`play` · `0x43` · **clientbound** (server → client)

Tells the client that it has entered combat. It has no fields. The vanilla client ignores it; it exists for legacy combat tracking.

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

## Fields

_No fields._

## Send it

```ts
await client.sendPacket("PlayerCombatEnter");
```

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