【问题描述】：
首先我宁愿知道为什么会发生这种情况，然后得到修复。知道会让我学习，而剪切和粘贴代码则不会。 （替代修复会非常好，我感谢你，但这让我感到困惑，我想知道为什么）。
设置： 我在地形上方生成了一个原始形状 GO（游戏对象）。这个 GO 有一个刚体，我在上面附加了一个脚本。 Seed.cs 这个类从另一个名为 body 的类继承了几个函数。一旦生成，GO 就会掉落并与地形接触，这就是问题发生的地方。 GO 可以穿过地形，卡在半个里面，跌倒卡住然后被扔出地面，或者如果跌落速度足够慢，只需持续振动即可。
在 GO 上运行场景之前，我尝试将碰撞检测更改为所有三种不同类型，但效果不大。我发现确实有效的是，当场景运行时，我可以将碰撞检测从一个选项更改为另一个选项，我的问题似乎消失了。我可以在 Body 类的 start 函数中进行这个更改，它工作正常。碰撞检测的实际选项与解决问题无关，它只需要我更改它。从 Continuous 到 Discrete 或 Discrete 到 ContinuousDynamic 唯一的事实是我改变了它，这使得问题消失了。
我希望有人知道为什么会这样。如果有帮助，我会扩展 GO。
代码可能看起来像意大利面条，因为这是一个休闲编程，这也是我第一次使用 Unity。
