## About The Pull Request
FOV as it is currently implemented is incompatible* with wallening.
I'm doin wallening, so we gotta redo things here.
The issue is the masking of mobs. Wallening relies on sidemap (layering
based off physical position), which only works on things on the same
plane (because planes are basically sheets we render down onto)
So rather then masking mobs, let's reuse the masking idea from old fov,
and use it to cut out a bit of the game render plane, and
blur/over-saturate the bit that's masked out.
My hope is this makes things visible in light, but not as much in
darkness, alongside making more vivid shit more easily seen (just like
real life)
Here's some videos, what follows after is the commits I care about
(since I had to rip a bunch of planes to nothing, so the files changed
tab might be a bit of a mess)
Oh also I had to remove the darkness pref since the darkness is doing a
lot of the heavy lifting now. I'm sorry.
Edit:
NEW FOV SPRITES! Thanks dongle your aviator glasses will guide us to a
better future.

## Commits I Care About
[Implements something like fov, but without the planes as layers
hell](a604c7b1c8)
Rather then masking out mobs standing behind us, we use a combo color
matrix and blur filter to make the stuff covered by fov harder to see.
We achive this by splitting the game plane into two, masking both by fov
(one normally and one inversely), and then applying effects to one of
the two.
I want to make the fov fullscreens more gradient, but as an effect this
is a good start
[Removes WALL_PLANE_UPPER by adding a WALL_PLANE overlay to material
walls (init cost comes
here)](2548933739)
@Mothblocks see this. comment in commit explains further but uh, we need
to draw material walls to the light mask plane so things actually can be
seen on them, but we can't do that and also have them be big, so they
get an overlay. Sorry, slight init time bump, about 0.5 seconds. I can
kill it with wallening.
[Moves SEETHROUGH_PLANE above
ABOVE_GAME_PLANE](beec4c00e0)
I don't think it actually wants to draw here
@Time-Green I think this was you so pinging for opinion

## About The Pull Request
It's kinda hacky, but it is nearly the same as just rendering one z
layer.
We allow people to ENTIRELY REMOVE most plane masters from their screen.
This has the side effect of disabling most visual effects (AO is a big
one) which saves a LOT of gpu.
We rely on planes being essentially layers to ensure things render in
the proper order. (outside of some hackyness required to make parallax
work)
I've kept parallax and lighting enabled, so visuals will still look
better then multiz pre plane cube.
It does also mean that things like FOV don't work, but honestly they
didn't work PRE plane cube, and FOV's implementation makes me mad so I
have a hard time caring.
Reduces gpu usage on my machine on tram from 47% to 32%, just above the
27% I get on meta.
I'm happy with this.
Oh also turns out the parallaxing had almost no cost. Need to remove it
as a side effect of what I'm doing but if I could keep it I would.
There's still room for in between performance options, like disabling
things like AO on lower z layers, but I didn't expect it to make a huge
impact, so I left things as is
Also fixes a bug with paper bins not respecting z layer. It came up in
testing and annoyed me
## Why It's Good For The Game
Ensures we can make multiz maps without running into client performance
issues, allows users to customize performance and visual quality.

now limit the rendering intensity of multiz levels. This will make
things look a bit worse, but run a LOT better. Try it out if your
machine chokes on icebox or somethin.

Makes the code compatible with 515.1594+
Few simple changes and one very painful one.
Let's start with the easy:
* puts call behind `LIBCALL` define, so call_ext is properly used in 515
* Adds `NAMEOF_STATIC(_,X)` macro for nameof in static definitions since
src is now invalid there.
* Fixes tgui and devserver. From 515 onward the tmp3333{procid} cache
directory is not appened to base path in browser controls so we don't
check for it in base js and put the dev server dummy window file in
actual directory not the byond root.
* Renames the few things that had /final/ in typepath to ultimate since
final is a new keyword
And the very painful change:
`.proc/whatever` format is no longer valid, so we're replacing it with
new nameof() function. All this wrapped in three new macros.
`PROC_REF(X)`,`TYPE_PROC_REF(TYPE,X)`,`GLOBAL_PROC_REF(X)`. Global is
not actually necessary but if we get nameof that does not allow globals
it would be nice validation.
This is pretty unwieldy but there's no real alternative.
If you notice anything weird in the commits let me know because majority
was done with regex replace.
@tgstation/commit-access Since the .proc/stuff is pretty big change.

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.
image
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.

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
Why It's Good For The Game
Oranges approves so it's good.
