`play` · `0x64` · **clientbound** (server → client)

Attaches or detaches a lead between an entity and its holder. The server sends it when a leash is attached (`vehicleId` is the holder) or removed (`vehicleId` is -1). The client renders the lead.

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

## Fields

## Send it

await client.sendPacket("SetEntityLink", {
  entityId: /* Int */,
  vehicleId: /* Int */,
});
```
