Class Smooth

Some helpful interpolation functionality.

Inheritance

System.Object

Smooth

Namespace: GDX.Mathematics

Syntax

public static class Smooth

Methods

Exponential(Single, Single, Single, Single)

Smooths between previousValue and targetValue based on time since the last sample and a given half-life.

Declaration

public static float Exponential(float previousValue, float targetValue, float halfLife, float elapsedTime = NaNF)

Parameters

Type	Name	Description
System.Single	previousValue	Ideally, the previous output value.
System.Single	targetValue	The target value.
System.Single	halfLife	Half of the time it would take to go from previousValue to targetValue if time were constant.
System.Single	elapsedTime	The amount of time that has transpired since the previousValue was generated.

Returns

Type	Description
System.Single	A smoothed value.

Remarks

Assumes wibbly wobbly, timey wimey.

HalfLifeToSmoothingFactor(Single, Single)

Takes a halfLife value, and outputs a factor based on elapsedTime.

Declaration

public static float HalfLifeToSmoothingFactor(float halfLife, float elapsedTime = NaNF)

Parameters

Type	Name	Description
System.Single	halfLife	The desired halflife.
System.Single	elapsedTime	The time since the last sample.

Returns

Type	Description
System.Single	The coefficient value applied to the weight(t) of a lerp.

Remarks

Not providing a value for elapsedTime will result in using Time.deltaTime.
