Question

我正在尝试将放置指示器放置在平面上，并在用户轻击时将对象放置在指示器的位置，但是指示器在垂直平面上消失了。

我尝试使用默认平面，但它确实检测到垂直平面

这是我的代码

    void Start()
    {
        arOrigin = FindObjectOfType<ARSessionOrigin>();
    }

    void Update()
    {
        UpdatePlacementPose();
        UpdatePlacementIndicator();

        if (placementPoseIsValid && Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
        {
            PlaceObject();
        }
    }

    private void PlaceObject()
    {
        Instantiate(objectToPlace, placementPose.position, placementPose.rotation);
    }

    private void UpdatePlacementIndicator()
    {
        if (placementPoseIsValid)
        {
            placementIndicator.SetActive(true);
            placementIndicator.transform.SetPositionAndRotation(placementPose.position, placementPose.rotation);
        }
        else
        {
            placementIndicator.SetActive(false);
        }
    }

    private void UpdatePlacementPose()
    {
        var screenCenter = Camera.current.ViewportToScreenPoint(new Vector3(0.5f, 0.5f));
        var hits = new List<ARRaycastHit>();
        arOrigin.Raycast(screenCenter, hits, TrackableType.Planes);

        placementPoseIsValid = hits.Count > 0;
        if (placementPoseIsValid)
        {
            placementPose = hits[0].pose;

            var cameraForward = Camera.current.transform.forward;
            var cameraBearing = new Vector3(cameraForward.x, 0, cameraForward.z).normalized;
            placementPose.rotation = Quaternion.LookRotation(cameraBearing);
        }
    }
}

Answer 1

更改此行代码：

arOrigin.Raycast(screenCenter, hits, TrackableType.Planes);

具有：

arOrigin.Raycast(screenCenter, hits, TrackableType.All);

应该没事的。
