当骑在移动平台上时，玩家以不稳定的方式移动

Question

我有一个移动平台脚本，可以在三个位置之间移动。这很好。

我有一个将播放器保存到平台的脚本，这也很好。

但是当我通过移动平台脚本将我的播放器固定到一个对象的平台时，播放器的移动是不稳定且不均匀的。

以下是我正在使用的脚本：

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

public class MovingMultipalPoint : MonoBehaviour
{

    public Vector3 pointB;
    public Vector3 pointC;
    public float Second = 5.0f;
    public float Speed = 3.0f;
    //public float HoldSecond = 5.0f;

    IEnumerator Start()
    {
        Vector3 pointA = transform.position;
        while (true)
        {
            yield return new WaitForSeconds(Second);
            yield return StartCoroutine(MoveObject(transform, pointA, pointB, Speed));
            yield return new WaitForSeconds(Second);
            yield return StartCoroutine(MoveObject(transform, pointB, pointC, Speed));
            yield return new WaitForSeconds(Second);
            yield return StartCoroutine(MoveObject(transform, pointC, pointB, Speed));
            yield return new WaitForSeconds(Second);
            yield return StartCoroutine(MoveObject(transform, pointB, pointA, Speed));
        }
    }

    IEnumerator MoveObject(Transform thisTransform, Vector3 startPos, Vector3 endPos, float time)
    {
        float i = 0.0f;
        float rate = 1.0f / time;
        while (i < 1.0f)
        {
            i += Time.deltaTime * rate;
            //newRotation *= Quaternion.Euler(0, 90, 0);
            //transform.rotation = Quaternion.Slerp(transform.rotation, newRotation, 20 * Time.deltaTime);
            thisTransform.position = Vector3.Lerp(startPos, endPos, i);
            yield return null;
        }
    }
}

此脚本将播放器保存到平台。

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

public class HoldPlayer : MonoBehaviour
{
    private GameObject target = null;
    private Vector3 offset;
    void Start()
    {
        target = null;
    }
    void OnTriggerStay(Collider col)
    {
        target = col.gameObject;
        offset = target.transform.position - transform.position;
    }
    void OnTriggerExit(Collider col)
    {
        target = null;
    }
    void LateUpdate()
    {
        if (target != null)
        {
            target.transform.position = transform.position + offset;
        }
    }
}

在这种情况下我是如何保持运动顺畅的？
