When you open up KS and mouse over an installed level, the Difficulty, Size and Category are all displayed, regardless of whether the level designer used a default setting for each field or a custom one. It's perfectly possible to have a level display "Difficulty: Purple, Size: Monkey, Category: Bingo" for example. (Useless, but possible.) I haven't seen anything to indicate that the level archive would definitely not be able to display this same information.
As for searching, no, as of right now, neither KS itself nor the in-progress level archive support being able to search for custom categories (though I understand there's at least one KS mod which does support this).
This is fine. It is not necessary to be able to search for Scenic-tagged levels for the Scenic category to be useful. Because the custom category tag will still display normally -- certainly in KS, and as far as I know in the forthcoming level archive as well -- all we need is to come to some community consensus about what to call the levels this thread is about, either "Scenic" or something else that covers the sense of "Environmental" as it's come to be (incorrectly) used.
Since levels can have two categories, and much of the issue with misuse of the Environmental tag has been that it's by definition mutually exclusive with Challenge and Puzzle, this means that users will be able to find the type of level they want by searching (so long as the designer didn't designate
only the custom Scenic category and no second category) for Challenge, Puzzle, Playground or whatever other sort of level they're looking for, and just look for the levels
within the displayed results which are
also tagged Scenic
in addition to the searchable category.
Obviously it would be most helpful if the level archive LPChip is working on will indeed display whatever categories each level is tagged with the way KS itself does for installed levels, but even if it doesn't (and again, LPChip is not taking any suggestions at this time, so let's not badger him, hm?) just being able to spot the Scenic levels in one's own installed-levels listing will be a good thing.
The category field in the archive is presumably currently read from the level itself
Yes, and this is exactly why having Scenic remain a custom category, rather than an official one, will work just fine. If the level designer puts Scenic in either the Category A field or the Category B field, then
the Scenic tag will be read by the game and, hopefully, the archive as well. It may not be possible to search on Scenic as a category; but that, again, is fine.
Just a reminder, although levels whose world.ini list both Environmental and either Challenge or Puzzle are going to be rejected by the new archive automatically, according to Nifflas's definition an Environmental cannot contain any challenges, puzzles,
or enemies... which means that quite a few excellent levels currently on the archive tagged Environmental only (or Environmental/Misc. or Environmental/Playground) are actually Scenic levels -- that is, they are "Environmental" only in the sense which the community has come to use the term to mean, which brings us back again to the reason why we need to settle on a term other than Environmental for these levels. Well-known examples include Flood*, Gaia, and Knytt on the Moon. (Contrast with Dark Waters, a 'true' Environmental despite having no encoded category designation.) While these levels could be re-uploaded to the new archive as-is, it seems far more useful to players (especially players who don't visit these forums, which do not show up in search-engine results nearly as readily as the level archive itself does) for only levels which actually meet the official definition of Environmental to be tagged as such. Scenic is self-explanatory enough that someone new to KS and/or unfamiliar with the forums shouldn't have to scratch their head too much over what it could mean.
I'm now going to briefly break my own rule -- though I still think this should be its own separate topic -- to touch on the idea of an Adventure category. I'm not actually sure whether Neotrice and Exp HP mean story-focussed levels in general, or quest-type levels in particular. Nifflas's own The Machine, A Strange Dream and An Underwater Adventure are what I would consider
quest-type levels, whereas the gold standard (IMO) of a
story-focussed level is Egomassive's A Knytt in Time -- though Alamaster Moody's The Outsider is a very different kind of level that is nevertheless equally story-driven. If we're going to have a consensus-termed custom category name for the latter type of level, too, I propose we follow JayIsGames.com's lead and call the genre of "
story-games"
Narrative... another self-explanatory word. "Adventure" as a category name might be too broad, as there are very few levels which
couldn't be considered an adventure of some kind.
As far as getting Nifflas to OK adding one or more level categories to KS 1.2.2 or 1.3.1 or whatever it would be numbered, asking him about that is certainly an option, and if he were to say yes then the issue of level-archive (and in-game) searchability would be resolved also, yes.
But let's not put the cart before the horse. I'd like to see a lot more players and level designers weigh in on what they would like their that-other-Environmental levels' categories to be called, and I'd like to give people at least a month or two of opportunity to find this thread and weigh in. I don't think the new archive is ready for imminent release, so there's no rush. I imagine that, if we wait until we A) build a strong community consensus for both what to call the new category (or categories), and B) hammer out a clear definition of what that category does and does not include, as well as C) pointing to specific existing levels which are caught in the non-Environmental-Environmental morass, we're more likely to get a positive response. Just PM'ing him and saying, "Please add these categories to Knytt Stories!" is unlikely to get us anywhere.
It may not have enemies in the usual sense, but it does have
