How to modify a collider according to a bone?

Hello.

I use FBX model on Unity.
The FBX model has some bones include named "Body"

it is definitions of SkinnedMeshRenderer and MeshCollider on C#.

Code (csharp):

1.  
2. private SkinnedMeshRenderer  renderer; 
3. private MeshCollider collider;
4.  

I also attached MeshFilter and added some codes in the Start().

Code (csharp):

1.  
2. void Start () {
3.     renderer = gameObject.GetComponent<SkinnedMeshRenderer>();
4.     collider = gameObject.GetComponent<MeshCollider>();
5.     Mesh meshFilter = gameObject.GetComponent<MeshFilter>().mesh;
6.     collider.sharedMesh = meshFilter;
7.  

It is code snippet about modifying bone.
After that It will change mesh.

Code (csharp):

1.  
2. foreach (Transform bone in renderer.bones) {
3.     if (bone.name == "Body") {
4.         bone.position = Vector3(x, y, z); // variable x, y, z are assigned some values
5.     }
6. }
7.  

then, MeshCollider didn't change.
So, I also would like to change the MeshCollider according to the Body bone.


I saw the URL
http://forum.unity3d.com/threads/32467-How-to-update-a-mesh-collider

I added the scripts below. but not work

Code (csharp):

1.  
2. void LateUpdate () {
3.     renderer = gameObject.GetComponent<SkinnedMeshRenderer>();
4.     collider = null;
5.     collider = gameObject.GetComponent<MeshCollider>();
6.     collider.sharedMesh = renderer.sharedMesh;
7. }
8.  

Could you tell me how to write codes?

I'm afraid my English isn't understandable

 

does it disable?

 

I'm afraid it is multipost. I will ask japanese community.
but, I'm not sure how to delete the thread..
