* Nightvision Rework (In the name of color) (#73094) Relies on #72886 for some render relay expansion I use for light_mask stuff. Hello bestie! Night vision pissed me off, so I've come to burn this place to the ground. Two sections to discuss here. First we'll talk about see_in_dark and why I hate it, second we'll discuss the lighting plane and how we brighten it, plus introducing color to the party. https://www.byond.com/docs/ref/#/mob/var/see_in_dark See in dark lets us control how far away from us a turf can be before we hide it/its contents if it's dark (not got luminosity set) We currently set it semi inconsistently to provide nightvision to mobs. The trouble is stuff that produces light != stuff that sets luminosity. The worst case of this can be seen by walking out of escape on icebox, where you'll see this  Snow draws above the lighting plane, so the snow will intermittently draw, depending on see_in_dark and the luminosity from tracking lights. This would in theory be solvable by modifying the area, but the same problem applies across many things in the codebase. As things currently stand, to be emissive you NEED to have a light on your tile. People are bad at this, and honestly it's a bit much to expect of them. An emissive overlay on a canister shouldn't need an element or something and a list on turfs to manage it. This gets worse when you factor in the patterns I'm using to avoid drawing lights above nothing, which leads to lights that should show, but are misoffset because their parent pixel offsets. It's silly. We do it so we can have things like mesons without just handing out night vision, but even there the effect of just hiding objects and mobs looks baddddddd when moving. It's always bothered me. I'll complain about mesons more later, but really just like, they're too bright as it is. I'm proposing here that rather then manually hiding stuff based off distance from the player, we can instead show/hide using just the lighting plane. This means things like mesons are gonna get dimmer, but that's fine because they suck. It does have some side effects, things like view() on mobs won't hide stuff in darkness, but that's fine because none actually thinks about view like that, I think. Oh and I added a case to prevent examining stuff that's in darkness, and not right next to you when you don't have enough nightvision, to match the old behavior `see_in_dark` gave us. Now I'd like to go on a mild tangent about color, please bare with me You ever walk around with mesons on when there's a fire going, or an ethereal or firelocks down. You notice how there isn't really much color to our lights? Doesn't that suck? It's because the way we go about brighting lighting is by making everything on the lighting plane transparent. This is fine for brightening things, but it ends up looking kinda crummy in the end and leads to really washed out colors that should be bright. Playing engineer or miner gets fucking depressing. The central idea of this pr, that everything else falls out of, is instead of making the plane more transparent, we can use color matrixes to make things AT LEAST x bright. https://www.byond.com/docs/ref/#/{notes}/color-matrix Brief recap for color matrixes, fully expanded they're a set of 20 different values in a list Units generally scale 0-1 as multipliers, though since it's multiplication in order to make an rgb(1,1,1) pixel fullbright you would need to use 255s. A "unit matrix" for color looks like this: ``` list(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0 ) ``` The first four rows are how much each r, g, b and a impact r, g, b and well a. So a first row of `(1, 0, 0, 0)` means 1 unit of r results in 1 unit of r. and 0 units of green, blue and alpha, and so on. A first row of `(0, 1, 0, 0)` would make 1 red component into 1 green component, and leave red, blue and alpha alone, shifting any red of whatever it's applied to a green. Using these we can essentially color transform our world. It's a fun tool. But there's more. That last row there doesn't take a variable input like the others. Instead, it ADDS some fraction of 255 to red, green, blue and alpha. So a fifth row of `(1, 0, 0, 0)` would make every pixel as red as it could possibly be. This is what we're going to exploit here. You see all these values accept negative multipliers, so we can lower colors down instead of raising them up! The key idea is using color matrix filters https://www.byond.com/docs/ref/#/{notes}/filters/color to chain these operations together. Pulling alllll the way back, we want to brighten darkness without affecting brighter colors. Lower rgb values are darker, higher ones are brighter. This relationship isn't really linear because of suffering reasons, but it's good enough for this. Let's try chaining some matrixes on the lighting plane, which is bright where fullbright, and dark where dark. Take a list like this ``` list(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, -0.2, -0.2, -0.2, 0 ) ``` That would darken the lighting a bit, but negative values will get rounded to 0 A subsequent raising by the same amount ``` list(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0.2, 0.2, 0.2, 0 ) ``` Will essentially threshold our brightness at that value. This ensures we aren't washing out colors when we make things brighter, while leaving higher values unaffected since they basically just had a constant subtracted and then readded. You may have noticed, we gain access to individual color components here. This means not only can we darken and lighten by thresholds, we can COLOR those thresholds. ``` list(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0.1, 0.2, 0.1, 0 ) ``` Something like the above, if applied with its inverse, would tint the darkness green. The delta between the different scalars will determine how vivid the color is, and the actual value will impact the brightness. Something that's always bothered me about nightvision is it's just greyscale for the most part, there isn't any color to it. There was an old idea of coloring the game plane to match their lenses, but if you've ever played with the colorblind quirk you know that gets headachey really fast. So instead of that, lets color just the darkness that these glasses produce. It provides some reminder that you're wearing them, instead of just being something you forget about while playing, and provides a reason to use flashlights and such since they can give you a clearer, less tinted view of things while retaining the ability to look around things. I've so far applied this pattern to JUST headwear for humans (also those mining wisps) I'm planning on furthering it to mobs that use nightvision, but I wanted to get this up cause I don't wanna pr it the day before the freeze. Mesons are green, sec night vision is red, thermals orange, etc. I think the effect this gives is really really nice. I've tuned most things to work for the station, though mesons works for lavaland for obvious reasons. I've tuned things significantly darker then we have them set currently, since I really hate flat lighting and this system suffers when interacting with it. My goal with these is to give you a rough idea of what's around you, without a good eye for detail. That's the difference between say, mesons, and night vision. One helps you see outlines, the other gives you detail and prevents missing someone in the darkness. It's hard to balance this precisely because of different colored backgrounds (looking at you icebox) More can be done on this front in future but I'm quite happy with things as of now I have since expanded to all uses of nightvision, coloring most all of them. Along the way I turned some toggleable nightvision into just one level. Fullbright sucks, and I'd rather just have one "good" value. I've kept it for a few cases, mostly eyes you rip out of mobs. Impacted mobs are nightmares, aliens, zombies, revenants, states and sort of stands. I've done a pass on all mobs and items that impact nightvision and added what I thought was the right level of color to them. This includes stuff like blobs and shuttle control consoles As with glasses much of this was around reducing vision, though I kept it stronger here, since many of these mobs rely on it for engaging with the game <details> <summary> Technical Changes </summary> filter transitions. Found this when testing this pr, seemed silly. This avoids dumbass overlay lighting lighting up wallmounts. We switch modes if some turfflags are set, to accomplish the same thing with more overhead, and support showing things through the darkness. Also fixes a bug where you'd only get one fullscreen object per mob, so opening and closing a submap would take it away Also also fixes the lighting backdrop not actually spanning the screen. It doesn't actually do anything anymore because of the fullscreen light we have, but just in case that's unsued. Needs cleanup in future. color with a sprite This is to support the above We relay this plane to lighting mask so openspace can like, have lighting vision goggles and such Side affect of removing see_in_dark. This logic is a bit weak atm, needs some work. It's a dupe of the nightvision action button, and newly redundant since I've removed all uses of it trasnparent won't render These sucked Also transparent stuff should never render, if it does you'll get white blobs which suck </details> Videos!

S pretty IMO, and hopefully it helps with forgetting you're wearing X. balance: Nightvision is darker. I think bright looks bad, and things like mesons do way too much balance: Mesons (and mobs in general) no longer have a static distance you can see stuff in the dark. If a tile is lit, you can now see it. fix: Nightvision no longer dims colored lights, instead simply thresholding off bits of darkness that are dimmer then some level. /🆑 * modular edits * see_in_dark * [MIRROR] Adds a unit test to detect double stacked lights [MDB IGNORE] (#19564) * Adds a unit test to detect double stacked lights * we really need to get that night vision pr done * lints fixes --------- Co-authored-by: LemonInTheDark <58055496+LemonInTheDark@users.noreply.github.com> Co-authored-by: Paxilmaniac <paxilmaniac@gmail.com> * Update augments_eyes.dm * Update augments_eyes.dm * eeee --------- Co-authored-by: LemonInTheDark <58055496+LemonInTheDark@users.noreply.github.com> Co-authored-by: SkyratBot <59378654+SkyratBot@users.noreply.github.com> Co-authored-by: Paxilmaniac <paxilmaniac@gmail.com> Co-authored-by: Gandalf <9026500+Gandalf2k15@users.noreply.github.com>
