Gasworks

# Gasworks 0.4.2

It covers a lot of ground: two new machines, all recipes moved to datapacks, rebuilt machine screens, and support for JEI and Jade.

## New machines

**Synthesis Reactor.** Until now you could only take gases apart. The reactor puts them
together: two gases in, one out, with an optional catalyst and a heat requirement. Six
recipes ship with it, most lifted from real industrial chemistry — hydrogen and nitrogen
over an iron catalyst make ammonia, methane and steam reform into hydrogen, methane cracks
into acetylene over soot.

Heat is a resource, and not all heat is equal: a magma block under the reactor gives one
level, fire two, lava three. Catalysts sit in their own slot and are consumed roughly once
every eight operations, so iron ingots, graphite and soot finally have a sink.

**Hyperbaric Press.** Every other machine treats pressure as a limit to respect. This one
treats it as the resource you have to push, and it is the first machine that can genuinely
take your base with it. Feed it a gas and an item and it winds itself up bar by bar toward
the pressure the recipe demands. The safe ceiling is 60 bar; every bar above that adds a
per-tick chance of catastrophic failure — the press is destroyed, its charge is dumped into
the room as gas, and it explodes with a force that scales with how far you pushed it.

A second tank takes any cryogenic gas and divides that risk by twenty while it lasts.
Running at 100 bar without coolant is a decision, not an accident.

Coal blocks compress into compressed carbon at 50 bar, and compressed carbon becomes a
**diamond** at 100. A helium crystal under cryomist yields a **pressure crystal** at 80,
and at 150 bar a fusmog ingot becomes **voidsteel** — the most dangerous thing you can make.

## Recipes are datapack recipes

Every machine recipe now lives in `data/gasworks/recipe/` under its own type: `separating`,
`solidifying`, `synthesising` and `pressing`. A modpack can add, change or remove any of
them with a datapack, without touching the mod. Energy cost comes from the recipe itself,
so different recipes can cost different amounts.

## Machine screens, rebuilt

All twelve machines used to share one generic panel: three anonymous tank bars and no way
to tell which was which. Each machine now has its own layout. The Hyperbaric Press shows a
*Process gas* tank and a *Coolant* tank; the reactor shows *Input A*, *Input B* and
*Output* plus its heat level against what the recipe needs; the generator shows *Fuel* and
*Exhaust*. Every empty slot names what belongs in it.

A status line says why a machine is stopped — "Not enough heat", "Pressure too low",
"Building pressure" — instead of leaving you to guess.

**Fixed:** the energy bar was reading truncated values for any machine above 32767 FE,
which is all of them. It has been wrong since the first machine shipped.

## Mod compatibility

**JEI.** Four categories — Gas Separation, Gas Solidification, Gas Synthesis and Hyperbaric
Pressing — each showing the gases and amounts involved, energy cost, and the heat or
pressure required. Registered against the machine that runs them, so clicking a Gas
Separator lists everything it can separate.

**Jade.** Point at a machine and the tooltip gives its status, charge and every tank named
the way the screen names it. Pipes show what is in them, cables their buffer. Gas clouds
show density and warn when the gas is harmful to breathe or flammable.

Both are optional — the mod runs exactly as before without either.

## Also

- Redrawn machine textures: each block now carries its own emblem instead of a coloured
  stripe on an identical grey plate.
- `/gasworks recipes` reports how many recipes of each type actually loaded.
