我目前正在研究一个学校项目，这是一个使用Python Arcade进行的游戏。这是我的第一次编码经验，所以我还是一个初学者。不幸的是，项目将于几天后到期，这就是为什么我会非常感谢您的帮助！
游戏的基本结构（一次跳跃运行）已经在起作用，我只需要添加更多的平台和敌人，但是在尝试重新启动功能时，我遇到了一个问题。游戏获胜或结束后，应该重新开始。重置玩家和敌人是可行的，但随后游戏被卡住，无法移动玩家，也无法移动敌人。我想重启后，游戏由于某种原因没有调用更新功能，但这只是我的假设，老实说我不知道问题出在哪里。

答案 0 :(得分：0)
您有一个setup函数，还应该有一个拆除函数，该函数可以在代码中的特定条件下重新启动游戏
