title: Pong Response
description: "Play 0x3E, server → client."
---

`play` · `0x3E` · **clientbound** (server → client)

Answers a serverbound PingRequest in the play state by echoing the long `id` (usually a timestamp). The client uses the round trip time to measure latency. This is separate from the Ping/Pong pair used for packet ordering.

Sent by the server, read by the client. Listen for it with `client.on("PongResponse", (data) => …)` on the receiving side.
