最近朋友圈被很多网易云音乐的年底歌单给刷屏了, 我也去看了我的年度歌单, 发现一个有意思的交互成果, 抉择卡通形象, 通过滑动抉择人物的不同头像, 衣服, 裤子 最终塑造成一个领有独立共性的卡通形象.

制作素材

把每个滑动的图片进行了全屏截图, 而后通过图片解决工具去除背景, 制作成对立大小的 png 图片.



图片的卡通元素都是通过截图获取, 每个元素被解决成对立大小, 局部会有锯齿, 仅供参考. 这里头部比拟非凡, 每个形象的头部大小不一, 这里取一个对立的截止线, 不便前面整合成整个形象. 其它相似, 顶对齐即可.

剖析交互的特点 

1. 轮播图
2. 跨屏
3. 滑动循环
4. 局部衣服滑动会触发裤子的扭转
5. 局部裤子滑动会触发衣服的扭转
6. ...


轮播图代码 

<div id="slide" class="bui-slide bui-slide-skin01"></div>
var uiSlide = bui.slide({
        id: "#slide",
        height: 320,
        // autopage: true, // 主动分页
        data: [{
            image: "images/banner01.png",
            url: "pages/ui_controls/bui.slide_title.html",
        }, {
            image: "images/banner02.png",
            url: "pages/ui_controls/bui.slide_title.html",
        }, {
            image: "images/banner03.png",
            url: "pages/ui_controls/bui.slide_title.html",
        }],
        loop: true, // 循环
    })

跨屏轮播图只需加上 cross:true 参数即可. 相熟 BUI 的敌人, 一眼就能找到相似的成果, 跨屏轮播图 第 1 - 第 3 的特点就解决了.

有意思的是第 4 点第 5 点, 轮播图切换的时候局部须要互相关联.

实现的外围思路:

  1. 页面有一个动态全屏轮播图, 用于点击下一步, 上一步的整屏切换. 动态轮播图的益处是构造能够自定义.
  2. 首屏初始化三个跨屏轮播图, 用于头部, 衣服, 裤子的失常抉择切换;
  3. 点击轮播图的时候, 切换激活状态, 非激活状态暗藏左右两个图片 (暗藏通过 css), 并禁止滑动 ;
  4. 当滑动选中当前, 别离把头部, 衣服, 裤子的图片地址, 索引 缓存在 bui.store (轮播图的 to 回调外面);
  5. 通过 bui.store 创立衣服跟裤子的关联 conection 字段, 当检测到滑动的图片有配套裤子的时候, 主动滑动下一个轮播图到指定地位;
  6. 点击下一步去到第 2 屏, 用于展现刚刚选中的数据;
// 衣服
const cartoonBody = bui.slide({
    id: "#cartoonBody",
    height: 320,
    stopPropagation: false,
    autopage: false,
    cross: true,
    loop: true,
    data: this.$data.cartoon.body
}).on("to", function () {let index = this.index();
    // bui.store 读取的时候须要应用 this.$data.xxx , 如果应用 this.xxx 读取会导致最终的值不能设置正确.
    let img = that.$data.cartoon.body[index].image;
    // 设置
    that.profile.body.image = img;
    that.profile.body.index = index;

    // 检测衣服跟裤子的关系索引
    let item = bui.array.get(that.$data.conection, img, "body");
    let footindex = bui.array.index(that.$data.cartoon.foot, item.foot, "image");

    if (footindex >= 0 && that.$data.active[1] == "active-block") {
        // 操作裤子的实例, 跳转的时候, 因为 loop:true, 这里的索引须要在实在的索引下 +1 
        that.$data.distances[2].to(footindex + 1, "none")
    }

}).lock();// lock 禁止滑动
// 裤子
const cartoonFoot = bui.slide({
    id: "#cartoonFoot",
    height: 320,
    stopPropagation: false,
    autopage: false,
    cross: true,
    loop: true,
    data: this.$data.cartoon.foot
}).on("to", function () {let index = this.index();
    let img = that.$data.cartoon.foot[index].image;
    that.profile.foot.image = img;
    that.profile.foot.index = index;

    // 检测衣服跟裤子的关系索引
    let item = bui.array.get(that.$data.conection, img, "foot");
    let bodyindex = bui.array.index(that.$data.cartoon.body, item.body, "image");
    if (bodyindex >= 0 && that.$data.active[2] == "active-block") {
        // 操作衣服的实例, 跳转的时候, 因为 loop:true, 这里的索引须要在实在的索引下 +1 
        that.$data.distances[1].to(bodyindex + 1, "none")
    }
}).lock();// lock 禁止滑动
