时，都会有不同的图片，它们会出现在不同的位置。到目前为止，我已经成功地在游戏中加载了卡片背面的图像，但我无法翻转它们来查看我的图像是否已成功加载。我还不关心洗牌，我只是想看看图像是否已经加载，并能够有两张卡在同一时间翻转。我真的很困惑，因为我不习惯使用VB来完成这样的任务，所以任何帮助都是非常感谢的。下面是我的代码：

    'Take images from file

        Dim nums = Enumerable.Range(1, 12).ToArray()

Answer 1

我没有评论的要点，但是你是点击图片来翻页的吗？如果是这样的话，我认为你只需要有一个像下面这样的事件来加载卡片图像的背面。

Private Sub PictureBox1_Click(sender As System.Object, e As System.EventArgs) Handles PictureBox1.Click
    PictureBox1.ImageLocation = ("Path to Picture of back of the card")
    PictureBox1.Load()
End Sub

不要试图过多地考虑这一点--忘记“把它们翻过来”只是简单地改变图像：

    Private Sub PictureBox1_Click(sender As System.Object, e As System.EventArgs) Handles PictureBox1.Click, PictureBox2.Click 'etc
    dim index as short
    ' to do: get the index of the PictureCard
    If sender.Image is coverImg then
        sender.Image = imgs(index) ' in stead of 0, use the index of the picture card
    Else
        sender.Image = coverImage
    End if
End Sub
