程序O带你回忆经典原生Python开发一款打砖块儿小游戏

　　导语
　　嘿！前不久刚刚给大家 过一款反弹球的小游戏嘛！
　　不知道大家还记得不？不记得可以看下往期的内容呢，在上一期的基础上升级了这款大转款的小游
　　戏，界面的话也挺简单的，经典配色原汁原味哈哈哈。
　　大家好，我是木木子，一个上的编程下的厅堂的女码农！今天带大家编写一款经典的打砖块儿小游戏！
　　小科普：
　　打砖块最早是由雅达利公司开发的一款独立游戏，也是无数人的童年记忆。
　　在谷歌图片中搜索＂atari breakout＂（雅利达打砖块游戏），搜索结果就会变成这款游戏。把所有砖
　　块都清除后，还能继续进入下一轮挑战。
　　大家也可以试试 哈哈哈~希望给大家介绍更多编程方各种知识！
　　正文
　　一、准备中
　　1）游戏规则：
　　把所有砖块都清除后，还能继续进入下一轮挑战
　　初始化每个玩家2次机会，打完所有砖块儿即可胜利，否则失败游戏不过关！
　　（关卡素材、背景音乐等比较少也不展示了需要的主页源码基地见哈）
　　2）环境安装
　　本文用到的环境：Python3、Pycharm、Pygame模块以及部分自带。
　　环境安装：pip install -i https://pypi.douban.com/simple/ +模块名
　　二、开始敲代码
　　1）配置文件
　　import os  ＂＂＂游戏界面一些数值＂＂＂ SCREENWIDTH = 640 SCREENHEIGHT = 480 BRICKWIDTH = 10 BRICKHEIGHT = 10 PADDLEWIDTH = 60 PADDLEHEIGHT = 12 BALLRADIUS = 8 ＂＂＂游戏素材路径＂＂＂ FONTPATH = os.path.join(os.getcwd(), ＂resources/font/font.TTF＂) HITSOUNDPATH = os.path.join(os.getcwd(), ＂resources/audios/hit.wav＂) BGMPATH = os.path.join(os.getcwd(), ＂resources/audios/bgm.mp3＂) LEVELROOTPATH = os.path.join(os.getcwd(), ＂resources/levels＂) LEVELPATHS = [os.path.join(LEVELROOTPATH, ＂%s.level＂ % str(i+1)) for i in range(len(os.listdir(LEVELROOTPATH)))] ＂＂＂一些颜色＂＂＂ BLACK = (0, 0, 0) WHITE = (255, 255, 255) PINK = (212, 149, 174)  PURPLE = (168, 152, 191) YELLOW = (245, 237, 162) BLUE  = (51, 170, 230) AQUA = (182, 225, 225)
　　2） 定义一些类
　　import random import pygame   ＂＂＂板子＂＂＂ class Paddle(pygame.sprite.Sprite):     def __init__(self, x, y, width, height, SCREENWIDTH, SCREENHEIGHT, **kwargs):         pygame.sprite.Sprite.__init__(self)         self.init_state = [x, y, width, height]         self.rect = pygame.Rect(x, y, width, height)         self.base_speed = 10         self.SCREENWIDTH = SCREENWIDTH         self.SCREENHEIGHT = SCREENHEIGHT     ＂＂＂移动板子＂＂＂     def move(self, direction):         if direction == ＂left＂:             self.rect.left = max(0, self.rect.left-self.base_speed)         elif direction == ＂right＂:             self.rect.right = min(self.SCREENWIDTH, self.rect.right+self.base_speed)         else:             raise ValueError(＂Paddle.move.direction unsupport %s...＂ % direction)         return True     ＂＂＂绑定到屏幕上＂＂＂     def draw(self, screen, color):         pygame.draw.rect(screen, color, self.rect)         return True     ＂＂＂重置＂＂＂     def reset(self):         self.rect = pygame.Rect(self.init_state[0], self.init_state[1], self.init_state[2], self.init_state[3])         return True   ＂＂＂球＂＂＂ class Ball(pygame.sprite.Sprite):     def __init__(self, x, y, radius, SCREENWIDTH, SCREENHEIGHT, **kwargs):         pygame.sprite.Sprite.__init__(self)         self.init_state = [x, y, radius*2, radius*2]         self.rect = pygame.Rect(x, y, radius*2, radius*2)         self.base_speed = [5, 5]         self.direction = [random.choice([1, -1]), -1]         self.radius = radius         self.SCREENWIDTH = SCREENWIDTH         self.SCREENHEIGHT = SCREENHEIGHT     ＂＂＂移动球＂＂＂     def move(self):         self.rect.left += self.direction[0] * self.base_speed[0]         self.rect.top += self.direction[1] * self.base_speed[1]         if self.rect.left <= 0:             self.rect.left = 0             self.direction[0] = -self.direction[0]         elif self.rect.right >= self.SCREENWIDTH:             self.rect.right = self.SCREENWIDTH             self.direction[0] = -self.direction[0]         if self.rect.top <= 0:             self.rect.top = 0             self.direction[1] = -self.direction[1]         elif self.rect.bottom >= self.SCREENHEIGHT:             return False         return True     ＂＂＂改变运动速度和方向(与拍相撞时)＂＂＂     def change(self):         self.base_speed = [random.choice([4, 5, 6]), random.choice([4, 5, 6])]         self.direction = [random.choice([1, -1]), -1]         return True     ＂＂＂绑定到屏幕上＂＂＂     def draw(self, screen, color):         pygame.draw.circle(screen, color, (self.rect.left+self.radius, self.rect.top+self.radius), self.radius)         return True     ＂＂＂重置＂＂＂     def reset(self):         self.rect = pygame.Rect(self.init_state[0], self.init_state[1], self.init_state[2], self.init_state[3])         return True   ＂＂＂砖块＂＂＂ class Brick(pygame.sprite.Sprite):     def __init__(self, x, y, width, height, **kwargs):         pygame.sprite.Sprite.__init__(self)         self.init_state = [x, y, width, height]         self.rect = pygame.Rect(x, y, width, height)     ＂＂＂绑定到屏幕上＂＂＂     def draw(self, screen, color):         pygame.draw.rect(screen, color, self.rect)         return True     ＂＂＂重置＂＂＂     def reset(self):         self.rect = pygame.Rect(self.init_state[0], self.init_state[1], self.init_state[2], self.init_state[3])         return True
　　3)定义开始、结束界面
　　＂＂＂开始界面＂＂＂     def __startInterface(self):         clock = pygame.time.Clock()         while True:             for event in pygame.event.get():                 if event.type == pygame.QUIT or (event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE):                     pygame.quit()                     sys.exit(-1)                 if event.type == pygame.KEYDOWN and event.key == pygame.K_RETURN:                     return             self.screen.fill(self.cfg.AQUA)             text1 = ＂Press  to start the game＂             text2 = ＂Press  to quit the game＂             text_render1 = self.font_big.render(text1, False, self.cfg.BLUE)             text_render2 = self.font_big.render(text2, False, self.cfg.BLUE)             self.screen.blit(text_render1, ((self.cfg.SCREENWIDTH-text_render1.get_rect().width)//2, (self.cfg.SCREENHEIGHT-text_render1.get_rect().height)//4))             self.screen.blit(text_render2, ((self.cfg.SCREENWIDTH-text_render2.get_rect().width)//2, (self.cfg.SCREENHEIGHT-text_render2.get_rect().height)//2))             pygame.display.flip()             clock.tick(30)     ＂＂＂结束界面＂＂＂     def __endInterface(self, is_win):         if is_win:             text1 = ＂Congratulations! You win!＂         else:             text1 = ＂Game Over!

　　4） 定义游戏
