title: Resource Pack Push
description: "Play 0x51, server → client."
---

`play` · `0x51` · **clientbound** (server → client)

Asks the client to download and apply a resource pack identified by UUID, URL and hash. The server can mark it as required and add a prompt message. The client replies with `ResourcePack` status packets (accepted, downloaded, applied, failed, declined); if the pack is required and declined, the client is disconnected.

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