top_left_corner

Smoothing variable

top_right_corner

update_on_z

Lazylist of all images (or atoms, I'm sorry) (hopefully attached to us) to update when we change z levels You will need to manage adding/removing from this yourself, but I'll do the updating for you

update_overlays_on_z

Lazylist of all overlays attached to us to update when we change z levels You will need to manage adding/removing from this yourself, but I'll do the updating for you Oh and note, if order of addition is important this WILL break that. so mind yourself

uses_integrity

any atom that uses integrity and can be damaged must set this to true, otherwise the integrity procs will throw an error

Proc Details

AllowDrop

Are you allowed to drop this atom

Beam

This is what you use to start a beam. Example: origin.Beam(target, args). Store the return of this proc if you don't set maxdist or time, you need it to delete the beam.

Unless you're making a custom beam effect (see the beam_type argument), you won't actually have to mess with any other procs. Make sure you store the return of this Proc, you'll need it to kill the beam. Arguments: BeamTarget: Where you're beaming from. Where do you get origin? You didn't read the docs, fuck you. icon_state: What the beam's icon_state is. The datum effect isn't the ebeam object, it doesn't hold any icon and isn't type dependent. icon: What the beam's icon file is. Don't change this, man. All beam icons should be in beam.dmi anyways. maxdistance: how far the beam will go before stopping itself. Used mainly for two things: preventing lag if the beam may go in that direction and setting a range to abilities that use beams. beam_type: The type of your custom beam. This is for adding other wacky stuff for your beam only. Most likely, you won't (and shouldn't) change it.

CanAStarPass

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 CanAStarPass will always return true if density is FALSE If this is NOT you, ensure you edit your can_astar_pass variable. Check __DEFINES/path.dm

CanAllowThrough

Returns true or false to allow the mover to move through src

CanPass

Whether the mover object can avoid being blocked by this atom, while arriving from (or leaving through) the border_dir.

CanReach

A backwards depth-limited breadth-first-search to see if the target is logically "in" anything adjacent to us.

CheckParts

Ensure a list of atoms/reagents exists inside this atom

Goes throught he list of passed in parts, if they're reagents, adds them to our reagent holder creating the reagent holder if it exists.

If the part is a moveable atom and the previous location of the item was a mob/living, it calls the inventory handler transferItemToLoc for that mob/living and transfers the part to this atom

Otherwise it simply forceMoves the atom into this atom

Click

Before anything else, defer these calls to a per-mobtype handler. This allows us to remove istype() spaghetti code, but requires the addition of other handler procs to simplify it.

Alternately, you could hardcode every mob's variation in a flat /mob/proc/ClickOn proc; however, that's a lot of code duplication and is hard to maintain.

Note that this proc can be overridden, and is in the case of screen objects.

Destroy

Top level of the destroy chain for most atoms

Cleans up the following:

• Removes alternate apperances from huds that see them
• qdels the reagent holder from atoms if it exists
• clears the orbiters list
• clears overlays and priority overlays
• clears the light object

Entered

An atom has entered this atom's contents

Default behaviour is to send the COMSIG_ATOM_ENTERED

Exit

An atom is attempting to exit this atom's contents

Default behaviour is to send the COMSIG_ATOM_EXIT

Exited

An atom has exited this atom's contents

Default behaviour is to send the COMSIG_ATOM_EXITED

GetMergeGroup

Gets a merger datum representing the connected blob of objects in the allowed_types argument

HasProximity

Is this atom within 1 tile of another atom

Initialize

The primary method that objects are setup in SS13 with

we don't use New as we have better control over when this is called and we can choose to delay calls or hook other logic in and so forth

During roundstart map parsing, atoms are queued for initialization in the base atom/New(), After the map has loaded, then Initialize is called on all atoms one by one. NB: this is also true for loading map templates as well, so they don't Initialize until all objects in the map file are parsed and present in the world

If you're creating an object at any point after SSInit has run then this proc will be immediately be called from New.

mapload: This parameter is true if the atom being loaded is either being initialized during the Atom subsystem initialization, or if the atom is being loaded from the map template. If the item is being created at runtime any time after the Atom subsystem is initialized then it's false.

The mapload argument occupies the same position as loc when Initialize() is called by New(). loc will no longer be needed after it passed New(), and thus it is being overwritten with mapload at the end of atom/New() before this proc (atom/Initialize()) is called.

You must always call the parent of this proc, otherwise failures will occur as the item will not be seen as initialized (this can lead to all sorts of strange behaviour, like the item being completely unclickable)

You must not sleep in this proc, or any subprocs

Any parameters from new are passed through (excluding loc), naturally if you're loading from a map there are no other arguments

Must return an initialization hint or a runtime will occur.

Note: the following functions don't call the base for optimization and must copypasta handling:

• /turf/proc/Initialize
• /turf/open/space/proc/Initialize

IsObscured

Is the atom obscured by a PREVENT_CLICK_UNDER_1 object above it

LateInitialize

Late Initialization, for code that should run after all atoms have run Initialization

To have your LateIntialize proc be called, your atoms Initialization proc must return the hint INITIALIZE_HINT_LATELOAD otherwise it will never be called.

useful for doing things like finding other machines on GLOB.machines because you can guarantee that all atoms will actually exist in the "WORLD" at this time and that all their Initialization code has been run

New

Called when an atom is created in byond (built in engine proc)

Not a lot happens here in SS13 code, as we offload most of the work to the Initialization proc, mostly we run the preloader if the preloader is being used and then call InitAtom of which the ultimate result is that the Initialize proc is called.

RemoveInvisibility

Removes the specified invisibility source from the tracker

SetInvisibility

Sets invisibility according to priority. If you want to be able to undo the value you set back to what it would be otherwise, you should provide an id here and remove it using RemoveInvisibility(id)

Shake

Perform a shake on an atom, resets its position afterwards

ShowProcessingGui

Creates the radial and processes the selected option

SpinAnimation

Proc called when you want the atom to spin around the center of its icon (or where it would be if its transform var is translated) By default, it makes the atom spin forever and ever at a speed of 60 rpm.

Arguments:

• speed: how much it takes for the atom to complete one 360° rotation
• loops: how many times do we want the atom to rotate
• clockwise: whether the atom ought to spin clockwise or counter-clockwise
• segments: in how many animate calls the rotation is split. Probably unnecessary, but you shouldn't set it lower than 3 anyway.
• parallel: whether the animation calls have the ANIMATION_PARALLEL flag, necessary for it to run alongside concurrent animations.

add_blood_DNA

Adds blood dna to the atom

add_context

Creates a "Type-B" contextual screentip interaction. When a user hovers over this, this proc will be called in order to provide context for contextual screentips. You must call register_context() in order for this to be registered. A screentip context list is a list that has context keys (SCREENTIP_CONTEXT_*, from __DEFINES/screentips.dm) that map to the action as text. If you mutate the list in this signal, you must return CONTEXTUAL_SCREENTIP_SET. source can, in all cases, be replaced with src, and only exists because this proc directly connects to a signal.

add_fiber_list

Add a list of fibers to the atom

add_fibers

Adds a single fiber to the atom

add_fingerprint

base_ranged_item_interaction

Ranged item interaction

Handles non-combat ranged interactions of a tool on this atom, such as shooting a gun in the direction of someone*, having a scanner you can point at someone to scan them at any distance, or pointing a laser pointer at something.

*While this intuitively sounds combat related, it is not, because a "combat use" of a gun is gun-butting.

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.

A cut-out proc for /atom/proc/bullet_act so living mobs can have their own armor behavior checks without causing issues with needing their own on_hit call

click_alt

Custom alt click interaction

Override this to change default alt click behavior. Return CLICK_ACTION_SUCCESS, CLICK_ACTION_BLOCKING or NONE.

Guard clauses

Consider adding interaction_flags_click before adding unique guard clauses.

Return flags

Forgetting your return will cause the default alt click behavior to occur thereafter.

The difference between NONE and BLOCKING can get hazy, but I like to keep NONE limited to guard clauses and "never" cases.

A good usage for BLOCKING over NONE is when it's situational for the item and there's some feedback indicating this.

Examples:

User is a ghost, alt clicks on item with special disk eject: NONE

Machine broken, no feedback: NONE

Alt click a pipe to max output but its already max: BLOCKING

Alt click a gun that normally works, but is out of ammo: BLOCKING

User unauthorized, machine beeps: BLOCKING

@param {mob} user - The person doing the alt clicking.

click_alt_secondary

Custom alt click secondary interaction

Override this to change default alt right click behavior.

Guard clauses

Consider adding interaction_flags_click before adding unique guard clauses.

click_ctrl

Custom ctrl click interaction

Override this to change default ctrl click behavior. Return CLICK_ACTION_SUCCESS, CLICK_ACTION_BLOCKING or NONE.

Guard clauses

Consider adding interaction_flags_click before adding unique guard clauses.

Return flags

Forgetting your return will cause the default ctrl click behavior to occur thereafter.

Returning any value besides NONE will stop the attack chain and thus stop the object from getting pulled/grabbed

click_ctrl_shift

Custom ctrl shift click interaction

Guard clauses

Consider adding interaction_flags_click before adding unique guard clauses.

• obj/item/card/emag/emag_card: The emag that was used. Nullable.

Returns: TRUE if the emag had any effect, falsey otherwise.

emp_act

React to an EMP of the given severity

Default behaviour is to send the COMSIG_ATOM_PRE_EMP_ACT and COMSIG_ATOM_EMP_ACT signal

If the pre-signal does not return protection, and there are attached wires then we call emp_pulse on the wires

We then return the protection value

ex_act

React to being hit by an explosion

Should be called through the EX_ACT wrapper macro. The wrapper takes care of the COMSIG_ATOM_EX_ACT signal. as well as calling /atom/proc/contents_explosion.

Returns TRUE by default, and behavior should be implemented on children procs on a per-atom basis. Should only return FALSE if we resist the explosion for any reason. We assume that the default is TRUE because all atoms should be considered destructible in some manner unless they explicitly opt out (in our current framework). However, the return value itself doesn't have any external consumers, it's only so children procs can listen to the value from their parent procs (due to the nature of the EX_ACT macro). Thus, the return value only matters on overrides of this proc, and the only thing that truly matters is the code that is executed (applying damage, calling damage procs, etc.)

examine

Called when a mob examines this atom: /mob/verb/examinate

Default behaviour is to get the name and icon of the object and its reagents where the [TRANSPARENT] flag is set on the reagents holder

Produces a signal COMSIG_ATOM_EXAMINE, for modifying the list returned from this proc

examine_descriptor

What this atom should be called in examine tags

examine_more

Called when a mob examines (shift click or verb) this atom twice (or more) within EXAMINE_MORE_WINDOW (default 1 second)

This is where you can put extra information on something that may be superfluous or not important in critical gameplay moments, while allowing people to manually double-examine to take a closer look

Produces a signal COMSIG_ATOM_EXAMINE_MORE

examine_post_descriptor

Returns a list of strings to be displayed after the descriptor

examine_tags

A list of "tags" displayed after atom's description in examine. This should return an assoc list of tags -> tooltips for them. If item is null, then no tooltip is assigned.

• TGUI tooltips (not the main text) in chat cannot use HTML stuff at all, so trying something like <b><big>ffff</big></b> will not work for tooltips.

For example:

. = list()
.["small"] = "It is a small item."
.["fireproof"] = "It is made of fire-retardant materials."
.["and conductive"] = "It's made of conductive materials and whatnot. Blah blah blah." // having "and " in the end tag's main text/key works too!

will result in

It is a small, fireproof and conductive item.

where "item" is pulled from /atom/proc/examine_descriptor

examine_title

Formats the atom's name into a string for use in examine (as the "title" of the atom)

• user - the mob examining the atom

get_all_contents_type

identical to get_all_contents but returns a list of atoms of the type passed in the argument.

get_all_orbiters

Recursive getter method to return a list of all ghosts orbitting this atom

This will work fine without manually passing arguments.

• processed - The list of atoms we've already convered
• source - Is this the atom for who we're counting up all the orbiters?
• ignored_stealthed_admins - If TRUE, don't count admins who are stealthmoded and orbiting this

get_examine_name

Get the name of this object for examine

You can override what is returned from this proc by registering to listen for the COMSIG_ATOM_GET_EXAMINE_NAME signal

get_id_examine_strings

Returns an extended list of examine strings for any contained ID cards.

Arguments:

• user - The user who is doing the examining.

get_master_material

Gets the most common material in the object.

get_material_composition

get_material_english_list

Returns a string like "plasma, paper and glass" from a list of materials

For example, we can have items made of two different materials, with the primary contributing a good 1.2 multiplier and the second a meager 0.3.

The GET_MATERIAL_MODIFIER macro will handles some modifications where the minimum should be 1 if above 1 and the maximum be 1 if below 1. Just don't return negative values.

get_save_vars

Map exporter Inputting a list of turfs into convert_map_to_tgm() will output a string with the turfs and their objects / areas on said turf into the TGM mapping format for .dmm files. This file can then be opened in the map editor or imported back into the game.

This has been made semi-modular so you should be able to use these functions elsewhere in code if you ever need to get a file in the .dmm format

get_visible_name

Used by mobs to determine the name for someone wearing a mask, or with a disfigured or missing face. By default just returns the atom's name. add_id_name will control whether or not we append "(as [id_name])". force_real_name will always return real_name and add (as face_name/id_name) if it doesn't match their appearance

handle_basic_attack

Returns true if this atom has gravity for the passed in turf

Sends signals COMSIG_ATOM_HAS_GRAVITY and COMSIG_TURF_HAS_GRAVITY, both can force gravity with the forced gravity var.

micro-optimized to hell because this proc is very hot, being called several times per movement every movement.

HEY JACKASS, LISTEN IF YOU ADD SOMETHING TO THIS PROC, MAKE SURE /mob/living ACCOUNTS FOR IT Living mobs treat gravity in an event based manner. We've decomposed this proc into different checks for them to use. If you add more to it, make sure you do that, or things will behave strangely

Gravity situations:

• No gravity if you're not in a turf
• No gravity if this atom is in is a space turf
• Gravity if the area it's in always has gravity
• Gravity if there's a gravity generator on the z level

Arguments:

• required_material: The type of material we are checking for
• mat_amount: The minimum required amount of material

hitby

React to being hit by a thrown object

Default behaviour is to call hitby_react on ourselves after 2 seconds if we are dense and under normal gravity.

Im not sure why this the case, maybe to prevent lots of hitby's if the thrown object is deleted shortly after hitting something (during explosions or other massive events that throw lots of items around - singularity being a notable example)

Worth of note: If hitby returns TRUE, it means the object has been blocked or catched by src. So far, this is only possible for living mobs and carbons, who can hold shields and catch thrown items.

register_context

Create a "Type-B" contextual screentip interaction, registering to add_context(). This will run add_context() when the atom is hovered over by an item for context. add_context() will not be called unless this is run.

set every hud image in the given category active so other people with the given hud can see it. Arguments:

• hud_category - the index in our active_hud_list corresponding to an image now being shown.
• update_huds - if FALSE we will just put the hud_category into active_hud_list without actually updating the atom_hud datums subscribed to it
• exclusive_hud - if given a reference to an atom_hud, will just update that hud instead of all global ones attached to that category. This is because some atom_hud subtypes arent supposed to work via global categories, updating normally would affect all of these which we dont want.

For enabling and disabling material effects from an item (mainly VV)

tool_act

Tool Act

Handles using specific tools on this atom directly. Only called when combat mode is off.

Handles the tool_acts in particular, such as wrenches and screwdrivers.

This can be overridden to handle unique "tool interactions" IE using an item like a tool (when it's not actually one) This is particularly useful for things that shouldn't be inserted into storage (because tool acting runs before storage checks) but otherwise does nothing that [item_interaction] doesn't already do.

In other words, use sparingly. It's harder to use (correctly) than [item_interaction].

transfer_mob_blood_dna

to add a mob's dna info into an object's blood_dna list.

undebug

Disables light debugging, so you can let a scene fall to what it visually should be, or just fix admin fuckups

Checks if this atom uses the GAGS system and if so updates the icon

update_icon

Updates the icon of the atom

update_icon_state

Updates the icon state of the atom

update_inhand_icon

Checks the atom's loc and calls update_held_items on it if it is a mob.

This should only be used in situations when you are unable to use /datum/element/update_icon_updates_onmob for whatever reason. Check code/datums/elements/update_icon_updates_onmob.dm before using this. Adding that to the atom and calling update_appearance will work for most cases.

Arguments:

• mob/target - The mob to update the icons of. Optional argument, use if the atom's loc is not the mob you want to update.

update_integrity

Handles the integrity of an atom changing. This must be called instead of changing integrity directly.

update_name

Updates the name of the atom

update_overlays

Updates the overlays of the atom

vv_edit_var

call back when a var is edited on this atom

Can be used to implement special handling of vars

At the atom level, if you edit a var named "color" it will add the atom colour with admin level priority to the atom colours list

Also, if GLOB.Debug2 is FALSE, it sets the ADMIN_SPAWNED_1 flag on flags_1, which signifies the object has been admin edited

vv_get_dropdown

Return the markup to for the dropdown list for the VV panel for this atom

Override in subtypes to add custom VV handling in the VV panel
