通过Python把学姐照片做成拼图游戏

前言

事情是这样的

马上就快到毕业季了，大四的学姐们快要离校了

你心中那个没有说出口的学姐，你还记得吗

跟着博主，用pygame给你心中那个学姐做一款专属于她的拼图游戏

万一有什么意外收获呢？

先上效果

我用隔壁诗诗学姐的照片，给她做了一个拼图游戏

结果，我自己的拼不出来了

配置环境

安装pygame模块

#pip install pygame
 
ps c:\users\lex> pip install pygame looking in indexes: 
http://mirrors.aliyun.com/pypi/simple requirement already satisfied:
 pygame in f:\develop\python36\lib\site-packages (2.0.1)
 
ps c:\users\lex>

配置文件

cfg.py

配置需要读取的学姐的照片路径、引入游戏引用到的字体及颜色。

'''配置文件'''
import os
 
'''屏幕大小'''
screensize = (640, 640)
'''读取学姐照片'''
picture_root_dir = os.path.join(os.getcwd(), 'resources/pictures')
'''字体路径'''
fontpath = os.path.join(os.getcwd(), 'resources/font/fzstk.ttf')
'''定义一些颜色'''
backgroundcolor = (255, 255, 255)
red = (255, 0, 0)
blue = (0, 0, 255)
black = (0, 0, 0)
'''fps'''
fps = 40
'''随机打乱拼图次数'''
numrandom = 100

引入资源

将诗诗学姐的照片，添加到resources/pictures路径下，

游戏启动时，根据我们在cfg.py中的配置，会自动将该路径的照片

加载成为我们拼图的原材料。

主函数代码

pintu.py

代码结构搞的简单一点。一个配置文件cfg，一个资源路径resources，存放字体和图片。

主函数代码放在这里：

1、定义四个可移动函数，在存在空格的情况下，允许向空格的方向移动。

2、createboard：随机将图片拆分，并且打乱。

3、开始时，随机从图片文件夹获取一张图片：如果想给整个宿舍的学姐做游戏，

就把所有人的照片放进去，这样每次打开，会随机生成一个学姐的照片作为游戏背景。

游戏运行方法

1、开发工具启动

如果你有python开发环境vscode、sublimetext、notepad+、pycharm等等这些环境，可以直接在工具中，运行游戏。

2、命令行运行游戏
