impl<'a> SystemParam for &'a Bundles
§type Item<'w, 's> = &'w Bundles
type Item<'w, 's> = &'w Bundles
The item type returned when constructing this system param.
The value of this associated type should be
Self
, instantiated with new lifetimes. Read moresource§fn init_state(_world: &mut World, _system_meta: &mut SystemMeta) -> Self::State
fn init_state(_world: &mut World, _system_meta: &mut SystemMeta) -> Self::State
Registers any
World
access used by this SystemParam
and creates a new instance of this param’s State
.source§unsafe fn get_param<'w, 's>(
_state: &'s mut Self::State,
_system_meta: &SystemMeta,
world: UnsafeWorldCell<'w>,

) -> Self::Item<'w, 's>
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
. Read moresource§unsafe fn new_archetype(
state: &mut Self::State,
archetype: &Archetype,
system_meta: &mut SystemMeta
)
unsafe fn new_archetype( state: &mut Self::State, archetype: &Archetype, system_meta: &mut SystemMeta )
For the specified
Archetype
, registers the components accessed by this SystemParam
(if applicable).a Read moresource§fn apply(state: &mut Self::State, system_meta: &SystemMeta, world: &mut World)
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 apply_deferred

state: &mut Self::State,
system_meta: &SystemMeta,
world: DeferredWorld<'_>
)
fn queue( state: &mut Self::State, system_meta: &SystemMeta, world: DeferredWorld<'_> )
Queues any deferred mutations to be applied at the next
apply_deferred
