Armor and protection

These maps hold 1.7’s HazmatRegistry, ArmorRegistry, ArmorUtil and DamageResistanceHandler tables. The overview explains the file format.

radiation_resistance

data/hbm/value_maps/item/radiation_resistance.json. Registry: item. HBM ships 124 entries.

Value: a double. The worn pieces’ values are added up, and incoming radiation is multiplied by 10^-sum. HBM’s values for a set are 1.7’s set value split by slot: helmet 0.2, chestplate 0.4, leggings 0.3, boots 0.1 of the total.

{
  "values": {
    "hbm:ajr_helmet": 0.26,
    "hbm:ajr_plate": 0.52,
    "hbm:ajr_legs": 0.39,
    "hbm:ajr_boots": 0.13
  }
}

Example: a full set with a total of 2.0 lets through 1% of radiation.

protection_classes

data/hbm/value_maps/item/protection_classes.json. Registry: item. HBM ships 32 entries.

What a helmet, a gas mask filter or an armor module protects against. Value: a list of protection class names. HBM’s classes are GAS_LUNG, GAS_MONOXIDE, GAS_INERT, PARTICLE_COARSE, PARTICLE_FINE, BACTERIA, NERVE_AGENT, GAS_BLISTERING, SAND and LIGHT; addon mods may add more. Fluid toxins and other hazards name these classes (see toxin).

{
  "values": {
    "hbm:ajr_helmet": ["PARTICLE_COARSE", "PARTICLE_FINE", "GAS_LUNG", "BACTERIA", "GAS_BLISTERING", "GAS_MONOXIDE", "LIGHT", "SAND"]
  }
}

A gas mask’s protection comes from its installed filter; the filter item is the one that needs the entry.

faraday_armor

data/hbm/value_maps/item/faraday_armor.json. Registry: item. HBM ships no entries.

Value: a boolean. Whether a piece is conductive (“Faraday”) armor. For items without an entry, HBM keeps 1.7’s rule, which looks for metal names in the item’s id. true or false here overrides that rule.

{
  "values": {
    "othermod:copper_chestplate": true
  }
}

armor_sets

data/hbm/value_maps/item/armor_sets.json. Registry: item. HBM ships 34 entries.

Full four-piece sets, keyed by the chestplate.

Field	Type	Default	Meaning
`helmet`	item id	none	The set’s helmet. Absent: the helmet slot must be empty.
`legs`	item id	none	The set’s leggings. Absent: that slot must be empty.
`boots`	item id	none	The set’s boots. Absent: that slot must be empty.
`checks`	list of strings	empty	The set checks the full set passes: `hazmat`, `hazmat2`, `digamma`, `asbestos`.
`resistance`	resistance stats	none	The full set’s damage resistance (format below).

The checks are 1.7’s full-set tests: hazmat (a full hazmat set, needed against full_body fluid toxins, mud, cold items and more), hazmat2 (heavy hazmat), digamma (digamma protection) and asbestos (protection from the thermal blast).

{
  "values": {
    "hbm:asbestos_plate": {
      "helmet": "hbm:asbestos_helmet",
      "legs": "hbm:asbestos_legs",
      "boots": "hbm:asbestos_boots",
      "checks": ["asbestos"],
      "resistance": { "category": { "FIRE": { "threshold": 10.0, "resistance": 0.9 } } }
    }
  }
}

damage_resistance (items)

data/hbm/value_maps/item/damage_resistance.json. Registry: item. HBM ships 2 entries.

One piece’s damage resistance, whether worn alone or as part of a set. Value: resistance stats.

{
  "values": {
    "hbm:jackt": { "category": { "PHYS": { "threshold": 1.0, "resistance": 0.2 } } },
    "hbm:jackt2": { "category": { "PHYS": { "threshold": 2.0, "resistance": 0.25 } } }
  }
}

damage_resistance (entity types)

data/hbm/value_maps/entity_type/damage_resistance.json. Registry: entity type. HBM ships 2 entries.

An entity’s own damage resistance. Value: resistance stats.

{
  "values": {
    "minecraft:creeper": { "category": { "EXPL": { "threshold": 2.0, "resistance": 0.25 } } },
    "hbm:entity_mob_nuclear_creeper": { "category": { "EXPL": { "threshold": 5.0, "resistance": 0.35 } } }
  }
}

Resistance stats

The format shared by armor_sets’ resistance and both damage_resistance maps:

{
  "category": { "PHYS": { "threshold": 4.0, "resistance": 0.15 }, "EXPL": { "threshold": 7.5, "resistance": 0.25 } },
  "exact": { "fall": { "resistance": 1.0 } },
  "other": { "resistance": 0.15 }
}

Field	Meaning
`category`	By damage category: `EXPL` (explosions), `FIRE`, `PHYS` (projectiles, cactus and anything an entity deals), `EN` (lasers, plasma, microwave, subatomic, electric).
`exact`	By damage type message id (`fall`, `drown`, an addon mod’s own type). For bullet damage `bullet_x`, an entry for `x` also matches.
`other`	Any other damage that armor can block.

Each entry is {"threshold", "resistance"}, both floats defaulting to 0. For one hit, exact is checked first, then category, then other. Damage at or below the threshold is blocked entirely; above it, the threshold is subtracted and the rest is multiplied by 1 - resistance. A resistance of 1.0 blocks the damage completely. The worn set, the worn pieces and the entity’s own stats are added together. Some weapons pierce part of the threshold and resistance.

lockpick_jacket

data/hbm/value_maps/item/lockpick_jacket.json. Registry: item. HBM ships 2 entries.

Value: a boolean. A chestplate with true multiplies the chance to pick a lock a hundredfold.

{
  "values": {
    "hbm:jackt": true,
    "hbm:jackt2": true
  }
}
