(유니티) 뷰포리아 마커 인식 이벤트 설정

public class TargetTracker : MonoBehaviour, ITrackableEventHandler

mTrackableBehaviour = GetComponent<TrackableBehaviour>();
            if (mTrackableBehaviour)
            {
                mTrackableBehaviour.RegisterTrackableEventHandler(this);
            }

ITrackableEventHandler의 OnTrackableStateChanged 메소드를 구현해야 한다.(이부분에서 마커 트렉킹에 대한 정보가 나온다)

public void OnTrackableStateChanged(TrackableBehaviour.Status previousStatus, TrackableBehaviour.Status newStatus)
        {
            print("Test");
            if (newStatus == TrackableBehaviour.Status.DETECTED || newStatus == TrackableBehaviour.Status.TRACKED ||
                       newStatus == TrackableBehaviour.Status.EXTENDED_TRACKED)
            {
                print("TargetTracker : onTrackingFound");
                OnTrackingFound();
            }
            else
            {
                print("TargetTracker : onTrackingLost");
                OnTrackingLost();
            }
        }
