创建脚本并编写：PetFollowTarget.cs

using UnityEngine;
public class PetFollowTarget : MonoBehaviour{
    Transform target;
    float speed = 2f;
    Animator animator;
    void Start(){
        target = GameObject.Find("PlayerNormal/PetsSmallPos").gameObject.transform;
        animator = GetComponent<Animator>();
    }
    void Update(){
        if (target != null){
            Vector3 direction = target.position - transform.position;
            float distance = direction.magnitude;
            if (distance > 0.1f){
                animator.SetBool("IsIdle", false);
                transform.LookAt(target.position);
                transform.position = Vector3.MoveTowards(transform.position, target.position, speed * Time.deltaTime);
            }
            else{
                animator.SetBool("IsIdle", true);
            }
        }
    }
}
