inertiaplugin InertiaPlugin.track returns Array?

[joris-rotteveel]

Hi,

 

I just bought a subscription to GSAP in order to use the InertiaPlugin. Unfortunately I am running into issues with the track function

 

var tracker = InertiaPlugin.track(slider, 'x');
const vel = tracker.getVelocity('x');

The function track seems to be returning an Array and not a VelocityTracker object? I've created a codepen that demonstrates what I mean.

Can someone point out what the correct  way is to grab the velocity using the InertiaPlugin please?

It now returns an array of trackers. Check out the first item in the array.

The format will be like this.

 

var vx = tracker.get("x");

Thank you @OSUblake ,

 

 

That does the trick, the docs might not be up to date then : https://greensock.com/docs/v3/Plugins/InertiaPlugin/static.track()

Thanks for pointing that out, @joris-rotteveel. I just updated that function in the docs. Sorry about any confusion there. 

 

The reason it returns an Array is because you could pass selector text as the "target" that results in multiple targets, like:

var trackers = InertiaPlugin.track(".class", "x,y"); // returns an array with one VelocityTracker per .class element.

console.log(trackers.length); // however many ".class" elements there are. 

Happy tweening!
