【Python小游戏】俄罗斯方块

摘要：这篇文章主要介绍了使用PyQt5模块来设计一个俄罗斯方块的小游戏。

---

• 游戏示例：如下视频演示了一个简单的游戏界面

• 游戏主要说明：
  俄罗斯方块主要涉及了五个类别19种图形，每个图形为4个小方块组成。功能模块主要包括了显示等级，成绩，修改面板的方块数等。

• 设计思路：
  分为四个类来设计，分别包括：

  • Game类：启动一个游戏

    # Gameclass Game:def __init__(self):    self.__board = Board()

  • Shape类：定义了俄罗斯方块的形状，边界，颜色等参数

    # 形状class Shape:def __init__(self):    # 19种形状：tuple参数分别代表：(形状代号，左、右、上、下边缘距离,类型)    self.num = 19    self.type1 = 1    self.type2 = 2    self.type3 = 3    self.type4 = 4    self.type5 = 5    self.vL = (1, 0, 0, 0, 3, self.type1)    self.hL = (2, 0, 3, 0, 0, self.type1)    self.S = (3, 0, 1, 0, 1, self.type2)    self.lZ = (4, 0, 2, 0, 1, self.type3)    self.ruZ = (5, 0, 1, 1, 1, self.type3)    self.rZ = (6, 0, 2, 1, 0, self.type3)    self.luZ = (7, 0, 1, 0, 2, self.type3)    self.lvuF = (8, 0, 1, 0, 2, self.type4)    self.rvuF = (9, 0, 1, 0, 2, self.type4)    self.lhdF = (10, 0, 2, 0, 1, self.type4)    self.rhdF = (11, 0, 2, 0, 1, self.type4)    self.rvdF = (12, 0, 1, 0, 2, self.type4)    self.lvdF = (13, 0, 1, 2, 0, self.type4)    self.rhuF = (14, 0, 2, 1, 0, self.type4)    self.lhuF = (15, 0, 2, 0, 1, self.type4)    self.uW = (16, 0, 2, 1, 0, self.type5)    self.dW = (17, 0, 2, 0, 1, self.type5)    self.lW = (18, 0, 1, 1, 1, self.type5)    self.rW = (19, 0, 1, 0, 2, self.type5)    self.name = (        (1, 0, 0, 0, 3, self.type1), (2, 0, 3, 0, 0, self.type1),        (3, 0, 1, 0, 1, self.type2), (4, 0, 2, 0, 1, self.type3),        (6, 0, 2, 1, 0, self.type3), (7, 0, 1, 0, 2, self.type3),        (5, 0, 1, 1, 1, self.type3), (8, 0, 1, 0, 2, self.type4),        (13, 0, 1, 2, 0, self.type4), (9, 0, 1, 0, 2, self.type4),        (12, 0, 1, 0, 2, self.type4),        (15, 0, 2, 0, 1, self.type4), (10, 0, 2, 0, 1, self.type4),        (14, 0, 2, 1, 0, self.type4), (11, 0, 2, 0, 1, self.type4),        (16, 0, 2, 1, 0, self.type5), (17, 0, 2, 0, 1, self.type5),        (18, 0, 1, 1, 1, self.type5),        (19, 0, 1, 0, 2, self.type5))    self.color = (QColor(250, 150, 50), QColor(100, 100, 100), QColor(100, 150, 150), QColor(150, 100, 100))    self.num_col = len(self.color)

• 最后：
  总的来说俄罗斯方块实现起来比较方便，是进行PyQt学习的一个不错方式。另外，楼主的想法是接下来完成自动万俄罗斯方块的功能，有感兴趣的小伙伴可以下载代码自己试试看喔。
