FCurve

@Serializable

data class FCurve(val segments: List<Segment2D>)(source)

Represents a functional curve composed of multiple 2D segments. It provides utilities to manipulate and query the curve, such as reversing its direction, changing its speed, sampling values, and visualizing it as contours.

Parameters

segments

a list of 2D segments that define the curve

Constructors

FCurve

constructor(segments: List<Segment2D>)

Properties

bounds

val bounds: Rectangle

duration

val duration: Double

The duration of the FCurve, calculated as the difference between its start and end points. Returns 0.0 if the FCurve has no segments.

end

val end: Double

Represents the x-coordinate of the endpoint of the last segment in the FCurve.

max

val max: Double

Represents the maximum y-coordinate value of the FCurve at its bounds.

min

val min: Double

Represents the minimum value of the curve.

segments

val segments: List<Segment2D>

start

val start: Double

Represents the starting x-coordinate of the first segment in the FCurve. If the segments list is empty, it defaults to 0.0.

Functions

changeSpeed

fun changeSpeed(speed: Double): FCurve

Change the duration of the Fcurve

contours

fun contours(scale: Vector2 = Vector2(1.0, -1.0), offset: Vector2 = Vector2.ZERO): List<ShapeContour>

Return a list of contours that can be used to visualize the Fcurve

reverse

fun reverse(): FCurve

Reverse the fcurve

sampler

fun sampler(normalized: Boolean = false): (Double) -> Double

Creates a function to sample the FCurve at a specific time.

value

fun value(t: Double, segment: Segment2D? = null): Double

Evaluate the Fcurve at t

valueWithSegment

fun valueWithSegment(t: Double, cachedSegment: Segment2D? = null): Pair<Double, Segment2D?>

Evaluate the Fcurve at t
