MonoBehaviour.OnAnimatorIK(int)

Parameters

Description

Callback for setting up animation IK (inverse kinematics).

OnAnimatorIK() is called by the Animator Component immediately before it updates its internal IK system. This callback can be used to set the positions of the IK goals and their respective weights.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    float leftFootPositionWeight;
    float leftFootRotationWeight;
    Transform leftFootObj;

    private Animator animator;

    void Start()
    {
        animator = GetComponent<Animator>();
    }

    void OnAnimatorIK(int layerIndex)
    {
        animator.SetIKPositionWeight(AvatarIKGoal.LeftFoot, leftFootPositionWeight);
        animator.SetIKRotationWeight(AvatarIKGoal.LeftFoot, leftFootRotationWeight);
        animator.SetIKPosition(AvatarIKGoal.LeftFoot, leftFootObj.position);
        animator.SetIKRotation(AvatarIKGoal.LeftFoot, leftFootObj.rotation);
    }
}
