UNET equivalent of NetworkMessageInfo.timestamp

With the old networking NetworkMessageInfo.timestamp was used to determine how long a packet spent in transit and then you could do some prediction using that information.

But how do I find how long a packet spent in transit using this new networking system?

 

gsus725 I don't know the answer, but there is a community at irc.freenode.net in the channel #unity3d-unet that might have some answers!

In addition some resources and code snippets are being gathered here:

It's not exactly the same but you can get the RTT NetworkClient.GetRTT.

You can also get the network timestamp and add it to your messages manually NetworkTransport.GetNetworkTimestamp.

 

It is not working again, returning 0 over long distance network on 5.6.2f1

 

HLAPI or LLAPI?

 

I think it's HLAPI

 

I think that might be part of the issue. Works for me in LLAPI

 

It does not work on clients.

 

What do you mean? Basically, to use those methods. You need to get the LLAPI connectionId. And I don't think you can get that from HLAPI. Not sure though.

 

You can.

It not working on clients seems to be already a known bug.

 

bump

The current code would return zero

It's not working if you trying to get stamp from the Server message on your client.

 

It works only on server->client . The network timeStamp is available on server and GetRemoteDelay work on client.

If you send NetworkTimeStamp from client to server it will not work, same for client to client. You need to synchronize server timeStamp to all clients and to send that synchronized value with your message.

 

Actually it's not working server-> client, but it works client -> server, I mean you could get round trip of message from client on server side, but you cannot get it from server message on client side.

 

but thanks. I get that I should not synchronize the Time.time
