Animation runs repeatedly in interactive mode with loop={false} #71

Describe the bug
When set to not loop and play the animation once in a block, the expectation I have is that upon entering the block the animation will play once and then not repeat. Instead, the result is that the animation plays once and then replays again on each incremental interaction.

To Reproduce
Steps to reproduce the behavior:

  1. Set up an animation with the props:
        loop={false}
        interactivity={{
          mode: "scroll",
          actions: [
            { visibility: [0, 0.3], type: "stop", frames: [0] },
            { visibility: [0.3, 1.0], type: "play", frames: [0, 38] }
          ]
        }}
  1. Scroll until 30% visible and observe one playthrough
  2. Scroll until 31% visible and observe a second playthrough

Expected behavior
The expectation would be that the playthrough would happen once while the user was in section 30%-100% and then not play again.

Relatedly, if one tries to circumvent this by taking a small section as your "play" section and then setting it as a "stop" section after the user leaves the section, it still doesn't work. If the user scrolls through the slice too quickly, it just jumps to the last frame:

        interactivity={{
          mode: "scroll",
          actions: [
            { visibility: [0, 0.3], type: "stop", frames: [0] },
            { visibility: [0.3, 0.31], type: "play", frames: [0, 38] },
            { visibility: [0.31, 1.0], type: "stop", frames: [38] }
          ]
        }}

Hey @zackdotcomputer

Did you find a solution for this at the end ?
I'm facing the same problem right now

I'm dealing with something similar right now.

const interactivity = {
  mode: "scroll",
  actions: [
    {
      visibility: [0, 1],
      type: "play",
    }
  ],
};

const LottieTest = () => {
  return (
    <Lottie
      animationData={animationData}
      style={style}
      interactivity={interactivity}
      loop={false}
    />
  );
};

The animation plays when in viewport, but every time I scroll a lil' bit while in view it starts playing all over again.
Over at Lottie-interactivity docs, you can pass "playOnce" to "type":

https://docs.lottiefiles.com/lottie-interactivity/animation-modes#animate-when-visible-and-play-once

This doesn't work with lottie-react unfortunately.
@Gamote Can this be addressed?

Yes, I have same problem. You might add some loop of the animation end, and the problem will be solved

`const handler = useCallback((evt: any) => {
    if (Math.floor(evt.currentTime) === 180) {
        lottie.current && lottie.current.goToAndPlay(110, true);
    }
}, []);

return (
    <Lottie
        lottieRef={lottie}
        className={props.className}
        animationData={json}
        onEnterFrame={handler}
        interactivity={{
            mode: 'scroll',
            actions: [
                {
                    visibility: [0, 1],
                    type: 'play',
                    frames: [0],
                },
            ],
        }}
    />
);`
