Class: GearNode

Represents a simple spur gear.

The gear geometry is specified by 3 parameters:

Radius is essentially the outer radius of the gear. The height of each gear tooth is defined by toothHeight. This means that the inner radius of the gear is radius - toothHeight. Finally the density of the gear teeth is specified by toothDensity.

Accessors

active

• get active(): boolean

Returns true if this body is active, otherwise returns false.

An inactive body will be visualized but it won't participate in the simulation.

Returns

boolean

Inherited from

MultipartBodyNode.active

• set active(v): void

Sets this body's active property

Parameters

Name	Type
`v`	`boolean`

Returns

void

Inherited from

allowSleep

• get allowSleep(): boolean

Returns true if this body is allowed to sleep, otherwise returns false.

By default, all bodies are allowed to sleep. This basically means that when a body has come to rest and it has no collisions then it will go to sleep. Setting a body to sleep reduces then number of object we have to simulated (thus increasing performance).

Returns

boolean

Inherited from

MultipartBodyNode.allowSleep

• set allowSleep(v): void

Sets this body's allowSleep property

Parameters

Name	Type
`v`	`boolean`

Returns

void

Inherited from

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.

Array of nodes this node depends on.

Inherited from

MultipartBodyNode.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.

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

Returns

Node[]

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.

An entry that has no NodeScript is left out, so the result can be shorter than scripts.

Returns

NodeScript[]

Inherited from

▸ getNodeScriptsByClassName(className): NodeScript[]

Returns all NodeScripts whose class name matches the given className.

Parameters

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

MultipartBodyNode.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.

The default implementation calls getBoundingRect() to return a simple rectangular shape, but subclasses can reimplement this function to return a more accurate shape for non-rectangular items.

Returns

Polygon

Inherited from

MultipartBodyNode.getShape

getSnapPoints

▸ getSnapPoints(snapMode): ISnapPoint[]

Snap Points

Parameters

Name	Type
`snapMode`	`number`

Returns

ISnapPoint[]

Inherited from

MultipartBodyNode.getSnapPoints

getState

▸ getState(minified?): any

Returns this object's state

The object's state is an object containing key/value pairs corresponding to this object's properties. For example:

{
	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.

Note that read-only properties are not part of the object's state (with the exception of the id)

Parameters

Name	Type	Default value	Description
`minified`	`boolean`	`false`	Whether to return a minified state or not

Returns

any

Inherited from

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
