RectAreaLightComponent class Scene graph

An engine Component that places a RectAreaLight in the scene.

The rectangle lies in the owning node's local XY plane and emits along local +Z; the node's world transform positions and aims it.

Constructors

RectAreaLightComponent(RectAreaLight light): Creates a component that lights the scene with light.

enabled ↔ bool: Whether this component's update hook runs each frame.
getter/setter pairinherited
hashCode → int: The hash code for this object.
no setterinherited
isAttached → bool: Whether this component is currently attached to a node.
no setterinherited
isLoaded → bool: Whether onLoad has completed.
no setterinherited
isMounted → bool: Whether the owning node is part of a live scene graph.
no setterinherited
light ↔ RectAreaLight: The light this component contributes.
getter/setter pair
node → Node: The node this component is attached to.
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
worldPosition → Vector3: The panel center: the owning node's world-space translation.
no setter
worldRight → Vector3: The panel's world-space width axis (the node's rotated local +X), unit length.
no setter
worldUp → Vector3: The panel's world-space height axis (the node's rotated local +Y), unit length.
no setter

cloneFor(Node cloneOwner) → Component?: Clones carry the light, sharing the light object like other clone payloads (geometry, materials).
override
fixedUpdate(double fixedDt) → void: Called once per fixed physics step while the component is mounted, enabled, and loaded. fixedDt is the fixed timestep of the surrounding PhysicsWorld, not the frame interval.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onAttach() → void: Called when this component is added to a node.
inherited
onDetach() → void: Called when this component is removed from a node.
inherited
onLoad() → Future<void>: Optional asynchronous setup, such as loading an asset.
inherited
onMount() → void: Called when the owning node enters a live scene graph.
override
onUnmount() → void: Called when the owning node leaves a live scene graph.
override
toString() → String: A string representation of this object.
inherited
update(double deltaSeconds) → void: Called once per frame while the component is mounted, enabled, and loaded. deltaSeconds is the elapsed time since the previous tick. A traversal visits each component at most once. Removing this component or an earlier sibling is safe. A component inserted before the current traversal position starts on the next frame. Reordering component or child lists during traversal is unsupported.
