OverlapPoint ignoring the UI

Can OverlapPoint ignore UI elements? instead of passing through?

 

What part of the documented behaviour of OverlapPoint is surprising you?

eg,

"I have A and B in my scene and the documentation says OverlapPoint should do X.

But when I try it, I get Y instead."

 

Sorry, I didn't put it right, can OverlapPoint not ignore UI elements?
My case is that the control is done using OverlapPoint and when a window appears, OverlapPoint completely ignores the UI and when interacting with the UI, the character moves.

 

Are you talking about Physics2D.OverlapPoint() ??

What part of the documentation indicates it has anything to do with UI?

My reading is that it is a Physics2D function concerned with 2D colliders... or are you talking about some other method entirely?

 

I am guessing that you are calling PhysiscsOverlapPoint based on raw mouse state. As Kurt-Dekker said OverlapPoint said it has nothing to do with UI. Just like other XOverlap methods and XCast methods you are allowed can query the presence of physics coliders at any point of time at any position of world, it doesn't need to be performed on mouse position.

You probably need not to perform the OverlapPoint call and the related logic if you click UI. One of the simplest ways for doing that is adding transparent UI rectangle behind rest of the UI, that way when it receives mouse click event you know that you didn't click rest of UI which is on top of it.

It is probably also possible to do something using the Raycaster infrastructure (the ones that inherit from UnityEngine.EventSystem.BaserRaycaster and are attached to camera and canvas).

Depending on your needs it might be also possible to use IPointerClickHandler (and related interfaces) attached to objects with physics colliders. If I am not mistaken this approach should also take into account UI layering.
