[SOLVED]Playing scene populate with a custom script editor remove all gameobjects

Hello,

I've have a weird editor behavior on my project, that I think is new (I don't remember seeing same behavior before my project upgrade to unity 2018, from u2017).

I've got a custom editor script which create a MenuItem. When script is executed, it remove all scene's gameobject and load others base on a json file that describe a level. Problem is that once the scene is populated, playing it in editor launch the default unity scene (the one load on "New scene" action).

Sometime unity display this message :
"Scene(s) Have Been Modified
Do you want to save the changes you made in the scenes:
Untitled

Your changes will be lost if you don't save them.

"

But I can't find for now the usecase that trigger it.

It make me think about a scene serialization point but it's just an intuition.

Thank for your help

 

does your editor script registers the modifications via

Undo

, or at least calls

SetDirty

? if not, when you start play mode, Unity will load the scene without knowing that you modified it.

 

Thank for your reply, but I solved my problem by :

1. Creating an empty unity 2018 project (project "B")
2. Copy and past my project (project "A") Asset & ProjectFolder directories to project B (here I realised that my custom script was OK and playing scene do not remove anymore gameobjects)
3. Delete all files and directory of my project A
4. Copy and past Asset & ProjectFolder directories of project B to project A
5. And now it work as expected !
