[NetCode] How to get RTT?

[paolo_simone_enovia]

Hi,

I’m currently stuck on this (apparently?) simple task: I want to show on screen the Round Trip Time (RTT) (aka Latency, Ping…) of packets from client to server, similar to what is shown in NetDbg tool

I’ve digged in the documentation but I found only indirect references:

• NetworkTimeSystem contains an estimated TimestampMS of the server time from the client, computed using (also) RTT… but from that alone am not able to derive RTT
  link: Time synchronization | Unity NetCode | 0.1.0-preview.6

• Computing difference between ClientSimulationSystemGroup.ServerTick (estimated tick on server?) and ClientSimulationSystemGroup.InterpolationTick (last received tick from server?) brought me nowhere

• I found a RTT computation in multiplayer/Soaker sample but it seems a bit overcomplicated

Is there a simple way of accessing or computing RTT (and possibly other network stats)?

Thank you, any help is appreciated

Don’t know if there is a better way, but this seems to work:

Entities.ForEach((ref NetworkSnapshotAckComponent ack) =>
{
    var rtt = ack.EstimatedRTT;
    // ...
});
