Class FeedbackPulseExpander

Pure expansion of a pulsing vibration — an authored frequency and duty cycle — into the concrete FeedbackPatternStep sequence a pattern player walks. Engine-free and directly unit-testable, mirroring FeedbackScaler's role as the single place a shaping rule lives.

Syntax

public static class FeedbackPulseExpander

Methods

Expand(FeedbackIntensity, float, float, float)

Expands a peak impulse pulsing at frequencyHertz with the given dutyCycle into an ordered step sequence covering totalDurationSeconds.

Declaration

public static IReadOnlyList<FeedbackPatternStep> Expand(FeedbackIntensity peak, float frequencyHertz, float dutyCycle, float totalDurationSeconds)

Parameters

Type	Name	Description
FeedbackIntensity	peak	Peak low/high motor amplitudes each pulse reaches (its own Duration is ignored — the on-time of each step is derived from dutyCycle instead).
float	frequencyHertz	Pulses per second. At or below zero, the whole duration collapses into a single continuous step (no pulsing).
float	dutyCycle	Fraction of each period the motor is on, clamped to (0, 1].
float	totalDurationSeconds	Total length of the expanded sequence, in seconds; clamped to non-negative.

Returns

Type	Description
IReadOnlyList<FeedbackPatternStep>	The ordered pulse steps: one step per period (StartOffsetSeconds = i / frequencyHertz, on-time = dutyCycle / frequencyHertz), step count = ceil(frequencyHertz * totalDurationSeconds), with the last step's on-time truncated so no step runs past totalDurationSeconds.
