Crash Unity runtime

nic

Hi
We have made around 15 spine animations and integration in unity without issue but the latest that we made cause an error in unity when doing "ingest":

NullReferenceException: Object reference not set to an instance of an object
SpineEditorUtilities.SpawnAnimatedSkeleton (.SkeletonDataAsset skeletonDataAsset, System.String skinName) (at Assets/Extensions/spine-unity/Editor/SpineEditorUtilities.cs:391)
SkeletonDataAssetInspector.CreatePreviewInstances () (at Assets/Extensions/spine-unity/Editor/SkeletonDataAssetInspector.cs:283)

SpineEditorUtilities:IngestSpineProjectFromSelection() (at Assets/Extensions/spine-unity/Editor/SpineEditorUtilities.cs:160)

The skeleton_data is created but its impossible to spawn it:

I've sent Mitch a message about this thread, he probably look into it when he sees it.

Region not found in atlas: skirt_02 (mesh attachment: skirt_02)

You 100% sure the atlas has skirt_02 in it? If yes, send me JSON and atlas.txt please.

How can I send you the files?

Skype or Email. I PM'd you both.

skirt
  rotate: false
  xy: 151, 152
  size: 111, 102
  orig: 111, 102
  offset: 0, 0
  index: -1
skirt
  rotate: false
  xy: 589, 183
  size: 90, 71
  orig: 90, 71
  offset: 0, 0
  index: 2

This is inside your atlas, skirt_02 is not present, but 2 copies of skirt are .... I don't understand how the atlas generator could have done that... the quick fix is to rename one of those entries (in the front.atlas.txt file) to be skirt_02. You should be able to figure out which one is right pretty quick by the size. Can you email me your spine project as well so I can attempt to generate the error with repro steps for Nate?

Spine's (libGDX) texture packer interprets underscores as images belonging to sequences. Notice how the index is different.
This is eventually useful for Spine when it gets animated attachments (RegionSequenceAttachment) but it does nothing right now (except maybe confuse users who like to use underscores in naming images).

(edit🙂 You can disable this by unchecking "Use Indexes" in the Texture Packer settings in the editor when you're exporting the atlas.

@Shiu, Nate: Maybe a warning could be added in the Editor when packing when the user is using underscores? (and for whitespace stripping and meshes?)

Thanks!

Nate

nic, make sure you uncheck "Use indexes" in the texture packer settings. It should be unchecked by default.

Pharan, yes a mesh warning with stripping would be nice. Someday! Freaking awesome avatar, BTW!
