frc.spectrumLib.util.ExpCurve

public class ExpCurve
extends Curve

This class maps the value of a input to an exponential curve. It is a subclass of Curve. Modified to allow outputs larger than 1.0

Constructor Summary

Constructor Details

ExpCurve

public ExpCurve()

Constructs an Exponential Curve object which can be used to map a stick input exponentially. Initialized with default values: expVal = 1.0; offset = 0.0; scalar = 1.0; deadzone = 0.0;

ExpCurve

public ExpCurve(double expVal,
 double offset,
 double scalar,
 double deadzone)

Constructs an Exponential Curve object which can be used to map a stick input exponentially. Initialized with values provided.

Parameters:

expVal - value of the base of the exponent used in the curve

offset - value used to offset the final curve

scalar - value used to scale the value before offset

deadzone - value for the width of the deadband in the center of the curve

Method Details

calculate

public double calculate(double input)

Applies the full exponential curve pipeline: deadzone, exponent, scalar, then offset.

Specified by:

calculate in class Curve

Parameters:

input - the raw input value to be mapped (typically in [-1, 1])

Returns:

the mapped output value

setExpVal

public void setExpVal(double expVal)

Sets the value of expVal, the base of the exponent used to map the input.

Parameters:

expVal - the new value of expVal

getExpVal

public double getExpVal()

Returns the value of expVal, the base of the exponent used to map the input.

Returns:

the current value of expVal
