Configuration

Configuration

NeroPower's settings live in config/neropower.properties, managed by Neroland Core's shared config system: the file is created with defaults and comments on first run, every value is range checked, and /neroland config reload applies changes without a restart. Every key below is server-authoritative — on a multiplayer server the server's values win and are synced to clients. NeroPower never reads nerotech.properties; NeroTech's thermal balance stays NeroTech's. The one exception is telemetryEnabled (see Privacy), which is client-local: each player and server decides for themselves.

Permille values are thousandths: 600 = 60 %.

Master toggles

Key	Default	Range	What it does
overloadEnabled	true	—	true: an unmanaged reactor walks the full failure ladder and destroys itself at the top. false (survival-friendly): the ladder is pinned at Unstable — throttled output and alarms, never a failure action.
terrainDamageMode	auto	on / off / auto	Whether a reactor failure breaks blocks. auto = off on a dedicated server, on in singleplayer and LAN. off keeps the blast's damage and knockback (and the machine is still lost) but breaks nothing.
failureRadiusCap	8	1–16	Hard cap on any failure blast radius, whatever the machine asks for.
transmissionEnabled	true	—	true: beamed power links and transfers. false: the blocks place but every beam stays dark.
planetEfficiencyEnabled	true	—	true: the Stirling Generator's cold-face bonus scales with how cold the local ambient is (NeroTech's planet ambient): bonus × (1000 + clamp(−ambient × 5, 0, 1000)) ⁄ 1000 — ambient −80 on a cold planet gives +40 % on top of the bonus, ambient 0 or warmer none. false: the flat bonus everywhere. The RTG ignores it (decay is the same on every world).

Failure ladder

See Failure Stages.

Key	Default	Range	What it does
failureWarningPermille	600	1–1000	Heat (permille of heat capacity) at which a reactor enters Warning (alarm state, full output).
failureUnstablePermille	800	1–1000	Heat at which a reactor enters Unstable (output scaled by unstablePenaltyPermille, warning alert to the owner). Must exceed failureWarningPermille.
failureFailurePermille	1000	1–1000	Heat at which a reactor fails (its failure action runs). Must exceed failureUnstablePermille; ignored when overloadEnabled is false.
failureHysteresisPermille	50	0–1000	A stage is only left downwards once heat drops this far below the threshold that entered it.
failureMinDwellTicks	100	0–72000	Minimum ticks a reactor stays in each stage before it may climb to the next (100 = 5 s).
unstablePenaltyPermille	600	0–1000	Output multiplier while Unstable (600 = 60 %). Failure always yields 0.

Fission reactor

See Fission Reactor.

Key	Default	Range	What it does
fissionNePerRod	120	1–100000	Nominal NE/tick one fresh Fuel Rod contributes at 100 % of the burn-up curve; the core sums every loaded rod, then scales by control rods, preset, upgrades and the failure ladder.
fissionHeatPerRodPerTick	6	0–10000	Heat one rod adds per tick at 100 % of its heat factor (heat factor = output factor + 200 permille). Control rods reduce it in step with output.
fissionBurnupPerTick	8	1–1000000	Burn-up a loaded rod gains per tick, in permille ×1000 (8 = a rod lasts about 125,000 ticks, ~104 minutes, at Balanced).
fissionBurnupCurve	0=1200,200=1000,600=800,1000=300	text	Output factor (permille of nominal) by rod burn-up (permille), as burnup=factor knots interpolated linearly. Fewer than two valid knots falls back to the default.
fissionControlRodPermille	150	0–1000	Output and heat reduction per Control Rod Assembly inside the shell; the factor never drops below 15 %.
fissionPoisonPerTick	2	0–1000	Neutron poison gained per tick while the core runs hot: full output, every usable slot loaded, and the effective control-rod factor above fissionPoisonRodThresholdPermille (0 disables poisoning).
fissionPoisonRodThresholdPermille	900	0–1000	Poison only builds while the effective control-rod factor (permille; 1000 = no assemblies) is strictly above this line. With the defaults one Control Rod Assembly (850) or a SCRAM (150) keeps the core steady and poison decays.
fissionPoisonDecayPerTick	3	0–1000	Poison shed per tick whenever the core is not accumulating it.
fissionPoisonStallPermille	900	1–1000	Poison level at which the core stalls (the xenon pit) until it has decayed 300 below this line.
fissionScorchEnabled	false	—	true: a fission failure also leaves a scorch zone that hurts living creatures for fissionScorchDays real days.
fissionScorchDays	3	1–365	Real (calendar, UTC) days a scorch zone persists.
fissionScorchRadius	6	1–32	Half-edge (blocks) of the cubic scorch zone centred on the failed reactor.

Battery banks

See Battery Banks.

Key	Default	Range	What it does
batteryCellCapacityBasic	500000	1000–100000000	Basic Battery Cell capacity (NE).
batteryCellCapacityAdvanced	2000000	1000–100000000	Advanced Battery Cell capacity (NE).
batteryCellCapacityElite	8000000	1000–100000000	Elite Battery Cell capacity (NE).
batteryCellIoBasic	1000	1–1000000	Basic Battery Cell maximum insert / extract per tick (NE/t).
batteryCellIoAdvanced	4000	1–1000000	Advanced Battery Cell maximum insert / extract per tick (NE/t).
batteryCellIoElite	16000	1–1000000	Elite Battery Cell maximum insert / extract per tick (NE/t).
bankScanRadius	2	1–4	How far (blocks, each axis) a Battery Bank Controller looks for connected cells: 1 = 3×3×3, 2 = 5×5×5, … 4 = 9×9×9.
bankMaxIoCap	64000	1–10000000	Hard cap on a bank's pooled insert / extract per tick; otherwise min(member cell I/O) × member count.
bankPriorityThresholdPermille	300	0–1000	Priority Source mode: a bank only pushes into a neighbour whose own buffer is below this fill. Buffer mode ignores it.
bankCapacityMilestone	32000000	1000–1000000000000	Pooled capacity (NE) at which a bank opens its owner's neropower:bank_capacity milestone record — the Power Bank quest signal. It gates nothing.

Beamed power

See Beamed Power.

Key	Default	Range	What it does
beamRange	128	8–512	Maximum straight-line distance (blocks) a transmitter or relay may beam to its target.
beamLossPermillePerBlock	3	0–100	Loss per block of distance (permille): delivered = sent × (1 − loss/1000)^distance. 3 = about 68 % delivered at 128 blocks; 0 = lossless.
beamTransferPerPass	2000	1–1000000	NE a transmitter or relay sends per pass, before loss.
beamCheckIntervalTicks	5	1–40	Ticks between passes; each pass re-checks line of sight, moves energy and damages anything in the beam.
beamDamage	0.5	0.0–10.0	Damage (half-hearts) dealt every pass to living creatures standing in an active beam; 0 disables the hazard.
beamMaxHops	8	1–32	Longest relay chain a single pass follows before it stops (loop guard).
beamCrossDimension	false	—	true: a transmitter may target an Orbital Receiver in a space dimension from another dimension, paying beamOrbitalHopLossPermille instead of distance loss.
beamOrbitalHopLossPermille	300	0–1000	Fixed loss of a cross-dimension orbital hop (300 = 70 % delivered).

RTG and Stirling

See RTG and Stirling.

Key	Default	Range	What it does
rtgNePerTick	30	1–10000	NE per tick a Radioisotope Generator produces from a fresh Isotope Pellet; halves every rtgHalfLifeDays.
rtgHalfLifeDays	20	1–365	Half-life of a pellet in in-game days (1 day = 24,000 ticks).
rtgCutoffPermille	50	1–999	A pellet is spent once its output falls below this permille of rtgNePerTick (50 = 5 %, about 4.3 half-lives).
rtgSpentPelletPollution	200	0–100000	Pollution burst (NeroTech's regional pollution, never attributed to a player) recorded per Spent Isotope Pellet destroyed as a dropped item — fire, lava, cactus, explosion. 0 disables it.
stirlingNePerHeatUnit	15	1–1000	NE a Stirling Generator produces per unit of heat it draws.
stirlingMaxDrawPerOp	8	1–1000	Hard cap on the heat drawn from a neighbour in one tick.
stirlingDrawPermille	100	1–1000	Share (permille) of the hot neighbour's gradient above ambient drawn per tick.
stirlingColdFaceBonusPermille	500	0–1000	Output bonus while touching a cold sink (water, ice, snow or a NeroTech Radiator); without one the usable gradient is halved. Scaled by the local ambient when planetEfficiencyEnabled is on.

Privacy

Key	Default	Range	What it does
telemetryEnabled	true	—	Anonymous crash reports for errors in NeroPower code (Sentry, EU servers; no names, UUIDs, IPs or world data). On by default; set false to opt out (takes effect on restart). Client-local, never synced. See Privacy.
