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~

效果图展示

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\')
