Certain things are hard-coded (liquid plasma + light bulb = kaboom), but otherwise most things are simulated. Generally chemicals react with one another to make other chemicals which then do fun things like make explosions.

So how the heck does the liquid simulation work, mechanically? I've seen all sorts of neato crap, like people injecting fuel into a lightbulb and waiting for someone to turn it on and explode. I know a lot of SS13's stuff is harcdoded, did someone just manually script each specific interaction, or does the game somehow do real fluid dynamics? (I assume the former, because holy crap BYOND.)

Alot of object specific things are hardcoded I think. Fluids got added in the last few years so you can make the janitors life even harder

Lots of very specific reactions, but then there's the entire reagents system hanging off to one side where a lot of the EXTREMELY esoteric reactions come from. Reagents traditionally exist in containers and they have a huge byzantine chart of their own reactions from there that they follow. So, like, potassium and water will interact to produce explosions once inside a container. There were/are weird ways of getting reagents into non-container forms like food, smoke, or pills that can assist you in making stranger reactions happen; for a very simple example, if the smoke reaction happens in a container, the smoke produced will contain other reagents from the container. If one of those ingredients is high-fructose corn syrup, any living container that inhales some of the smoke (monkeys or humans) will then process some of that into sugar...which can then interact with other reagents carried in the smoke to make more smoke. This is the basis of many hellsmokes and hellfoams, and much consternation and amusement among the playerbase and administration alike.

I've seen many, many strange chemical reactions, but I've never been enough of a chemistry whiz to sit down and engineer any bullshit. It's funny enough dosing cigarettes with explosive liquids, or w/e.

Fun fact: liquid plasma and lightbulbs is so ancient, it wasnt even in the combat log since every admin for a long time knew how to do it and used it for mischief at some point and could spot others doing it.

I spent a good chunk of a round on Outpost Zeta once in the dark, subverting all the light bulbs and waited for a good moment to flip the outpost's power grid back on. Sounded like an artillery barrage, lot's of "WHAT THE gently caress WAS THAT" over the radio.

I don't remember giving Grump any negative-value behaviors, but hey, good idea.
Grump escalates the harder you push the engine and it's Grump that increases the risks of angry grinding noises, shockwave, zaps, fireflash and such from the generator itself - the immediate hazards to the operator. Feeding weed into the furnaces will decrease Grump. Feeding corpses into the engine will decrease grump AND increase the engine efficiency multiplier, leading to even higher power levels.

Can it be monkey corpses? Would give engineering a reason to order monkeys. Need more legit reasons for people to order crates of monkeys.

Is there any difference in efficiency/grump value between dead humans and alive ones? :v:

I have no idea how that would even be tracked to begin with, but the person setting up the engine and hellburn specifically should give a big efficency bonus. Gotta be willing to sacrifice yourself in order to get that number up higher

Counter: Putting the person who set up the engine into it maximizes Grump. The engine recognizes its parent and will avenge them if they are burned in its flames. Plus it gives traitors with "die a glorious death" objectives a new way to off themselves (or engineering nerds) that'll gently caress with the station.

I don't know if it's changed since I last played, but there really needs to be a/all the furnaces in the control room rather than the heart of the engine. Once it starts cooking, it's functionally sealed off with no way to get to them without potentially messing up the hellburn as it gestates.

Just had an annoying engine round where the hot loop inlet pressure went to 0 even though the pipes had 1+e10 pressure. Then in the last moments of the round it fixed itself going straight from 0w to 30Gw.

I put some monkeys in the furnace but could not jot measure their effect

*yep, pandemic. Actually still waiting on COVID test results for myself, got that giant swab up my nose last week and I've been instructed to self-isolate for a couple weeks.
Had several of the symptoms (no fever though) and I'm in like three of the high risk categories.

Hope y'all are hanging in there and I hope space mischief provides some stress relief and company.

Can I suggest making the pipes on the side an add-on for rocket-propulsion/flame-belching via welding some metal pipes on or something? They look like sick afterburners added after the fact rather than part of the "proper" plumbing.

That looks real good either way though :allears:.
