Class: LightNode

A 2D light with shadows.

The light casts rayCount rays from its position, evenly spread over coneAngle, and clips each one at the first body it hits. The clipped rays form a fan that is drawn additively into the Scene's LightLayer, so bodies occlude the light and leave shadows behind them. Each ray fades out toward its end, and a softShadowLength above zero gives the fan a feathered edge past every obstacle.

A light that is a child of a BodyNode follows it and is not blocked by it.

The node's own container only holds the light bulb sprite. The light geometry lives in the Scene's lights layer, in scene coordinates, because the rays are cast in the physics world. Node.alpha works as the light's intensity.

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]

Map<string, Node>

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

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.

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