Proc Details

AllowDrop

Are you allowed to drop this atom

AltClickNoInteract

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

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

CanMoveOnto

A version of CanPass() that accounts for vertical movement.

CanPass

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

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

CheckReachableAdjacency

Checks if a reacher is adjacent to us.

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

Default behaviour is to send the COMSIG_ATOM_ENTERED

Exit

Default behaviour is to send the COMSIG_ATOM_EXIT

Exited

Default behaviour is to send the COMSIG_ATOM_EXITED

GetExplosionBlock

returns how much the object blocks an explosion. Used by subtypes.

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 intialization in the base atom/New(), After the map has loaded, then Initalize is called on all atoms one by one. NB: this is also true for loading map templates as well, so they don't Initalize 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 intialized during the Atom subsystem intialization, 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 intialized 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 initalized (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

IsContainedAtomAccessible

Returns TRUE if an atom contained within our contents is reachable.

IsObscured

Is the atom obscured by a PREVENT_CLICK_UNDER_1 object above it

IsReachableBy

Returns TRUE if a movable can "Reach" this atom. This is defined as adjacency

This is used for crafting by hitting the floor with items. The inital use case is glass sheets breaking in to shards when the floor is hit. Args:

• user: The movable trying to reach us.
• reacher_range: How far the reacher can reach.
• depth: How deep nested inside of an atom contents stack an object can be.
• direct_access: Do not override. Used for recursion.

LateInitialize

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

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

useful for doing things like finding other machines using INSTANCES_OF() because you can guarantee that all atoms will actually exist in the "WORLD" at this time and that all their Intialization 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 Intialization proc, mostly we run the preloader if the preloader is being used and then call InitAtom of which the ultimate result is that the Intialize proc is called.

Returns TRUE if new blood dna was added.

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

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.

set_hud_image_inactive
