# llSetScale

*LSL function*

```lsl
void llSetScale(vector size);
```

- `vector size`: Target size vector.

- Energy: 10

Sets the size of the prim according to **size**

The components of **size** (**x**, **y** & **z**) each need to be in the range \[0.01, 64.0\], if they are out of the range they are rounded to the nearest endpoint.

```lsl title="How to use" frame="terminal"
llSetScale(ZERO_VECTOR);
```

## Caveats

- This function only changes the size of the *prim* that the script is in. **Not** the entire object.
- If the prim is part of a link set, rescaling will fail if the new size is too large or small to satisfy the [linkability rules](https://wiki.secondlife.com/wiki/Linkability_Rules).
- Does not work on [physical](/constants/STATUS_PHYSICS/) prims.

## Examples

<summary>Example 1</summary>

```lsl collapse={1-7}
//A basic door that opens and closes when an avatar collides with it.
//Not very effective, as it would be better to use llSetStatus(STATUS_PHANTOM, 1)...
//But, it works.
vector startingSize;
default {
     state_entry() {
          startingSize = llGetScale();
     }
     collision_start(integer i) {
          llSetScale(<0.1, 0.1, 0.1>); //Shrink
          llSetPos(llGetPos() + <0.0,0.0,10.0>); //Hide us
          llSetTimerEvent(3.0);
     }
     timer() {
          llSetTimerEvent(0.0);
          llSetScale(startingSize); //Go back to normal size
          llSetPos(llGetPos() - <0.0,0.0,10.0>); //And where we started
     }
} //Code by Xaviar Czervik.
