title: Chat Ack
description: "Play 0x06, client → server."

`play` · `0x06` · **serverbound** (client → server)

Acknowledges received signed chat messages when the player has not spoken for a while. `count` is the number of messages seen since the last acknowledgement. The server uses it to keep the last-seen message tracker in sync; it is sent when the pending count reaches 64.

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