首先看一下效果

using UnityEngine;using UnityEngine.AI;// Use physics raycast hit from mouse click to set agent destination[RequireComponent(typeof(NavMeshAgent))]public class ClickToMove : MonoBehaviour{    NavMeshAgent m_Agent;    RaycastHit m_HitInfo = new RaycastHit();    public LineRenderer _lineRenderer;    void Start()    {        m_Agent = GetComponent<NavMeshAgent>();    }    void Update()    {        if (Mathf.Abs(m_Agent.remainingDistance) < 1.5f)        {            _lineRenderer.positionCount = 0;            _lineRenderer.gameObject.SetActive(false);        }        if (_lineRenderer.gameObject.activeInHierarchy)        {            Vector3[] _path = m_Agent.path.corners;//储存路径            var path = _path;            _lineRenderer.SetVertexCount(_path.Length);//设置线段数            for (int i = 0; i < _path.Length; i++)            {                Debug.Log(i + "= " + _path[i]);                _lineRenderer.SetPosition(i, _path[i]);//设置线段顶点坐标            }        }        if (Input.GetMouseButtonDown(0) && !Input.GetKey(KeyCode.LeftShift))        {            var ray = Camera.main.ScreenPointToRay(Input.mousePosition);            if (Physics.Raycast(ray.origin, ray.direction, out m_HitInfo))            {                m_Agent.destination = m_HitInfo.point;                //m_Agent.Stop();                _lineRenderer.gameObject.SetActive(true);            }        }    }}
