linear

coordinate and control movement across linked transport_controllers. allows moving large single multitile platforms and many 1 tile platforms. also is capable of linking platforms across linked z levels

Vars
controller_status	bitfield of various transport states
controls_locked	if true, the platform cannot be manually moved.
create_modular_set	taken from our lift platforms. if true we go through each z level of platforms and attempt to make the lowest left corner platform into one giant multitile object the size of all other platforms on that z level.
ignored_smashthroughs	Typepath list of what to ignore smashing through, controls all lifts
modular_set	whether the lift handled by this transport_controller datum is multitile as opposed to nxm platforms per z level
specific_transport_id	overridable ID string to link control units to this specific transport_controller datum. created by placing a transport id landmark object somewhere on the tram, if its anywhere on the tram we'll find it in init and set this to whatever it specifies
throw_chance	probability of being thrown hard during an emergency stop
transport_id	transport_id taken from our base lift platform, used to put us into SStransport.transports_by_type
transport_modules	the lift platforms we consider as part of this transport. ordered in order of lowest z level to highest z level after init. (the sorting algorithm sucks btw)
z_sorted	lift platforms have already been sorted in order of z level.
Procs
Check_lift_move	Check destination turfs
check_for_landmarks	check for any landmarks placed inside the locs of the given transport_module
controls_lock	Sets transport controls_locked state. Used to prevent moving mid movement, or cooldowns.
create_modular_set_for_z_level	goes through all platforms in the given list and finds the one in the lower left corner
finish_simple_move_wrapper	Wrap everything up from simple_move_wrapper finishing its movement
get_platforms_on_level	returns all transport modules associated with this transport on the given z level or given atoms z level
get_zs_we_are_on	Returns a list of all the z-levels our transport is currently on.
link_transport_modules	Collect all bordered platforms via a simple floodfill algorithm. allows multiz trams because its funny
move_after_delay	Moves the platform after a passed delay.
move_lift_vertically	Moves the platform UP or DOWN, this is what users invoke with their hand. This is a SAFE proc, ensuring every part of it moves SANELY.
move_to_zlevel	Moves the platform to the passed z-level.
move_transport_horizontally	Moves the platform, this is what users invoke with their hand. This is a SAFE proc, ensuring every part of the lift moves SANELY. It also locks controls for the (miniscule) duration of the movement, so the elevator cannot be broken by spamming.
open_lift_doors_callback	Helper used in callbacks to open all the doors our platform is on
order_platforms_by_z_level	orders the lift platforms in order of lowest z level to highest z level.
reset_lift_contents	resets the contents of all platforms to their original state in case someone put a bunch of shit onto the platform. intended to be called by admins. passes all arguments to reset_contents() for each of our platforms.
return_closest_platform_to	returns the closest transport to the specified atom, prioritizing transports on the same z level. used for comparing distance
return_closest_platform_to_z	Returns a platform on the z-level which is vertically closest to the passed target_z
set_info_from_id_landmark	set vars and such given an overriding transport_id landmark
simple_move_wrapper	Simple wrapper for checking if we can move 1 zlevel, and if we can, do said move. Locks controls, closes all doors, then moves the platform and re-opens the doors afterwards.
update_lift_doors	Updates all blast doors and shutters that share an ID with our lift.

Proc Details

proc
Check_lift_move
(check_dir)

Check destination turfs

proc
check_for_landmarks
(/obj/structure/transport/linear/new_transport_module)

check for any landmarks placed inside the locs of the given transport_module

proc
controls_lock
(state)

Sets transport controls_locked state. Used to prevent moving mid movement, or cooldowns.

proc
create_modular_set_for_z_level
(/list/obj/structure/transport/linear/platforms_in_z)

goes through all platforms in the given list and finds the one in the lower left corner

proc
finish_simple_move_wrapper
()

Wrap everything up from simple_move_wrapper finishing its movement

proc
get_platforms_on_level
(/atom/atom_reference_OR_z_level_number)

returns all transport modules associated with this transport on the given z level or given atoms z level

proc
get_zs_we_are_on
()

Returns a list of all the z-levels our transport is currently on.

proc
link_transport_modules
(/obj/structure/transport/linear/base_transport_module)

Collect all bordered platforms via a simple floodfill algorithm. allows multiz trams because its funny

proc
move_after_delay
(lift_move_duration, door_duration, direction, /mob/user)

Moves the platform after a passed delay.

This is a more "user friendly" or "realistic" move. It includes things like:

Allowing platform "travel time"
Shutting elevator safety doors
Sound effects while moving
Safety warnings for anyone below the platform (while it's moving downwards)

Arguments: duration - required, how long do we wait to move the platform? door_duration - optional, how long should we wait to open the doors after arriving? If null, we won't open or close doors direction - which direction are we moving the lift? user - optional, who is moving the lift?

proc
move_lift_vertically
(going, /mob/user)

Moves the platform UP or DOWN, this is what users invoke with their hand. This is a SAFE proc, ensuring every part of it moves SANELY.

Arguments: going - UP or DOWN directions, where the platform should go. Keep in mind by this point checks of whether it should go up or down have already been done. user - Whomever made the movement.

proc
move_to_zlevel
(target_z, /datum/callback/loop_callback, /mob/user)

Moves the platform to the passed z-level.

Checks for validity of the move: Are we moving to the same z-level, can we actually move to that z-level? Does NOT check if the controls are currently locked.

Moves to the passed z-level by calling move_after_delay repeatedly until the passed z-level is reached. This proc sleeps as it moves.

Arguments: target_z - required, the Z we want to move to loop_callback - optional, an additional callback invoked during the loop that allows the move to cancel. user - optional, who started the move

proc
move_transport_horizontally
(going)

Moves the platform, this is what users invoke with their hand. This is a SAFE proc, ensuring every part of the lift moves SANELY. It also locks controls for the (miniscule) duration of the movement, so the elevator cannot be broken by spamming.

proc
open_lift_doors_callback
()

Helper used in callbacks to open all the doors our platform is on

proc
order_platforms_by_z_level
()

orders the lift platforms in order of lowest z level to highest z level.

proc
reset_lift_contents
(consider_anything_past, foreign_objects, foreign_non_player_mobs, consider_player_mobs)

resets the contents of all platforms to their original state in case someone put a bunch of shit onto the platform. intended to be called by admins. passes all arguments to reset_contents() for each of our platforms.

Arguments:

consider_anything_past - number. if > 0 our platforms will only handle foreign contents that exceed this number in each of their locs
foreign_objects - bool. if true our platforms will consider /atom/movable's that arent mobs as part of foreign contents
foreign_non_player_mobs - bool. if true our platforms consider mobs that dont have a mind to be foreign
consider_player_mobs - bool. if true our platforms consider player mobs to be foreign. only works if foreign_non_player_mobs is true as well

proc
return_closest_platform_to
(/atom/comparison, allow_multiple_answers)

returns the closest transport to the specified atom, prioritizing transports on the same z level. used for comparing distance

proc
return_closest_platform_to_z
(target_z)

Returns a platform on the z-level which is vertically closest to the passed target_z

proc
set_info_from_id_landmark
(/obj/effect/landmark/transport/transport_id/landmark)

set vars and such given an overriding transport_id landmark

proc
simple_move_wrapper
(direction, lift_move_duration, /mob/user)

Simple wrapper for checking if we can move 1 zlevel, and if we can, do said move. Locks controls, closes all doors, then moves the platform and re-opens the doors afterwards.

Arguments: direction - which direction are we moving? lift_move_duration - how long does the move take? can be 0 or null for instant move. door_duration - how long does it take for the doors to open after a move? user - optional, who moved it?

proc
update_lift_doors
(on_z_level, action)

Updates all blast doors and shutters that share an ID with our lift.

Arguments: on_z_level - optional, only open doors on this z-level or list of z-levels action - how do we update the doors? CYCLE_OPEN to make them open, CYCLE_CLOSED to make them shut
