Loop

This commands starts a looping sound, e.g. a waterfall in a nature scene. Up to 5 loop sounds can be used simultaneously in the area. Use for instance

```
WHEN SOMEONE IN VICINITY THEN LOOP WATER

```

You can optionally set the volume by providing a percentage (the "%" can be omitted from the number if you want; use values of up to 500.0):

```
WHEN SOMEONE IN VICINITY THEN LOOP WATER WITH 80%

```

Looped sounds can also be made heard in the whole area by either setting the Thing "..." → "Surround Sound" attribute, or using the "surround" with-keyword:

```
WHEN STARTS THEN LOOP WINTER WIND WITH SURROUND

```

You can also get a mix between local 3D spatial sound + whole-area surround sound via the "half-surround" keyword. It will give some indicator of direction and distance while still being heard everywhere:

```
WHEN STARTS THEN LOOP WINTER WIND WITH HALF-SURROUND

```

* The placements distance optimizer will always ensure Surround Sound things are active.

To stop the loop again, use "end loop".

* Note there's also global area environment/ weather settings, some coming with their own background sounds. Open the Area dialog (the mountain & sun icon) to set them. As opposed to such environment sounds, the loop command sounds will have the 3d audio source be from the Thing Part itself, the volume shrinking as one gets further away.
