Design stage. This page describes planned mechanics from the design document. Not implemented yet — see Roadmap (milestone M2 for the handbook and first advancements; M13 for world structures, the full advancement set and decor).
The other design sections describe how the industrial complex works. This page covers what you see and do around the physics: how you find out what to build next, how progress is marked, where you can practice before a mistake becomes an accident, what you find in the world, what instruments are made of, and how you decorate your station. The fuel cycle alone takes 60–100 hours and dozens of machines, and the industry ladder doubles that — without this layer a newcomer would give up on the first evening.
| # | Principle | Consequence |
|---|---|---|
| C1 | The handbook explains, instruments show | The handbook never shows live plant values. It teaches you to read instruments, it does not replace them. |
| C2 | Progress is unlocked by materials, not quests | Advancements and handbook chapters mark progress but block nothing. There is no "turn in a quest, get a recipe". |
| C3 | In-game presentation | The handbook is an "Engineer's Handbook", an operating procedure is a document issued with the controller, an operator licence is an ID card. No "tip of the day" windows. |
| C4 | Mistakes belong in the simulator | Every accident can be lived through on the training simulator with no consequences in the world. |
| C5 | The world tells stories | Structures give information (maps, cores, logs, handbook pages) and a few early parts, never finished machines. |
| C6 | One source of truth | Lua help, register tables and tag captions are generated from DeviceDescriptor, not written by hand. |
The goal: in half an hour you understand that (1) this mod is about a whole plant, not one reactor; (2) the first step is coal and steam; (3) where to look for answers.
| Minute | What happens | Mechanic |
|---|---|---|
| 0 | On first join you receive the engineering_handbook (once per player, content.give_handbook_on_join) |
opens on "How the complex works" |
| 0–5 | One picture of the industry ladder; "you are here" — I0 | clickable illustration, each era leads to its chapter |
| 5–15 | Find coal, build a coal boiler and a steam engine on a Create shaft | advancement "First Steam"; chapter "Boiler: water, fuel, pressure" opens |
| 15–25 | The boiler boils dry or overpressures — the relief valve lifts | the first "accident" with no losses: valve whistle, steam cloud; the handbook points to the pressure gauge |
| 25–30 | Place a pressure gauge (instrument_pressure, level A0) |
chapter "Reading instruments": scale, normal, warning, alarm (ISA-101) |
On TRAINING difficulty the first boiler has a larger pressure margin and every chapter ends with "What to do next" hints. On HARDCORE there are no hints. See Multiplayer for difficulty modes.
engineering_handbook is the mod's own book (not Patchouli, so no hard dependency). Content is a datapack that servers can override or extend:

Operating procedures. Building the controller of a major unit (reactor_controller, refinery column, blast furnace, coke battery, generator) gives you an operating_procedure item with a procedure_ref. Put it on a document_lectern next to the panel and anyone nearby can read that unit's procedure — just as real procedures sit at operator workstations.
Lua help in CC: Tweaked. Pages go under data/computercraft/lua/rom/help/ (pc_reactor.txt, pc_plc.txt, pcui.txt, pc_tags.txt …), generated by the Gradle task generateCcHelp from device descriptors. Two pages are hand-written: pcui and pc_start (first program in 10 lines). On a computer, help pc_pump shows the same content as the handbook, sized for a 51×19 screen.
These continue the Create integration scenes (1–25). Each is ≤ 60 s and uses the same formulas as the simulation.

The handbook has a Route tab: a graph of tasks across eras I0–I4 and automation levels A0–A5, inspired by the GregTech: New Horizons questbook — with key differences:
| GT:NH questbook | Prompt Critical Route | |
|---|---|---|
| Blocks progress | no, but recipes follow quest order | no: a task only marks and explains |
| Rewards | loot bags, resources | XP and decor; no resources or machines |
| Completion check | item in inventory | item or plant state: tag value, simulator scenario, run time without a scram |
| Link to text | short description | every task opens a handbook chapter and, where available, a Ponder scene |
| Task type | Condition | Example |
|---|---|---|
obtain |
item in inventory or station container | "Obtain 16 coke" |
build |
multiblock assembled and validated | "Build a blast furnace" |
reach |
plant tag in range for a given time | "Hold boiler drum pressure at 1.2 ± 0.1 MPa for 10 minutes" |
operate |
unit runs without a trip for a given time | "Generator on the grid for 1 game day" |
scenario |
simulator scenario passed | "Pass out_of_phase_sync" |
program |
PLC/Lua program does the job on the digital twin | "Write a PI level controller, error < 5 %" |
discover |
structure or deposit sign found | "Find a bitumen seep" |
choice |
one of several (a fork) | "Choose your path to the atom" |
Target: 30–60 tasks per era and 15–25 per automation level, about 300 at release. The graph lives in data/promptcritical/handbook/route/<era>.json; CI checks that it references only existing items, blocks, tags and scenarios. Hints: full "how" on TRAINING, only "what" on STANDARD, titles of open tasks only on HARDCORE.
Advancements are vanilla (data/promptcritical/advancement/...) so they work in the vanilla screen, chat and third-party trackers. Almost all conditions use one custom trigger, promptcritical:sim_event, with predicates on domain events. With station_member: true an advancement counts for every station member online within 64 m of the controller — a shared shift success. Rewards are XP and the record only. Types: task, goal, challenge; (H) = hidden.

Station record board. station_record_board shows station records from the historian: days without scram, 30-day capacity factor, output, product yield, collective dose. /pc stats compares stations on a server.
Real NPP, refinery and grid operators train for years on full-scope simulators. In the game the simulator lets you survive any accident without consequences, delivers lesson content, and tests programs before they go to real hardware (it is the consumer of the digital twin, see Automation Platform).
| Block | Function |
|---|---|
training_simulator |
compute cabinet; runs an isolated copy of SimulationWorld
|
simulator_console |
simulator panel; normal panel blocks and CC computers attached to it work on the copy |
instructor_station |
start, pause, rewind, fault insertion, scoring |
A copy is made either from your real station (snapshot of the chosen controller and all connected networks: hydraulic, electrical, PLCs, safety systems — the Minecraft world itself is not copied) or from a reference plant in the datapack: I0 boiler, generator unit with grid, T0, T1, PR-300, crude distillation column, compressor station, well with rig.
Scenario format (example):
{
"id": "promptcritical:stuck_porv",
"plant": "promptcritical:pr300",
"initial": { "preset": "full_power_mol" },
"faults": [
{ "t": 30, "type": "VALVE_STUCK_OPEN", "target": "rcs.pzr.porv", "indication": "COMMAND" },
{ "t": 30, "type": "SENSOR_FAIL", "target": "rcs.pzr.porv.position", "mode": "FROZEN" }
],
"success": [ { "within": 900, "all": ["core.cladding.max_temp < 1477", "operator.found:rcs.pzr.porv"] } ],
"failure": [ "core.cladding.max_temp >= 1477" ],
"debrief": "promptcritical:lessons/stuck_porv"
}Fault types: sensor (FROZEN, DRIFT, OPEN_LOOP, NOISY), stuck valves (STUCK_OPEN, STUCK_CLOSED, STUCK_AT), pump or compressor failure, pipe break of a given size, bus power loss, PLC WATCHDOG, wrong indication (COMMAND — lamp shows the command, not the position), safety system failure on demand, fire, gas release. The instructor can insert faults live. After a scenario, a lesson page debriefs what happened, which instruments showed it and when, and where time was lost — from the copy's historian trends.
Lessons are presented as engineering lessons without naming real sites or countries.

operator_license is an ID item with a license_spec: level (TRAINEE, OPERATOR, SHIFT_SUPERVISOR), plant type, date, station signature. It is issued for passing a set of simulator scenarios with a score ≥ content.license_pass_score (0.75). A server may require it (ops.require_license, default false): then control keys and bypass keys turn only for players with a valid licence of the right level, and the station log shows actions by licence number.
Structures are vanilla structure + structure_set in the datapack, tuned by worldgen.structures.*. Loot is information and early parts: cores, geological_map (marks the nearest ore body or trap, like a treasure map), handbook pages, logs, broken instruments to salvage, a little coal, steel and copper wire. No finished machines, fuel assemblies or category 1–2 sources — except where the source itself is the hazard.

Power thyristors from NTD silicon are the real main application of neutron transmutation doping (Isotopes and RTG). They are needed for variable_frequency_drive (soft speed control of pumps and centrifuges, ESP drives) and grid static compensators (backlog). Ordinary ICs do not need NTD silicon; otherwise level A4 would sit behind the reactor.

Czochralski window: pull rate 0.5–2 mm/min and rotation 5–30 rpm. Outside it you get polycrystal and zero yield. The ingot grows visibly out of the crucible.
Clean room. wafer_fab is a multiblock: cleanroom_panel walls, HEPA ventilation (hepa_filter), airlock. Particle concentration inside is C = C_out · L / (L + n·V·η_HEPA) with η_HEPA = 0.9997; leakage L grows with open doors, player passages and unsealed blocks. Chip yield follows the Poisson model Y = e^(−D₀·A) with defect density ∝ C. A dirty room means scrap — ventilation becomes a production problem, not only a radiological one.

Otherwise level A4 would be available in the first minutes and the automation ladder would collapse. Servers that run other CC mods can turn it off.

Asphalt is the first use of bitumen, long before a refinery: bitumen from a pitch_lake + gravel → asphalt in a Create mixer. Walking on asphalt is 15 % faster (content.asphalt_speed_bonus) — a natural reason to pave roads between plant units.
