Hiya,
First of I would like to congratulate you on a fantastic product.
I have an issue with Asset Bundles and tk2d where I get the following error
Inconsistent asset when sorting preload assets: '' fileID: 0
My asset bundle is extremely simple. I have one prefab which consist of
- prefab (empty gameobject)
-> sprite (tk2dSprite)
When I try and build a bundle (with dependencies) from this prefab (using the script from here http://docs.unity3d.com/Manual/abfaq.html), it throws the above error.
I tested building a bundle from just a tk2dSpriteCollectionData, and that works fine.
I tested building a bundle with just empty gameobjects, and that works fine.
But with a tk2dSprite attached to a gameobject it doesn't work.
Is this not possible?
Thanks in advance for any help given.

Is that an error or a warning? I've not seen it before, but from what google says, its just a warning and not an error and that the assetbundle does get built correctly... If not, can you post a repro case of this, I'll be happy to take a look and see how this can be fixed. Prefab asset bundles work on my main project, but the setup could be different on yours.

Thanks for the quick reply.
It's definitely an error, or at least that's what it's coming up as in the editor.
If I create a bundle with a single prefab with the above mentioned content, I get the error and the file size for the bundle is about 5.5 MB.
If I create a bundle with only the SpriteCollectionData object from the sprite in the prefab I don't get the error and file size for the bundle is about 10.5 MB.
So unfortunately I don't think it is creating the bundle correctly.
The only special thing I'm doing is that I've disabled "//if (!i.managedSpriteCollection)" in "BuildLookupIndex" for "tk2dSpriteGuiUtility", to be able to choose 1x and 2x SpriteCollections in the editor. So I can build seperate bundles for 1x and 2x.
I've attached a zip file of the actual prefab, but I don't know if that is enough? Do you want a whole project setup?

Are you using platform collections? That isn't going to work as it uses Resources.Load for the sprite collection data there...
Also I'll need a bit more than just the prefab, ideally a scenario / project where I can build the asset bundle in a way that it breaks. If you write a bit of code to load the asset bundle, and then print out all the objects in it, you might find out what is missing.
-
Yes, I'm using platform collections. I have however made a system where I followed instructions from this forum entry http://2dtoolkit.com/forum/index.php?topic=1522.0
Would the scenario mentioned in this forum entry not work? If I build seperate bundles with 1x and 2x textures, and load them... would it not set the correct sprites using this approach? I am still at making bundles stage, so haven't loaded any of them in yet.
However waking up Monday morning with a fresh restart on my machine, I don't get the error anymore?? So it seems fixed(?), or that is at least the dream.
I will report back with more information if it start occuring again.
-
Next time it happens, try restarting into an empty scene, see if that fixes it. I think its something to do with the temporary link that exists when the object is being used, its a link to a transient object which may be what is throwing it off.
-
Thanks for that, I'll keep that in mind next time it happens.
Would my approach to platform bundles work, or should I find another way to do it?
-
I think it will work, but I can't say for certain as I haven't tested it. You do have the source code though... :)

Cheers, I'll give it a crack... just don't like modifying external libraries too much in case I need to update it for some reason (creates a general havoc).
Thanks for quick and helpful replies!
