My animation won't start in some cases

[ben-lau]

Hello, I have a ludo game project with pixi.js, and I use TweenLite to control my animation, and I use Promise.all to return an animate completion status, just like this: But in some cases, I found my promise is not fulfilled, so I try to log in onStart and onComplete, and neither the complete won't fire, nor the start. I cant locate the inevitable situation, case it's look like it appears randomly.

FYI, the version of my gsap is 3.7.0

TweenLite is deprecated. Check out the migration guide.

It's hard to debug based on a snippet of code. Are you're overwriting the animations, like maybe calling jumpTo too quickly, or animating the scale in another method?

That said, I would probably try this. There's no need to use Promise.all.

jumpTo({ x, y }) {
  const initialScale = this.scale;
  return gsap.timeline()
    .to(this, {
      x, y,
      duration: 0.3,
      ease: "none"
    })
    .to(this.scale, {
      duration: 0.1,
      yoyo: true,
      repeat: 1,
      ease: "none",
      x: initialScale.x * 1.2,
      y: initialScale.y * 1.2,
    }, 0.1);
}

I haven't overwriting any animations, and my project is a ludo game, jumpTo is the method of my chess view, i called jumpTo when the previous jumpTo is done:

I found this problem when I resized my window quickly, so I know it's hard to locate the problem, but I also issued this to see if I can remind you of anything.

By the way, I solved this problem with using your suggestion, thanks. Is there any different from timeline and tween?

Is there any different from timeline and tween?

A timeline is a container for tweens, so it's helpful if you want to group and sequence animations.

ok, here is another question, I found animation will paused when my window is in the background, therefore my move task will pause because of promise pending status. I use Promise.race to this animation and a promise of setTimeout to solve it, Is there anyother solution?

Do you mean like when you change tabs? Have you seen this helper function. https://greensock.com/docs/v3/HelperFunctions#hidden
