下面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。 FPS = 60GRAVITY = 0.15PI = 3.142 WHITE = (255, 255, 255)BLACK = (0, 0, 0)RED = (200, 0, 0)BRIGHT_RED = (255, 0, 0)GREEN = (0, 200, 0)BRIGHT_GREEN = (0, 255, 0)SKY_BLUE = (0, 255, 255)BLUE = (0, 0, 255)GREEN_YELLOW=(181,255,98)BROWN=(204,102,0)DARK_BROWN=(204,76,0) HIGHSCORE_FILE="highscore.txt"ARROW_IMAGE = "assets/arrow_1.png"BACKGROUND_IMAGE = "assets/background.png" EXPLOSION_SOUND = "assets/boom.wav"CLICK_SOUND = "assets/select.wav"MUSIC_FILE = "assets/tgfcoder-FrozenJam-SeamlessLoop.ogg"VOLUME = 0.2 ARROW_SIZE = (16, 150)BALOON_SIZE = (100, 100)HIT_RADIUS = 15MISSES = 15GAME_TIME = 60定义游戏精灵类等： import pygameimport mathimport randomfrom os import pathfrom constants import * #游戏精灵类class Arrow(pygame.sprite.Sprite):    def __init__(self,game):        pygame.sprite.Sprite.__init__(self)        self.WIDTH = game.WIDTH        self.HEIGHT = game.HEIGHT        self.image_orig = pygame.transform.scale(game.arrow_img, ARROW_SIZE)        self.image_orig.set_colorkey(BLACK)        self.image = self.image_orig        self.rect = self.image.get_rect()        self.rect.centerx = self.WIDTH/2        self.rect.bottom = self.HEIGHT-100        self.rot = 0        self.speedx = 0        self.speedy = 0        self.range = 0        self.max_height = 0        self.release_angle = 0        self.set_vel = False        self.Released = False        self.releasex = self.rect.centerx        self.releasey = self.rect.bottom        self.cy = self.rect.centery        self.game = game     def update(self):        if self.Released:            self.speedy -= GRAVITY            self.rect.bottom -= self.speedy            self.rect.centerx += self.speedx            self.rot = (-math.atan2(self.speedx, self.speedy)*180/3.14) % 360            new_image = pygame.transform.rotate(self.image_orig, self.rot)             old_center = self.rect.center            self.image = new_image            self.rect = self.image.get_rect()            self.rect.center = old_center            #

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--
