I was wondering if there should be a config available for Bounce ease as well like the ones that are available in Elastic as well as Back eases.

 

The use-case for example is to control the number of bounces as well as the amplitudefor lack of a better word i.e. the force with which it bounces back everytime it hits the floor.

 

Example: jsFiddle.

 

Thoughts?

Very simple decay...

See the Pen RNZmEO by osublake (@osublake) on CodePen

 

A better way to calculate it...

var amplitude = 90; 
var decay = 0.5; 
var freq = 1; 

y -= amplitude * Math.cos(freq * time * 2 * Math.PI) / Math.exp(decay * time);

The configurable Bounce is a great suggestion. We have a long feature-list for easing enhancements and just need to find the time.

Yeah, it's a good suggestion Tahir. We've had some longer-term plans that will address this (and a lot more), but it's not a small undertaking. If you're patient, I think you'll be really pleased with what we eventually come up with :)

Three years later, wondering whether there's been any progress on this front?
