Skeleton Mecanim don't work first time after compile

nicmar

Sometimes when I make a change to code, it recompiles, and I enter play mode, the rig doesn't animate. The animator is moving along like it should, but the spine rig isn't animating.

I need to stop and enter play mode again, then it always works the second time.

Do you have idea why this can happen?

Thanks 🙂

We are sorry for the inconvenience!
What Unity version are you using?
What version of the spine-unity runtime (name of the unitypackage)?

nicmar

It's not that bad, but thanks for looking into it.

Unity 2020.1.4f1
spine-unity-3.8-2020-08-05

Thanks for posting the info.

There have been some bugfixes to Unity 2020.1 that were addressing the import and loading pipeline which solved a related issue (I think it was the Unity 2020.1.5 update which fixed it). Could you perhaps try if a Unity update resolves your problem as well?

Same issue in 2020.1.9 when trying to cache the reference in Start(), just the first time after compilation. I even tried using a coroutine to wait for .AnimationState to != null ... it never gets initialized. Seems I can fix this with:

if(skeletonAnimation.AnimationState == null || skeletonAnimation.Skeleton == null)
{
    skeletonAnimation.Initialize(false);
}

Would be good if this wasn't needed though!

Thanks very much for sharing @Aurigan!
We've just commited a bugfix, new 3.8 Unitypackages are available for download here as usual:
