Vuforia判斷當識別追蹤的對象

  

 方法一，如果有多個識別對象，在Update中循環識別對象數組，獲取TrackableBehaviour組件

foreach (var item in trackObjects)
        {
            var mTrackableBehaviour = item.GetComponent<Vuforia.TrackableBehaviour>();
            if (mTrackableBehaviour != null && (int)mTrackableBehaviour.CurrentStatus>1)
            {
                if (mTrackableBehaviour.transform.name == "追蹤物體的Name")
                    {  }
                Debug.Log("追蹤的物體名字為："+mTrackableBehaviour.Trackable.Name);
                break;
            }
            else
            {
                //
            }
        }

方法二，直接把代碼掛在識別對象上，判斷該對象是否被識別

　　　　　　　var mTrackableBehaviour = GetComponent<Vuforia.TrackableBehaviour>();
            if (mTrackableBehaviour != null && (int)mTrackableBehaviour.CurrentStatus>1)
            {
                if (mTrackableBehaviour.transform.name == "追蹤物體的Name")
                    {  }
                Debug.Log("追蹤的物體名字為："+mTrackableBehaviour.Trackable.Name);
                break;
            }

識別對象狀態枚舉：

public enum Status
        {
            NOT_FOUND = -1,
            UNKNOWN = 0,
            UNDEFINED = 1,
            DETECTED = 2,
            TRACKED = 3,
            EXTENDED_TRACKED = 4,
        }
