Vars
affecting_lights	List of light sources affecting this turf.
atmos_environment	The external environment that this tile is exposed to for ATMOS_MODE_EXPOSED_TO_ENVIRONMENT
atmos_mode	The general behavior of atmos on this tile.
atmos_superconductivity	makes turfs less picky about where they transfer gas. Largely just used in the SM
corners	A list of our lighting corners.
destination_x	The destination x-coordinate that atoms entering this turf will be automatically moved to.
destination_y	The destination y-coordinate that atoms entering this turf will be automatically moved to.
destination_z	The destination z-level that atoms entering this turf will be automatically moved to.
dynamic_lighting	Handles if the lighting should be dynamic. Generally lighting is dynamic if it's not in space
fixed_underlay	Icon-smoothing variable to map a diagonal wall corner with a fixed underlay.
has_opaque_atom	Not to be confused with opacity, this will be TRUE if there's any opaque atom on the tile.
lighting_corners_initialised	If you're curious why these are TMP vars, I don't know! TMP only affects savefiles so this does nothing :) - GDN Is the lighting on this turf inited
lighting_object	The lighting Object affecting us
oxygen	Properties for open tiles (/floor) All the gas vars, on the turf, are meant to be utilized for initializing a gas datum and setting its first gas values; the turf vars are never further modified at runtime; it is never directly used for calculations by the atmospherics system.
pathing_pass_method	How pathing algorithm will check if this turf is passable by itself (not including content checks). By default it's just density check. WARNING: Currently to use a density shortcircuiting this does not support dense turfs with special allow through function
pressure_difference	The pressure difference between the turf and it's neighbors. Affects movables by pulling them in the path of least resistance
pressure_direction	The direction movables should travel when affected by pressure. Set to the biggest difference in atmos by turf neighbors
pressure_overlay	The effect used to render a pressure overlay from this tile.
real_layer	Set if the turf should appear on a different layer while in-game and map editing, otherwise use normal layer.
transparent_floor	used to check if pipes should be visible under the turf or not
Procs
AdjacentTurfs	Returns the adjacent turfs. Can check for density or cardinal directions only instead of all 8, or just dense turfs entirely. dense_only takes precedence over open_only.
LinkBlockedWithAccess	For seeing if we can actually move between 2 given turfs while accounting for our access and the caller's pass_flags
blind_release_air	Blindly releases air to this tile. Do not use if you care what the tile previously held, implement /datum/milla_safe instead.
can_cross_safely	Returns whether it is safe for an atom to move across this turf TODO: Things like lava will need to have more specialized code but that can wait for when we port basic mobs that may actually encounter lava
get_decals	Returns a list of all attached /datum/element/decal/ for this turf
get_readonly_air	Gets a read-only version of this tile's air. Do not use if you intend to modify the air later, implement /datum/milla_safe instead.
private_unsafe_get_air	Do not call this directly. Use get_readonly_air or implement /datum/milla_safe.
private_unsafe_recalculate_atmos_connectivity	This method is unsafe to use because it only updates milla_* properties, but does not write them to MILLA. Use recalculate_atmos_connectivity() instead.

Proc Details

proc
AdjacentTurfs
(open_only, cardinal_only, dense_only)

Returns the adjacent turfs. Can check for density or cardinal directions only instead of all 8, or just dense turfs entirely. dense_only takes precedence over open_only.

proc
LinkBlockedWithAccess
(/turf/destination_turf, /datum/can_pass_info/pass_info)

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

Assumes destinantion turf is non-dense - check and shortcircuit in code invoking this proc to avoid overhead. Makes some other assumptions, such as assuming that unless declared, non dense objects will not block movement. It's fragile, but this is VERY much the most expensive part of pathing, so it'd better be fast

Arguments:

destination_turf - Where are we going from where we are?
pass_info - Holds all the info about what this path attempt can go through

proc
blind_release_air
(/datum/gas_mixture/air)

Blindly releases air to this tile. Do not use if you care what the tile previously held, implement /datum/milla_safe instead.

proc
can_cross_safely
(/atom/movable/crossing)

Returns whether it is safe for an atom to move across this turf TODO: Things like lava will need to have more specialized code but that can wait for when we port basic mobs that may actually encounter lava

proc
get_decals
()

Returns a list of all attached /datum/element/decal/ for this turf

proc
get_readonly_air
()

Gets a read-only version of this tile's air. Do not use if you intend to modify the air later, implement /datum/milla_safe instead.

proc
private_unsafe_get_air
()

Do not call this directly. Use get_readonly_air or implement /datum/milla_safe.

proc
private_unsafe_recalculate_atmos_connectivity
()

This method is unsafe to use because it only updates milla_* properties, but does not write them to MILLA. Use recalculate_atmos_connectivity() instead.
