The referenced script (Unknown) on this Behaviour is missing!

Hello,

When I play my game in packed mode I have some warnings that are hard to fix because it gives not so much information The warning is : The referenced script (Unknown) on this Behaviour is missing! or something similar.

Here is a screenshot of my console



Thanks !

 

I have the same issue when going back and forth between scenes, both in standalone and editor packed mode. Some objects are randomly missing scripts while instantiating them. The Animator doesn't load properly and sprites end up having the internal error shader (pink). I'm trying to find repro steps to provide a sample projet, without success yet. It started happening when I updated from 0.4.8 to 0.6.7.

 

I managed to remove the warnings by identifying the prefabs that misses script reference, delete them and make new ones. But if I do fix errors with the addressables analyse tool, the warnings are back for the same 3 prefabs, even if it a new one that I re-created.

The game is working in editor but not in the built version

Any idea @unity_bill ? I really need help on this one

On the built version, I can't go from menu scene to the game because I have this "corrupted" prefabs that crash the game.

Here is my log from the build version :

When I delete all the Addressables Duplicate isolation group, the warnings disappeared but I have a

NullReferenceException

during runtime ... Fixing addressables duplicates again fixes the

NullReferenceException

but brings back the warnings described in the initial post ...
Please tell me that this is a know issue and that it will be fixed
@unity_bill you can have access to my project if you need to.
Have a nice day !

 

Two things to check. For one, make sure that you redo "build player content" after doing the duplicate cleanup. Really after doing anything, so ideally do it before you build the player. Secondly, make sure when you do "build player content" it's for the same platform that you're building the player for. If you, for example, were in Android mode, then build addressables, switched to windows, and build the windows player, things would not work.

 

Hello Bill,

I'm building player content every time I want to play or build the game, plus I build only for windows at the time.
I've updated Addressables to 0.7.4 but my issue persists, when I build the game I have these errors that I haven't in any other play mode in the editor ...

Thanks for your support !

 

I'm back

In fact it seems that addressables is not the issue but something that supposed to be corrupted on my unity project ...
i can't open my Level selection panel because it crashes the built game. But If I put a test button to launch a random level anywhere else I can load the level and all is working fine.
How can I hunt the corrupted thing ? Is there any technique or tool to analyse this kind of situation

 

Have you tried deleting the Library folder? It makes your next Unity-launch take a long time, but that's the default fix-it for most weird issues like this.

 

Hey thanks but deleting Library will preserve my collab history ? Last time I did this kind of thing I lost all my collab history ?

 

I had this issue today and after deleting the Library folder, re-launching the project, cleaning the addressables, build player content, the problem was gone.

 

@unity_bill How can I do this safely without losing all my collab history please ?

 

I also have this problem and deleting Library didn't help.

While investigating, I found that manually loading all the dependencies in the right order makes the issue go away so I suspect it's a bug in dependency tracking or caching.

I'll keep digging!

 

This looks like a bug in Asset Bundle loading/dependency resolution. I narrowed it down to a fairly simple test case (see the attached project):

- Cube and Sphere are super simple addressable prefabs with 'DestroyAfterTime' script that destroys the object after configurable amount of time (set to 5s).
- Root is an addressable prefab that just hold a list of prefabs, configured to reference Cube and Sphere.
- TestScene loads the Root prefab (specified by an AssetReference on the LoadRoot object) and instantiates all prefabs in its list.

The addressable group's bundle mode is 'Pack Separately' so each prefab ends up in its own asset bundle (with Root depending on Cube and Sphere).

Running in editor with Packed Play Mode works as expected but warns about a missing script:



Standalone development build has "The file 'none' is corrupted!" errors and the Cube prefab fails to deserialize correctly (the DelayInSeconds value on its DestroyAfterTime component is 0, making it self destruct immediately):



I was able to recreate this bug without Addressables, just by using the Asset Bundle API to request all 4 asset bundles (Root, Cube, Sphere and default shaders), yield until they're loaded - then async load the Root asset. According to the Asset Bundle docs, this should work as we're not loading the Root prefab until after all dependent asset bundles are loaded.

This is a complete showstopper for us as we have fairly complex dependency graph and only need to load a small subset of all assets at any one time.

Would it help to file a bug for this?

 

This very cool that you can reproduce it, I hope Unity team (@unity_bill) will take a look at this sample!
It it very hard to work since I'm not able to build my game
Thanks a lot!

 

Thanks for the clean repro... we'll look into it

 

Alright, we've gotten to the problem, and are working on a fix. Unfortunately the fix will most likely require an engine change so it'll be a little slower to get out. Let me explain the problem, and then how it could potentially be worked around.

We have 4 assets, A, B, C, and D. A depends on B and C. B and C each depend on D (through engine direct references). A is put in bundleA, B in bundleB, and C in bundleC. D is not explicitly put into any bundle. During the build, D will be duplicated, and pulled into both bundleB and bundleC.

At this point, loading B or C will work fine. What won't work is loading A because of the way A has worked out it's dependencies (it sees 2 D's, and gets confused by them being the same but not the same).

Workarounds:
1. bundle a/b/c together.
2. don't have one addressable contain a direct reference to another one. For example, if A had references to B & C using addressable's AssetReference, it'd be fine. Or if B & C weren't addressable, it'd be fine.

hope that helps. we're working on a real fix so you won't have to workaround.

Hi @unity_bill

Does it means we need to confirm the asset D will only have one reference?
If using the analyze feature could avoid this issue?
Do I can run analyze via script because I am trying to auto run analyze,update or build bundle.
I have found the update function in ContentUpdateScript.
But the analyze function is more complicate to use.
How to call analyze method via script easier?

Thanks.

 

yes, the analyze functionality should be able to pull D out into it's own bundle. Which makes me realize there are 3 workarounds...
Workarounds:
1. bundle a/b/c together.
2. don't have one addressable contain a direct reference to another one. For example, if A had references to B & C using addressable's AssetReference, it'd be fine. Or if B & C weren't addressable, it'd be fine.
3. put D explicitly in it's own bundle.

Running analyze from script is something we are working on improving, but it should be functional at a basic level now.

 

Also, of note, from what we can tell, the system always fixes itself. So it throws the warnings, then properly loads the copies of D. So the workaround mainly gets the annoying message out of the way. If anyone has a repro where things stay broken, we'd love to see it.

 

Hi @unity_bill

I suffer this problems this days on Unity 2018.4.3. In My Project, D is a SubClass of MonoBehaviour. I got the "The referenced script (Unknown) on this Behaviour is missing!" when Load A Prefab. Which A direct refers B and C, and B/C has the same monobehaviour subClass type.

This is the Inspectors of A/B/C.
D is Some_behaviour_1(Script)


I has tryed the 3 workarounds...
1. Bundle together work fine. But Its not Good for my Project as large memory usage.
2. My team designers like direct reference, because they used to edit scene/prefab in Edit Mode.
3. Cant Put D in its own bundle which D is a script.

I Hope the engine fix comes soon. Sorry for poor english.
Thanks.

 

A note on this point. Since A has direct references to B & C, then when you load A into memory, it auto-loads B & C. so I don't think you're saving any memory putting them in the separate bundles.

also I wouldn't think your current setup addresses bullet 2 (your designers liking direct references), because opening A in the prefab editor shouldn't have B & C actually in their for editing. Right? They are just direct references of the script on A.

So it feels like using an AssetReference here would be a good approach. maybe.

 

Hi @unity_bill any chance of you guys including the guid of the missing script, so we can at least verify that it's being bundled correctly?

 

I've confirmed this is fixed in 2019.3.0a12. It will be backported to 19.2 and 18.4, but I do not know when.

 

It’s missed .2.1. It would be great to get some assurances that it’s gonna make .2.2, as it’s a blocking issue. In our case it locks us out of both any addressables version released this year and the 19.x cycle. With some LWRP fixes requiring 19.x this is becoming a bit of a problem.

 

The fix has landed in 2019.2.3f1. The issues fixed are not referenced in the changelog but the fix is there. Test your projects, people!

 

Hi all.
That's fixed in version 1.11.2.
I checked with unity 2018.4.19.
Maybe Next Project I decide to use addressable.
Thanks.

 

We experienced this (or a related) problem in 2020.3.7f1 and were able to fix it using the tip here:
https://forum.unity.com/threads/get...r-is-missing-when-loading-adressable.1157132/

We changed "Monoscript bundle naming" in Addressable Asset Settings from "Disabled" to "Project Name" and that fixes the issues for our project.
