MotionRanges class final

Constructors

MotionRanges({IntRange? depthCdp, List<int> releaseStiffnessPermille = const [900, 1000, 1100], int bounceJitterPermille = 0, int maxSettleMs = 360, int maxOvershootPermille = 100})

const

Properties

bounceJitterPermille → int

± bounce (ζ) jitter × 1000; bouncy families only.

final

depthCdp → IntRange?

Depth range in dp × 100, sampled on whole-dp steps (null = fixed).

final

hashCode → int

The hash code for this object.

no setter, inherited

maxOvershootPermille → int

Release overshoot ceiling × 1000.

final

maxSettleMs → int

Release settle ceiling.

final

releaseStiffnessPermille → List<int>

Release stiffness multipliers × 1000, picked uniformly.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

vary(MotionSpec base, Rng rng) → MotionSpec

Applies seeded variation to base from rng (the motion stream), clamped so overshoot ≤ 10 % and settle (≈ 4/(ζ√k)) ≤ maxSettleMs. Integer arithmetic only.

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Constants

minZetaFor10PercentOvershoot → const int

Smallest ζ × 1000 whose overshoot exp(−ζπ/√(1−ζ²)) is ≤ 10 %.
