wxpython入门第十一步（俄罗斯方块）[Python基础]

俄罗斯方块是由俄罗斯程序员 Alexey Pajitnov 在1985年设计和编程的。

在这个游戏中，我们有七种不同的形状：S形，Z形，T形，L形，线形，镜面L形，和一个方形。每一个形状都是由四个小正方形组成的。这些形状都是从棋盘上掉下来的。俄罗斯方块游戏的目的是移动和旋转这些形状，使它们尽可能地适合。如果我们成功地形成一排，这一排就会被销毁，我们就会得分。我们玩俄罗斯方块游戏，直到我们达到顶点。

wxPython 是一个用于创建应用程序的工具包。还有一些其他的库比如pygame是针对创建电脑游戏的，但wxPython也可以用来创建游戏。

开发过程

我们的俄罗斯方块游戏没有图像，我们使用wxPython中提供的绘图API绘制俄罗斯方块。每一个电脑游戏的背后，都有一个数学模型。俄罗斯方块中也是如此。

游戏背后的一些基础想法。

  • 用wx.Timer来创建一个游戏循环。

  • 画出不同形状

  • 形状以方块为单位移动（而不是以像素为单位）。

  • 在数学上，棋盘是一个简单的数字列表。

            style=wx.DEFAULT_FRAME_STYLE ^ wx.RESIZE_BORDER ^ wx.MAXIMIZE_BOX)
        self.initFrame()
    def initFrame(self):
