## About The Pull Request
Ultrakill is a neat game that I like, and I like to add fun things from
things I like. This PR adds the marksman revolver as an admin-only
weapon, complete with coin flipping and splitshotting mechanics! [Have a
video demonstration!](https://streamable.com/5x4mnj)
Basically, right clicking on a visible tile flips a coin towards a
random adjacent tile to the one you targeted. Shooting the coin
projectile with the hitscan primary fire while it's within one tile of
the target will trigger a splitshot. Those two child splitshots will
roughly follow the priority order of Ultrakill (prioritizing coins [for
even more splits!], then nearby mobs, then less nearby mobs, then other
random stuff nearby). I plan to add other stuff for the shots to
prioritize like fuel tanks, windows, and others.
I'm still working out some of the finer details of balance and more
closely matching how it works to UK (while still working in the realm of
SS13), and of course I hope to get unique sprites/sounds/whatever.

About The Pull Request
I've reworked multiz. This was done because our current implementation of multiz flattens planes down into just the openspace plane. This breaks any effects we attach to plane masters (including lighting), but it also totally kills the SIDE_MAP map format, which we NEED for wallening (A major 3/4ths resprite of all wall and wall adjacent things, making them more then one tile high. Without sidemap we would be unable to display things both in from of and behind objects on map. Stupid.)
This required MASSIVE changes. Both to all uses of the plane var for reasons I'll discuss later, and to a ton of different systems that interact with rendering.
I'll do my best to keep this compact, but there's only so much I can do. Sorry brother.
Core idea
OK: first thing.
vis_contents as it works now squishes the planes of everything inside it down into the plane of the vis_loc.
This is bad. But how to do better?
It's trivially easy to make copies of our existing plane masters but offset, and relay them to the bottom of the plane above. Not a problem. The issue is how to get the actual atoms on the map to "land" on them properly.
We could use FLOAT_PLANE to offset planes based off how they're being seen, in theory this would allow us to create lens for how objects are viewed.
But that's not a stable thing to do, because properly "landing" a plane on a desired plane master would require taking into account every bit of how it's being seen, would inherently break this effect.
Ok so we need to manually edit planes based off "z layer" (IE: what layer of a z stack are you on).
That's the key conceit of this pr. Implementing the plane cube, and ensuring planes are always offset properly.
Everything else is just gravy.
About the Plane Cube
Each plane master (except ones that opt out) is copied down by some constant value equal to the max absolute change between the first and the last plane.
We do this based off the max z stack size detected by SSmapping. This is also where updates come from, and where all our updating logic will live.
As mentioned, plane masters can choose to opt out of being mirrored down. In this case, anything that interacts with them assuming that they'll be offset will instead just get back the valid plane value. This works for render targets too, since I had to work them into the system as well.
Plane masters can also be temporarily hidden from the client's screen. This is done as an attempt at optimization, and applies to anything used in niche cases, or planes only used if there's a z layer below you.
About Plane Master Groups
BYOND supports having different "maps" on screen at once (IE: groups of items/turfs/etc)
Plane masters cannot cover 2 maps at once, since their location is determined by their screen_loc.
So we need to maintain a mirror of each plane for every map we have open.
This was quite messy, so I've refactored it (and maps too) to be a bit more modular.
Rather then storing a list of plane masters, we store a list of plane master group datums.
Each datum is in charge of the plane masters for its particular map, both creating them, and managing them.
Like I mentioned, I also refactored map views. Adding a new mapview is now as simple as newing a /atom/movable/screen/map_view, calling generate_view with the appropriate map id, setting things you want to display in its vis_contents, and then calling display_to on it, passing in the mob to show ourselves to.
Much better then the hardcoded pattern we used to use. So much duplicated code man.
Oh and plane master controllers, that system we have that allows for applying filters to sets of plane masters? I've made it use lookups on plane master groups now, rather then hanging references to all impacted planes. This makes logic easier, and prevents the need to manage references and update the controllers.

In addition, I've added a debug ui for plane masters.
It allows you to view all of your own plane masters and short descriptions of what they do, alongside tools for editing them and their relays.
It ALSO supports editing someone elses plane masters, AND it supports (in a very fragile and incomplete manner) viewing literally through someone else's eyes, including their plane masters. This is very useful, because it means you can debug "hey my X is yorked" issues yourself, on live.
In order to accomplish this I have needed to add setters for an ungodly amount of visual impacting vars. Sight flags, eye, see_invis, see_in_dark, etc.
It also comes with an info dump about the ui, and plane masters/relays in general.
Sort of on that note. I've documented everything I know that's niche/useful about our visual effects and rendering system. My hope is this will serve to bring people up to speed on what can be done more quickly, alongside making my sin here less horrible.
See https://github.com/LemonInTheDark/tgstation/blob/multiz-hell/.github/guides/VISUALS.md.
"Landing" planes
Ok so I've explained the backend, but how do we actually land planes properly?
Most of the time this is really simple. When a plane var is set, we need to provide some spokesperson for the appearance's z level. We can use this to derive their z layer, and thus what offset to use.
This is just a lot of gruntwork, but it's occasionally more complex.
Sometimes we need to cache a list of z layer -> effect, and then use that.
Also a LOT of updating on z move. So much z move shit.
Oh. and in order to make byond darkness work properly, I needed to add SEE_BLACKNESS to all sight flags.
This draws darkness to plane 0, which means I'm able to relay it around and draw it on different z layers as is possible. fun darkness ripple effects incoming someday
I also need to update mob overlays on move.
I do this by realiizing their appearances, mutating their plane, and then readding the overlay in the correct order.
The cost of this is currently 3N. I'm convinced this could be improved, but I've not got to it yet.
It can also occasionally cause overlays to corrupt. This is fixed by laying a protective ward of overlays.Copy in the sand, but that spell makes the compiler confused, so I'll have to bully lummy about fixing it at some point.
Behavior changes
We've had to give up on the already broken gateway "see through" effect. Won't work without managing gateway plane masters or something stupid. Not worth it.
So instead we display the other side as a ui element. It's worse, but not that bad.
Because vis_contents no longer flattens planes (most of the time), some uses of it now have interesting behavior.
The main thing that comes to mind is alert popups that display mobs. They can impact the lighting plane.
I don't really care, but it should be fixable, I think, given elbow grease.
Ah and I've cleaned up layers and plane defines to make them a bit easier to read/reason about, at least I think.

* Alright, so I'm optimizing parallax code so I can justify making it do a
bit more work
To that end, lets make the checks it does each process event based.
There's two. One is for a difference in view, which is an easy fix since
I added a view setter like a year back now.
The second is something planets do when you change your z level.
This gets more complicated, because we're "owned" by a client.
So the only real pattern we can use to hook into the client's mob's
movement is something like connect_loc_behalf.
So, I've made connect_mob_behalf. Fuck you.
This saves a proc call and some redundant logic
* Fixes random parallax stuttering
Ok so this is kinda a weird one but hear me out.
Parallax has this concept of "direction" that some areas use, mostly
the shuttle transit ones. Set when you move into a new area.
So of course it has a setter. If you pass it a direction that it doesn't
already have, it'll start up the movement animation, and disable normal
parallax for a bit to give it some time to get going.
This var is typically set to 0.
The problem is we were setting /area/space's direction to null in
shuttle movement code, because of a forgotten proc arg.
Null is of course different then 0, so this would trigger a halt in
parallax processing.
This causes a lot of strange stutters in parallax, mostly when you're
moving between nearspace and space. It looks really bad, and I'm a bit
suprised none noticed.
I've fixed it, and added a default arg to the setter to prevent this
class of issue in future. Things look a good bit nicer this way
* Adds animation back to parallax
Ok so like, I know this was removed and "none could tell" and whatever,
and in fairness this animation method is a bit crummy.
What we really want to do is eliminate "halts" and "jumps" in the
parallax moveemnt. So it should be smooth.
As it is on live now, this just isn't what happens, you get jumping
between offsets. Looks frankly, horrible. Especially on the station.
Just what I've done won't be enough however, because what we need to do
is match our parallax scroll speed with our current glide speed. I need
to figure out how to do this well, and I have a feeling it will involve
some system of managing glide sources.
Anyway for now the animation looks really nice for ghosts with default
(high) settings, since they share the same delay.
I've done some refactoring to how old animation code worked pre (4b04f9012d). Two major
changes tho.
First, instead of doing all the animate checks each time we loop over a
layer, we only do the layer dependant ones. This saves a good bit of
time.
Second, we animate movement on absolute layers too. They're staying in
the same position, but they still move on the screen, so we do the same
gental leaning. This has a very nice visual effect.
Oh and I cleaned up some of the code slightly.
Removes the old sniper rifle zoom, replaces it with a scope component. the scope activates on right click and lets your camera follow your mouse.
https://streamable.com/2c63u4 (due to byond rounding some shots were weirdly missed in that video, its fixed now)
Also adds sniper marksman ammo to the nukie uplink. It does slightly less damage, but it is hitscan and has one guaranteed ricochet shot, so you can shoot a wall and it could still hit someone.
About The Pull Request
I have received exemption from the freeze by Oranges.
This PR was originally done for Skyrat-tg, as a bounty. Oranges took interest and Skyrat people approved taking it upstream so I did. (original PR Skyrat-SS13/Skyrat-tg#9912 )
Features:
This PR adds "field of view" mechanics, which by default don't do anything.
Once you pick up and wear a gas mask you'll notice a cone behind you.
That cone will hide all mobs, projectiles and projectile effects.
HOWEVER... hidden things in the cone (or for people who are blind or nearsighted) will play a visual effect.
The fov cone shadow density can be adjusted
Technicalities:
Originally a component, but by Watermelon's advice I have made this a datumized behaviour instead. (semi-component) This way it is faster, less memory use etc. Once again a component
People have native fov, which can be enabled by a config, by default it's off. (or by an admin verb)
People have fov traits, which add the fov impairings to you, gas masks do that now. All clothes have a support for possibly applying them.
Moves all things that should be hidden onto a new plane which is just above GAME_PLANE, that was we can efficiently filter them out of clients views.
Being dead or extending your eye view (xenobio console) will disable the FOV mask.
This PR was brought to you by Skyrat paying me aswell as rotational mathematics

Oranges approves so it's good.

This fixes Emitters, beam_rifle, and more.
The great rendering refactor (#61286) changed how rendering worked.
Entities need to have a usable plane to render to. This isn't normally
a problem, as sensible defaults are set very low in the type path.
However, tracer effects use an appearance override, which was missing
the plane definition.
This adds the plane to the appearance used when apply_vars is called,
by copying it from the holding entity.
bring code up to latest standards, move many procs to named files inside _HELPERS
no idea where to put some of these procs, help is appreciated
made more files to contain some unique code, deleted unsorted.dm, we can rest now
## About The Pull Request
Changes up some layer and plane defines for no particular reason lol
## Why It's Good For The Game
Planes actually override layers, and layers control ordering within planes. A lot of the usage of plane and layer was wholly unnecessary. This refactor helps future maintainability while also being needed staging for _future features._
moves ammo icons, projectile icons and hitscan effect icons to guns folder
renames projectile.dmi to ballistic.dmi so its less confusing
moves rcd ammo from ammo.dmi to tools.dmi with the rcd
Done using this command sed -Ei 's/(\s*\S+)\s*\t+/\1 /g' code/**/*.dm
We have countless examples in the codebase with this style gone wrong, and defines and such being on hideously different levels of indentation. Fixing this to keep the alignment involves tainting the blames of code your PR doesn't need to be touching at all. And ultimately, it's hideous.
There are some files that this sed makes uglier. I can fix these when they are pointed out, but I believe this is ultimately for the greater good of readability. I'm more concerned with if any strings relied on this.

experimental: Hitscanning tracers now have lighting effects
experimental: Projectile pathing has been changed - instead of moving to a turf 32 pixels forward using byond's built in step_towards() proc, it now increments 2 pixel 16 times (subject to change). While this will increase the processing overhead, this will more or less eliminate cases of "projectiles clipping past corners in some angles but not others".
It is my belief that science weaponry should exist but not be "just better energy guns/whatever". Right now, portal guns are actually pretty powerful, as their random teleport can space people (especially if they have bohs), and actually does burn damage, albeit very little. I want to make scilathe weapons into useful utility things that can be weaponized if you use it right and in somewhat niche scenarios.
This PR will make wormhole projectors into more utility than combat.
Moves beam rifle snowflake code up to projectile level for a proper hitscan system.
