Py游戏开发:Pygame自制扫雷小游戏

先看看游戏截图,让同学有游戏的体验!!
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，可以扫码关注我的公众号，后台回复“扫雷”获取源码及资源。
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 = xself._y = yself._value = 0self._around_mine_count = -1self._status = BlockStatus.normalself.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._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')
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.bombreturn False# 先把状态改为 openedself._block[y][x].status = BlockStatus.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# 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 Truedef _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 1return [(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 Trueself._block[y][x].status = BlockStatus.doublearound = _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 = Trueif 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 = Falseelse:for i, j in around:if self._block[j][i].status == BlockStatus.normal:self._block[j][i].status = BlockStatus.hintreturn resultdef 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
