The bone hierarchy is just for transformations. Unity Scene graph specifies the draw order. Change the cannon position in the scene hierarchy.

Ok, let me see if I understand you correctly.

All 3 cannons = 1 animation? In which case you're trying to interleave two animations?

You want to draw two of the cannons/slots in the BG, draw the character, and then draw the last slot/cannon in front?

I thought you were looking at 3 instances of Cannon and a single instance of the character, but this is not correct. Truth?

Simple Options:

1. Add empty slots for weapons to character animation. Animate weapons slots according to weapon class {blaster, rifle, cannon, etc...}. Add Attachments to slots only when weapon equipped. See Goblins Demo.

2. Split the Canons animation in Half [Editor], render : Canon_1_2, Character, Canon_2_2

3. Duplicate the Cannon animation, clear the slot attachment(s)

   , render: Canon_No_Front, Character, Canon_No_Back[/*][/list]
   #1 is how Spine is designed to work.

   [*]Use [url=https://github.com/EsotericSoftware/spine-runtimes/blob/master/spine-unity/Assets/spine-unity/SkeletonRenderer.cs#L215]zSpacing[/url] on Meshes, add 'zOffset' and pray that MeshRenderer sorts submeshes by zOrder in the transparent layer.[/*]
   [*]Complete SkeletonRenderer rewrite[/*][/list]

Sadly this isn't a trivial problem heh; I've been thinking of a few ways to solve it involving submesh renderers and using the DrawOrder of a given slot to influence Unity's "Order in Layer" property for z sorting. Its ugly and complicated though.

Here's a video of how a little bit of that works.

This functionality is all in the runtimes if you want to leverage it. Take specific note of how asterisks * are used to generate new mesh renderer passes.

Why don't you create a single skeleton with the weapon and then at runtime draw that skeleton three times ? You could use empty bones/slots as indicators of where you want the weapons to appear.

I will reply to this in a few hours but it won't be a pretty solution.

(See example scene and spine source files)

Here is how I would accomplish this. Take specific note of how the Events are used to push specific slots forward/backward in the sorting order.

public class SubmeshOrderInLayer : MonoBehaviour {

   SkeletonAnimation skeletonAnimation;
   SkeletonUtilitySubmeshRenderer[] renderers;
   

   void Start () {
      skeletonAnimation = GetComponent<SkeletonAnimation> ();
      skeletonAnimation.state.Event += HandleEvent;
      renderers = GetComponentsInChildren<SkeletonUtilitySubmeshRenderer> ();
   }

   void HandleEvent (Spine.AnimationState state, int trackIndex, Spine.Event e)
   {
      if (e.Data.Name == "OrderInLayer") {
         int index = skeletonAnimation.skeleton.FindSlotIndex(e.String);
         renderers[index].sortingOrder = e.Int;
      }
   }

}

I know it sucks but its what i've got for your unique situation at the moment. Goodluck! :S

I've only seen the submesh '*' trick rendering in Unity. I checked the other renderers and could not find it. It's dependant on how a renderer works, Unity uses a scene graph which does a lot of sorting and render state optimizations. A lot of other renderers issue render commands immediately.

Heh yea; his screenshots had Unity stuff in it so I was addressing it in terms of Unity Sorry for confusion.

You got my hopes up is all, thought I'd missed a secret feature.

Nice hack, btw. 8)

Thank you for your help . It can solve part of the problem . Just like the canon . :clap: Is this the temporary solution or the final solution ?

And the others are not solved :

1.Not all of Weapons like the canon . For example , the AK-47 , I want it in front of the character body and behind the right arm . So , it is impossible to create a single skeleton with the right arm . Even the whip weapon , I want it behind the character in some frames and in front of the character in other frames .

Is this can be solved in the future ?

This can be solved with the same solution. rename "RightArm" slot to "*RightArm" then set its Sorting Order to something higher than the Whip's Sorting Order in Unity.
