Firing events whilst dragging (draggable)

[ochalmers]

I've read through the docs but couldn't find anything relating to this in there. Is it possible for us to trigger functions or other tweens whilst dragging in draggable? For example if you started dragging, the container would tween to an opacity change or the cursor would change whilst you were dragging then change back when you let go. 

 

I've attached a pen I have that uses draggable if it's any help to work with.

 

Thanks!

Sure. you can set up an onDrag callback to run whatever logic you want while dragging.

Here are 2 examples:

In addition to Carl's answer/really useful links , you can do something like one of these :

 

using onPress/Release :

var  tween= TweenLite.to('#container ',0.2,{opacity:0.5,paused:true});

var draggables = Draggable.create(".box", {
onPress:function(){tween.play()},
onRelease:function(){tween.reverse()}
});

or run a function on Drag :

var DTween=1 , tween=TweenLite.to('#container ',0.2,{opacity:0.5,paused:true});

var draggables = Draggable.create(".box", {
onDrag:function(){
  if(!DTween){return false}; // return false to avoid run on Drag repeatedly
  tween.play();
  DTween=0; 
},
onRelease:function(){
  tween.reverse();
  DTween=1;
}
});
