很多小伙伴学习编程的目的就是为了开发游戏。但是我们刚开始学习python编程的时候并不会涉及到游戏开发，再往后如果不是专门往游戏开发方向走的话也不会学习游戏开发相关的知识，这不免有些令人遗憾。今天小编带来一个python滑雪小游戏的源代码，逻辑简单代码易学，有感兴趣的小伙伴赶紧代码跑起来吧！
一、效果图
二、必要工具
Python3.7
pycharm2019
再然后配置它的文件，设置游戏屏幕的大小，图片路径。
代码如下
'''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(), 'resources/images/skier_forward.png'),
os.path.join(os.getcwd(), 'resources/images/skier_right1.png'),
os.path.join(os.getcwd(), 'resources/images/skier_right2.png'),
os.path.join(os.getcwd(), 'resources/images/skier_left2.png'),
os.path.join(os.getcwd(), 'resources/images/skier_left1.png'),
os.path.join(os.getcwd(), 'resources/images/skier_fall.png')
]
OBSTACLE_PATHS = {
'tree': os.path.join(os.getcwd(), 'resources/images/tree.png'),
'flag': os.path.join(os.getcwd(), 'resources/images/flag.png')
}
'''背景音乐路径'''
BGMPATH = os.path.join(os.getcwd(), 'resources/music/bgm.mp3')
'''字体路径'''
FONTPATH = os.path.join(os.getcwd(), 'resources/font/FZSTK.TTF')
三、全部源码
'''滑雪者类'''
