前言
今天为大家带来解闷用的过迷宫小游戏分享给大家好了。让我们愉快地开始吧~

开发工具
Python版本: 3.6.4
相关模块:
pygame模块;
以及一些Python自带的模块。
环境搭建
安装Python并添加到环境变量,pip安装需要的相关模块即可。
原理简介
游戏规则:
玩家通过↑↓←→键控制主角行动,使主角从出发点(左上角)绕出迷宫,到达终点(右下角)即为游戏胜利。
逐步实现:
首先,当然是创建迷宫啦,为了方便,这里采用随机生成迷宫的方式(人工设计真的费眼睛,弄到一半不想弄了,有兴趣的可以自行尝试。)。思路其实很简单,就是把游戏界面划分成多个cell,类似这样子:
然后设计算法遍历所有的cell,每个被遍历到的cell在某几个随机的方向上打开一堵墙(就是去掉分割cell的线条)就ok啦~
具体而言,代码实现如下:
\'\'\'随机生成迷宫类\'\'\'
class RandomMaze():
def __init__(self, maze_size, block_size, border_size, **kwargs):
self.block_size = block_size
self.border_size = border_size
self.maze_size = maze_size
self.blocks_list = RandomMaze.createMaze(maze_size, block_size, border_size)
self.font = pygame.font.SysFont(\'Consolas\', 15)
\'\'\'画到屏幕上\'\'\'
def draw(self, screen):
for row in range(self.maze_size[0]):
for col in range(self.maze_size[1]):
self.blocks_list[row][col].draw(screen)
# 起点和终点标志
showText(screen, self.font, \'S\', (255, 0, 0), (self.border_size[0]-10, self.border_size[1]))
showText(screen, self.font, \'D\', (255, 0, 0), (self.border_size[0]+(self.maze_size[1]-1)*self.block_size, self.border_size[1]+self.maze_size[0]*self.block_size+5))
\'\'\'创建迷宫\'\'\'
@staticmethod
def createMaze(maze_size, block_size, border_size):
def nextBlock(block_now, blocks_list):
directions = [\'top\', \'bottom\', \'left\', \'right\']
blocks_around = dict(zip(directions, [None]*4))
block_next = None
count = 0
# 查看上边block
if block_now.coordinate[1]-1 >= 0:
block_now_top = blocks_list[block_now.coordinate[1]-1][block_now.coordinate[0]]
if not block_now_top.is_visited:
blocks_around[\'top\'] = block_now_top
count += 1
# 查看下边block
if block_now.coordinate[1]+1 < maze_size[0]:
block_now_bottom = blocks_list[block_now.coordinate[1]+1][block_now.coordinate[0]]
if not block_now_bottom.is_visited:
blocks_around[\'bottom\'] = block_now_bottom
count += 1
# 查看左边block
if block_now.coordinate[0]-1 >= 0:
block_now_left = blocks_list[block_now.coordinate[1]][block_now.coordinate[0]-1]
if not block_now_left.is_visited:
blocks_around[\'left\'] = block_now_left
count += 1
# 查看右边block
if block_now.coordinate[0]+1 < maze_size[1]:
block_now_right = blocks_list[block_now.coordinate[1]][block_now.coordinate[0]+1]
if not block_now_right.is_visited:
blocks_around[\'right\'] = block_now_right
count += 1
if count > 0:
while True:
direction = random.choice(directions)
if blocks_around.get(direction):
block_next = blocks_around.get(direction)
if direction == \'top\':
block_next.has_walls[1] = False
block_now.has_walls[0] = False
elif direction == \'bottom\':
block_next.has_walls[0] = False
block_now.has_walls[1] = False
elif direction == \'left\':
block_next.has_walls[3] = False
block_now.has_walls[2] = False
elif direction == \'right\':
block_next.has_walls[2] = False
block_now.has_walls[3] = False
break
return block_next
blocks_list = [[Block([col, row], block_size, border_size) for col in range(maze_size[1])] for row in range(maze_size[0])]
block_now = blocks_list[0][0]
records = []
while True:
if block_now:
if not block_now.is_visited:
block_now.is_visited = True
records.append(block_now)
block_now = nextBlock(block_now, blocks_list)
else:
block_now = records.pop()
if len(records) == 0:
break
return blocks_list
```
接下来就是定义角色类啦,角色类需要根据用户的操作进行上下左右的移动,同时,保证移动是不能跨越墙的就OK了~具体而言,代码实现如下:
```python
\'\'\'定义hero\'\'\'
class Hero(pygame.sprite.Sprite):
def __init__(self, imagepath, coordinate, block_size, border_size, **kwargs):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.image.load(imagepath)
self.image = pygame.transform.scale(self.image, (block_size, block_size))
self.rect = self.image.get_rect()
self.rect.left, self.rect.top = coordinate[0] * block_size + border_size[0], coordinate[1] * block_size + border_size[1]
self.coordinate = coordinate
self.block_size = block_size
self.border_size = border_size
\'\'\'移动\'\'\'
def move(self, direction, maze):
blocks_list = maze.blocks_list
if direction == \'up\':
if blocks_list[self.coordinate[1]][self.coordinate[0]].has_walls[0]:
return False
else:
self.coordinate[1] = self.coordinate[1] - 1
return True
elif direction == \'down\':
if blocks_list[self.coordinate[1]][self.coordinate[0]].has_walls[1]:
return False
else:
self.coordinate[1] = self.coordinate[1] + 1
return True
elif direction == \'left\':
if blocks_list[self.coordinate[1]][self.coordinate[0]].has_walls[2]:
return False
else:
self.coordinate[0] = self.coordinate[0] - 1
return True
elif direction == \'right\':
if blocks_list[self.coordinate[1]][self.coordinate[0]].has_walls[3]:
return False
else:
self.coordinate[0] = self.coordinate[0] + 1
return True
else:
raise ValueError(\'Unsupport direction <%s> in Hero.move...\' % direction)
\'\'\'绑定到屏幕\'\'\'
def draw(self, screen):
self.rect.left, self.rect.top = self.coordinate[0] * self.block_size + self.border_size[0], self.coordinate[1] * self.block_size + self.border_size[1]
screen.blit(self.image, self.rect)
```
最后,就是写下游戏主循环,这个其实也很简单,只要每次载入一个随机生成的迷宫地图和实例化一个主角,然后不断进行按键检测,并根据按键检测的结果移动主角,最后根据行动结果更新界面数据就OK了~当然,若主角到达了终点,则进入关卡切换界面。
具体而言,代码实现如下:
```python
\'\'\'主函数\'\'\'
def main(cfg):
# 初始化
pygame.init()
pygame.mixer.init()
pygame.font.init()
pygame.mixer.music.load(cfg.BGMPATH)
pygame.mixer.music.play(-1, 0.0)
screen = pygame.display.set_mode(cfg.SCREENSIZE)
pygame.display.set_caption(\'Maze - 微信公众号: Charles的皮卡丘\')
font = pygame.font.SysFont(\'Consolas\', 15)
# 开始界面
Interface(screen, cfg, \'game_start\')
# 记录关卡数
num_levels = 0
# 记录最少用了多少步通关
best_scores = \'None\'
# 关卡循环切换
while True:
num_levels += 1
clock = pygame.time.Clock()
screen = pygame.display.set_mode(cfg.SCREENSIZE)
# --随机生成关卡地图
maze_now = RandomMaze(cfg.MAZESIZE, cfg.BLOCKSIZE, cfg.BORDERSIZE)
# --生成hero
hero_now = Hero(cfg.HEROPICPATH, [0, 0], cfg.BLOCKSIZE, cfg.BORDERSIZE)
# --统计步数
num_steps = 0
# --关卡内主循环
while True:
dt = clock.tick(cfg.FPS)
screen.fill((255, 255, 255))
is_move = False
# ----↑↓←→控制hero
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit(-1)
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP:
is_move = hero_now.move(\'up\', maze_now)
elif event.key == pygame.K_DOWN:
is_move = hero_now.move(\'down\', maze_now)
elif event.key == pygame.K_LEFT:
is_move = hero_now.move(\'left\', maze_now)
elif event.key == pygame.K_RIGHT:
is_move = hero_now.move(\'right\', maze_now)
num_steps += int(is_move)
hero_now.draw(screen)
maze_now.draw(screen)
# ----显示一些信息
showText(screen, font, \'LEVELDONE: %d\' % num_levels, (255, 0, 0), (10, 10))
showText(screen, font, \'BESTSCORE: %s\' % best_scores, (255, 0, 0), (210, 10))
showText(screen, font, \'USEDSTEPS: %s\' % num_steps, (255, 0, 0), (410, 10))
showText(screen, font, \'S: your starting point D: your destination\', (255, 0, 0), (10, 600))
# ----判断游戏是否胜利
if (hero_now.coordinate[0] == cfg.MAZESIZE[1] - 1) and (hero_now.coordinate[1] == cfg.MAZESIZE[0] - 1):
break
pygame.display.update()
# 更新最优成绩
if best_scores == \'None\':
best_scores = num_steps
else:
if best_scores > num_steps:
best_scores = num_steps
# 关卡切换
Interface(screen, cfg, mode=\'game_switch\')
