title: Ticking State
description: "Play 0x7F, server → client."
---

`play` · `0x7F` · **clientbound** (server → client)

Tells the client the server's tick rate and whether ticking is frozen. The server sends it on join and when `/tick` changes the rate or freezes the game. The client matches its own simulation speed.

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

## Fields
