OnAnimatorIK() only works on the same GameObject?

I'm trying to have a wrapper object control the Animator IK but it doesn't seem to work. The OnAnimatorIK() is not called unless its on the same object as the Animator component. I suppose it makes sense.

I suppose the only way to handle this is to have a proxy which is placed with the Animator that handles the OnAnimatorIK() pass while i control variables from the parent object's scripts?

Example code I'm using below. Is there a different way to do this or do I need to make a proxy?

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class IKthing : MonoBehaviour
6. {
7.     public Transform objToPickUp;
8.     public GameObject goWithAnimator;
9.     private Animator animator;
10.  
11.     void Start()
12.     {
13.         animator = goWithAnimator.GetComponent<Animator>();
14.     }
15.     void OnAnimatorIK()
16.     {
17.         Debug.Log("Doing IK pass.");
18.         float reach = 1f;
19.         animator.SetIKPositionWeight(AvatarIKGoal.RightHand, reach);
20.         animator.SetIKPosition(AvatarIKGoal.RightHand, objToPickUp.position);
21.     }
22. }

 

Right, we didn't want to broadcast the callback to other game object because it could decrease performance.

You can make a proxy on your animator's game object that forward all your OnAnimatorIK to another script.

 

Yep, I moved forward with that. Thanks for confirming. =)

 

Very sorry to revive this post but how does one "make a proxy on your animator's game object that forward all your OnAnimatorIK to another script"?
