Unity XR Interaction Toolkit 获取手中拿到的物体_unity xrrayinteractor trygetcurrent3draycasthit

方法一：  通过射线获取，缺点会获取到 射线与已抓取物体之间的物体

 public XRRayInteractor rRayInteractor;  
 
  bool state = rRayInteractor.TryGetCurrent3DRaycastHit(out RaycastHit raycastHit3D);
  if (raycastHit3D.transform)
  {
      Debug.Log("transform :" + raycastHit3D.transform.name);
  }

方法二：

 List<IXRSelectInteractable> selectList = rRayInteractor.interactablesSelected;
 if (selectList != null &&  selectList.Count >0)
 {
     foreach (IXRSelectInteractable item in selectList)
     {
         Debug.Log("============="+item.transform.name+"=====");
         
     }
 }
