No way to detect pointer "misses"

[drew-512]

Hi Nova,

Currently trying to work out how to detect when a pointer event does not get a hit so we can perform our own handling. Putting a large "background" UIBlock is not possible. Interaction.Point() currently does not return any hit information. Sadly, the functions it contains are private -- cmon guys.

Suppose I make GetHits()public, is my best path to call GetHits() and if I get a hit, then invoke the second half of Interaction.Point()?

Would be nice if y'all consider interoperability items like this -- stuff that makes a UI be flexible while not relying on someone having to use Nova for everything (or else you have to amend someone else's framework). Please at least make functions internal so people can extend Nova instead of having to maintain edits on your codebase.

Are you looking for something along the lines of the options described here?

Appreciate the prompt response.

So is the suggestion is to do a full UI raycast before invoking Interaction.Point()? To be honest, it doesn't feel great to be doing twice as much UI raycasting per frame.

There are a few options listed, so the suggestion is to pick whichever one best suits your use case.

For what it's worth, Interaction.Raycast() is pretty fast -- worst-case (i.e. casting against a lot of elements) performance is far closer to Unity's Physics.Raycast than their UI GraphicsRaycaster system.

Yeah, there are a lot of UIBlocks and not looking to do an unnecessary raycast every frame on mobile.

It would be much appreciated if the static util procs in Interaction.cs were made internal or class Interaction is made partial so that calls to those util procs are possible via a Nova namespace extension.
