Returns the descendants of this node.

A descendant is node that has this node as an ancestor. Consider for example the following tree of nodes:

• NodeA
  • NodeB
    • NodeD
    • NodeE
  • NodeC

If we ask for the descendants of NodeA we'll get back: [NodeB, NodeD, NodeE, NodeC]

If reversed is set to true then this method will return the reversed descendants. For the example above, that would be: [NodeC, NodeE, NodeD, NodeB, NodeA]. Note that the first item of the reversed descendants has the highest z-index.

Parameters

Name	Type	Default value
reversed	boolean	false

Returns

Node[]

A list of this node's descendants

Inherited from

Node.getDescendants

---

Returns a map of all descendants keyed by their IDs.

This provides efficient lookup of any descendant node by its ID without having to traverse the tree multiple times.

A Map where keys are node IDs and values are the corresponding Node objects

Inherited from

Node.getDescendantsMap

---

getExtras

▸ getExtras(): any

Returns any extra data that this object needs to save during serialization.

In some cases an object might need to save some extra data without necessarily this extra data being part of its state (e.g. the AssetsLibrary of a Scene). In these cases subclasses can re-implement this method and return the data required.

The default implementation returns undefined meaning that no extra data needs to be saved during serialization.

Returns

any

Inherited from

Node.getExtras

---

---

getSceneTransform

▸ getSceneTransform(): Matrix

Returns a copy of this node's scene transformation matrix. Use this matrix to map coordinates from this node's local coordinate system to the scene's coordinate system. To map coordinates from the scene, you must first invert the returned matrix.

Unlike getLocalTransform(), which returns only the local transformation, this function includes the node's (and any parents') position, and all the transfomation properties.

Returns

Matrix

Inherited from

Node.getSceneTransform

---

getShape

▸ getShape(): Polygon

Returns the shape of this Node in local coordinates.

Note that the returned shape might be empty.

The shape of a Node is used for many things, including boolean operations and selection.

Returns

Polygon

Inherited from

Node.getShape

{
	id: "Ssba4ch5ruok",
	name: "Circle",
	radius: 2,
   // ...
}

To avoid including properties that are currently in their default value you can set minified = true when calling getState.

update

▸ update(delta): void

Updates this node.

The default update will do the following:

• It will call the update method for all NodeScripts attached to this node
• Advance the visual filters that animate, see VisualFiltersMixin.update
• Call update for each child of this node.

Children are iterated over a shallow copy of _children, not the live array, since a NodeScript's update() may insert/remove siblings on this node (e.g. Breakable spawning fragments); iterating the live array would skip or double-visit siblings shifted by those mutations.

Parameters

Name	Type	Description
delta	number	The fixed simulation step, in milliseconds

Returns

void
