Question

我发现一个代码在我的游戏中非常有效，可以捡起一个物体并将其扔掉，但是当两个物体相邻时，游戏会同时拾取两个物体，因为它是根据玩家到目标的距离计算得出的对象。

我试图理解射线，但是我无法解决它...

代码如下：

using UnityEngine;
using System.Collections;


public class ThrowObject : MonoBehaviour
{
    public Transform player;
    public Transform playerCam;
    public float throwForce = 10;
    bool hasPlayer = false;
    bool beingCarried = false;

    public AudioClip[] soundToPlay;
    private AudioSource audio;
    public int dmg;
    private bool touched = false;


    void Start()
    {
        audio = GetComponent<AudioSource>();
    }

    void Update()
    {

        float dist = Vector3.Distance(gameObject.transform.position, Input.mousePosition);
        if (dist <= 2.5f)
        {
            hasPlayer = true;
        }
        else
        {
            hasPlayer = false;
        }       


        if (hasPlayer && Input.GetButtonDown("Use"))
        {
            GetComponent<Rigidbody>().isKinematic = true;
            transform.parent = playerCam;
            beingCarried = true;
        }
        if (beingCarried)
        {
            if (touched)
            {
                GetComponent<Rigidbody>().isKinematic = false;
                transform.parent = null;
                beingCarried = false;
                touched = false;
            }
            if (Input.GetMouseButtonDown(0))
                {
                    GetComponent<Rigidbody>().isKinematic = false;
                    transform.parent = null;
                    beingCarried = false;
                    GetComponent<Rigidbody>().AddForce(playerCam.forward * throwForce);
                RandomAudio();
                }
                else if (Input.GetMouseButtonDown(1))
                {
                GetComponent<Rigidbody>().isKinematic = false;
                    transform.parent = null;
                beingCarried = false;
                }
            }
        }
    void RandomAudio()
    {
        if (audio.isPlaying){
            return;
                }
        audio.clip = soundToPlay[Random.Range(0, soundToPlay.Length)];
        audio.Play();

    }
   void OnTriggerEnter()
    {
        if (beingCarried)
        {
            touched = true;
        }
    }
    }

任何帮助将不胜感激。预先谢谢你！

看看OnMouseOver和OnMouseEnter函数 https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnMouseOver.html

如何根据指针位置而不是玩家位置来拾取对象？
