camerachunk

A 16x16 grid of the map with a list of turfs that can be seen, are visible and are dimmed.
Allows Camera Eyes to stream these chunks and know what it can and cannot see.

Vars
active_static_images	images currently in use on obscured turfs.
cameras	cameras that can see into our grid indexed by the z level of the camera
obscuredTurfs	turfs our cameras cant see but are inside our grid. associative list of the form: list(obscured turf = static image on that turf)
seenby	Camera mobs that can see turfs in our grid
turfs	list of all turfs, associative with that turf's static image turf -> /image
update_sources	List of atoms that caused the chunk to update - assoc atom ref() to opacity on queue
visibleTurfs	turfs our cameras can see inside our grid
Procs
New	Create a new camera chunk, since the chunks are made as they are needed.
add	Add a camera eye to the chunk, updating the chunk if necessary.
force_update	Forces the chunk to update immediately
queue_update	Queues the chuck to be updated after a delay.
remove	Remove a camera eye from the chunk
update	The actual updating. It gathers the visible turfs from cameras and puts them into the appropiate lists.

Proc Details

New
(x, y, lower_z)

Create a new camera chunk, since the chunks are made as they are needed.

proc
add
(/mob/eye/camera/eye)

Add a camera eye to the chunk, updating the chunk if necessary.

proc
force_update
(only_if_necessary)

Forces the chunk to update immediately

only_if_necessary - if TRUE, will not update the chunk unless it's been marked to update.

proc
queue_update
(/atom/update_source, update_delay_buffer)

Queues the chuck to be updated after a delay.

update_source - the atom that caused the update
update_delay_buffer - the delay before the update is performed. Defaults to 0 (instant).

proc
remove
(/mob/eye/camera/ai/eye)

Remove a camera eye from the chunk

proc
update
()

The actual updating. It gathers the visible turfs from cameras and puts them into the appropiate lists.
