Saving prefab after ContextMenu change

Hello,

I just started using the new prefab workflow and i noticed, if i change a prefab over a ContextMenu command, the following change appears correctly in the hierarchy and inspector, but after leaving the prefab view. It get's lost.

Project sceanrio:
In open prefab view, a context menu reads the transform and saves the values into a struct that is marked as Serializable. Hierarchy and inspector shows value. Leaving the prefab view and open it again shows the old values.

Auto save is enabled.
It only saves the changes that are made by hand.

Am i doing something wrong?

 

The problem is, i am not using a custom inspector or any kind of editor extension, it is only the context menu. Here the link to docs.
https://docs.unity3d.com/ScriptReference/ContextMenu.html

I already tried MarkSceneDirty for another feature and it worked correctly.

I made a little test. This is the script. Even with empty project i can reproduce this, dont know if this is a bug or a feature

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PrefabContextMenuSave : MonoBehaviour
6. {
7.     public Transform OwnTransform;
8.  
9.     [ContextMenu("DoSomething")]
10.     private void DoSomething()
11.     {
12.         this.OwnTransform = this.transform;
13.     }
14. }

Steps:
Attach this script to a gameobject.
Make gameobject prefab.
Open prefab, goto prefab view.
Execute ContextMenu command via Inspector.
See the change happen.
Leave the Prefab view.
Enter it again the change is not saved.

 

That doesn't matter, you still need to use one of the approaches Steen mentioned in order for changes to be saved.

 

So I need to use EditorSceneManager.MarkSceneDirty? That would always include the Editor Namespace in a script as well as the handling during builds to ignore the namespace.

 

Hmm, right. You can use something like this:

Code (CSharp):

1. #if UNITY_EDITOR
2. UnityEditor.SceneManagement.EditorSceneManager.MarkSceneDirty(gameObject.scene);
3. #endif

 

hi, i'm having same problem too.
i created a simple UI Text and changed it's text from context menu and it worked without any problem.
when i created prefab from that UI Text and tried to change it again, the text value changed. but when i enter play mode the change was replaced with the value from the prefab. i tried making scene dirty but it still didn't work.

 

found the solution. had to record prefab modification too.

UnityEditor.PrefabUtility.RecordPrefabInstancePropertyModifications(GetComponent<Text>());
