Sprite Collections Not Working

[m3taphysics]

Hi, Im getting lots and lots of errors when trying to setup sprite collections.

Firstly there is very little details on how to setup a SpriteCollection. I eventually figured out its a component which has a button to open the SpriteCollection editor (its no where in the documentation). Although it does have details on how to setup sprites once you get to this.

If I open up the spider collection, that works fine and I get no errors.  If I try to create my own like so:

Create a GameObject -> Attach a SpriteCollection to it -> Drag onto prefab -> Hit "open editor", I get the following errors:

Code: [Select]

I can work on other things until this is resolved but its slowing down production, we are on a tight deadline!

Thanks.

You should not attach sprite collection to any object. Instead, do the following in the Project panel: Create -> tk2d -> Sprite Collection.

Once you commit the collection, start creating sprites in the Hierarchy panel: Create -> tk2d -> Sprite.

I'm not sure which docs you're referring to, but this tutorial is pretty much a step by step on how to setup a sprite collection:
