Question

我试图将多维数据集从A移到B。我正在使用的应用程序使用Unity / ARKit来检测平面。在触摸事件中，它将放置一个多维数据集。目前，这可以按预期进行。

我现在想将放置的立方体转换到新位置，但是我的立方体是固定的。在下面的代码中，我放置了多维数据集。然后，在该if语句中，我调用一个名为MoveToB的方法，该方法应获取名为objectToPlace的GameObject并转换其位置。我认为这是代码出问题的地方。

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

    if (placementPoseIsValid && Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) {
        PlaceObject();
        Debug.Log("Object Placed"); // This gets called
        MoveToB();
    }
}

private void MoveToB()
{
    objectToPlace.transform.position = new Vector3(100, 100, 100);
    Debug.Log("MoveToB Triggered"); // This gets called
}

有人能指出我正确的方向吗？

其余代码...

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 screenCentre = Camera.current.ViewportToScreenPoint(new Vector3(0.5f, 0.5f));
    var hits = new List<ARRaycastHit>();
    arOrigin.Raycast(screenCentre, 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);
    }
}

objectToPlace似乎是预制件？

如果不是

objectToPlace.transform.position = new Vector3(100, 100, 100);

尝试翻译该预制件，而不是翻译您在场景中实例化的对象（克隆）。

相反，您应该存储放置对象的引用

private GameObject spawnedObject;

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

然后移动

private void MoveToB()
{
    spawnedObject.transform.position = new Vector3(100, 100, 100);
    Debug.Log("MoveToB Triggered"); // This gets called
}

转换放置的GameObject的位置
