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.

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/aframe-locomotion@0.2.0/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" position="0 0 0">
    <a-entity id="camera" camera position="0 1.6 0" wasd-controls look-controls></a-entity>

    <!-- Hands -->
    <a-entity
        vive-controls="hand: left"
        oculus-touch-controls="hand: left"
        locomotion="target: #rig; reference: #camera">
    </a-entity>
    <a-entity
        vive-controls="hand: right"
        oculus-touch-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.
