[−]Trait oxygengine::prelude::shred::System
A System
, executed with a set of required Resource
s.
Associated Types
type SystemData: DynamicSystemData<'a>
The resource bundle required to execute this system.
You will mostly use a tuple of system data (which also implements
SystemData
). You can also create such a resource bundle by simply
deriving SystemData
for a struct.
Every SystemData
is also a DynamicSystemData
.
Required methods
fn run(&mut self, data: Self::SystemData)
Executes the system with the required system data.
Provided methods
fn running_time(&self) -> RunningTime
Returns a hint how long the system needs for running. This is used to optimize the way they're executed (might allow more parallelization).
Defaults to RunningTime::Average
.
fn accessor(&'b self) -> AccessorCow<'a, 'b, Self>
Return the accessor from the SystemData
.
fn setup(&mut self, world: &mut World)
Sets up the World
using Self::SystemData::setup
.
fn dispose(self, world: &mut World)
Performs clean up that requires resources from the World
.
This commonly removes components from world
which depend on external
resources.
