    Has anyone used the new Unity Input system for their UI?
    I keep getting this error
    MissingMethodException: UnityEngine.InputSystem.UI.InputSystemUIInputModule.OnPoint Due to: Attempted to access a missing member

    This is most likely coming from PlayerInput and InputSystemUIInputModule sitting on the same GameObject. What I assume is what happens is that PlayerInput is set to SendMessage. So when it sees a UI action happening, it sends a message which then erroneously finds messages like OnPoint in InputSystemUIInputModule. However, those messages have incompatible signatures and thus the error (expressed as a rather misleading MissingMethodException).

    Workaround would be to either switch PlayerInput to using UnityEvents or to put the PlayerInput component on a GameObject separate from the event system.

    I'll make a note for us to have a look how to handle or at least detect this better.

    Is there any update on this in the past year?

    I spent the last week switching to the new PlayerInput system... finally got everything working fine...

    However, when the game is paused in the options menu, if any of the 12 "mapped" keys/buttons is pressed, i get a dozen MissingMethodException errors at once...

    I would like to avoid re-doing everything using UnityEvents instead of the currently set "Broadcast Message"...
