Failsafe

Failsafe

Pretty much pokes the MC to make sure it's still alive.

Master

StonedMC

Designed to properly split up a given tick among subsystems Note: if you read parts of this code and think "why is it doing it that way" Odds are, there is a reason

SSambience

The subsystem used to play ambience to users every now and then, makes them real excited.

SScleanup

Cleanup Subsystem

For now, all it does is periodically clean the supplied global lists of any null values they may contain.

Why is this important?

Sometimes, these lists can gain nulls due to errors. For example, when a dead player trasitions from the dead_mob_list to the alive_mob_list, a null value may get stuck in the dead mob list. This can cause issues when other code tries to do things with the values in the list, but are instead met with null values. These problems are incredibly hard to track down and fix, so this subsystem is a solution to that.

SSpersistent_data

Persistent Data Subsystem

Provides a centralised handler for persistent data reading and writing. The subsystem does not do any actual spawning itself, as this focuses on objects and mobs Should anything that is turf persistence related added in, that can be chucked into this SS Its quite a simple subsystem. For now, anyways.

SSrunechat

Runechat Subsystem

Maintains a timer-like system to handle destruction of runechat messages. Much of this code is modeled after or adapted from the timer subsystem. Made by Bobbahbrown of /tg/station13

Note that this has the same structure for storing and queueing messages as the timer subsystem does for handling timers: the bucket_list is a list of chatmessage datums, each of which are the head of a circularly linked list. Any given index in bucket_list could be null, representing an empty bucket.

AA Note: One of the primary reasons for this is because each chatmessage has a timer attached to it, which is extra load on the GC At 150 population, the GC literally cannot keep up with processing 368,000 runechats and 368,000 extra timers in a 1 hour 30 minute round This also makes performance profiling a lot easier.

SStgui

tgui subsystem

Contains all tgui state and subsystem code.

SStimer

Timer Subsystem

Handles creation, callbacks, and destruction of timed events.

It is important to understand the buckets used in the timer subsystem are just a series of doubly-linked lists. The object at a given index in bucket_list is a /datum/timedevent, the head of a list, which has prev and next references for the respective elements in that bucket's list.

SSverb_manager

SSverb_manager, a subsystem that runs every tick and runs through its entire queue without yielding like SSinput. this exists because of how the byond tick works and where user inputted verbs are put within it.

see TICK_ORDER.md for more info on how the byond tick is structured.

The way the MC allots its time is via TICK_LIMIT_RUNNING, it simply subtracts the cost of SendMaps (MAPTICK_LAST_INTERNAL_TICK_USAGE) plus TICK_BYOND_RESERVE from the tick and uses up to that amount of time (minus the percentage of the tick used by the time it executes subsystems) on subsystems running cool things like atmospherics or Life or SSInput or whatever.

Without this subsystem, verbs are likely to cause overtime if the MC uses all of the time it has alloted for itself in the tick, and SendMaps uses as much as its expected to, and an expensive verb ends up executing that tick. This is because the MC is completely blind to the cost of verbs, it can't account for it at all. The only chance for verbs to not cause overtime in a tick where the MC used as much of the tick as it alloted itself and where SendMaps costed as much as it was expected to is if the verb(s) take less than TICK_BYOND_RESERVE percent of the tick, which isnt much. Not to mention if SendMaps takes more than 30% of the tick and the MC forces itself to take at least 70% of the normal tick duration which causes ticks to naturally overrun even in the absence of verbs.

With this subsystem, the MC can account for the cost of verbs and thus stop major overruns of ticks. This means that the most important subsystems like SSinput can start at the same time they were supposed to, leading to a smoother experience for the player since ticks arent riddled with minor hangs over and over again.

Proc Details

HTTPGet

HTTP Get (Powered by RUSTG)

This proc should be used as a replacement for [world.Export()] due to an underlying issue with it. See: https://www.byond.com/forum/post/2772166 The one thing you will need to be aware of is that this no longer wraps the response inside a "file", so anything that relies on a file2text() unwrap will need tweaking. RUST HTTP also has better support for HTTPS as well as weird quirks with modern webservers. Returns an assoc list that follows the standard [world.Export()] format (https://secure.byond.com/docs/ref/index.html#/world/proc/Export), with the above exception

Arguments:

• url - URL to GET

HeapPathWeightCompare

TODO: Macro this to reduce proc overhead

returns TRUE if the queuing was successful, FALSE otherwise.

add_attack_logs

Creates attack (old and new) logs for the user and defense logs for the target. Will message admins depending on the custom_level, user and target.

emissive_appearance

Produces a mutable appearance glued to the EMISSIVE_PLANE dyed to be the EMISSIVE_COLOR. Order of application matters: Default generated blockers are overlays, and will block its own emissive underlays. If you want an object to be both a blocker, and have their own emissive, it has to be an overlay instead. Grayscale lightmasks are visible in the BYOND right-click and Examine pane, unless they're covered up by another overlay.

emissive_blocker

Arguments:

• M - the mob you're checking

get_antag_type_truncated_plaintext_string

A proc that return a string containing all the singled out antags . Empty string if not antag

Usually, you'd return a FALSE, but since this is consumed by javascript you're in for a world of hurt if you pass a byond FALSE which get converted into a fucking string anyway and pass for TRUE in check. Fuck. It always append "(May be other antag)" Arguments:

• M - the mob you're checking

get_atoms_of_type

Returns a list of atoms in a location of a given type. Can be refined to look for pixel-shift.

Arguments:

get_living_players

This proc returns every player with a client who is not a ghost or a new_player

get_path_to

This file contains the stuff you need for using JPS (Jump Point Search) pathing, an alternative to A* that skips over large numbers of uninteresting tiles resulting in much quicker pathfinding solutions.

This is the proc you use whenever you want to have pathfinding more complex than "try stepping towards the thing". If no path was found, returns an empty list, which is important for bots like medibots who expect an empty list rather than nothing.

Arguments:

• caller: The movable atom that's trying to find the path
• end: What we're trying to path to. It doesn't matter if this is a turf or some other atom, we're gonna just path to the turf it's on anyway
• max_distance: The maximum number of steps we can take in a given path to search (default: 30, 0 = infinite)
• mintargetdistance: Minimum distance to the target before path returns, could be used to get near a target, but not right to it - for an AI mob with a gun, for example.
• id: An ID card representing what access we have and what doors we can open. Its location relative to the pathing atom is irrelevant
• simulated_only: Whether we consider turfs without atmos simulation (AKA do we want to ignore space)
• exclude: If we want to avoid a specific turf, like if we're a mulebot who already got blocked by some turf
• skip_first: Whether or not to delete the first item in the path. This would be done because the first item is the starting tile, which can break movement for some creatures.
• diagonal_safety: ensures diagonal moves won't use invalid midstep turfs by splitting them into two orthogonal moves if necessary

get_rad_contents

A special GetAllContents that doesn't search past things with rad insulation Components which return COMPONENT_BLOCK_RADIATION prevent further searching into that object's contents. The object itself will get returned still. The ignore list makes those objects never return at all

get_valid_vent_spawns

Returns a list of vents that can be used as a potential spawn if they meet the criteria set by the arguments

Will not include parent-less vents to the returned list. Arguments:

• unwelded_only - Whether the list should only include vents that are unwelded
• exclude_mobs_nearby - Whether to exclude vents that are near living mobs
• min_network_size - The minimum length (non-inclusive) of the vent's parent network. A smaller number means vents in small networks (Security, Virology) will appear in the list

getline

Gets the turfs which are between the two given atoms. Including their positions Only works for atoms on the same Z level which is not 0. So an atom located in a non turf won't work Arguments:

• M - The source atom
• N - The target atom

goonchem_vortex

Throws or pulls objects to/from a chem reaction

Scales the amount of objects thrown with the volume, unless ignore_volume is TRUE

Arguments:

• T - The turf to use as the throw from/to point
• pull - Do we want to pull objects towards T (TRUE) or push them away from it (FALSE)
• volume - The volume of reagents. Used to scale the effect is ignore_volume = FALSE
• ignore_volume - Do we want to ignore the volume of reagents and just throw regardless

icon_exists

Checks if the given iconstate exists in the given file, caching the result. Setting no_sprite to TRUE will print a stack trace ONCE.

is_bad_connection

Connection checker

Checks the connection frequency against the intended frequency for the message NOTE: I barely know what on earth this does, but it works and it scares me Arguments:

• old_freq - Frequency of the connection
• new_freq - Frequency of the message

is_special_character

ADMIN HELPER PROCS A proc that return whether the mob is a "Special Character" aka Antagonist

Arguments:

• M - the mob you're checking

is_type_in_UID_list

If the list L contains a datum UID who's type matches D's type, returns the UID of that datum in the list. Otherwise returns null.

locateUID

Locates a datum based off of the UID

Replacement for locate() which takes a UID instead of a ref Returns the datum, if found

makeDatumRefLists

Initial Building

make_associative

A proc for turning a list into an associative list.

A simple proc for turning all things in a list into an associative list, instead Each item in the list will have an associative value of TRUE

Arguments:

• flat_list - the list that it passes to make associative

message_adminTicket

Sends a message to the staff able to see admin tickets Arguments: msg - The message being send important - If the message is important. If TRUE it will ignore the CHAT_NO_TICKETLOGS preferences, send a sound and flash the window. Defaults to FALSE

message_mentorTicket

Sends a message to the staff able to see mentor tickets Arguments: msg - The message being send important - If the message is important. If TRUE it will ignore the CHAT_NO_TICKETLOGS preferences, send a sound and flash the window. Defaults to FALSE

pick_multiple_unique

Picks multiple unique elements from the suplied list. If the given list has a length less than the amount given then it will return a list with an equal amount

Arguments:

• listfrom - The list where to pick from
• amount - The amount of elements it tries to pick.

random_body_accessory

Returns a random body accessory for a given species name. Can be null based on is_optional argument.

Arguments:

• species - The name of the species to filter valid body accessories.
• is_optional - Whether no body accessory (null) is an option.

recover_all_SS_and_recreate_master

Recreate all SSs which will still cause data survive due to Recover(), the new Master will then find and take them from global.vars

rustg_get_version

Gets the version of rust_g

safe_get_ckey

Safe ckey getter

Should be used whenever broadcasting public information about a mob, as this proc will make a best effort to hide the users ckey if they request it. It will first check the mob for a client, then use the mobs last ckey as a directory lookup. If a client cant be found to check preferences on, it will just show as DC'd. This proc should only be used for public facing stuff, not administration related things.

Arguments:

• M - Mob to get a safe ckey of

seedify

This proc could probably be scoped better, also it's logic is cursed and hard to understand

setupcult

.

shake_camera

Shake the camera of the person viewing the mob SO REAL!

show_blurb

Shows a ticker reading out the given text on a client's screen.

targets = mob or list of mobs to show it to. duration = how long it lingers after it finishes ticking. message = the message to display. Due to using maptext it isn't very flexible format-wise. 11px font, up to 480 pixels per line. Use \n for line breaks. Single-character HTML tags (, , etc.) are handled correctly but others display strangely. Note that maptext can display text macros in strange ways, ex. \improper showing as "ÿ". Lines containing only spaces, including ones only containing "\improper ", don't display. scroll_down = by default each line pushes the previous line upwards - this tells it to start high and scroll down. Ticks on \n - does not autodetect line breaks in long strings. screen_position = screen loc for the bottom-left corner of the blurb. text_alignment = "right", "left", or "center" text_color = colour of the text. blurb_key = a key used for specific blurb types so they are not shown repeatedly. ignore_key = used to skip key checks. text_limit = limit in characters of the message.
