A-Frame Exokit Avatars
This A-Frame component provides an easy way to integrate a full-body IK avatar in WebXR through my fork of the Exokit Avatars system.
Usage
The following is the most basic scene setup that will load in an avatar:
<!DOCTYPE html>

<a-asset-item id="model" src="./dan.glb"></a-asset-item>
</a-assets>
<a-plane id="ground" rotation="-90 0 0" color="green" height="10" width="10"></a-plane>
<a-light type="directional" intensity="0.5"></a-light>
<a-light type="ambient" intensity="0.5"></a-light>
<a-sky color="blue"></a-sky>
<a-entity avatar="model: #model"></a-entity>
<a-entity id="player">
<a-camera id="head" near="0.1" wasd-controls look-controls></a-camera>
<a-entity id="leftHand" tracked-controls="hand: left"></a-entity>
<a-entity id="rightHand" tracked-controls="hand: right"></a-entity>
</a-entity>
</a-scene>
</body>
</html>Considerations
- If implementing some form of touchpad or thumbstick movement, ensure your avatar is not parented under the player/camera rig object, as this will prevent the leg IK from functioning properly.
- By default, the
tracked-controlscomponent in A-Frame reports controller pose based on target ray space by default instead of grip space (refer to the WebXR Device API for more details). It's more than likely there might be some noticeable offset in the hand positions from where your controllers are. There is currently an open PR to let grip space be used for pose reporting, but in the meantime you may want to apply some manual offset to your controller pose to compensate.
