simple dungeon-weather/fog/dust effects system

[Mooses2k]

START WITH

• Foggy rooms (FogVolumes) - knee-level version and full height version (Volumetric fog (wait for Godot 4 or https://github.com/SIsilicon/Godot-Volumetrics-Plugin (super laggy) or https://www.youtube.com/watch?v=VzLoEfTDM2c in 1.5x1.5x0.5m tiles or based on room rect, filling random rooms) - can be close to ground or total for different looks; heavy fog leads to light-sources lasting half the time?)
• dust floating in air like Maid of Sker that can make you cough and also Black flecks in the darkness simulating sickness like Pathologic https://www.youtube.com/watch?v=yxfd7fDKUMM

OTHER IDEAS

Maybe based on how much the room is used. Prefer cobwebs in unlit rooms and unused rooms, for instance.

• random winds should blow candles periodically, sometimes with enough force to blow candle out
• Very hot, charred, smell of sulfur - light-sources last twice as long, metal armor hinders
• "Rusty, eroded stone, verdigris, dust. Things seem older. A melancholic miasma permeates the corridors which seem to stretch longer. How long have you been here? Exploration Turns occasionally skip forward in time." (some ideas from https://undergroundadv.blogspot.com/2022/05/return-to-castle-redvald-level-1-map.html )

• 322 ala VotE

• frosty breath when cold

and if you make the bounding box for each big enough, like 3x3 tiles, they can move around a bit before getting culled To not go through walls: That depends on the process material we can do stuff with movement and theoretically, we can bounce them, or respawn them, if they go out of bounds the bounding box is used only for actual culling, like frustum culling so if the bounding box isn't on screen, the particles aren't drawn, even if they would be visible

We're going to generate the Area procedurally. Also will use it for #179

Maybe have them attached to origin of floor tiles? in suitable rooms? Might be easiest

basic floor fog to start with

[Mooses2k]

floor fog probably needs fog2.tscn applied per tile in maybe 25% of rooms that don't have candelabras.
