Bug: Errors in WebXR Samples - Controller State #34

Closed De-Panther closed 5 months ago

De-Panther commented 9 months ago

When using the Controller State sample https://immersive-web.github.io/webxr-samples/controller-state.html First there's an error

motion-controllers.module.js:120 Uncaught (in promise) Error: No matching handedness, , in profile generic-hand

And when entering the XR session, the hands poses are tracked, but not the joints or pinch input.

The hand in this sample is not animated on device or through IWE. There is no implementation to animate the hand mesh in the sample's source code. But something is definitely wrong with buttons exposed through emulated hand tracking, I will fix it.

IWE?

I think that the first issue, is that while in inline session, the emulator is trying to run other sessions operations, like _checkInputSourcesChange. And I guess that once there's an error, other stuff stops working as intended.

It's indeed curious.. it seems to be a bug in the WebXR polyfill library that the emulator is using, I will patch that up.

IWE == Immersive Web Emulator

The fix has been landed into the main branch. If you'd like immediate access, you can build from the source to obtain the patch. Otherwise, it will be included in the upcoming v1.4.2 release.

Thank you for bringing this issue to our attention.
