当NPC或物品点击时对角色进行动画处理

Question

我在youtube上找到了与NPC和物品互动的教程。我的问题是，一旦单击NPC或物品，如何为我的角色设置动画。我希望角色前进到NPC或物品。我只是感到困惑，应该在哪里放置脚本以动画角色的行走或奔跑。

如您所见，有两个盒子，分别是NPC和一个物品。因此，当我右键单击框时，它应该是步行的，它将在npc和item旁边停止。我该怎么办？

WorldInteraction

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class WorldInteraction : MonoBehaviour {
    NavMeshAgent playerAgent;

    void Start() {
        playerAgent = GetComponent<NavMeshAgent>();
    }

    void Update() {
        if (Input.GetMouseButtonDown(0) && !UnityEngine.EventSystems.EventSystem.current.IsPointerOverGameObject()) {
            GetInteraction();
        }
    }

    void GetInteraction() {
        Ray interactionRay = Camera.main.ScreenPointToRay (Input.mousePosition);
        RaycastHit interactionInfo;
        if(Physics.Raycast(interactionRay, out interactionInfo, Mathf.Infinity)) {
            GameObject interactedObject = interactionInfo.collider.gameObject;
            if (interactedObject.tag == "Interactable Object") {
                interactedObject.GetComponent<Interactable>().MoveToInteraction(playerAgent);
            } else {
                playerAgent.destination = interactionInfo.point;
            }
        }
    }
}

可交互

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class Interactable : MonoBehaviour {
    public NavMeshAgent playerAgent;

    public virtual void MoveToInteraction(NavMeshAgent playerAgent) {
        this.playerAgent = playerAgent;
        playerAgent.destination = this.transform.position;

        Interact();
    }

    public virtual void Interact() {
        Debug.Log ("Interacting with base class.");
    }
}

NPC

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class NPC : Interactable {

    public override void Interact() {
        Debug.Log ("Interacting with NPC.");
    }
