# drag

Fires on `mousemove` / `touchmove`.

***

The callback has two parameters which returns the orignal event and coordinates of the selection area (lasso) as an `Object`.

```javascript
selectable.on("drag", function(e, coords) {

});
```

The `coords` parameter returns an `Object` of the following format:

```javascript
{
    x1: Number, // the origin x offset
    y1: Number, // the origin y offset
    x2: Number, // the x offset from x1
    y2: Number, // the y offset from y1
}
```

```
x1,y1 (origin)
