[유니티] 뷰포리아(Vuforia) SDK를 이용한 오브젝트 트레킹 체크

using UnityEngine;

using Vuforia;

public class TrackingObject : MonoBehaviour, ITrackableEventHandler {

private TrackableBehaviour mTrackableBehaviour;

public bool is_detected = false;

// Use this for initialization

void Start () {

mTrackableBehaviour = GetComponent<TrackableBehaviour> ();

if (mTrackableBehaviour) {

mTrackableBehaviour.RegisterTrackableEventHandler (this);

}

}

public void OnTrackableStateChanged(TrackableBehaviour.Status previousStatus, TrackableBehaviour.Status newStatus) {

if (newStatus == TrackableBehaviour.Status.DETECTED || newStatus == TrackableBehaviour.Status.TRACKED) {

is_detected = true;

} else {

is_detected = false;

}

}

}

ITrackableEventHandler  를 상속받고 OnTrackableStateChanged 메소드로 구현 하시면 됩니다.

DETECTED, TRACKED가 물체가 인식되었을 때 입니다.
