Metaio获取当前追踪的对象的方法

  重写 onTrackingEvent获取TrackingValues集合，然后通过TrackingValues的state属性的isTrackingState()方法判断是否为追踪状态，或者直接使用state状态来判断。

state状态枚举：

public enum TrackingState
    {
        Unknown = 0,
        NotTracking = 1,
        Tracking = 2,
        Lost = 3,
        Found = 4,
        Extrapolated = 5,
        Initialized = 6,
         Registered = 7,
        InitializationFailed = 8
    }

判断追踪状态代码：

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

public class QRCodeReader : metaioCallback
{

    
    override protected void onTrackingEvent(List<TrackingValues> trackingValues)
    {
        
        foreach (TrackingValues tv in trackingValues)
        {
            Debug.Log(tv.state);
            //istrackingstate trackingvalues
            
            if (tv.state.isTrackingState())
            {              
　　　　　　　　　　 //
            }
           
        }
    }
}
