`play` · `0x18` · **serverbound** (client → server)

Sent when the player edits or signs a writable book. `hand` is the hand holding the book, `pages` are the new page texts, and `title` is present only when signing. The server replaces the book item, converting it to a written book if a title is given.

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

## Fields

| Field | Type | Notes |
|---|---|---|
| `hand` | VarInt | also `slot` |
| `pages` | Array | also `entries` |
| `title` | Optional |  |

## Send it

```ts
await client.sendPacket("EditBook", {
  hand: /* VarInt */,
  pages: /* Array */,
  title: /* Optional */,
});
```

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