Constructors​

constructor​

public override new View2Dprops: View2DProps: View2D

Parameters

Overwrites Rect.constructor

Properties​

absolutePosition​

readonly public absolutePosition: SimpleVector2SignalView2D

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

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 Rect.absolutePosition

absoluteRotation​

readonly public absoluteRotation: SimpleSignalnumberView2D

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

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 Rect.absoluteRotation

absoluteScale​

readonly public absoluteScale: SimpleVector2SignalView2D

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

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.

cachePadding​

readonly public cachePadding: SpacingSignalView2D

readonly public endOffset: SimpleSignalnumberView2D

The offset in pixels from the end of the curve.

This property lets you specify where along the defined curve the actual visible portion ends. For example, setting it to 20 will make the last 20 pixels of the curve invisible.

This property is useful for trimming the curve using a fixed distance. If you want to animate the curve appearing on the screen, use end instead.

Inherited from Rect.minWidth

offset​

readonly public offset: Vector2SignalView2DVector2SignalContextView2D

Represents the offset of this node's origin.

By default, the origin of a node is located at its center. The origin serves as the pivot point when rotating and scaling a node, but it doesn't affect the placement of its children.

The value is relative to the size of this node. A value of 1 means as far to the right/bottom as possible. Here are a few examples of offsets:

  • [-1, -1] - top left corner
  • [1, -1] - top right corner
  • [0, 1] - bottom edge
  • [-1, 1] - bottom left corner

The value represents the radius of the quarter circle that is used to round the corners. If the value is a number, the same radius is used for all corners. Passing an array of two to four numbers will set individual radii for each corner. Individual radii correspond to different corners depending on the number of values passed:

// top-left-and-bottom-right | top-right-and-bottom-left
[10, 30]
// top-left | top-right-and-bottom-left | bottom-right
[10, 20, 30]
// top-left | top-right | bottom-right | bottom-left
[10, 20, 30, 40]

Inherited from Rect.shadowOffset

shrink​

readonly public shrink: SimpleSignalnumberView2D
Inherited from Rect.shrink

size​

readonly public size: Vector2LengthSignalView2D

Represents the size of this node.

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 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.

Examples

Inherited from Rect.size

readonly public skew: Vector2SignalView2DVector2SignalContextView2D

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

Examples

Inherited from Rect.skew

smoothCorners​

readonly public smoothCorners: SimpleSignalbooleanView2D

This property only affects the way rounded corners are drawn. To control the corner radius use the radius property.

When enabled, rounded corners are drawn continuously using Bézier curves rather than quarter circles. The sharpness of the curve can be controlled with cornerSharpness.

You can read more about corner smoothing in this article by Nick Lawrence.

Examples

Inherited from Rect.smoothCorners

start​

readonly public start: SimpleSignalnumberView2D

Inherited from Rect.start

Use arrowSize to control the size of the arrow.

Inherited from Rect.startArrow

startOffset​

readonly public startOffset: SimpleSignalnumberView2D

The offset in pixels from the start of the curve.

This property lets you specify where along the defined curve the actual visible portion starts. For example, setting it to 20 will make the first 20 pixels of the curve invisible.

This property is useful for trimming the curve using a fixed distance. If you want to animate the curve appearing on the screen, use start instead.

public save(): void

Push a snapshot of the node's current state onto the node's state stack.

This method can be used together with the restore method to save a node's current state and later restore it. It is possible to store more than one state by calling save method multiple times.

Inherited from Rect.save

snapshotClone​

public snapshotClonecustomProps: NodeState = {}: View2D

Create a copy of this node.

Unlike clone, a snapshot clone calculates any reactive properties at the moment of cloning and passes the raw values to the copy.

Parameters

Inherited from Rect.snapshotClone

toPromise​

public toPromise(): PromiseView2D

Wait for any asynchronous resources that this node or its children have.

Certain resources like images are always loaded asynchronously. Awaiting this method makes sure that all such resources are done loading before continuing the animation.

view​

public override view(): View2D
Overwrites Rect.view

worldToLocal​

public worldToLocal(): DOMMatrix

Get the world-to-local matrix for this node.

This matrix transforms vectors from world space to local space of this node.

Examples

Inherited from Rect.worldToLocal

worldToParent​

public worldToParent(): DOMMatrix

Get the world-to-parent matrix for this node.

This matrix transforms vectors from world space to local space of this node's parent.
