Python：游戏：扫雷（附源码） - 好文

这次我们基于 pygame 来做一个扫雷，上次有园友问我代码的 python 版本，我说明一下，我所有的代码都是基于 python 3.6 的。

先看截图，仿照 XP 上的扫雷做的，感觉 XP 上的样式比 win7 上的好看多了。

原谅我手残，扫雷基本就没赢过，测试的时候我是偷偷的把雷的数量从99改到50才赢了。。。

代码虽然不多，但加上注释和空行也有350行，另外还有一些图片资源，就不全帖上来了，完整的代码和资源我放到CSDN上了，感兴趣的小伙伴可以去下载一下。下载地址

下面将一下我的实现逻辑。

首先，如何表示雷和非雷，一开始想的是，建立一个二维数组表示整个区域，0表示非地雷，1表示地雷。后来一想不对，还有标记为地雷，标记为问号，还有表示周边雷数的数字，好多状态，干脆就做个类吧
class BlockStatus(Enum): normal = 1 # 未点击 opened = 2 # 已点击 mine = 3 # 地雷 flag
= 4# 标记为地雷 ask = 5 # 标记为问号 bomb = 6 # 踩中地雷 hint = 7 # 被双击的周围 double = 8 #
正被鼠标左右键双击 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._statusdef 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，从上往下顺序排就是了。
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

我们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了。

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，如下图，我只点了当中一下，就出现了那么大一片区域

这个计算其实也容易，只要用递归就可以了，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。
class MineBlock: 　　def open_mine(self, x, y): # 踩到雷了 if
self._block[y][x].value: self._block[y][x].status= BlockStatus.bomb return False
# 先把状态改为 opened self._block[y][x].status = BlockStatus.opened around =
_get_around(x, y) _sum= 0 for i, j in around: if self._block[j][i].value: _sum
+= 1 self._block[y][x].around_mine_count = _sum # 如果周围没有雷，那么将周围8个未中未点开的递归算一遍 #
这就能实现一点出现一大片打开的效果了 if _sum == 0: for i, j in around: if
self._block[j][i].around_mine_count == -1: self.open_mine(i, j) return True def
_get_around(x, y):"""返回(x, y)周围的点的坐标""" # 这里注意，range 末尾是开区间，所以要加 1 return [(i,
j)for i in range(max(0, x - 1), min(BLOCK_WIDTH - 1, x + 1) + 1) for j in
range(max(0, y - 1), min(BLOCK_HEIGHT - 1, y + 1) + 1)if i != x or j != y]

接下来还有一个麻烦的地方，我们经常鼠标左右键同时按下，如果雷被全部标记，则会一下子打开周围所有的格子，如果其中有标记错的，那么不好意思，GAME OVER。

如果没有全标记完，会有一个效果显示周围一圈未被打开和标记的格子
class MineBlock: 　　 def double_mouse_button_down(self, x, y): if
self._block[y][x].around_mine_count == 0: return True self._block[y][x].status =
BlockStatus.double around= _get_around(x, y) sumflag = 0 # 周围被标记的雷数量 for i, j
in _get_around(x, y): if self._block[j][i].status == BlockStatus.flag: sumflag
+= 1# 周边的雷已经全部被标记 result = True if sumflag ==
self._block[y][x].around_mine_count:for i, j in around: if
self._block[j][i].status == BlockStatus.normal: if not self.open_mine(i, j):
result= False else: for i, j in around: if self._block[j][i].status ==
BlockStatus.normal: self._block[j][i].status= BlockStatus.hint return result def
double_mouse_button_up(self, x, y): self._block[y][x].status=
BlockStatus.openedfor i, j in _get_around(x, y): if self._block[j][i].status ==
BlockStatus.hint: self._block[j][i].status= BlockStatus.normal
扫雷的主要逻辑就这么多，剩下来的就是一些杂七杂八的事件了。代码也帖一下吧
