aframe-layout-component
Layout component for A-Frame.
Automatically positions child entities in 3D space, with several layouts to choose from. Define the layout on the parent entity:
<a-entity layout="type: line; margin: 2">
<a-box></a-box>
<a-box></a-box>
<a-box></a-box>
</a-entity>And then the positions will automatically be calculated and set:
<a-entity layout="type: line; margin: 2">
<a-box position="0 0 0"></a-box>
<a-box position="2 0 0"></a-box>
<a-box position="4 0 0"></a-box>
</a-entity>As entities are added or removed, the layout component will trigger a reflow on the positions.
We move then entire group around while maintaining the layout:
<a-entity layout="type: line; margin: 2" position="0 5 -5">
<a-box position="0 0 0"></a-box>
<a-box position="2 0 0"></a-box>
<a-box position="4 0 0"></a-box>
</a-entity>Properties
