title: Set Simulation Distance
description: "Play 0x6F, server → client."
---

`play` · `0x6F` · **clientbound** (server → client)

Tells the client the server's simulation distance. The server sends it on join and when the value changes. The client uses it to decide which entities and chunks to tick locally.

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