主题: 002.07 MineSweeper - PsSimleGUI 的应用

还是用PySimpleGU来写一个常见的游戏MineSweeper, 其中PySimpleGUI Button没有提供鼠标右键功能下, 自己加了个event handler来处理, 其他没啥好说, 请见下文.

鼠标右键Event Handler

def right_click(self, event): # Right_click handler
 if self.state == 1:
 self.update(3)
 elif self.state == 3:
 self.update(1)
window[b[x][y].key].Widget.bind('<Button-3>', b[x][y].right_click)

游戏方法:

• 鼠标左键点选, 显示数字或炸弹, 数字的意义为'周围有多少颗炸弹'.

• 鼠标右键点选, 以旗子标记自己认为是炸弹的格子, 鼠标左键不可点选显示, 再点选则去除标记.

• 上方记录炸弹总数, 已点到炸弹总数, 以及旗子总数, 后两者数目等于前者时, 游戏结束

游戏目标:

• 以最少数点到的炸弹总数, 完成游戏.
