Robert Penner's easing functions, slightly modified

Package Exports

  • tween-functions

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (tween-functions) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Tween-functions

Robert Penner's tweening functions as used in React-tween-state and React-state-stream.

Penner's original functions uses the change in value rather than final value as parameter. I much prefer the latter, so this is what this library will use.

API

tweenFunction.tweenName(currentTime, beginValue, endValue, totalDuration)

Example

var tweenFunctions = require('tween-functions');
tweenFunctions.easeInQuad(1, 0, 50, 5); // => 4
