Pico click event and detection function implementation in Unity development
1. Create a RayCtrl script and mount it (ray detection refers to the article on ray detection on the homepage, so I won’t explain too much here)
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;
}
}
}
The details are as follows:
2. Create code GameObjectManager
For the convenience of detection, I wrote a detection of left mouse button click here.
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
}
}
}
}
Here for testing, I wrote a rotation event.
Add the GameObjectManager script to the object that needs to interact (the object must have a collision body)
The test effect is shown in the figure:
