我对编码还很陌生，我想构建一个人工智能。我在这个项目中使用 pygame 和 pytorch。有关解决方案或代码格式的任何提示都会有所帮助！
当我运行测试时，只需一次更新即可完全正常工作。然而，当我让 AI 进行输入时，立方体就会从屏幕上掉下来，玩家的位置迅速正向增加，而玩家位置的速度和 y 则负向增加。我被困住了，因为我不认为是与地板的碰撞导致试运行成功。也许是AI的快速输入？这是该项目的 GitHub - https://github.com/hprymak07/physicals-ai-game

这似乎是一项相当困难的任务。我认为问题出在碰撞上。我对代码做了一些小改动，它仍然不起作用，但现在你可以使用 SPACE 来进行一步。像这样你可以看到，红色矩形向上移动，然后向下移动，一旦接触地面，它就会停止。它似乎处于无限循环中。现在可能更容易找到错误。
