前言

扫雷是一款益智类小游戏，最早于 1992 年由微软在 Windows 上发行，游戏适合于全年龄段，规则简单，即在最短的时间内找出所有非雷格子且在中间过程中不能踩到雷，踩到雷则失败，需重新开始。

本文我们使用 Python 来实现扫雷游戏，主要用的 Python 库是 pygame。

实现

游戏组成比较简单，主要包括：小方格、计时器、地雷等。

首先，我们初始化一些常量，比如：横竖方块数、地雷数、鼠标点击情况等，如下所示：

BLOCK_WIDTH = 30
BLOCK_HEIGHT = 16
# 块大小
SIZE = 20
# 地雷数
MINE_COUNT = 66
# 未点击
normal = 1
# 已点击
opened = 2
# 地雷
mine = 3
# 标记为地雷
flag = 4
# 标记为问号
ask = 5
# 踩中地雷
bomb = 6
# 被双击的周围
hint = 7
# 正被鼠标左右键双击
double = 8
readied = 1,
started = 2,
over = 3,
win = 4

接着定义一个地雷类，类中定义一些基本属性（如：坐标、状态等）及 get、set 方法，代码实现如下：

class Mine:def __init__(self, x, y, value=0):self._x = xself._y = yself._value = 0self._around_mine_count = -1self._status = normalself.set_value(value)def __repr__(self):return str(self._value)def get_x(self):return self._xdef set_x(self, x):self._x = xx = property(fget=get_x, fset=set_x)def get_y(self):return self._ydef set_y(self, y):self._y = yy = property(fget=get_y, fset=set_y)def get_value(self):return self._valuedef set_value(self, value):if value:self._value = 1else:self._value = 0value = property(fget=get_value, fset=set_value, doc='0:非地雷 1:雷')def get_around_mine_count(self):return self._around_mine_countdef set_around_mine_count(self, around_mine_count):self._around_mine_count = around_mine_countaround_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 = valuestatus = property(fget=get_status, fset=set_status, doc='BlockStatus')

再接着定义一个 MineBlock 类，用来处理扫雷的基本逻辑，代码实现如下：

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 = 1def get_block(self):return self._blockblock = property(fget=get_block)def getmine(self, x, y):return self._block[y][x]def open_mine(self, x, y):# 踩到雷了if self._block[y][x].value:self._block[y][x].status = bombreturn False# 先把状态改为 openedself._block[y][x].status = openedaround = _get_around(x, y)_sum = 0for i, j in around:if self._block[j][i].value:_sum += 1self._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if _sum == 0:for i, j in around:if self._block[j][i].around_mine_count == -1:self.open_mine(i, j)return Truedef double_mouse_button_down(self, x, y):if self._block[y][x].around_mine_count == 0:return Trueself._block[y][x].status = doublearound = _get_around(x, y)# 周围被标记的雷数量sumflag = 0for i, j in _get_around(x, y):if self._block[j][i].status == flag:sumflag += 1# 周边的雷已经全部被标记result = Trueif sumflag == self._block[y][x].around_mine_count:for i, j in around:if self._block[j][i].status == normal:if not self.open_mine(i, j):result = Falseelse:for i, j in around:if self._block[j][i].status == normal:self._block[j][i].status = hintreturn resultdef double_mouse_button_up(self, x, y):self._block[y][x].status = openedfor i, j in _get_around(x, y):if self._block[j][i].status == hint:self._block[j][i].status = normal

我们接下来初始化界面，首先生成由小方格组成的面板，主要代码实现如下

for row in block.block:for mine in row:pos = (mine.x * SIZE, (mine.y + 2) * SIZE)if mine.status == opened:screen.blit(img_dict[mine.around_mine_count], pos)opened_count += 1elif mine.status == double:screen.blit(img_dict[mine.around_mine_count], pos)elif mine.status == bomb:screen.blit(img_blood, pos)elif mine.status == flag:screen.blit(img_flag, pos)flag_count += 1elif mine.status == ask:screen.blit(img_ask, pos)elif mine.status == hint:screen.blit(img0, pos)elif game_status == over and mine.value:screen.blit(img_mine, pos)elif mine.value == 0 and mine.status == flag:screen.blit(img_error, pos)elif mine.status == normal:screen.blit(img_blank, pos)

再接着添加面板的 head 部分，包括：显示雷数、重新开始按钮（笑脸）、显示耗时，主要代码实现如下：

print_text(screen, font1, 30, (SIZE * 2 - fheight) // 2 - 2, '%02d' % (MINE_COUNT - flag_count), red)
if game_status == started:elapsed_time = int(time.time() - start_time)
print_text(screen, font1, SCREEN_WIDTH - fwidth - 30, (SIZE * 2 - fheight) // 2 - 2, '%03d' % elapsed_time, red)
if flag_count + opened_count == BLOCK_WIDTH * BLOCK_HEIGHT:game_status = win
if game_status == over:screen.blit(img_face_fail, (face_pos_x, face_pos_y))
elif game_status == win:screen.blit(img_face_success, (face_pos_x, face_pos_y))
else:screen.blit(img_face_normal, (face_pos_x, face_pos_y))

再接着添加各种点击事件，代码实现如下：

for event in pygame.event.get():if event.type == QUIT:sys.exit()elif event.type == MOUSEBUTTONDOWN:mouse_x, mouse_y = event.posx = mouse_x // SIZEy = mouse_y // SIZE - 2b1, b2, b3 = pygame.mouse.get_pressed()if game_status == started:# 鼠标左右键同时按下，如果已经标记了所有雷，则打开周围一圈；如果还未标记完所有雷，则有一个周围一圈被同时按下的效果if b1 and b3:mine = block.getmine(x, y)if mine.status == opened:if not block.double_mouse_button_down(x, y):game_status = overelif event.type == MOUSEBUTTONUP:if y < 0:if face_pos_x <= mouse_x <= face_pos_x + face_size \and face_pos_y <= mouse_y <= face_pos_y + face_size:game_status = readiedblock = MineBlock()start_time = time.time()elapsed_time = 0continueif game_status == readied:game_status = startedstart_time = time.time()elapsed_time = 0if game_status == started:mine = block.getmine(x, y)# 按鼠标左键if b1 and not b3:if mine.status == normal:if not block.open_mine(x, y):game_status = over# 按鼠标右键elif not b1 and b3:if mine.status == normal:mine.status = flagelif mine.status == flag:mine.status = askelif mine.status == ask:mine.status = normalelif b1 and b3:if mine.status == double:block.double_mouse_button_up(x, y)
