LogicType

LogicType is a ushort enum with 350 vanilla values (0-349) that names every logic readable and writable in the game. This page is the enum-value reference: vanilla values, the gas-ratio member catalogue, and the public surface of EnumCollection<TEnum, TInt> (the generic wrapper that backs EnumCollections.LogicTypes and its siblings).

For the runtime registration mechanism (how a mod adds custom values: the five reflection-extension sites, the three name-lookup fallback patches, the module split, and the ScreenDropdownBase Awake-survival behavior), see ../Patterns/LogicTypeRegistration.md. For the canonical SixFive7 value-assignment catalogue and known third-party reservations to avoid, see Patterns/Logic/README.md at the repo root. For the "who registers what" survey of Workshop mods, see ../Patterns/ModLogicTypeRegistration.md.

LogicType enum value inventory (F0040)

LogicType enum (Assets.Scripts.Objects.Motherboards.LogicType): ushort, vanilla values 0-349 with one true gap at 159. Examples: Power = 1, On = 28, Charge = 11, Horizontal = 20, Vertical = 21, PowerPotential = 25, PowerActual = 26, Error = 4, PrefabHash = 84, ReferenceId = 217, PositionX/Y/Z = 76/77/78.

LogicType is [ushort] so values up to 65535 are runtime-legal. The IC10 / MIPS parser resolves name tokens against ProgrammableChip.AllConstants[].Literal via OrdinalIgnoreCase string comparison, so out-of-enum values WORK as long as we register their names in that array.

WirelessPower.CanLogicRead returns true for: Charge, Horizontal, Vertical, PowerPotential, PowerActual, PositionX/Y/Z (plus Device-base ones: Power, On, Error, Mode, RequiredPower, PrefabHash, ReferenceId). PowerTransmitter and PowerReceiver inherit without override.

WirelessPower.GetLogicValue returns: - Horizontal → Horizontal × 360.0 (degrees) - Vertical → Vertical × 180.0 - HorizontalRatio → Horizontal (0..1) - VerticalRatio → Vertical - Charge → AvailablePower = InputNetwork.PotentialLoad - PowerPotential → base.PotentialLoad - PowerActual → base.CurrentLoad = OutputNetwork.CurrentLoad ← delivered watts - PositionX/Y/Z → RayTransform.position

The game stores LogicType identity and metadata across five independent collections that a mod must extend to make a custom value visible end-to-end (Logicable.LogicTypes for NextLogicType cycling, EnumCollections.LogicTypes for the ConfigCartridge UI, ScreenDropdownBase.LogicTypes for motherboard dropdowns, ProgrammableChip.AllConstants for the IC10 compiler, and ProgrammableChip.InternalEnums for screen syntax highlighting). The full extension mechanism, the module split that fires each site at the right time, and the three name-lookup fallback patches live on ../Patterns/LogicTypeRegistration.md.

EnumCollection<T1, T2> lives in Assets.Scripts, NOT Assets.Scripts.Util. ProgrammableChip lives in Assets.Scripts.Objects.Electrical, NOT Motherboards; ProgrammableChip.Constant is a nested public readonly struct.

The MIPS compiler resolves name tokens against ProgrammableChip.AllConstants directly: verified in-game for both l r0 d0 MicrowaveSourceDraw and lbn ... MicrowaveSourceDraw 0. The Hash field on Constant is for the #hash MIPS directive, not pure name lookups.

Atmospheric gas-ratio LogicType members

The bare Ratio = 24 member is the generic ratio readout (used by some non-atmosphere devices for proportional state), unrelated to gas content.

Notably absent: there is no RatioVolatiles member in the current enum. Hydrogen is exposed as RatioHydrogen = 252. Older Stationeers IC10 references that mention RatioVolatiles are from a previous enum revision. Use RatioHydrogen in scripts written against this game version.

For atmosphere-readable devices (those with HasReadableAtmosphere => true, e.g. CombustionDeepMiner), the bare-name members (no Input / Output suffix) read the chamber's internal atmosphere, not any pipe network. The Input / Input2 / Output / Output2 variants read the corresponding pipe networks on devices that expose them.

Gas / fuel relevance for combustion

Cross-reference with Mole.Enthalpy and EnthalpyMultiplier (verbatim tables in ../GameClasses/CombustionDeepMiner.md):

Role Gas Chamber LogicType Enthalpy / Multiplier
Fuel Hydrogen RatioHydrogen 306,000 J/mol
Fuel LiquidHydrogen RatioLiquidHydrogen 306,000 J/mol
Fuel Methane RatioMethane 286,000 J/mol
Fuel LiquidMethane RatioLiquidMethane 286,000 J/mol
Fuel Hydrazine RatioHydrazine 306,000 J/mol
Fuel LiquidHydrazine RatioLiquidHydrazine 306,000 J/mol
Fuel LiquidAlcohol RatioLiquidAlcohol 566,000 J/mol
Oxidiser Oxygen RatioOxygen ×1.0

This is the full set of IC10-readable gases that contribute to Atmosphere.CombustionEnergy accumulation.

Reserved bands

LogicType values are ushort; any 0-65535 value is legal at runtime once injected into EnumCollections.LogicTypes. The full assignment catalogue (SixFive7 mods plus known third-party reservations from a 124-mod Workshop scan: vanilla 0-349, Stationeers Logic Extended 1000-1830, IC10 Inspector/Debugger 500-502 soft, the SixFive7 6571+ allocations) lives in Patterns/Logic/README.md. Cross-check that file before reserving a new band; do not duplicate the table here.

EnumCollection public API

Assets.Scripts.EnumCollection<T1, T2> is the generic wrapper that backs every entry in the static Assets.Scripts.EnumCollections class (LogicTypes, LogicSlotTypes, DeviceModes, etc.). Verbatim public surface from the decompile of Assets.Scripts.EnumCollection2`:

public class EnumCollection<T1, T2> : IEnumCollection
    where T1 : Enum, IConvertible, new()
    where T2 : IConvertible, IEquatable<T2>
{
    public T1[]  Values;
    public T2[]  ValuesAsInts;
    public readonly string[] Names;
    public readonly string[] PaddedNames;
    public readonly string   LongestName;
    public T1 this[int index] => Values[index];
    public int Length { get; }

    public static implicit operator string[](EnumCollection<T1, T2> c);
    public static implicit operator T2[]   (EnumCollection<T1, T2> c);

    public EnumCollection(bool toProper = true);

    public virtual string GetNameFromIndex(int index, bool padded = false);
    public T1[]   GetValues();
    public string GetName(T1 value, bool padded = false);
    public string GetEnumTypeName();
    public string GetNameFromValue(int value, bool padded = false);
    public int    GetIndexFromValue(T1 value);     // throws IndexOutOfRangeException on miss
    public int    GetIntFromIndex(int i);
    public string PrintAll(string begin = "", string end = "");
    public T1     Get(string name);                 // case-insensitive name -> value lookup
}

Lookup directions and miss behavior:

Direction Method Miss behavior
name -> enum Get(string name) Returns default(T1) (NOT exception)
enum -> name GetName(T1 value, bool padded) Returns string.Empty
int -> name GetNameFromValue(int, bool) Returns string.Empty
index -> name GetNameFromIndex(int, bool) Throws (array bounds)
enum -> index GetIndexFromValue(T1) Throws IndexOutOfRangeException
index -> int GetIntFromIndex(int) Throws (array bounds)
index -> enum indexer this[int] Throws (array bounds)

Get(string) body, verbatim:

public T1 Get(string name)
{
    for (int i = 0; i < Length; i++)
    {
        if (Names[i].Equals(name, StringComparison.InvariantCultureIgnoreCase))
        {
            return Values[i];
        }
    }
    return default(T1);
}

Caller pitfall: Get returning default(T1) is indistinguishable from a real hit on whichever enum member maps to the zero value. For unambiguous not-found detection, scan Names directly with Array.FindIndex(coll.Names, n => string.Equals(n, name, StringComparison.InvariantCultureIgnoreCase)) and check for -1, then index coll.Values[i].

The constructor populates Values, ValuesAsInts, Names, and PaddedNames from Enum.GetValues(typeof(T1)) / Enum.GetNames(typeof(T1)) exactly once at static class load, so custom enum values added later by (T1)cast are invisible to Get / GetName / GetNameFromValue until those arrays are resized via reflection. Values and ValuesAsInts are not readonly; Names and PaddedNames are readonly references whose array contents must be replaced via reflection (the valuesField.SetValue(collection, newValues) pattern in LogicableInitializePatch.ExtendEnumCollection).

Why custom LogicTypes don't appear without patches

Early investigation established that vanilla Stationpedia pages for stock devices (like the Microwave Power Transmitter) have a frozen LogicInsert list built once at game startup. Even though Logicable.LogicTypes can be extended at runtime, the page's LogicInsert is populated inside AddLogicTypeInfo which iterates EnumCollections.LogicTypes.Values, a collection constructed from Enum.GetValues(typeof(LogicType)) at EnumCollection<LogicType,ushort> construction time. Our runtime-cast ushort -> LogicType values are NOT in the compiled enum, so Enum.GetValues does not return them. The same construction-time snapshot underlies the other four extension sites; the registration recipe extends all five to make AddLogicTypeInfo naturally discover and emit native rows for custom LogicTypes (this is why the LogicInsert fallback once labelled "Decision 11" is NOT needed under normal operation).

The full enumeration of the five extension sites, the three name-lookup fallback patches, and the module split that ties them together is on ../Patterns/LogicTypeRegistration.md. Per-device CanLogicRead / CanLogicWrite / GetLogicValue / SetLogicValue overrides (which decide whether a particular device responds to the registered LogicType) are an orthogonal concern; see ../Patterns/CustomLogicValueInjection.md.

Verification history

  • 2026-04-20: page created from the Research migration; F0054 is the primary source per MigrationMap §5.1. Additional sources: F0040, F0219a, F0219b, F0244, F0245, F0247 (primary for "why custom LogicTypes don't appear without patches"; F0219v is a duplicate extraction that merges here), F0305, F0316.
  • 2026-04-25: added "Atmospheric gas-ratio LogicType members" section. Verbatim list of all 130+ Ratio* enum members (chamber + per-network variants) decompiled from Assets/Scripts/Objects/Motherboards/LogicType.cs at v0.2.6228.27061. Cross-references combustion-relevant gases against Mole.Enthalpy and EnthalpyMultiplier from ../GameClasses/CombustionDeepMiner.md. Verified via ilspycmd against the local Stationeers install. Confirms RatioMethane, RatioHydrazine, RatioLiquidAlcohol, RatioOzone, RatioLiquidOzone, RatioLiquidHydrazine all exist and are IC10-readable; no RatioVolatiles member in the current enum (Hydrogen exposed as RatioHydrogen = 252).
  • 2026-04-27: added "EnumCollection public API" section. Verbatim public surface (fields, indexer, constructor, all methods) of Assets.Scripts.EnumCollection2decompiled at v0.2.6228.27061 viailspycmdagainst the local Stationeers install. Documents theGet(string name)case-insensitive name-to-value lookup (returnsdefault(T1)on miss, NOT exception), the value-to-nameGetName/GetNameFromValue(returnstring.Emptyon miss), the indexer /GetIndexFromValue/GetIntFromIndex(throw on miss), the implicit operators tostring[]andT2[], and the constructor's one-shotEnum.GetValues/Enum.GetNamessnapshot that explains why custom enum values added via(T1)cast` are invisible until the arrays are resized via reflection. No conflicts with prior page content; section is purely additive.
  • 2026-06-01: split the registration mechanism out of this page into a dedicated ../Patterns/LogicTypeRegistration.md. Removed sections "Four separate LogicType registries", "Three LogicType arrays extension mechanism", "LogicableInitializePatch three-extension-points comment", and "EnumNamePatches class header" (verbatim content preserved on the new page, lossless). Replaced the "Reserved bands" table with a one-line pointer to Patterns/Logic/README.md (the canonical assignment catalogue; the table on this page was stale: it showed 6571-6599 PowerTransmitterPlus instead of the actual 6571-6576 usage and did not list PowerGridPlus's 6577 reservation). Trimmed the in-section "three separate arrays" listing in "LogicType enum value inventory" to a one-paragraph pointer at the new mechanism page. Corrected drift relative to the 2026-05-28 fresh-validator resolution on ./ScreenDropdownBase.md by removing the prior page's references to ScreenDropdownBase as "IC housing on-screen dropdowns" (it actually backs LogicMotherboard condition / action dropdowns on Big Screens, Wall Screens, and Consoles) and the implicit claim that reflection-extension of ScreenDropdownBase.LogicTypes is fragile against Awake (the appended tail survives every Awake). Page now serves only as the enum-value reference. The "five extension sites" framing on the new page consolidates the prior "four registries" vs "three arrays" inconsistency on this page; site 4 (ProgrammableChip.AllConstants) was previously mentioned only in "Why custom LogicTypes don't appear without patches" and not counted in either registry tally. Implementation verified by direct reads of both in-repo registrar mods (Mods/PowerTransmitterPlus/, Mods/PowerGridPlus/).
