public XRNode NodeType;
public Vector3 ObjectGrabOffset;
public waft GrabDistance = 0.1f;
public string GrabTag = "Snatch";
public waft ThrowMultiplier=1.5f;
non-public Turn into _currentObject;
non-public Vector3 _lastFramePosition;
// Use this for initialization
void Get started()
// Replace is named as soon as in step with body
void Replace()
//update hand place and rotation
become.localPosition = InputTracking.GetLocalPosition(NodeType);
become.localRotation = InputTracking.GetLocalRotation(NodeType);
//if we do not have an lively object in hand, glance if there's one in proximity
if (_currentObject == null)
//we have now object in hand, update its place with the present hand place (+outlined offset from it)
