Constructors​

constructor​

public override new QuadBezierprops: QuadBezierProps: QuadBezier

Parameters

Overwrites Bezier.constructor

Properties​

absolutePosition​

readonly public absolutePosition: SimpleVector2SignalQuadBezier

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 Bezier.absolutePosition

absoluteRotation​

readonly public absoluteRotation: SimpleSignalnumberQuadBezier

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 Bezier.absoluteRotation

absoluteScale​

readonly public absoluteScale: SimpleVector2SignalQuadBezier

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.

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:

size​

readonly public size: Vector2LengthSignalQuadBezier

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.

restore​

public restore(): void
public restoreduration: numbertiming?: TimingFunction: ThreadGenerator

Restore the node to its last saved state.

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.

Inherited from Bezier.save

snapshotClone​
