/datum/air_group

Air groups are collections of tiles that let us save processing time by treating a bunch of similar tiles as a single tile. This is quite useful because atmospherics processing is quite the time hog and processing one tile is much faster. Whenever our tiles become too different, we can break up and create new smaller groups.

Vars
air	The gas mixture we use for the air group.
archived_cycle	Cycle that our archived vars were made. The use of archived cycle saves processing power by permitting the archiving step of FET to be rolled into the updating step.
border_group	Groups that border us and are in group processing mode.
border_individual	Tiles that border us that either have no group, aka singletons, or are not in group processing mode.
borders	Our tiles that border this group to other groups/singletons.
current_cycle	Current cycle of the atmospherics master.
enemies	Tiles that border us and are in another group that is currently processing.
group_processing	Processing all tiles as one large tile if TRUE.
length_space_border	Length of our border with space
members	All tiles in this group
self_group_borders	Our tiles that border groups that are processing.
self_tile_borders	Our tiles that border singletons.
space_borders	Tiles that border space
spaced	If true, will drain the gasses of the airgroup.
Procs
check_regroup
process_group	Process the various air groups.
resume_group_processing	Collect air from the members to the group.
space_fastpath
space_group	Zeroes and spaces the air of the group and resumes group processing.
suspend_group_processing	Distribute air from the group out to members
unspace_group	Unspaces the group and stops group processing.
update_group_from_tiles	Copy group air information to individual tile air. Used right before turning on group processing.
update_tiles_from_group	Copy group air information to individual tile air. Used right before turning off group processing.

Var Details

var
air
– /tmp/datum/gas_mixture

The gas mixture we use for the air group.

var
archived_cycle
– /tmp

Cycle that our archived vars were made. The use of archived cycle saves processing power by permitting the archiving step of FET to be rolled into the updating step.

var
border_group
– /list/datum/air_group

Groups that border us and are in group processing mode.

var
border_individual
– /list/turf/simulated

Tiles that border us that either have no group, aka singletons, or are not in group processing mode.

var
borders
– /list/turf/simulated

Our tiles that border this group to other groups/singletons.

var
current_cycle
– /tmp

Current cycle of the atmospherics master.

var
enemies
– /list/turf/simulated

Tiles that border us and are in another group that is currently processing.

var
group_processing
– /tmp

Processing all tiles as one large tile if TRUE.

var
length_space_border
–

Length of our border with space

var
members
– /list/turf/simulated

All tiles in this group

var
self_group_borders
– /list/turf/simulated

Our tiles that border groups that are processing.

var
self_tile_borders
– /list/turf/simulated

Our tiles that border singletons.

var
space_borders
– /list/turf/simulated

Tiles that border space

var
spaced
–

If true, will drain the gasses of the airgroup.

Proc Details

proc
check_regroup
()

If individually processing tiles, checks all member tiles to see if they are close enough that the group may resume group processing.
Returns: False if group should not continue processing, TRUE if it should.
Warning: Do not call, called by air_master.process()

proc
process_group
(/datum/controller/process/parent_controller)

Process the various air groups.

proc
resume_group_processing
()

Collect air from the members to the group.

proc
space_fastpath
(/datum/controller/process/parent_controller)

If group processing is off, and the air group is bordered by a space tile, execute a fast evacuation of the air in the group.
If the average pressure in the group is < 5kpa, the group will be zeroed.
Returns: TRUE if the group is zeroed, FALSE if not.

proc
space_group
()

Zeroes and spaces the air of the group and resumes group processing.

proc
suspend_group_processing
()

Distribute air from the group out to members

proc
unspace_group
()

Unspaces the group and stops group processing.

proc
update_group_from_tiles
()

Copy group air information to individual tile air. Used right before turning on group processing.

proc
update_tiles_from_group
()

Copy group air information to individual tile air. Used right before turning off group processing.
