ColorGradient class Particles

A color curve over normalized time [0, 1], baked into a lookup table.

Like ParticleCurve but for linear RGBA colors. Used for color-over-life gradients. Linearly interpolates between stops and clamps to the first/last color outside their range.

Constructors

ColorGradient(List<ColorStop> stops, {int resolution = 64})
Builds a gradient from stops, baked into a resolution-entry table.
ColorGradient.constant(Vector4 color)
A gradient that is color everywhere.

Properties

hashCode → int
The hash code for this object.
no setterinherited
resolution → int
The number of baked lookup-table entries (each four floats).
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stops → List<ColorStop>
The source color stops, sorted by time, retained so the gradient can be serialized and edited (the sample path uses the baked table).
final

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
sample(double t, [Vector4? out]) → Vector4
Samples the gradient at normalized time t (clamped into [0, 1]), writing the result into out (allocated when null) and returning it.
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
