# aframe-click-drag-component
|
||||
|
||||
A Click & Drag component for [A-Frame](https://aframe.io).
|
||||
|
||||
Entities with the `click-drag` component can be click and dragged around the 3D
|
||||
scene. Even works whle the camera is moving!
|
||||
|
||||
_Note: entities are not positioned correctly when the camera is rotated._
|
||||
|
||||

|
||||
<script src="https://unpkg.com/aframe-click-drag-component"></script>
|
||||
<script>
|
||||
registerAframeClickDragComponent(window.AFRAME);
|
||||
</script>
|
||||
</head>
|

<body>
|
||||
<a-scene>
|
||||
<a-sphere click-drag position="0 1.25 -5" radius="1.25" color="#EF2D5E"></a-sphere>
|
||||
<a-camera look-controls-enabled="false"></a-camera>
