Methods

addChild

▸ addChild(child): boolean

Adds the given child to this node.

If the given child is already contained in this node or it already has a Node.parent then this method will fail (false will be returned).

Otherwise the child will be added to this node and the Node.EVT_CHILD_ADDED signal will be emitted.

Parameters

Name	Type	Description
`child`	`Node`	The child to be added to this node.

Returns

boolean

True on success otherwise false.

Inherited from

GraphicsNode.addChild

addChildren

▸ addChildren(children): void

Parameters

Name	Type
`children`	`Node`[]

Returns

void

Inherited from

GraphicsNode.addChildren

addScript

▸ addScript(assetId, params?): undefined | IScript

Adds a new script to this node.

Convenience wrapper around the scripts property, which validates the entry and rejects it if malformed. An entry whose asset is not available yet stays inert until it is.

Parameters

Name	Type	Description
`assetId`	`string`	The id of the script's TextAsset.
`params`	`ScriptParams`	Initial values for the script's editable properties.

Returns

undefined | IScript

A copy of the added script entry, or undefined if it was rejected. Use its id with getNodeScript() or removeScript().

Inherited from

canAddChild

▸ canAddChild(child): boolean

Returns true if the given child can be added to this node

Parameters

Name	Type
`child`	`Node`

Returns

boolean

Inherited from

GraphicsNode.canAddChild

canRemoveChild

▸ canRemoveChild(child): boolean

Parameters

Name	Type
`child`	`Node`

Returns

boolean

Inherited from

containsChild

▸ containsChild(child): boolean

Returns true if this node contains the given child

Parameters

Name	Type
`child`	`Node`

Returns

boolean

Inherited from

GraphicsNode.containsChild

copyFillTextureFrom

▸ copyFillTextureFrom(source): void

Copies the source's already-resolved texture directly, instead of just the fillTexture id (which would force a fresh async reload and flash the default white fill in the meantime).

Note: this node may not be attached to a scene yet, so don't call updateFillTexture() here to "double check" - it can't find its asset without a scene and would reset us back to white. onEnterScene() re-resolves the texture once the node actually gets attached.

Parameters

Name	Type
`source`	`GraphicsNode`

Returns

void

Inherited from

Inherited from

GraphicsNode.getAssetIds

getBoundingRect

Array of nodes this node depends on.

Inherited from

GraphicsNode.getDependencies

getDependencyIds

▸ getDependencyIds(): string[]

Returns the IDs of all nodes this node depends on. Subclasses that have dependencies (e.g. JointNode) should re-implement this method and return the IDs of the nodes that they depend on. The default implementation returns an empty array.

GraphicsNode.getDependencyIds

getDependents

Returns

Node[]

Array of Nodes that have this node as a dependency

Inherited from

getDescendants

▸ getDescendants(reversed?): Node[]

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

GraphicsNode.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.

Returns

Map<string, Node>

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

Inherited from

GraphicsNode.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

GraphicsNode.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

GraphicsNode.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.

▸ reorderChild(child, newIndex): boolean

Moves a child node to a different position (order) among the other children If the operation is successul then the EVT_CHILD_REORDERED signal will be emitted

Parameters

Name	Type	Description
`child`	`Node`	The child node to be moved
`newIndex`	`number`	The new index where the child node will be moved

Returns

boolean

true on success otherwise false

Inherited from

GraphicsNode.reorderChild

setExtras

▸ setExtras(_x): boolean

Sets any extra data that this object needs during de-serialization.

Returns true on success, otherwise returns false.

The default implementation does nothing and returns true.

Parameters

Name	Type
`_x`	`any`

Returns

boolean

Inherited from

GraphicsNode.setExtras

setFlag

▸ setFlag(flag, on?): void

Parameters

Name	Type	Default value
`flag`	`CoreObjectFlags`	`undefined`
`on`	`boolean`	`true`

Returns

void

Inherited from

GraphicsNode.setFlag

setPosition

▸ setPosition(v): void

Convenience method for setting the node's position to the given x,y

Parameters

Name	Type
`v`	`IPoint`

Returns

void

Inherited from

GraphicsNode.setPosition

setScenePosition

▸ setScenePosition(v): void

Sets the Node's scene position.

Parameters

Name	Type
`v`	`IPoint`

Returns

void

Inherited from

GraphicsNode.setScenePosition

setState

▸ setState(state, updateId?): boolean

Sets the object's state

Parameters

Name	Type	Default value	Description
`state`	`any`	`undefined`	The state to be set
`updateId`	`boolean`	`true`	Whether to also update the id property

Returns

boolean

True on success otherwise false

Inherited from

GraphicsNode.setState

testFlag

▸ testFlag(flag): boolean

Parameters

Name	Type
`flag`	`CoreObjectFlags`

Returns

boolean

Inherited from

GraphicsNode.testFlag

toGlobal

▸ toGlobal(position): Point

Parameters

Name	Type
`position`	`IPoint`

Returns

Point

Inherited from

GraphicsNode.toGlobal

toLocal

▸ toLocal(position): Point

Parameters

Name	Type
`position`	`IPoint`

Returns

Point

Inherited from

GraphicsNode.toLocal

toScreen

▸ toScreen(position, skipUpdate?): IPointData

Parameters

Name	Type
`position`	`IPoint`
`skipUpdate?`	`boolean`

Returns

IPointData

Inherited from

GraphicsNode.toScreen

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
