Expand description
A parameter that can be used in a System
.
§Derive
This trait can be derived with the super::SystemParam
macro.
This macro only works if each field on the derived struct implements SystemParam
.
Note: There are additional requirements on the field types.
See the Generic SystemParam
s section for details and workarounds of the probable
cause if this derive causes an error to be emitted.
Derived SystemParam
structs may have two lifetimes: 'w
for data stored in the World
,
and 's
for data stored in the parameter’s state.
The following list shows the most common SystemParam
s and which lifetime they require
Query<'w, 's, Entity>,
Res<'w, SomeResource>,
ResMut<'w, SomeOtherResource>,
Local<'s, u8>,
Commands<'w, 's>,
EventReader<'w, 's, SomeEvent>,
EventWriter<'w, SomeEvent>
§PhantomData
PhantomData
is a special type of SystemParam
that does nothing.
This is useful for constraining generic types or lifetimes.
§Example
use std::marker::PhantomData;
use bevy_ecs::system::SystemParam;
#[derive(SystemParam)]
struct MyParam<'w, Marker: 'static> {
foo: Res<'w, SomeResource>,
marker: PhantomData<Marker>,
}
fn my_system<T: 'static>(param: MyParam<T>) {
// Access the resource through `param.foo`
}
§Generic SystemParam
s
When using the derive macro, you may see an error in the form of:
expected ... [ParamType]
found associated type `<[ParamType] as SystemParam>::Item<'_, '_>`
where [ParamType]
is the type of one of your fields.
To solve this error, you can wrap the field of type [ParamType]
with StaticSystemParam
(i.e. StaticSystemParam<[ParamType]>
).
§Details
The derive macro requires that the SystemParam
implementation of
each field F
’s Item
’s is itself F
(ignoring lifetimes for simplicity).
This assumption is due to type inference reasons, so that the derived SystemParam
can be
used as an argument to a function system.
If the compiler cannot validate this property for [ParamType]
, it will error in the form shown above.
This will most commonly occur when working with SystemParam
s generically, as the requirement
has not been proven to the compiler.
§Safety
The implementor must ensure the following is true.
SystemParam::init_state
correctly registers allWorld
accesses used bySystemParam::get_param
with the providedsystem_meta
.- None of the world accesses may conflict with any prior accesses registered
on
system_meta
.
Required Associated Types§
sourcetype State: Send + Sync + 'static
type State: Send + Sync + 'static
Used to store data which persists across invocations of a system.
sourcetype Item<'world, 'state>: SystemParam<State = Self::State>
type Item<'world, 'state>: SystemParam<State = Self::State>
The item type returned when constructing this system param.
The value of this associated type should be Self
, instantiated with new lifetimes.
You could think of SystemParam::Item<'w, 's>
as being an operation that changes the lifetimes bound to Self
.
Required Methods§
sourcefn 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
.
sourceunsafe fn get_param<'world, 'state>(
state: &'state mut Self::State,
system_meta: &SystemMeta,
world: UnsafeWorldCell<'world>,
change_tick: Tick
) -> Self::Item<'world, 'state>
unsafe fn get_param<'world, 'state>( state: &'state mut Self::State, system_meta: &SystemMeta, world: UnsafeWorldCell<'world>, change_tick: Tick ) -> Self::Item<'world, 'state>
Creates a parameter to be passed into a SystemParamFunction
.
§Safety
- The passed
UnsafeWorldCell
must have access to any world data registered ininit_state
. world
must be the sameWorld
that was used to initializestate
.
Provided Methods§
sourceunsafe 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
§Safety
archetype
must be from the World
used to initialize state
in init_state
.
sourcefn 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
.
sourcefn queue(
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
.
