A condition that must be met for a loot entry or pool to apply.

Variants

SurvivesExplosion

The loot survives explosion damage (random chance based on explosion radius). Vanilla: 1/radius chance to pass. If no explosion, always passes.

BlockStateProperty

Check block state properties match expected values.

Fields

block: Identifier

properties: &'static [PropertyCheck]

RandomChance(f32)

Simple random chance (0.0 to 1.0).

RandomChanceWithEnchantedBonus

Random chance affected by an enchantment (e.g., looting). Vanilla 1.21+: uses enchanted_chance which can be constant or linear.

Fields

enchantment: Identifier

unenchanted_chance: f32

enchanted_chance: EnchantedChance

For linear formula: chance = base + per_level * (level - 1)

MatchTool(ToolPredicate)

Match tool predicate - checks if the tool matches certain criteria.

TableBonus

Table bonus condition - chance based on enchantment level from a table. The chances array is indexed by enchantment level (0 = no enchant, 1 = level 1, etc.)

Fields

enchantment: Identifier

chances: &'static [f32]

Inverted(&'static LootCondition)

Inverted condition - passes if the inner condition fails.

AnyOf(&'static [LootCondition])

Any of the conditions pass (OR logic).

AllOf(&'static [LootCondition])

All of the conditions pass (AND logic).

KilledByPlayer

Killed by player condition.

EntityProperties

Entity properties condition - checks entity predicates.

Fields

entity: LootContextEntity

predicate: EntityPredicate

DamageSourceProperties

Damage source properties condition - checks how the entity was damaged.

Fields

predicate: DamageSourcePredicate

LocationCheck

Location check condition - checks the location predicate.

Fields

offset_x: i32

offset_y: i32

offset_z: i32

predicate: LocationPredicate

WeatherCheck

Weather check condition - checks current weather.

Fields

raining: Option<bool>

thundering: Option<bool>

TimeCheck

Time check condition - checks game time.

Fields

value: NumberProviderRange

period: Option<i64>

ValueCheck

Value check condition - compares a number provider value against a range.

Fields

value: NumberProvider

range: NumberProviderRange

EnchantmentActiveCheck

Check if a specific enchantment is active.

Fields

enchantment: Identifier

active: bool

EntityScores

Check entity scoreboard scores.

Fields

entity: LootContextEntity

scores: &'static [(&'static str, NumberProviderRange)]

Reference(Identifier)

Reference to a named condition in the registry.
