我想使用 TweenMax 和 J-Query 更改图片。但它比 setInterval 集要慢。

我没有任何其他设置，我只是用它们来改变图片。而在 twinmax 中，没有 setinterval 设置。

从左侧的 scale x : 0 开始并在我向右传递时缩小，以便我身后的背景图像在指定时间发生变化。

换图片的时间越来越慢。我无法上传图片，因为我不知道如何上传。

我想同时转换，有没有更好的方法？我可以只用css和关键帧来做吗？

$(function() {
  var roll = 1;
  setInterval(function() {
    roll++;
    if (roll > 2) {
      roll = 1;
    }
    $("#box1").attr("src", "assets/images/top/pc/main_" + roll + "_b.png");
  }, 4000);
})

$(function() {
  var roll = 1;
  setInterval(function() {
    roll++;
    if (roll > 2) {
      roll = 1;
    }
    $("#box2").attr("src", "assets/images/top/pc/main_" + roll + "_b.png");
  }, 5000);
})

var tl = new TimelineMax({
  repeat: -1,
  repeatDelay: 3
});
tl.from(".layer1", 0.8, {
  scaleX: 0,
  transformOrigin: "left",
  ease: 'expo.inOut'
});
tl.to(".layer1", 0.8, {
  scaleX: 0,
  transformOrigin: "right",
  ease: 'expo.out'
});

var ta = new TimelineMax({
  repeat: -1,
  repeatDelay: 4
});
ta.from(".layer2", 0.8, {
  scaleX: 0,
  transformOrigin: "left",
  ease: 'expo.inOut'
});
ta.to(".layer2", 0.8, {
  scaleX: 0,
  transformOrigin: "right",
  ease: 'expo.out'
});

当粉红色层穿过标题部分时，我想表达背面图像的变化。

我想在 5 个图像框中表达相同的内容。

我已经设法参数化和计算正确的动画和幻灯片间隔。

var rollImg = ["https://media.istockphoto.com/photos/fire-letter-a-of-burning-flame-picture-id844027508?k=6&m=844027508&s=170667a&w=0&h=dt0qXfyejRq_kjs5PqXcMf7Fij_opW7w1kfhfmH6dyQ=",

var layer1Interval = 4000;
var layer2Interval = 5000;
var animationInterval = 1000;
$(function() {
  var roll = 1;
  function rollFnc () {
    setTimeout(function() {
      roll++;
      if (roll > 2) {
        roll = 1;
      }
      $("#box1").attr("src", rollImg[roll - 1]);
      setTimeout(rollFnc, layer1Interval + animationInterval * 1.5);
    }, animationInterval / 2);
  }
  
  rollFnc();
})

var tl = new TimelineMax({
  repeat: -1,
  repeatDelay: (layer1Interval / 1000)
});
tl.from(".layer1", animationInterval / 1000, {
  scaleX: 0,
  transformOrigin: "left",
  ease: 'expo.inOut'
});
tl.to(".layer1", animationInterval / 1000, {
  scaleX: 0,
  transformOrigin: "right",
  ease: 'expo.out'
});
