title: Set Experience
description: "Play 0x67, server → client."

`play` · `0x67` · **clientbound** (server → client)

Sets the player's experience bar fill, level and total experience. The server sends it when the player gains or loses experience. The client updates the XP bar and level display.

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

## Fields

| Field | Type | Notes |
|---|---|---|
| `experienceBar` | Float |  |
| `level` | VarInt |  |
| `totalExperience` | VarInt |  |

## Send it

```ts
await client.sendPacket("SetExperience", {
  experienceBar: 0.5, // 0 to 1
  level: 30,
  totalExperience: 1395,
});
```

`experienceBar` fills the bar, `level` is the number shown on it. `totalExperience` is the raw point total and only matters for the client's own bookkeeping.

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