Question Having buttons reacting to mouse on new input system.

There are probably other posts talking about this, but I couldn't find exactly what I was wishing for.

I'm trying to make buttons on my game UI work just like they did on the old unity input system but on the new.

I don't quite understand how to set their values should I set up on the input manager and how to make them work over the buttons.

I've tried setting an input on the Mouse Delta but even when I didn't set anything at all on code about the input, Unity keeps giving me errors, I simply don't understand.

 

Have you checked the manual?
https://docs.unity3d.com/Packages/com.unity.inputsystem@1.0/manual/UISupport.html

What errors do you get exactly and what are you trying to do?

 

I have tried using Mouse Position and Mouse Delta.

Update:
I've noticed my MouseCursor 'action/input' had a 'press' interaction, after removing it my buttons now detect the mouse, but the error still appears.

Also, when I highlight another button, the button I have selected with my arrow keys doesn't deselect. When I click on a button it also gets 'selected' forever. (I'm using mouse/keyboard).

Thanks for your attention!
