Enum bevy::asset::AssetEvent

pub enum AssetEvent<A>
where
    A: Asset,
{
    Added {
        id: AssetId<A>,
    },
    Modified {
        id: AssetId<A>,
    },
    Removed {

    Unused {
        id: AssetId<A>,
    },
    LoadedWithDependencies {
        id: AssetId<A>,
    },
}

Events that occur for a specific loaded Asset, such as “value changed” events and “dependency” events.

Variants

Added

Emitted whenever an Asset is added.

Fields

id: AssetId<A>

Modified

Emitted whenever an Asset value is modified.

Fields

id: AssetId<A>

Removed

Emitted whenever an Asset is removed.

Fields

id: AssetId<A>

Unused

Emitted when the last super::Handle::Strong of an Asset is dropped.

Fields

id: AssetId<A>

LoadedWithDependencies

Emitted whenever an Asset has been fully loaded (including its dependencies and all “recursive dependencies”).

Fields

id: AssetId<A>

Implementations

impl<A> AssetEvent<A>

where A: Asset,

pub fn is_loaded_with_dependencies( &self, asset_id: impl Into<AssetId<A>> ) -> bool

Returns true if this event is AssetEvent::LoadedWithDependencies and matches the given id.

fn check_textures(
    mut next_state: ResMut<NextState<AppState>>,
    rpg_sprite_folder: Res<RpgSpriteFolder>,
    mut events: EventReader<AssetEvent<LoadedFolder>>,
) {
    // Advance the `AppState` once all sprite handles have been loaded by the `AssetServer`
    for event in events.read() {
        if event.is_loaded_with_dependencies(&rpg_sprite_folder.0) {
            next_state.set(AppState::Finished);
        }
    }
}

pub fn is_added(&self, asset_id: impl Into<AssetId<A>>) -> bool

Returns true if this event is AssetEvent::Added and matches the given id.

pub fn is_modified(&self, asset_id: impl Into<AssetId<A>>) -> bool

Returns true if this event is AssetEvent::Modified and matches the given id.

pub fn is_removed(&self, asset_id: impl Into<AssetId<A>>) -> bool

Returns true if this event is AssetEvent::Removed and matches the given id.

pub fn is_unused(&self, asset_id: impl Into<AssetId<A>>) -> bool

Returns true if this event is AssetEvent::Unused and matches the given id.

Trait Implementations

impl<A> Clone for AssetEvent<A>

where A: Asset,

fn clone(&self) -> AssetEvent<A>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A> Debug for AssetEvent<A>

where A: Asset,

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

Formats the value using the given formatter.

impl<A> PartialEq for AssetEvent<A>

where A: Asset,

fn eq(&self, other: &AssetEvent<A>) -> 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.
