NudityStation - Prefab Variants Cause Missing References And Lose Connection To Parent #2551

chairbender · 2020-01-06T02:29:41Z

Temporary Workaround

There are 2 ways to workaround this in the meantime. DO NOT DO A REIMPORT ALL, SAVE YOURSELF THE TROUBLE.

If your prefabs have stopped adjusting their settings from the parent prefab (this can happen with clothes, they lose their item attributes settings), right click the Prefabs folder and choose "Reimport" (NOT REIMPORT ALL).
If you have assets which have "Missing" for a field that should reference a prefab, git reset --hard should fix it. This restores the missing asset reference. I don't think you need to close Unity.

Both of the situations seem to happen after doing a standalone build. So you might want to check after you do a build to see if clothing items (such as MiningHardsuit.prefab) have correctly filled out ItemAttributes and references aren't broken (such as SmallBoxPopulator's references to breath mask)

Description

This only seems to affect prefab variants and references to prefab variants. It usually shows up in the game where you spawn the player and they are missing several of their starting items.

This usually only happens after merging or switching branches or doing a standalone build.

You can see this in action in 2 ways (sometimes only one of them happens).

Go open an asset which has prefab references, such as SmallBoxPopulator. Note that one of the fields is "Missing".
Go open MiningHardsuit.prefab. Note that ItemAttributes fields are all blank.

The text was updated successfully, but these errors were encountered:

I'm adding those lines to the PopulateItemStorage function:

			// General protection against missing items
			if (Contents[i] == null)
			{
				Logger.LogError($"Item is missing at position {i} of {toPopulate.name}");
				continue; // Will skip the missing item
			}

That won't solve the issue but will make finding the missing asset easier and won't cause a bug when starting the round.

Here's some screenshots / snippets of what it looks like:
Smallbox fails to spawn with breath mask in player inventory. Here's what the inventory populator looks like.

Here's the yml for this asset

  Contents:
  - {fileID: 6404652678407139925, guid: dce8e376d2eca40eabe3f055b41a021c, type: 3}
  - {fileID: 1277678737481138, guid: f99902d04c3b1fe47b0e4e4ec36b7971, type: 3}

Here's the yml for BreathMask.prefab.meta:

fileFormatVersion: 2
guid: dce8e376d2eca40eabe3f055b41a021c
PrefabImporter:
  externalObjects: {}
  userData: 
  assetBundleName: 
  assetBundleVariant:

SEE? The asset ID is correct! The populator is referencing the correct GUID for breathmask. But it's being treated as if it's missing.

JesterX666 · 2020-01-06T02:41:49Z

A mystery to be solved : why did we both get the same issue, at the same time, with the same asset? (Breathmask too!)

chairbender · 2020-01-06T03:10:28Z

also here's the YML for BreathMask.prefab. I'm thinking maybe it's the fileID reference that's wrong? I'm not sure what in here corresponds to fileID, maybe that --- !u!1001 &3573969270142637268 thing? That doesn't match the fileID in SmallBoxPopulator:

so I just fixed this by closing unity, git reset --hard, then switching to develop, then reopening unity. The file contents are still the same but it didn't require a reimport.

chairbender · 2020-01-06T03:27:53Z

And then it broke after I made a standalone build of the game.

chairbender · 2020-01-06T03:31:48Z

So I closed unity, did a git reset --hard, reopened, then when I open the StandardSmallBoxPopulator asset in editor the reference is no longer shown as missing. I checked and saw that the file contents I pasted above were still all the same. Then I created a standalone build. After the build was done, I got the "importing..." progress bar, all of my prefab assets showed as modified by git, and this issue reappeared. It was only the prefabs that were showing as modified. This particular asset, BreathMask.prefab, only differs by line separators according to git.

chairbender · 2020-01-06T03:35:37Z

And the key difference I noticed between the assets that this happens to and the ones it doesn't happen to is, the ones it happens to are prefab variants. The ones it doesn't happen to are just normal prefabs.

chairbender · 2020-01-06T03:40:43Z

Temporary workaround. Building standalone game causes the issue. Git reset hard fixes it. So, after every standalone build you should ensure you've committed your changes and run git reset --hard. This restores the missing asset reference. I don't think you need to close Unity. It doesn't seem like Editor build causes the issue, only standalone.

chairbender · 2020-01-12T00:31:29Z

Updated with new findings and temporary workaround.

Working on a reproduction to submit a bug report.

foma heard from a Unity dev that this is supposedly fixed in 2020, but it's going to be awhile before we actually switch to that

Aranclanos · 2021-03-18T22:57:47Z

the project updated its unity version and nuditystation doesnt seem to be happening anymore, or prefab variants losing the values of their parent
