Diffuser Fuel & Liquid Colors

Three more NeoForge data maps on the item registry control the garlic and fog diffusers and the colour of items in the alchemical cauldron. They use the same file wrapper as Blood Values (replace, values, remove, neoforge:conditions) and are all synced to the client. There are no JSON schemas for them.

Data map	File	Value
`vampirism:garlic_diffuser_fuel`	`data/vampirism/data_maps/item/garlic_diffuser_fuel.json`	`{ "burn_duration": int }`
`vampirism:fog_diffuser_fuel`	`data/vampirism/data_maps/item/fog_diffuser_fuel.json`	`{ "burn_duration": int }`
`vampirism:liquid_color`	`data/vampirism/data_maps/item/liquid_color.json`	int (RGB colour)

File location

A data map file lives in the namespace of the data map itself, so these always go to data/vampirism/data_maps/item/<name>.json (like item_blood.json). Any data pack can ship such a file to add entries (merged) or replace / remove them. The generated defaults are in projects/vampirism/src/generated/resources/data/vampirism/data_maps/item/.

Garlic and fog diffuser fuel

Items listed in garlic_diffuser_fuel can be put into the fuel slot of the garlic diffuser (hunter block), items in fog_diffuser_fuel into the fog diffuser (vampire block). When the diffuser is not burning and has an item with a burn duration above 0 in its fuel slot, it consumes one item and stays active for burn_duration ticks. Items without an entry have a burn duration of 0 and are not used as fuel.

Field	Type	Description
`burn_duration`	int	How long one item keeps the diffuser burning, in ticks (20 ticks = 1 second).

data/vampirism/data_maps/item/garlic_diffuser_fuel.json (generated default)
{
  "values": {
    "vampirism:purified_garlic": { "burn_duration": 108000 }
  }
}

data/vampirism/data_maps/item/fog_diffuser_fuel.json (generated default)
{
  "values": {
    "vampirism:pure_blood_0": { "burn_duration": 288000 },
    "vampirism:pure_blood_1": { "burn_duration": 432000 },
    "vampirism:pure_blood_2": { "burn_duration": 864000 },
    "vampirism:pure_blood_3": { "burn_duration": 1296000 },
    "vampirism:pure_blood_4": { "burn_duration": 1728000 }
  }
}

(108000 ticks = 90 minutes for purified garlic; pure blood 0–4 = 4, 6, 12, 18 and 24 hours.)

Add your own fuel, for example from another mod:

data/vampirism/data_maps/item/fog_diffuser_fuel.json (in your data pack)
{
  "values": {
    "mymod:dark_essence": { "burn_duration": 72000 }
  }
}

The API exposes the values as IGarlicDiffuserFuel / IFogDiffuserFuel (both extend IDiffuserFuel#burnDuration()) via VampirismDataMaps.GARLIC_DIFFUSER_FUEL and VampirismDataMaps.FOG_DIFFUSER_FUEL; see API reference.

Liquid color

vampirism:liquid_color assigns a colour to items so the alchemical cauldron can tint the liquid it shows when the item in its first slot is not a fluid container with a fluid tint of its own. The value is a plain integer containing the RGB colour (decimal, e.g. 0xBBBBBB = 12303291). If an item has no entry and no fluid, the cauldron falls back to 0x00003B.

data/vampirism/data_maps/item/liquid_color.json (generated default)
{
  "values": {
    "#c:crops/garlic": 12303291,
    "#c:crops/garlic/purified": 12303291,
    "#vampirism:holy_water": 6711039,
    "#vampirism:holy_water_splash": 6711039,
    "vampirism:pure_blood_0": 8128517,
    "vampirism:pure_blood_1": 8193283,
    "vampirism:pure_blood_2": 8585216,
    "vampirism:pure_blood_3": 8261134,
    "vampirism:pure_blood_4": 9306112
  }
}

Keys can be item ids or #item_tags.
