atom

A grouping of tiles into a logical space, mostly used by map editors

Vars

firealarms	A list of all fire alarms in this area. Used by firelocks and burglar alarms to change icon state.
firedoors	A list of all fire locks in this area. Used by fire alarm panels when resetting fire locks or activating all in an area
forced_ambience	Does this area immediately play an ambience track upon enter?
lighting_effects	List of mutable appearances we underlay to show light In the form plane offset + 1 -> appearance to use

static_lighting	Whether this area allows static lighting and thus loads the lighting objects
totalbeauty	All beauty in this area combined, only includes indoor area.
turfs_by_zlevel	List of all turfs currently inside this area as nested lists indexed by zlevel. Acts as a filtered version of area.contents For faster lookup (area.contents is actually a filtered loop over world) Semi fragile, but it prevents stupid so I think it's worth it
turfs_to_uncontain_by_zlevel	turfs_by_z_level can hold MASSIVE lists, so rather then adding/removing from it each time we have a problem turf We should instead store a list of turfs to REMOVE from it, then hook into a getter for it There is a risk of this and contained_turfs leaking, so a subsystem will run it down to 0 incrementally if it gets too large This uses the same nested list format as turfs_by_zlevel
