Pygame实战：BOOM!这有一款超刺激的扎气球游戏等你来玩

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，这个不信的话你自己试试？

正文

本文的《扎气球砰砰砰》小游戏原型就是路边的扎气球的游戏撒，基于Pygame做的！

就准备好射出的箭、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的

准备的，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。（如果需要安装软件、激活码或者遇到问题的话可以私信我哈！）

 模块安装：pip install -i https://pypi.douban.com/simple/ +模块名

二、代码演示

这款小游戏总得有6个.py文件组成的，代码比较多啦，这里就只放一点点哈！完整的私信我哈！

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。
