Cave adaptation

Привыкание к пещерам — это механика, которая вызывает неприятные и болезненные ощущения на солнце у дварфов, проводящих слишком много времени под землёй и не выходивших на солнечный свет. Она работает благодаря токену [CAVE_ADAPT].

По мере прогрессирования болезни у дварфа могут появляться негативные мысли "irritated by the sun" и "nauseated by the sun". Последняя приводит к более тяжёлым случаям привыкания к пещерам, и часто дварфа начинает натурально рвать при появлении в освещённом помещении. Впрочем, это не слишком значительная проблема для большинства дварфов, поскольку им нет нужды появляться из-под земли.

Предотвращение и лечение

First and foremost, be aware that cave adaptation requires much more effort to fully eradicate than it's worth. Most dwarves can spend their entire lives lurking in the dark with no negative consequences. Cave adaptation is only a major concern for your military dwarves, as they are the only ones who really need to be functioning at full capacity when outside. Menial labor dwarves sent out to build roads or structures can endure the unpleasant aspects of cave adaptation just fine, while dwarves you regularly send out to fish or gather plants will quickly lose their cave adaptation entirely. Also, note that only dwarves suffer from cave adaptation. If this process sounds like too much effort, you might just want to recruit a few non-dwarven mercenaries for outdoor combat.

Treatment of cave adaptation is accomplished by exposing your dwarves to outdoor sunlight for an extended period of time. Any tile with the Outside trait will suffice, gradually reducing the cave adaptation of any dwarf standing there. This is difficult to cheat - even seemingly-transparent roofs made of grates or glass still cause the tile to be treated as Inside. What will work is building a retractable drawbridge over wherever you want to be outside, opening the drawbridge, channeling down/removing floors, and then closing the drawbridge, although this is probably a bug, as the drawbridge does not need to be made of glass. The progress of treating severe cave adaptation can be observed through a dwarf's Thoughts and Preferences, as limited exposure to sunlight will first convert severe cave adaptation into mild cave adaptation; see personality traits for details.

It takes a lot of sunlight to undo any serious amount of adaptation; a fully cave-adapted dwarf requires 9 weeks of continuous exposure to be fully cured. As such, you'll need to devise entertaining and well-decorated meeting areas to lure your dwarves to the surface and keep them there. Make sure there are plenty of high-value decorations in place, or the negative thoughts associated with being in sunlight will cause your dwarves a lot of stress. Also, be aware that any such zone is ripe for attack by invaders; make sure there are soldiers nearby, surround the site with high walls, and consider building a retractable bridge above it so you can quickly block out the outside world as needed.

For your military, a cheap and sloppy solution is to simply send them outdoors a lot. Attacking the local wildlife is a low-risk exercise that gives your soldiers valuable military training alongside their cave adaptation treatment. Unfortunately, this is not an automated process; letting your dwarves return to the darkness will gradually reestablish their adaptation, and micromanaging your dwarves that much quickly becomes annoying. If you can prevent the reestablishment of cave adaptation, however, the process is much more effective. An alternative strategy is to simply station your dwarves outside for part of the year, using the Scheduling screen.

Cave adaptation can be prevented by keeping your dwarves out of Dark tiles as much as possible. Every moment spent in the dark slightly increases your dwarves' cave adaptation, eradicating the benefits of your surface garden parties, but fortunately these tiles can be converted to harmless Light tiles with nothing more expensive than time, effort, and a large supply of rock blocks. Any tile that has had all its roofing removed becomes an Outside Light tile, the sort which is useful for treating cave adaptation. Building a roof over these tiles replaces the Outside trait with Inside, but leaves the Light trait untouched. These sunlit indoor tiles neither cure nor cause cave adaptation, making them perfect for housing those dwarves who will be heading to the surface often. Once you have a sizable workforce and some well-trained miners, it shouldn't take too long to channel away the top few floors of your fortress and reconstruct them with blocks. Doing this for your entire fortress, however, is almost certainly more work than it's worth. If you have a dedicated squad of soldiers for surface threats and convert their training and living areas to Light tiles, they should be safe from cave adaptation going forward, especially if you are regularly treating them to wildlife hunts and missions abroad.

Механика привыкания к пещерам

• If a dwarf is in a Dark tile, cave adaptation increases by 1 every tick to a maximum of 800,000 (403,200 ticks is one year, so the maximum is just short of 2 years).
• If a dwarf is in an Outside tile, cave adaptation decreases by 10 every tick.
• If a dwarf is in an Outside tile while the sun is out (i.e. not raining or snowing), the following happens:
  • If cave adaptation is between 403,200 and 604,800 (between 1 and 1.5 years), the dwarf will become dizzy and experience minor pain and fatigue. They will also receive the unhappy thought "was irritated by the sun recently".
  • If cave adaptation is at 604,800 or higher (1.5 years), the dwarf will experience nausea, dizziness, pain, and fatigue. They will start vomiting profusely and will also receive the unhappy thought "was nauseated by the sun recently".
  • Otherwise, nothing bad happens.

Negative effects of cave adaptation have a percentage chance to trigger (1/1000 per tick) and they are cumulative, so a sufficiently long string of unlucky rolls can actually cause a cave-adapted dwarf to pass out from exhaustion upon stepping outside. Note that it is possible to get both cave adaptation thoughts at the same time.

Объяснение

Этой статье присвоена категория «Д» — значит «Дварфы». Это значит, что в ней встречаются смешные шутки, не очень смешные шутки, совсем не смешные шутки, всякие внутриигровые приколы и ссылки на форум Bay12. Не верьте всему, что тут понаписали, и не расстраивайтесь, если чего-то не поняли.

Научное объяснение привыкания к пещерам взято с форума форума Bay 12 Games.

В подземелье низкий уровень света и плохая циркуляция воздуха.

У дварфов постепенно развивается зрение, приспособленное к тусклому освещению (толстошлемники содержат бета-каротин!), а их волосы на лице становятся чувствительны к лёгким дуновениям ветра в их бородах, что позволяет им ориентироваться в тоннелях.

Когда они спускаются глубже, то меньше полагаются на глаза, и привыкают больше полагаться на такое волосяное осязание.

В конце концов они становятся настолько чувствительными, что, если дварф рискнёт выйти наружу, обычный ветер для них будет подобен множеству разноцветных вспышек огней. Это раздражает повышенное дварфийское осязание подобно тому, как шоу Tokio Hotel, увиденное в трезвом состоянии, может вызвать тошноту.
