Raycast向后进行，但i编码它可以向前

Question

我尽力而为，但我的射线播放仍然每次都向后倒退 - 请我需要帮助

这里是我的代码 - 基本上，代码射击了一个射线播放的前进按钮以检测敌人，但是射线播放的方式相反。

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

public class milkscript: MonoBehaviour
{
    NavMeshAgent Agent;

    public Transform Point;

    public float raydistance = 40f;
    public float enemyview = 5f;
 
    // Start is called before the first frame update
    void Start()
    {
        Agent = GetComponent<NavMeshAgent>();
    }

    // Update is called once per frame
    void Update()
    {
        RaycastHit Hit;

        if(Physics.Raycast(Point.position,Point.position + Point.forward, out Hit, raydistance)) 
        {
            Debug.DrawRay(Point.position, Hit.transform.forward, Color.red);
            Debug.Log(Hit.transform.name);

            if(Hit.transform.tag == "chcolatemilk") 
            {
                ChasePlayer(Hit.transform);
            }
        }
    }

    public void ChasePlayer(Transform target)
    {
        Agent.SetDestination(target.position);
        transform.LookAt(target.position);
    }
}

我认为这是两个问题的组合

1. ，如您所述

     debug.drawRay（point.position，hit.transform.forward，color.red）;
    

   在hit.transform.forward的方向上绘制射线，这不是您拍摄raycast

   中的原始方向

2. 作为方向 raycast 的原始方向或raycast您正在传递

     point.point.point.point.forward
    

   ，而不是位置。

   您只想通过point.forward作为方向

传递

void Update()
{
    if(Physics.Raycast(Point.position, Point.forward, out var Hit, raydistance)) 
    {
        Debug.DrawLine(Point.position, Hit.transform.position, Color.red);
        // TODO: remove this later! Logging every frame is quite expensive!
        Debug.Log(Hit.transform.name);

        // prefer "CompareTag" over "=="! It is a) slightly faster and b)
        // instead of failing silently throws an error for typos and non-existent tags => better debugging live
        if(Hit.transform.CompareTag("chcolatemilk")) 
        {
            ChasePlayer(Hit.transform);
        }
    }
    Debug.DrawRay(Point.position, Point.forward, Color.green);
}
