tk2d (lastest version 4.3)

Just to be sure I understood that correctly - are you using the last released TK2D-package for Unity 4.3, together with an up to date Spine 3.7 runtime in Unity 4.3?

Actually the oposite is true - you will have a hard time using Unity 4.3. I asked because you mention this in your topic name: spine(3.7) + tk2d (lastest version 4.3)

Anyway, you are absolutely right, I can reproduce your problem - it lies within the assembly definition files Spine/Runtime/spine-unity.asmdef and Spine/Editor/spine-unity-editor.asmdef which prevent the required build dependency to TK2D.

I have fixed the bug by automatically renaming (deactivating) the asmdef files, you can download the latest unitypackage with the bugfix here:

Hello,

I'm actually getting the same 3 tk2d errors as kyssmart mentions above, even using the latest runtime posted today (spine-unity-3_7-2019-02-15). I'm on Unity 2018.3.0f2 and the latest tk2d version off the asset store. I also don't even see the Spine tab in Preferences, I assume because compiler errors are interfering with the editor fully loading.

I was following the upgrade instructions for going from 3.6 to 3.7 here Spine-Unity 3.6 to 3.7 Upgrade Guide.

Thanks!
Chris

I tried the entire process again just to make sure I'm not crazy, and unfortunately still getting the same 3 tk2d related errors For due diligence I'll post them again:

Assets\Spine\Runtime\spine-unity\Asset Types\SkeletonDataAsset.cs(46,10): error CS0246: The type or namespace name 'tk2dSpriteCollectionData' could not be found (are you missing a using directive or an assembly reference?)

Assets\Spine\Runtime\spine-unity\Modules\TK2D\SpriteCollectionAttachmentLoader.cs(47,44): error CS0246: The type or namespace name 'tk2dSpriteCollectionData' could not be found (are you missing a using directive or an assembly reference?)

Assets\Spine\Runtime\spine-unity\Modules\TK2D\SpriteCollectionAttachmentLoader.cs(39,11): error CS0246: The type or namespace name 'tk2dSpriteCollectionData' could not be found (are you missing a using directive or an assembly reference?)

Still using the latest runtime package here Spine Unity Download (3_7-2019-02-15).

Help would be super duper great! Our animator can no longer use 3.6 apparently (he says it's forcing him to update to 3.7), but on my end I can't upgrade due to these errors, so our animation pipeline is at a bit of a standstill. Thanks!

Just a side note: Spine doesn't force you to upgrade to 3.7. You can set the editor version in the Spine settings:

Settings - Spine User Guide: Version

If the Spine Preferences menu section does not show up, then my latest modifications unfortunately will not help much - it only renames the two .asmdef files to .txt to disable them when clicking the Define TK2D - Enable/Disable buttons.

As the easiest solution, please simply rename the files manually, then everything will work:

• Spine/Runtime/spine-unity.asmdef to Spine/Runtime/spine-unity.txt and
• Spine/Editor/spine-unity-editor.asmdef to Spine/Editor/spine-unity-editor.txt
  same with the meta files:
• Spine/Runtime/spine-unity.asmdef.meta to Spine/Runtime/spine-unity.txt.meta and
• Spine/Editor/spine-unity-editor.asmdef.meta to Spine/Editor/spine-unity-editor.txt.meta

Yay that worked! I've been wanting to try something like that but couldn't tell from your post above what they needed to be renamed to. Until your most recent post of course! Thanks a ton!

And yea @badlogic that didn't sit well with me either, him saying that.... but we needed to update to 3.7 eventually anyways, and had been putting it off, so it was kind of just a good excuse haha.

Thanks again everyone!

Great to hear, thanks for getting back to us!

I'm getting this issue now. I would really like a fix for this soon because these errors are seriously stalling the progress of my project.
What happened:

I went to preferences -> Spine -> and clicked enable for TK2D settings. This was by accident as I thought it was a "save" button for the other settings there, I did this instinctively since other UIs have something similar. Unfortunately, Unity crashed and when I restarted I had the same 3 errors. I tried your fix by changing to .txt inside of Unity but it didn't work for me, ie: Spine/Runtime/spine-unity.txt and Spine/Editor/spine-unity-editor.txt as well as the meta files.

Any help of this issue is really appreciated because I need a fix for this urgently! Thank you..

I deleted my old Spine-unity import which was probably 3.8 since I installed it Septermber 2019 and re-installed 3.8 into Unity, yet the Spine tab is still invisble in preferences. Unity version I'm using: 2019.2.0f1

UPDATE:
I fixed it by going into each file and commenting out whatever I needed(2 files where the errors were) to until the errors went away in Unity. After the errors were gone I disabled TK2D and uncommented them again in the files. That fixed my issue but please have a fix for this for others in the future, thank you.

We are very sorry for the troubles!

We have just committed a fix where the TK2D Spine preferences menu entry is not showing up when 2D Toolkit is not installed in the project. This shall prevent any accidental clicks in the first place.

You can download the latest unitypackage here as usual:
