Common fields

Fifteen tables use one shared row schema, called the generic schema here (in the code, GenericRecipe and its codec GenericRecipeCodec; it is the same schema ntm-next uses, so one file works for both ports). The other tables have a record of their own, but they build it from the same pieces: the same ingredient forms, item outputs, fluid stacks and material stacks. This page describes both.

Tables on the generic schema: assembly_machine, precision_assembler, chemical_plant, mixer, blast_furnace, difurnace, purex, exposure_chamber, fluid_breeder, outgasser, fusion, plasma_forge, rock_mill, supercomputer, space_assembler. Three of them add fields of their own (fusion, plasma_forge, outgasser), listed on their pages.

Field	Type	Required	Default	Meaning
name	string	yes		Internal name. Machines save it, the selector shows it. Unique per table (see below).
input_items	list of ingredients	no	none	Item inputs.
input_fluids	list of fluid stacks	no	none	Fluid inputs.
output_items	list of outputs	no	none	Item outputs, or one weighted choice.
output_fluids	list of fluid stacks	no	none	Fluid outputs.
duration	int	no	0	Ticks per operation at normal speed.
power	long	no	0	Energy (HE) drawn per tick while running. Some machines ignore it; their pages say so.
icon	item stack object	no	first output	Icon in the selector and recipe viewers. Must be the object form {"id": ...}.
custom_localization	boolean	no	false	Show the translation of name as the recipe’s title (1.7 setNamed) instead of the icon’s item name.
name_wrapper	string	no	none	A translation key that wraps the title, with the title as its argument (purex.recycle gives “Reprocessing of …”).
blueprint_pools	list of strings	no	none	Blueprint pools the recipe belongs to. A pooled recipe runs only with a blueprint of one of its pools in the machine.
auto_switch_group	string	no	none	Auto-switch group (see below).
order	int	no	after all HBM rows	Position in the table; see order.
input_items_expensive	list of ingredients	no	none	Replaces input_items while expensive mode is on (1.7 inputItemsEx).
input_fluids_expensive	list of fluid stacks	no	none	Replaces input_fluids while expensive mode is on.
blueprint_pools_528	list of strings	no	none	Replaces blueprint_pools while 528 mode is on (1.7 setPools528).
requires	list of strings	no	none	Config conditions the row needs to exist; see requires.

Notes:

• Icon. Without icon, the recipe shows its first item output; with no item output, a fluid droplet of its first output fluid, else of its first input fluid.
• Names. Within one table, two active rows must not share a name. If they do, the row that comes first in order is kept and the other is dropped with a log warning. HBM names its rows <prefix>.<thing> (chem.oxygen, ass.acidizer, precass.atomic_clock); the prefix is only a convention.
• Blueprint pools. A pool is a string such as 528.arty or alt.plates. The blueprint item hbm:blueprints carries one pool in its blueprint_pool item data. A recipe with pools is cleared from a machine whose blueprint slot does not hold a blueprint of one of them. HBM’s pool names start with alt., discover., secret. or 528..
• Auto-switch groups. While a recipe of a group is selected, a machine that finds the first input of another recipe of the same group in its input slots switches to that recipe. The group string is also a translation key, shown in the recipe’s tooltip. HBM uses it, for example, for the cyclotron particles in the assembly machine (autoswitch.cyclotron) and PUREX fuel families (autoswitch.plate, autoswitch.watz).
• Expensive and 528 variants are part of the same row. The row keeps its name; only the inputs or pools in force change with the config.

Item outputs of generic rows

output_items entries take these forms:

"output_items": [
  "hbm:ingot_desh",
  { "id": "hbm:part_copper", "count": 8 },
  { "id": "hbm:circuit_chip", "count": 8, "chance": 0.75 },
  { "id": "hbm:canister_full", "item_data": { "fluid": "hbm:oil", "fluid_amount": 1000 } },
  { "tag": "c:nuggets/naquadria", "count": 12 }
]

Form	Meaning
"id"	One item.
{"id", "count", "chance", "item_data"}	count defaults to 1. chance (0 to 1) rolls once per item of the stack, so count: 4, chance: 0.25 averages one item; leave it out for a guaranteed output. item_data is item data.
{"tag", "count", "chance"}	The first item of an item tag, looked up when the table loads (1.7’s OreDictionary.getOres(name).get(0)). If the tag is empty the output is empty, so such a row should also require the tag. Note the tag is written without # here.

A weighted choice gives exactly one of several items. It must be the only entry of output_items, written as a list inside the list:

data/hbm/recipe/precision_assembler/atomic_clock.json (HBM, shortened)

"output_items": [
  [
    { "data": "hbm:circuit_atomic_clock", "weight": 50 },
    { "data": { "id": "hbm:broken_item", "item_data": { "broken_item": "hbm:circuit_atomic_clock" } }, "weight": 50 }
  ]
]

data is an item stack and weight a number; one entry is picked per operation, by weight.

Requires

requires lists conditions. A row is in its table only while every entry holds. Prefix an entry with ! to negate it. An entry is either a config flag or # plus an item tag:

Entry	Holds when
enable_528	528 / enable528Mode is on.
expensive_mode	01_general / 1.99_enableExpensiveMode is on.
enable_528_pressurized	528 / X528_enable528PressurizedRecipes is on (always off unless 528 mode is on).
lbsm	LESS BULLSHIT MODE / enableLessBullshitMode is on (always off in 528 mode).
lbsm_simple_chemistry	LBSM and LBSM_recipeSimpleChemistry are on.
lbsm_simple_centrifuge	LBSM and LBSM_recipeSimpleCentrifuge are on.
lbsm_simple_crafting	LBSM and LBSM_recipeSimpleCrafting are on.
lbsm_simple_alloy	LBSM and LBSM_recipeSimpleAlloy are on.
lbsm_unlock_anvil	LBSM and LBSM_recipeUnlockAnvil are on.
lbsm_simple_armor	LBSM and LBSM_recipeSimpleArmor are on.
lbsm_simple_tool	LBSM and LBSM_recipeSimpleTool are on.
lbsm_simple_medicine	LBSM and LBSM_recipeSimpleMedicine are on.
#<tag>	The item tag has at least one item, e.g. #c:nuggets/naquadria (1.7’s “only if another mod adds this ore dictionary entry” rows).

The config names are the category and key in config/hbm.cfg. An unknown flag name never holds: the row is left out with a warning in the log.

"requires": ["enable_528", "!expensive_mode"]

Which tables read requires, and when they test it again:

• Generic-schema tables: whenever a flag value changes, at the next use. No reload needed.
• centrifuge, soldering: the same, no reload needed.
• annihilator, anvil_construction: when the table loads (/reload).
• crystallizer has a different requires: one tag id, without #, as a single string. See its page.
• The other tables have no requires.

The same flags (not the #tag form) also work in the golem:requires key, which every recipe file of any type can carry; see removing recipes.

Ingredients

Item inputs of most tables accept one ingredient object. It has several forms, told apart by their keys.

Item or tag

{ "ingredient": "minecraft:clay_ball", "count": 7 }
{ "ingredient": "#c:ingots/steel", "count": 64 }

Field	Type	Required	Default	Meaning
ingredient	item id, or # and an item tag	yes		What matches.
count	int	no	1	How many the recipe takes (some machines ignore it; see their pages).
exact	boolean	no	false	Match only an item with exactly the given data (see below).
item_data	item data	no	none	The data an exact ingredient must have. Implies exact.

A plain item ingredient matches the item with any data: "hbm:canister_full" matches a canister of any fluid. To match one data value, use exact:

{ "ingredient": "hbm:broken_item", "exact": true, "item_data": { "broken_item": "hbm:circuit_atomic_clock" } }

"exact": true without item_data matches only the item with no data, for example an unloaded artillery shell (assembly_machine/shellchlorine.json). A tag cannot be exact.

Autogen material shape

{ "material": "steel", "shape": "weldedplate", "count": 2 }

Field	Type	Required	Default	Meaning
material	material name	yes		An HBM material, by its name (steel, titanium, aluminium, …).
shape	shape name	yes		One of the shapes below.
count	int	no	1

This matches HBM’s generated per-material items that share one item model and differ only in material: wires, dense wires, bolts, cast and welded plates, shells, pipes, gun parts and the like. Shape names: nugget, tiny, fragment, dusttiny, wire, bolt, billet, ingot, gem, crystal, dust, densewire, plate, castplate, weldedplate, shell, pipe, heavy_component, lightbarrel, heavybarrel, lightreceiver, heavyreceiver, mechanism, stock, grip, block, ore. It only matches when HBM generates an item for that material and shape. For ingots, plates, dusts and the like, prefer the c: tag (#c:plates/steel), which also accepts other mods’ items.

Typed ingredients

These carry a type key:

type	Fields	Matches
hbm:fluid_container	fluid (fluid id), amount (int, mB), count (default 1)	Any full fluid container that holds amount mB of fluid (1.7’s fluid dictionary entries).
hbm:fluid_item	item, fluid, count (default 1)	That container item holding fluid, at any fill.
hbm:cold	item, count (default 1)	That item when it is not hot: spent fuel that has cooled in a waste drum.
hbm:any_of	of (list of ingredients), count (default 1)	Any one of the listed ingredients, each matched with its own count.

{ "type": "hbm:fluid_container", "fluid": "hbm:diesel", "amount": 1000 }
{ "type": "hbm:fluid_item", "item": "hbm:canister_full", "fluid": "hbm:gasoline" }
{ "type": "hbm:cold", "item": "hbm:waste_plate_mox" }
{ "type": "hbm:any_of", "of": [{ "ingredient": "#c:ingots/coal" }, { "ingredient": "#c:dusts/coal" }] }

Stirling engine

The anvil_smithing, anvil_construction, press, ammo_press, arc_welder, soldering, combination, particle_accelerator and sawmill tables also accept:

{ "type": "hbm:stirling", "item": "hbm:machine_stirling", "has_cog": false }

It matches a Stirling engine with (true) or without (false) its gear. Both fields are required.

Plain item-or-tag strings

Some keyed tables take a plain string instead of an ingredient object: an item id or # and a tag, no count ("input": "#c:ingots/iron"). These are shredder, liquefaction, material_distribution, lemegeton, magic and the pedestal grid. A few fields take a plain item id only, with no tag: breeder and electrolyser_metal inputs and the cyclotron particle. Each page says which form a field takes.

Item stacks

Where a table outputs a single item stack (most record tables), the form is:

Form	Meaning
"id"	One item.
{"id", "count", "item_data"}	count defaults to 1; item_data is optional item data.

Some record tables take an item output without data: "id" or {"id", "count"} only. Each page says which form a field takes.

Item data

Item data states the few HBM data values a recipe may need, in one form on every Minecraft version (never raw NBT or data components):

Field	Type	Meaning
fluid	fluid id	The fluid of a container, fluid icon or fluid-holding item.
fluid_amount	int	The fill in mB.
fluid_pressure	int	The fluid’s pressure.
broken_item	item id string	What a hbm:broken_item is broken from.
blueprint_pool	string	The pool of a hbm:blueprints item.

{ "id": "hbm:fluid_pack_full", "item_data": { "fluid": "hbm:oxygen", "fluid_amount": 32000 } }
{ "id": "hbm:blueprints", "item_data": { "blueprint_pool": "528.arty" } }

Fluid stacks

{ "type": "hbm:lightoil_crack", "amount": 500, "pressure": 1 }

Field	Type	Required	Default	Meaning
type	fluid id	yes		Any registered fluid: HBM’s (hbm:oxygen), vanilla’s (minecraft:water, minecraft:lava) or another mod’s.
amount	int	yes		mB.
pressure	int	no	0	Pressure level. A machine’s input tank must hold the fluid at exactly this pressure; fluid is pressurised in the compressor.

Fluids are named by their vanilla registry id. HBM’s own fluids are hbm:<name> in lower case.

Material stacks

Molten metal in the crucible, foundry and arc furnace is counted in quanta: 72 to the ingot, 8 to the nugget.

{ "material": "steel", "amount": 72 }

Field	Type	Required	Meaning
material	material name	yes	An HBM material by name.
amount	int, above 0	yes	Quanta.
