`play` · `0x13` · **clientbound** (server → client)

Updates a numeric property of the open window, such as furnace burn time or progress, brewing stand time, or enchantment table seed and levels. `property` is a window-type-specific index and `value` is the new value. The client updates the displayed progress bars or values.

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

## Fields

| Field | Type | Notes |

  windowId: /* ContainerID */,

  value: /* Short */,
});
