如何用Python代码实现滑雪小游戏

本篇内容主要讲解"如何用Python代码实现滑雪小游戏"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"如何用Python代码实现滑雪小游戏"吧!

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')
