如何在一组航点之间移动一个对象，并在每个航点面向下一个航点平稳缓慢地旋转？

Question

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

public class Waypoints : MonoBehaviour
{
    public List<Vector3> points = new List<Vector3>();

    // Start is called before the first frame update
    void Start()
    {
        points.Add(transform.position); 
    }

    // Update is called once per frame
    void Update()
    {
        for (int i = 0; i < points.Count; i++)
        {
            transform.position = Vector3.Lerp(points[i], pos2, (Mathf.Sin(speed * Time.time) + 1.0f) / 2.0f);
        }
    }
}

第一个航点是变换(移动物体)的位置，所以当游戏运行时，变换会移动到第一个航点，如果需要的话，它会先面向第一个航点缓慢旋转，然后再移动到该航点。当变换物到达下一个（第一个）航点时，它将面向下一个航点缓慢旋转，同时移动到下一个航点。以此类推，直到航点结束；然后再从下一轮开始，第一个航点将是列表中不转移原始位置的第一个第二点。原来的位置只在第一轮中作为航点使用。

我试过这样做，但是对象ToPatrol的移动是结结巴巴的，不是直接移动到第一个航点，而是移动到第一个航点，但也是向上移动。

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

public class Waypoints : MonoBehaviour
{
    public Transform[] waypoints;
    public float waypointRadius = 1.5f;
    public float damping = 0.1f;
    public bool loop = false;
    public float speed = 2.0f;
    public bool faceHeading = true;
    public GameObject objectToPatrol;

    private Vector3 currentHeading, targetHeading;
    private int targetwaypoint;
    private Transform xform;
    private bool useRigidbody;
    private Rigidbody rigidmember;


    // Use this for initialization
    protected void Start()
    {
        if (objectToPatrol == null)
        {
            xform = transform;
        }
        else
        {
            xform = objectToPatrol.transform;
        }

        currentHeading = xform.forward;
        if (waypoints.Length <= 0)
        {
            Debug.Log("No waypoints on " + name);
            enabled = false;
        }
        targetwaypoint = 0;
        if (GetComponent<Rigidbody>() != null)
        {
            useRigidbody = true;
            rigidmember = GetComponent<Rigidbody>();
        }
        else
        {
            useRigidbody = false;
        }
    }


    // calculates a new heading
    protected void FixedUpdate()
    {
        targetHeading = waypoints[targetwaypoint].position - xform.position;

        currentHeading = Vector3.Lerp(currentHeading, targetHeading, damping * Time.deltaTime);
    }

    // moves us along current heading
    protected void Update()
    {
        if (useRigidbody)
            rigidmember.velocity = currentHeading * speed;
        else
            xform.position += currentHeading * Time.deltaTime * speed;
        if (faceHeading)
            xform.LookAt(xform.position + currentHeading);

        if (Vector3.Distance(xform.position, waypoints[targetwaypoint].position) <= waypointRadius)
        {
            targetwaypoint++;
            if (targetwaypoint >= waypoints.Length)
            {
                targetwaypoint = 0;
                if (!loop)
                    enabled = false;
            }
        }
    }


    // draws red line from waypoint to waypoint
    public void OnDrawGizmos()
    {
        Gizmos.color = Color.red;
        if (waypoints == null)
            return;
        for (int i = 0; i < waypoints.Length; i++)
        {
            Vector3 pos = waypoints[i].position;
            if (i > 0)
            {
                Vector3 prev = waypoints[i - 1].position;
                Gizmos.DrawLine(prev, pos);
            }
        }
    }
}

第一个问题是，我想在航点之间移动的对象有一个Animator组件，而Animator使它结结巴巴。有什么方法可以让Animator保持启用并平滑地移动它，我的意思是，它将继续播放对象动画，在这种情况下，闲置但也平滑地移动它？

Answer 1

你可以尝试使用 Vector3.MoveTowards 而不是 targetHeading 和 currentHeading，像这样。

var newPosition = Vector3.MoveTowards(transform.Position, waypoints[targetwaypoint].position, Time.deltaTime * speed);

if (useRigidbody)
     rigidmember.MovePosition(newPosition);
else
     xform.position.position = newPosition;

至于第二个问题，你可以尝试把动画游戏对象 放在一个空的游戏对象中，然后把脚本放在父对象上。
