Unable to create animation clips

[gdeglin]

Somehow I broke things in such a way that I am no longer able to create new animation clips even though I can create sprites just fine.  I get the following errors when I create a clip...

"Unable to find any sprite collections (from the GetDefaultSpriteCollection method)" followed by ...
NullReferenceException: Object reference not set to an instance of an object
tk2dSpriteAnimationEditorPopup.CreateNewClip () (at Assets/TK2DROOT/tk2d/Editor/Sprites/SpriteAnimationEditor/tk2dSpriteAnimationEditorPopup.cs:357)
tk2dSpriteAnimationEditorPopup.<DrawToolbar>m__33 (System.Object userData, System.String[] options, Int32 selected) (at Assets/TK2DROOT/tk2d/Editor/Sprites/SpriteAnimationEditor/tk2dSpriteAnimationEditorPopup.cs:395)

I tried removing all 2d toolkit plugin files and re-installing from the asset store but this seems to break lots of stuff. Specifically, I get multiple define errors between my TK2DROOT/tk2d/Code/* directories and my Plugins/tk2d/* directores.

If I copy the the TK2DROOT/tk2d/Code/* directores into the Plugins/tk2d folder (as the Setup For Javascript command normally does), most of the errors go away. But I still get an error that says "The type or namespace name `tk2dClippedSpriteSample' could not be found." ... which is weird because I thought this was renamed to just tk2dClippedSprite instead of tk2dClippedSpriteSample in 1.92. And in either case, my clip creation problem is not solved.

The problem just got even stranger (but hopefully closer to a solution...)

If I remove multiple platform support, I am able to create a clip just fine. But once I add 1x, 2x, and 4x I get the same error as above.

Ok I found a solution. Creating a throw-away sprite collection that has no multiple platforms enabled seems to make things work.

I take it you've not imported or deleted the demo sprite collections?
I thought I resolved this a while back, but perhaps not... what version of Unity & 2D Toolkit are you using?

[gdeglin]

Yeah I excluded the demo files. Version 1.92 final. Unity 4.1.2f1

[unikronsoftware]

I've added that to the TODO for 2D Toolkit 2.0

Update - this has been fixed in 2.0.
