public class Accelerator
extends LXModulator

An accelerator is a free-running modulator that changes its value based on velocity and acceleration, measured in units/second and units/second^2, respectively.

Method Details

onReset

protected void onReset()

Description copied from class: LXRunnableComponent

Optional subclass method when reset happens.

Overrides:

onReset in class LXRunnableComponent

getVelocity

public double getVelocity()

Returns:

the current velocity

getVelocityf

public float getVelocityf()

Returns:

the current velocity as a floating point

getAcceleration

public double getAcceleration()

Returns:

The current acceleration

getAccelerationf

public float getAccelerationf()

Returns:

The current acceleration, as a float

setSpeed

public Accelerator setSpeed(double initVelocity,
 double acceleration)

setSpeed

public Accelerator setSpeed(LXParameter initVelocity,
 LXParameter acceleration)

Sets both the velocity and acceleration of the modulator. Updates the default values so that a future call to trigger() will reset to this velocity.

Parameters:

initVelocity - New velocity

acceleration - Acceleration

Returns:

this

setVelocity

public Accelerator setVelocity(double velocity)

Updates the current velocity. Does not reset the default.

Parameters:

velocity - New velocity

Returns:

this

setInitVelocity

public Accelerator setInitVelocity(double initVelocity)

Sets the initial velocity to a fixed value

Parameters:

initVelocity - Fixed initial velocity value

Returns:

this

setInitVelocity

public Accelerator setInitVelocity(LXParameter initVelocity)

Sets initial velocity of the Accelerator

Parameters:

initVelocity - Initial velocity parameter

Returns:

this

setAcceleration

public Accelerator setAcceleration(double acceleration)

setAcceleration

public Accelerator setAcceleration(LXParameter acceleration)

Updates the acceleration.

Parameters:

acceleration - New acceleration

Returns:

this

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
