Resource for controlling system stepping behavior

Implementations§

§

impl Stepping

pub fn new() -> Stepping

Create a new instance of the Stepping resource.

pub fn begin_frame(stepping: Option<ResMut<'_, Stepping>>)

System to call denoting that a new render frame has begun

Note: This system is automatically added to the default MainSchedule.

pub fn schedules(&self) -> Result<&Vec<Interned<dyn ScheduleLabel>>, NotReady>

Return the list of schedules with stepping enabled in the order they are executed in.

pub fn cursor(&self) -> Option<(Interned<dyn ScheduleLabel>, NodeId)>

Return our current position within the stepping frame

NOTE: This function will return None during normal execution with stepping enabled. This can happen at the end of the stepping frame after the last system has been run, but before the start of the next render frame.

pub fn add_schedule(&mut self, schedule: impl ScheduleLabel) -> &mut Stepping

Enable stepping for the provided schedule

pub fn remove_schedule(&mut self, schedule: impl ScheduleLabel) -> &mut Stepping

Disable stepping for the provided schedule

NOTE: This function will also clear any system-specific behaviors that may have been configured.

pub fn clear_schedule(&mut self, schedule: impl ScheduleLabel) -> &mut Stepping

Clear behavior set for all systems in the provided Schedule

pub fn enable(&mut self) -> &mut Stepping

Begin stepping at the start of the next frame

pub fn disable(&mut self) -> &mut Stepping

Disable stepping, resume normal systems execution

pub fn is_enabled(&self) -> bool

Check if stepping is enabled

pub fn step_frame(&mut self) -> &mut Stepping

Run the next system during the next render frame

NOTE: This will have no impact unless stepping has been enabled

pub fn continue_frame(&mut self) -> &mut Stepping

Run all remaining systems in the stepping frame during the next render frame

NOTE: This will have no impact unless stepping has been enabled

pub fn always_run<Marker>( &mut self, schedule: impl ScheduleLabel, system: impl IntoSystem<(), (), Marker>, ) -> &mut Stepping

Ensure this system always runs when stepping is enabled

Note: if the system is run multiple times in the Schedule, this will apply for all instances of the system.

pub fn always_run_node( &mut self, schedule: impl ScheduleLabel, node: NodeId, ) -> &mut Stepping

Ensure this system instance always runs when stepping is enabled

pub fn never_run<Marker>( &mut self, schedule: impl ScheduleLabel, system: impl IntoSystem<(), (), Marker>, ) -> &mut Stepping

Ensure this system never runs when stepping is enabled

pub fn never_run_node( &mut self, schedule: impl ScheduleLabel, node: NodeId, ) -> &mut Stepping

Ensure this system instance never runs when stepping is enabled

pub fn set_breakpoint<Marker>( &mut self, schedule: impl ScheduleLabel, system: impl IntoSystem<(), (), Marker>, ) -> &mut Stepping

Add a breakpoint for system

pub fn set_breakpoint_node( &mut self, schedule: impl ScheduleLabel, node: NodeId, ) -> &mut Stepping

Add a breakpoint for system instance

pub fn clear_breakpoint<Marker>( &mut self, schedule: impl ScheduleLabel, system: impl IntoSystem<(), (), Marker>, ) -> &mut Stepping

Clear a breakpoint for the system

pub fn clear_breakpoint_node( &mut self, schedule: impl ScheduleLabel, node: NodeId, ) -> &mut Stepping

clear a breakpoint for system instance

pub fn clear_system<Marker>( &mut self, schedule: impl ScheduleLabel, system: impl IntoSystem<(), (), Marker>, ) -> &mut Stepping

Clear any behavior set for the system

pub fn clear_node( &mut self, schedule: impl ScheduleLabel, node: NodeId, ) -> &mut Stepping

clear a breakpoint for system instance

pub fn skipped_systems(&mut self, schedule: &Schedule) -> Option<FixedBitSet>

get the list of systems this schedule should skip for this render frame
