How to use Python Pygame to realize Racing Games

Today, I would like to share with you how to use Python Pygame to achieve racing games related knowledge points, detailed content, clear logic, I believe that most people still know too much about this knowledge, so share this article for your reference, I hope you can learn something after reading this article, let's learn about it.

1. Environment installation 1) running environment

The running environment used in the article: Python3.7, Pycharm Community Edition 2021, Pygame game module part of the built-in module direct import does not need to be installed.

Module installation: pip install-I https://pypi.douban.com/simple/ + module name

2) material environment

Music background pictures, etc.:

The life value of each racing game is worth three, that is, the end of the game. Avoiding the corresponding car will give you extra points. Key around is the mobile key.

The game begins--

Game interface--

Game over--
