update mesh after change of bones

Seryoga

I have some code

void Start() { 
Bone[] bones = active_state.GetComponent<SkeletonAnimation>().skeleton.bones.Items;
                  for (int i = 0; i < _j.Count; i++)
                  {
                      for (int j = 0; j < bones.Length; j++)
                      {
                          if (bones[j].data.name == _j[i]["n"].str)
                          {
                              bones[j].rotation = _j[i]["r"].n;
                              bones[j].x = _j[i]["x"].n;
                              bones[j].y = _j[i]["y"].n;
                          }
                      }
                  }
                  }

How I can update mesh after change of bones?

Loading Image It's after change of bones
Loading Image It's after after an animation call
Position of bones is identical.

After modifying bones, you can call skeletonAnimation.skeleton.UpdateWorldTransform()

But if you are using a SkeletonAnimation, it's cleaner and more reliable to subscribe to the events.

void Start () {
     mySkeletonAnimation.UpdateLocal += delegate {
          // move bones here.
     };
}

The UpdateLocal handler can also be a named method.

Thanks, but it doesn't work.I have created the button and I use this code :

void OnMouseUpAsButton()
   {
       GameObject pers = GameObject.FindGameObjectWithTag("player");
       SkeletonAnimation myanim = pers.transform.GetChild(0).GetComponent<SkeletonAnimation>();
       Bone[] bones = myanim.skeleton.bones.Items;
       JSONObject _j;
          myanim.UpdateLocal += delegate {
           _j=new JSONObject(PlayerPrefs.GetString("mesh"));
               for(int i=0;i<_j.Count;i++)
                   for(int j=0;j<bones.Length;j++)
                       if(bones[j].data.name==_j[i]["n"].str)
                       {
                           bones[j].rotation = _j[i]["r"].n;
                           bones[j].x = _j[i]["x"].n;
                           bones[j].y = _j[i]["y"].n;
                       }
           };
        }
       }

That is bones change a position and the mesh - doesn't do it. I need to change position of bones once for example by clicking. After that Meshattachment have to change. The Meshattachment of a skirt hasn't changed. I also tried UpdateWorldTransform and it has also not helped

You said it was working.

If your animation is also controlling the bone, it can override the bone position depending on script execultion order, which is nondeterministic unless you set it. If you'd rather not set it, you will need use UpdateLocal (or UpdateWorld).

Weighted meshes will render correctly as long as the bone is positioned correctly before the render call (LateUpdate).

I have hurried then. Maybe you speak about updating of this mesh? - http://esotericsoftware.com/spine-weights?lang=en but I speak about this mesh - en.esotericsoftware.com/spine-meshes. For the test I don't use any animations before and after installation of bones
