Bug: pointerover/pointerout fire twice when eventMode about pixijs

[joanjeremiah]

I would like to work on this.

I can verify the issue, but it looks like it might be intended functionality, and not a bug. The docs state that it will receive an extra event from the ticker when the mouse is not moving. Have you tried using eventMode = 'static'? This is the basic mode for interactions and should only fire once per event.

@joanjeremiah thanks for your reply!

Do you see what problem I might have in my reproduction attempt? I'm not sure why it doesn't render anything but it seems like the first step to getting this fixed. I found a couple problems but even after fixing them, still nothing renders.

This also affects Pixi 8.0.0-rc.5.

[Nantris]

I was able to fix my repro and it now demonstrates the issue. I hope somebody might be able to determine why this behavior occurs.

[Nantris]

Friendly bump. It seems really weird that no-one else is seeing (or at least reporting) this behavior.

[Nantris]

I didn't read the docs quite the same as you, but perhaps that actually is the right impression?

'dynamic': Emits events and is hit tested but will also receive mock interaction events fired from a ticker to allow for interaction when the mouse isn't moving

I read that as, it will fire either or, but not both. I guess it can be interpreted either way.

I did try static but for a graph layout where elements move, it feels bad when the interactivity doesn't occur when the element passes under the cursor.

[gabrielliwerant]

Hm, maybe there's a way to distinguish between the events with 'dynamic' and filter out the extras you don't want.

[Nantris]

Quite possibly. I didn't do an exhaustive search but I didn't readily see one.

I also tried debouncing and cancelling duplicated events. Perhaps I had an implementation error, but I couldn't get that work when it probably should.

[Nantris]

Friendly bump.

Can anyone from the team suggest whether this is the intended behavior or unintended behavior? I have to assume unintended.

[Nantris]

Anyone have any idea how to fix this? Can any maintainer comment on whether this is considered correct behavior?
