Go to setup pose not working?

raeiraei

Hello,

I'm using a character with 3 view skeletons: south, sideways and north.

Problem:
When playing death animation the character is stuck in animation. The method I've tried to reset skeleton:
1) make sure that skeleton animation + parent objects are active
2) set slots to setup pose
3) set bones to setup pose
4) set all tracks to empty animation
5) set new idle animation
6) use skeletonanimation.state.update(0f)

This results in the character view that died still being stuck in death animation, and on next view reactivation mixes from death to whatever animation is played next.

Help?

Harald

raeiraei This results in the character view that died still being stuck in death animation, and on next view reactivation mixes from death to whatever animation is played next.

Could you please describe what do you mean by "on next view"? Do you mean in the following frame, or when you change from front to the sideways view? Please be sure that you are issuing the respective calls at every one of your three separate SkeletonAnimation objects.

Please also note that in case you're still open to changing your 3-direction workflow, you might want to consider alternative ways to include the three directions in a single skeleton, as mentioned in this forum thread recently:

By next view I mean when changing from front to sideways. Indeed all calls are made to all skeleton animations.

Unfortunately we are relatively deep into developing the spine character, and the different skeletons are not exactly identical in bone structure, name convention and animation method. Switching to the more elegant skin view solution you posted might be too much of a headache at this point. Too bad we didn't discover the method before we dove in.

I've solved the problem by now. Instead of using the above methods to reset the skeleton animation right before screen fade in on reload, I'm activating skeleton views after death fadeout and leaving the objects active for a while, then hiding the relevant views before fade in. This workaround of simply leaving the game objects active for longer after making the calls makes no sense at all to me, and my confusion is above lv9000 😃

@raeiraei If you are issuing the mentioned calls at all skeleton objects, I assume that you had two of the three skeleton GameObjects disabled completely. Then you might be missing the respective Update() and LateUpdate() calls which would apply the animation to your skeleton, and then update the mesh according to your updated skeleton state. While you mentioned that you've tried to call some methods to reset the skeleton, from the description above it's not completely clear which calls you have combined in which order. What was definitely missing in your initial list is updating the mesh to the skeleton state, which is done by the LateUpdate() call.

In general it would be prefered if you could share code that you used instead of describing what you did in prose, as such a description automatically becomes more vague.

These are the methods I'm using to reset skeleton animations:

visibleSkeletonHandler.DebugSetAllSkeletonsVisibility (true); SetSkeletonAnimationsSlotsToSetupPose (); SetSkeletonAnimationsBonesToSetupPose (); SetAllSkeletonsAnimationTracksToEmptyAnimation (); SetAllSkeletonsStateTimeToInputUpdateTime (0f); SetMovementAnimationState (MovementState.Idle);

Each of these methods are calling all skeleton animations after the skeleton game objects have been set active and are active in hierarchy.

The spine methods called on all skeletons behind these methods are, in the order of the methods above:

skeletonAnimation.Skeleton.SetSlotsToSetupPose

skeletonAnimation.Skeleton.SetBonesToSetupPose

  for ( int i = 0; i < trackAmount; i++ ) {
        skeletonAnimation.state.SetEmptyAnimation (i, mixTime);
    }

skeletonAnimation.state.Update (time);

Where track amount is 10 and mix time here is 0f, skeletonAnimation.state.Update is also 0f.

The movement state method results in skeletonAnimation.state.SetAnimation("idle",loop = true, mixDuration ,2f) call for all skeleton animations.

Harald

raeiraei Thanks for the additional info. Depending on whether you want to immediately clear any animations (without mixing out), you could call the following to immediately clear any animations and update the skeleton and mesh before the next frame is rendered:

skeletonAnimation.AnimationState.ClearTracks();
skeletonAnimation.Skeleton.SetToSetupPose();
skeletonAnimation.Update(0);
skeletonAnimation.LateUpdate();

Hey Harald,

I assume you are refering to the skeletonAnimation.state.ClearTracks() 🙂 Either way, your approach works in a clean test project on disabled game objects, so I must be effing something up somewhere else in the main project.

Thank you very much for your patience and help.

Throwing some search breadcrumb words in here for people to google:
unity, runtime, spine cant reset skeleton, spine cant reset character, spine stop animation, spine cant stop animation, spine go back to setup pose, spine how to reset animation

Harald

raeiraei I assume you are refering to the skeletonAnimation.state.ClearTracks() 🙂

Ah yes, sorry and thanks for the hint! 🙂 I've corrected it in the original posting so it does not confuse others.

raeiraei For those who cant get .update(0) to work, make sure you are calling the update on the skeleton animation, and not on the state of the skeleton animation.

Yes, updating AnimationState only would be missing the call to apply the state to the skeleton, and to re-generate the mesh according to the skeleton.
