Shorthand for App.draw.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
id → int
Per-type unique identifier, auto-assigned in the constructor.
no setterinherited
input → InputSystem<T>
Shorthand for App.input.
no setterinherited
isStopped → bool
Whether propagation has been halted via stopPropagation.
no setterinherited
name ↔ String
Human-readable name, defaults to <runtimeType>_<id>.
getter/setter pairinherited
namedId → String
Per-type unique String identifier, auto-assigned in the constructor. Defaults to <runtimeType>_<id>.
no setterinherited
normal → Vector2D
final
origin ↔ ECSBase<T>?
The node that originally emitted this event.
getter/setter pairinherited
parent ↔ ECSBase<T>?
The parent object in the ECS tree, if any.
getter/setter pairinherited
penetration → double
final
priority ↔ int
Relative ordering priority used when processing queued events. Events with lower priority values are processed first.
getter/setter pairinherited
renderer → Renderer<T>
Shorthand for App.renderer.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scene → Scene<T>

no setterinherited
sceneBounds → Bounds
no setterinherited
sceneHeight → double
no setterinherited
sceneSize → Vector2D
no setterinherited
sceneWidth → double
no setterinherited
scope ↔ EventScope?
How far this event should propagate.
getter/setter pairinherited
screenHeight → double
Shorthand for App's height.
no setterinherited
screenSize → Vector2D
Shorthand for App.screenSize.
no setterinherited
screenWidth → double
Shorthand for App's width.
no setterinherited
self → Event<T>
This object cast to T.

simTime ↔ double
getter/setter pairinherited
time → AppTime<T>
Shorthand for App.time.

Methods

as<A extends E, B extends E>() → (A, B)?
Returns the pair typed as (A, B) if the collision is between an A and a B (in either order), or null if neither ordering matches.
inherited
asHas<A extends E, B extends Comp<T>, C extends E, D extends Comp<T>>() → (A, C)?
Returns the pair typed as (A, C) only if the types match (A/C) and the corresponding components are present (B on the first, D on the second).
inherited
callback(void callback()) → void
inherited
getAncestors() → Iterable<ECSBase<T>>
Returns every ancestor of this component, from immediate parent up to the root.
inherited
getDepth() → int
Returns the depth/level in the hierarchy.
inherited
getParentAs<P extends ECSBase<T>>() → P?
Returns parent cast to P, or null if the cast would fail.
inherited
getPath() → List<ECSBase<T>>
Returns the path from the root down to this one, inclusive.
inherited
has<A extends Comp<T>, B extends Comp<T>>() → (Entity<T>, Entity<T>)?
Returns the pair ordered so that the first element carries component A and the second carries component B, or null if the collision doesn't involve both component types.
inherited
hasParentOf<P extends ECSBase<T>>() → bool
Whether parent is of type P.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onSelf(void fn(Event<T> self)) → Event<T>
Calls fn with self and returns self, for fluent chaining.
inherited
run(Task<T> task) → void
inherited
Links this event to link so that stopping propagation on one (via stopPropagation) also stops the other.
inherited
stopPropagation() → void
Halts further propagation of this event (and any event linked via setLink). Already-visited nodes are unaffected; only handlers further down the propagation chain are skipped.
inherited
task(Task<T> task) → void
inherited
toString() → String
A string representation of this object.
inherited
uniqKey(String key) → String
Returns a key namespaced to this object's namedId.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
