基于Pico在Unity开发中点击事件及检测的功能实现

Pico在Unity开发中点击事件及检测的功能实现

一、创建RayCtrl脚本并挂载在（射线检测参考主页中射线检测的文章，这边不做过多解释）

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

public class RayCtrl : MonoBehaviour
{

    private LineRenderer line;
    public GameObject NowGameObject;

    private GameObject StartPos;
    public static Vector3 hitPos;
    public Transform dot;

    private RaycastHit hit;

    public static string name;

    // Use this for initialization
    void Start()
    {
        line = transform.Find("ray_LengthAdaptive").GetComponent<LineRenderer>();
        line.gameObject.SetActive(true);
        dot = transform.Find("dot");
        dot.gameObject.SetActive(true);
        StartPos = GameObject.Find("StartPos");
        hitPos = Vector3.zero;
    }

    // Update is called once per frame
    void Update()
    {
        Ray ray = new Ray { origin = StartPos.transform.position, direction = StartPos.transform.forward };
        line.SetPosition(0, ray.origin);
        if (Physics.Raycast(ray, out hit, 1000))
        {
            line.SetPosition(1, hit.point);
            line.startColor = Color.green;
            dot.position = hit.point;
            hitPos = hit.point;
            NowGameObject = hit.transform.gameObject;
            name = NowGameObject.name;
        }
        else
        {
            line.SetPosition(1, ray.origin + ray.direction * 2);
            line.startColor = Color.red;
            dot.position = ray.origin + ray.direction * 2;
            hitPos = ray.origin + ray.direction * 2;
            name = null;
        }
    }
}

具体如下图：

二、创建代码GameObjectManager

为了方便检测，我这里写了一个鼠标左键点击的检测。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Pvr_UnitySDKAPI;

public class GameObjectManager : MonoBehaviour
{


    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (RayCtrl.name == this.gameObject.name)
        {
            if (Input.GetMouseButton(0) || Controller.UPvr_GetKey(1, Pvr_KeyCode.TRIGGER))
            {

              //这里写需要的功能

            }
        }
    }
}

这里为了测试，我写了一个旋转事件。

将GameObjectManager脚本添加到需要进行交互的物体上（物体身上必须要有碰撞体）

测试效果如图 ：

到这里，Pico在Unity开发中点击事件及检测的功能实现就已经完成，可以根据自己的需求来写。关注一下，不迷路，下一节，我会为粉丝们讲解Pico手柄常见交互功能的代码。
