pub struct SystemBuilder<'w, T: SystemParam = ()> { /* private fields */ }
Expand description

Builder struct used to construct state for SystemParam passed to a system.


fn my_system(res: Res<R>, query: Query<&A>, param: MyParam) {
    // ...
}

// Create a builder from the world, helper methods exist to add `SystemParam`,
// alternatively use `.param::<T>()` for any other `SystemParam` types.
let system = SystemBuilder::<()>::new(&mut world)
    .resource::<R>()
    .query::<&A>()
    .param::<MyParam>()
    .build(my_system);

// Parameters that the builder is initialised with will appear first in the arguments.
let system = SystemBuilder::<(Res<R>, Query<&A>)>::new(&mut world)
    .param::<MyParam>()
    .build(my_system);

// Parameters that implement `BuildableSystemParam` can use `.builder::<T>()` to build in place.
let system = SystemBuilder::<()>::new(&mut world)
    .resource::<R>()
    .builder::<Query<&A>>(|builder| { builder.with::<B>(); })
    .param::<MyParam>()
    .build(my_system);

world.run_system_once(system);
