滑动轮播 + 动画 + 遮罩图像

Question

我正在构建顶部有框架的 Swiper 旋转木马（由鼠标滚动触发）。这就是设计

红色是应该覆盖轮播的框架。中间的洞是透明的

我试过把红色图片做成mask-image，这样我就可以通过鼠标滚动来控制swiper carousel，但是中间的孔变白了，红色是透明的！而我想要的恰恰相反，我想要的是孔移植，孔外是红色。

请问有什么方法可以在滑动条轮播的顶部添加图片框，并且仍然可以触发和控制位于框下的轮播？

代码：

// https://swiperjs.com/ 
// ===================== -->

var mySwiper = new Swiper('.swiper-container', {
  // Optional parameters
  direction: 'horizontal',
  loop: true,
  speed: 1200,
  grabCursor: true,
  mousewheel: true,

  // If we need pagination
  pagination: {
    el: '.swiper-pagination',
    type: 'bullets',
    clickable: true,
  },

  // Navigation arrows
  navigation: {
    nextEl: '.swiper-button-next',
    prevEl: '.swiper-button-prev',
  },

  on: {
    slideChangeTransitionStart: function() {
      // Slide captions
      var swiper = this;
      setTimeout(function() {
        var currentTitle = $(swiper.slides[swiper.activeIndex]).attr("data-title");
        var currentSubtitle = $(swiper.slides[swiper.activeIndex]).attr("data-subtitle");
      }, 500);
      gsap.to($(".current-title"), 0.4, {
        autoAlpha: 0,
        y: -40,
        ease: Power1.easeIn
      });
      gsap.to($(".current-subtitle"), 0.4, {
        autoAlpha: 0,
        y: -40,
        delay: 0.15,
        ease: Power1.easeIn
      });
    },
    slideChangeTransitionEnd: function() {
      // Slide captions
      var swiper = this;
      var currentTitle = $(swiper.slides[swiper.activeIndex]).attr("data-title");
      var currentSubtitle = $(swiper.slides[swiper.activeIndex]).attr("data-subtitle");
      $(".slide-captions").html(function() {
        return "<h2 class='current-title'>" + currentTitle + "</h2>" + "<h3 class='current-subtitle'>" + currentSubtitle + "</h3>";
      });
      gsap.from($(".current-title"), 0.4, {
        autoAlpha: 0,
        y: 40,
        ease: Power1.easeOut
      });
      gsap.from($(".current-subtitle"), 0.4, {

        delay: 0.15,
        ease: Power1.easeOut
      });
    }
  }
});

// Slide captions
var currentTitle = $(mySwiper.slides[mySwiper.activeIndex]).attr("data-title");
var currentSubtitle = $(mySwiper.slides[mySwiper.activeIndex]).attr("data-subtitle");
$(".slide-captions").html(function() {
  return "<h2 class='current-title'>" + currentTitle + "</h2>" + "<h3 class='current-subtitle'>" + currentSubtitle + "</h3>";
});

我已经通过使用 GSAP 滚动触发器触发每一层的移动解决了我的问题，它对我有用。

let tl2 = gsap.timeline({

滚动触发器：{ 触发器：“#sec-4”，别针：真实的，擦洗：真实，

  start : "center center",
  end: "+=" + (window.innerHeight * 8),
}
  });
  tl2.from('.step-1', 1, {y: 100, opacity:0 })
  tl2.to('.step-1', 1, {opacity:0 })
  tl2.to('.flwres-frame', 0.5 , {x: -300}, 'frist')
  tl2.to('.girl-frame', 1 , {x: -300}, 'frist')
  tl2.from('.step-2', 1, {y: 100, opacity:0 }, 'frist')
  tl2.to('.step-2', 1, {opacity:0 })
  tl2.to('.flwres-frame', 0.5 , {x: -600}, 'second')
  tl2.to('.girl-frame', 1 , {x: -670}, 'second')
  tl2.from('.step-3', 1, {y: 100, opacity:0 }, 'second')
  tl2.to('.step-3', 1, {opacity:0 })
  tl2.to('.flwres-frame', 0.5 , {x: -900}, '3rd')
  tl2.to('.girl-frame', 1 , {x: -1050}, '3rd')
  tl2.from('.step-4', 2, {y: 100, opacity:0 }, '3rd')
