sprite-draggable

let sprite can draggable，让sprite对象拥有draggable的能力

运行demo

npm install

npm start

访问 http://localhost:9092 查看具体demo

安装sprite-draggable依赖

  npm install sprite-draggable --save

作为spritejs插件使用

  // draggable与droppable方法注册到BaseSprite上
  import { install } from 'sprite-draggable'
  spritejs.use(install);
  …

  let group = new Group();
  group.draggable();
  // group.draggable(false); group.draggable({destroy,true}) 取消注册drag

  group.dropabble()//注册drop事件

  // group.droppable(false) ;group.droppable({destroy:true}) 取消注册drop

  group.on('drag', (evt) => {
    console.log('drag')
  });

  group.on('drop', (evt) => {
    console.log('drop')
  });

  group.on('dragenter', (evt) => {
    console.log('dragenter')
  });

  group.on('dragleave', (evt) => {
    console.log('dragleave')
  });

  group.on('dragover', (evt) => {
    console.log('dragover')
  });

  let sprite = new Sprite();
  //表示在 [0,0] 与 [300,300] 这两点矩形之间拖动 [xmin,ymin,xmax,ymax]，不设置表示不控制拖动范围
  sprite.draggable({dragRect:[0,0,300,300]})

  // 取消设置dragRect方法
  //sprite.draggable({dragRect:[0,0,300,300]})

  //表示拖动的范围大于坐标[0,0]
  //sprite.draggable({dragRect:[0,0]});

  /**拖动过程中，有三个事件 dragstart、drag、dragend**/
  sprite.on('dragstart',function(event){
    console.log('dragstart');
  });

  sprite.on('drag',function(event){
    console.log('drag');
  });

  sprite.on('dragend',function(event){
    console.log('dragend');
  });


  //取消元素拖动
  sprite.draggable(false);

作为方法使用

  import { draggable, droppable } from 'sprite-draggable'

  …

  let group = draggable(new Group());

  // draggable(group,false); draggable(group,{destroy,true}) 取消注册drag

  dropabble(group) //注册drop事件

  // dropabble(group,false) ;dropabble(group,{destroy:true}) 取消注册drop

  group.on('drag', (evt) => {
    console.log('drag')
  });

  group.on('drop', (evt) => {
    console.log('drop')
  });

  group.on('dragenter', (evt) => {
    console.log('dragenter')
  });

  group.on('dragleave', (evt) => {
    console.log('dragleave')
  });

  group.on('dragover', (evt) => {
    console.log('dragover')
  });

  let sprite = draggable(new Sprite());

  //表示在 [0,0] 与 [300,300] 这两点矩形之间拖动 [xmin,ymin,xmax,ymax]，不设置表示不控制拖动范围
  draggable(sprite,{dragRect:[0,0,300,300]});
  //draggable(sprite,{dragRect:[]});

  //表示拖动的范围大于坐标[0,0]
  //draggable(sprite,{dragRect:[0,0]});

  /**拖动过程中，有三个事件 dragstart、drag、dragend**/
  sprite.on('dragstart',function(event){
    console.log('dragstart');
  });

  sprite.on('drag',function(event){
    console.log('drag');
  });

  sprite.on('dragend',function(event){
    console.log('dragend');
  });


  //取消元素拖动
  draggable(sprite,false);
