 2 | [![jsdelivr version](https://badgen.net/jsdelivr/v/npm/aframe-mouse-dragndrop-component)](https://cdn.jsdelivr.net/npm/aframe-mouse-dragndrop-component@1.0.4/dist/index.js)

 4 | # aframe-mouse-dragndrop
 5 | 
 6 | Drag-n-drop entites using mouse cursor.
 7 | 
 8 | ## implementation
 9 | 
10 | There's a new parameter in cursor component that we can use to monitor mouse interaction.
11 | 
12 | ```html
13 | <a-scene cursor="rayOrigin: mouse"></a-scene>
14 | ```
15 | 
16 | Based on this feature, we can intercept the event data emitting by the cursor component. [read more about cursor component](https://aframe.io/docs/0.9.0/components/cursor.html#intersection-data)
17 | 
18 | I've sperated this module into two sepearte component, **track-cursor** and **dragndrop**. And use dependencies to chain component startup. [read more about component dependencies](https://aframe.io/docs/0.9.0/core/component.html#dependencies)
19 | So you can add features like animation or hovering effects before draggin it.
20 | 
21 | When a draggable component is being hovered by the cursor, it will make the entity into tracking state. You can check it with
22 | 
23 | ```js
24 | if (this.el.is("tracking")) {
25 |   ...
26 | }
27 | ```
28 | 
29 | If a draggable component is being pressed, it will enter the dragging state. Likewise you can check it with:
30 | 
31 | ```js
32 | if (this.el.is("dragging")) {
33 |   ...
34 | }
35 | ```
36 | 
37 | If you want to do some startup/cleanup before entering/exiting these two states, be sure to listener to "stateadded"/"stateremoved" events.
38 | 
39 | ## usage
40 | 
41 | ```html
42 | <a-entity dragndrop></a-entity>
43 | ```
44 | 
45 | After adding the component, you can drag and drop it with mouse click.
46 | 
47 | ## additional features
48 | 
49 | 1.  When dragging the entity, look-controls on the camera will be temporary disabled.
50 | 2.  You can use mousewheel to send it further/closer when dragging.
51 | 
52 | Check out the live demo: [link](https://sassy-piper.glitch.me)
53 | 
54 | Appreciate any suggestions or feedback.
