navmeshagent角色移动对象

Question

我试图控制游戏中的对象（例如立方体），并使用由导航网格物体代理控制的第三人称角色与它们一起移动。主要目的是能够在某种程度上抓住立方体（或使立方体与玩家互动时紧贴玩家）并随其移动，最后将立方体放置在卡车后面。当玩家在放置积木时与立方体互动（在卡车后面）时，应出于优化目的而破坏或隐藏该立方体。就像我之前说过的，我的播放器由导航网格物体控制，并具有胶囊和刚性容器，并且我现在有一个交互脚本附加到其他对象上，玩家可以在其中拾取/收集物品，这些物品在我的库存中隐藏并显示插槽。但是与我要实现的目标不同，这些目标是不可动摇的。在此先感谢我希望我能理解（我正在使用Unity 2018.2）。以下是相关代码：

[Code = CSharp]

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

[RequireComponent(typeof(NavMeshAgent))]
public class PlayerMotor : MonoBehaviour
{

    Transform target;           //Target to follow
    NavMeshAgent agent;         //Referance to agent
    // Use this for initialization
    void Start()
    {
        agent = GetComponent<NavMeshAgent>();
    }

    void Update()
    {
        if(target != null)
        {
            agent.SetDestination(target.position);
            FaceTarget();
        }
    }

    public void MoveToPoint(Vector3 point)
    {
        agent.SetDestination(point);
    }

    public void FollowTarget(Interactable newTarget)
    {
        agent.stoppingDistance = newTarget.radius * .8f;
        agent.updateRotation = false;

        target = newTarget.interactionTransform;
    }

    public void StopFollowingTarget()
    {
        agent.stoppingDistance = 0f;
        agent.updateRotation = true;

        target = null;
    }

    void FaceTarget()
    {
        Vector3 direction = (target.position - transform.position).normalized;
        Quaternion lookRotation = Quaternion.LookRotation(new Vector3(direction.x, 0f, direction.z));

        if(direction != Vector3.zero)
        {
            transform.rotation = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * 5f);
        }

    }
