Hi  I'm wondering if there's a way to set a max velocity? I'm using a proxy div and having my elements respond the proxy.x positions the problem is with a slight flick sends my elements flying off screen because of the start velocity is a large number so I think restraining the max velocity will solve this.


Here's my setup

let proxy = $("<div>");
Draggable.create(proxy, {
  trigger: box,
  	//code for elements.x = this.x
  snap:function(endValue) { 
                return Math.round(endValue / 80) * 80;

No there is no setting to set maximum velocity. You can instead set  max and min duration and resistance. Check throwProps under 'Config object properties' https://greensock.com/docs/Utilities/Draggable


What you are doing might be done without Draggable, you can use ThrowPropsPlugin directly to track velocity. And use Physics2DPlugin.

Yep, @Sahil is exactly right - you probably only need ThrowPropsPlugin because it can track the velocity of any property of any object, and you can just do a regular throwProps tween whenever you want. You'd define an "end" value inside the throwProps object to do your custom snapping logic. 

ThrowPropsPlugin.track(object, "x"); //I'm not quite sure what you're tracking

TweenMax.to(yourOtherObject, 1, {
      velocity:ThrowPropsPlugin.getVelocity(object, "x"),
      end: function(endValue) { 
            return Math.round(endValue / 80) * 80;


That assumes you want a particular duration (1 second in this case), but you can use ThrowPropsPlugin.to() if you want that duration to be automatically calculated based on the velocity. 


I doubt you even need Physics2DPlugin.

I need to track velocity because I want to do a certain animation when velocity hits certain ranges, I just didn't include the code in my sample. I believe this might work as long the initial velocity is not a large number. I'll give it try. Thanks for the responses!
