Struct bevy::app::Main

pub struct Main;

The schedule that contains the app logic that is evaluated each tick of App::update().

By default, it will run the following schedules in the given order:

On the first run of the schedule (and only on the first run), it will run:

• PreStartup
• Startup
• PostStartup

Then it will run:

• First
• PreUpdate
• StateTransition
• RunFixedMainLoop
  • This will run FixedMain zero to many times, based on how much time has elapsed.
• Update
• PostUpdate
• Last

Rendering

Note rendering is not executed in the main schedule by default. Instead, rendering is performed in a separate SubApp which exchanges data with the main app in between the main schedule runs.

See RenderPlugin and PipelinedRenderingPlugin for more details.

Implementations

impl Main

pub fn run_main(world: &mut World, run_at_least_once: Local<'_, bool>)

A system that runs the “main schedule”

Trait Implementations

impl Clone for Main

fn clone(&self) -> Main

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Main

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for Main

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Main

fn eq(&self, other: &Main) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ScheduleLabel for Main

where Main: 'static + Send + Sync + Clone + Eq + Debug + Hash,

fn dyn_clone(&self) -> Box<dyn ScheduleLabel>

Clones this ScheduleLabel.

fn as_dyn_eq(&self) -> &(dyn DynEq + 'static)

Casts this value to a form where it can be compared with other type-erased values.

fn dyn_hash(&self, state: &mut dyn Hasher)

Feeds this value into the given Hasher.

fn intern(&self) -> Interned<dyn ScheduleLabel>

where Self: Sized,

Returns an Interned value corresponding to self.

impl Eq for Main

impl StructuralEq for Main

impl StructuralPartialEq for Main
