Can't create animation clip

[mr_malee]

Not sure how this happened, but whenever I try to create a new animation clip after creating a new sprite animation I get this error popup:

Invalid Sprite Collection found in clip. Please correct this in the inspector.

then Unity outputs this error:

Code: [Select]

ArgumentOutOfRangeException: Argument is out of range.

The errors don't stop and I have to force quit Unity.
Currently unable to make new animations

I've tried rebuilding index and checking integrity, everything reports ok.

I have 3 sprite collections with 2 platforms (UI, Game, Fonts). They all compile fine, no errors output.

1. Try rebuilding the index (2D Toolkit > Rebuild Index)
2. Find all sprite collections in the project (expand the -tk2d object to see what tk2d knows about). Maybe there is something corrupt in the project? If you do find a corrupt one, delete it and rebuild index

[mr_malee]

Is there anything specific I should be looking for? Everything looks fine in the collection. I've tried rebuilding the index as well.

In order to create new animations I have to duplicate an existing one then modify.

[mr_malee]

ah found it.

it was my Font sprite collection. For some reason having 2x platform fonts seems to break the animation system.
I removed all platforms from my font sprite sheet, recompiled, rebuilt index.

Now I can create new animations

But I've just lost HD fonts

[unikronsoftware]

Lost HD fonts how? Have you tried restarting Unity?

[mr_malee]

what I mean is, if I add a 1x and 2x platform in my Font Sprite Collection (collection which only contains 1 font) and commit. I'm then unable to make animations.

Maybe I don't understand the workflow for 2x fonts.

1. Create a font and png at 1x (font size 16)
2. Create a font and png at 2x (font size 32)
3. Add the 1x font into the sprite collection
4. Put 2x font into a sub folder named "2x", name font.png "font@2x.png", name font.txt "font@2x.txt"

Is there something else I need to do?

I've attached a test project that replicates the problem. Try and create a new animation clip in the "TestAnimation" sprite animation.

You don't seem to have any sprites in your project - you've also deleted the samples folder which would have had a few valid sprites in there. You can't create an animation while you don't have any valid sprites in the project.
