Pygame is a game library written using the SDL library. It is a set of Python program modules used to develop game software. SDL, full name Simple DirectMedia Layer, SDL is written in C, but it can also be developed in C. Of course, there are many other languages. Pygame is a library that uses it in Python. pygame allows you to create feature-rich games and multimedia programs in Python programs.

Develop small games

1. Material preparation

First of all, let’s preview the final running interface of the game

Can Python write WeChat games?

According to the game interface, we can Clearly know that you must first prepare game background pictures, airplane pictures, bullet pictures, etc.

2. Code part

Library dependency:

pygame

This game mainly has two py files, the main file plan_main The .py code part is as follows:
