这次我们基于 pygame 来做一个扫雷，我所有的代码都是基于 python 3.6 的。
下面将一下我的实现逻辑
首先，如何表示雷和非雷，一开始有好多状态，后来一想，干脆就做个类吧。
class BlockStatus(Enum):
normal = 1 # 未点
opened = 2 # 已点
mine = 3 # 雷
flag = 4 # 标记雷
ask = 5 # 标记问号
bomb = 6 # 踩中雷
hint = 7 # 被双击周围
double = 8 # 正在被鼠标左右键双击
class Mine:
def __init__(self, x, y, value=0):
self._x = x
self._y = y
self._value = 0
self._around_mine_count = -1
self._status = BlockStatus.normal
self.set_value(value)
def __repr__(self):
return str(self._value)
# return f'({self._x},{self._y})={self._value}, status={self.status}'
def get_x(self):
return self._x
def set_x(self, x):
self._x = x
x = property(fget=get_x, fset=set_x)
def get_y(self):
return self._y
def set_y(self, y):
self._y = y
y = property(fget=get_y, fset=set_y)
def get_value(self):
return self._value
def set_value(self, value):
if value:
self._value = 1
else:
self._value = 0
value = property(fget=get_value, fset=set_value, doc='0:非地雷 1:雷')
def get_around_mine_count(self):
return self._around_mine_count
def set_around_mine_count(self, around_mine_count):
self._around_mine_count = around_mine_count
around_mine_count = property(fget=get_around_mine_count, fset=set_around_mine_count, doc='四周地雷数量')
def get_status(self):
return self._status
def set_status(self, value):
self._status = value
status = property(fget=get_status, fset=set_status, doc='BlockStatus')布雷就很简单了，随机取99个数，从上往下顺序排
class MineBlock:
def __init__(self):
self._block = [[Mine(i, j) for i in range(BLOCK_WIDTH)] for j in range(BLOCK_HEIGHT)]
# 埋雷
for i in random.sample(range(BLOCK_WIDTH * BLOCK_HEIGHT), MINE_COUNT):
self._block[i // BLOCK_WIDTH][i % BLOCK_WIDTH].value = 1
点击一个格子的时候，只要根据点击的坐标，找到对应的 Mine，看它的值是多少，就知道有没有踩中雷
如果没踩中雷的话，要计算周边8个位置中有几个雷，以便显示对应的数字
如果周边有雷，那么显示数字，这个简单，可是如果周边没有雷，那就要显示一片区域，直到有雷出现
这个计算其实也容易，用递归就可以了，如果计算出周围的雷数为0，则递归计算周边8个位置的四周雷数，直到雷数不为0文章来源：https://www.toymoban.com/news/detail-503849.html
