Industrial Elixir API

Industrial Elixir exposes a small public API under the com.skniro.industrial_elixir.api package. This page documents the main entry points for addon developers.

Energy Tier

com.skniro.industrial_elixir.api.energytier.EnergyTier

An enum describing the EU-style energy tiers used throughout the mod.

public enum EnergyTier {
    TIER1(32, 32),
    TIER2(128, 128),
    TIER3(512, 512),
    TIER4(2048, 2048),
    TIER5(8192, 8192),
    INFINITE(Integer.MAX_VALUE, Integer.MAX_VALUE);

    public int getMaxInput();
    public int getMaxOutput();
}

Tier	Max Input/Output
TIER1	32 E/t
TIER2	128 E/t
TIER3	512 E/t
TIER4	2048 E/t
TIER5	8192 E/t
INFINITE	Integer.MAX_VALUE

Tiered Energy Item

com.skniro.industrial_elixir.api.item.TieredEnergyItem

An interface for items that store energy and belong to an energy tier. Implementing it lets your item be charged by Charge Pads and recognized by the energy system.

public interface TieredEnergyItem {
    EnergyTier getEnergyTier();
}

Example:

public class MyBatteryItem extends Item implements TieredEnergyItem {
    @Override
    public EnergyTier getEnergyTier() {
        return EnergyTier.TIER2;
    }
}

Replicator Value Map

com.skniro.industrial_elixir.api.item.replicator.ReplicatorValueMap

A registry that maps items to their replication cost (UU-matter mB + energy EU). The Pattern Storage scanner and the Replicator machine query this map.

public static void register(Item item, int uuCost, long energyCost);
public static ReplicatorCost get(Item item);
public static boolean contains(Item item);
public static Map<Item, ReplicatorCost> getAll();

ReplicatorCost is a record:

public record ReplicatorCost(int uuCost, long energyCost) {}

Example — register your item for replication:

ReplicatorValueMap.register(ModItems.MY_INGOT, 25, 0);

Default costs are registered during mod init via registerDefaults() (e.g. Rubber 101 UU, Iridium Shard 13 UU, Iridium Plate 520 UU, Scrap 1 UU).

Fuel Registry

com.skniro.industrial_elixir.api.item.ModFuelRegistry

Register custom fuels for the Coal Generator and Solid Fuel Heater.

public static void registerFuel(Item item, int burnTime);
public static void registerFuel(TagKey<Item> tag, int burnTime);

Burn time is in ticks (like vanilla). The Coal Generator burns fuels at half the vanilla duration; mod fuels registered here are used directly.

Example:

ModFuelRegistry.registerFuel(ModItems.MY_COAL, 1600);
ModFuelRegistry.registerFuel(TagKey.create(Registries.ITEM, ResourceLocation.parse("mymod:my_fuels")), 800);

Machine Provider Interfaces

com.skniro.industrial_elixir.api.block.MachineEnergyProvider

Implemented by machines that want to expose their energy capacity and per-craft cost.

public interface MachineEnergyProvider {
    long getMachineCapacity();
    long getCraftEnergyCost();
}

com.skniro.industrial_elixir.api.block.MachineRecipeProvider

A functional interface that returns the current recipe type of a machine.

@FunctionalInterface
public interface MachineRecipeProvider {
    RecipeType<?> getCurrentRecipeType();
}

Data Generation: Recipe Builders

The mod provides fluent builders for every machine recipe type under com.skniro.industrial_elixir.api.data.recipe. The base class ModRecipeGenerator (extends vanilla RecipeProvider) is the easiest way to use them.

Available builders:

Builder	Recipe type
MaceratorRecipeJsonBuilder	Macerator
CompressorRecipeJsonBuilder	Compressor
ExtractorRecipeJsonBuilder	Extractor
MetalFormerRollingRecipeJsonBuilder	Metal Former — Rolling
MetalFormerCuttingRecipeJsonBuilder	Metal Former — Cutting
MetalFormerExtrudingRecipeJsonBuilder	Metal Former — Extruding
CuttingRecipeJsonBuilder	Cutting Machine
OreWashingRecipeJsonBuilder	Ore Washing
HeatCentrifugeRecipeJsonBuilder	Heat Centrifuge
ModBlastFurnaceRecipeJsonBuilder	Blast Furnace
MolecularTransformerRecipeJsonBuilder	Molecular Transformer
BrewReactorRecipeJsonBuilder	Brew Reactor
CoffeeMachineRecipeJsonBuilder	Coffee Machine
CropFarmRecipeJsonBuilder	Crop Farm

Example — add a Macerator recipe in your own data generator:

public class MyRecipeGenerator extends ModRecipeGenerator {
    // ...
    @Override
    public void buildRecipes() {
        createMacerator(MyItems.MY_DUST, 2)
            .input(MyItems.MY_ORE)
            .save(output);
    }
}

The Metal Former Rolling and Cutting builders automatically generate matching workbench recipes using the Hammer/Cutter items.

Wood Set Helper

ModRecipeGenerator.addWoodSet(...) generates the four Cutting Machine recipes (log → planks, stripped log → planks, wood → planks, stripped wood → planks) for a full wood set.

public void addWoodSet(RecipeOutput exporter,
                       ItemLike log, ItemLike strippedLog,
                       ItemLike wood, ItemLike strippedWood,
                       ItemLike planks, String name);

Energy Tooltip Helper

com.skniro.industrial_elixir.api.item.EnergyTooltipHelper

A helper for drawing the cyan-blue energy tooltip on items that store energy. Use it when rendering tooltips for custom energy items.
