Problem with mouse.

Hi guys, i created a inventory in my game, but I have a problem. When i click with the mouse on the button its doing nothing, no click animation, nothing… Can someone help my? Whats the problem? Thank you!

assuming you have created functionality in your widget for the button like ‘on clicked’ etc

you may need to use one of these:
when you set your widget - add to viewport usually

possibly this one:
(or just set input mode UI)(whichever works for you)
