Node class
Base node in the scene graph with parent-child hierarchy. All spatial objects inherit from Node.

Methods
-
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.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
