pub struct RemovedComponentEvents { /* private fields */ }
Expand description
Stores the RemovedComponents
event buffers for all types of component in a given World
.
Implementations§
source§impl RemovedComponentEvents
impl RemovedComponentEvents
sourcepub fn new() -> RemovedComponentEvents
pub fn new() -> RemovedComponentEvents
Creates an empty storage buffer for component removal events.
sourcepub fn update(&mut self)
pub fn update(&mut self)
For each type of component, swaps the event buffers and clears the oldest event buffer. In general, this should be called once per frame/update.
sourcepub fn get(
&self,
component_id: impl Into<ComponentId>
) -> Option<&Events<RemovedComponentEntity>>
pub fn get( &self, component_id: impl Into<ComponentId> ) -> Option<&Events<RemovedComponentEntity>>
Gets the event storage for a given component.
sourcepub fn send(&mut self, component_id: impl Into<ComponentId>, entity: Entity)
pub fn send(&mut self, component_id: impl Into<ComponentId>, entity: Entity)
Sends a removal event for the specified component.
