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，我是梦雅，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 = 640SCREENHEIGHT = 480BRICKWIDTH = 10BRICKHEIGHT = 10PADDLEWIDTH = 60PADDLEHEIGHT = 12BALLRADIUS = 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 randomimport 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! You fail!'
text2 = 'Press to restart the game'
text3 = 'Press to quit the game.'
clock = pygame.time.Clock()
while True:

pygame.display.flip()
clock.tick(30)
4）定义游戏

def __init__(self, cfg, **kwargs):
pygame.init()
pygame.display.set_caption('Breakout clone ') pygame.mixer.init()
self.screen = pygame.display.set_mode((cfg.SCREENWIDTH, cfg.SCREENHEIGHT))

score = 0
num_lives = 2
# running: 游戏正在进行, fail: 游戏失败, win: 游戏成功.
state = 'running'
paddle = Paddle((self.cfg.SCREENWIDTH-self.cfg.PADDLEWIDTH)/2,
self.cfg.SCREENHEIGHT-self.cfg.PADDLEHEIGHT-10, self.cfg.PADDLEWIDTH,
self.cfg.PADDLEHEIGHT, self.cfg.SCREENWIDTH,

brick_sprites = pygame.sprite.Group()
brick_positions = loadLevel(levelpath)
for bp in brick_positions: brick_sprites.add(Brick(bp[0]*self.cfg.BRICKWIDTH, bp[1]*self.cfg.BRICKHEIGHT, self.cfg.BRICKWIDTH, self.cfg.BRICKHEIGHT))
clock = pygame.time.Clock()
while True:
if state != 'running':
return state
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit(-1)
keys_pressed = pygame.key.get_pressed()
if keys_pressed[pygame.K_LEFT]:
paddle.move('left')
elif keys_pressed[pygame.K_RIGHT]: paddle.move('right')
self.screen.fill(self.cfg.AQUA)
is_alive = ball.move()
# 判断有没有接住球
if not is_alive:
ball.reset()
paddle.reset()
num_lives -= 1
if num_lives == 0:
state = 'fail'
# 球和砖块碰撞检测
num_bricks = pygame.sprite.spritecollide(ball, brick_sprites, True)
score += len(num_bricks)
# 球和拍碰撞检测
if pygame.sprite.collide_rect(ball, paddle):
ball.change()
# 判断砖块是否已经打完
if len(brick_sprites) == 0:
state = 'win'
# 将游戏精灵绑定到屏幕
paddle.draw(self.screen, self.cfg.PURPLE) ball.draw(self.screen, self.cfg.WHITE)
for brick in brick_sprites:
brick.draw(self.screen, self.cfg.YELLOW)
text_render = self.font_small.render('SCORE: %s, LIVES: %s' % (score, num_lives),
False, self.cfg.BLUE)
self.screen.blit(text_render, (10, 10))
pygame.display.flip()
clock.tick(50) '''关卡切换'''
def __nextLevel(self):
clock = pygame.time.Clock()
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit(-1)
if event.type == pygame.KEYDOWN and event.key == pygame.K_RETURN:
return
self.screen.fill(self.cfg.AQUA)
text = 'Press to enter the next level'
text_render = self.font_big.render(text, False, self.cfg.BLUE) self.screen.blit(text_render, ((self.cfg.SCREENWIDTH-text_render.get_rect().width)//2, (self.cfg.SCREENHEIGHT-text_render.get_rect().height)//3))
pygame.display.flip()
clock.tick(30)
5）主函数与运行界面
