我的 python 街机游戏中的重启功能无法正常工作

Question

I´m currently working on a school project, which is a game with Python Arcade. It is my first coding experience so I´m still a beginner. Unfortunately the projekt is due in a few days, which is why I would really appreciate some help!

The basic structure of the game (it´sa jump´n run) is already working and I just need to add a more platforms and enemys, but while trying to make a restart function, I have encountered a problem. After the game is won or over, it is supposed to restart. Resetting the player and enemys works, but the game is stuck then and it isn´t possible to move the player, nor are the enemys moving. I suppose that after restarting, the game doesn´t call the update function for some reason, but that is just my assumption and I honestly don´t know what the problem is.

您有一个setup功能，您还应该有一个拆卸功能，可以在您的代码中的特定条件下重新启动游戏
