I think you’ve all played it, or seen it. This fancy little game
Use Python pyGame to implement, very simple.
Today, let’s use Python to implement this fancy little game.
Complete development process
1. Main structure of the project
First of all, sort out the main structure of the project, in fact, look at the main structure, basically clear
Modules: Python class locations defined by the relevant definitions -- game.py: main module res: places referenced images, audio, etc. -- Audios: audio resources -- IMgs: Picture resources -- fonts: cfg.py: main configuration file xxls.py: Main program file requirements. TXT: Python dependencies to importCopy the code
2. Detailed configuration
cfg.py
In the configuration file, you need to introduce the OS module and configure the screen size for opening the game.
SCREENSIZE = (700, XMARGIN = (SCREENSIZE[0] -gridsize * NUMGRID) // 2 YMARGIN = (SCREENSIZE[1] - GRIDSIZE * NUMGRID) // 2 "" get root directory" ROOTDIR = os.getcwd() "" FPS" "FPS = 30Copy the code3, eliminate all graphics loading
Game.py: Part one
Putting the entire project under the umbrella of the entire game.py module, take the code file apart to decode it.
Puzzle spirit class: first of all through the configuration file, get the path of square spirit, loaded into the game.
Define a function for the move() module, which is relatively simple. Between modules, only adjacent modules can move each other.

1. Use the development tool IDE to start
If the development tool IDE environment
For example, VScode, sublimeText, and Notepad +
Pycharm what configured the Python environment
You can run the game directly in the tool.
2. Command line startup
