How could we delete all the anchors inside the room on the server(clear the room) when it's connected to the server (SharingService)?
When we try to import the anchor from the room all the anchors are uploaded (WorldAnchorTransferBatch.ImportAsync). It's just wasting of time. I need just one anchor. How can I clear the room of the anchors or send the request to get the particular anchor?

Either you only export that one specific anchor or you search in your imported anchorbatch for this one specific anchor and only instantiate that one

The WorldAnchorTransferBatch imports all anchors from the room. You can not specify a specific anchor.

Indeed but you can specify which anchor you want to add to your scene

foreach (string id in batchLoaded.GetAllIds())
            {
                if(id == "specificObject")
                {
                    GameObject go = Instantiate(new GameObject());
                    batchLoaded.LockObject(id, go);
                }
            }

                    batchLoaded.LockObject(id, go);
                }
            }

Yes, I know that.
But download 20-40 anchors too long. That's why I want to clean it when I connect to the room.

Reeley

Well the only option you have then is to only export the anchors you want

I'm telling you:
I use(export) different anchors for each session and the same room.
After a while there are many anchors in the room. I need to get rid of them.

Reeley

Are you using the WorldAnchorManager? if so you can remove anchors like this:

WorldAnchorManager.Instance.RemoveAnchor(gameobject);

If you want to delete all anchors, there is a function:

WorldAnchorManager.Instance.RemoveAllAnchors();

It removes anchors from the local store, but not from the server.

Ohhhh now i see. I never fiddled around with Hololens and "multiplayer". I guess you are doing your networking with UNet? if so then you have to send some message to your server and execute the code there.

EDIT:

something like this:

[Command]
    void CmdDeleteAnchorsOnServer()
    {
        WorldAnchorManager.Instance.RemoveAllAnchors();
    }

EDIT2:

are you using this? then i guess the server side has nothing to do with unity

You can also try. But I do not think that will work.
