VR开发的Point控制脚本和一个样例脚本

Example.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using VRStandardAssets.Utils;

public class Example : MonoBehaviour {
	VRInteractiveItem vritem;
	//动态添加vritem
	void Awake(){
		if (!gameObject.GetComponent <VRInteractiveItem> ()) {
			gameObject.AddComponent <VRInteractiveItem> ();
		}
		vritem = gameObject.GetComponent <VRInteractiveItem> ();
	}
	//两个生命周期函数注册Handle事件
	void OnEnable(){
		vritem.OnOver += HandleOver;
		vritem.OnOut += HandleOut;
		vritem.OnClick += HandleClick;
	}
	void OnDisable(){
		vritem.OnOver -= HandleOver;
		vritem.OnOut -= HandleOut;
		vritem.OnClick -= HandleClick;
	}
	//判断触发条件	如果视线在当前物体上并且点击事件触发
	void Update(){
		if(vritem.IsOver&&PointCtl.point.isclick){
			HandleClick ();
		}
	}
	//Handle事件处理
	//视线在当前物体上时开启计时
	void HandleOver(){
		print ("[进入]"+name);
		PointCtl.point.isover = true;
	}
	//视线在当前物体上时开启计时
	void HandleOut(){
		print ("[退出]"+name);
		PointCtl.point.isover = false;
	}
	//倒计时结束后的点击事件
	void HandleClick(){
		print ("[单击]"+name);
		PointCtl.point.Init ();
	}

}

PointCtl.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using VRStandardAssets.Utils;
public class PointCtl : MonoBehaviour {
	[SerializeField]Image ring;						//环
	[SerializeField]VRInteractiveItem vritem;		//vritem
	public static PointCtl point;					//单例
	public float timer=3.0f;						//计时
	public bool isover=false;						//isover标志位来开启计时
	public bool isclick= false;						//计时完毕之后触发HandleClick事件
	void Awake(){
		point = this;
		if (!gameObject.GetComponent <VRInteractiveItem> ()) {
			gameObject.AddComponent <VRInteractiveItem> ();
		}
		vritem = GetComponent <VRInteractiveItem> ();
	}
	void Update(){
		//视线进入物体
		if(isover){
			ring.fillAmount += Time.deltaTime / timer;
			if(ring.fillAmount>=1){
				isclick = true;
			}
		}
		//视线从物体上移开
		else{
			Init ();
		}

	}
	public void Init(){
		ring.fillAmount = 0;
		isover = false;
		isclick = false;
	}
}
