Never ending "Rebuilding Index"

[rxmarcus]

I've searched the forums and seen many people in the past have the issue of "Rebuilding Index" appear and cycle for infinity, but haven't found a solution for myself. 
For the first time in my project I'm trying to create an sprite animation using a sprite sheet. 

When I create a new SpriteAnimation, Open Editor, and choose "Create -> New clip", the Rebuilding Index message appears and continues forever.  Unity displays the error "Unable to find sprite collection. This is a serious problem."  I just updated 2DToolkit to the latest version today, but it did not help.  Also I do use SVN, if that makes a difference. 

Any help would be appreciated.

What happened to cause it? Did you copy your project using dropbox, what does the 2D Toolkit integrity checker say when you run it?

[rxmarcus]

To be honest this is the first Sprite animation I've attempted to create in my project, so I haven't seen the issue until just now.  Doing normal static sprites with sprite collections is working fine.  I ran the integrity checker and it says its fine.

Try rebuilding the index, and see if that helps? Otherwise expand the -tk2d / sprite collection index object, and see if there are any weird / empty looking ones in there. It looks like something is corrupted in the project.

None of those ideas helped unfortunately.  However I opened up the ~2dtk collection as you mentioned, and there are lots of items in the list just called "Element 46", "Element 52" etc. Which do not have a name when you click on them, and appear empty.

Perhaps these are corrupt as you mentioned.  If thats the case, do you know how I can clean those up?

I just deleted the ~2dtk collection file, and then did a "Rebuild Index". It came back but has all those strange elements again....

Here is an image of what I'm seeing in regards to those elements that seems corrupted:


thanks

It looks like there are a few corrupt sprite collection data objects in your project. We'll need to find those... The easiest way to do that is to create a new editor script to select them, something like this:

Code: [Select]

[MenuItem("Temp/SelectBrokenStuff", false, 10098)]
public static void LaunchDocumentation()
{
Selection.activeGameObject = Resources.LoadAssetAtPath(AssetDatabase.GUIDToAssetPath("b93a0e9780302e64bbb90ff6fd198f12"), typeof(GameObject));
}
Running that should select the first broken thing (Element 21), check what it is and delete if necessary. Repeat for the rest of the broken ones.

hmm, im not very familiar with editor scripts, would I be doing what is found here? :  http://docs.unity3d.com/Manual/editor-EditorWindows.html

Or maybe a simple explination of what I need to do. Create a new script, and put that code in it?

[unikronsoftware]

Create a new script in a folder called Editor. Replace the contents with this.

Code: [Select]

using UnityEngine;
using UnityEditor;
using System.Collections;

public class SomeEditorStuffZ19283 {

[MenuItem("Temp/SelectBrokenStuff", false, 10098)]
public static void LaunchDocumentation()
{
string guid = "b93a0e9780302e64bbb90ff6fd198f12";
Selection.activeGameObject = Resources.LoadAssetAtPath(AssetDatabase.GUIDToAssetPath(guid), typeof(GameObject)) as GameObject;
}
}

Replace guid with the guid of the thing you want to select, i.e. one of the broken ones.

Ugh..... cleaned up all of those sprite collections, still having the same problem.  Time to just use Unity's new 2D stuff in 4.3 I suppose.

[unikronsoftware]

Hmm... if your project is small enough send me a repro at support at unikronsoftware.com. There must be something left over somewhere...

[rxmarcus]

Its pretty darn large at this point unfortunately.  I don't see any more of those "Element" ones in my ~2dtk file, and i also did a fresh reinstall of 2dtoolkit and rebuilt the index.  Really strange because the issue only appears when I attempt to create a "Clip" inside a sprite animation object.

[unikronsoftware]

Take a look at the other sprite collections, maybe there will be a hint - if theres anything else with version = 0, or 0 sprites in it. Also post a screenshot of the first item in the list.

[rxmarcus]

Turns out there was 1 remaining collection that had a crazy set of characters and numbers, similar to a GUI for its name.  I found and deleted this object, rebuilt the index and now its working!!!

thank you for your support on this, hopefully this will help others as well.
