我怎样才能让这个翻滚动画的一部分连续循环?

How can I get one section of this rollover animation to loop continuously?

我有一个动画,我想将其用于具有以下基本状态的翻转效果:

  1. 静止:在第 0 帧和第 55 帧之间连续循环
  2. 鼠标输入:播放一次 第 56 到 78 帧,然后在第 78 帧暂停
  3. 鼠标移开:播放一次 帧 79-95,然后 return 休息

除了静止状态下的连续循环外,我几乎都能正常工作。循环只播放一次,然后静止不动。我的代码如下:

代码笔:https://codepen.io/anon/pen/pBXKeN

var animationContainer = document.getElementById("animation-container");

var animation = lottie.loadAnimation({
    wrapper: document.getElementById("animation-wrapper"),
    renderer: "svg",
    loop: false,
    autoplay: false,
    prerender: true,
    animationData: animationData,
});

animation.addEventListener('DOMLoaded',resting);
animationContainer.addEventListener("mouseenter", hoverStart);
animationContainer.addEventListener("mouseleave", hoverEnd);

function resting() {
    animation.removeEventListener("complete", resting);
    console.log('resting');
    animation.playSegments([0, 55], true);
}

function hoverStart() {
    console.log('hover started');
    animationContainer.removeEventListener("mouseenter", hoverStart);
    animation.playSegments([56, 78], true);
    animationContainer.addEventListener("mouseleave", hoverEnd);
}

function hoverEnd() {
    console.log('hover ended');
    animationContainer.removeEventListener("mouseleave", hoverEnd);
    animation.playSegments([79, 95], true);
    animation.addEventListener("complete", resting);
    animationContainer.addEventListener("mouseenter", hoverStart);
}

我尝试将循环设置为 true,但这会导致所有 3 个状态循环,这不是 mouseenter 和 mouseleave 效果的预期效果。有没有办法让单个部分循环播放?

另外,我很乐意切换到 jQuery 如果它能让事情变得更简单。

通过将循环设置为 true、在 2 帧之间循环以获得 "pause" 效果以及更密切地监视悬停状态的组合来解决。我确信这可以进一步改进,但在这一点上我很高兴它能正常工作。

var hover = false;

animationContainer.addEventListener("mouseenter", hoverStart);
animation.addEventListener('DOMLoaded',resting);

function resting() {
  console.log('resting. hover status: ' + hover);
  animation.removeEventListener("loopComplete", resting);
  animation.playSegments([0, 55], true);
}

function hoverStart() {
  console.log('hover started. hover status: ' + hover);
  animationContainer.removeEventListener("mouseenter", hoverStart);
  animation.playSegments([56, 78], true);
  animation.addEventListener("loopComplete", hoverPause);
}

function hoverPause() {
  console.log('hover paused. hover status: ' + hover);
  animation.removeEventListener("loopComplete", hoverPause);
  animationContainer.addEventListener("mouseleave", hoverEnd);
  animation.playSegments([77, 78], true);
  console.log('hover pause complete. hover status: ' + hover);
  if (!hover) {
    animation.addEventListener("loopComplete", hoverEnd);
  }
}

function hoverEnd() {
  console.log('hover ended. hover status: ' + hover);
  animationContainer.removeEventListener("mouseleave", hoverEnd);
  animation.removeEventListener("loopComplete", hoverEnd);
  animation.playSegments([79, 95], true);
  animation.addEventListener("loopComplete", resting);
  animationContainer.addEventListener("mouseenter", hoverStart);
}

animationContainer.onmouseout = function () {
    hover = false;
}
animationContainer.onmouseover = function () {
    hover = true;
}
