base_icon_state

Used for changing icon states for different base sprites.

bottom_left_corner

Smoothing variable

bottom_right_corner

Smoothing variable

bubble_icon

What icon the mob uses for speechbubbles

canSmoothWith

List of smoothing groups this atom can smooth with. If this is null and atom is smooth, it smooths only with itself.

can_pathfind_pass

How this atom should react to having its astar blocking checked

chat_color

Last color calculated for the the chatmessage overlays. Used for caching.

chat_color_name

Last name used to calculate a color for the chatmessage overlays. Used for caching.

drag_start

Contains the world.time of when we start dragging something with our mouse. Used to prevent weird situations where you fail to click on something

For handling persistent filters

flags_ricochet

how the atom should handle ricochet behavior

germ_level

The higher the germ level, the more germ on the atom.

This atom's HUD (med/sec, etc) images. Associative list.

hud_possible

HUD images that this atom can provide.

light_power

Intensity of the light. Can be negative to remove light

managed_overlays

overlays managed by update_overlays to prevent removing overlays that weren't added by the same proc. Single items are stored on their own, not in a list.

map_json_data

This var isn't actually used for anything, but is present so that DM's map reader doesn't forfeit on reading a JSON-serialized map. AKA DO NOT FUCK WITH

pass_flags_self

pass_flags that we are. If any of this matches a pass_flag on a moving thing, by default, we let them through.

rad_insulation

Radiation insulation types

receive_ricochet_chance_mod

When a projectile tries to ricochet off this atom, the projectile ricochet chance is multiplied by this

receive_ricochet_damage_coeff

When a projectile ricochets off this atom, it deals the normal damage * this modifier to this atom

should_spread_blood

Will the atom spread blood when touched?

simulated

Filter for actions - used by lighting overlays

smoothing_flags

Icon-smoothing behavior.

smoothing_groups

What smoothing groups does this atom belongs to, to match canSmoothWith. If null, nobody can smooth with it.

smoothing_junction

What directions this is currently smoothing with. IMPORTANT: This uses the smoothing direction flags as defined in icon_smoothing.dm, instead of the BYOND flags.

suit_fibers

List of fibers that this atom has

top_left_corner

Smoothing variable

top_right_corner

Smoothing variable

viewing_alternate_appearances

The alternate appearances we're viewing, stored here to reestablish them after Logout()s. Lazylist

Proc Details

AltClickNoInteract

Use this instead of [/mob/proc/AltClickOn] where you only want turf content listing without additional atom alt-click interaction

CanPathfindPass

This proc is used for telling whether something can pass by this atom in a given direction, for use by the pathfinding system.

Trying to generate one long path across the station will call this proc on every single object on every single tile that we're seeing if we can move through, likely multiple times per tile since we're likely checking if we can access said tile from multiple directions, so keep these as lightweight as possible.

For turfs this will only be used if pathing_pass_method is TURF_PATHING_PASS_PROC

Arguments:

• to_dir - What direction we're trying to move in, relevant for things like directional windows that only block movement in certain directions
• pass_info - Datum that stores info about the thing that's trying to pass us

IMPORTANT NOTE: /turf/proc/LinkBlockedWithAccess assumes that overrides of CanPathfindPass will always return true if density is FALSE If this is NOT you, ensure you edit your can_pathfind_pass variable. Check __DEFINES/path.dm

Topic

Passes Stat Browser Panel clicks to the game and calls client click on an atom

acid_act

Respond to acid being used on our atom

Default behaviour is to send COMSIG_ATOM_ACID_ACT and return

after_slip

Base proc, intended to be overriden.

This should only be called from one place: inside the slippery component. Called after a human mob slips on this atom.

If you want the person who slipped to have something special done to them, put it here.

bitmask_smooth

Basic smoothing proc. The atom checks for adjacent directions to smooth with and changes the icon_state based on that.

Returns the previous smoothing_junction state so the previous state can be compared with the new one after the proc ends, and see the changes, if any.

Objects override this to prevent unanchored objects from smoothing, see /obj/bitmask_smooth()

calculate_adjacencies

Scans all adjacent turfs to find targets to smooth with.

clean_radiation

Removes some radiation from an atom

Removes a configurable amount of radiation from an atom and stops green glow if radiation gets low enough through it. Arguments:

• clean_factor - How much radiation to remove, as a multiple of RAD_BACKGROUND_RADIATION (currently 9)

contents_ui_distance

public

Check the distance for a living mob. Really only used for checks outside the context of a mob. Otherwise, use shared_living_ui_distance().

required src_object The object which owns the UI. required user mob The mob who opened/is using the UI.

return UI_state The state of the UI.

defile

Begin defile and malfunction on-atom definitions

emag_act

This is when an atom is emagged. Should return false if it fails, or it has no emag_act defined.

emp_act

Proc which will make the atom act accordingly to an EMP. This proc can sleep depending on the implementation. So assume it sleeps!

severity - The severity of the EMP. Either EMP_HEAVY, EMP_LIGHT, or EMP_WEAKENED

examine_more

Extended description of an object. Allows you to double examine objects and have them give you a second description of an item. Useful for writing flavourful stuff.

find_type_in_direction

Scans direction to find targets to smooth with.

get_orbiters

Simple helper proc to get a list of everything directly orbiting the current atom, without checking contents, or null if nothing is.

get_orbiters_recursive

Recursive getter method to return a list of all ghosts transitively orbiting this atom. This will find orbiters either directly orbiting the followed atom, or any orbiters orbiting them (and so on).

This shouldn't be passed arugments.

get_orbiters_up_hierarchy

Check every object in the hierarchy above ourselves for orbiters, and return the full list of them. If an object is being held in a backpack, returns orbiters of the backpack, the person If recursive == TRUE, this will also check recursively through any ghosts seen to make sure we find everything upstream

get_runechat_color

Proc to allow atoms to set their own runechat colour

This is a proc designed to be overridden in places if you want a specific atom to use a specific runechat colour Exampls include consoles using a colour based on their screen colour, and mobs using a colour based off of a customisation property

hit_by_thrown_mob

This proc applies special effects of a carbon mob hitting something, be it a wall, structure, or window. You can set mob_hurt to false to avoid double dipping through subtypes if returning ..()

is_drainable

Is this atom drainable of reagents

is_drawable

Can we draw from this atom with an injectable atom

is_injectable

Is this atom injectable into other atoms

is_open_container

Convenience proc to see if a container is open for chemistry handling

is_refillable

Can this atoms reagents be refilled

mech_melee_attack

Handle melee attack by a mech

persistent_load

Atom Persistent Loader

Overridden on every atom which needs to load persistent data

persistent_save

Atom Persistent Saver

Overridden on every atom which needs to save persistent data

rad_act

Respond to a radioactive wave hitting this atom

Default behaviour is to send COMSIG_ATOM_RAD_ACT and return

ray_filter_helper

Used to create rays on an item. Make sure to removefilter("rays") when done with it

relaydrive

A special case of relaymove() in which the person relaying the move may be "driving" this atom

This is a special case for vehicles and ridden animals where the relayed movement may be handled by the riding component attached to this atom. Returns TRUE as long as there's nothing blocking the movement, or FALSE if the signal gets a reply that specifically blocks the movement

remove_orbiter

Remove an orbiter from the atom it's orbiting.

rename_interactive

• Call this when you want to present a renaming prompt to the user.

  It's a simple proc, but handles annoying edge cases such as forgetting to add a "cancel" button, or being able to rename stuff remotely.

  Arguments:

  • user - the renamer.
  • implement - the tool doing the renaming (usually, a pen).
  • use_prefix - whether the new name should follow the format of "thing - user-given label" or if we allow to change the name completely arbitrarily.
  • actually_rename - whether we want to really change the src.name, or if we want to do everything except that.
  • prompt - a custom "what do you want rename this thing to be?" prompt shown in the inpit box.

  Returns: Either null if the renaming was aborted, or the user-provided sanitized string.

return_analyzable_air

Return the air if we can analyze it

set_smoothed_icon_state

Changes the icon state based on the new junction bitmask. Returns the old junction value.

shuttleRotate

Base proc

storage_depth

Returns the storage depth of an atom up to the area level.

The storage depth is the number of storage items the atom is contained in. Returns -1 if the atom was not found in a container.

storage_depth_turf

Like /atom/proc/storage_depth, but returns the depth to the nearest turf.

Returns -1 if there's no top level turf. (A loc was null somewhere, or a non-turf atom's loc was an area somehow.)

tool_act

If it returns TRUE, attack chain stops

update_appearance

Updates the appearence of the icon

Mostly delegates to update_name, update_desc, and update_icon

Arguments:

• updates: A set of bitflags dictating what should be updated. Defaults to [ALL]

update_desc

Updates the description of the atom

update_icon

Updates the icon of the atom

update_icon_state

Updates the icon state of the atom

update_name

Updates the name of the atom

update_overlays

Updates the overlays of the atom. It has to return a list of overlays if it can't call the parent to create one. The list can contain anything that would be valid for the add_overlay proc: Images, mutable appearances, icon states...

zap_act

Respond to an electric bolt action on our item

Default behaviour is to return, we define here to allow for cleaner code later on
