Struct LootContext

    pub rng: &'a mut R,
    pub luck: f32,
    pub block_state: Option<BlockStateId>,
    pub tool: Option<&'a ItemStack>,

    pub damage_source: Option<DamageSourceInfo<'a>>,
    pub block_entity: Option<BlockEntityRef<'a>>,
    pub interacting_entity: Option<EntityRef<'a>>,
}

Context for loot table evaluation, containing all relevant game state.

This mirrors vanilla’s LootContext / LootParams system.

Fields

rng: &'a mut R

Random number generator.

luck: f32

Luck value (e.g., from Luck of the Sea enchantment).

block_state: Option<BlockStateId>

The block state being broken (for block loot tables).

tool: Option<&'a ItemStack>

The tool used to break the block.

explosion_radius: Option<f32>

Explosion radius if caused by an explosion.

killed_by_player: bool

Whether the entity was killed by a player.

origin: Option<(f64, f64, f64)>

World position where the loot is generated (block position or entity death location).

game_time: Option<i64>

Current game time in ticks (for TimeCheck condition).

weather: Option<WeatherState>

Current weather state.

this_entity: Option<EntityRef<'a>>

The entity being looted (the killed mob, block entity owner, etc.). This is a type-erased pointer; actual entity data depends on game implementation.

killer_entity: Option<EntityRef<'a>>

The entity that killed this_entity (for mob loot tables).

direct_killer_entity: Option<EntityRef<'a>>

The direct attacker entity (e.g., arrow, not the player who shot it).

last_damage_player: Option<EntityRef<'a>>

The player who dealt the final damage (may be different from killer).

damage_source: Option<DamageSourceInfo<'a>>

Damage source information for entity deaths.

block_entity: Option<BlockEntityRef<'a>>

Block entity reference for container/block loot.

interacting_entity: Option<EntityRef<'a>>

The entity interacting with a block/entity (e.g., player opening a chest).
