Python开发一个滑雪小游戏
作者：互联网
大家好，我是Lex 喜欢欺负超人那个Lex
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
不一会，游戏写好了
效果是这样的
一、如何搭建开发环境环境
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二、完整开发流程
1、代码结构
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
2、详细配置
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')3、动画中引用到的图片
4、资源文件
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
5、主程序
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。

四、如何启动游戏
1、开发工具
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。
2、命令行
