Node class - node library

Constructors

childCount → int: no setter
children → List<Node>: no setter
hashCode → int: The hash code for this object.
no setterinherited
isRenderable → bool: Whether this node contributes pixels during a render pass.
no setter
isTransparent → bool: Whether this node requires back-to-front alpha ordering.
no setter
localAabb → Aabb: Override to provide local-space bounding box.
no setter
localMatrix → Matrix4: Local transform matrix.
no setter
name ↔ String: getter/setter pair
ownWorldAabb → Aabb: Computes the AABB of this node's own geometry in world space (without descendants). Used for self-hits in raycasting and physics.
no setter
parent → Node?: no setter
pointable ↔ Pointable?: getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
transform → Transform3D: final
visible ↔ bool: getter/setter pair
worldAabb → Aabb: Computes the AABB of this node AND all its descendants in world space. Group nodes have no geometry, so their own box would be a phantom ±0.5m cube at their position — using it for culling wrongly discarded entire subtrees. The union is cached and invalidated on any transform or hierarchy change in the subtree.
no setter
worldMatrix → Matrix4: World transform matrix (accumulated from root).
no setter
worldPosition → Vector3: World position extracted from world matrix.
no setter

addChild(Node child) → void
collectVisible() → List<Node>: Collects all visible nodes in the tree.
findChild(String name) → Node?: Finds a child by name recursively.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onRender(Canvas canvas, Matrix4 viewProjection) → void: Override for custom rendering.
onTransformChanged() → void: Called when any transform property changes.
onUpdate(double dt) → void: Override for custom per-frame logic.
removeChild(Node child) → void
removeFromParent() → void
render(Canvas canvas, Matrix4 viewProjection) → void: Renders this node and children to the canvas.
toString() → String: A string representation of this object.
override
traverse(void visitor(Node child)) → void: Traverses the tree depth-first, calling visitor for each node.
update(double dt) → void: Called once per frame before rendering.
