Query Modified Properties on ObjectOverride

Hi,

I have been able to access the modified components on a PrefabInstance using

Code (CSharp):

1. PrefabUtility.GetPrefabOverrides()

However there doesn't seem to be a way to get *which* fields on the object were changed. I'm currently looking at the ObjectOverride class.

How can I get this information?

 

Digging through the disassembled source code for that method it seems that Unity checks for all of the serialized properties of that instanceObject and checks the prefabOverride value to see if it's overridden or not.
https://docs.unity3d.com/ScriptReference/SerializedProperty-prefabOverride.html

 

Oh man, I didn't know about that property!

Like a fool, I ended up writing a SerializedObject diffing algorithm to find properties that were different than the parent. That definitely seems much cleaner.

 

Disassembling the Unity's editor functions is usually a very good method to see how things are done or should be done. Sometimes it leads you to easy answer, and sometimes to some native calls which means it's not possible to do it by yourself.

 

For sure. I can assure you I am very deep down that rabbit hole.

Oh man, that seems like exactly what I want. Finding these methods sometimes is tricky (especially given how massive PrefabUtility is). Thanks for the pointer!
