Good evening All,

 

Just a quick question I have forked a gsap codepen that shows a method of playing timelines and navigating back and forth between them.

 

 

I can't take any credit for this pen, but what i was keen to do was ensure that no further calls to the timeline could be made whilst the tween is active (using the next and prev buttons). I have managed to do this by incorporating a ticker function and checking the tween through its life cycle and it works. I just wonder if there is a better way of doing this. Any advice or other suggestions most welcome i am eager to learn.

Hi iProov  :)

 

Welcome to the GreenSock forums.

 

I'm not sure I completely understand your question. Are you asking about the best way to check if a tween is running and prevent any events while it's active? The isActive() method (which you have in your function) is made for that. You don't have to check if the tween is active on every tick. You can simply check if it's active when your click event happens. If it is active, you can then prevent anything else from happening. GreenSock has a nice demo here:

More info about the isActive() method:

Hopefully that helps a little bit.

 

Happy tweening and welcome aboard.

Hi PointC

 

Thank you for the links, yes sorry for not being clear on what i was trying to achieve, what I meant was that I want to disable the "prev" button whilst the tween is active, which would stop the user double clicking the button, even though the button is already detecting if the tween is active it was still clickable and I was thinking in terms of user experience that ideally I would not what to give the user a false sense that an additional action was taking place.

 

My button has a simple click event attached that will only allow them to go onto the next label as long as the tween is not active

document.getElementById("prev").onclick = function(){
  
  if (!master.isActive()) {

    master.play("scene" + last);
    console.log("scene" + last);
       
    
  }
 
};

Now this works fine, My ideal case would be to disable this button whilst the tween is active, which makes clear to the user that no further clicking can take place.

 

I hope this makes better sense.

 

Many tnxs for such a warm Welcome :)
