Struct StatEntities 

pub struct StatEntities<'w, 's, Q: QualifierFlag> { /* private fields */ }

A root SystemParam that curates all entities marked as StatEntity.

Join with StatStreams via StatEntities::join to start querying.

Implementations

impl<'w, 's, Q: QualifierFlag> StatEntities<'w, 's, Q>

pub fn join<'t, S: StatStream<Qualifier = Q>>( &'t self, stream: S, ) -> JoinedQuerier<'w, 's, 't, Q, S>

Trait Implementations

impl<'w, 's, Q: Debug + QualifierFlag> Debug for StatEntities<'w, 's, Q>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Q: QualifierFlag> SystemParam for StatEntities<'_, '_, Q>

type State = FetchState<Q>

Used to store data which persists across invocations of a system.

type Item<'w, 's> = StatEntities<'w, 's, Q>

The item type returned when constructing this system param. The value of this associated type should be Self, instantiated with new lifetimes.

fn init_state(world: &mut World) -> Self::State

Creates a new instance of this param’s State.

fn init_access( state: &Self::State, system_meta: &mut SystemMeta, component_access_set: &mut FilteredAccessSet, world: &mut World, )

Registers any World access used by this SystemParam

fn apply(state: &mut Self::State, system_meta: &SystemMeta, world: &mut World)

Applies any deferred mutations stored in this SystemParam’s state. This is used to apply Commands during ApplyDeferred.

fn queue( state: &mut Self::State, system_meta: &SystemMeta, world: DeferredWorld<'_>, )

Queues any deferred mutations to be applied at the next ApplyDeferred.

unsafe fn validate_param<'w, 's>( state: &'s mut Self::State, _system_meta: &SystemMeta, _world: UnsafeWorldCell<'w>, ) -> Result<(), SystemParamValidationError>

Validates that the param can be acquired by the get_param.

unsafe fn get_param<'w, 's>( state: &'s mut Self::State, system_meta: &SystemMeta, world: UnsafeWorldCell<'w>, change_tick: Tick, ) -> Self::Item<'w, 's>

Creates a parameter to be passed into a SystemParamFunction.

where Option<Res<'w, GlobalStatDefaults>>: ReadOnlySystemParam, Option<Res<'w, GlobalStatRelations<Q>>>: ReadOnlySystemParam, Query<'w, 's, Entity, With<StatEntity>>: ReadOnlySystemParam,
