# 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
```javascript
// 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
```javascript
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);
```
### 事件列表：
| 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 | |
