javascript - 如何在 GSAP 中结合交错和时间线

Question

尝试实现交叉淡入淡出 slider ，如 http://css3.bradshawenterprises.com/cfimg/#cfimg3 所示使用GSAP，我能够为一张幻灯片制作动画，而无法为其他幻灯片制作动画，基本上很难将时间线和交错结合起来

代码笔:https://codepen.io/shmdhussain/pen/MvjEom `

// instantiate TimelineMax
const tl = new TimelineMax({  repeat: -1 });

    tl.to('.test', 2, {opacity:1, scale:1, ease:  Power0.easeNone})
    .to('.test', 4, {scale:1.5,ease:  Power0.easeNone}, ) 
    .to('.test', 2, {opacity: 0, scale:1,scale:1,  ease:  Power0.easeNone});

img{
/*   width:100%;
  height:100%; */
  position:absolute;
  top:0;
  left:0;
}

img:first-child{
  position:relative
}

div{
  width:400px;
  height:200px;
  overflow:hidden;
  position:relative;
}
.test{
  //opacity: 0;
}

<div>

您可以尝试使用位置参数或交错方法来创建重叠。尽管根据您的代码，位置参数似乎是更好的选择:
