let @spritejs/next can draggable,让 sprite 对象拥有 draggable 的能力
npm install
npm start
通过浏览器访问可以查看具体 demo
npm install next-draggable --save
// draggable与droppable方法注册到Node上
import { install } from 'next-draggable'
install(spritejs);
…
let group = new Group();
group.draggable();
// group.draggable(false); group.draggable({destroy:true}) 取消注册drag
group.droppable()//注册drop事件
// group.droppable(false) ;group.droppable({destroy:true}) 取消注册drop

事件 | 描述 | 其它 |
---|---|---|
dragstart | 开始拖动对象 | |
drag | 正在拖动对象 | |
dragend | 停止拖动对象 | |
dragover | 一个 draggable 对象在另一个 droppable 对象上拖动 | |
dragenter | 一个 draggable 对象在进入一个 droppable 对象上 | draggable 进入 droppable 判断点为 draggable 对象最小矩形的中心 |
dragleave | 一个 draggable 对象离开一个 droppable 对象上 | |
drop | 一个 draggable 对象放在一个 droppable 对象上 |
