impl SystemStagesBuilder

pub fn with_core_stages() -> SystemStagesBuilder

Create a SystemStagesBuilder for SystemStages collection, initialized with a stage for each CoreStage.

pub fn finish(self) -> SystemStages

Finish building and convert to SystemStages

pub fn from_stages(stages: SystemStages) -> SystemStagesBuilder

pub fn add_startup_system<Args, S>( &mut self, system: S, ) -> &mut SystemStagesBuilder
where S: IntoSystem<Args, (), (), Sys = StaticSystem<(), ()>>,

Add a system that will run only once, before all of the other non-startup systems. If wish to reset session and run again, can modify SessionStarted resource in world.

pub fn add_single_success_system<Args, S>( &mut self, system: S, ) -> &mut SystemStagesBuilder
where S: IntoSystem<Args, (), Option<()>, Sys = StaticSystem<(), Option<()>>>,

Add a system that will run each frame until it succeeds (returns Some). Runs before all stages. Uses Option to allow for easy usage of ?.

pub fn add_system_to_stage<Args, S>( &mut self, label: impl StageLabel, system: S, ) -> &mut SystemStagesBuilder
where S: IntoSystem<Args, (), (), Sys = StaticSystem<(), ()>>,

Add a System to the stage with the given label.

pub fn insert_stage_before<L, S>( &mut self, label: L, stage: S, ) -> &mut SystemStagesBuilder
where L: StageLabel, S: SystemStage + 'static,

Insert a new stage, before another existing stage

pub fn insert_stage_after<L, S>( &mut self, label: L, stage: S, ) -> &mut SystemStagesBuilder
where L: StageLabel, S: SystemStage + 'static,

Insert a new stage, after another existing stage

pub fn insert_startup_resource<T>(&mut self, resource: T)
where T: HasSchema,

Insert a startup resource. On stage / session startup (first step), will be inserted into World.

If already exists, will be overwritten.

pub fn init_startup_resource<T>(&mut self) -> RefMut<'_, T>
where T: HasSchema + Default,

Init startup resource with default, and return mutable ref for modification. If already exists, returns mutable ref to existing resource.

pub fn startup_resource_mut<T>(&self) -> Option<RefMut<'_, T>>
where T: HasSchema,

Get mutable reference to startup resource if found.
