Hands non-proportional to head

[theWyattchannel]

So I just recently tested this thingy out, it's pretty cool!

There are a few things that are pretty janky with it though:

• The Y and X rotations are swapped???
• When running in VR mode, the head rotation is NOT synced up to the screen, causing a lot of screen jitter

But once I the rotations for the head setup, it was decent except for... the jitter. idk how to fix it unless I use some sort of easing because it is jittering like none other. The hands worked fine rotation wise, but when I had everything set-up, the hands were in a completely different area compared to the head, and were also not proportional to where my hands were in the current area. If there is a way for this to get fixed, please tell me!

• The Y and X rotations are swapped???

If I remember correctly, X and Y rotations are reported exactly as WebXR specifies. Depending on the coordinate systems used in your Scratch project, your implementation may require swapping X and Y rotations. It may be confusing because rotation is around the specified axis, not along the specified axis. Since the Y axis points up and down, rotation about the Y axis is yaw, rotation about the X axis is pitch, and rotation about the Z axis is roll. Hope this helps.

• When running in VR mode, the head rotation is NOT synced up to the screen, causing a lot of screen jitter

Can you give further details? Headset rotation is also reported exactly as WebXR gives. The raw data is NOT interpolated/smoothed, so the "screen jitter" you might be describing is likely caused by tiny movements of your head being tracked. What do you mean by the rotation is not synced to the screen? headset rotation could look weird if your renderer uses a different field of view than the extension's field of view. Try plugging the camera FOV reporter block into your renderer's FOV, and see if that improves the experience.

Let me know if you have any more questions or if I can help you with anything else! I'm out of town at the moment so I won't be able to test on a physical headset but I'll try to help you the best I can with the limited time I have.
I'm still working on ironing out the final issues of this extension, so bugs may occur. Thanks for the support.

As far as the issue with hand positioning: check to make sure you re-center your headset (if you're using Oculus, just press and hold the Oculus/Meta button or similar). I can't think of something else since the controllers report the position that WebXR gives. I don't know if I can think of any other reason why they would be significantly off other than the headset controller tracking isn't working at the hardware level. I'd like to do some testing to help you out more but I don't have access to my headset right now
