Bug [MPPM] Error: found out-of-date assets

The last few days I dealt with a bug which prevented me from starting virtual players in MPPM. I had to manually add a dependency to the Packages/manifest.json to overcome this issue. However, I ran into a new error which prevents MPPM from working. The virtual player now starts, but gives me this error preventing any multiplayer tests from working:

"Asset Database is set to Read Only, but it has found out-of-date assets. This should not happen!"

Any idea what I could do to fix this?

 

This sounds odd. What exactly was that issue and package?


You should try deleting either Library/VP or the entire Library folder. With Unity closed.

 

I had this error today as well. In Unity 6000.0.0b12 with MPPM 1.0.0 (no "pre").

This happened after importing my template asset into a new project. Then activating all three virtual players all at once. I'm guessing that choked the system, and I may have modified the scene. I don't normally do this after having issues before but wanted to give that a try again.

My best bet is to simultaneously enable three virtual players in a fresh project / cleaned Library. Then simultaneously - since that takes a while and one wants to stay busy - edit the open scene or a prefab (try saving them too) while the players are still activating.

I have a feeling this is a bad idea but the system doesn't prevent one from modifying assets while players are activating.

 

Sorry for not providing more information. My bad.

I'm using Unity 2023.2.15f1 and MPPM 0.6.0. The package I had to add a dependency for was A* Pathfinding Project. It is the only package I use that is directly located in the Packages folder.

Even with Stack Trace Logging set to full for everything, I don't get more information regarding this new error. At least the VP compiles and I can actually start the play mode. However, the error comes first and after that I get a bunch of warnings regarding missing scripts on game objects. Needless to say, that it is unplayable.

 

After deleting the whole Library folder I get the same error, but in more detail.

Asset Database is set to Read Only, but it has found out-of-date assets. This should not happen!

Just updated to Unity 6 and MPPM 1.0. I also deleted the Library folder once again.

When I try to activate a virtual player in MPPM the new player window does not even open. But after some time I see that the VP encountered 4 errors, which I can not see in detail and in my console I get this one:

I actually tried to repro this error yesterday having seen it only once or twice by activating multiple players while also editing scenes and prefabs at the same time. Was unable to provoke this issue, but could send a report for other errors I'm getting (particularly: Editor scene load cannot be used in playmode when exiting playmode).

 

Hello @simon-lemay-unity , I'm also getting a "Timeout reached" warning that blocks the instance windows since the MPPM 1.0 release.

I've sent a bug report, but the test-team can't reproduce the bug. There is my entire project + logs if someone of the Unity MPPM team wants to understand the bug.

How to reproduce?
- It seems the bug happens on Windows (it tried on my Mac, no problem)
- On Unity 6 (6000.0.0b13) but also on the Unity 2023.2.16f1
- On Windows 10 (10.0.19045) 64bit (for sure because it is my version)
- On the MPPM 1.0 release (I did not have the bug on the preview)
- When I want to activate a new instance from the MPPM window, it turned activated, but the window instance doesn't display. I have this error in my main editor log :

Code (CSharp):

And on the VP Editor.log, I have this weird entry :

So far I have not encountered a timeout. You may want to try deleting the virtual players' cached data by deleting Library/VP/(every folder) but leave the .json file in the VP folder because that contains your players' tags and roles.

 

already done that, nothing changed. I also tried to completely delete the Library folder. And I tried to remove the packages caches from my AppData. Nothing worked on ANY of my projects using MPPM.

 

Yes my Windows language is set to French. I’ll try to modify the layout and go back to you asap

 

@simon-lemay-unity I opened every SJON Layouts, in every of them, the size is "0.5" (and not "0,5"). Reading the log I previously sent, the bug happened when it tries to WRITE the "Library/UserSettings/Layouts\layout_0010.wlt" file. So, I updated the layout_0010.sjson file to set the size to 1 like that:

Code (JavaScript):

1. restore_saved_layout = true
2. top_view =                 { class_name = "TopView" size = 30 }
3. view = {
4. vertical = true
5.             children = [
6. {
7. tabs = true
8. size = 1
9.             children = [
10.                 { class_name = "GameView" }
11.             ]
12. }
13. {
14. tabs = true
15. size = 1
16.             children = [
17.                 { class_name = "ConsoleWindow" }
18.             ]
19. }
20.             ]
21. }

It didn't work, I think it does not update the package properly if I modify it myself. But the real problem is that my Windows is set to French. And maybe, when it tries to write the file, it converts 0.5 to 0,5 (like readable French float number).

EDIT: I changed my regional format to English and it worked so it seems the bug only happens on regional format that uses "," as decimal (like French). Pls, fix this

 

Sadly, this does not fix my "out-of-date assets" issue. I don't feel comfy giving away my project. I will see if I can reproduce the error. This could take a bit since time is short right now.

 

Even using MPPM 1.0? Did you get both errors (out-of-date and Timeout Reached)?

 

Only the out of date issue and also with MPPM 1.0. I get this error 4 times now. The first 2 and the second 2 are identical with identical timestamp.

Found it! I also sent a bug report and I will inform the developer of A* Pathfinding Project.

Steps to reproduce:

1. Install Unity 6000.0.0b13

2. Install Multiplayer Play Mode 1.0.0

3. Install A* Pathfinding Project Pro 5.0.6

4. Create a new GameObject

5. Attack "RichAI" script to the GameObject.

6. Save this GameObject as a prefab anywhere in your Assets folder.

7. The GameObject can be removed from the scene.

8. Enable a virtual player in Multiplayer play mode.

9. The console of the virtual player should show an error reading: Asset Database is set to Read Only, but it has found out-of-date assets. This should not happen!

 

I just had the same problem. The Unity version is now 6000.0.0f1 and with this fix it worked. When will this be implemented in an update?

 

I think it will never be fixed... I opened an issue in the bug report that has been flagged as "Not Qualified." by
Sebastian Termen (of the QA) because he couldn't reproduce the bug. Until someone in France (or a country with globalization problems) reopens and takes the bug, you will get that bug...

 

When I start a virtual player while not in Play mode, I get the out-of-date error, followed by a few hundred other errors. I see some assets being rendered, but not all.

When I am in Play mode and then start a virtual player, I first get this error: Assertion failed on expression: 'scriptedIMporterClass == SCRIPTING_NULL || uniqueDomainId == MonoDomainGetUniqueId()'
Followed by the out-of-date assets error.
In this case, no graphics are rendered at all.

This is an upgraded project, not a fresh project.

 

still happens in latest unity 6
