Select Known Packs (clientbound)

Configuration 0x0E, server → client.

config · 0x0E · clientbound (server → client)

Lists the data packs (namespace, id, version) whose registry contents the server expects the client to know. Sent at the start of configuration. The client replies with its own SelectKnownPacks listing the packs it actually has, and the server then trims RegistryData accordingly.

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

Send it

await client.sendPacket("SelectKnownPacks", {
  knownPacks: [
    { namespace: "minecraft", id: "core", version: "26.2" },
  ],
});

Offer packs whose registry contents the client may already know. The client returns the subset it has in its serverbound SelectKnownPacks; use that answer when deciding which RegistryData entries may omit data.

Field aliases listed under Notes are accepted as alternative keys when writing.
