FlightParametrics

Introduction

FlightParametrics is an easy to use enum which can be used as a type, and can calculate the normalized progress, ranging from 0.0 to 1.0, for the most common parametric easings.

Basic Use

// Can be declared as an Equatable
// property, supports == / !=

var easing : FPEasing = .inOutCubic   

// Returns the parametric progress based
// on some calculated relative linear
// progress from 0.0 - 1.0

var progress = easing.parametricProgress(relativeProgress)  

// You can ask an easing for its inverse
// which will return it's corresponding
// inverse parametric function
//
//  i.e .inOutCubic -> .outInCubic
//      .inSine -> .outSine
//      .outCircular -> .inCircular

var revEasing = easing.reverseEasing()  

These are the supported parametric curves that you can apply to the property animation.
