title: Game Test Highlight Pos
description: "Play 0x28, server → client."
---

`play` · `0x28` · **clientbound** (server → client)

Highlights a block position for the game test framework, with an absolute position and a relative position within the test structure. It is used only by the internal game test tooling. Normal clients do not need to handle it.

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

## Fields

| Field | Type | Notes |
|---|---|---|
| `absolutePos` | Position | also `absoluteLocation` |
| `relativePos` | Position | also `relativeLocation` |

## Send it

```ts
await client.sendPacket("GameTestHighlightPos", {
  absolutePos: /* Position */,
  relativePos: /* Position */,
});
```

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