为什么代码未将某些资产视为预制件？

Question

我有带蓝色框符号的预制件资产：代码将其视为预制件并对其进行更改：

这是我通过将它们拖到素材资源而创建的预制件：

此代码将在第一个屏幕快照中将刚体添加到预制件，但不会在第二个屏幕快照中将刚性体添加到两个预制件：

这是一个有效的解决方案脚本：我更改了什么：也许我可以使这一切变得更容易和更短，但是可以正常工作！

• [代替包含我现在正在使用EndsWith：

  如果（paths [i] .EndsWith（“。prefab”））

• 添加了局部变量以获取Rigidbody，然后检查它是否为NULL，而不是它是否为NULL：

  var rb = contentsRoot.GetComponent（）;如果（rb == null）
