Question How to replicate functionality from the old EventSystem.IsPointerOverGameObject?

I'm trying to replicate this line with the new UI toolkit.

Code (CSharp):

1. if (EventSystem.current.IsPointerOverGameObject())
2.         {
3.             return;
4.         }

Any advice is appreciated.

 

It's the same function, you need to set visibility to hidden to have this return false.

 

I can't set the UI visibility to hidden as I have them persist all the time.

In UnityUI I could use this and if my persistent UI was in the top left corner, I basically just couldn't click the top left corner and I was happy. But with UI Toolkit it feels like even my limited UI in the top left corner triggers this block of code even if I click in an area that no UI is present.

Any thoughts?

 

In my UI I have 3 panels:



The 3D clickable area is covered by the middle panel:



It also contains all kind of dialog boxes and popups, and whenever I open one then I toggle its visibility, if I changed the display then the bottom panel would move under the top panel which is not what I want.

 

We started with the same approach as you @dlorre, to put all permanent UI into one panel and fill the whole screen with it.

We had issues with clicks not being received on game objects because of it and therefore, separated all permanent UI elements into their own uxml files. We positioned them with margin set to auto (e.g. your bottom-panel should have margin-top: auto).

EventSystem.current.IsPointerOverGameObject() works as expected. The only thing that you should keep in mind is, that if you use e.g. IPointerEnterHandler with PolygonCollider2D, the colliders are also treated as UI and IsPointerOverGameObject will return true if you are over a collider. To solve this, we keep track, if the mouse is over a PolygonCollider2D by simply setting a flag to true/false when entering/exiting a collider.

 

Sorry, this is not my approach, I have 3 panels not one and I have no issues with clicks because the middle panel is hidden and thus, lets the click go through.

I apologize if I did not explain this correctly.
