Hello! It’s problem of focusing on widgets. If you click and move cursor, your camera will work.
Unfortunately there is no way to get focus on a widget and move camera at the same time. If don’t set focus on a widget, you can move camera, but can’t click on an answer. To be precise you can, but it will be 2 clicks: 1st - gets focus(and from this moment you cant move your camera), 2nd - click on an answer.
With gamepad it works good.
Hm, might be using WidgetComponent insted of UserWidget can solve your problem? Try it
