Turfs have a variable, intact, which conflates three meanings:
Determining whether there's something that can be pried out, such as directly with a crowbar or indirectly with a tile stack and a crowbar off-hand.
Determining whether underfloor pieces are visible.
Determining whether underfloor pieces can be interacted with - by players with tools, through interaction with effects like chemical acid, or foam.
When plating is hit with a stack of tiles, /turf/open/floor/attackby checks whether the turf is intact, and if so, ends the attack chain regardless of whether or not the attempt to hotswap a turf (with a crowbar) is successful or not. However, turfs which want the underfloor to be visible - such as catwalks and glass - set the intact variable to FALSE, and so can be repeatedly placed over one another, as if they were the first tile to be placed over the plating.
This refactors /turf/var/intact into two distinct variables:
/turf/var/overfloor_placed, for whether or not there is something over plating.
/turf/var/underfloor_visible, for whether or not the various underfloor pieces should be invisible, visible, or both visible and interactable.
All references to /turf/var/intact have been replaced with an equivalent overfloor_placed or underfloor_visible reference, depending on which check is appropriate. underfloor_accessibility can take one of UNDERFLOOR_HIDDEN, UNDERFLOOR_VISIBLE, or UNDERFLOOR_INTERACTABLE. This prevents cases such as acid foam or tools phasing through glass floors to affect the underfloor pieces underneath, and covers all kinds of unusual, not-wiring-visiblity usage such as Holodeck completeness, Revenant interaction, or station integrity checking.
Simple_animals / mobs are the biggest lie in this code-base. They're far from simple and have an extreme god-object problem. Especially when you get to /hostile, where there is so many procs, vars, and what not, that you can't make any interesting additions without snowflaking the hell out of the code.
This PR hopes to help kill this problem by introducing a new /living subtype, /living/basic. The idea of this refactor is to slowly start moving all old simple_animals to this new system, moving over behaviors like charging and more extravagant mobs like megafauna over bit by bit similar to how newfood was implemented.
One of the other big goals of this refactor is to move many of the fringe simple animal behaviors into either AI datums, or components/elements. (Some of which still needs to be done in this PR).
As a proof of concept, I created the base mob/living/basic, and moved cockroaches over to the system. Since cockroaches have both a passive, melee and ranged mob.
This PR does slightly affect balance as the behavior isn't 1-on-1 due to it no longer running on the janky /hostile behavior, but I tried to keep the effects to a minimum, and the glockroach and hauberoach are not spawnable through many means as far as I know.
* Cleans up some unused procs and makes is_blocked_turf a turf proc.
* Update code/game/turfs/turf.dm

🆑
tweak: Ducts can now be hidden under tiles
code: tile hiding is now an element and way cooler and sexier
/🆑
Ducts can now be hidden under tiles
Plumbing machinery connects can now be hidden aswell
Plumbing can now also be properly mapped in without breaking anything
Plumbing component now uses the normal overlay systeem instead of being a weird exception
You can now add the /datum/element/undertile element to instantly make something hidable under tiles when appropriate.
