在Vue3中如何实现类似fortnite.gg的图片自动切换效果？

<template>
  <div class="shop-card" v-for="item in items" :key="item.id">
    <div class="image-container">
      @@##@@
    </div>
    <div class="item-info-container">
      <p class="item-name">{{ item.name }}</p>
      <p class="item-price">@@##@@{{item.price}}</p>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      currentIndex: 0,
    };
  },
  mounted() {
    setInterval(() => {
      this.currentIndex = (this.currentIndex + 1) % this.item.images.length;
    }, 3000); // 每3秒切换一次
  },
};
</script>

<style scoped>
.image-container {
  position: relative;
  width: 200px; /* 调整图片容器宽度 */
  height: 150px; /* 调整图片容器高度 */
  overflow: hidden;
}

.item-image {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  object-fit: cover;
  opacity: 0;
  transition: opacity 0.5s ease-in-out; /* 添加平滑过渡动画 */
}

.item-image.active {
  opacity: 1;
  z-index: 1; /* 设置当前显示图片的 z-index */
}
</style>
