All Implemented Interfaces:

LXComponent.Renamable, LXLoopTask, LXPath, LXSerializable, LXParameter, LXParameterListener

public class Accumulator
extends LXModulator

An accumulator oscillates between increasing and decreasing value by some velocity such that it never overflows or stops moving outside of the floating point range. If it hits the extremes of the floating point range then it reverses direction and keeps going. This is useful in extremely long-running programs that wish to seed a value for something like a noise function, without discontinuity.

Method Detail

computeValue

protected double computeValue(double deltaMs)

Description copied from class: LXModulator

Implementation method to advance the modulator's internal state. Subclasses must provide and update value appropriately.

Specified by:

computeValue in class LXModulator

Parameters:

deltaMs - Number of milliseconds to advance by

Returns:

Computed value
