Trait TriggerTargets

pub trait TriggerTargets {
    // Required methods
    fn components(&self) -> &[ComponentId];
    fn entities(&self) -> &[Entity];
}

Represents a collection of targets for a specific Trigger of an Event. Targets can be of type Entity or ComponentId.

When a trigger occurs for a given event and TriggerTargets, any Observer that watches for that specific event-target combination will run.

Required Methods

fn components(&self) -> &[ComponentId]

The components the trigger should target.

fn entities(&self) -> &[Entity]

The entities the trigger should target.
