Spine animation not playing in Unity dopesheet

rXp

Hello,

I generated a unity animation controller from a spine animation. When played in game it works perfectly.
The issue is that I need to do a bit of more work on the animation in unity : I need to add some colliderboxes to the animation (for each frame).
When I am in the unity animation window and I try to play the animation while in the dopesheet, the animation does not play. I can set the colliderbox and it moves like I want but the animation itself does not.

Is that normal ? What can I do ?

Are you using Mechanim for this?

Yes (right click, spine, instantiate (mechanism))

This is normal.
SkeletonAnimator's system is a workaround to allow users to use Mecanim with Spine. The clip assets that SkeletonAnimator creates are dummy animations that determine the duration (and hold the Unity Animation Events). But not the actual animation data. This is because the Unity animation clip format does not support the full range of Spine features. So Spine animations could never be converted into actual Unity animation clips. That's why they can't be previewed using the animation view.

Do you only want to pose the skeleton so you can define the collider shapes? We can make a simple editor tool that can do that.

Yes that is what I need to do.
We are doing a Fighting games and the different hitbox/hurtbox need to be set frame by frame and will be balanced in the same way.
That tool would greatly help us. The other solution is for us to make spritesheet but with the resolution we are working with, it would just blow up the size.

Something quick and dirty for you to use:
Just add it to your object. Don't forget to remove it when you're not using it. It doesn't do anything outside the Unity editor.

SkeletonPosePreview.cs

using UnityEngine;
using Spine;
using Spine.Unity;

[RequireComponent(typeof(SkeletonRenderer))]
public class SkeletonPosePreview : MonoBehaviour {

   [SpineAnimation] public string animationName;
   [Space]
   [Tooltip("Allow time scrubbing in the inspector according to seconds instead of percentage of the duration.")]
   public bool useSeconds;
   [Range(0, 1)] public float percentTime;
   public float seconds;

   SkeletonRenderer skeletonRenderer;

   public void OnValidate () {
      percentTime = Mathf.Clamp(percentTime, 0, 1);

  if (skeletonRenderer == null) skeletonRenderer = GetComponent<SkeletonRenderer>();
  if (skeletonRenderer == null) return;
  if (!skeletonRenderer.valid) return;
  if (string.IsNullOrEmpty(animationName)) return;

  Skeleton skeleton = skeletonRenderer.skeleton;
  Spine.Animation spineAnimation = skeleton.data.FindAnimation(animationName);
  if (spineAnimation == null) return;

  float duration = spineAnimation.duration;
  if (useSeconds) {
     if (duration == 0) {
        seconds = 0;
        percentTime = 0;
     } else {
        if (seconds < 0) seconds += duration; // Allow backscrubbing.
        seconds = seconds % duration;
        percentTime = seconds / duration;
     }
  } else {
     seconds = percentTime * duration;
  }

  skeleton.SetToSetupPose(); // Spine-Unity 3.4 and below
  spineAnimation.Apply(skeleton, 0, seconds, true, null); // Spine-Unity 3.4 and below
  //spineAnimation.Apply(skeleton, 0, seconds, true, null, 1f, true, false); // Spine-Unity 3.5
   }
}

Thx for that but it is only partially working. The model is animating but not all the bones.
For example "standing light punch" only the wrist is moving, not the arm.
Should I try the spine-unity 3.5 beta ? Because I looked but there is nothing special in the code, you just use all the skeleton.

You shouldn't need to. It works fine in 3.4. That's where I tested it first.
I checked with a bunch of different skeletons too and it seems to function correctly.

Is there a way to send you privately the skeleton ? Maybe the problem is on my side.

You can email it to unity@esotericsoftware.com
You can attach it or send a dropbox link or something.

I sent it there 🙂

Skeleton 'Armailli.json' (exported with Spine 2.1.27) may be incompatible with your runtime version: spine-unity v3.5

You seem to be using a very very old export. If you try playing the animations normally in the latest runtimes 3.4 or 3.5, you'll notice they don't work correctly.

If you are indeed using a Spine 2.x runtime, it should work fine.

I see 🙂 Thanks for the help 😃
