Struct bevy::prelude::SubApp

pub struct SubApp {
    pub update_schedule: Option<Interned<dyn ScheduleLabel>>,
    /* private fields */
}
Expand description

A secondary application with its own World. These can run independently of each other.

These are useful for situations where certain processes (e.g. a render thread) need to be kept separate from the main application.

§Example


#[derive(Resource, Default)]
struct Val(pub i32);

#[derive(Debug, Clone, Copy, Hash, PartialEq, Eq, AppLabel)]
struct ExampleApp;

// Create an app with a certain resource.
let mut app = App::new();
app.insert_resource(Val(10));

// Create a sub-app with the same resource and a single schedule.
let mut sub_app = SubApp::new();
sub_app.insert_resource(Val(100));

// Setup an extract function to copy the resource's value in the main world.
sub_app.set_extract(|main_world, sub_world| {
    sub_world.resource_mut::<Val>().0 = main_world.resource::<Val>().0;
});

// Schedule a system that will verify extraction is working.
sub_app.add_systems(Main, |counter: Res<Val>| {
    // The value will be copied during extraction, so we should see 10 instead of 100.
    assert_eq!(counter.0, 10);
});

// Add the sub-app to the main app.
app.insert_sub_app(ExampleApp, sub_app);

// Update the application once (using the default runner).
app.run();

Fields§

§update_schedule: Option<Interned<dyn ScheduleLabel>>

The schedule that will be run by update.

Implementations§

pub fn update(&mut self)

Runs the default schedule.

pub fn extract(&mut self, world: &mut World)

Extracts data from world into the app’s world using the registered extract method.

Note: There is no default extract method. Calling extract does nothing if set_extract has not been called.

pub fn set_extract<F>(&mut self, extract: F) -> &mut SubApp
where F: Fn(&mut World, &mut World) + Send + 'static,

Sets the method that will be called by extract.

The first argument is the World to extract data from, the second argument is the app World.
