onWheel delta doesn't match event.delta?

[mpolichette]

Hey, I'm using "react-use-gesture": "^6.0.7" and I'm getting a weird behavior with onWheel and a stepped mouse, e.g. one which physically click between steps.

I first noticed, I was not getting any movement if i did a single step of the wheel. Investigating, I defined the following handler: useGesture({ onWheel: console.log }) and got the following event.

As you can see, the event.deltaY has a value, but the delta from useGesture is 0. This isn't an issue if I scroll more quickly and get multiple events.

I've noticed this also effects my macbook trackpad w/ very small movements, but its harder to trigger a single event, so its less noticeable.

Any thoughts on why the delta doesn't reflect the events or ideas for how I could recognize these small movements?

@mpolichette hm this looks like a bug, thanks for reporting this, I’ll investigate this tomorrow.

Thanks @dbismut, you're a great maintainer! 👍

@mpolichette thanks, that's good to hear! 6.0.10 is out and should fix this. It's actually a bigger issue than I initially thought, it actually applies to scroll as well and to offset and movement state attributes. I also did some refactoring so hopefully this doesn't break elsewhere!

@dbismut I'm pretty new to this stuff, so sorry if this is not the place to comment this. But I think after this change been applying since 6.0.8, the scroll movement has getting some "jiggle" behavior, because that's kind of difficult to explain, I was testing this example from drcmd (https://codesandbox.io/embed/react-three-fiber-suspense-gltf-loader-l900i ). If you change the version from 6.0.7 to any number above, the behavior change, and is very clear if you click on a seat becuase now the click move the model.

@abepuentes Damn you're right. I though I could solve this in a minor release, but I'll release a cleaner 6.1.0 which might result in some minor breaking changes. Anyway 6.0.11 is released and should the issue with previous.

@dbismut 6.0.11 is working fine, I test it in my website and is ok. You are doing a great job.
