Implementations§
§impl SystemStagesBuilder
impl SystemStagesBuilder
pub fn with_core_stages() -> 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
pub fn finish(self) -> SystemStages
Finish building and convert to SystemStages
pub fn from_stages(stages: SystemStages) -> SystemStagesBuilder
pub fn from_stages(stages: SystemStages) -> SystemStagesBuilder
Create SystemStagesBuilder
by taking existing SystemStages
.
pub fn add_startup_system<Args, S>(
&mut self,
system: S,
) -> &mut SystemStagesBuilder
pub fn add_startup_system<Args, S>( &mut self, system: S, ) -> &mut SystemStagesBuilder
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
pub fn add_single_success_system<Args, S>( &mut self, system: S, ) -> &mut SystemStagesBuilder
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
pub fn add_system_to_stage<Args, S>( &mut self, label: impl StageLabel, system: S, ) -> &mut SystemStagesBuilder
Add a System
to the stage with the given label.
pub fn insert_stage_before<L, S>(
&mut self,
label: L,
stage: S,
) -> &mut SystemStagesBuilderwhere
L: StageLabel,
S: SystemStage + 'static,
pub fn insert_stage_before<L, S>(
&mut self,
label: L,
stage: S,
) -> &mut SystemStagesBuilderwhere
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 SystemStagesBuilderwhere
L: StageLabel,
S: SystemStage + 'static,
pub fn insert_stage_after<L, S>(
&mut self,
label: L,
stage: S,
) -> &mut SystemStagesBuilderwhere
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,
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>
pub fn init_startup_resource<T>(&mut self) -> RefMut<'_, T>
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,
pub fn startup_resource_mut<T>(&self) -> Option<RefMut<'_, T>>where
T: HasSchema,
Get mutable reference to startup resource if found.
