How to get instant spin knob angle value made with draggable

Recommended Posts

I made spinning knob button with draggable. I used snap option. I want to get instantly my button's angle value. How can I get that?

 

var rotationSnap = 60;
   Draggable.create("#knob", {
      type:"rotation",
      throwProps:true,
      snap:function(endValue) { 
          return Math.round(endValue / rotationSnap) * rotationSnap;
      }
    });

Hi and welcome to the GreenSock forums.

 

There are a few ways to get the rotation:

 

//from onDrag callback
this.rotation

//from element
document.getElementById("knob")._gsTransform.rotation

//from Draggable:
Draggable.get("#knob").rotation


 

 

run this demo with console open to see 3 ways of getting the rotation
