Var Details

always_lit

Bool, whether this turf will always be illuminated no matter what area it is in

archived_cycle

used to determine whether we should archive

atmos_adjacent_turfs

list of turfs adjacent to us that air can flow onto

atmos_supeconductivity

bitfield of dirs in which we are superconducitng

directional_opacity

Which directions does this turf block the vision of, taking into account both the turf's opacity and the movable opacity_sources.

dynamic_lumcount

Lumcount added by sources other than lighting datum objects, such as the overlay lighting component.

fixed_underlay

Icon-smoothing variable to map a diagonal wall corner with a fixed underlay.

heat_capacity

Amount of heat necessary to activate some atmos processes (there is a weird usage of this var because is compared directly to the temperature instead of heat energy)

holodeck_compatible

the holodeck can load onto this turf if TRUE

initial_gas_mix

used for mapping and for breathing while in walls (because that's a thing that needs to be accounted for...) string parsed by /datum/gas/proc/copy_from_turf approximation of MOLES_O2STANDARD and MOLES_N2STANDARD pending byond allowing constant expressions to be embedded in constant strings If someone will place 0 of some gas there, SHIT WILL BREAK. Do not do that.

lighting_corner_NE

Lighting Corner datums.

lighting_object

Our lighting object.

opacity_sources

Lazylist of movable atoms providing opacity sources.

overfloor_placed

If there's a tile over a basic floor that can be ripped out

rcd_memory

If this turf contained an RCD'able object (or IS one, for walls) but is now destroyed, this will preserve the value. See _DEFINES/construction.dm for RCD_MEMORY*.

temperature_archived

Archived version of the temperature on a turf

Proc Details

Initialize

Turf Initialize

Doesn't call parent, see /atom/proc/Initialize Please note, space tiles do not run this code. This is done because it's called so often that any extra code just slows things down too much If you add something relevant here add it there too /turf/open/space/Initialize

LinkBlockedWithAccess

For seeing if we can actually move between 2 given turfs while accounting for our access and the caller's pass_flags

Arguments:

ScrapeAway

Take off the top layer turf and replace it with the next baseturf down

add_opacity_source

Proc to add movable sources of opacity on the turf and let it handle lighting code.

air_update_turf

A helper proc for dealing with atmos changes

Ok so this thing is pretty much used as a catch all for all the situations someone might wanna change something About a turfs atmos. It's real clunky, and someone needs to clean it up, but not today. Arguments:

clear_signal_refs

WARNING WARNING Turfs DO NOT lose their signals when they get replaced, REMEMBER THIS It's possible because turfs are fucked, and if you have one in a list and it's replaced with another one, the list ref points to the new turf We do it because moving signals over was needlessly expensive, and bloated a very commonly used bit of code

conductivity_directions

SUPERCONDUCTIVITY ALLLLLLLLLLLLLLLLLLLLRIGHT HERE WE GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Read the code for more details, but first, a brief concept discussion/area

Our goal here is to "model" heat moving through solid objects, so walls, windows, and sometimes doors. We do this by heating up the floor itself with the heat of the gasmix ontop of it, this is what the coeffs are for here, they slow that movement Then we go through the process below.

If an active turf is fitting, we add it to processing, conduct with any covered tiles, (read windows and sometimes walls) Then we space some of our heat, and think about if we should stop conducting.

consider_superconductivity

Should we attempt to superconduct?

expose_reagents

Handles exposing a turf to reagents.

fromShuttleMove

Base procs

get_atmos_adjacent_turfs

returns a list of adjacent turfs that can share air with this one. alldir includes adjacent diagonal tiles that can share air with both of the related adjacent cardinal tiles

is_blocked_turf

Check whether the specified turf is blocked by something dense inside it with respect to a specific atom.

Returns truthy value TURF_BLOCKED_TURF_DENSE if the turf is blocked because the turf itself is dense. Returns truthy value TURF_BLOCKED_CONTENT_DENSE if one of the turf's contents is dense and would block a source atom's movement. Returns falsey value TURF_NOT_BLOCKED if the turf is not blocked.

Arguments:

is_blocked_turf_ignore_climbable

Checks whether the specified turf is blocked by something dense inside it, but ignores anything with the climbable trait

Works similar to is_blocked_turf(), but ignores climbables and has less options. Primarily added for jaunting checks

is_nearby_planetary_atmos

Runs through all adjacent open turfs and checks if any are planetary_atmos returns true if even one passes.

neighbor_conduct_with_src

These two procs are a bit of a web, I belive in you

reachableAdjacentTurfs

Returns adjacent turfs to this turf that are reachable, in all cardinal directions

Arguments:

recalculate_directional_opacity

Calculate on which directions this turfs block view.

remove_opacity_source

Proc to remove movable sources of opacity on the turf and let it handle lighting code.

return_turf_delta_p

Finds the greatest difference in pressure across a turf, only considers open turfs.

wash

Called when this turf is being washed. Washing a turf will also wash any mopable floor decals
