# llGroundSlope

*LSL function*

```lsl
vector vector llGroundSlope(vector offset);
```

- `vector offset`: Offset relative to the prim's position, expressed in local coordinates.

- Returns: `vector`
- Energy: 10

Returns a vector representing the ground slope directly below the prim's position offset by the vector offset.

Returns a [vector](https://wiki.secondlife.com/wiki/vector) that is the ground slope below the object [position](/functions/llGetPos/) + **offset**

```lsl title="How to use" frame="terminal"
