# llSetLocalRot

*LSL function*

```lsl
void llSetLocalRot(rotation rot);
```

- `rotation rot`: Local rotation to set.

- Delay: 0.2 s
- Energy: 10

Sets the rotation of a child prim relative to its root prim using rot.

Sets the rotation of a child prim relative to the root prim

```lsl title="How to use" frame="terminal"
llSetLocalRot(ZERO_ROTATION);
```

## Examples

<details open>
<summary>Drop this script into a *child* prim to rotate it in 1 degree increments on each [touch](/events/touch/).</summary>

```lsl collapse={1-11}
rotation rot_xyzs;

default
{
    state_entry()
    {
        vector xyz_angles = <0,1.0,0>; // This defines a 1 degree change on the Y axis
        vector angles_in_radians = xyz_angles*DEG_TO_RAD; // Change to radians
        rot_xyzs = llEuler2Rot(angles_in_radians); // Convert to a rotation
    }

    touch_start(integer s)
    {
        llSetLocalRot(llGetLocalRot()*rot_xyzs); // Apply the increment rotation to the prim's current rotation ...

    }
}
```

</details>

## Helper functions

```lsl
//-- this is an equivalent call from any prim in the same link set
llSetLinkPrimitiveParamsFast( target_prim, [PRIM_ROT_LOCAL, rot] );
//-- where "target_prim" is the link number of the prim you want to set the local rotation of
