Enum TimeUpdateStrategy 

pub enum TimeUpdateStrategy {
    Automatic,
    ManualInstant(Instant),
    ManualDuration(Duration),
    FixedTimesteps(u32),
}

Configuration resource used to determine how the time system should run.

For most cases, TimeUpdateStrategy::Automatic is fine. When writing tests, dealing with networking or similar, you may prefer to set the next Time value manually.

Variants

Automatic

Time will be automatically updated each frame using an Instant sent from the render world. If nothing is sent, the system clock will be used instead. See TimeSender for more details.

ManualInstant(Instant)

Time will be updated to the specified Instant value each frame. In order for time to progress, this value must be manually updated each frame.

Note that the Time resource will not be updated until TimeSystems runs.

ManualDuration(Duration)

Time will be incremented by the specified Duration each frame.

FixedTimesteps(u32)

Time will be incremented by the fixed timestep each frame, multiplied by the specified factor n. This means that a call to App::update will always run the fixed loop exactly n times.

Trait Implementations

impl Component for TimeUpdateStrategy

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::SparseSet

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn map_entities<M: EntityMapper>(this: &mut Self, mapper: &mut M)

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns ComponentRelationshipAccessor required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

impl Default for TimeUpdateStrategy

fn default() -> TimeUpdateStrategy

Returns the “default value” for a type.
