Struct EntityData 

pub struct EntityData<T> { /* private fields */ }

A value kept on each entity, by uuid, at its key (the mod’s own: <mod>:<key>); its default where the entity has none yet.

static HITS: EntityData<u32> = EntityData::new("hits");
HITS.with_mut(&damage.uuid, |n| *n += 1);

Implementations

impl<T: Schema + Default> EntityData<T>

pub const fn new(key: &'static str) -> Self

Saved with the entity.

pub const fn session(key: &'static str) -> Self

Kept while the entity is loaded, not saved (a Yog Script member synced and not saved).

pub fn with<R>(&self, uuid: &str, read: impl FnOnce(&T) -> R) -> R

What read makes of entity uuid’s value: the server’s where it runs here, else what this client was sent.

pub fn with_mut<R>(&self, uuid: &str, change: impl FnOnce(&mut T) -> R) -> R

Entity uuid’s value changed by change, and set (server side: sent to the players who see it by the tick’s end).
