AR Core 미리 할당된 오브젝트의 위치이동으로 구현하기

터치하면

 

public GameObject ObjPrefab;

 

할당해놓은 오브젝트가 anchor 위치로 이동함.

 

Anchor.cs 열어보면 Anchor가 트레킹 되지않을경우 child Object들은 setActive를 끄는 부분이 존재함. 주의

 

 

public void Update()

        {

            _UpdateApplicationLifecycle();

 

            Touch touch;

            if (Input.touchCount < 1 || (touch = Input.GetTouch(0)).phase != TouchPhase.Began)

            {

                return;

            }

 

            if (EventSystem.current.IsPointerOverGameObject(touch.fingerId))

            {

                return;

            }

 

            TrackableHitFlags raycastFilter = TrackableHitFlags.PlaneWithinPolygon |

                TrackableHitFlags.FeaturePointWithSurfaceNormal;

 

            if (Frame.Raycast(touch.position.x, touch.position.y, raycastFilter, out TrackableHit hit))

            {

                if ((hit.Trackable is DetectedPlane) &&

                    Vector3.Dot(FirstPersonCamera.transform.position - hit.Pose.position,

                        hit.Pose.rotation * Vector3.up) < 0)

                {

                    Debug.Log("Hit at back of the current DetectedPlane");

                }

                else

                {

                    //GameObject prefab;

                    if (hit.Trackable is FeaturePoint)

                        return;

                    

                    var anchor = hit.Trackable.CreateAnchor(hit.Pose);

                    ObjPrefab.transform.parent = anchor.transform;

 

                    Vector3 l_euler = FirstPersonCamera.transform.rotation.eulerAngles;

 

                    l_euler = new Vector3(0f, l_euler.y, 0f);

 

                    ObjPrefab.transform.rotation = Quaternion.Euler(l_euler);

                    ObjPrefab.transform.localPosition = new Vector3(0f, 1f, 0f);

                }

            }

        }
