Move Humanoid Muscles

I am messing around with unity's HumanPose and HumanPoseHandler, and I am having issues.

I have a script that contains 2 fields "root" and "amount" and nothing else. I then created this Editor class:

Code (CSharp):

1. using UnityEditor;
2. using UnityEngine;
3.  
4. [CustomEditor(typeof(Pose))]
5. public class PoseEditor : Editor {
6.  
7.     HumanPoseHandler hph;
8.     HumanPose hp;
9.     Avatar avatar;
10.     float[] defaultMuscles;
11.  
12.     Pose t;
13.  
14.     public void OnEnable(){
15.         t = target as Pose;
16.         avatar = t.GetComponent<Animator>().avatar;
17.         hph    = new HumanPoseHandler(avatar, t.root);
18.         hp     = new HumanPose();
19.         hph.GetHumanPose(ref hp);
20.         defaultMuscles = hp.muscles;
21.     }
22.  
23.     public override void OnInspectorGUI(){
24.  
25.  
26.         t.root = EditorGUILayout.ObjectField(new GUIContent("Root", "Usually the characters hips"), t.root, typeof(Transform), true) as Transform;
27.         t.amount = EditorGUILayout.Slider("Amount", t.amount, -180f, 180f);
28.  
29.         for (var i = 0; i < defaultMuscles.Length; i++) {
30.             hp.muscles[i] = Mathf.Clamp(t.amount, -180f, 180f);
31.         }
32.  
33.         hph.SetHumanPose(ref hp);
34.  
35.     }
36.  
37. }

as you move the "amount" slider it changes the "muscles" value. I am then setting that to "SetHumanPose", but no change is taking effect. What I thought would happen is that character would move the muscles for example open/close their finger.

 

Anyone have any thoughts?

 

I think it's a bug.

 

oh ? you don't say...

 

In My Project, humanPoseHandler.GetHumanPose(ref pose ) generate float[] with NaN value.
Maybe native code pass wrong ref pointer.

 

Oops. HumanPose is struct , not class. If you create instance in function, function terminate object is dispeared. Because struct object is made in stack memory.
If you use HumanPose then
new HumanPose in class or new in coroutine.

 

1. 1. using UnityEditor;
   2. using UnityEngine;
   3. 
      
   4. [CustomEditor(typeof(Pose))]
   5. public class PoseEditor : Editor {
   6. 
      
   7. HumanPoseHandler hph;
   8. HumanPose hp = new HumanPose();
   9. Avatar avatar;
   10. float[] defaultMuscles;

 

You must put animator.transform into rootbone transform parameter.

Here is my sample code.

using UnityEngine;
using System.Collections;

public class PoseDisplay : MonoBehaviour {

HumanPose pose = new HumanPose();
HumanPoseHandler handler;
public Transform root;

public float[] muscles;
bool playing = false;

public int index;

IEnumerator PoseHandling()
{
pose = new HumanPose();
while (playing )
{
yield return false;
Debug.Log(HumanTrait.MuscleName[index] + " is " + pose.muscles[index]);

}
}

// Use this for initialization
void Start () {
playing = true;
muscles = new float[92];
// StartCoroutine(PoseHandling());
}

void OnDestroy()
{
playing = false;
}

// Update is called once per frame
void LateUpdate () {
// pose.muscles = muscles;

HumanPose targetPose = new HumanPose();
targetPose.bodyPosition = root.position;
targetPose.bodyRotation = root.rotation;
targetPose.muscles = new float [ HumanTrait.MuscleName.Length];
System.Array.Copy( muscles , targetPose.muscles , muscles.Length );

if ( handler == null )
{
handler = new HumanPoseHandler(GetComponent<Animator>().avatar, root);
}

handler.SetHumanPose(ref targetPose);
Debug.Log(HumanTrait.MuscleName[index] + " is " + targetPose.muscles[index]);


}
}

 

I was facing a similar problem. This question might help people here: https://stackoverflow.com/questions...d-head-muscles-using-script/48758353#48758353
