`play` · `0x7B` · **clientbound** (server → client)

Returns the NBT data of a block or entity that the client requested with `BlockEntityTagQuery` or `EntityTagQuery`. `transactionId` matches the request. The client uses it for creative-mode Ctrl+pick block copying of NBT.

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

## Fields

| Field | Type | Notes |

## Send it

await client.sendPacket("TagQuery", {
  transactionId: /* VarInt */,
  nbt: /* writeAnonOptionalNbt */,
});
```

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