In this impetuous age ： Every time Xiaobian lands in the glory of the king , And every landing stimulates the battlefield Z！

Look at the chat interface inside , All kinds of substitute 、 All kinds of search cp. Xiaobian thinks , We have lost the original intention of playing games .

Next , Xiaobian will lead you back to your childhood , Let's enjoy our original play 4399 Innocence and innocence ！

Today I'll take you to recall your childhood and make a classic Bomber game ！​

1） material

The rules of the game are still clear , I won't introduce more. Those who don't know how to play can baidu ！

First, prepare the corresponding materials ：【 Some of them are as follows 】

​ Bomber main program ：

The starting interface is as follows ：

​ Define map class ：

class mapParser():
	def __init__(self, mapfilepath, bg_paths, wall_paths, blocksize, **kwargs):
		self.instances_list = self.__parse(mapfilepath)
		self.bg_paths = bg_paths
		self.wall_paths = wall_paths
		self.blocksize = blocksize
		self.height = len(self.instances_list)
		self.width = len(self.instances_list[0])
		self.screen_size = (blocksize * self.width, blocksize * self.height)
	''' Draw the map on the screen '''
	def draw(self, screen):
		for j in range(self.height):
			for i in range(self.width):
				instance = self.instances_list[j][i]
				if instance == 'w':
					elem = Wall(self.wall_paths[0], [i, j], self.blocksize)
				elif instance == 'x':
					elem = Wall(self.wall_paths[1], [i, j], self.blocksize)
				elif instance == 'z':

				elif instance == '2':
					elem = Background(self.bg_paths[2], [i, j], self.blocksize)
				else:
					raise ValueError('instance parse error in mapParser.draw...')
				elem.draw(screen)
	''' Randomly obtain an open space '''
	def randomGetSpace(self, used_spaces=None):
		while True:
			i = random.randint(0, self.width-1)
			j = random.randint(0, self.height-1)
			coordinate = [i, j]
			if used_spaces and coordinate in used_spaces:
				continue
			instance = self.instances_list[j][i]
			if instance in ['0', '1', '2']:
				break
		return coordinate
	''' Get the element type according to the coordinates '''
	def getElemByCoordinate(self, coordinate):
		return self.instances_list[coordinate[1]][coordinate[0]]
	''' analysis .map file '''
	def __parse(self, mapfilepath):
		instances_list = []
		with open(mapfilepath) as f:
			for line in f.readlines():
				instances_line_list = []
				for c in line:
					if c in ['w', 'x', 'z', '0', '1', '2']:
						instances_line_list.append(c)
