很抱歉，如果这是一个重复的问题，我也想提前为我的代码的可怕结构道歉。我只是为了一个爱好编程，并开始这个程序只是为了在我正在研究的另一个游戏中使用的随机地图。这很可怕我知道我没有课，甚至没有一个功能。我真的只是在探索如何制作一张随机地图，它变成了如何滚动这张地图，我如何让它适合屏幕，然后当我碰到两侧时该怎么办...我真的被困在在我把它变成我真正想要的是角落之前。我可以四处移动我的播放器但是如果我向左侧移动然后向上移动到一个角落，我最终会回到屏幕中间，而不是在屏幕的中央顶部滚动。我想提前感谢您的帮助，这里是代码。

答案 0 :(得分：0)
再次抱歉这个程序写得多乱，我更多地玩pygame试图学习如何使用它比什么都重要。在过去的几天里，我一直很忙，一看到这个，答案就让我脸红了。我故意这样做，所以如果玩家已经在顶部或底部，玩家将不会重新进入，但这是我更改了edge_x的布尔值的相同代码块。因此，我所要做的就是返回并添加一个if语句，以确保它已经变为true，如果它已经位于不同的边缘。
