擅长领域:Python开发一个小游戏
今日重点:一步步分析and越过亚马逊的反爬虫机制
效果是这样的
一起来学pygame吧 游戏开发30例(开篇词)——环境搭建+游戏效果展示
windows系统,python3.6+ pip21+
安装游戏依赖模块 pip install pygame
首先,先整理一下项目的主结构,其实看一下主结构,基本就清晰了
modules:自己定义的模块 ——game.py:主程序 res:存放引用到的图片和音频等等 ——music: 音频 资源 ——imgs: 图片 资源 ——fonts: 字体 cfg.py:为主配置文件 skiing.py:主程序文件 requirements.txt:需要引入的python依赖包
cfg.py
配置文件中,需要引入os模块,并且配置打开游戏的屏幕大小。将我们需要用到的图片、音频和字体文件全部引入到项目中。
'''配置文件''' import os '''FPS''' FPS = 40 '''游戏屏幕大小''' SCREENSIZE = (640, 640) '''图片路径''' SKIER_IMAGE_PATHS = [ os.path.join(os.getcwd(), 'res/imgs/game_forward.png'), os.path.join(os.getcwd(), 'res/imgs/game_right1.png'), os.path.join(os.getcwd(), 'res/imgs/game_right2.png'), os.path.join(os.getcwd(), 'res/imgs/game_left2.png'), os.path.join(os.getcwd(), 'res/imgs/game_left1.png'), os.path.join(os.getcwd(), 'res/imgs/game_fall.png') ] OBSTACLE_PATHS = { 'tree': os.path.join(os.getcwd(), 'res/imgs/tree.png'), 'flag': os.path.join(os.getcwd(), 'res/imgs/flag.png') } '''背景音乐路径''' BGMPATH = os.path.join(os.getcwd(), 'res/music/bgm.mp3') '''字体路径''' FONTPATH = os.path.join(os.getcwd(), 'res/font/FZSTK.TTF')
包括游戏背景音频、图片和字体设计
res
music:游戏背景音乐
fonts:记分牌呀、显示呀的 相关字体
imgs:游戏动画里的静态图片,所谓动画都是图片
skiing.py
在主程序中,通过读取配置文件,引入项目资源:包括图片、音频等,并从我们的modules里引入所有我们的模块。

如果你有配置了工具的环境VScode、sublimeText、notepad+、pycharm什么的,可以直接在工具中,运行游戏。
如果没配置,可以使用命令启动。
