Struct DamageHistory 

pub struct DamageHistory {
    records: SyncMutex<FxHashMap<EntityGeneration, DamageRecord>>,
}

Server-owned equivalent of vanilla’s per-entity lastDamageSource fields.

Entities and worlds link back weakly. Records retain the victim’s clock, which has no world back-reference, to avoid cycles through the victim or world. Only gameplay-owned victims retain strong sources. Removal downgrades their own record; an ownership sweep also covers disconnects and manager teardown.

Fields

records: SyncMutex<FxHashMap<EntityGeneration, DamageRecord>>

Implementations

impl DamageHistory

pub(crate) fn record( self: &Arc<Self>, victim: &EntityBase, source: &DamageSource, clock: &Arc<GameTime>, )

pub(crate) fn last_damage_source( &self, victim: EntityGeneration, ) -> Option<RecentDamageSource>

pub(crate) fn clear_victim(&self, victim: EntityGeneration)

pub(crate) fn expire(&self)

Releases expired records and strong sources with no gameplay owner. Runs while frozen too; expiry still uses the unchanged gameplay clock.

pub(crate) fn clear(&self)

Releases history ownership after gameplay work has stopped.
