A-Frame locomotion
A collection of A-Frame components, systems and primitives that enable all sorts of locomotion in VR. It't built to be modular, flexible and easy to use. Currently supports smooth locomotion, snap turning and smooth turning. Besides the actual modes of locomotion, there are auxillary components to improve the locomotion experience like a vignette when moving, fading when snap turning and more.

Blog post describing the implementation: A-Frame Adventures 01 - Smooth locomotion and snap turning
Quick start
To add aframe-locomotion to your A-Frame project, all you have to do is load the aframe-locomotion javascript:
<script src="https://unpkg.com/[email protected]/dist/aframe-locomotion.umd.min.js"></script>
This will automatically register the components smooth-locomotion and snap-turn. These need to be attached to the controllers as part of a camera rig, as follows:
<!-- Camera rig -->
<a-entity id="rig">
<a-camera id="camera"></a-camera>
<!-- Hands -->
<a-entity
hand-controls="hand: left"
locomotion="target: #rig; reference: #camera">
</a-entity>
<a-entity
hand-controls="hand: right"
snap-turn="target: #rig; reference: #camera">
</a-entity>
</a-entity>
Both smooth-locomotion and snap-turn have more properties that can be used to tweak the behaviour. Check the Documentation to learn more or explore the examples.
