Properties

absolutePosition

readonly absolutePosition: SimpleVector2Signal<Ray>

Defined in: 2d/src/lib/components/Node.ts:196 

A helper signal for operating on the position in world space.

Remarks

Retrieving the position using this signal returns the position in world space. Similarly, setting the position using this signal transforms the new value to local space.

If the new value is a function, the position of this node will be continuously updated to always match the position returned by the function. This can be useful to “pin” the node in a specific place or to make it follow another node’s position.

Unlike position, this signal is not compound - it doesn’t contain separate signals for the x and y components.

Inherited from

Curve.absolutePosition

absoluteRotation

readonly absoluteRotation: SimpleSignal<number, Ray>

Defined in: 2d/src/lib/components/Node.ts:231 

A helper signal for operating on the rotation in world space.

Remarks

Retrieving the rotation using this signal returns the rotation in world space. Similarly, setting the rotation using this signal transforms the new value to local space.

If the new value is a function, the rotation of this node will be continuously updated to always match the rotation returned by the function.

Inherited from

Curve.absoluteRotation

absoluteScale

readonly absoluteScale: SimpleVector2Signal<Ray>

Defined in: 2d/src/lib/components/Node.ts:331 

A helper signal for operating on the scale in world space.

Remarks

Retrieving the scale using this signal returns the scale in world space. Similarly, setting the scale using this signal transforms the new value to local space.

If the new value is a function, the scale of this node will be continuously updated to always match the position returned by the function.

Unlike scale, this signal is not compound - it doesn’t contain separate signals for the x and y components.

Inherited from

Curve.shrink

size

readonly size: Vector2LengthSignal<Ray>

Defined in: 2d/src/lib/components/Layout.ts:365 

Represents the size of this node.

Remarks

A size is a two-dimensional vector, where x represents the width, and y represents the height.

The value of both x and y is of type partials.Length which is either:

  • number - the desired length in pixels
  • ${number}% - a string with the desired length in percents, for example '50%'
  • null - an automatic length

When retrieving the size, all units are converted to pixels, using the current state of the layout. For example, retrieving the width set to '50%', while the parent has a width of 200px will result in the number 100 being returned.

When the node is not part of the layout, setting its size using percents refers to the size of the entire scene.

Example

Initializing the size:

// with a possible vector:
<Node size={['50%', 200]} />
// with individual components:
<Node width={'50%'} height={200} />

Accessing the size:

// retrieving the vector:
const size = node.size();
// retrieving an individual component:
const width = node.size.x();

Setting the size:

// with a possible vector:
node.size(['50%', 200]);
node.size(() => ['50%', 200]);
// with individual components:
node.size.x('50%');
node.size.x(() => '50%');

skew

readonly skew: Vector2Signal<Ray>

Defined in: 2d/src/lib/components/Node.ts:312 

Represents the skew of this node in local space of its parent.

Example

Initializing the skew:

// with a possible vector:
<Node skew={[40, 20]} />
// with individual components:
<Node skewX={40} skewY={20} />

Accessing the skew:

// retrieving the vector:
const skew = node.skew();
// retrieving an individual component:
const skewX = node.skew.x();

Setting the skew:

// with a possible vector:
node.skew([40, 20]);
node.skew(() => [40, 20]);
// with individual components:
node.skew.x(40);
node.skew.x(() => 40);

number

y

number

Returns

void

Inherited from

Curve.renderFromSource

reparent()

reparent(newParent): void

Defined in: 2d/src/lib/components/Node.ts:971 

Change the parent of this node while keeping the absolute transform.

Parameters

newParent

Node

The new parent of this node.

Returns

void

Remarks

After performing this operation, the node will stay in the same place visually, but its parent will be changed.

Inherited from

Curve.reparent

requestFontUpdate()

protected requestFontUpdate(): void

Defined in: 2d/src/lib/components/Layout.ts:819 

Apply any new font changes to this node and all of its ancestors.

Returns

void

Inherited from

Curve.requestFontUpdate

requestLayoutUpdate()

protected requestLayoutUpdate(): void

Defined in: 2d/src/lib/components/Layout.ts:759

Returns

void

Inherited from

Curve.requestLayoutUpdate

requiresCache()

protected requiresCache(): boolean

Defined in: 2d/src/lib/components/Node.ts:1338 

Whether this node should be cached or not.

Returns

boolean

Inherited from

Curve.requiresCache

requiresProfile()

protected requiresProfile(): boolean

Defined in: 2d/src/lib/components/Curve.ts:401 

Check if the path requires a profile.

Returns

boolean

Remarks

The profile is only required if certain features are used. Otherwise, the profile generation can be skipped, and the curve can be drawn directly using the 2D context.

Inherited from

restore()

Call Signature

restore(): void

Defined in: 2d/src/lib/components/Node.ts:1877 

Restore the node to its last saved state.

Returns

void

Remarks

This method can be used together with the save method to restore a node to a previously saved state. Restoring a node to a previous state removes that state from the state stack.

Example
const node = <Circle width={100} height={100} fill={"lightseagreen"} />
 
view.add(node);
 
// Save the node's current state
node.save();
 
// Modify some of the node's properties
yield* node.scale(2, 1);
yield* node.fill('hotpink', 1);
 
// Restore the node to its saved state
node.restore();
Inherited from

Curve.restore

Call Signature

restore(duration, timing?): ThreadGenerator

Defined in: 2d/src/lib/components/Node.ts:1906 

Tween the node to its last saved state.

Parameters
duration

number

The duration of the transition.

timing?

TimingFunction

The timing function to use for the transition.

Returns

ThreadGenerator

Remarks

This method can be used together with the save method to restore a node to a previously saved state. Restoring a node to a previous state removes that state from the state stack.

Example
const node = <Circle width={100} height={100} fill={"lightseagreen"} />
 
view.add(node);
 
// Save the node's current state
node.save();
 
// Modify some of the node's properties
yield* node.scale(2, 1);
yield* node.fill('hotpink', 1);
 
// Tween the node to its saved state over 1 second
yield* node.restore(1);

value

setupDrawFromCache()

protected setupDrawFromCache(context): void

Defined in: 2d/src/lib/components/Node.ts:1496

Parameters

context

CanvasRenderingContext2D

The context using which the cache will be drawn.

Returns

void

Remarks

This method is called before the contents of the cache canvas are drawn on the screen. It can be used to apply effects to the entire node together with its children, instead of applying them individually. Effects such as transparency, shadows, and filters use this technique.

Whether the node is cached is decided by the requiresCache method.

Inherited from
