# llSleep

*LSL function*

```lsl
void llSleep(float sec);
```

- `float sec`: Duration in seconds to put the script to sleep.

- Energy: 0

Puts the script to sleep for **sec** seconds. The script will not do anything during this time.

The script will sleep at least until the next server-frame, which happen every (1/45 = ~0.02222) seconds under normal conditions.

If **sec** is zero or less, the script will not sleep at all.

```lsl title="How to use" frame="terminal"
llSleep(0.0);
```
