PyGame做了一个扫雷

效果

 

 

• 绿色的F表示右键点击插旗的地方
• 红色的格子表示点击到了地雷

原理

主时间循环

基本上GUI应用都会有一个主循环，用来接收各种事件，并按照时间类型进行不同的处理。

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

while True:     for event in pygame.event.get():         if event.type == pygame.MOUSEBUTTONUP:             if game.is_over():                 init_game(30)                 continue             pos = event.pos             if event.button == 1:                 game.clicked(pos)             elif event.button == 3:                 game.right_clicked(pos)             # 获取当前那个格子被点击了         if event.type == pygame.QUIT:             sys.exit(0)         pygame.display.update()

主要自定义处理类 

• class Game 
• class Square 

Game

表示一次游戏。当前游戏中所有的地雷分布；保存所有的格子信息；以及每个格子周围的地雷数量。Game点击后需要判断是否是否游戏结束。

如何获胜：

• 所有的雷都被标注
• 已经没有空白的格子可以点了

Square

表示一个格子，初始化的时候会传入是否包含地雷的信息，格子作为一圈的地雷数量。

Square本身含有一个状态机，根据点击状态和点击方式画出各种样式（空白，带数字，F，红色）等。

 

主循环中的事件会传给Game，最终根据位置传个某个Square。

PyGame

pygame.Screen 使用pygame.display.set_mode返回一个画布，然后可以将各种Rect，font之类的放到这画布上。

?

1	pygame.display.set_mode((total_width, total_height))

pygame.Rect 输出格子

pygame.font 输出字体

 

重点方法

• pygame.Screen.blit 将绘制的内容叠放到屏幕上。

?

1 2 3 4

self.face = pygame.Surface((self.rect.width, self.rect.height)) self.face.fill('white') game.get_screen().blit(self.face, (self.rect.left, self.rect.top)) pygame.draw.rect(self.surface, 'gray', self.rect, 1)

• pygame.display.update 刷新页面
