Brings a heavily improved, rewritten, and optimised fermichem to tg. I saw that tg seemed receptive to it, so I thought I’d do it myself. If you know of fermichem – there’s a lot changed and improved, so looking at other documents regarding it will not be accurate.
Revamps the main chemistry reaction handler to allow for over time reactions instead of instant reactions. This revamp allows for simultaneous reactions, exo/endothermic reactions and pH consuming/producing behaviours. Most of the reactions in game will now inherit an easy one size fits all reaction.
Temperature mechanics
Temperature affects reaction rate
The higher it is, the faster it is, but be careful, as chem reactions will perform special functions when overheated (presently it DOESN’T explode)
Temperature will increase or decrease depending on the exo/endothermic nature of the reaction
pH mechanics
Each reaction requires the pH of a beaker to be within a certain range.
If you are outside of the optimal, you'll incur impurity, which has a negative effect on the resultant chem
pH of a beaker will change during a reaction
Reacting Impure chem effects can vary from chem to chem, but for default will reduce the purity of other reagents in the beaker
Consuming an impure chem will either cause liver or tox damage dependant on how impure it is as well as reducing consumed volume
Purity can (presently) only be seen with a chemical analyser
Impure chems can purposely be made by making the reagent with a low, but not explosive, purity.
A chem made under the PurityMin will convert into the reagent’s failed chem in the beaker.
Optional catalysts
Reactions can use an optional catalyst to influence the reaction - at the more framework exists from tmeprature, reaction rate and pH changes as a result of a catalyst. Catalysts can be set to only work on a specific reagent subtype. It is preferable to those building upon this code that optional catalysts only affect a subsection of reagents.
Presently the only catalyst that uses this is Palladium synthate catalyst - a catalyst that increases the reaction speed of medicines.
Reaction agents
These are reagents that will consume themselves when added to a beaker - even a full one, and apply effects to the total solution. One example being Tempomyocin which will speed up a reaction, or the buffer reagents which change the pH.
Competitive reactions
These reactions will go towards a certain product depending on the conditions of the holder. The example one given is a little tricky and requires a lot of temperature to push it towards one end.
New and charged reactions
(see the wiki for details)
Acidic /basic buffer - These reagents will adjust the pH of a beaker/solution when added to one. If the beaker is empty it will fill it instead.
Tempomyocin - This will instantly speed up any reaction added it is added to, giving it a short burst of speed. Adding this reagent to a reaction will give it a suddent speed boost up to 3x times - with the output purity of the boost modified by the Tempomyocin's purity.5u per 100u will give you 2x, 10 u per 100u will give you 3x. IIt caps at 3x for a single addition, but there is nothing preventing you from adding multiple doses for multiple boosts.
Purit tester - this will fizzle if the solution it is added to has an inverse purity reagent present.
A few other reactions have been tweaked to make sure they work too. An example being meth - see the wikipage linked above.
A note on all reactions
The one size fits all reaction for all chems generally won’t create impure chems – it is very forgiving. The only thing to remember is to avoid heating reactions over 900 or you’ll reduce your yield, and try to keep your pH between 5 -9.
This PR doesn’t have specific example chems included (except for the buffers) – they will be atomised out and they use the mechanics in more depth
A note on plumbing
I reached out to Time Green and we worked together to make sure plumbing was fine. Time Green did some of his own tests too, and surprisingly it doesn't look like much needs to be changed.
