要让代码控制IK，需要先在Animator中打开IK pass

 

 

然后，和IK相关的代码需要放到相应的函数中去：

void OnAnimatorIK(){    Debug.Log("OnAnimatorIK");}

 

而如果是StateMachineBehaviour，IK操控的代码是在：

public override void OnStateIK(Animator animator, AnimatorStateInfo stateInfo, int layerIndex){    base.OnStateIK(animator, stateInfo, layerIndex);    Debug.Log("OnStateIK");}

 

测试脚本：

using UnityEngine;using System.Collections;public class IKTest : MonoBehaviour{    public Animator animator;    public Transform ikTarget;    void OnAnimatorIK()    {        animator.SetIKPosition(AvatarIKGoal.LeftFoot, ikTarget.position);        animator.SetIKPositionWeight(AvatarIKGoal.LeftFoot, 1);    }}
