Rock Hermit Beacons
-------------------
v1.3, by Dybal

Most Rock Hermits start as mining communities in an asteroid-rich region, often on a shoestring budget (it's a huge capital investment), with no beacon, or a beacon with very limited range but still useful to find the way home in the asteroid field.

As time goes by, their wealth hopefully goes up and they can afford wider range beacons, which they might need since they have to go further to mine, as the asteroids closer to them become depleted of useful minerals by their mining activities.

Finally, the time comes when there are few useful asteroids around them, and they have the choice of moving on to richer fields, leaving an abandoned rock hermit, or convert into a station-like business, offering servicing, equipment, market, accommodation, etc., for which a still wider range beacon would allow them to attract a larger clientele.

Rock Hermit Beacons OXPs tries to bring the Rock Hermits closer to that story. It:

- adds beacons with diverse ranges, from 50km up to the whole system, to the majority of the Rock Hermits (Pirate Coves included), allowing them to be found through Advanced Space Compass and seen in the 'In-system distances' Station Interface screen (F4);
- adds and maintains an asteroid field around the Rock Hermit, the number of asteroids based on its beacon range.

The beacons are added to the Rock Hermit themselves, no Navigation Buoys are involved.

It doesn't add beacons to all Rock Hermits if finds, since some of them would be true hermits, and desire to be left alone, some would want to keep a low profile and not attract attention (from the government, from the police, from criminal gangs... the reason would vary with the Rock Hermit role and system government's meddling), and some simply can't afford yet to buy and maintain a beacon.


Note for OXP developers
-----------------------


This OXP doesn't create Rock Hermits, it acts on the Rock Hermits it finds, and it waits a bit after startup for other OXPs to create them..

It does three things, and all of them can be controlled by properties in the Rock Hermit's ship.script, so the Rock Hermit's creator can control what this OXP does with its creation.

- The first thing this OXP does is create beacons for the Rock Hermits a few seconds after startup. This can be controlled with the property 'ship.script.$rhbCreateBeacon'; Rock Hermit Beacons OXP will not create beacons on RHs that have this property set to the value "no".

- The second thing this OXP does is create and mantain an asteroid field around the RH. The size of the asteroid field can be controlled through the property 'ship.script.$rhbAsteroidsQtt'.

- Finally, it manages beacon visibility based on their range and the player's ship position. The beacon's range can be defined (in game meters) through 'ship.script.$rhbBeaconRange', and whenever 'ship.script.$rhbCreateBeacon' is "no" Rock Hermit Beacons will not change the beacon's visibility to On even if the beacons's range is defined and the player's ship moves into range, allowing the RH's creator to keep the beacon Off through that property.

Acknownledgments
---------------

This OXP started as a re-write of Eric Walch's Rock Hermit Locator (which was based on Frame's ideas), since it doesn't include a license allowing modification, but it took a life of its own after some suggestions from phkb induced  me to take a step back and look at the bigger picture, so my thanks to Frame, Eric Walch and phkb for the inspiration!

Version history
---------------

Version 1.3
* doesn't add beacons to Astromines (they replace Rock Hermits in Communist systems if Commies OXP is installed, and already have an unlimited beacon).

Version 1.2
* removes timers and resets Rock Hermit list when player's ship enters a wormhole
* renames beep.ogg to rhb_chime.ogg

Version 1.1
* Fixes bug in the handling of timer to repopulate asteroid fields

Version 1.0
* Initial release.
