导语
前几天，有人私信小编：
说陪女朋友在小广场上面逛街玩儿扎气球：结果一个都没扎破，扎心了老铁。
女朋友都要离家出走了~让我给想想办法：小编只想给你一个表情。
哈哈哈，开玩笑的~于是，为了满足需求，小编做了一个重大决定：熬夜给他做了一款扎气球的小
游戏，可以拿去哄哄女朋友啦~
这游戏做完之后木子已经替大家玩儿过了，这个很棒，不信的话你自己试试？
正文
本文的扎气球小游戏原型就是路边的扎气球的游戏撒，基于Pygame做的！
就准备好射的箭、不同颜色的气球、一张背景图片、然后爆炸的特效就可。哦~对了音乐还是要准备，游戏的话有音乐背景才更有趣哦~
一、准备中
1）素材资料
首先是准备好需要的素材、图片、背景音乐：
2）运行环境
环境安装 本文用到的运行环境：Python3.7、Pycharm社区版2020、Pygame游戏模块部分自带
模块直 接导入不需要安装。
模块安装：
pip install -i https://pypi.douban.com/simple/ +模块名
二、代码演示
这款小游戏总的有6个.py文件组成的，代码比较都啦，这里就只放一点点哈！
主程序运行：
from game import *
def main() :
intro = True
game = Game()
game.loadMusic()
game.readHighScore()
pygame.mixer.music.play(loops=-1)
while intro:
for event in pygame.event.get():
if event.type == pygame.QUIT:
intro = False
game.screen.fill(SKY_BLUE)
game.screen.blit(game.background, game.background_rect)
game.draw.Button(200, 2*game.HEIGHT/3, "PLAY", BRIGHT_GREEN, GREEN, game.gameloop, 150, 100)
game.draw.Button(game.WIDTH/2 - 75, 2*game.HEIGHT/3, "PLAY TIMED", BRIGHT_RED, RED, game.time_restricted, 150, 100)
game.draw.Button(game.WIDTH-350, 2*game.HEIGHT/3, "QUIT", BRIGHT_GREEN, GREEN, quit, 150, 100)
game.draw.draw_text("__ArcuS__", game.WIDTH/2, game.HEIGHT/3, 200, BLUE)
game.draw.draw_text("HIGH SCORE:%d" % (game.highscore), game.WIDTH-400, 50, 30, BLACK)
pygame.display.flip()
game.clock.tick(FPS)
main()
定义的一些常量：桌面背景、音乐等等。

三、效果展示
游戏规则的话：箭会出现在游戏界面底部中间位置，拉动它：即是鼠标左键拉动方向可自己调整，
直接向下拉动然后放箭射中气球即可。射中的越多积累的分数越高哦！
1）截图展示效果——
游戏开始界面如下：
游戏开始界面如下：
扎中气球效果如下：
游戏结束总成绩13分:
2）视频展示效果——
