[libgdx] Skeleton Actors sharing data from Template

Olehandro

Hello!
I am making game demo using libgdx & spine runtime.
I successfully imported my skeleton from spine. I can load skeleton, change attachments, play animations.
When he is alone. It's ok.

Now i want to spawn many libgdx Actors, who have own positions, attachment indexes for weapon/armor slots and animations states (but share one Skeleton as a template). It mostly works. But i have trouble setting animation for each of Actor.

I copy some "update" code:

public void applyAnimationState() {
    animationState.apply(getSkeleton()); // Poses skeleton using current animations. This sets the bones' local SRT.
    animationState.setData(getComponent().animationStateData); // Holds the animation state for a skeleton (current animation, time, etc).
    //animationState.setAnimation(0, STATES[heroAnimState], true);  // <

---

 interrupts animation, so i always see frame 0
}

public void applyAll() {
    applyAnimationState();
    applyFlip();
    applyPosition();
    applyAttachments();

getSkeleton().updateWorldTransform(); // Uses the bones' local SRT to compute their world SRT.
}

public void draw(Camera camera) {
    applyAll();

batch.getProjectionMatrix().set(camera.combined);
//debugRenderer.getShapeRenderer().setProjectionMatrix(camera.combined);
batch.begin();
//setup skeleton template to view locals
renderer.draw(batch, getSkeleton()); // Draw the skeleton images.
batch.end();
}

My problem is in:
animationState.setAnimation (setting it will reset animation to start)
not setting it i have all Actors playing one animation.

I share one animationState for all Actors. Is it wrong?

So, if i call
animationState.setAnimation in each Actor.draw

for (SkeletonActorComponent actor: actors    ) {         actor.draw(camera);      }

they all have frame 0

how can i apply frame/timeline for each?

Okay, looking through utils sources https://github.com/EsotericSoftware/spine-runtimes/tree/4.0/spine-libgdx/spine-libgdx/src/com/esotericsoftware/spine/utils
i see in SkeletonActoorPool class, that each Skeleton have animationState pair. So will do i. I will share Template's atlas & data to prevent loading duplicates. Thx 🙂

Sounds like you figured it out, but AnimationState stores the animation state for one skeleton. Each skeleton you want to animate independently will need its own AnimationState instance.
