Disable a tween and its scrollTrigger upon creation

[Thibka 3 Likes (Newbie)]

Hi, 

 

I'm trying to declare a simple tween with a scrollTrigger attached to it (like the one below for instance), but I want to control the moment this tween and its scrolltrigger are fired.

let tween = gsap.from('.text', {
    opacity: 0,
    duration: 2,
    scrollTrigger: {
        trigger: '.text',
    }
});

In other words, I just want to declare it, I don't want to play it right away!

Then, I want to be able to manually activate the scrollTrigger later on, and play the tween accordingly (if the element is in the viewport, the tween should play, else it should wait).

 

I've tried different combination of tween.scrollTrigger.disable(), tween.pause(), and also tried using the ScrollTrigger.create() approach but nothing seems to work!

 

Is that even possible? 🤔

 

Many thanks! 🙏

tween.pause().scrollTrigger.disable(); 

seems to work fine for me.

 

Happy tweening.

Just curious - why are you trying to declare it before you ever need it? Why not just create it when it's needed and not have to mess with disabling/pausing it?

Thanks @PointC it does work!
And now I'm wondering how I didn't manage to get it working on my own! 🥲

 

@GreenSock In this case I need my target element to be hidden for a while. And since I'm using a gsap.from tween to go from hidden to visible, I need to declare the tween asap.
The alternative would be to manually hide the element first (using gsap.set, vanilla js, or css), and then use a gsap.to when I'm ready, but I find this 2-step approach less clear/elegant. 🙂
